Description

technical field

[0001] The invention relates to the technical field of instruments, in particular to an orthopedic minimally invasive surgery regulating expansion device. Background technique

[0002] Neck and shoulder pain, low back and leg pain are common clinical symptoms, most of which are caused by spinal diseases, and some severe cases require surgical treatment. Since the spine is an important physiological structure of the human body, minimally invasive or non-invasive treatment has become an ideal state pursued by spine surgeons. Minimally invasive surgery of the spine has achieved rapid development in the treatment of spinal diseases. However, due to the complex anatomical structure of the spine and the specificity of individuals, it is difficult to accurately reach the lesion area during surgery. Therefore, minimally invasive surgery of the spine has certain risks. and limitations.

[0003] According to the above, in the current clinical operation, it is necessa...
