Neck and shoulder ache, pain in waist and lower extremities are symptoms common in clinic, and most of is caused by spinal disease, and part severe patient needs to perform the operation
Treatment.Since backbone is the important physiological structure of human body, minimally invasive or non-invasive therapy has become spinal surgery doctor pursuit
Ideal state.Minimally invasive spine surgical achieves fast development in terms for the treatment of spinal disease, but since spinal anatomy is multiple
Miscellaneous and individual there are certain specificity, surgical procedure, which will accurately reach lesion region, has larger difficulty, therefore vertebral column minimally invasive
Operation has certain risk and limitation.
According to above-mentioned, in Present clinical operation, need effectively to expand operative site visual area, that is, reach raising hand
Art operates purpose, but traditional expander at present, and common configuration is simple, has a single function, and has the following disadvantages, and 1, because of existing expansion
Device is mostly hard drawing expansion structure, is easy to generate damage to patient's wound tissue in process of expansion, improves patient's hand
The risk of art, 2, can not by simple rotation process to operative site carry out well expansion support, reduce visual area space,
Strong influence finally is brought to subsequent surgical procedure, is unfavorable for clinical popularization and application, in view of disadvantages described above, it is really necessary to
Design a kind of orthopaedics Minimally Invasive Surgery adjusting extension fixture.
