'Wrist Trainer' for the practice of carpal tunnel injections and treatment of trigger finger in main case, by Limbs & Things Ltd, 1998.

The ‘Wrist Trainer’ is an artificial lower arm. It is made of synthetic rubber to simulate skin and connective tissue. It was used by medical students to practice surgical skills, specifically injections for conditions such as arthritis and carpal tunnel syndrome. Carpal tunnel syndrome is where the nerves in the wrist become compressed. The arm is attached to a feedback console. This illuminates various LED lights to indicate if the needle is correctly placed or if a nerve is hit.

Bristol-based company Limbs & Things Limited began manufacturing 3D synthetic limbs in 1990. This was in response to the rapid growth of small scale surgical operations undertaken by the NHS. Highly realistic models were needed for students and doctors to hone their skills before ever seeing a patient.
