A modular endoscope valve assembly (30) is releasably mounted on the handpiece (12) of an endoscope (10). This valve assembly includes an inlet port (32), an outle port (34), and a valve (36) manually operable selectively to block and to allow the flow of irrigation fluid from the inlet port to the outlet port. The valve assembly is releasably held to the handpiece (12) of the endoscope (10) by a mechanical fastener such as a pressure-sensitive adhesive (40), a strap (42), a snap lock, or otherwise. Once the valve assembly (30) is releasably mounted to the handpiece, the physician using the endoscope can manually control the flow of irrigation fluid, and optionally suction, with the same hand as the one that supports the handpiece, thereby leaving the other hand of the physician free for surgical procedures. The modular valve assembly (30) of this invention can be used with the widest variety of endoscopes, including flexible, rigid and semi rigid ureteroscope as well as various percutaneous endoscopes. |
