Problems solved by technology

However, long-term compression of plaster or external fixation of the brace can cause blood circulation disturbance in the lower leg and affect the blood supply of the Achilles tendon. One is the pain of extreme discomfort caused by long-term plaster or external fixation of the brace to oppress the calf

Embodiment Construction

[0016] like figure 1 As shown, the present invention provides a minimally invasive Achilles tendon fixation stapler, including a calcaneus positioning group and an Achilles tendon positioning group, both of which include a U-shaped ring 2, a main connecting rod 3, a universal fixing nut 1 and a fixing The needle 4 and the fixed needle 4 are fixedly connected to the U-shaped ring 2 through the universal fixed nut 1; the U-shaped rings 2 in the same positioning group are connected by the main connecting rod 3 under the action of the universal fixed nut 1, different positioning The groups are fixedly connected by auxiliary connecting rods 6 .

[0017] Four U-shaped rings, four bone fixation pins, four Achilles tendon fixation pins, fourteen universal fixing nuts, four needle arm nuts, four needle arm nuts, and five connecting rods are required for use. .

[0018] After anesthesia, the affected area was routinely disinfected and draped, and the broken Achilles tendon was checked...

Abstract

The invention belongs to an instrument for wound anastomosis and particularly discloses a minimal invasion heel tendon fixing anastomat which comprises a calcaneal bone positioning group and a heel tendon positioning group, wherein each of the two positioning groups comprises U-shaped rings, a main connecting rod, a universal fixing screw cap and a fixing needle; the fixing needle is fixedly connected with the U-shaped ring through the universal fixing screw cap; U-shaped rings in the same positioning group are connected by the main connecting rod under the action of the universal fixing screw cap; and different positioning groups are fixedly connected by an auxiliary connecting rod. With the adoption of the minimal invasion heel tendon fixing anastomat, the connection stability of the broken end of the heel tendon wound is improved, the blood supply to the heel tendon is not damaged, and the infection of suture line and rejection are avoided.

Description

technical field [0001] The invention belongs to medical instruments for anastomosis of wounds, in particular to a minimally invasive Achilles tendon fixation stapler. Background technique [0002] Acute Achilles tendon rupture is a common labor operation, military training, and sports injury. The common site of rupture is 2-6 cm from the insertion of the calcaneal bone. According to reports, Achilles tendon rupture ranks third among tendon ruptures. The repair of Achilles tendon rupture is often due to tendon adhesion, scar repair, poor healing, infection, and rejection of sutures, etc., so that the Achilles tendon healing cannot meet the ideal requirements. Its occurrence is related to the treatment method and the relative scarcity of the local blood supply of the Achilles tendon. The blood supply of the Achilles tendon is mainly provided by the mesotendinosum. Acute Achilles tendon rupture can be divided into closed and open. The common injury mechanism of closed Achille...
