Portescap introduces the B2010A4 and B0810A1 brushless DC slotted motors as its two newest additions to their Surgical Motor Solutions portfolio. Leveraging Portescap’s expertise in developing sterilizable solutions for surgical hand tool applications, these motors are designed to withstand more than 1,000 autoclave and medical device dishwasher cycles. This is possible due to the improved encapsulation of the windings, which enhances the motors’ autoclavability.
The B2010A4 (Size 20) bone mill surgical gearmotor features a 50mm diameter, which is unique as such a sterilizable motor in such a large frame size. The motor’s 6 poles and full metal gearhead allows it to achieve a high peak torque of 15Nm while simultaneously providing a continuous, slow rotation for bone mill and bone crusher devices.
Design flexibility in the surgical application space
With a 20mm frame size, the B0810A1 (Size 8) multi-tools surgical motor fills the gap between Portescap’s existing Size 6 and Size 9 SMS motors, making it an ideal choice for device miniaturization. The 4-pole design enables the Size 8 to provide 20% more torque than competitive solutions within the same package size, and its lightweight mass of 110 grams facilitates longer working times for surgical hand tools and decreased surgeon fatigue.
Both the B2010A4 and B0810A1 provide much-needed design flexibility for those within the surgical application space. As its name would suggest, the Size 20 is an ideal choice for bone mill surgical devices, while the Size 8 excels in liposuction, skin grafting, and small bone drill applications.
