Method for sealing a reusable electrical surgical instrument

摘要

A method for sealing surgical instruments, particularly reusable electric surgical instruments sterilized using an autoclave process, is disclosed. The method having the steps of providing at least two body shells having a runner system on the mating surfaces, aligning the body shells, securing the body shells in position relative to each other, inserting an injection device into the runner system, injecting an elastomer material from the injection device into the runner system, removing the injection device from the runner system, and curing the elastomer material. The elastomer material seals the housing chamber of the instrument. The elastomer material may bond the body shells together.

1. A method for assembling and sealing a reusable electrical surgical instrument, comprising:
providing at least two body shells of an instrument, each body shell having at least one joining surface, where a pair of mutual joining surfaces is defined by the joining surface one body shell that is configured to mate with the joining surface of a second body shell, at least one joining surface of the pair of mutual joining surfaces having a runner system surrounding the perimeter substantially near the edge, the runner system having an inlet port and an outlet port connected by a bridge section; aligning the pair of mutual joining surfaces; securing the body shells in position relative to each other; inserting an injection device into the inlet port past the bridge section; injecting an elastomer material from the injection device through the inlet port until the elastomer material exits from the outlet port; removing the injection device from the inlet port while continuing to inject elastomer material from the injection device; and curing the elastomer material forming a seal along the pair of mutual joining surfaces.
