SS Innovations International has completed the development of five new 5mm surgical instruments for clinical use with its SSi Mantra system in procedures involving smaller anatomical structures.

The newly developed 5mm surgical instruments include a spatula cautery, hook cautery, needle driver, bipolar forceps, and grasping forceps.

Vishwa Srivastava, the company’s chief executive officer for Asia Pacific, commented: “Our 5mm instruments can benefit cardiac surgery, which often involves small structures, such as the internal mammary artery during robotic coronary artery bypass surgery. Furthermore, our new robotic instruments can help perform critical tasks during head and neck procedures, which entail tight working space and quite small structures. Moving forward, we will continue to focus on developing differentiated surgical robotic technologies, such as these instruments, for the benefit of a larger segment of patients globally.”

As of 31 December 2025, the cumulative installed base of the SSi Mantra totalled 168 systems, including 12 systems deployed across nine countries outside of India. To date, 153 hospitals have installed the SSi Mantra, and more than 7,800 surgical procedures have been performed, including over 120 telesurgeries and more than 400 cardiac procedures.
