A treatment method for broken nails of medical orthopedic surgery plates

Abstract

The invention belongs to the technical field of medical equipment, and specifically discloses a medical orthopedic surgery steel plate broken nail treatment method. A nail removing device includes a rotary table, a drilling cutting module, a nail removing module and a lifting module. The rotary table is used for installing the drilling cutting module and the nail removing module. The drilling cutting module is used for drilling a long screw and cutting the long screw into several segments to facilitate the removal of the long screw one by one of segments. The nail removing module is used for taking out each segment of the long screw cut by the drilling cutting module one by one. The lifting module is used for realizing the up and down movement of the drilling and cutting module, and at thesame time, ensuring that rotating axes of the drilling cutting module and the nail removing module are in the same position during working. The medical orthopedic surgery steel plate broken nail treatment method adopts a method of segmentation removal of the long screw, and can avoid the breakage of the screw again, and the nail remoing effect is good.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a method for treating broken nails of a medical orthopedic surgical plate. Background technique [0002] With the development of orthopedic technology, screws and plates are usually used for internal fixation of fracture sites in clinical practice. When removing plates and screws, there are thread locking systems between plates and screws, and rust problems and other reasons. Screw breakage, wire slippage, and failure to remove the plate and take out the screws smoothly are problems that orthopedic surgeons cannot avoid, and clinicians often find it difficult. In order to remove the residual screw, the screw channel has to be reamed and slotted, which not only affects the blood supply of the tissue, but also reduces the bone mass and bone strength in the fixation area. Therefore, it is required to successfully remove the broken plate and screw without causing bone damage....

AI Technical Summary

Problems solved by technology

Although this technical solution can realize the removal of the broken nail, the technical solution can only carry out the nail removal operation on a part of the broken nail exposed outside the bone; The large torque may easily cause the screw to break inside the bone, making the process of removing the screw time-consuming and laborious
