Description

Technical Field

[0001] The utility model relates to the technical field of medical tools and equipment, in particular to a UBE endoscopic soft tissue spreader. Background Art

[0002] UBE (Unilateral Double-Channel Endoscopic Discectomy) is performed under water. During the procedure, a cavity is artificially created on the surface of the vertebral lamina and adjacent muscles. After the cavity is created, a fenestration is performed to allow for intraspinal decompression. Water pressure is typically used to maintain the cavity, which can cause muscle bundles to float in the water, obscuring the surgical field of view.

[0003] Therefore, there is an urgent need for a UBE endoscopic soft tissue expander to solve the problem that muscle bundles float with the water in the artificially created cavity under water medium, thereby affecting the surgical field of view. Utility Model Content

[0004] The utility model provides a UBE endoscopic soft tissue spreader to solve the problem that muscle bundles float with water in an artificially created cavity under water medium, thereby affecting the surgical field of view.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A UBE endoscopic soft tissue expander, comprising:

[0007] The bracket is a plastic structural member and has a hollow cylindrical structure, and the side surface of the bracket is in a grid shape;

[0008] The balloon is arranged in the bracket, and the balloon is in the shape of a truncated cone when expanded. The balloon is provided with an air inlet pipe, and the air inlet pipe is provided with a switch valve. The end of the air inlet pipe is detachably connected to the air inlet pump.

[0009] Furthermore, the balloon is wrapped around the air intake pipe, one end of the air intake pipe away from the air intake pump is closed and provided with an arc-shaped surface end, and a plurality of air holes are distributed on the air intake pipe, and the air holes connect the balloon and the air intake pipe.

[0010] Furthermore, the air inlet pipe is provided with two annular grooves, and both ends of the bracket are provided with annular protrusions that match the annular grooves.

[0011] Furthermore, a pressure gauge is provided on the air intake pipe.

[0012] Furthermore, the output end of the air intake pump is provided with an external thread, and one end of the air intake pipe is provided with an internal thread matching the output end of the air intake pump.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] In actual use, the balloon is placed in the soft tissue at the surgical site and then inflated. The balloon expands, expanding the stent, which assumes a truncated cone shape and forms an operating cavity within the soft tissue. Finally, the balloon is deflated to reduce its volume, and then removed from the soft tissue. The stent blocks the muscle bundles outside the operating cavity, thus preventing interference with the surgical field of view. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be described in detail below with reference to the accompanying drawings.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] This embodiment provides a UBE endoscopic soft tissue expander, such as Figure 1-Figure 2 Shown, including:

[0022] The bracket 1 is a plastic structural member and has a hollow cylindrical structure, and the side surface of the bracket 1 is in a grid shape;

[0023] The balloon 2 is arranged in the bracket 1. When the balloon 2 is expanded, it is in the shape of a truncated cone. An air inlet pipe 3 is arranged on the balloon 2. A switch valve 4 is arranged on the air inlet pipe 3. The end of the air inlet pipe 3 is detachably connected to the air inlet pump 5.

[0024] In actual use, balloon 2 is placed into the soft tissue at the surgical site and then inflated. The balloon expands, expanding stent 1, which assumes a truncated cone shape and forms an operating cavity within the soft tissue. Finally, balloon 2 is deflated to reduce its volume, and then removed from the soft tissue. Stent 1 blocks the muscle bundles outside the operating cavity, preventing interference with the surgical field of view.

[0025] The above embodiment is further optimized in that the balloon 2 is wrapped around the air inlet tube 3. The end of the air inlet tube 3 away from the air inlet pump 5 is closed and provided with a curved surface end 7. The air inlet tube 3 is provided with a plurality of air holes distributed thereon, which connect the balloon 2 with the air inlet tube 3. The curved surface end 7 can be inserted into soft tissue, and this structure facilitates better placement of the balloon 2 into the soft tissue.

[0026] In a further optimization of the above embodiment, two annular grooves are provided on the air inlet pipe 3, and annular protrusions are provided at both ends of the stent 1 to match the annular grooves. This structural arrangement ensures that the stent 1 will not detach from the balloon 2 during the process of entering the patient's soft tissue.

[0027] To further optimize the above embodiment, a barometer 6 is provided on the air inlet pipe 3. The barometer 6 can display the air pressure, so as to better control the expansion degree of the balloon 2 to avoid damage to the internal muscles caused by excessive expansion.

[0028] In a further optimization of the above embodiment, the output end of the air pump 5 is provided with an external thread, and one end of the air intake tube 3 is provided with an internal thread that matches the output end of the air pump 5. This structural arrangement facilitates separation of the air intake pump 5 from the air intake tube 3, thereby facilitating the later deflation and removal of the balloon 2 from the patient's soft tissue.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
