Description

Endoscopic Sheaths/Outer Working Channels.

Description: This is a set of rigid, metallic sheaths, likely manufactured by Richard Wolf (a major endoscopy equipment company), used in conjunction with a rigid endoscope (like a cystoscope or ureteroscope).

Function: The sheath acts as the external working channel and conduit for the endoscope and other instruments.

Features: Each sheath has a side port with a stopcock (the metallic part with the small knob) for continuous irrigation or suction flow. The yellow plastic caps may indicate that the sheaths are sterile and unused, or they could be protective tips. The variety in length/diameter (suggested by the labels) is necessary for different patient sizes and procedural requirements.
