An orthopedic bone nail processing device

Abstract

The invention relates to an orthopedic bone nail processing device, which is characterized in that: it includes a handheld shell, an input cone disk, an output cone disk, an intermediate cone disk, a speed regulating cone disk, a friction roller, and a cone head roller; the handheld shell is in the form of Hollow cylindrical shape, the handheld housing includes a dividing horizontal plate, an upper friction chamber, a lower transmission chamber, a bottom central shaft, a bottom runner, a driving bevel gear, an arc-shaped side hole, a sliding push rod, and a push rod bump. Fixed sliding rod; the speed regulating cone plate includes a fixed cone frame and a rotating cone cover that matches the fixed cone frame one by one; the friction roller corresponds to the rotating through hole one by one, and the friction roller includes Output gear and roller body; the cone-head roller includes a transmission barrel shell, a connecting rod, a cone-head plug block, and a compression spring. The orthopedic bone nail processing device of the present invention is used to rub the side or cone head of the bone nail to achieve surface cleaning.

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
