Rapid positioning auxiliary drilling device for carpal bone and forearm far-end surgical operation

Abstract

The invention discloses a rapid positioning auxiliary drilling device for carpal bone and forearm far-end surgical operation. The rapid positioning auxiliary drilling device comprises a supporting column, an adjusting cylinder, an adjusting knob and a fixing ring, wherein a supporting rod is arranged on one side wall of the supporting column, a supporting plate is arranged at one end away from thesupporting column, of the supporting rod, a gasket is bonded to the upper end of the supporting plate, and a lead screw is welded to the top end of the supporting column. The rapid positioning auxiliary drilling device has the beneficial effects that by arranging the adjusting knob, the lead screw, the adjusting cylinder and a connecting rod, the height of the fixing ring can be conveniently adjusted, traditional tedious bolt adjustment is avoided, the height of the fixing ring can be adjusted more flexibly, and the rapid positioning requirement of an ulna or radius operation is met. By arranging a sliding sleeve, an adjusting rod, a gear, an adjusting groove, a tooth groove, a locking bolt, an opening, a positioning window, a transparent glass plate, a sleeve positioning hole and an adjusting long hole, accurate positioning of the ulna or radius part of the wrist of the patient can be realized when the wrist of the patient is reliably fixed, and the subsequent operation efficiency isconveniently improved.

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...

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
