Auxiliary device for treating calcaneal fracture under arthroscope and operation methods

Abstract

The invention provides an auxiliary device for treating calcaneal fracture under an arthroscope. The auxiliary device includes a simple retractor, a first auxiliary mechanism and a second auxiliary mechanism. The first auxiliary mechanism includes a first guide needle, a first inner core and a Y-shaped sleeve pipe, and the second auxiliary mechanism includes a second guide needle, a second inner core and a positioning sleeve pipe. The invention further provides positioning operation methods of the first auxiliary mechanism and the second auxiliary mechanism. By using the operation method, theY-shaped sleeve pipe and the positioning sleeve pipe can be smoothly fixed, the operation of the subtalar arthroscope and a manipulator can be conveniently realized by using the Y-shaped sleeve pipe and the positioning sleeve pipe, and then the smooth operation of a surgery is facilitated; and meanwhile, the Y-shaped sleeve pipe and the positioning sleeve pipe can prevent soft tissue from being damaged when the subtalar arthroscope and the manipulator descend repeatedly, and then the surgical effect can be guaranteed.

Description

technical field [0001] The invention relates to an auxiliary device for arthroscopic treatment of calcaneal fractures and an operating method thereof. Background technique [0002] Calcaneal fracture is the most common tarsal fracture. Calcaneal fracture can cause the height of calcaneus to decrease and the arch of the foot to collapse, affecting the shape and mechanical stability of calcaneus. Intra-articular fracture can cause traumatic arthritis of subtalar joint. Complications such as tendon entrapment and difficulty wearing shoes caused by widening of the calcaneus lead to foot dysfunction. At present, open reduction and internal fixation has become the most common and effective method for the treatment of displaced calcaneal fractures, but there are complications such as postoperative incision soft tissue nonunion, exposure of implants, postoperative infection, osteomyelitis, etc., which affect the surgical treatment effect . When subtalar arthroscopy is used to trea...

AI Technical Summary

Problems solved by technology

At present, open reduction and internal fixation has become the most common and effective method for the treatment of displaced calcaneal fractures, but there are complications such as postoperative incision soft tissue nonunion, exposure of implants, postoperative infection, osteomyelitis, etc., which affect the surgical treatment effect

When subtalar arthroscopy is used to treat calcaneal fractures, because the subtalar space is narrow and difficult to operate, clinical application has not been promoted, and repeated implantation of subtalar arthroscopes is likely to cause soft tissue damage and increase the chance of postoperative infection
