Power module for use with a surgical instrument
First Claim
1. A surgical instrument including an end effector and a power module, the power module comprising:
- a first motion conversion assembly, comprising;
a first rotary drive; and
a first axial drive operably coupled to the first rotary drive;
a second motion conversion assembly, comprising;
a second rotary drive; and
a second axial drive operably coupled to the second rotary drive;
a motor configured to generate at least one rotational motion to actuate the end effector, the motor defining an actuation axis; and
a transmission assembly configured to selectively operably couple the motor to the first rotary drive and the second rotary drive, wherein the first rotary drive is rotatable about the actuation axis in response to the at least one rotational motion when the motor is operably coupled to the first rotary drive, and wherein the second rotary drive is rotatable about the actuation axis in response to the at least one rotational motion when the motor is operably coupled to the second rotary drive.

Abstract
A surgical instrument, in at least one form, includes an end effector and a power module. The power module may include a first motion conversion assembly. The first motion conversion assembly includes a first rotary drive and a first axial drive operably coupled to the first rotary drive. The power module may further include a second motion conversion assembly which may include a second rotary drive and a second axial drive operably coupled to the second rotary drive. The power module may further include a motor configured to generate at least one rotational motion to actuate the end effector and a transmission assembly configured to selectively engage the motor with the first rotary drive and the second rotary drive, wherein the motor is concentrically arranged with the first rotary drive and the second rotary drive.

7. A surgical instrument, comprising:
-
a shaft; a housing extending proximally from the shaft; an end effector extending distally from the shaft; and a power module at least partially positioned within the housing, the power module comprising; a first rotary drive; a second rotary drive; a motor configured to generate at least one rotational motion, the motor defining an actuation axis; and a transmission assembly configured to selectively operably couple the motor to the first rotary drive and the second rotary drive, wherein the first rotary drive is rotatable about the actuation axis in response to the at least one rotational motion when the motor is operably coupled to the first rotary drive, wherein the second rotary drive is rotatable about the actuation axis in response to the at least one rotational motion when the motor is operably coupled to the second rotary drive, and wherein the motor extends along the actuation axis. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)
