AI Technical Summary
In current spinal surgery, displacement caused by respiratory movements severely interferes with the positioning accuracy of surgical instruments. Existing technical solutions are either too costly or lack sufficient compensation accuracy, making them difficult to popularize in small and medium-sized hospitals.
A passive respiratory compensation system is adopted, including a respiratory signal monitoring module, a spinous process follow-up locking module, and a surgical arm follow-up locking module. Through the synchronous movement of the spinous process clamp and multi-degree-of-freedom follow-up mechanism with the main body of the surgical arm, combined with the electromagnetic mechanical locking mechanism, rigid locking is achieved at the moment of end of expiration, eliminating dynamic errors caused by respiratory motion.
It achieves high-precision static surgical results, reduces hardware costs and algorithm dependence, simplifies operation, and improves surgical efficiency and smoothness.
