Description

Single door surgical instrument bag

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a single door surgical instrument package.

Background

Posterior single-door spinal canal expansion and shaping of cervical vertebrae is a major method for treating multi-segment spinal cord diseases, cervical canal stenosis, and multi-segment posterior longitudinal ligament ossification, which is to cut one side of a lamina through a surgical operation and implant a mini-door titanium plate to displace the lamina to the posterior and lateral sides to expand the spinal canal. The miniature door-opening titanium plate forms a stable bridging structure between the lifted vertebral plate and the ipsilateral side block, can form a real rigid support at the door-opening side, maintains the post-operation spine structure to be fixed at the position during operation, and realizes immediate stability. The miniature door-opening titanium plate not only can effectively prevent the door from being closed again after operation or the door opening angle from being reduced, but also can improve the stability of the door shaft side, is favorable to the bone healing of the door shaft side, and prevents the physiological curvature of the cervical vertebra from being further lost.

Besides, the miniature door-opening titanium plate technology can also effectively reduce the incidence rate of axiality symptoms, and the reasons are as follows: 1. the technique avoids the interference and damage to the posterior branch of the cervical nerve and the aseptic inflammation caused by the relative traction to the joint capsule when the suture is used for suturing and fixing the small joint capsule, and reduces the interference to the small joint capsule to a lower limit; 2. the titanium plate with the miniature door is low in notch, so that the surrounding tissues can be prevented from being stimulated to generate inflammatory symptoms; 3. the technology is firm in fixation, and the patient can perform functional exercise at an early stage, prevent neck muscle atrophy and tissue adhesion, effectively maintain normal physiological forward protruding of the cervical vertebra, improve the mobility of the cervical vertebra and reduce uncomfortable feeling caused by wearing the cervical brace for a long time.

At present, in the process of performing a cervical vertebra posterior single-door operation, various instruments are required to be adopted to complete the operation, and a doctor selects corresponding tools to perform the operation according to different operation stages during the operation, however, as all tools of the operation are put together, the traditional Chinese medicine needs to be continuously identified in the operation process, and the operation is inconvenient to perform; in addition, the practice shows that the conventional instrument has larger limitation in the cervical vertebra posterior single-door opening operation process, has complex operation and poor suitability, and is difficult to accurately and effectively realize the implantation of the single-door opening plate.
