Knee Arthroscopy Support System

Abstract

The University of Central Florida invention is a semi-robotic arthroscopy support device that surgeons can use while performing knee arthroscopy procedures. Knee arthroscopy is a surgical procedure for treating many knee pathologies, such as meniscus tear, anterior cruciate ligament rupture, and osteochondral lesions. During procedures, surgeons undergo physical and cognitive challenges such as poor visibility of the knee joint and having to switch gazes between the surgical field and the arthroscopic camera feed. They must also handle a tool in each hand and manipulate the patient's leg. Many technologies assist in surgery, such as small continuum robotics for flexible arthroscopes and real-time augmented virtuality using computer navigation. However, surgeons still suffer from poor ergonomics and physical and cognitive strain. As a solution, the UCF device enables a stable arthroscopic camera feed and reduces the physical strain associated with knee arthroscopy. The device can be clamped and suspended without a surgeon holding it.

Technical Details

The UCF knee arthroscopy support system enables surgeons to pause the movement of the working tool with a braking system and re-engage it as needed by releasing the brake. Also, fixed-tool entry positions can create a single coordinated system, providing a stable camera view and tool movement. By preserving the range of motion of conventional arthroscopy and supporting the forces applied during surgery, the device offers a stable intra-articular camera feed, giving the surgeon more control over the procedure. It also enables a workspace for unassisted knee arthroscopy as much as possible due to no longer needing an assistant to hold the arthroscope.

Partnering Opportunity

The research team is looking for partners to develop the technology further for commercialization.
