Portescap has released three new surgical motors designed for orthopaedic saws, drills and reamers. The compact motors aim to offer controllable, precise torque and have been tested to withstand 1,000+ sterilisation cycles.

Orthopaedic surgery treats a range of musculoskeletal conditions arising from trauma, sport injury, bone diseases, degenerative diseases, infections etc. Where procedures are performed on small bones - such as vertebrates or those found in the radiocarpal or talocrural joints – precision is key with every action. The surgical tools used need to deliver power in a smooth and controllable manner to ensure a positive outcome for the patient.

Portescap’s latest additions have been designed specifically with small bone orthopaedic applications in mind.

The B0912N1016 Small Bone Motor (9.6 V - 38K rpm), B0912N4023 Small Bone Gearmotor (9.6 V - 1.1K rpm), and B0912N4024 Small Bone Gearmotor (9.6 V - 12.8K rpm) are sterilisable brushless DC (BLDC) motors for drills, saws and reamers. They can be used for surgical tools - in addition to robotically assisted surgical devices - and can be paired with a Portescap sterilisable controller for battery powered applications.

The motors deliver high peak torque capable of powering through the densest bones and feature customisable voltage to accommodate precise control for the surgeon. The 22 mm diameter motors are lightweight and produce low noise and vibration to improve the ergonomic comfort and control in the hand – essential in long surgeries where fatigue may set in. To ensure reliability and cost efficiency the motors have all been tested to withstand 1,000+ sterilisation cycles as well as exposure to saline and other foreign materials.
