Electrosurgical device having a dielectric seal
View Patent ↗A method of manufacturing a seal in an electrosurgical device includes placing components of the electrosurgical device within an elongated housing section, the housing section including an actuator opening, introducing the housing section within a mold filled with a liquid thermoplastic elastomer and allowing the elastomer to flow within the housing, forming an elastomeric inwardly-extending lip portion circumferentially surrounding an opening at a distal end of the electrosurgical device for introducing an electrode therein, and allowing the molded elastomer to cure and become integral with the housing to seal the components within the molded elastomer contained within the housing section. The method may also include the step of forming an elastomeric actuator seal around the actuator opening.
1. A method of manufacturing a seal in an electrosurgical device, said method comprising the steps of:
placing components of the electrosurgical device within an elongated housing section, said housing section including an actuator opening;
introducing the housing section within a mold filled with a liquid thermoplastic elastomer and allowing the elastomer to flow within the housing;
forming an elastomeric inwardly-extending lip portion circumferentially surrounding an opening at a distal end of the electrosurgical device for introducing an electrode therein; and
allowing the molded elastomer to cure and become integral with the housing to seal the components within the molded elastomer contained within the housing section.
2. The method of claim 1 , further comprising the step of forming an elastomeric actuator seal around the actuator opening.
3. The method of claim 2 , further comprising the step of insert molding two inserts within the actuator seal to identify the culling and coagulating modes.
