JPH0956720A - Medical strait suturing needle with loop suture - Google Patents

Abstract

PROBLEM TO BE SOLVED: To suture at health tendon part even if the length till a health tendon tissue is long by forming a medical suturing needle which is a straight needle having a sharp top edge and fixing a thick nylon filament as a loop shape at another end. SOLUTION: The medical suturing needle is formed by using a straight needle having a sharp edge at one end and a thick nylon monofilament fixed as loop shape at another end thereof. For example, a needle with a loop filament is formed by fixing 3-0 or 2-0 nylon filament of about 30cm or 40cm length making a loop shape at the not sharp end of a straight needle of 3cm or 5cm length with a sharp edge. Using the straight needle with loop filament, the filament is penetrated into periphery stump from a peritenon A3 to a periphery by TSUGE method. Then, the needle is penetrated through A3 peritenon, A2 peritenon and A1 peritenon in the order and the side of the perphery is pulled into the center of the peritenon by drawing the filament. Then the filament is penetrated into the central stump of the tendon using TSUGE method and suture is conducted at the center of a given position from the A1 peritenon.

Description

Detailed Description of the Invention

A straight suture needle with a loop thread for medical use [Summary] As a suture thread used for suturing a tendon of a limb, a Tsushita-type needle with a loop thread is often used (Fig. 1). However, since this suture needle is curved, it is inconvenient to penetrate straight through a long tendon. For example, it is inconvenient to apply strong tension to the sutured part due to old tendon rupture, to require tendon transplantation, or to implant the tendon in an intraosseous tunnel. Therefore, in order to improve these problems, a straight needle with a length of 3 cm, 5 cm, 7 cm, and 10 cm was used instead of a curved needle, and a needle with a sharp tip was formed on the opposite side (blunt side). ) Was fixed with a looped nylon thread (Fig. 2). [Constitution] 30 cm or 40 cm long 3-0 nylon thread, 2-0 nylon thread or 1-0 nylon thread is looped to the blunt side of a straight needle having 3 cm, 5 cm, 7 cm and 10 cm tips. Eleven kinds of fixed straight needles with loop threads are prepared (Table 1).

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surgical threaded needle used for complicated tendon suture and tendon transplantation.

[0003]

2. Description of the Related Art Traditionally, as one of the tendon suturing methods, there is the Tsushita method using a Tsushita-type loop thread needle (FIG. 3). This Tsushita-type needle with loop thread is obtained by fixing a monofilament nylon thread with loop thread to the distal end of a curved needle having a length of about 15 mm.

[0004]

With a conventional curved needle in which a loop thread is joined, when the tension between the stumps of the ruptured tendon is extremely strong, or the stump of the sewn tendon becomes a necrosis, it is healthy. However, there are some inconveniences such as the long distance to the tendon tissue and the need for two tendons to be sutured by the conventional thread needle when the tendon is transplanted.

[0005]

The straight suture needle with loop yarn invented can solve these problems all at once. Further, in the case of tendon transplantation, conventionally, tendon sutures were required at two places, but this thread needle has an advantage that one suture is required.

[0006]

EXAMPLES OF THE INVENTION "No man's of a 56 year old man"
Land's flexion of the left flexor digital tendon. The degree of injury was severe in the state of incomplete amputation accompanied by vascular nerve injury by an electric saw. The flexor tendon was as shallow as possible in the flexor digital flexor tendon. The deep flexor tendon was sutured, and the skin incision was made from the wound to the point beyond the PIP joint.
A linear incision was performed, and using the invented 2-0 nylon loop threaded 5 cm long straight suture needle, as shown in FIG.
At the periphery of the tendon sheath, first pass the thread through the peripheral stump of the tendon by the Tsushita method, then insert this needle into the A3 tendon sheath, then the A2 tendon sheath, and then the A1 tendon sheath.
After passing through the inside of the tendon sheath, the thread is pulled and the distal side of the tendon is pulled into the center of the tendon sheath. Then, the central stump of the tendon is also shown in FIG.
2cm from the A1 tendon sheath through the thread by the Tsushita method
3 cm to the center. As a result, "no ma
In the flexor tendon in n's land ", the nylon thread does not appear in appearance because the nylon thread passes only inside the tendon (Fig. 7), and the adhesion is remarkably improved as compared with the case where the conventional tendon suture is present. It was found to contribute to.

[0007]

EFFECTS OF THE INVENTION According to the present invention, when the tension between the stumps of the ruptured tendon is extremely strong, or when the stumps of the sutured tendon are necrotic and the distance to the healthy tendon tissue is long, the healthy It became possible to suture the healthy tendon by passing a suture through the tendon to the tendon tissue. Further, in the case of tendon transplantation, compared with the conventional suture needle that requires two sutures, the present suture needle has the effect of requiring only one suture.
