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 a single-needle positioning suture device for an intervertebral disc herniation fibrous ring, which belongs to the field of medical instruments. The single-needle positioning suture device for herniated intervertebral disc annulus fibrosus of the present invention includes a channel tube, a pneumatic component is arranged in the channel tube, and a suture component is arranged at the inner end of the pneumatic component; the suture component includes an arc-shaped cylinder whose diameter is not larger than The inner diameter of the channel tube, the suture needle is arranged inside the far end of the arc-shaped cylinder, the suture needle is in the shape of an arc, and its radian is consistent with the arc of the arc-shaped cylinder, the suture needle fits in the arc-shaped cylinder, the needle head of the suture needle is set outward, and the suture needle The tail end is fixed with an arc-shaped piston. 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 a single-needle positioning suture device for an intervertebral disc herniation fibrous ring, which belongs to the field of medical instruments. 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 metho...
