Orthopedics nail withdrawal equipment having clamping function

Abstract

The invention discloses orthopedics nail withdrawal equipment having a clamping function. The equipment comprises a base plate, wherein vertical plates are fixedly connected to both ends of the base plate; a top plate is fixedly connected to the tops of both the vertical plates; a placing groove is defined in the middle of the upper side of the base plate; a threaded rod is rotatably connected tothe middle of the top plate; and a supporting pillar is arranged at the lower side of the threaded rod. The orthopedics nail withdrawal equipment provided by the invention has the beneficial effects that magnetism, which is same to a magnetic pole, is generated as an electromagnet is charged with a current, so that the magnetic pole, which is repelled, moves downwards in a mode of being away fromthe electromagnet under repulsive force, so that a mounting pillar is driven to move downwards and the two clamping plates are squeezed by virtue of a connecting rod which is driven by the mounting pillar, and subsequently, the two clamping plates are moved apart, and a distance between the two clamping plates is widened; then, a clamping plate drops, and the head of a nail enters a region betweenthe two clamping plates; and the electromagnet is charged by a reverse current, so that magnetism, which is opposite to the magnetic pole, is generated, and subsequently, the magnetic pole is moved upwards and the mounting pillar, which is driven by the magnetic pole, is moved upwards.

Description

technical field [0001] The invention relates to the technical field of orthopedics, in particular to a nail-removing device for orthopedics with a clamping function. Background technique [0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. With the changes of the times and society, the spectrum of orthopedic injuries has undergone significant changes. For example, bone and joint tuberculosis, osteomyelitis, polio and other diseases have decreased significantly, and trauma caused by traffic accidents has increased significantly. Changes in the spectrum of orthopedic injuries require orthopedics to keep pace with the times. [0003] Orthopedics is also called orthopedics. It is a profession or discipline of medicine, specializing in the study of the an...

Problems solved by technology

In the process of removing the bone plate after the internal fixation operation, the screws need to be removed. Due to the limitation of the installation position, it is very difficult for medical personnel to operate, and the screws are often broken due to different reasons, and it is difficult to pass the screws through a screwdriver, etc. The tool is screwed out, and the process of removing the nail is time-consuming and laborious, and it is easy to increase the trauma and operation time, which once again brings a lot of unnecessary pain to the patient
