Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, the well-known functions or constructions are not described in order to simplify the gist of the present invention.

In addition, terms indicating a direction such as left, right, or upper side and bottom side in describing the present invention indicate relative directions as those described to clearly understand the present invention by those skilled in the art, and thus the scope of the right is limited. It will not be.

Then, with reference to Figs. 2 to 5, the configuration of an embodiment of the needle holder for micro site closure according to the present invention will be described in detail.

In addition, Figure 5 is a perspective view showing another embodiment of the needle holder for micro site closure according to the present invention.

As shown in Figures 2 to 5, one embodiment of the needle holder for micro site closure according to the present invention may comprise a holder body 100 and the holding unit 200.

Here, the holder body 100 is a component provided to enable the operator to hold an example of the needle holder for micro site closure according to the present invention, with only one hand or a few fingers without the incidental action such as pinching the finger. It is formed in a bar shape so that it can be gripped.

At this time, the thickness of the holder body 100 formed in a bar shape is advantageously formed as thin as a ballpoint pen or chopsticks for the micro site suture. (If only reference to what is shown in the drawings, the holder body 100 may be misunderstood as a thick, but the drawings are shown to illustrate the details of the invention in detail, one embodiment according to the present invention is used for micro site closure In view of the fact that it is sufficiently thin, those skilled in the art can predict sufficiently.)

However, it should be obvious that the operator should not be uncomfortable to grip. That is, it may take a long time to suture the micro site, the holder body 100 is advantageously designed not to give fatigue to the hand even if the operator gripping for a long time, for example, the inner shape of the hand held by the operator The curved surface 110 may be provided in correspondence with the curved surface 110.

In addition, the holder body 100 may be provided with a sliding switch 310 or a button switch 360 constituting the angle adjustment unit 300 to be described later, it is possible to turn on / off the electromagnetic force to the holding unit 200 The switch may be provided as shown in FIG. 2 or 5.

On the other hand, the holding unit 200 is a component for holding the needle (N), is mounted on the holder body 100 inclined at a predetermined angle.

First, the configuration related to holding the needle N by the holding unit 200 will be described in detail as follows.

Since the holding unit 200 is formed in a bar shape instead of a tong shape as mentioned in the background art of the present invention, in order to hold the needle N, the holding unit 200 is provided at one end of the holder body 100. The force to pull the needle (N) from the other end is to be applied.

The force that can be applied here may vary, but in one embodiment of the needle holder for micro site closure according to the present invention uses an electromagnetic force using an electromagnet. This is because the needle (N) is composed of a metallic material that can be affected by the electromagnetic force, because the electromagnetic force can be easily on / off according to the operator's intention.

However, when holding the needle (N) using the electromagnetic force in this way, it may be considered that there is a risk that the needle (N) can shake from side to side when passing through the micro site, the needle for micro site closure according to the present invention Since one embodiment of the holder presupposes the micro site closure to the last and will set the strength of the electromagnetic force in consideration of this risk, the aforementioned risk will not occur.

However, in consideration of such a risk, the needle N is inserted into one surface 230 of the holding unit 200 in contact with the needle N to prevent the needle N from shaking when passing through the micro site. Fixing grooves 232 that can be fixed may be provided.

At this time, the fixing groove 232 may be formed in any shape as long as the needle (N) is inserted and fixed. In addition, since the holding unit 200 is tilted or rotated to the left / right or up / down based on the virtual center axis C along the length direction of the holder body 100, as described later, There will be no restrictions like shape.

As described above, the holding unit 200 holds the needle N by using an electromagnetic force by the electromagnet, and the electromagnetic force is not applied only to one surface of the needle N that is in contact with the structural feature of the electromagnet. This may work, which may cause the operator to hold the needle (N) in the desired position.

Therefore, in order to prevent such a case, the other end of the holding unit 200 in which one surface of the needle N is in contact is wrapped with a member 220 that can block electromagnetic force on a portion other than the surface in which the needle N is in contact. It is advantageous.

That is, if the holding unit 200 is configured as a cylindrical as shown in Figures 3 and 4 except the surface that the needle (N) is in contact with the circumferential surface exposed to the outside wrapped with a member 220 that can block the electromagnetic force Since the electromagnetic force is applied to only one surface of the needle (N) contact.

Next, the holding unit 200 will be described in detail with respect to the configuration associated with being mounted inclined at a predetermined angle to the holder body 100 as follows.

If the holding unit 200 is composed of a portion formed by simply extending from the end of the holder body 100, the operator's wrist is limited to the angle of bending may limit the sealing range of the micro site, this restriction is Depending on the location, the operator can bring a lot of difficulty in suture.

In order to overcome this difficulty, in one embodiment of the needle holder for micro site sealing according to the present invention, one end of the holding unit 200 is configured to be inclined at a predetermined angle to the holder body 100.

At this time, there is no limitation with respect to the predetermined angle. For example, as described above, even if the holding unit 200 simply extends from the end of the holder body 100, if the operator can comfortably suture according to the portion where the micro site is located. It may be included in the range of the predetermined angle-in this case it will be 0 degrees based on the virtual central axis (C) in the longitudinal direction of the holder body (100).

