1. A ureteroscope comprising:
a housing having a proximal end and a distal end;
a compressible chamber composed of a flexible material and coupled to an outer surface of the housing, the compressible chamber having an inlet arranged adjacent the proximal end of the housing and an outlet arranged adjacent the distal end of the housing, wherein the inlet is configured to receive fluid and communicate the fluid into the compressible chamber;
a working channel coupled to the distal end of the housing and in fluid communication with the outlet of the compressible chamber, wherein the working channel is axially aligned with the outlet of the compressible chamber, wherein the working channel includes an interior volume configured to receive a surgical instrument;
a flexible tube coupled to the distal end of the housing that contains the working channel; and
a port disposed on an exterior of the housing, distal from the compressible chamber, and configured to receive the surgical instrument for insertion of the surgical instrument through the working channel from the housing through the flexible tube;
wherein when the compressible chamber is compressed, the fluid contained in the compressible chamber is forced out of the compressible chamber through the outlet and into the interior volume of the working channel.
