Challenge 

Today's most challenging arthroscopic procedures require power, speed and efficiency.

Portescap's autoclavable brushless DC motors are designed to provide high torque in a lightweight ergonomic package. Regardless of variations in patient tissue, bone or cartilage density, Portescap brushless DC motors will provide the power and speed needed to achieve exceptional surgical results. Additionally, our sterilizable brushless DC motors have shown to withstand in excess of 1,000 autoclave cycles, thus extending life and lowering end-customer total cost-of-ownership.

Benefits 

  • High-speed electric motors allow for shorter surgery cases and cleaner soft tissue cuts

  • High torque for increased surgeon control and device power

  • Sterilizable to 1,000+ autoclave cycles for increased instrument life and lower service cost

  • Lightweight and low vibration for increased surgeon tactile feel

  • High efficiency for smaller hand tool design and increased ergonomics

Customization Options 

  • Electrical magnetic coil customization to meet exact device torque and speed needs

  • Custom output shaft and housing interface features

  • High-level assembly integration

  • Alternative bearing material for increased operational life

  • Custom mechanical designs for added reliability
