Frame-type pressurizing multipurpose guider

Abstract

Disclosed is a frame-type pressurizing multipurpose guider. The frame-type pressurizing multipurpose guider is characterized by being composed of a main frame (1) and a guide barrel (2), a positioner (3) is arranged at one end of the main frame, triangular three toes (4) are arranged at the tail end of the positioner, a nut (5) is arranged at the other end of the main frame, an external thread (6) of the guide barrel is matched with the nut, a guide hole (7) is arranged in the guide barrel, and an inner hexagon groove (9) is arranged at the tail of the guide barrel. The frame-type pressurizing multipurpose guider has the advantages that according to knowledge of human anatomy, fractures of irregular bones of a human body are multiple fractures, especially fractures of scaphoid, calcaneus, astragali and the like; when fixing in the guide barrel is needed, a guide needle can be accurately implanted at one step, so that artificial osteoporosis caused by repeated implanting of the guide needle can be avoided to realize stable fixing of a screw. The frame-type pressurizing multipurpose guider is convenient for fracture pressurizing, pressurizing can be conveniently performed by the guider when the scaphoid fractures, separates, shifts, closes and restores for the convenience of early healing of fracture, and the frame-type pressurizing multipurpose guide is suitable for implanting of the guide needle of the guide barrel for various fractures of the irregular bones of the human body.

Description

technical field [0001] The invention relates to the field of medical devices, specifically, it is a special device used in the closure and reduction of irregular bone fractures in clinical orthopedics and the internal fixation of guide cylinders. It is used for fracture closed reduction and pressurization, and the guide cylinder and guide pin can be placed smoothly according to the expected requirements, so as to facilitate fracture reduction, pressurization, and the guide cylinder can put the guide pin into the expected position. Background technique [0002] Minimally invasive osteosynthesis and internal fixation has become a popular trend. The principles of fracture treatment proposed by the International Organization of Internal Fixation (AO) in the early days of its establishment have been replaced by the concept of BO (biological osteosynthesis) after decades of research and application. The core of BO is to use reasonable reduction techniques to avoid exposing the fr...

AI Technical Summary

Problems solved by technology

It is easy to cause artificial osteoporosis when it is placed repeatedly, which is not conducive to the fixation of the guide cylinder, thus affecting the firmness of the internal fixation screw
