Novel nail taking device for orthopedic department

Abstract

The invention discloses a novel nail taking device for the orthopedic department. The novel nail taking device comprises a base, a saddle arranged on the base, a nail taking cross rod oppositely arranged above the saddle and a nail taking device body which can move leftwards and rightwards and is arranged on the nail taking cross rod, wherein the nail taking device body comprises a main plate, a cutting sleeve capable of rotating and cutting a steel plate, a nail taking matching piece penetrating into the main plate and a nail taking assembly; a connection flange rotationally matched with the cutting sleeve is arranged at the lower part of the main plate; a first drive motor used for driving the cutting sleeve to rotate is arranged on one side of the main plate. The novel nail taking device is characterized in that the nail taking matching piece comprises a matching barrel, a first handle connected with the upper end of the matching barrel, a gripping claw arranged at the lower end of the matching barrel and a movable sleeve which can be arranged outside the matching barrel in a longitudinal moving manner and can open and close the gripping claw. With the adoption of the novel nail taking device, a screw rusted on the steel plate can be taken out smoothly, broken nails can also be taken out conveniently and quickly, and secondary harm to a patient is effectively avoided.

Description

technical field [0001] The invention belongs to the field of orthopedic medical devices, in particular to a novel 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 s...

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
