Benefits of technology

Introduced into this new technology described in this patents allows surgeons to work within minimal physical constraints while still being able to see what they have done during procedures without causing any harm or injury themselves. It uses specialized structures called robots (a type of machine) attached to the arms of the microsurgery robot. These robots move around inside the operating room under guidance provided by computer programs running them. They use wireless signals sent between their actuators and sensory devices like cameras to provide visual confirmations about how far away objects were seen beforehand. By doing these operations autonomously, the microscopic medical team does less effort than traditional methods. Overall, this innovative technical means improve the functionality and usability of the robot systems used in neurosurgeries.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance of minimal invasively surgery robots without compromising their safety or comfort level during movement. Current methods involve either reducing body weight or increasing muscle strength, making them heavier than usual. Additionally, existing techniques require multiple motors to generate six degrees of rotation per second, leading to longer operating times.
