Embodiment Construction

[0017] This manual has taken the annulus fibrosus suturing device for minimally invasive percutaneous intervertebral disc surgery under an endoscope as an example to describe the structure and specific usage of the present invention in detail:

[0018] like figure 1 As shown, the stapler a is made of stainless steel, in which 1 is the needle shaft, 2 is the needle point, and 3 is the hole on the needle point. The shape of the hole is round or oval. The lateral width of the shape is designed to be 1.5mm. like figure 2 As shown, in the process of minimally invasive surgery, the working channel 6 is established first, and after the treatment of the nucleus pulposus is completed, the absorbable thread is passed through the hole 3 at the front of the needle tip, and then the stapler is brought into the working channel 6 together with the two threads , through the endoscope to confirm that it reaches the damaged part of the annulus fibrosus 5, the advantage of using absorbable su...

Abstract

The invention belongs to an improvement in a surgical instrument, and discloses a fibrous ring stapler for percutaneous full-endoscopic minimally-invasive discectomy. The stapler comprises a needle bar (1) and a needle point (2), and is characterized in that the needle point (2) is bent into a hook shape, wherein a threading hole (3) is formed in the front end of the needle point (2). When the stapler with a suture is used, the stapler enters a working passage (6), and is determined by an endoscope to reach a damage of a fibrous ring (5), the needle point with the suture penetrates through one side of the damaged fibrous ring from inside to outside, the threading hole (3) and the two sutures behind are exposed from the fibrous ring, and one suture behind the threading hole is clamped by a clamping device (7), is led out of the threading hole along the working passage, is brought to an area which is convenient to operate outside the working passage at the same time, and penetrates through the other side of the fibrous ring; at the moment, the two free ends of the absorbing suture penetrate through the two opposite sidewalls of the fibrous ring respectively, and are knotted, and knots are fixed by a knotting propeller.

Description

technical field [0001] The invention belongs to the improvement of surgical instruments, in particular to the annulus fibrosus suturing for percutaneous intervertebral disc surgery under full endoscope in the field of minimally invasive spinal surgery. Background technique [0002] According to the statistics of the national health department, the number of patients with intervertebral disc herniation in my country has been on the rise for many years, and has expanded from middle-aged to young adults at an alarming rate year by year. The most common cause of the disease is that various parts of the intervertebral disc, such as the nucleus pulposus, annulus fibrosus, and cartilage plate, especially the nucleus pulposus, undergo degenerative changes to varying degrees. The rupture protrudes from the back or into the spinal canal, causing the adjacent nerve roots to be stimulated or compressed, resulting in a series of clinical symptoms such as pain, numbness, and pain. After ...
