Embodiment 1

[0029] Example 1: Such as Figure 1 to Figure 9 The operating device for suturing the annulus fibrosus after nucleus pulposus removal includes suture hooks, thread catchers, thread pushers, and thread scissors. Such as Figure 1 to Figure 3 The suture hook with thread shown is made up of a first handle 11 and a suture hook body, the bottom of the suture hook body is bent upward from one side to form a crotch 15, and the crotch head is in the shape of a needle point, and the crotch head is provided with a thread for the suture to pass through. The top of the first handle 11 is provided with an indicator arrow 14 corresponding to the crotch, and the indicator arrow 14 points to the crotch side of the corresponding seam hook body. The indicator arrow 14 is symmetrically divided into a dark zone and a light zone. Used to indicate both sides of the hook 15. The first handle 11 is a bottom-shrinking cylinder with a length of 100 mm and a top diameter of 15 mm; the seam hook body...

Abstract

The invention discloses an operation device for suturing the annulus fibrosus after discectomy. The operation device comprises a suturing hook with a line and a line hooking device matched with the suturing hook with the line, wherein the suturing hook with the line is composed of a first handle and a suturing hook body; the bottom of the suturing hook body is upwards bent from one side to form a bent hook; the head of the bent hook is in a needle point shape and provided with a line seam allowing a suture line to penetrate through; the first handle is provided with an indicating mark corresponding to the bent hook and distinguishing the two sides of the bent hook; the line hooking device is composed of a second handle and a line hooking body; the bottom of the line hooking body is upwards bent from one side to be arc. Suturing of the annulus fibrosus is achieved in a limited space, the success rate of operation is high, the cost is low, the edge distance of the sutured soft tissue and the suturing depth can be controlled in the operation process, and the process is safe and controllable.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an operating device for suturing annulus fibrosus after nucleus pulposus removal. Background technique [0002] Since the simple laminectomy fenestrated nucleus pulposus was carried out clinically, it has relieved the pain of countless patients, but the high secondary recurrence rate after the operation still brings great pain to the patients. At the same time, the annulus fibrosus Scar healing also brings great challenges to the second treatment. At present, it is believed that suture fixation after annulus incision has a clear effect on the biomechanical stability of the vertebral body and the prevention of secondary recurrence after surgery. However, intervertebral disc suturing is quite difficult. The main reason is that the fibrous annulus is located in a relatively deep position after simple fenestration and decompression. There is no way to complete the suture operation wit...
