Abstract
A tissue resecting device includes a handpiece assembly and an end effector assembly. The handpiece assembly includes a motor and a cooling assembly. The cooling assembly includes a housing, a fan assembly, and a fin pack. The fan assembly includes a tubular member configured to be received in the elongate cover, and a plurality of blades rotatably supported on the tubular member and operatively coupled with a drive rotor of the motor for concomitant rotation therewith. The fin pack includes a tubular base and a plurality of fins extending radially outward from the tubular base. The tubular base is disposed within the elongate cover and about the tubular member of the fan assembly. Actuation of the motor rotates the plurality of blades of the fan assembly to thereby advance air through a space between the fin pack and the elongate cover of the housing to facilitate cooling of the motor.
