Elastic bending tool for femoral intramedullary nails

Abstract

The invention relates to an elastic bending tool for femoral intramedullary nails, comprising a base; a presser block is arranged above a bending station; a forming surface is provided with a pressergroove; left and right support plates that are rotatable are arranged between two mounting side plates; the left end of the left support plate is rotationally connected with the two mounting side plates through pins; a left spring is arranged blow the right end of the left support plate; the right end of the right support plate is rotationally connected with the mounting side plates via pins; a right spring is arranged below the left end of the right support plate; a retaining plate is arranged in the middle of each mounting side plate; the left support plate is provided with a left support wheel; a right support wheel is arranged on the right support plate; the left of the left support plate is provided with a clamping device to clamp the proximal end of an intramedullary nail; during operation, an intramedullary nail to be bent is placed on the clamping device, the left support wheel and the right support wheel; the two support plates may form obtuse structure when the intramedullarynail is under pressure; the two support wheels can be rotated and spread such that smooth transitional forming is achieved for the intramedullary nail.

Description

Technical field [0001] The invention relates to the medical field, in particular to an elastic femoral intramedullary nail bending tool. Background technique [0002] In the process of making intramedullary nails, they will be bent to a certain degree to adapt to the physiological curvature of the corresponding bones of the human body; in the current intramedullary nail bending process, the bends are concentrated at a certain point, resulting in The stress is relatively concentrated, and the bending effect and bending quality are relatively low. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an elastic femoral intramedullary nail bending tool. [0004] The technical solution adopted by the present invention to solve its technical problem is: an elastic femoral intramedullary nail bending tool, including a base, the middle of the base has a bending station, and the upper part ...
