Minimally Invasive Surgical Tools for Microdiscectomy Procedures

Stevens Institute of Technology Senior Design project that is focusing on a robotic solution to microdiscectomy procedures of the lumbar spine.

The presented medical device for microdiscectomies deploys two unique robotic arms into the body. Cable-actuated mechanisms controlled by servo motors allow manipulation of the end-effectors to replicate a surgeon’s own hands. The device can move 70 degrees conically and is currently being improved upon to allow for additional axes of movement. There is a quick-assembly system to facilitate preoperative assembly and to serve as a disposable piece to reduce costs and troubles associated with sterilization.
