MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202641025476 A) filed by Meenakshi Academy Of Higher Education And Research; and Meenakshi Ammal Dental College And Hospital, Chennai, Tamil Nadu, on March 4, for 'a precision-controlled instrument for uniform cartilage graft slicing with adjustable micrometric thickness.'
Inventor(s) include Shubham Kumar; Dr. Anantanarayanan Parameswaran; and Dr. Deepanjali Megarasu.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a precision-controlled graft slicing instrument for preparing uniform cartilage graft slices of controlled and reproducible thickness for use in oral and maxillofacial, plastic, and reconstructive surgical procedures. The instrument comprises a stable platform fabricated from medical-grade stainless steel, a sliding tray configured for guided linear movement, a cutting blade positioned above the sliding tray, an adjustable thickness-control mechanism operatively connected to the cutting blade, and a graft-holding component comprising multiple short penetrating needles configured to immobilize the graft during slicing. The thickness-control mechanism includes a micrometric adjustment knob enabling precise regulation of blade height relative to the sliding tray to achieve reproducible graft thickness. The coordinated interaction of the platform, sliding tray, cutting blade, thickness-control mechanism, and graft-holding component enables controlled, stable, and repeatable slicing of cartilage grafts with reduced operator-dependent variability and minimized risk of tissue deformation or damage. The instrument is suitable for use in surgical and training environments and is compatible with standard sterilization procedures."
