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

Abstract

The invention relates to a method for processing a side surface of a bone nail for the orthopedics department. The method is characterized in that a bone nail processing device for the orthopedics departments is used, wherein the bone nail processing device for the orthopedics department comprises a handheld housing, an input conical disc, an output conical disc, a middle conical disc, a speed regulating conical disc, a friction roller and a conical head roller. The method for processing the side surface of the bone nail for the orthopedics department comprises the following steps of: step 1,inserting the bone nail; step 2, rubbing the bone nail; and step 3, regulating rotation speed. The method for processing the side surface of the bone nail for the orthopedics department is simple andquick to operate; the bone nail is inserted into a friction upper cavity from a bone nail inlet, so that the side surface of the bone nail is in contact with a roller body, the handheld housing is pushed to move for driving the roller body to rotate, the side surface of the bone nail is rubbed to remove burrs; and a conical head insertion block can be pulled to regulate a transmission proportion of the speed regulating conical disc, so that rotation speed regulation of the roller body is realized, and therefore, the friction processing effect for the side surface of the bone nail is regulated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method for treating the side of a bone nail used in 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 ...
