Abstract

PROBLEM TO BE SOLVED: To provide a suture needle which can perform a suture operation of an Achilles tendon, etc., by a simple means and without leaving any mark as residue from the operation. SOLUTION: Points 2, 2 are provided at the ends of a needle body 1, and in the middle, a detention part for an operation thread consisting of a circumferential groove 3 or through hole 4 is furnished. If, for example, an Achilles tendon undergoes a suture operation, the needle body 1 at which an operation thread is detained, is plunged from outside the skin of the part mating with the rupture part of the Achilles tendon and intruded until the thread detention part crosses over the Achilles tendon substantially. Upon changing the heading, the body is intruded in the opposite direction and alike intruded so that the thread detention part crosses from the contrary side the Achilles tendon substantially. This operating cycle is repeated so that a zigzag suture line is completed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a needle used for suture operation when an Achilles tendon or the like is torn.

[0002]

2. Description of the Related Art For example, when the Achilles tendon is ruptured, in order to connect it, the skin,
The fat and cysts were incised and the Achilles tendon was sutured directly with surgical thread. As described above, incision until reaching the Achilles tendon requires deep anesthesia, which requires hospitalization, and it takes time and effort to suture the incision and the incision and suture the Achilles tendon, and there is a problem that an incision scar remains on the skin. .

[0003]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a suture needle capable of easily performing a suturing operation on a tendon or the like and leaving no surgical scar.

[0004]

In order to solve the above-mentioned problems, the surgical suturing needle of the present invention adopts a construction in which points are provided at both ends of the needle body and a surgical thread locking portion is provided in the middle portion. is there.

The locking portion may be a groove or a radial through hole provided on the outer circumference of the needle body.

[0006] A surgical thread is locked to the locking portion of the needle body, a suture needle is pierced directly from the skin in the transverse direction of the ruptured tendon, and the surgical thread is pushed until it substantially crosses the Achilles tendon. Then, push the suture needle in the opposite direction, and push it in until the locking portion of the surgical thread similarly crosses the Achilles tendon. By repeating this, a zigzag suture line is formed with a surgical thread, and the tendon is joined.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the suture needle of the present invention is provided with sharp points 2 and 2 at both ends of a rod-shaped needle body 1, and a surgical thread locking portion, for example, a circumferential groove, is provided at an intermediate portion. 3 or a through hole 4 in the radial direction is provided. This locking part
It is preferable to be in the center of the needle body 1, but it is not always necessary to be in the center. Further, both the circumferential groove 3 and the through hole 4 may be provided in the locking portion. In addition to the above, the locking portion may have various shapes and structures such as making the portion flat.

The overall shape of the needle body 1 is not limited to a straight line shape, but may be an arcuate shape or an arcuate shape, and the cross-sectional shape is not limited to the illustrated circular shape, but may be any shape such as an elliptical shape or a polygonal shape. You can choose.

An example of using the suture needle as described above will be described with reference to FIGS. 3 and 4.

First, one end of the surgical thread 5 is firmly locked to the locking portion 3 (4). Then, the needle body 1 is pierced from the outer surface of the skin B corresponding to the Achilles tendon A, and is made to protrude from the skin B on the opposite side through the fat layer C, the cyst sac D, and the Achilles tendon A, and further the surgical thread 5 from the skin B on the opposite side. Locking part 3
Push (4) until it crosses Achilles tendon A at least.

Therefore, as shown by the chain line in FIG. 4, the direction of the needle body 1 is changed, and this time the needle body 1 is pushed in the opposite direction to the above, and the locking portion 3 (4) of the surgical thread 5 is placed on the left side of FIG. ) Crosses the Achilles tendon A. Then, the direction of the needle body 1 is changed, and the needle body 1 is pushed rightward.

By repeating the above-mentioned operation, the surgical thread 5 forms a zigzag suture line over the ruptured portion A'of the Achilles tendon A, and this is performed twice in the vertical direction, and the suture line as shown in FIG. The fractured portion A'is joined.

By the above operation, the needle body 1 only forms a thin hole in the skin B, and a wound caused by this is soon healed and is not noticeable at all.

The suturing needle of the present invention can be used not only for suturing not only the Achilles tendon but also other tendons, as well as for suturing muscles and the like.

[0016]

As described above, according to the present invention, since the points are provided at both ends of the needle main body and the surgical thread locking portions are provided at the intermediate portion, a zigzag suture line can be formed on the inner surface of the skin. For example, when performing an Achilles tendon suturing operation, there is no need for incision, no deep anesthesia is needed, and local anesthesia is sufficient, so there is no need for hospitalization, and surgery is simple and no surgical scars remain.
