MUMBAI, India, Aug. 31 -- Intellectual Property India has published a patent application (202611054465 A) filed by Dr. N V Adithya Nair; Dr. Rajiv Ahluwalia; Dr. Tina Chugh; and Santosh Deemed To Be University on April 29, 2026, for An Orthodontic Pin And Ligature Cutting Instrument Having Replaceable Cutting Inserts.
Inventors include Dr. N V Adithya Nair; Dr. Rajiv Ahluwalia; and Dr. Tina Chugh.
The application for the patent was published on August 28, 2026, under issue no. 35/2026.
Abstract: The present invention relates to an improved orthodontic cutting instrument, specifically a pin and ligature cutter with replaceable cutting inserts. The cutter comprises two handles pivotally connected by a pivot joint and two opposing jaws terminating in a cutting head region. Each jaw is provided with a superiorly positioned receiving slot configured to removably accommodate a hardened cutting insert having a sharpened cutting edge. Two opposing inserts together form a double-edge cutting interface for cutting orthodontic ligature wires, pins, and auxiliary metallic components. The inserts are retained within the receiving slots through frictional engagement, press-fit retention, and geometric interlocking features such as dovetail or stepped configurations, enabling resistance to torsional, shear, and compressive forces encountered during clinical use. The modular design permits selective replacement of worn cutting edges while reusing the instrument body, thereby extending instrument lifespan, reducing cost, and minimizing biomedical waste.
