Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 relate to a first embodiment of the present invention, FIG. 1 shows a sterilizing cover before mounting together with an endoscope, FIG. 2 shows an endoscope apparatus having the first embodiment, and FIG. Shows the packaging state of the sterilization cover, and FIG. 4 shows the shape of the storage box of the sterilization cover.

As shown in FIG. 2, an endoscope apparatus 1 having the first embodiment is equipped with a medical sterilization cover (hereinafter, simply referred to as a sterilization cover) 2 of the first embodiment and the sterilization cover 2 attached thereto. For example, an optical rigid endoscope 3, a TV camera 4 that is detachably attached to the optical rigid endoscope (hereinafter, simply referred to as an endoscope) 3, and is not sterilized, A light source device 6 to which a detachable light guide cable 5 is connected to the endoscope 3, a camera control unit (hereinafter abbreviated as CCU) 8 to which a camera cord 7 of the TV camera 4 is connected, and this CCU 8 are connected. , And a TV monitor 9 for displaying an endoscopic image.

This endoscope apparatus 1 uses a medical instrument (also called a TV camera external scope or simply scope) in which a non-sterilized TV camera 4 is attached to a sterilized endoscope 3. It is used for diagnosing a diseased part or the like of interest in a living body of a patient or the like, observing inspection or the like, or for treatment using a treatment tool as necessary.

In this case, it is necessary to set the TV camera 4 at least in a state of being covered with the sterilization cover 2 (which has been sterilized in advance) and then to use it for diagnosis in order to prevent contamination and the like.

If the light guide cable 5 which is detachable from the endoscope 3 is not sterilized, it is necessary to use the light guide cable 5 covered with the sterilization cover 2 as well. The first embodiment can deal with the case where the light guide cable 5 is not sterilized. That is, a part of the endoscope 3 which is a sterilized medical instrument (is mounted on the endoscope 3) is a TV which is a non-sterile medical instrument.
The camera cover 4 side, including the light guide cable 5, is covered with the sterilization cover 2 so that the sterilization cover 2 can be attached and used.

The endoscope 3 has an elongated insertion portion 11, a grip portion 12 is formed at the rear end of the insertion portion 11, and an eyepiece portion 13 is formed at the rear end of the grip portion 12. There is. A detachable light guide cable 5 is connected to the grip portion 12. A light guide is inserted into the light guide cable 5, and the light guide connector 14 at the end of the light guide cable 5 is detachably connected to the light source device 6.

By connecting the light guide connector 14, the illumination light supplied from the light source device 6 is transmitted by the light guide inside the light guide cable 5 and is transmitted to the light guide side inside the endoscope 3. Then, the illumination light transmitted from the illumination window at the tip of the insertion portion 11 is emitted.

A subject such as a diseased part illuminated by the emitted illumination light is attached by an objective lens attached to the observation window at the distal end.
An optical image is formed at the image forming position. This optical image is transmitted to the eyepiece 13 side by an image guide such as a relay optical system inserted into the insertion portion 11 and can be observed with the naked eye through the eyepiece window of the eyepiece 13.

A camera head portion 15 of the TV camera 4 which has not been sterilized is detachably connected to the eyepiece portion 13. Inside the camera head portion 15, for example, C
A solid-state image sensor such as a CD 16 is housed, and the optical image transmitted to the eyepiece 13 side is formed on the CCD 16. This optical image is photoelectrically converted by the CCD 16, and the signal connector 17 is detachably connected to the CCU via the camera cord 7.
8 is input. The CCU 8 processes the signal, converts it into a standard video signal, and inputs it to the TV monitor 9,
An endoscopic image is displayed.

For example, one end is fixed to the rear end of the insertion portion 11 of the endoscope 3 (the TV camera 4 serving as a non-sterile medical instrument).
The sterilization cover 2 of the first embodiment, which is attached to the endoscope 3 and the TV camera 4 so as to cover the side thereof, has a thin synthetic resin sheet 21 formed into a cylindrical shape as shown in FIG. ,
It is connected to one end of this sheet 21, and this end is connected to the endoscope 3
And a storage box 23 for storing the compressed sheet 21 folded in an accordion shape (except in the vicinity of the portion connected to the fixture 22).

The storage box 23 is, for example, a hollow ring shape having a rotationally symmetrical ring-shaped storage section as shown in FIG. 4A, and has a cylindrical shape inside the inner peripheral surface of the storage box 23. An insertion portion having a size that allows the endoscope 3 (and the TV camera 4) to which the light guide cable 5 and the camera cord 7 are connected to pass through is formed in the space 24 in the central portion (or the central portion).

