Pair of gun type lifting pincers capable of effectively pressurizing fracture broken end

Abstract

The utility model discloses a pair of gun type lifting pincers capable of effectively pressurizing a fracture broken end. The pair of gun type lifting pincers comprises a handle, a gun barrel penetrating handle, a shifting piece which is arranged in handle; a compression spring is arranged between the shifting piece and the handle; the gun barrel is sleeved with a compression spring; a turning assembly is rotationally connected into the handle; when a trigger is pulled, the top of the trigger abuts against the lower end of the turning assembly. The upper end of the turning assembly abuts against the lower end of the shifting piece; the trigger drives the shifting piece to extrude the compression spring through the turning assembly; meanwhile, the shifting piece is propped against the top surface and the bottom surface of the gun barrel and drives the gun barrel to slide backwards; after being extruded, the shifting piece is changed into an inclined state from a vertical state; the tailend of an intramedullary nail is pulled by the pulling part to lift the fracture far section to the fracture near section; accurate pressurization of the fracture broken end is achieved, after pressurization operation is completed, the pressurization effect can be effectively maintained, the fracture end makes close contact with the fracture end after internal fixation, a stable and reliable mechanical conduction environment is provided for fracture healing, fracture healing is promoted, and delayed fracture healing and bone nonunion complications are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a gun-type lifting forceps which can effectively pressurize the broken ends of fractures. Background technique [0002] Intramedullary nailing has been widely used in extremity fractures and has achieved good clinical results. However, during the internal fixation of intramedullary nails, often due to improper operation, the fracture ends cannot be effectively pressurized, resulting in persistent separation, instability, and rotational movement of the fracture ends after internal fixation, which eventually leads to fractures that cannot be expected. Heal within a short period of time, and even complications such as nonunion and failure of internal fixation may occur. [0003] At present, in the operation of intramedullary nail fixation, the operation of pressurizing the broken end of the fracture usually adopts the method of knocking back the tail end of the intramed...

Problems solved by technology

Moreover, after knocking back, the compression effect of the fracture ends cannot be maintained, and the fracture ends are prone to separation again when the proximal locking nail is performed.
