Abstract

A hand-held electromechanical surgical device configured to selectively connect with a surgical accessory, is provided and includes a handle assembly having a power pack with a core assembly. The core assembly includes a plurality of motors, with each motor having a rotatable drive shaft extending therefrom, wherein each drive shaft is parallel to one another; a processor connected to and configured to control each motor; and a battery electrically connected to the processor and each motor. The power pack includes an inner housing encasing at least the plurality of motors, the processor, and the battery. The handle assembly includes an outer shell housing configured to selectively encase substantially the entire power pack therein, wherein a rotation from each rotatable drive shaft of each motor is transmitted through the inner housing and the outer shell housing.

Dependent claims

A hand-held electromechanical surgical device configured to selectively connect with a surgical accessory, the electromechanical surgical device, comprising:

a handle assembly including:
a power pack including:
a core assembly having:
a plurality of motors, with each motor having a rotatable drive shaft extending therefrom, wherein each drive shaft is parallel to one another;
a processor connected to and configured to control each motor;
and
a battery electrically connected to the processor and each motor;
and
an inner housing encasing at least the plurality of motors, the processor, and the battery, the inner housing including at least one control interface actuatable to control a functionality of at least one of the plurality of motors;
an outer shell housing configured to selectively encase substantially the entire power pack therein, wherein a rotation from each rotatable drive shaft of each motor is transmitted through the inner housing and the outer shell housing, and wherein the outer shell housing includes at least one control button in operative registration with each control interface of the power pack;
wherein actuation of the at least one control button acts on the at least one control interface that is in operative registration therewith to control the functionality of the at least one of the plurality of motors.
