ABSTRACT:
Improved electrocautery instruments, particularly instruments better adapted for manufacture at lower costs, are disclosed including an electrocautery hemostat comprised of a hemostat provided with clam shell synthetic plastic handles with a switch incorporated therein. The mirror image plastic clam shells are mounted over the handle portion of the instrument and bonded together, preferably by sonically welding. Other embodiments include an instrument wherein a substantial or major portion of the instrument, particularly a handle portion, is comprised of a rigid synthetic plastic material with means for connecting switched RF energy to the metal tissue engaging tips. And still another embodiment of the invention, a switch mounted on a rigid conductive hemostat is provided with a switch mounted thereon and insulated from the surgeon's hand by an insulative coating, such as latex.
