Fracture end closed replacer

Abstract

A fracture end closed replacer comprises an n-shaped replacer body and a pressure handle. The pressure handle is in threaded connection with the replacer body, presses the replacer body according to the lever principle, and is provided with a fixing screw rod, a pressure fixing nut and a lateral pushing buckle adjustable in position. By the utilization of the lever action, a first transverse rod is made to generate enough longitudinal restoring force, and after being pressed to the proper position, the first transverse rod is locked through the pressure fixing nut. For lateral displacement fracture, the lateral pushing buckle on a longitudinal rod is adopted for lateral pushing restoration. The fracture end closed replacer can correct fracture end displacement caused by muscle traction in the axial traction of injured limbs, and cooperates with operations for placement of external supports or intramedullary nails. The fracture end closed replacer has the advantages of being simple in structure, convenient to operate, high in fixation force, good in fixing effect, capable of being sterilized at high temperature and capable of helping operators see the fracture ends under transmission in the operations.

Description

technical field [0001] The invention relates to a medical device, in particular to a fracture end closed reduction device for temporary fixation in fracture surgery. Background technique [0002] In the prior art, for orthopedic cases such as limb fractures, traction equipment is mainly used for fixation in the operation, but the existing traction fixture equipment has a complex structure, and when the traction equipment is axially traction, the force on the part of the fracture end is limited. The muscle attachment point is not well fixed, resulting in displacement caused by muscle stretching, so the fracture displacement cannot be effectively reset, which prolongs the operation time, increases the complexity of the operation, and easily causes the fracture to shift, making the operation unsuccessful. , used in conjunction with traction equipment during surgery, simple structure, convenient operation, good fixation effect, the closed reduction of the fracture end can be see...

Problems solved by technology

[0002] In the prior art, for orthopedic cases such as limb fractures, traction equipment is mainly used for fixation during the operation, but the existing traction fixture equipment has a complicated structure, and when the traction equipment is axially traction, the force on the part of the fracture end is limited. The muscle attachment point is not well fixed, resulting in displacement caused by muscle stretching, so the fracture displacement cannot be effectively reset, which prolongs the operation time, increases the complexity of the operation, and easily causes the fracture to shift, making the operation unsuccessful. , used together with traction equipment during operation, simple structure, convenient operation, good fixation effect, the closed reduction of the fracture end can be seen under the transmission during the operation, and it is very necessary to adjust the reduction force at any time under the current situation
