Motors player launches brushless products for arthroscopic applications

Motor products provider Portescap has launched cannulated size six brushless slotted DC motors for arthroscopic applications.

For arthroscopic shavers in particular - where variations in patient tissue, bone and cartilage density must be considered - the right combination of speed and power is required to remove soft tissue and bone. Motors need to be tightly packaged and offer minimal vibration to achieve lightweight, ergonomic designs.

The release of three new cannulated surgical motors for arthroscopic applications aims to offer engineers a solution with low vibration, high efficiency and a proven ability to withstand 1,000+ sterilisation cycles – as well as exposure to saline and other foreign materials.

The B0612H1005 Cannulated Microdebrider / Shaver Motor (48V), B0612H1006 Cannulated Microdebrider / Shaver Motor (36V) and B0612H1007 Cannulated Microdebrider / Shaver Motor (24V) are sterilisable BLDC motors designed for arthroscopic shaver and microdebrider applications. Each has been optimised for a specified input voltage to provide the torque and speed that is typically required to effectively remove soft tissue and bone in minimally invasive surgical procedures.

The popularity of arthroscopy as an alternative to open surgery is a result of the overwhelming evidence that the minimally invasive technique reduces recovery rates and may increase the rate of successful surgeries. The challenge for engineers designing surgical tools for arthroscopic applications is to specify components that deliver the highest levels of control, reliability and consistency.

The new Portescap motors are lightweight with low noise and vibration to maximise tactile response and surgeon control in the most delicate of surgeries.
