MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202521132717 A) filed by Pathak, Smita; and Saha, Anyesha, Bhopal, Madhya Pradesh, on Dec. 28, 2025, for 'a tenodesis wrist-hand orthosis with enhanced functional grip mechanism.'
Inventor(s) include Pathak, Smita; and Saha, Anyesha.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention is related to a tenodesis wrist-hand orthosis with enhanced functional grip mechanism. This tenodesis wrist-hand orthosis (WHO) designed to enhance functional grasp in individuals with impaired hand function, such as those with cervical-level spinal cord injuries or neuromuscular disorders. The orthosis comprises a dorsal finger plate (101), a wrist band (102), a short opponens component (103), and an elastic lacer (104) that transfers mechanical force from wrist extension to finger flexion. When the wrist extends, the elastic lacer flexes the fingers, enabling a natural tenodesis grasp, while wrist flexion releases the tension to allow hand opening. The biomechanics of the device are optimized using lever lengths (201, 202) and torque transfer principles (203, 204, 205), assisted by active extensor carpi radialis brevis (206) and taut flexor digitorum profundus and flexor pollicis longus (207). The orthosis is lightweight, low-profile, adjustable, and cost-effective to fabricate, improving comfort, ease of donning/doffing, and independence in activities of daily living, offering technical advantages over existing tenodesis splints."
