Description

Technical Field

[0001] The utility model relates to the technical field of surgical equipment, in particular to an observation device used in posterior lumbar surgery. Background Art

[0002] Posterior lumbar surgery means opening the vertebral lamina in the patient's back, removing the intervertebral disc, and opening the spinal canal to relieve the pressure on the nerve roots. Some patients may also need posterior pedicle screw fixation. After pedicle screw fixation, the stability of the lumbar spine is restored, and intervertebral bone grafting and fusion are required. An intervertebral fusion device may be placed, as well as fusion fixation between the articular processes. During the posterior lumbar surgery, observation equipment is required to observe the joint position to ensure the normal operation of the entire operation.

[0003] Generally, during posterior lumbar surgery, the outside of the patient's lumbar spine needs to be exposed, which not only requires depth, but also requires the skin to reach the bone level. When you need to reach the bone level, you need to expose it outward, all the way to the articular process. In this case, during the operation, it is necessary to pull outward. During the pulling process, the difficulty will increase. The second is when it is necessary to look at a joint deep in the same side, the surgeon needs to bend over and lean his head over to observe the position of the joint. During the long surgical operation, the surgeon will suffer from back pain. Therefore, an observation device for use in posterior lumbar surgery is proposed to solve the above problems. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides an observation device for use in posterior lumbar surgery, which has the advantages of being able to facilitate the operator to observe the position of the ipsilateral joint, facilitating the operation, and reducing the operator's fatigue. It solves the problem that in general posterior lumbar surgery, the patient's lateral lumbar spine needs to be exposed, which not only requires depth, but also requires the skin to reach the bone level. When you need to reach the bone level, you need to expose it outward until the articular process is exposed. In this case, during the operation, it is necessary to pull it outward. During the pulling process, the difficulty will increase. Secondly, when it is necessary to see a joint deep in the ipsilateral layer, the operator needs to bend over and lean his head over to observe the joint position during the observation of the articular process. During the long surgical operation, the operator will suffer from back pain.
