Description

TECHNICAL FIELD

[0001] The utility model relates to the field of spine endoscope technology. More specifically, the utility model relates to a novel spine endoscope. BACKGROUND

[0002] With the process of global aging accelerating, the patients with spinal degenerative diseases are also increasing, and the patients needing lumbar surgery are also increasing. With the continuous development of surgical instruments and technology, the surgery of the spine gradually changes from traditional open surgery to minimally invasive surgery. Because minimally invasive surgery can not only obtain the same therapeutic effect as open surgery, but also has smaller incision, less intraoperative and postoperative bleeding, and shorter time for patients to recover to normal life and work state after surgery, it not only reduces the social and economic burden, but also enables patients to recover as soon as possible and return to social production.

[0003] Among the diseases of spinal degenerative diseases, the most common are lumbar disc herniation and lumbar spinal stenosis. In the traditional treatment method, besides conservative treatment, it is open surgery. In the 1990s of last century, with the emergence of transforaminal endoscopic minimally invasive surgery, for patients with lumbar disc herniation and lumbar spinal stenosis, surgical treatment gradually changes from traditional open surgery to minimally invasive transforaminal endoscopic surgery. After the development of more than 20 years, transforaminal endoscopic technology has gradually become the "main force" technology for minimally invasive treatment of lumbar disc herniation and lumbar spinal stenosis, and is widely used in the treatment of lumbar disc herniation and lumbar spinal stenosis. However, transforaminal endoscopic minimally invasive surgery has certain limitations. For some patients with severe disc herniation or severe spinal stenosis, transforaminal endoscopic surgery cannot solve the problem. In order to solve the problem of patients with severe disc herniation or severe spinal stenosis, UBE (unilateral double-channel endoscopic spine surgery) technology emerges as the times require. UBE technology uses two channels, one is an endoscope channel, and the other is an instrument operation channel, which is also the biggest difference from the single-channel technology of transforaminal endoscope. UBE technology is suitable for cervical spine, thoracic spine and lumbar spine degenerative diseases. Because its learning curve is relatively flat, the field of view under the mirror is more comprehensive, and the instrument operation is more flexible, it can be called "technology for stenosis". In recent years, UBE technology has been more and more widely used in clinical practice. In recent years, based on the technical concept of UBE technology, new technologies such as OSE (single-hole split endoscopic technology) and AUSS (arthroscopic-assisted single-hole spine technology) have emerged, which are specific manifestations of minimally invasive spine endoscopic technology.

[0004] The UBE technology, the OSE technology and the AUSS technology are all the endoscopic spine surgery technology like the intervertebral foramen mirror technology, but there is no special endoscopic instrument in the market for the UBE technology, the OSE technology and the AUSS technology. In the practical application of the UBE technology, the OSE technology and the AUSS technology, the arthroscope is generally used for the surgery. The arthroscope is composed of an endoscope and a sheath, but in the UBE technology, the OSE technology and the AUSS technology, only the endoscope is used as the observation mirror, and the sheath does not need to be used for the instrument channel, so the sheath does not have substantial effect in the surgery. Moreover, the endoscope and the sheath are not integrally formed, and they are connected through buckles, so that the endoscope and the sheath are loose after the arthroscope is used for a long time, and the buckles are loose, so that the surgeon needs to spend time to solve the problem. At the same time, the loose endoscope and the sheath cause the physiological saline to directly flow out from the sheath, and the water leakage problem occurs. In addition, the endoscope and the sheath need to be assembled with certain experience, so that some surgeons are not familiar with the matching of the endoscope and the sheath, and spend time on the assembly of the endoscope and the sheath, and the surgery time is prolonged.

[0005] In order to solve the above problems, it is necessary to invent a special endoscopic instrument for the UBE technology, the OSE technology and the AUSS technology and other endoscopic spine surgery. Content of the utility model
