1. A tissue resecting device, comprising:
a handle;
an elongate shaft extending from the handle, the elongate shaft including an outer sleeve and a reciprocating inner resecting sleeve disposed in the outer sleeve, wherein such reciprocation of the inner resecting sleeve moves a distal end of the inner resecting sleeve across a tissue-receiving window of the outer sleeve between window-open and window-closed positions;
a motor drive in the handle;
an actuator in the handle coupled between the motor drive and the inner resecting sleeve to convert rotational motion from the motor drive to linear reciprocation motion of the inner resecting sleeve relative to the outer sleeve for reciprocating the inner resecting sleeve; and
a drive shaft coupled to the actuator;
wherein the actuator converts rotational motion from the motor drive to linear reciprocation motion of the drive shaft such that the drive shaft translates axially relative to the handle;
wherein linear reciprocation motion of the drive shaft is transferred to the inner resecting sleeve via a coupling arm spaced apart from the actuator;
wherein the inner resecting sleeve extends proximal of the actuator and reciprocates relative thereto.
