Surgical forceps

A method of reusing an electrosurgical instrument, comprising:

• obtaining an electrosurgical instrument that has been used, the electrosurgical instrument including a plurality of reusable parts including a housing, a shaft, first and second jaw members each defining a tissue-contacting surface and a longitudinally-extending knife channel defined through each tissue-contacting surface, a movable handle, and a movable trigger, the electrosurgical instrument including at least one disposable part including a first knife blade, the shaft extending distally from the housing and supporting the first and second jaw members at a distal end thereof, the movable handle extending from the housing and operably coupling to the first and second jaw members to enable selective movement of at least one of the tissue-contacting surfaces relative to the other, the trigger extending from the housing and is operably coupling to the first knife blade, and the first knife blade, in the assembled state, configured for selective translation through the longitudinally-extending knife channels in response to actuation of the movable trigger;
• disassembling the at least one disposable part from the plurality of reusable parts;
• at least one of cleaning or sterilizing the plurality of reusable parts;
• discarding the at least one disposable part;
• obtaining a replacement part for each of the at least one disposable parts, wherein the replacement part for the first knife blade is a second knife blade;
• and
• reassembling the at least one replacement part with the plurality of reusable parts such that, in a reassembled state, the second knife blade is configured for selective translation through the longitudinally-extending knife channels in response to actuation of the movable trigger.
