Fibrous ring suturing operation device after discectomy for lumbar disc herniation

Abstract

The invention discloses a fibrous ring suturing operation device after discectomy for lumbar disc herniation. The fibrous ring suturing operation device after discectomy for lumbar disc herniation comprises a suture needle and a suture line, wherein the suture needle comprises an operation handle and a suture hook; the suture hook is fixedly arranged on the operation handle; the operation handle and the suture hook are in a split structure; the suture hook is provided with a suture line connection part; the suture like is connected with the suture hook into a whole through the suture line connection part; a hook tip breaking structure is arranged at one side, far away from the hook tip, of the suture line connection part. When the device is adopted for fibrous ring suturing, only the hook tip of the suture hook needs to be broken off and extracted by a needle holder after threading is ended, so that the fussy and difficult process of looking for the line head is avoided; the suturing time is greatly shortened. Only the hook tip with relatively low price in the device is disposable consumable, so that the treatment cost of a patient is effectively reduced; the edge distances of sutured soft tissues and the suturing depth can be controlled by the fibrous ring suturing operation device; the gap between soft tissues is overcome. The fibrous ring suturing operation device is reasonable in structure, small in operation error and high in surgical successful rate.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an annulus fibrosus suture operation device after excision of the nucleus pulposus of lumbar intervertebral disc herniation. 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 decompress...
