Skin-outside fixation locker for fracture

Abstract

An skin-outside fixation locker for a fracture is characterized by comprising an emergency temporary fixer and a minimally invasive surgery fixer. The emergency temporary fixer comprises a skin-outside fixation main plate, a threaded fixation needle and a threaded fixation needle nut; the minimally invasive surgery fixer comprises a skin-outside fixation main plate, a locking screw and a protective pad layer which is laid between a skin-outside locking main plate and the skin in a padding mode during a surgery. According to the skin-outside fixation locker, the defects of locking steel plate internal fixation and intramedullary nail fixation can be overcome, the fixation locking surgery is beneficial for postoperative rehabilitation and fracture healing, the skin-outside fixation locker is placed outside the skin and can be removed at an outpatient clinic after the fracture is healed without being in a hospital, treatment seeking of a patient is facilitated, the medical cost is effectively reduced, and the locker is particularly suitable for being used for emergency rescue in a major natural disaster or war time.

Description

technical field [0001] The invention relates to an orthopedic medical device, in particular to a fracture external fixation and locking device. Background technique [0002] For limb fracture fixation surgery, internal fixation with plate screws, external fixation brackets and intramedullary nails are commonly used at present. When using plate and screw internal fixation, in order to fully expose the fracture end and place the plate, it is often necessary to peel off the soft tissue of the fracture end in a large area, the surgical trauma is relatively large, and the pressure plate close to the bone surface will cause ischemia of the periosteum under the plate. Increased risk of fracture nonunion and infection. With the promotion of the concept of minimally invasive surgery and the emergence of locking plates, the technique of percutaneously inserting locking plates through small incisions for internal fixation of fractures has become more and more widely used clinically. ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention aims at the defects of the existing steel plate screw internal fixation, intramedullary nail internal fixation and external fixation bracket, especially the technical problem of the lack of temporary fast fixation devices for fractures in emergency rescue, and provides a It is a device that performs rapid rescue at the emergency scene first, and can continue to complete the surgical fixation after the wounded is transferred to the operating room
