Embodiment Construction

[0032] like Figure 1 to Figure 8 Shown is a method for treating scaphoid fractures and an auxiliary treatment device, a method for treating scaphoid fractures, comprising the following steps:

[0033] (1) The patient is placed in the supine position, nerve block anesthesia or general anesthesia, the upper limbs are abducted on the operating table, the wrist joint is fixed in the dorsiflexion position using the wrist fixation seat 1, and the trapezium-scaphoid tubercle is determined and marked ;

[0034] (2) Assemble the sterilized auxiliary treatment device, and connect the auxiliary treatment device to the wrist holder 1;

[0035] (3) Make a 1cm transverse incision at the skin mark, and separate the subcutaneous tissue until the scaphoid-trapezoid joint space;

[0036] (4) Insert the bone hook into the gap to hook the navicular bone and pry it to the radial side. At this time, rotate the sharp tip part of the guide sleeve 8 in the auxiliary treatment device to penetrate th...

Abstract

The present invention provides a method and device for treating scaphoid fracture in the medical technology field, comprising the following steps: fixing the wrist joint in dorsiflexion position with a wrist fixation seat, determining trapezoid-scaphoid tubercle and marking ; Connect the sterilized auxiliary treatment device to the wrist fixation seat; make a 1cm transverse incision at the skin mark, separate the subcutaneous tissue until the scaphoid joint space; The guide sleeve pierces the surface of the distal pole of the scaphoid to lock the device; adjust the angle of the guide sleeve; use fluoroscopy to determine the direction of the sleeve, and confirm that the guide pin is inserted correctly; drive the anti-rotation Kirschner wire along the guide pin, remove Auxiliary treatment device; drill the guide pin into the distal end of the radius, and use a hollow drill to drill through the guide pin; double-ended compression screws pass through the guide pin and screw into the scaphoid; confirm the screw position again by fluoroscopy, and pull out the anti-rotation Kirschner wire , stop bleeding and suture the wound; the invention ensures accurate needle insertion and reduces the number of times of needle insertion and perspective.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a method and device for treating scaphoid fractures. Background technique [0002] Scaphoid fractures are the most common carpal fractures, accounting for 60%-70% of carpal fractures, and most of them are young adults, and most of them are low-energy sports injuries. Due to its special position, anatomical structure and blood supply, scaphoid fractures If not handled properly, the necrosis rate is higher than other fractures. [0003] The treatment of non-displaced scaphoid fractures mainly includes conservative plaster fixation and surgical treatment. Conservative treatment requires up to three months of plaster fixation, which seriously affects the quality of life of patients. It is difficult to engage in even light activities. Unacceptable, if not handled properly, there is a 5%-20% possibility of non-union; surgical treatment is divided into incision fixation and minimally ...
