Fibrous ring stitching instrument under spine endoscope

Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to a fibrous ring stitching instrument under a spine endoscope. The fibrous ring stitching instrument under the spine endoscope comprises a main body, a curved needle used for stitching operation is arranged at the front end of the main body, a straight needle is further arranged at the front end of the main body, and a tray used for supporting the main body is arranged at the position, close to the front end, of the main body. A storage box used for preventing cross infection is arranged at the front end of the curved needle, and a clamping plate used for preventing the main body from shaking is arranged at the upper end of the tray. The tray is placed on a patient, so that the main body can be placed in the tray, a spring telescopic rod drives the clamping plate to clamp and fix the main body to prevent shaking, the stability of the main body is improved, and smooth operation is guaranteed; a puncture needle is guided through a first guide plate and a second guide plate to be contained in the straight needle, the puncture needle is further bent and hung at the upper end of a hanging plate through an arc-shaped plate, loosening can be effectively prevented, secondary contact between the puncture needle and the patient is avoided, and the comfort of the patient is improved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an annulus fibrosus stapler under spinal endoscope. Background technique [0002] Intervertebral disc nucleus pulposus extraction is a common surgical method for the treatment of intervertebral disc herniation. It can achieve good clinical curative effect, but it needs to damage or cut the fibrous annulus, which will lead to the destruction of the integrity of the fibrous annulus, accelerate the degeneration of the intervertebral disc, and decrease the biomechanical function. Annulus fibrosus suture repair can significantly improve the clinical symptoms of low back and leg pain, reduce postoperative recurrence rate and reoperation rate, and reduce the medical expenses of reoperation patients. In order to improve the operation efficiency, a spinal endoscopic annulus stapler is usually used. [0003] The original annulus fibrosus stapler requires high stabilit...

AI Technical Summary

Problems solved by technology

[0003] The original annulus fibrosus stapler requires high stability to ensure the smooth progress of the operation. There is no device to assist the doctor to fix the stapler, resulting in low work efficiency and prolonged operation time. The rod is exposed on the outside, and the puncture needle has a large contact area with the patient during recovery, which will cause discomfort to the patient and reduce the surgical effect. Due to the single-thread suture used in the suture operation, the accuracy of the position is high, and an auxiliary device is required for positioning suture , and if the stapler is not protected after use, it will increase the chance of cross-infection
