I'm researching a coating for laproscopic instruments, specifically bipolar forceps or prongs used for tissue cutting. The tool is made up of three parts: scissors fixed on a cylindrical bar and end grips or bipolar forceps attached to the other end. Traditionally the instrument is made of stainless steel with PU coating on cylindrical bar. The objective is to prevent lateral propagation of electrothermal stresses generated by end grips or bipolar forceps. I am particulary looking at polymers like PVDF and Polyamides with further steps required to manufacture it economically. As the application is medical device , the coating needs to be biocompatible. I welcome your inputs. Thank You.
