Fretsaw guiding device, spinal vertebral plate excision method and spinal nerve root anatomy method

Abstract

The invention belongs to the field of medical instruments, and relates to a fretsaw guiding device, a spinal vertebral plate excision method and a spinal nerve root anatomy method. In particular, thefretsaw guiding device is used for a spinal vertebral plate excision of a dead body of people or animals and / or a spine anatomy of a dead body of the people or animals; at least a part of the fretsawguiding device is formed into an L-shaped hard metal rod, the L-shaped hard metal rod is composed of a first end, a rod body and a second end, and the first end and the second end are fixedly connected with the rod body respectively and independently; the first end is set to be a rod-shaped or non-rod-shaped structure suitable to be grasped and operated by the hand; the second end is set to be anintegrated hook-shaped rod structure comprising an arc-shaped rod and a tip end, and the tip end is further provided with an opening so as to fix one end of a guided fretsaw. The fretsaw guiding device has the advantages that the construction is simple, the assembly is easy and operated easily, and not only can the labor intensity of an operator greatly reduced, but also the efficient and damage-free entire vertebral plate excision operation is achieved.

Description

technical field [0001] The application of the present invention belongs to the field of medical devices, and relates to a wire saw guiding device, a method for using the wire saw guiding device to perform a spinal laminectomy on a human or animal corpse, and using the wire saw guiding device to treat the spinal nerve roots of a human or animal corpse. Perform the dissection method. In particular, it relates to a wire saw guide for spinal laminectomy or dissection. Background technique [0002] In clinical practice, spinal surgery is one of the most difficult and risky operations in orthopedic surgery. The high risk is mainly reflected in the spinal cord in the spinal canal, the surrounding spinal nerve roots and the epidural dura mater of the spinal cord. If any part of the spinal cord is damaged due to improper operation, it will easily cause quadriplegia and diuretic dysfunction. Among the many potential causes of iatrogenic spinal nerve root injury, abnormal spinal nerv...

Problems solved by technology

However, using gun-like rongeurs to remove the laminae will take 1-2 days for the general experimenter to complete the laminectomy of the human spine. Tenosynovitis is very unfavorable for the development of a large number of anatomical experimental research projects

The danger of using an oscillating saw to remove the laminae is even more obvious. Due to the high-speed operation of the saw blade, the laminectomy can be too deep, resulting in damage to the spinal cord and spinal nerves in the spinal canal, and even the nerve root may be directly cut off by the saw blade. , so that the experiment fails

[0005] In short, in the existing human spinal nerve root variation research work, the available tools are limited in convenience, the intensity of physical labor is high, and the efficiency is low. Minimize the risk and pain of this "pitfall" in clinical spine surgery

Therefore, the limitations of existing technical means have affected the research progress in this direction
