Abstract
The cutting instrument of this invention is made by threading a heater assembly through a hollow cutting instrument body. A blade having a shank and a blade body including a cutting edge is secured within the hollow cutting instrument body at its shank portion such that the blade body extends from the hollow cutting instrument body. The heating assembly is secured to the blade body and to the cutting instrument body. The blade body is coated with a non-stick means.
Claims12
A method for manufacturing a cutting instrument having a hollow instrument body with proximal and distal ends, a blade body with a shank section and a cutting edge section, and a heater assembly with proximal and distal portions integrally fabricated from an electrically-conductive strip material, said method comprising the steps of:
- passing the distal portion of the heater assembly through the hollow instrument body;
- wrapping the distal portion of the heater assembly around the distal end of the hollow instrument body to establish an electrical contact;
- securing the shank section of the blade body to the proximal end of the hollow instrument body such that the cutting edge section of the blade body extends from the proximal end of the hollow instrument body;
- and
- laminating the proximal portion of the heater assembly to the blade body such that the heater assembly is electrically insulated from but in good thermal communication with the blade body and such that direct electrical connection is maintained between said electrical contact established at the distal end of the hollow instrument body and the proximal portion of the heater assembly.
