Problems solved by technology

Due to the difference in the manual suturing action during each suture, the suture is not neat and the spacing is not uniform. If the spacing is too large, the suturing effect will not be achieved, causing the nucleus pulposus to protrude again

Abstract

The invention relates to an annulus fibrosus suture device and a suture method after intervertebral disc herniation, belonging to the field of medical devices. It includes a sleeve, a pneumatic component is set inside the sleeve, and a suture component is set at the inner end of the pneumatic component; the suture component includes an arc-shaped guide cylinder, the diameter of which is not greater than the inner diameter of the sleeve, and arc-shaped left needles are respectively set at both ends of the guide cylinder And the right needle, the left needle and the right needle are all arc-shaped, and its radian is consistent with the radian of the guide cylinder. The left needle and the right needle are matched in the guide cylinder, and the left needle and the right needle are set outward. Multiple needles can be sutured in one operation, and the sutures are even and the spacing is consistent, which can ensure the complete closure of the fibrous annulus fissure, and at the same time, the operation is less difficult and the cost is low.

Description

technical field [0001] The invention relates to an annulus fibrosus suture device and a suture method after intervertebral disc herniation, belonging to the field of medical devices. Background technique [0002] Intervertebral disc herniation is one of the more common spinal diseases in clinical practice. The main reason is that the components of the intervertebral disc (nucleus pulposus, annulus fibrosus, and cartilage plate), especially the nucleus pulposus, undergo degeneration of varying degrees. Protrusion (or prolapse) in the back (side) side or in the spinal canal, resulting in stimulation or compression of adjacent tissues, such as spinal nerve roots and spinal cord, resulting in a series of clinical symptoms such as neck, shoulder, low back pain, numbness, etc. symptom. According to the location of the disease, it is divided into cervical disc herniation, thoracic disc herniation, and lumbar disc herniation. [0003] Most of the current treatment methods use ope...
