Description

[0001] Needle of surgical operation [

The present invention relates to a surgical needle, and more particularly, to a surgical needle capable of endoscopically sealing a cartilage tissue or a dry tissue.

In general, surgical needles are used to seal tissues such as incised skin, and are manufactured in various shapes. As an example of such a technique, Korea Patent No. 10-0319209 discloses a needlelayer having a needle A pair of guide grooves are formed on both right and left sides and an arc-shaped surgical double-headed needle having a predetermined curvature in which graduations are engraved so that the depth of entry into the tissue can be recognized at both ends.

On the other hand, recently, an endoscope capable of directly inserting and observing the tissue without incision has been developed, and an operation method that can be closed without incision using such endoscope is being developed.

However, in the case of a very narrow and narrow space, such as the flexor hallucis longus, the knee cartilage and the shoulder tendons, endoscopy is possible, but endoscopic closure of the tendon is impossible There is a problem in that it must be cut and cut again.

An object of the present invention is to provide a surgical needle capable of endoscopically sealing a tendon rupture.
It is also an object of the present invention to provide a surgical needle that enables continuous suturing without the aid of other tools within very narrow hay.

The present invention relates to a surgical needle having a sewing thread connected to an end thereof and inserted into a tissue to seal the tissue, the surgical needle comprising: a needle body having a predetermined length, one end being held by a user and the other being inserted into the tissue; And a connection portion formed at the other end of the needle body and connected to the suture thread, the needle body being bent and positioned at the other insertion end, and having an acute angle with respect to the outer circumferential surface to prevent damage to the tissue And a second bending portion formed at a rear side of the first bending portion and bent in a direction of suturing the surgical needle.

Here, the connection portion may be formed with a latching groove in which the suture thread is engaged and fitted.

Further, the tissue may be a cartilage tissue or a tendon tissue, and the cartilage tissue or the dry tissue may be sealed endoscopically.

It is preferable that the first bending portion and the second bending portion form a gently curved round surface on the outer side.

The needle body may be formed by bending the first bent portion and the second bent portion so as to be inclined in the clockwise direction with respect to the longitudinal direction or by the first bent portion and the second bent portion, It can be bent in an anticlockwise direction.

Furthermore, it is preferable that the surgical needle further includes a grip portion provided at the other end of the needle body, the grip portion being easily grasable by the user.

The surgical needle according to the present invention provides the following effects.

First, since the tendons can be continuously sewed endoscopically to the tendon rupture without cutting the skin, the risk of the surgery can be reduced.

Second, postoperative pain is less, recovery is faster, and there is almost no scarring, so it can provide a cosmetically better effect.

Third, it is easy to commercialize, it has good marketability, and its structure is simple and economical.

Fig. 2 is a perspective view showing the shapes of the first bent portion and the second bent portion shown in Fig. 1;
Fig. 3 is a perspective view showing another embodiment of the surgical needle of Fig. 1; Fig.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a surgical needle according to an embodiment of the present invention, FIG. 2 is a perspective view showing the shapes of the first bending portion and the second bending portion of FIG. 1, Fig.

Referring to FIG. 1, a surgical needle 400 according to an embodiment of the present invention is connected to a suture at an end thereof and inserted into a cartilage tissue or a tendon tissue to endoscopically seal the tissue A needle body 100, a connecting portion 200, and a handle 300. The surgical needle 400 includes a needle body 100, a connection portion 200,

The needle body 100 has a predetermined length, and one end of the needle body 100 is held by a user and the other end is inserted into the tissue.

Specifically, the needle body 100 has a first bent portion 110 and a second bent portion 120, and has a shape that is three-dimensionally bent like a screw.

Referring to FIG. 2, the first bent portion 110 and the second bent portion 120 will be described in detail.

First, the first bent portion 110 is bent and bent at an acute angle with respect to the outer circumferential surface to prevent damage to the tissue at the time of insertion into the tissue.

The second bending portion 120 is located behind the first bending portion 110 in the needle body 100 and is bent in an oblique direction in a sewing direction so that the gun can be easily sewn.

The angles at which the first bending portion 110 and the second bending portion 120 are bent are the angles at which the first bending portion 110 can prevent tissue damage during injection into the tissue, And the second bending portion 120 may be bent in an oblique direction in an oblique direction so as to facilitate sewing.

The first bending section 110 and the second bending section 120 may have rounded surfaces 111 and 121 having gentle curves on the outside thereof to prevent damage to the guns .

Meanwhile, in the needle body 100, the bending shape of the first bending portion 110 and the second bending portion 120 may be varied according to the right or left hand of the user.

For example, if the user is a right-handed person, the needle body 100 may be bent in an oblique direction with respect to the longitudinal direction by the first bending portion 110 and the second bending portion 120 So that the user of the handle can easily sew the suture.

3, when the user is left-handed, the surgical needle 500 is moved in a direction in which the first bending part 130 formed on the needle body 100 and the second bending part 140 And it can be bent so as to be inclined counterclockwise with respect to the longitudinal direction, so that a left-handed user can easily sew it. Reference numerals 131 and 141 denote rounded surfaces formed on the outer surfaces of the first bent portion 130 and the second bent portion 140, respectively.

The connection part 200 is formed at the other end of the needle body 100 and is connected to the suture thread.

Accordingly, the surgical needle 400 is structured such that the suture thread is connected to the surgical needle 400 through the hooking groove 210, unlike the conventional method in which the conventional suture thread 10 is inserted into the hole and is sealed. Guns can be sewn continuously in a narrow space of hay, which is cheap.

It is preferable that a hook or a triangular groove shape such as a nose nose of a crochet is applied so that the sewing thread can be continuously sewn by the suture thread, Various shapes can be applied.

The handle 300 is provided at the other end of the needle body 100 so that the user can easily grip the handle 300. A detailed description thereof will be omitted.

According to the above description, the surgical needle 400 can be stitched endoscopically through two small endoscopic holes without incision, thereby enabling minimally invasive tendon repair as well as providing less pain after surgery and quick recovery Can be pulled, scarcely scarcely occurs, and can provide a cosmetically effective effect.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
