A Bulldog Shuttle Lock is an advanced suspension system used in modern prosthetic legs to provide strong and reliable attachment between the residual limb and the prosthetic socket. It works with a silicone or gel liner that has a locking pin, which securely clicks into the lock mechanism inside the socket. This design prevents slipping and gives amputees confidence while walking, standing, or performing daily activities. Many systems use ball-bearing technology to hold the pin firmly and reduce wear. In the Indian prosthetic market, the Bulldog shuttle lock is popular because of its durability, safety, and easy push-button release system. It offers comfort, stability, and smooth suspension, making it suitable for active prosthetic users.
