Orthopedic Nail Removal Equipment

Abstract

The invention discloses practical nail removing equipment for the department of orthopedics. The practical nail removing equipment comprises a nail removing bracket, a positioning bracket connected with the nail removing bracket, a nail removing base fixedly connected to the upper surface of the nail removing bracket and a nail remover movably arranged on the positioning bracket, wherein the nail remover comprises a main board, a cutting sleeve capable of rotating to cut a steel plate, a nail removing mating part penetrating in the main board as well as a nail removing assembly; a connecting flange capable of being in rotating fit with the cutting sleeve is arranged at the lower part of the main board, and a first driving motor capable of being used for driving the cutting sleeve to rotate is arranged at the side part of the main board. The practical nail removing equipment is characterized in that the nail removing mating part comprises a mating cylinder, a first holding handle connected to the upper end of the mating cylinder, a grabbling claw arranged at the lower end of the mating cylinder and a movable sleeve capable of being arranged outside the mating cylinder in a vertically moving and sleeving manner to open and close the grabbing claw. The nail corroded together with the steel plate can be removed smoothly, a broken nail is also taken out conveniently and rapidly, and secondary harm to a patient is avoided effectively.

Description

technical field [0001] The invention belongs to the field of orthopedic medical devices, in particular to an orthopedic nail removal device. Background technique [0002] A fracture is a break in the integrity and continuity of a bone. At present, for patients with obvious displacement and needing open reduction and internal fixation, the bone fragments at the fracture site are usually re-reset and fixed with steel plates and bone screws, so that the dislocated bone fragments are tightly connected again under the action of the plate screw system Together, after a long period of postoperative growth, the broken bone fragments grow new calluses and heal together again. It is often necessary to remove the internal fixation within 1-2 years after endosteosynthesis to avoid rejection, etc. However, due to the long healing time, the steel nail will shift slightly, or be welded together with the steel plate, making it difficult to remove; And under the influence of factors such a...

AI Technical Summary

Problems solved by technology

It is often necessary to remove the internal fixation within 1-2 years after endosteosynthesis to avoid rejection, etc. However, due to the long healing time, the steel nail will shift slightly, or be welded together with the steel plate, making it difficult to remove; And under the influence of accidents, improper operation and other factors, it is very easy for the screw to break, so that it is necessary to increase the slotting area when removing the nail, causing secondary damage to the patient
