Unilateral dual-channel spinal endoscope

Abstract

The invention discloses an unilateral dual-channel spinal endoscope. The unilateral dual-channel spinal endoscope comprises an endoscope, an endoscope sheath and a hole closing device, the endoscope sheath comprises an endoscope sheath main body and a sheath tube, an endoscope sheath head is fixedly welded to the head of the sheath tube, an endoscope assembling hole is arranged in the endoscope sheath main body, a buckle is arranged at the top of the endoscope sheath main body, and clamping grooves are provided in the hole closing device and the endoscope main body. Protruding parts and limiting parts are symmetrically arranged on the buckle in the radial direction, the buckle is fixed between the top cover and the endoscope sheath main body, the protruding parts of the buckle protrude outof the outer side of the top cover from a notch in the side edge of the top cover, limiting grooves corresponding to the limiting parts in position are arranged in the top cover, springs are fixed inthe limiting grooves, and the other end of the spring are sleeved on the limiting part. A water receiving pipe is further arranged on the endoscope sheath main body, a multifunctional connector is arranged at the end of the water receiving pipe, and the multifunctional connector and the water receiving pipe are of an integrated structure. The endoscope of the invention is simple in structure andreasonable in design, and preoperative preparation work can be reduced, the operation time is shortened, the operation risk is reduced, and the operation success rate is increased.

Description

technical field [0001] The invention relates to a spinal surgery appliance, in particular to a unilateral dual-channel spinal endoscope. Background technique [0002] There are two commonly used techniques for the treatment of spinal diseases such as intervertebral disc herniation, intervertebral stenosis, and intervertebral fusion, one is the minimally invasive transforaminal technique, and the other is traditional open surgery. The development of spinal minimally invasive endoscopic technology is becoming more and more mature, especially the rapid popularization of foraminal endoscopic technology nationwide. Foramoscopy is a single channel, the scope of operation is affected, and the use of surgical instruments is limited. It has advantages in the treatment of intervertebral disc herniation, but it is more difficult to treat other spinal diseases such as intervertebral stenosis. A new minimally invasive surgery is currently popular, unilateral dual-channel endoscopic tech...

AI Technical Summary

Problems solved by technology

[0003] 1. Existing borrowed endoscopes and accessories are complicated to assemble during actual use, and the links of endoscopes and accessories are easy to fall off during use

[0004] 2. Existing endoscope accessories have complex structures

Inconvenient to use

[0005] 3. In the single-sided dual-channel technology, there is a high requirement for saline control. When using traditional endoscope accessories, the operator will misuse it to turn it off or reduce the water intake, which will affect the surgical effect.

[0006] The existence of the above problems restricts the use of endoscopes and accessories in unilateral dual-channel endoscopic technology, which increases the operation time and difficulty.
