Universal traction device for manufacturing ischiadic nerve tension damage model and applications of universal traction device

Abstract

The invention relates to a universal traction device for manufacturing an ischiadic nerve tension damage model and applications of the universal traction device. The universal traction device comprises a connecting bottom board as well as a traction module, a distortionless force measurement module, a guide module, a fixed forceps holder module, a movable forceps holder module and a computer which are arranged on the connecting bottom board, wherein one side of the distortionless force measurement module is connected with the traction module, the other side of the distortionless force measurement module is connected with the guide module, the fixed forceps holder module and the movable forceps holder module are oppositely arranged, the movable forceps holder module is arranged on the guide module, and the distortionless force measurement module and the traction module are connected with the computer. When the universal traction device is used for manufacturing the ischiadic nerve tension damage model, through the connection control of the computer, the accurate traction force and traction length as well as the corresponding relation between the traction force and the traction length can be obtained, meanwhile, the extension length and position of the forceps holder can be adjusted, and the rough method of the traditional experimental device in the past is changed, so that the experimental process is convenient and rapid as well as efficient, and the experimental result is reliable.

Description

technical field [0001] The invention relates to a universal pulling device for making a model of sciatic nerve tension injury and an application thereof, which belongs to the technical field of medical experimental equipment. Background technique [0002] Peripheral nerve injury is one of the common severe traumatic diseases clinically, and its recovery process is slow, and the recovery effect is often unsatisfactory. Determining the degree of nerve injury and the ability to repair and regenerate is an important prerequisite for improving the clinical treatment effect. The experimentally induced rabbit sciatic nerve tension injury model is one of the commonly used research methods for the degree of nerve injury and the ability to repair and regenerate. The production of the rabbit sciatic nerve tension injury model It is necessary to bind the anesthetized rabbit to its side, cut the skin behind the thigh of the treated side hindlimb, and perform blunt separation along the mu...

Problems solved by technology

[0004] However, there is currently no suitable device to achieve the above functions

Although the existing nerve retractors used in the excision of the nucleus pulposus for lumbar disc herniation can quantify the strength of nerve stretching, they cannot quantitatively stretch the sciatic nerve at the test segment with an accurate length, and the nerve retractors cannot conveniently adjust the stretching speed And real-time acquisition of the corresponding relationship between pulling force and pulling length
