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 convenient positioning and suturing device for an intervertebral disc herniation fibrous ring, and belongs to the field of medical instruments. The single-needle convenient positioning and suturing device for an intervertebral disc herniation fibrous ring comprises a channel pipe, wherein a pneumatic assembly is arranged in the channel pipe, and suturing assemblies are arranged at the inner end of the pneumatic assembly; and each suturing assembly comprises an arc-shaped cylinder, the diameter of the arc-shaped cylinder is not larger than the inner diameter of the channel pipe, a suturing needle is arranged in the far end of the arc-shaped cylinder, the suturing needle is arc-shaped, the radian of the suturing needle is consistent with that of the arc-shaped cylinder, the suturing needle is arranged in the arc-shaped cylinder in a cooperation manner, a needle head of the suturing needle faces outwards, and an arc-shaped piston is fixed at the tail end of the suturing needle. Multiple needle suturing operations can be realized through one-time operation, suturing is uniform, distances are consistent, it can be guaranteed that fibrous ring cracks are completely closed, besides, the operation difficulty is small, and the cost is low.

Description

technical field [0001] The invention relates to a single-needle convenient positioning and suturing 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 various components of the intervertebral disc (nucleus pulposus, annulus fibrosus, cartilage plate), especially the nucleus pulposus, undergo degeneration of varying degrees. The place protrudes (or protrudes) in the back (side) side or in the spinal canal, which causes adjacent tissues, such as spinal nerve roots and spinal cord, to be stimulated or compressed, 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] Mo...
