Abstract

The invention provides a medical spinal cord cutting device, which relates to a medical spinal cord processing device. The medical spinal cord cutting device comprises a scalpel formed with a C-shapedknife arm, the knife edge of the scalpel is formed at the recess of the knife arm and arranged along the arc of the knife arm, and the side wall of the spinal cord is arranged in the recess of the knife arm; And a holding mechanism including a first mechanism formed with a first recess; A second mechanism formed with a second recess, the second mechanism selectively engaging or disengaging with the first mechanism so that the first recess is engaged with the second recess to form a hole, and the spinal cord and the knife arm are retained in the hole; And a guide portion formed in the first mechanism and / or the second mechanism, wherein the scalpel is disposed in the guide portion, and the guide portion is used for guiding the knife arm to be disengaged from the holding portion from the lateral direction of the spinal cord to cut the spinal cord. The spinal cord was transected and the end face was very neat, which provided a very favorable guarantee for the follow-up spinal cord end fusion effect and recovery of spinal cord injury.

Description

technical field [0001] The invention relates to a medical spinal cord processing device, in particular to a medical spinal cord cutting device. Background technique [0002] In patients with spinal cord injury, most patients have multi-segmental degeneration and necrosis of the spinal cord, which directly leads to the inability of the signal transmission from the cerebral cortex to cross the injured area. Therefore, in order to cure spinal cord injury, it is necessary to remove this necrotic spinal cord. According to According to the current medical research, the spinal cord is first sharply transected, that is, the spinal cord is cut off, the necrotic segment of the lesion is removed, and then the two fresh wounds at the end of the spinal cord are fused with spinal cord fusion agent, which can restore the conduction function of the spinal cord, so that The patient regained motor function. [0003] Acute transection of the spinal cord prior to spinal cord reconnection and f...
