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 fur

Abstract

The invention relates to a treatment method of a bone nail conehead for the orthopedics department. A treatment device of the bone nail conehead for the orthopedics department is adopted. The treatment device of the bone nail conehead for the orthopedics department comprises a handheld shell, an input cone disc, an output cone disc, a middle cone disc, a speed-regulating cone disc, a friction roller wheel and a conehead roller. The treatment method of the bone nail conehead for the orthopedics department includes the following steps that 1, a bone nail is inserted; 2, the bone nail is rubbed;3, the rotating speed is regulated. The treatment method of the bone nail conehead for the orthopedics department is easy and rapid to operate, the bone nail is inserted into a friction upper cavity from a bone nail inlet, the lower end of the bone nail presses a conehead inserting block, a connecting inserting rod and a transmission barrel shell downwards, and the transmission barrel shell and aninput gear are in transmission connection; then the handheld shell is pushed to move, the conehead inserting block can be driven to rotate, and the bone nail conehead is rubbed; the transmission ratio of the speed-regulating cone disc can be regulated by thumbing the conehead inserting block, the rotating speed of the conehead inserting block is regulated, and the friction treatment effect on thebone nail conehead is regulated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method for processing a cone head 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 p...
