초록 ▼

A method for manufacturing a jaw assembly configured for use with an electrosurgical forceps is provided. A seal plate with an inwardly facing tab member extending along a peripheral edge thereof is formed. A cavity defined along the inwardly facing tab member of the seal plate is formed. Subsequently, the seal plate is overmolded to a jaw housing. The cavity is configured to receive an insulative substrate therein to facilitate securing the seal plate to the jaw housing.

대표청구항 ▼

1. A method for manufacturing a jaw member configured for use with an electrosurgical forceps, comprising: forming a seal plate defining a central longitudinal axis and a sealing surface;forming a cavity opposite the sealing surface by bending a peripheral edge of the seal plate substantially perpendicular to the sealing surface to define a tab and bending a portion of the tab toward the longitudinal axis substantially parallel to the sealing surface, wherein forming the cavity includes forming the cavity between the tab and another portion of the seal plate; andsecuring the seal plate to a jaw housing by receiving an insulative substrate within the cavity during an overmolding process to form the jaw member configured for use with an electrosurgical forceps. 2. The method according to claim 1, wherein forming the seal plate includes forming at least one aperture thereon. 3. The method according to claim 2, wherein the at least one aperture is configured to receive the insulative substrate therein such that during the overmolding process of the jaw housing an insulative stop member is formed on the seal plate. 4. The method according to claim 3, wherein the insulative stop member includes a generally arcuate configuration. 5. The method according to claim 1, further comprising welding a wire to the seal plate. 6. The method according to claim 1, wherein the insulative substrate is made from plastic. 7. A method for manufacturing jaw members configured for use with an electrosurgical forceps, comprising: stamping at least one pair of seal plates from sheet metal, each of the seal plates defining a central longitudinal axis and a sealing surface;forming, on each of the seal plates, a cavity opposite the sealing surface by bending a peripheral edge of each of the seal plates substantially perpendicular to the sealing surface to define a tab and bending a portion of the tab toward the central longitudinal axis substantially parallel to the sealing surface, wherein forming the cavity includes forming the cavity between the tab and another portion of the seal plate;positioning the seal plates into respective mold cavities;introducing an insulative substrate into the respective mold cavities such that the insulative substrate is received within the respective formed cavity;allowing the insulative substrate to harden in the respective mold cavities to form respective jaw housings with respective seal plates secured thereto, wherein the respective formed cavity is configured to receive the insulative substrate therein to facilitate securing the respective seal plate to the respective jaw housing; andremoving the jaw housings from the respective mold cavities to form at least a pair of jaw members configured for use with an electrosurgical forceps. 8. The method according to claim 7, wherein forming the seal plates includes forming at least one aperture thereon. 9. The method according to claim 8, wherein the at least one aperture is configured to receive the insulative substrate therein such that during an overmolding process of the respective jaw housing an insulative stop member is formed on the seal plate. 10. The method according to claim 9, wherein the insulative stop member includes a generally arcuate configuration. 11. The method according to claim 7, further comprising welding a wire to each of the seal plates. 12. The method according to claim 7, wherein the insulative substrate is made from plastic. 13. A method for manufacturing jaw members configured for use with an electrosurgical forceps, comprising: stamping at least one pair of seal plates from sheet metal, each of the seal plates defining a central longitudinal axis and a sealing surface;forming, on each of the seal plates, a cavity opposite the sealing surface by bending a peripheral edge of each of the seal plates substantially perpendicular to the sealing surface to define a tab and bending a portion of the tab toward the central longitudinal axis substantially parallel to the surface, wherein forming the cavity includes forming the cavity between the tab and another portion of the seal plate;positioning the seal plates into respective mold cavities;introducing an insulative substrate into each of the respective mold cavities such that the insulative substrate is received within the respective formed cavity;allowing the insulative substrate to harden in the respective mold cavities to form respective jaw housings with respective seal plates secured thereto, wherein each formed cavity is configured to receive the insulative substrate therein to facilitate securing the respective seal plates to the respective jaw housings, and wherein the at least one aperture is configured to receive the insulative substrate therein such that an insulative stop member is formed on the seal plate; andremoving the jaw housings from the respective mold cavities to form a pair of jaw members configured for use with an electrosurgical forceps.
