Problems solved by technology

[0003] However, the ulna or radius surgical positioning device mainly uses a finger fixer to fix the patient's arm, which leads to the inability to quickly and accurately locate the ulna or radius at the patient's wrist, reducing the efficiency of the operation. Secondly, the finger fixer on the device mainly The height adjustment is achieved through the cooperation of bolts and screw holes, which makes the height adjustment of the finger holder not flexible and convenient enough to meet the needs of rapid positioning in ulna or radius surgery. Moreover, the patient's elbow is in a suspended state when the device is in use. As a result, the patient's comfort during the operation is poor, so a new type of rapid positioning auxiliary drilling device is urgently needed to solve the existing problems

Abstract

The invention discloses a rapid positioning auxiliary drilling device for wrist bone and forearm distal surgery, which includes a support column, an adjustment cylinder, an adjustment knob and a fixing ring. One end of the supporting column is provided with a supporting plate, the upper end of the supporting plate is bonded with a liner, and the top end of the supporting column is welded with a screw rod. The beneficial effect is that by setting the adjustment knob, the screw rod, the adjustment cylinder and the connecting rod, the convenient adjustment of the height of the fixing ring can be realized, which avoids the tedious adjustment of the traditional bolts, makes the height adjustment of the fixing ring more flexible, and meets the needs of ulnar or radial surgery. Rapid positioning requirements; by setting sliding sleeves, adjusting rods, gears, adjusting grooves, tooth grooves, locking bolts, openings, positioning windows, transparent glass plates, sleeve positioning holes and long adjustment holes, it is possible to achieve reliable fixation of the patient's wrist. At the same time, the precise positioning of the ulna or radius at the patient's wrist can be achieved, which is convenient for improving the efficiency of subsequent operations.

Description

technical field [0001] The invention relates to the technical field of ulna or radius surgical aids, in particular to a rapid positioning auxiliary drilling device for carpal and forearm distal surgery. Background technique [0002] The ulna or radius is the stable bone of the forearm. It is the inner and longer bone of the two forearm bones. It is divided into two ends. Wherein, when the patient's ulna or radius is operated on, it is often necessary to perform positioning drilling on the ulna or radius of the patient's wrist. [0003] However, the ulna or radius surgical positioning device mainly uses a finger fixer to fix the patient's arm, which leads to the inability to quickly and accurately locate the ulna or radius at the patient's wrist, reducing the efficiency of the operation. Secondly, the finger fixer on the device mainly The height adjustment is achieved through the cooperation of bolts and screw holes, which makes the height adjustment of the finger holder not...
