Hand held electromechanical surgical handle assembly for use with surgical end effectors, and methods of use

摘要

The present disclosure relates to hand held electromechanical powered surgical handle assemblies for use with surgical end effectors capable of clamping, cutting and/or stapling tissue and methods of use thereof. The surgical device includes a handle assembly and a drive unit assembly removably and selectively connectable to a selected first connecting feature and second connecting feature of the handle assembly. The drive unit assembly includes a motor and a drive shaft driven by the motor.

主权项

1. A powered, hand held, electromechanical surgical device, comprising:
a handle assembly including:
a handle housing defining a longitudinal axis, the handle housing including a first connecting feature and a second connecting feature;a circuit board disposed within the handle housing;a battery disposed within the handle housing and being in electrical communication with the circuit board;at least one electrical contact associated with the first connecting feature of the handle housing and being in electrical communication with the circuit board and battery;at least one electrical contact associated with the second connecting feature of the handle housing and being in electrical communication with the circuit board and battery; andat least one first button for actuation by a finger of a user, each firing button being in electrical communication with the circuit board; and a drive unit assembly removably and selectively connectable to a selected one of the first connecting feature and the second connecting feature of the handle assembly, the drive unit assembly including:
a drive unit housing defining a longitudinal axis, the drive unit housing including a connecting feature configured and adapted to mate with a selected one of the first connecting feature and the second connecting feature of the handle assembly;a motor disposed within the drive unit housing;a drive shaft rotatably supported in and extending from the drive unit housing, the drive shaft being driven by the motor; andat least one electrical contact associated with the connecting feature of the drive unit housing and being in electrical communication with the motor; wherein, when the drive unit assembly is connected to the first connecting feature of the handle assembly:
an electrical contact associated with the connecting feature of the drive unit housing electrically interfaces with an electrical contact of the first connecting feature of the handle housing; andthe longitudinal axis of the drive unit assembly is parallel relative to the longitudinal axis of the handle housing; and wherein, when the drive unit assembly is connected to the second connecting feature of the handle assembly:
an electrical contact associated with the connecting feature of the drive unit housing electrically interfaces with an electrical contact of the second connecting feature of the handle housing; andthe longitudinal axis of the drive unit assembly is angled relative to the longitudinal axis of the handle housing.
