Technical Field

The invention relates to the technical field of medical instruments, in particular to a novel large-channel endoscope device system for lumbar decompression and intervertebral fusion.

Background

With the development of precise medicine, the precision and the minimally invasive of the spine surgery are more and more favored. At present, the spine minimally invasive system which is widely applied clinically and mature is mainly used for the intervertebral foramen mirror of the lumbar vertebra and various expandable channel technologies. The foramen mirror system has the main advantages that the endoscope and the high-definition camera system are provided, the principle similar to a laparoscope principle is adopted, the operating sleeve is placed step by step through percutaneous puncture to the focus, the herniation of the nucleus pulposus of the intervertebral disc can be rapidly and effectively completed, the percutaneous incision is about 7mm, the muscle tissue is not damaged, the wound is small, the bleeding is less, and the patient can be discharged from the hospital within 24 hours after the operation. The foramen mirror operation belongs to a part of ladder treatment, and most of the foramen mirror operations can not be solved by a simple foramen mirror technology, and patients such as lumbar spondylolisthesis and spinal stenosis need to adopt decompression fusion internal fixation.

To further achieve the minimally invasive procedure of the conventional lumbar decompression fusion, Schwender et al reported that the basic procedure of the conventional decompression fusion procedure was performed by using a minimally invasive technique of an expandable channel that was accessed through the muscular space at the posterior and lateral sides, placing a channel through the muscular space at the lumbar and back through an incision of 30-40mm in the skin, and displaying the structures around the spine by expansion of the channel, without requiring any camera and image display system, and expanding the space inside the incision by means of a dilator inside the incision. However, this technique is more traumatic than the borescope technique and is considered to be an open surgery after reduction because there is a certain degree of traction that causes nerve damage and bleeding complications.

However, the existing borescope working cannula system is designed for pure nuclectomy, the decompression range of the vertebral canal is very limited, and most importantly, the existing borescope working cannula system cannot complete the intervertebral fusion. And the wound of the expansion traction tissue in the channel body of the channel technology is increased compared with the foramen lens, the injury risk is increased, the camera shooting function of a foramen lens system is not provided, and most importantly, the lateral channel can well complete the intervertebral fusion, but the effective spinal decompression can not be realized.

Therefore, in view of the defect that the existing lumbar minimally invasive system cannot take both decompression and intervertebral fusion into consideration, how to provide a high-definition camera system with a borescope system to enlarge the operation field of vision so as to reduce the expansion range and damage of the channel, and how to place the high-definition camera system into the intervertebral fusion device so as to achieve a novel lumbar decompression and intervertebral fusion large-channel endoscopic device system which can realize the lumbar fusion while realizing the lumbar canal decompression operation by placing the focus through the minimum working sleeve through percutaneous puncture, is an urgent problem to be solved by technical personnel in the field.
