Abstract

The invention provides a medical spinal cord cutting device and relates to a medical spinal cord processing device. The medical spinal cord cutting device includes: a scalpel with a C-shaped knife arm, the blade of the scalpel is formed in the depression of the knife arm and arranged along the arc of the knife arm, and the side wall of the spinal cord is placed on the knife arm. In the depression; and the holding mechanism includes a first mechanism, which is formed with a first depression; a second mechanism, which is formed with a second depression, and the second mechanism can be selectively engaged with or separated from the first mechanism, so that the first A concave part is fastened with the second concave part to form a hole-shaped part, the spinal cord and the knife arm are kept in the hole-shaped part; and the guide part is formed in the first mechanism or / and the second mechanism, and the scalpel is placed in the guide part, The guide part is used to guide the knife arm to separate from the foramen in the transverse direction of the spinal cord, so as to cut off the spinal cord. The end surface of the transected spinal cord is very neat, thus providing a very favorable guarantee for the subsequent fusion effect of the end of the spinal cord and the recovery of the 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...
