Technical Field
The invention relates to the field of medical instruments, in particular to a surgical instrument guide, an intervertebral foramen abrasive drill and an intervertebral foramen forming surgical device.
Background
The minimally invasive technology of the intervertebral foramen mirror spine represents a brand new concept of minimally invasive spine surgery, and can develop the herniated disc, the foramen forming and the annulus repair of all segments from cervical vertebra to lumbo 5 sacrum 1. The satisfactory curative effect of the operation can reach 75-90 percent. Because of its many advantages, the world spinal minimally invasive surgery field has now recognized the dominant role of the foramen mirror in this field.
Smooth establishment of the milling and drilling channel of the intervertebral foramen mirror is the key to successful operation, and intervertebral foramen forming is the most key step for establishing the channel. The inter-foraminal formation is to grind off a part of the articular process by using an inter-foraminal mirror grinding drill, clear away peripheral obstacles, enlarge inter-foraminal space and allow a grinding drill channel to enter so as to reach the position of the protruding nucleus pulposus. The existing intervertebral foramen forming process has the following problems:
1. the position of the intervertebral foramen mirror grinding drill is difficult to control in the bone grinding process, offset is easy to occur, and meanwhile, the working range of the intervertebral pore diameter grinding drill is smaller, and is generally within the diameter range of an intervertebral foramen mirror grinding drill channel;
2. the intervertebral foramen forming can not grind out bones and remove obstacles under the direct view of an endoscope, but depends on x-ray fluoroscopy, and the positions of grinding, drilling and grinding out the bones and the obstacles are repeatedly confirmed so as to prevent nerves from being injured. Thus, the X-rays are repeatedly seen through, and the X-rays of doctors and patients are exposed too much, so that the operation time is greatly prolonged.
