摘要:
A surgical instrument includes a switch base, a power bus coupled to theswitch base, an electrical lead coupled to the power bus, an actuatoroperativelyengaged with the power bus, an actuator operatively engaged with the powerbus, amembrane, and a housing. The switch base has top, bottom, and side surfaces.Themembrane is disposed over the top surface of the switch base and over thepower busto seal the top surface of the switch base, The housing defines proximal anddistalends and a switch base cavity between the proximal and distal ends. Thehousingincludes bulkheads that form a plurality of fluid impermeable seals that aredisposedadjacent one of the proximal and distal ends. The fluid impermeable seals areconfigured to deter fluid from penetrating a proximal portion of the switchbase cavitywithin which the electrical lead is coupled to the power bus.
