CONDUCTOR ARRANGEMENTS FOR ELECTRICALLY POWERED SURGICAL INSTRUMENTS WITH ROTATABLE END EFFECTORS

摘要

A surgical instrument that includes a housing (12) that has an elongated shaft assembly (16) attached thereto that is configured to be rotated relative to the housing. The surgical instrument further includes a conductor arrangement (930, 932, 936, 944) that facilitates transfer of electrical power or current from a power source (200) which may be located in the housing or external to the housing to a distal portion of the elongated shaft assembly or to a surgical end effector coupled thereto. The surgical instrument may further include a travel limiting arrangement (950) for limiting the amount of rotary travel of the elongated shaft assembly relative to the housing to a predetermined range of rotary travel.
