Description

Technical Field

[0001] The present invention belongs to the technical field of spinal endoscopy, and in particular relates to a spinal UBE and OSE technology endoscope depth limiting device. Background Art

[0002] During spinal endoscopic surgery, the surrounding soft tissue is pushed aside by the working cannula to further expose the surgical field for endoscopic operation. The instrument channel, camera system, light source system and water inlet and outlet channels of the spinal endoscope are long rod-shaped coaxial structures. During operation, the scope tube of the spinal endoscope is extended into the tube opening along the working cannula. During the entire operation, the spinal endoscope needs to use the working cannula as a fulcrum and protective sheath to complete the safe and precise operation of the endoscopic instruments. However, in current operations, the working cannula is hand-held and controlled by the surgeon or assistant, especially the surgeon. An operation often takes 1-2 hours, or even longer. During the entire endoscopic precise operation, the control of the working cannula and avoiding the channel from being too deep to damage the neural structure are extremely challenging to the physical strength and endurance of both the surgeon and the assistant. Excessive fatigue can easily cause the working cannula to lose control and slide to the deep surface, posing a potential huge risk to the spinal cord and nerve roots in front of the tube opening.

[0003] Therefore, there is a need for a spinal endoscope manipulation auxiliary depth limiting device that can overcome the shortcomings of the above-mentioned endoscopic technology operation, such as the application number: 202411048227.3, and the name: A Chinese invention patent for a spinal endoscope OSE technology depth limiting and endoscopic tissue retraction device, which realizes the insertion of the endoscope into the spinal endoscope working cannula and the insertion of surgical instruments into the channel without interfering with subsequent surgical actions, thereby ensuring the smooth completion of the operation.

[0004] However, due to the channel between the working arms, the saline flows out too quickly, making it impossible to stabilize the water pressure and maintain a clear field of view under the microscope. Summary of the invention

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] A spinal UBE and OSE technology endoscope depth limiting device, comprising: a depth limiting base, a clamping mechanism for preventing a spinal endoscope from sliding up and down relative to an endoscope working sleeve, and a clamping mechanism for preventing a spinal endoscope working sleeve from sliding up and down relative to the depth limiting base, wherein the depth limiting base comprises: a support ring, a hollow rod arranged inside the support ring, and a plurality of working arms, wherein the first ends of the plurality of working arms are connected to the support ring, and the second ends are connected to the hollow rod, and a channel for surgical instruments to pass through is formed between two adjacent working arms, and further comprising:

[0012] Furthermore, the water control valve sleeve and the cover plate are integrally formed.

[0013] Furthermore, three working arms are provided, and the three working arms are evenly arranged along the remaining part of the support ring except the notch, and a 120° sector is formed between the notch of the support ring and two adjacent working arms.

[0014] Furthermore, the scope tube of the spinal endoscope and the spinal endoscope working sleeve, the spinal endoscope working sleeve and the hollow rod, and the hollow rod and the water control valve sleeve are all fixed by elastic fixing parts.
