Annulus fibrosus suture device for lumbar disc herniation after minimally invasive excision of nucleus pulposus

Abstract

The invention discloses a fibrous ring suturing device used after lumbar disc herniation nucleus pulposus minimally invasive enucleation. The fibrous ring suturing device comprises a suture needle body and a suture thread, wherein the suture needle body comprises a guide needle thread and a guide needle sleeve; the guide needle sleeve is arranged on the guide needle thread in a sleeving manner and is limited by a limiting device on the guide needle thread; the suture thread is integrally connected with the guide needle thread through a suture thread connecting device. The fibrous ring suturing device is simple and reasonable in structure and easy to operate, can be used in the wound suturing process of a minimally invasive surgery, and can suture rupture surfaces with different shapes. Under the synergy of an aperture mirror, the entire operation is within a visible range, the process is safe and controllable, and the problems that after a nucleus pulposus enucleation under the conventional aperture mirror, the fibrous ring suturing process is complicated, low in efficiency and high in cost, consumes long time and is likely to cause secondary harm are solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a tool for treating lumbar intervertebral disc herniation, in particular to an annulus fibrosus suture device for minimally invasive excision of the 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 relativel...
