Claim 0:
1. A tissue resecting system, comprising:
a first portion, including:
a body defining a fluid path, a first section of the fluid path extending through the body;
a rotating hub rotatably disposed within the body, the rotating hub defining a second section of the fluid path in fluid communication with the first section of the fluid path;
a seal disposed on the rotating hub; and
an elongated assembly extending distally from the body, the elongated assembly including a shaft and a cutting element disposed within the shaft, the cutting element operably coupled to the rotating hub, wherein an internal flow channel extends longitudinally through the elongated assembly and fluidly communicates with the second section of the fluid path, thereby establishing fluid communication from the internal flow channel to the first section of the fluid path;

a second portion configured to detachably couple to the first portion, the second portion including:
a case detachably coupled to the body of the first portion, the case defining an internal volume; and
an electric motor partially disposed within the internal volume of the case, the electric motor defining a hub drive shaft that protrudes through the case of the second portion, the hub drive shaft configured to extend into direct engagement with the rotating hub when the case is coupled to the body of the first portion to enable actuation of the cutting element with the electric motor, wherein the seal fluidly isolates the fluid path from the hub drive shaft when the case is coupled to the body;

an endoscope configured to be inserted into an organ, the endoscope including a working channel defining an inflow passageway, wherein the elongated assembly of the first portion is configured to telescope through the working channel;
a pump fluidly coupled to the fluid path, the internal flow channel, and the inflow passageway of the endoscope, wherein the pump is configured to draw fluid and tissue through the internal flow channel and the fluid path; and
a filter fluidly coupled between the internal flow channel and the inflow passageway, the filter configured to remove tissue from fluid.