The storage box 23 is provided with a thin slit-shaped opening 25 through which the sheet 21 can pass. The opening 25 is provided in the vicinity of the boundary between the inner peripheral wall surface and the side wall surface of the storage box 23 in the shape of an annular ring that is rotationally symmetrical and has a thin thickness. The fixture 22 is connected to one end of the opening 25 that is exposed to the outside.

As shown in FIG. 1, the fixing member 22 is smaller than the space 24 serving as an insertion portion, and has an opening 25 having a rotationally symmetrical shape.
Since it is provided at one end that is pulled out a little from the
2 is set in the vicinity of the space 24 that serves as an insertion part, and this space 2
It is designed to be easier to mount than when it is not set near 4.

In this case, since the work for mounting the endoscope 3 on the extension area of the cylindrical space 24 (the area inside the inner peripheral surface when the inner peripheral surface of the storage box 23 is extended in the axial direction) is carried out, As shown in FIG. 1, even if the fixture 22 is not disposed inside the space 24, the space 24 is in the vicinity of the space 24 or the cylindrical space 24.
It may be arranged in the extension area of.

The sheet 21 is made of polyethylene, for example.
It is formed into a cylindrical shape with a thin synthetic resin such as vinyl chloride, polyurethane, or polyamide. The cylindrical shape of the sheet 21 may be any size as long as it allows the maximum area of the medical device to be covered.

This sheet 21 is made of an elastic material,
A material that does not have elasticity may be used, but it is preferable to have elasticity because it has advantages such as compactness when stored. Further, when the medical device is covered, even if the medical device has a size smaller than the maximum area portion, it can be stretched and passed if it has elasticity.

The fixture 22 connected to one end of the sheet 21 and fixing the one end to the endoscope 3 is preferably formed of an elastic synthetic resin having elasticity such as an O-ring or silicon.

The fixing member 22 is attached to one end of the sheet 21 by adhesion or welding, or connection by a rubber band, a rubber band, a spool, or the like. The fixture 22 has, for example, a ring shape having an opening at its center as shown in FIG. 4A, and the insertion portion 11 can be inserted into the opening.

Then, in the state shown in FIG.
The insertion part 11 is passed through the opening of the fixing part 22 and the fixing tool 22 is attached to the step surface between the rear end of the insertion part 11 and the front end of the grip part 12, as shown in FIG.
By setting such that one surface of the sterilization cover 1 is in close contact with the other surface, one end of the sterilization cover 2 is watertightly fixed (by the fixing tool 22).

Further, the inner peripheral surface of the opening of the fixing member 22 is in close contact with the outer peripheral surface near the rear end of the insertion portion 11 in a watertight manner.
It is also possible to fix one end of the. By fixing in a watertight manner, the inside and outside of the sheet covered with the sheet 21 can be more reliably separated (if not watertight) than that portion, so that the occurrence of contamination and the like can be prevented more reliably. Further, it may be fixed airtightly.

However, if the part fixed by the fixing tool 22 is not in a use condition where it is wet with a liquid at the time of use, it is necessary to be watertight because it is possible to prevent contamination even if it is not necessarily watertight. Not a requirement.

After fixing one end of the sheet 21 near the near side of the endoscope 3, the storage box 23 is moved to the near side by pulling the storage box 23 to the camera cord 7 side (that is, the right side in FIGS. 1 and 2). Or, if the endoscope 3 side is moved to the left side with respect to the storage box 23, etc.), the sheets inside the storage box 23 are successively fed out from the slit-shaped opening 25, and the endoscope 3 is moved to the endoscope 3. The connected light guide cable 5 and camera cord 7 can be easily covered.

In this case, the seat 21 is folded in an accordion shape inside the storage box 23, and the part folded near the opening 25 is connected to the seat 21 outside the opening 25. When moved as described above, the sheet 21 easily goes out.

Further, when the slippage of the sheet 21 is emphasized more, the surface of the sheet 21 is made to be satin, for example, and the contact area between the inner surface of the storage box 23 and the sheets which are folded and brought into contact with each other is made smaller to reduce friction. May be made smaller to make it slippery and easier to pull out.

Not limited to the satin finish, an uneven portion or the like may be formed on the surface of the sheet 21 so as to reduce the friction of the contacting portion, or the unevenness is formed on the sheet 21 so as to reduce the friction. As described above, a coating treatment film may be formed, or a coating treatment (to eliminate the difficulty of pulling out due to the ease of contact with each other due to the generation of static electricity) may be performed.

