Environment

Omniseal Solutions offers several different solutions and materials for the surgical handpiece market which includes orthopedic, dental, ophthalmology, plastic surgery, laparoscopic and general surgery. The market is broad and includes orthopedic hand drills, saws, burrs that are electric, pneumatic and battery-powered devices - all with unique needs. There are additional options including laser surgery, cryosurgery (liquid nitrogen) and ultrasonic energy powered devices.  Each of these handheld devices require custom design products to accommodate their unique properties and energy sources.

Although the surgical market continues to move to minimally invasive surgery where smaller devices are needed, other advancements such as higher power (RPMs) and lighter weight, precision handpieces are also critical.  

Challenge

Most handpieces require internal electronics protection during operation. Smaller seals and bearings for minimally invasive devices require smaller components that can be maintained at higher speeds. There are a wide range of speeds depending upon the application up to 400,000 rpms for dental and orthopedic drills from 1,000 to 100,000 rpms.  Some applications require longer running times than others so each surgical handpiece is unique and requires custom design and material.

Solution

Omniseal® spring-energized seals and O-Rings have material properties to protect internal electronics during operation. High speed surgical handheld devices need to be easy to handle and lightweight, which our team can provide in custom materials and designs including self-lubricating materials such as our Meldin® bearings. As the surgical market continues to move to minimally invasive surgery, custom, small Omniseal® parts continue to be a valuable engineering offer for innovative surgical and medical device designs.
