Micro-motion solutions for powered hand tools used in large bone procedure

Problem and background

Surgeries for knee and shoulder replacement are very common and increasingly prevalent due to the aging population and the rise of degenerative joint conditions like Osteoarthritis. On these surgeries, the surgeon removes the damaged joints, replacing them with artificial implants. These procedures become necessary when alternative treatments no longer provide relief and the joint's function significantly deteriorates.

Surgical reamers and saws are very common types of tools used for these procedures with engineered designs to aid the surgeon and minimize the duration of the operation. Essential to these tools is their high torque characteristic to handle large and hard bone density.

Application Highlights: Large Bone Orthopedic Surgical Tools

Orthopedic surgeries, such as those involving the knee, hip, shoulder, and large bones, demand motion precision and light weight tools for smooth, one-handed control. Also, critical to these applications is the ruggedness of the tool and its internal components to withstand repeated sterilization cycles and exposure to saline solutions.

Solution

The requirements of high torque surgical tools are perfectly suited for Portescap's Surgical Motor Solutions product line. Our slotted brushless DC motors feature exceptional torque enabling surgeons to operate on the toughest bones with the smallest motor possible.

•	Increased instrument life and lower service cost (products designed to withstand over 3,000+ autoclave cycles)
•	Lightweight and low vibration for increased surgeon tactile feel and reduced fatigue
•	High efficiency for smaller hand tool design and increased ergonomics/battery life
•	Cannulated designs that enable passage of pins through the motor for pin-driving, and wire-driving / K-wire applications
•	Optimization / customization
