A medical orthopedic surgery plate broken nail processing instrument

Abstract

The invention belongs to the technical field of medical apparatus and instruments, and in particular relates to a medical device for treating a steel plate and a broken screw for the orthopedic surgery. The medical device comprises a turntable, a drilling cutting module, a screw extracting module and a lifting module, wherein the turntable is used for mounting the drilling cutting module and the screw extracting module; the drilling cutting module is used for drilling the long screw, and cutting the long screw into a plurality of sections, so that the long screw can be taken out one section byone section; the screw extracting module is used for taking out each section of screw one by one for the long screw cut by the drilling cutting module; the lifting module is used for realizing the vertical movement of the drilling cutting module, meanwhile, when the drilling cutting module and the screw extracting module work, the rotation axes are at the same position. For the medical device, the method of taking out the long screw one section by one section is adopted, thus the secondary breakage of the screw can be avoided, and the screw extracting effect is good.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to an instrument 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 bon...

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
