Meril's new Misso robot

Meril last week unveiled its Misso surgical robot for simplifying orthopedic procedures.

""Meril claims that the robot has a success rate of 98 per cent and  is ideal for small hospitals as it leaves the smallest footprint in the OR among the existing robotic system. Additionally it will reduce the investment in such systems by  66 per cent, making these surgeries more accessible and affordable. So far the technology has received approval from CDSCO and is queued up for CE and USFDA approvals.'"

"The robotic solution offered by Meril consists of a ‘Vision’ cart, a robotic arm, and a Misso planner. The cart acts as a potent computing core, with a 27-inch medical-grade touch monitor and the NDI Polaris Optical Tracking System (OTS).

The next-generation robotic arm integrates intelligent sensors for adaptive performance. This sleek, six-axis collaborative arm operates smoothly and silently, offering advanced maneuverability in multiple directions.

According to Meril, its adaptive bone tracking ensures precise and efficient movement, making it suitable for a wide range of tasks requiring delicate handling and precision.

The Misso planner provides flawless surgical planning, utilizing AI-based segmentation for enhanced accuracy. It features automatic implant size detection and can identify implant overhang and notching, ensuring optimal outcomes for surgical procedures."

The India-based company announced on LinkedIn that it is developing a total knee surgical robot. It designed Misso to help surgeons with personalized pre-planning and precise cutting for joint replacement surgery.

According to Meril, Misso has an optical tracking sensor, a six-axis articulated robotic arm and “superior” safety systems. The surgical robotic system helps physicians perform real-time gap checks and modify a surgical plan intraoperatively.

Various cutting options are available on the Misso, including full and partial cutting based on surgeon preference. Cutting guides are not required and the system can perform a tibial cut and a fully finished femur with all the cuts, including peg holes.

Meril designed Misso with bone movement monitoring to ensure safety during procedures. If bone movement is observed, the resection process stops. The resection will continue with automatic recovery of the bone position. If the robotic system’s tools contact the patient or other object, the collaborative robot arm will immediately stop moving.

Misso uses optical tracking-based navigation and robotic assistance to ensure accurate results in shaping and aligning artificial knee joint components. The company aims to improve post-operative outcomes, reduce complications, and promote faster patient recovery.

Meril joins the growing surgical robotics market and looks to compete with orthopedic surgical robot developers like Stryker and Zimmer Biomet. Stryker launched its next-gen Mako Total Knee surgical robotics platform in March 2023 after initially launching the total-knee platform in 2017. In February, Zimmer Biomet’s Rosa surgical robotic platform is cleared for shoulder and hip replacement procedures. The FDA also cleared it for partial knee replacement in April 2021."
