MANUFACTURING ELECTROSURGICAL INSTRUMENTS

摘要

A jaw member for an electrosurgical instrument is manufactured by providing a jaw housing (1) having a longitudinal jaw section (2), and an electrically conductive plate (11) including one or more passages (14) therein. The electrically conductive plate is disposed on the jaw section of the jaw housing, and placed into a mould (15). A flowable insulating material (18) is injected into the mould to secure the electrically conductive plate to the jaw housing, such that the flowable material (18) flows through the one or more passages (14) to form one or more stop members (21) that project a predetermined distance from the electrically conductive plate.

1. A method for manufacturing a jaw member for an electrosurgical instrument, comprising the steps of:
providing a jaw housing having a longitudinal jaw section; providing an electrically conductive plate including one or more passages therethrough; disposing the electrically conductive plate on the jaw section of the jaw housing; placing the jaw housing and the electrically conductive plate into a mould; injecting a flowable insulating material into the mould to secure the electrically conductive plate to the jaw housing, such that the flowable material flows through the one or more passages to form one or more stop members that project a predetermined distance from the electrically conductive plate; allowing the flowable insulating material to solidify; and removing the jaw housing, electrically conductive plate and the solidified insulating material from the mould as a jaw member.
