An orthopedic bone nail processing device

Abstract

The invention relates to a bone nail processing device for the orthopedics department. The bone nail processing device is characterized by comprising a handheld housing, an input cone disc, an outputcone disc, a middle cone disc, a speed regulation cone disc, friction rollers and a conehead roller, wherein the handheld housing is in a shape of a hollow cylinder, and the handheld housing comprisesa separation transverse plate, a friction upper cavity, a driving lower cavity, a bottom middle shaft, a bottom rotating wheel, a driving bevel gear, an arc-shaped side hole, a sliding push rod, a push rod bulge and a fixed sliding rod; the speed regulation cone disc comprises fixed cone frames and rotary cone covers which are matched with the fixed cone frames one by one; the friction rollers are in one-to-one correspondence to rotating through holes, and the friction rollers include output gears and roller bodies; and the conehead roller comprises a driving cylindrical shell, a connecting inserted rod, a conehead inserted block and a compression spring. The bone nail processing device for the orthopedics department is used for performing friction treatment on the side surfaces or coneheads of bone nails, so that a surface cleaning effect is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone nail processing device for orthopedics. Background technique [0002] Bone nail is a structure used for internal fixation in orthopedic surgery. Most of them have a helical rod body for screwing into the bone and an end for matching. The end has a hexagonal groove or grooves of other shapes, and then matches with the electric drill. [0003] Bone nails are usually used in fields such as connecting broken bones and correcting deformities. Generally speaking, even though bone nails are used to complete the bone connection, due to the limited hardness and rigidity of existing materials, bone nails are prone to fall off, breakage, and deformation. The removal of the bone nails and the analysis of the deformation of the bone nails during the removal are conducive to further research on various operations, such as structural reinforcement for parts with large deformati...

Problems solved by technology

Generally speaking, even though bone nails are used to complete the bone connection, due to the limited hardness and rigidity of existing materials, bone nails are prone to fall off, breakage, and deformation. The removal of bone nails, analyzing the deformation of the bone nails during removal is conducive to further research on various operations, such as structural reinforcement for parts with large deformations, etc.

[0004] However, the bone nails taken out from the human body will inevitably carry bone or other tissues when they are removed, so it is necessary to design a device for cleaning the surface of the bone nails
