Abstract

The invention discloses a simple multipurpose rat femur outside fixing support which comprises a plastic outside fixing support clamping plate, mounting screws and Kirschner wires. Mounting positioning holes are formed in the lateral side of the plastic outside fixing support clamping plate, the Kirschner wires are mounted in the mounting positioning holes, screw mounting holes are formed above the plastic outer fixing support clamping plate, each mounting screw is mounted inside the corresponding screw mounting hole, and each Kirschner wire is a threaded Kirschner wire of 1.2mm in diameter. The invention relates to the technical field of animal experiments and damage repair. Cost of the outside fixing support is saved while weight of the same is reduced, and the outside fixing support issimple in operation, economical, practical and firm in fixing; due to grooves designed in the clamping plate, needs of various models for bone defect, bone fracture and bone ununion can be met, and fixing needs of rat femur fracture, ununion and defect experiments are met, so that the outside fixing support has the advantages of being simple, light, economical, practical and multipurpose.

Description

technical field [0001] The invention relates to the technical fields of animal experimentation and damage repair, in particular to a simple multipurpose rat femur external fixation bracket. Background technique [0002] Rats are widely used in animal experiments due to their low cost of breeding and easy availability of antibodies on the market. Many experiments on fractures, nonunions and bone defects have also been performed on rats, but due to the small size of rat bones, the fixation of the bones is difficult. Therefore, finding an ideal fixing method has always been the goal pursued by scholars. Currently, rat bone fixation methods mainly include intramedullary nails, bone plates, and external fixation brackets. Intramedullary nail fixation is simple and easy to use, and the cost of use is low, but its use is limited because it cannot effectively control the shortening, separation and rotation of the fracture end. The bone plate fixation is firm, but the soft tissue ...
