Pneumatic fastener gun for internal fracture fixation

Abstract

The invention provides a pneumatic fastener gun for internal fracture fixation. The pneumatic fastener gun comprises a gun body, a gun grip, a protective device, a fastener clamp device and a pneumatic device, a button is arranged at the head position at the joint of the gun grip and the gun body, and the tail of the button is embedded into the gun grip. The pneumatic fastener gun for internal fracture fixation is characterized in that the protective device comprises a protective cover and a protective cover connecting rod connected with the protective cover, the protective cover covers the head of a fastener passage device, a through hole is formed in the middle of the protective cover, and the tail end of the protective cover connecting rod contacts with the tail, embedded into the gun grip, of the button. The pneumatic fastener gun for internal fracture fixation has the advantages that the pneumatic fastener gun is simple and convenient to use and accurate when being used for fixing the fracture part and is capable of fixing the minimally invasive part effectively; the structure that the protective cover is matched with the button is equivalent to two triggering devices, a user who wants to shoot a fastener needs to enable a gun barrel to be aligned with the surface of the facture part by pressing while pressing the button, and accordingly, double protection effect and more safety in use are achieved to avoid misoperation during surgery.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a pneumatic nail gun for internal fixation of medical fractures. Background technique [0002] War trauma caused by natural disasters and high-tech wars in modern society has the characteristics of large trauma, dense personnel, and complex injuries, among which fractures account for a considerable proportion. If not treated in time, it can cause disability or death. [0003] Traditional internal and external fracture fixation devices and nail-plate systems, plaster / splint fixation, intramedullary nail, screw and plate fixation at home and abroad are cumbersome to use, have high requirements on the environment, surgical conditions, and surgical skills, and are inconvenient to observe and treat the wound surface. It cannot be applied to the first-line rapid treatment of batches of wounded in emergencies such as wartime, natural disasters and serious accidents, and has limitation...

Problems solved by technology

[0003] Traditional internal and external fracture fixation devices and nail-plate systems, plaster / splint fixation, intramedullary nail, screw and plate fixation at home and abroad are cumbersome to use, have high requirements on the environment, surgical conditions, and surgical skills, and are inconvenient to observe and treat the wound surface. It cannot be applied to the first-line rapid treatment of batches of wounded in emergencies such as wartime, natural disasters and serious accidents, and has limitations such as poor joint reduction and limited activities.

In addition, in the treatment of fractures, for comminuted fractures of the articular surface such as Colles fractures, olecranon fractures, humeral head fractures, ankle joint fractures, etc., the traditional fixation methods are not effective in fixing these types of fractures, and even cannot exert their full potential. due role
