Small Diameter Medical Grade Flexible Shafts

Suhner medical grade flexible shafts are offered in diameters from 0.024" to 0.500", made from stainless or high-carbon steels and can be provided with passivation, electropolishing or Teflon coating, as cleaned and fully assembled products, in OEM quantity.

Typical applications shown for Suhner medical grade flexible shafts.

Suhner Manufacturing, Inc. offers standard and custom flexible shafts for rotary power transmission on a variety of medical, orthopedic, endoscopic and laparoscopic instruments. In minimally invasive procedures, torsion stable rotary flexible shafts are vital for providing rotary motion on the surgical tool at the focal point of the work being performed. "To ensure the proper torsion and tactile feel on the distal end for the surgeon, Suhner flexible shafts offer torsional strength and minimal deflection with a uniformly smooth rotational behavior," said a company spokesperson.

These rotary flexible shafts are available with options such as passivation, electropolishing and Teflon coating and are provided as cleaned and assembled product, as needed, to suit the stringent applications of various medical procedures. Suhner medical grade flexible shafts are designed to provide precisely controlled rotary power transmission in a limited space. On one current application, a Suhner flexible shaft measuring only 0.024" diameter is in use for endoscopic surgeries. Other applications include endovascular aneurysm/aortic repair (EVAR) and thoracic endovascular (TEVAR) surgery, as well as stapling devices, orthopedic drills, surgical screwdrivers and laparoscopic devices.

Suhner rotary flexible shafts for medical instruments are available in clockwise, counterclockwise and bi-directional motion designs, in Type 302, 304, 316 and 17-7 stainless steel, as well as high-carbon steel, depending on the application. Suhner engineering can work with OEMs to devise functional solutions for specific instrument, tool and device applications alike. Medical grade rotary flexible shafts are available in various diameters from 0.024" to 0.500".
