Problems solved by technology

However, if more complicated spinal surgery such as endoscopic spinal internal fixation is carried out, since spinal internal fixators such as fusion cages, steel plates, and pedicles usually have a large volume or extend out of the working channel for a long time, the existing The endoscopic working channel will appear powerless
[0004] In actual use, because fusion cages, steel plates, pedicles, etc. will block the observation of the endoscope, there will be obvious blind spots in the field of vision, and the operator feels a lot of pressure. Squeeze important tissues such as nerves, which not only increases the difficulty of operation but also brings great risks to endoscopic spinal internal fixation surgery

Embodiment 1

[0041] Embodiment 1, taking cooperation with cervical posterior laminoplasty as an example.

[0042] A small incision was taken in the middle of the back of the cervical spine, and the skin, subcutaneous tissue, and nuchal ligament were incised in sequence. First place the working channel on the surface of the lamina next to the spinous process on one side. Install the endoscope through the left endoscope fixing hole 7 or the right endoscope fixing hole 8, and then adjust the focal length and the direction of view. After the soft tissue is cleaned up, use a burr or lamina rongeur to open a bone groove for decompression along the long axis of the human body.

[0043] Then, select a suitable length of micro-titanium plate and bend it, and place it in the steel plate groove 5 of the expansion cylinder 1 . Then, punch a hole in the side block, and fix one end of the steel plate 14. The endoscope 3 is installed in the rear endoscope fixing hole 9 again to adjust the focal length...

Embodiment 2

[0045] Embodiment 2, taking the unilateral intervertebral approach for lumbar instability as an example.

[0046] Take the corresponding part of the body surface of the intervertebral space of the unstable segment and make a small posterior midline incision, and unilaterally incise the lumbar dorsal fascia along the side of the spinous process to insert the present invention. Afterwards, the endoscope 3 is installed in the left endoscope fixing hole 7, and the focal length and the direction of view are adjusted simultaneously. After a small bone window was opened in the lamina, the ligamentum flavum was separated and excised to expose the dural sac and nerve roots.

[0047]According to the actual situation, the nerve root is retracted with the multifunctional sheet 10 to expose the intervertebral disc, the nucleus pulposus tissue is resected, and the upper and lower end plates are scraped off. Moreover, when the first fusion device is inserted, the endoscope 3 is installed in...

Abstract

The invention relates to a panoramic spinal endoscope device, which includes an expansion tube on which an endoscope support column is installed. Assemblies, a soft tissue retractor is arranged above the expansion cylinder. Simultaneously, the tail of the endoscope support column is provided with a number of fixing holes, the endoscope support column is connected with a multifunctional sheet assembly, and the endoscope support column is provided with an auxiliary fixing assembly. Thus, the switch between the single endoscope structure and the double endoscope structure can be used, that is, the left and right sides of the internal fixator and even the part outside the expansion cylinder can be seen in time-sharing, and panoramic observation without dead angle can be realized. It can also eliminate the dead angle of observation and realize the effect of 3D stereoscopic observation.

Description

technical field [0001] The invention relates to an auxiliary instrument for spinal minimally invasive surgery, in particular to a panoramic spinal endoscope device. Background technique [0002] There are many types of endoscopes currently used for minimally invasive spinal surgery, including discoscopy, foraminal microscopy, laparoscopy, and thoracoscopy. In actual operation, they must first establish a working channel when they work. Specifically, it includes a single cylindrical shape (endoscope, suction device, forceps and other instruments pass through a channel), or a multi-hole conical shape (endoscope, suction device, forceps and other instruments pass through the corresponding channel), and the skin, muscle, etc. Wait for the soft tissue to get out of the way. Then, insert the endoscope and use various instruments to complete different technical operations through the lumen of the working channel, such as nucleus pulposus removal and simple decompression. [0003...
