1. A transmission for a surgical tool, the transmission comprising:
- a housing;
a first gear disposed within the housing, the first gear being configured to actuate a first function of the surgical tool;
a second gear disposed within the housing, the second gear being configured to actuate a second function of the surgical tool;
a third gear disposed within the housing, the third gear being configured to actuate a third function of the surgical tool;
a first rotatable input shaft disposed at least partially within the housing;
a second rotatable input shaft disposed at least partially within the housing, the second rotatable input shaft configured to rotate between a first position, a second position, and a third position,when the second rotatable input shaft is in the first position, the first gear is operatively engaged with the first rotatable input shaft such that rotation of the first rotatable input shaft causes rotation of the first gear to actuate the first function of the surgical tool,when the second rotatable input shaft is in the second position, the second gear is operatively engaged with the first rotatable input shaft such that rotation of the first rotatable input shaft causes rotation of the second gear to actuate the second function of the surgical tool, andwhen the second rotatable input shaft is in the third position, the third gear is operatively engaged with the first rotatable input shaft such that rotation of the first rotatable input shaft causes rotation of the third gear to actuate the third function of the surgical tool;
one of the first function, the second function, and the third function comprising rotation of an end effector of the surgical tool; and
a different one of the first function, the second function, and the third function comprising pivoting of a first jaw of the end effector relative to a second jaw of the end effector.

Abstract
A surgical instrument including a housing, an endoscopic portion, a shaft portion, and an end effector is disclosed. The endoscopic portion extends distally from the housing and defines a longitudinal axis. The shaft portion is selectively connectable to a distal end of the endoscopic portion. The end effector is selectively connectable to a distal end of the shaft portion.

16. A surgical tool, comprising:
-
a housing; a shaft comprising a proximal end and a distal end, the proximal end of the shaft being connected to the housing; an end effector connected to the distal end of the shaft, the end effector comprising a first jaw and a second jaw, at least one of the first jaw and the second jaw being configured to pivot relative to each other; a transmission at least partially disposed within the housing, the transmission being shiftable between a first configuration, a second configuration, and a third configuration, the transmission comprising; a first input configured to actuate a first function of the surgical tool when the transmission is in the first configuration, to actuate a second function of the surgical tool when the transmission is in the second configuration, and to actuate a third function of the surgical tool when the transmission is in the third configuration; a second input configured to shift the transmission between the first configuration, the second configuration, and the third configuration; one of the first function, the second function, and the third function comprising rotation of the shaft of the surgical tool; and a different one of the first function, the second function, and the third function comprising pivoting at least one of the first jaw and the second jaw of the end effector relative to each other. - View Dependent Claims (17, 18, 19, 20)