As such, the holding unit 200 is mounted to the holder body 100 at an inclined angle at a predetermined angle, and may be manufactured by setting differently depending on the negative position in which the sealed micro site is located.

For example, by dividing the needle holder for cerebrovascular site closure, the needle holder for cardiovascular site closure, the operator can be commercialized individually by setting a predetermined angle at which the operator is most comfortable at the time of suture.

However, even if the product is individually manufactured by fixing at a predetermined angle as described above, it may be inconvenient in some cases. In one embodiment of the needle holder for micro site sealing according to the present invention, one end of the holding unit 200 is provided. The holder body 100 may be tilted left / right or up / down with respect to the virtual center axis C in the longitudinal direction, or may be configured to be mounted on the center axis C as a rotation axis.

In this case, the tilting to the left / right based on the central axis C may be confirmed from FIGS. 3 and 4, and the tilting up / down based on the central axis C may be confirmed from FIG. 5. Rotation based on C) can be seen from FIG. 2.

On the other hand, when one end of the holding unit 200 is mounted to the holder body 100 so as to be tilted, one embodiment of the needle holder for micro site sealing according to the present invention is the tilting angle of one end of the holding unit 200 Angle adjustment unit 300 for adjusting the may be further included.

Here, the angle adjusting unit 300 is a component for performing a function of adjusting the tilting angle of one end of the holding unit 200, if such a function may be configured in any structure.

However, if one embodiment of the needle holder for the micro site closure according to the present invention should be mounted inside the holder body 100 and becomes heavy due to the weight of the angle adjusting unit 300, the operator may use fatigue for a long time. May be increased.

Considering this point, for example with respect to the angle adjustment unit 300 more specifically described as follows.

For example, as shown in FIG. 3, the angle adjustment unit 300 may include a sliding switch 310, a rack 320, and a pinion gear 330.

Here, the sliding switch 310 is a component provided on the outer surface of the holder body 100 so that the operator can push or pull with the thumb or index finger while holding the holder body 100 with one hand.

In addition, the rack 320 is connected to the sliding switch 310 is provided on the inner surface of the holder body 100, to transmit the force to push or pull the sliding switch 310 provided from the operator to the pinion gear 330 to be described later It is the component that plays the role.

In addition, the pinion gear 330 serves to connect the rack 320 and one end of the holding unit 200 to push or pull the sliding switch 310 provided from the operator to be used to tilt the holding unit 200. It is a constitution.

As such, the angle adjusting unit 300 including the sliding switch 310, the rack 320 and the pinion gear 330, the operator pushes or pulls the sliding switch 310 with the thumb or index finger, the rack 320 When the linear movement of the pinion gear 330 rotates in response to the linear movement of the rack 320, the tilting angle of one end of the holding unit 200 is adjusted.

In another example, the angle adjusting unit 300 may be configured to include a motor 340, a controller 350 and a button switch 360, as shown in FIG.

Here, the motor 340 is a component that is provided to impart an electromagnetic force to the holding unit 200, that is, a component that receives and rotates a part of the power provided to operate the electromagnet. The motor 340 may be a factor of increasing the weight of the angle control unit 300 associated with the fatigue of the operator as described above, and does not require a large capacity to tilt the holding unit 200, It is advantageous to have a motor with a small weight and a small capacity, such as a motor.

In addition, the controller 350 is a component for controlling the rotation of the motor 340. The controller 350 may be configured separately from the motor 340 as shown in the drawing, but in some cases, the controller 350 may be included in the motor 340.

In addition, the button switch 360 is a component that can send an operation signal to the controller 350 instructing the motor 340 to rotate. The button switch 360 is configured in the form of pressing a button for the convenience of the operator, but is not limited to this can be modified in other forms, of course.

In this way, the angle adjustment unit 300 including the motor 340, the controller 350 and the button switch 360, the operator presses the button switch 360 with the thumb or forefinger to control the operation signal to the controller 350 When transmitted to, the motor 340 is rotated through the control of the controller 350, and thus the tilting angle of one end of the holding unit 200 is adjusted.

One embodiment of the needle holder for micro site closure according to the present invention as described above, unlike the example of the needle holder used for the conventional general suture described in the technology that is the background of the invention described above, There will not be a shortage of space to move and rotate the needle holder in suture.

Therefore, when using an embodiment of the needle holder for micro site closure according to the present invention, there is not enough space to move and turn the needle holder will not occur a situation that does not properly suture, accordingly the operator needle needle holder In order to make room for the movement and turn, it is inevitable that the situation of incision and opening of the tissue around the micro area will be unavoidable.

Although specific embodiments of the invention have been described and illustrated above, it is to be understood that the invention is not to be limited to the disclosed embodiment, but that various changes and modifications may be made therein without departing from the spirit and scope of the invention, It is self-evident to those who have it. Accordingly, such modifications or variations should not be individually understood from the technical spirit and viewpoint of the present invention, and modified embodiments should be included in the claims of the present invention.
