Publication number: 20210386424Abstract: A surgical stapling apparatus includes a housing assembly and an elongated shaft assembly. The elongated shaft assembly is selectively attachable to the housing assembly. The elongated shaft assembly includes an adapter assembly and a loading unit. The adapter assembly extends distally to a distal tip housing. The distal tip housing supports an adapter electrical connector assembly therein. The loading unit is selectively attachable to the adapter assembly and extends distally to an end effector supporting one or more sensors therein. The loading unit supports a loading unit electrical connector assembly therein. The loading unit electrical connector assembly is positioned to contact the adapter electrical connector assembly when the adapter assembly and the loading unit are coupled together to electrically couple the one or more sensors to the housing assembly.Type: ApplicationFiled: May 17, 2021Publication date: December 16, 2021Inventors: Pawel Abramek, Kenneth H.

Patent number: 10292705Abstract: A surgical apparatus includes a handle, an elongate member and a switch actuator. The switch actuator includes an activation link and a switch plunger coupled to the activation link. An electric switch is mounted to the elongate member. A rotatable lock member is mounted to the elongate member and adapted for rotational movement between an unlocked condition and a locked condition. The rotatable lock member includes an actuator stop dimensioned to operatively engage the switch actuator to prevent movement of the switch actuator from a first longitudinal position to a second longitudinal position when in the unlocked condition, and to permit movement of the switch actuator to the second longitudinal position when rotated to the locked condition such that the switch plunger activates the switch. A loading unit is releasably couplable to the rotatable lock member and is secured relative to the elongate member when the rotatable lock member is in the locked condition.Type: GrantFiled: October 13, 2016Date of Patent: May 21, 2019Assignee: Covidien LPInventors: David Chowaniec, Pawel Abramek, David Fowler, Matthew D'errico