The storage box 23 may be moved rearward by pulling it back, or the like, until the sterilization cover 2 covers the necessary portion, or the pulling may be done until the internal sheet 21 is exhausted. The other end of the sheet 21 inside the storage box 23 may or may not be fixed to the inner wall surface of the storage box 23 or the like.

The other end of the sheet 21 is not fixed to the inner wall surface of the storage box 23, but an elastic ring is attached to the other end of the sheet 21 and the other end of the sheet 21 comes out from the opening 25 by the contracting force of the elastic ring. The end portion of may be fixed to the light guide cable 5 and the camera cord 7. Further, the other end of the seat 21 may be fixed by a fixing means such as a rubber band.

In the first embodiment, the work in the clean area for attaching the sterilization cover 2 to the endoscope 3 is carried out by attaching the fixing tool 22 to the sterilized endoscope 3 and storing the work in the unclean area. It is to receive the box 23 from the clean area and bring it to the rear end side. As described above, the mounting is easy, and the operation in the clean area, which is considered to be performed by the operator, is simplified, so that the operation time can be shortened.

FIG. 3 shows a packaging state of the sterilized cover 2 which has been sterilized. In FIG. 3A, the sterilization cover 2 is housed in a container 31 made of resin or the like, and is closed by a lid 32 made of, for example, thin resin. This lid 32 is EO
Sterile paper (instead of resin) may be used so as to be compatible with G (ethylene oxide gas) sterilization. Lid 3 when used
2 is opened and the sterile cover 2 is taken out and used.

Unlike FIG. 3A, FIG. 3B shows a packaged state in which the storage box 23 is exposed. Figure 3 (b0
Then, the shape of the storage box 23 is used, and the sterilization part is sealed with the plug 33 and the lid 34. The material of the plug 33 and the lid 34 is preferably an elastic member such as rubber.

It is also possible to add a mounting means such as a screw or snap fit to the storage box 23. Then, when the sterile cover 2 is attached to the endoscope 3, a person in an unclean area removes the stopper 33 and the lid 34, has the insertion section 11 of the endoscope 3 pass through the inside thereof, and goes to the rear as it is. It can be installed if

The packages shown in FIGS. 3 (a) and 3 (b) can be compactly stacked and placed, which has the advantage of requiring a small storage space.

For example, in FIG. 3A, the storage box 23 is formed of an elastic member, and the upper surface of the storage box 23 is pressed to compress the storage box 23 while the folded sheet 21 is stored. By sealing with 32, the size in the height direction may be smaller than that in FIG.

Further, in FIG. 3A, the storage box 23 is formed of an elastic member, and the space 24 can be collapsed by pressing from the lateral direction in a state where the folded sheet 21 is stored (or Even if the space 24 is not completely crushed, it may be compressed and stored so that the volume of the space 24 becomes small). When the storage box of the elastic member is used for compression as described above, the sterilization cover 2 can be stored more compactly.

FIG. 4A shows the shape of the storage box 23 of the sterilization cover 2 in the first embodiment as described above.
(B) shows the sterilization cover 2'of this modification together with the storage box 23 '. In this modification, a rectangular space 24 'is provided in the central portion (instead of the circular shape in FIG. 4A). Further, in this modification, a rectangular slit-shaped opening 25 'is provided.
Is provided. By forming the rectangular space 24 'in this way, the storage box can be made smaller (than in the first embodiment), and the handling and storage can be facilitated.

That is, in FIG. 1 or 2, the scope side has a shape that extends substantially in the axial direction of the insertion portion 11, and
Since the light guide cable 5 extends obliquely upward, there is a need for a space having a small horizontal (or horizontal) size and a large vertical size as an insertion portion. Therefore, instead of FIG. 4A, FIG.
Can be made compact.

The shape of the space on the center side of the storage box is shown in FIG.
Besides the rectangular shape of (b), a polygon such as a triangle may be used,
Other shapes may be used as long as the size that the scope side to be covered can pass through is secured. Alternatively, the storage box 23 may be formed of an elastic member so that the space of the insertion portion is deformed so that it can be passed through the scope side.

In FIG. 4, the sheet 21 is shown as being transparent. Normally, the transparent case is preferable because the position and state of the camera cable 7 inside the sheet 21 can be confirmed. It is also possible to prepare those having different degrees of transparency, those having different degrees of transparency by coloring, and those having different colors so as to correspond to the selection of an operator or the like. Further, it may be possible to provide a portion coated with a drug or the like that reacts with oxygen or the like in the air and changes its color in a certain time so that whether or not it has been used can be confirmed.

