Fracture reverser

Abstract

A fracture repositor belongs to a technical field of surgical medical appliance used for providing a fracture repository which carries out draught on a wounded limb under a closed situation and uses an ejector pin to carry out ejection, lifting and pushing, reposition and temporary fixing, and can be arranged in an inner fixing device under a minimal invasion situation with the advantages of few bleeding, short operation time and fast concrescence. A rack is arranged at one side of a guide rod and the guide rod is provided with two sliding guides. Each sliding guide is provided with a gear engaged with the rack and is fixed with a single-direction limiting mechanism provided with a tow rod and a gear. One end of a gear shaft is provided with a rotary handle or a hexagon head. The tow rod is provided with a clamping mechanism and the guide rod between the two sliding guides is provided with two to six fixing rods. An adjustable mechanism for mutual positions is arranged between the fixing rods and the guide rod. The fixing rods are provided with the clamping mechanism fixing a Kirschner steel needle or the ejector pin. The invention can be arranged in the inner fixing device under the minimal invasion situation only to beat into a Kirschner steel pin arranging hole with an aiguille, thus having the advantages of small damage to a patient, high fracture concrescence rate, short operation time and low operation cost.

Description

technical field [0001] The invention relates to a fracture reducer, which belongs to the technical field of surgical medical instruments. Background technique [0002] At present, when performing surgery on the displaced fracture site and needing to implant an internal fixator, procedures such as surgical incision, traction, and manual reconstruction of the fracture are often required. The disadvantages are that the operation time is long and the work intensity of the medical staff big. In addition, using the above-mentioned method to treat fractures will cause great trauma to the fracture site, a lot of bleeding, and easy infection, which is not conducive to fracture healing, and the medical expenses borne by the patient are also relatively high. Contents of the invention [0003] The purpose of the present invention is to provide a fracture reducer, which can be used to pull the affected limb under the closed condition and use the thimble pin to push, pry, reset, and te...

[0002] At present, when performing surgery on the displaced fracture site and needing to implant an internal fixator, procedures such as surgical incision, traction, and manual reconstruction of the fracture are often required. The disadvantages are that the operation time is long and the work intensity of the medical staff Big

In addition, using the above method to treat fractures will cause large trauma to the fracture site, more bleeding, and easy infection, which is not conducive to fracture healing, and the medical expenses borne by the patient are also relatively high.
