Description

Technical Field

[0001] The utility model relates to the technical field of endoscopes, in particular to a spinal endoscopic surgery positioning device. Background Art

[0002] Bending over for long periods of time can cause lumbar disc herniation. Spinal endoscopic treatment of lumbar disc herniation is a minimally invasive surgical method. The incision of this surgery is only about seven millimeters. Spinal endoscopic surgery can effectively improve the pain caused by lumbar disc symptoms, and most patients can be discharged from the hospital after one day of hospitalization.

[0003] Existing spinal endoscopic surgeries require the use of a working cannula, in which the spinal endoscope and specific tools work. However, the prior art often uses a multi-stage cannula positioning method. During the operation, there is a problem of the working cannula slipping due to inaccurate positioning. The working cannula will shift in the opposite direction of the resected tissue or to the side, making it easy for the working cannula to move, thereby affecting the surgical effect. How to invent a method to improve these problems has become an urgent problem to be solved by technical personnel in this field. Utility Model Content

[0013] By adopting the above technical solution, when inserting the insert strip into the slot, the inner wall of the positioning sleeve will squeeze the rubber strip, thereby increasing the friction between the positioning plug and the positioning sleeve, ensuring a firm connection between the two while avoiding the appearance of gaps.

[0014] Preferably, a groove is provided on the side wall of the positioning plug away from the card block, the inner wall of the groove is fixedly connected to the magnetic block, the size of the groove is larger than the size of the magnetic attractor, and the magnetic attractor is magnetically connected to the magnetic attractor.

[0015] By adopting the above technical solution, after the positioning plug is inserted into the positioning sleeve, the magnetic attraction iron and the magnetic attraction block can be connected, further increasing the firmness of the connection between the two.

[0016] The beneficial effects of the utility model are:

[0017] The insert strip is inserted into the slot and the rubber strip is squeezed to increase the friction between the positioning plug and the positioning sleeve, ensuring a firm connection between the two while avoiding gaps; then the magnetic iron is connected to the magnetic block to further increase the firmness of the connection between the two, thereby avoiding displacement and ensuring the surgical effect; and external force can be applied to the block to facilitate the subsequent separation of the positioning plug and the positioning sleeve; in addition, scale lines are provided on the outer wall of the sleeve to prevent the sleeve from being inserted too deeply, thereby ensuring the safety of the operation as a whole; at the same time, the sleeve and the shaft sleeve are fixedly connected to the positioning plug respectively, and the sleeve can be knocked during use to ensure the accuracy of the subsequent use of the inner core.
