Problems solved by technology

[0004] The present invention aims at the rupture of the Achilles tendon by means of the existing percutaneous suture device in the percutaneous minimally invasive suture operation, there are many knots at the broken end of the suture, and the uneven stress on each suture when the suture is tightened leads to tearing of the Achilles tendon and poor suture strength. To deal with poor problems, we provide a new type of Achilles tendon stapler, which combines the principle of Bunnel suture and utilizes the feature that Achilles tendon can slide relative to Achilles fascia, which can simplify the operation, ensure ideal suturing effect, and further reduce Advantages of Minor Surgical Incisions

Embodiment Construction

[0030] The present invention will be described below in conjunction with the accompanying drawings.

[0031] The present invention relates to a kind of Achilles tendon stapler, its structure is as follows: figure 1 As shown, it includes a first bracket 1 , a second bracket 3 , an elastic adjustment device, a first guide sleeve 7 , a second guide sleeve 11 , a first positioning cylinder 8 and a second positioning cylinder. Wherein the first bracket 1 and the second bracket 3 are connected by an elastic adjustment device, the first bracket and the second bracket are both U-shaped brackets, that is, both have U-shaped arms, forming the U-shaped arm outer arms of the first brackets distributed in sequence 20. The U-shaped inner arm 21 of the first support, the U-shaped inner arm 23 of the second support, and the U-shaped outer arm 22 of the second support.

[0032] The tightness adjusting device is used to adjust the degree of tightness between the first bracket 1 and the second ...

Abstract

The invention relates to an achilles tendon stitching instrument. The achilles tendon stitching instrument comprises a first bracket, a second bracket, a tightness adjusting device, a first guide sleeve, a second guide sleeve, a first positioning tube and a second positioning tube, wherein the first bracket and the second bracket are connected through the tightness adjusting device, a first positioning hole, a first guide hole, a second positioning hole and a second guide hole are respectively formed in the inner and outer arms of the U-shaped arms of the first bracket and the second bracket, the first guide sleeve is fixed through the first positioning hole, one end of the first guide sleeve is matched with the first guide hole, and one end of the first positioning tube penetrates into the interior of the first guide sleeve; the second guide sleeve is fixed through the second positioning hole, one end of the second guide sleeve is matched with the second guide hole, one end of the second positioning tube penetrates into the interior of the second guide sleeve, and through holes matched with an achilles tendon stitching needle are formed in the first positioning tube and the second positioning tube. With the adoption of the achilles tendon stitching instrument, the operation procedures are simplified, and ideal stitching effect is guaranteed.

Description

technical field [0001] The invention relates to a medical surgical instrument, in particular to an Achilles tendon stapler used in percutaneous minimally invasive surgery. Background technique [0002] Achilles tendon rupture is usually the rupture of the Achilles tendon tissue caused by sports injuries or cutting or chopping. The traditional Achilles tendon suture operation is an open operation, which needs to reveal the normal part of the Achilles tendon, so that the suture can be fixed on the normal part of the Achilles tendon by bunnel, kessler, figure-of-eight suture and other common suture methods, so a long length of time is required. The incision requires the tendon sheath to be stripped, so the blood supply of the Achilles tendon tissue is severely damaged, and the incidence of complications is high. Complications include Achilles tendon re-rupture, skin necrosis, infection, and joint stiffness. [0003] Suturing the Achilles tendon with percutaneous minimally inva...