In this first embodiment, the seat 21 is compactly stored by folding it in an accordion shape in a storage box 23 having a space 24 through which the scope can pass, and the seat 21 is folded and stored. Since an annular opening 25 for easily and sequentially pulling out is provided, and the fixture 22 at one end of the seat 21 that is taken out from the opening 25 is arranged in the vicinity of the space 24, the scope insertion portion 11 is stored in the storage box. It can be fixed to one end of the seat 21 by the fixing tool 22 by passing it through the space 24 in the center of
By performing the work of moving 3 to the proximal side of the scope, the seat 21 stored in the storage box 23 can be easily pulled out, and the pulled-out sheet 21 covers the scope side.

Therefore, according to the first embodiment, the mounting work can be easily performed, and the mounting work can be completed in a short time. Also, the burden on the operator can be reduced,
It will also be possible to provide an environment in which we can concentrate on the original diagnosis. Moreover, since the structure is simple, the sterilization cover can be manufactured at low cost.

Although the fixing tool 22 is connected to one end of the seat 21 in FIG. 4 (a), etc., the fixing tool 22 is not connected to one end, and the insertion portion 11 of the endoscope 3 is connected to one end of the seat 21. When one end of the seat 21 comes close to the rear end (base end) of the insertion portion 11 through the sheet, the vicinity of one end of the seat 21 may be fixed to the rear end of the insertion portion 11 by a fixing member having elasticity such as a rubber band. .

In the first embodiment, the case where the optical endoscope 3 is an optical rigid endoscope has been described, but the present invention can also be applied to a flexible endoscope having a flexible insertion portion. In the first embodiment, at least the insertion portion 11 of the (hard or soft) endoscope is used.
It is applicable when is sterilized or disinfected.

Next, a second embodiment of the present invention will be described. Figure 5

Similar to the sterilization cover 2 of the embodiment, the storage box 23 in the first embodiment is composed of the storage box 42 including the inner cylinder 42a and the outer cylinder 42b.

A cross section having a hollow portion is U-shaped (see, for example, FIG. 6).
A snap fit 43 protruding radially inward is provided at the end of the outer cylinder 42b (see (b)), and the snap fit 43 easily catches the end of the inner cylinder 42a extending radially outward. Can be joined (or engaged). The hollow portion of the outer cylinder 42b is slightly larger than the outer diameter of the cylinder portion of the inner cylinder 42a, and in the joined state as shown in FIG.
The slit-shaped opening 25 is formed in the ring-shaped gap between the cylindrical portion of 2a and the hollow portion of the outer cylinder 42b.

It is considered that the snap fit 43 is the easiest way to join the outer cylinder 42b and the inner cylinder 42a, but bonding, welding, screw fastening, screwing or the like is also possible.

FIG. 6 shows an essential part of a process of manufacturing the sterilization cover 41 of FIG. As shown in FIG. 6A, a rod-shaped jig 44 is inserted into the cylindrical sheet 21 having the fixture 22 attached to one end thereof, and the jig 44 is inserted into the inner cylinder 42a from the other end side (right side in the figure).
The inner cylinder 42a is put on the jig 44 by passing through. Then, when the inner cylinder 42a is moved in the leftward direction indicated by the arrow in FIG. 6A, the seat 21 is automatically folded into an accordion shape.

When the inner cylinder 42a reaches the position of the end of the jig 44, the outer cylinder 42b is covered as shown by the arrow in FIG. 6 (b). In this case, the snap fit 43 causes the inner cylinder 42 to

After covering the camera cord 7 and the light guide cable 5 as shown in FIG.
If the light guide connector 14 is wider than the space 25, the storage box 23 can be detached from the camera cord 7 and the light guide cable 5 by separating it into two as shown in FIG. Further, when it is difficult to pass the light guide cable portion on the base end side of the scope into the space 24, the scope can be separated into two bodies and easily passed.

According to this embodiment, the storage box 23 does not get in the way, and the work of mounting or the like and the work of removing the sterilization cover are facilitated. Others have the same operations and effects as the first embodiment.

Although the sterilization cover described above covers the light guide cable 5 and the camera cord 7, it may cover only the camera cord 7 side (without covering the light guide cable 5) as shown in FIG. Okay, fig 1
As shown in FIG. 1, it can also be applied to the one that covers the dental treatment instrument 57.

