Problems solved by technology

[0002] Achilles tendon rupture is usually the rupture of the Achilles tendon tissue caused by sports injuries or knife wounds. The traditional Achilles tendon suture operation is an open operation, and the exposed Achilles tendon needs to be sutured to fix the suture on the Achilles tendon. However, it has the following disadvantages: the incision is large, the operation time is long, and the nerve is easily damaged. In addition, the tendon sheath needs to be stripped during the operation, so the blood supply of the Achilles tendon tissue is severely damaged, and the skin necrosis and infection of the incision are prone to occur. and non-union complications
