Nail removal device for orthopedics

Abstract

The invention discloses a nail removal device for an orthopedics department. The device comprises a base, a supporting table disposed on the base, a nail removal horizontal rod which is disposed oppositely above the supporting table as well as a nail removal device body which can be moved horizontally and disposed on the nail removal horizontal rod, wherein the nail removal device body comprises a main plate, a cutting sleeve which can be rotated to cut a steel plate, a nail removable matching part which passes through the main plate as well as a nail removal assembly; and a connecting flange which forms rotary fitting with the cutting sleeve is disposed on the lower part of the main plate, and a first drive motor which can drive rotation of the cutting sleeve is disposed on a side part of the main plate. The device is characterized in that the nail removal matching part comprises a matching cylinder, a first holding handle connected to the upper end of the matching cylinder, a grasping claw disposed on the lower end of the matching cylinder as well as a movable sleeve which can sleeve the matching cylinder in a vertically movable manner and can then open or close the grasping claw. The device disclosed by the invention has the advantages that a screw which is combined with a steel plate due to rusting can be taken out smoothly; a broken nail can be also taken out easily and quickly; and second-time harms to a patient can be effectively avoided.

Description

technical field [0001] The invention belongs to the field of orthopedic medical devices, in particular to a nail removal device for orthopedics. 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 su...

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