The sterilization cover 56 of the fourth embodiment shown in FIG.
The basic configuration is the same as that of the first embodiment. The space 24 ′ of the storage box 58 in the sterilization cover 56 is sized so that the adapter 63 attached to the eyepiece portion 62 of the rigid endoscope 61 can be passed through, for example. The camera head portion 15 of the TV camera 4 is attached to the eyepiece portion 62 of the rigid endoscope 61 via the adapter 63.

When one side of the fixing member 22 ′, which is the inner side of the seat 21, is in contact with the front surface of the adapter 63, the inner wall surface of the opening of the fixing member 22 ′ becomes the enlarged diameter portion of the eyepiece portion 62. They are closely attached and can be fixed in a watertight manner. Others are the same as those in the first embodiment. Further, it has substantially the same effect as that of the first embodiment.

In the rigid endoscope 61, the light guide cable 5 is detachably connected to the mouthpiece portion of the grip portion 66 provided at the rear end of the insertion portion 65 formed of an elongated and hard outer pipe. It is like this.

The sterilizing cover 56 'shown in FIG. 11 has a size so that it can be closely fixed to the stepped portion of the dental treatment instrument 57.
The 2'opening is set. The space 24 ″ of the storage box 58 ′ is set to a size that allows the dental treatment instrument 57 to pass therethrough.

FIG. 11 shows the sterilization cover 56 'when applied to the dental treatment portion 57, but it is not limited to the surgical high frequency electrode,
It can also be applied to medical instruments such as water supply / suction tubes, scope holders, and surgical microscopes. This sterilization cover 56 'also has substantially the same operation and effect as the first embodiment.

FIG. 12 shows sterilization covers 71 and 71 'of the fifth embodiment and its modification. These sterile covers 71
And 71 'are, for example, those in which only the position of the slit-shaped opening 25 in the storage box 23 in the first embodiment is changed.

That is, the sterilization cover 7 shown in FIG.
In No. 1, a slit-shaped opening 25 is provided on the outer peripheral surface of the storage box 23, and in the sterilization cover 71 'shown in FIG. 12B, a slit-shaped opening 25 is provided on the inner peripheral surface of the storage box 23. . When the opening 25 is provided on the inner peripheral surface as shown in FIG. 12B, the fixture 22 can be completely inserted into the space 24, so that it can be made compact during packaging. Otherwise, the sterilization covers 71 and 71 'have the same operation and effect as those of the first embodiment.

FIG. 13 shows a sterilization cover 81 according to the sixth embodiment of the present invention. In this sterilization cover 81, the folded shape of the sheet 21 stored in the storage box 23 is different. In this embodiment, it is rounded into an annular roll (condom) shape and stored in the storage box 23. By doing so, the storage box 23 can be made compact. Others are first
The configuration is the same as that of the embodiment and has the same operation and effect.

FIG. 14 shows a sterilization cover 91 according to the seventh embodiment of the present invention. In this sterilization cover 91, for example, the fixing tool 22 in the sterilization cover 2 of the first embodiment is changed to an elongated tubular sheath 92 whose tip is at least transparent and sealed. One end of the seat 21 is fixed to the base end of the sheath 92 by a fixing ring or a stop ring 93.

The length of the sheath 92 is set to the length of the insertion part 11 of the endoscope 3. By inserting the insertion part 11 into the sheath 92, the insertion part 11 is inserted as shown in FIG. It is possible to cover the entire endoscope 3 and the TV camera 4 with the sterilization cover 91 such that the sheath is covered with the sheath 92 and the other portion is covered with the sheet 21. In this case, the transparent portion of the distal end surface of the sheath 92 ensures that the illumination light is emitted from the illumination window of the endoscope 3 and the incident light is incident on the observation window.

Therefore, even when the endoscope 3 and the TV camera 4 are not sterilized, the use of the sterilization cover 91 has an advantage that the endoscope 3 and the TV camera 4 can be used in substantially the same manner as in the case of being sterilized.

As a modification of FIG. 14, the base 92 of the sheath 92 and the end of the sheet 21 separated from each other may be fixed by a rubber band or other elastic fixing member. In this case, even when the length of the insertion portion on the endoscope 3 side to be covered and the size such as the outer diameter are different, it is possible to appropriately cope with it by changing the sheath to a corresponding one and using it. It will be possible. The other effects are almost the same as those of the sixth embodiment.

The sterilization cover used for isolation to prevent contamination is not limited to a non-sterilized or non-sterilized one, and can be used for an unwashed medical instrument.
