Battery powered surgical instrument
First Claim
1. A powered endoscopic surgical apparatus, comprising:
- a handle including a housing and a power source supported in the housing;
an endoscopic portion extending distally from the housing of the handle;
an end effector assembly coupled to a distal end portion of the endoscopic portion, the end effector assembly including a pair of jaws configured to perform a surgical function, at least one of the jaws being movable with respect to the other jaw;
a driving member extending between the handle and the end effector assembly, the driving member configured to translate along a drive path thereof to selectively actuate the end effector assembly;
a motor powered by the power source and connected to the driving member such that the driving member is translated along the drive path upon actuation of the motor;
a sensor disposed along the drive path of the driving member;
a graphical display supported in the housing and operatively coupled to the sensor, the graphical display configured to receive a first signal from the sensor corresponding to a location of the driving member along the drive path and display a visual indication corresponding to the location of the driving member along the drive path; and
a controller operatively coupled to the sensor and the motor, the controller configured to modulate the motor upon receiving a second signal from the sensor corresponding to the location of the driving member along the drive path.

Abstract
A powered endoscopic surgical apparatus is provided and includes a handle including a housing, a power source supported in the housing; an endoscopic portion extending distally from the housing of the handle; an end effector assembly coupled to a distal end of the endoscopic portion, the end effector assembly including a pair of jaws configured to perform a surgical function; a driving member; a drive source including a motor powered by the power source and connected to the driving member; and a gear assembly engaged with the motor. The gear assembly including a gear rack provided on the driving member; and a main gear operatively connected with the gear rack, the motor spinning the main gear such that rotary motion of the main gear moves the driving member in an axial direction such that the driving member actuates the end effector to perform the surgical function.
