Problems solved by technology

[0004] At present, most of the surgical instruments for facet joint repair surgery in the domestic market are sorted out from commonly used instruments, which not only wastes time, but also affects surgical efficiency and delays surgical treatment; in addition, there are many facet joint surgical instruments in the domestic market. Imported from abroad, and the physiological characteristics of people in different regions are different, so that the specifications, sizes, angles, and configurations cannot fully meet the needs of Asians. Therefore, it is very important to design a small joint repair surgical instrument kit suitable for Asians.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a facet joint repair operation instrument kit. Background technique [0002] The facet joints are synovial joints, located in the posterior column of the spine, they bear 20% of the stress of the spine, and their surfaces are covered with hyaline cartilage. This joint has a strong connective tissue capsule that contains synovial fluid, and synovitis in these joints can cause low back pain. The facet joints play an important role in the stability of the spine, and their anatomical position and orientation affect the range of motion in different regions of the spine. Degeneration or damage to the facet joints can lead to dysfunction during the motor phase. The direction of the facet joints of the cervical spine is in the coronal plane. It has no restrictions on flexion, lateral bending and rotation, but has a slight limit on extension, so the range of motion of the ce...
