Small Diameter Medical Grade Flexible Shafts Unveiled

Standard and custom flexible shafts for rotary power transmission on a variety of medical, orthopedic, endoscopic and laparoscopic instruments are now available, according to Suhner Manufacturing, Inc., Rome, GA.

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, the flexible shafts offer torsional strength and minimal deflection with a uniformly smooth rotational behavior.

The 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 provide precisely controlled rotary power transmission in a limited space. On one current application, a Suhner flexible shaft measuring 0.024 inches 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.  

The flexible shafts 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. 

Engineering assistance available to work with OEMs for specific instrument, tool and device applications, according to the company. Medical grade rotary flexible shafts are available in various diameters from 0.024 to 0.500 inches.
