1. A kidney stone removal mechanism comprising:
an irrigation tube configured to transport a volume of an irrigation fluid supplied through an inlet, the irrigation tube having a portion passing within and contactable with a trigger mechanism through which a first amount of the volume of the irrigation fluid passes; and
a bypass structure connected at only two places with the irrigation tube and configured to receive a second amount of the volume of the irrigation fluid and to allow the second amount of the volume of the irrigation fluid to be transported through a first part of the irrigation tube and transferred through a second part of the irrigation tube to be discharged from an outlet without any of the second amount of the volume of the irrigation fluid passing through the portion of the irrigation tube passing within and contactable with the trigger mechanism,
wherein the first amount of the volume of irrigation fluid bypasses the bypass structure; and
wherein the trigger mechanism includes a trigger operable by a user, the trigger mechanism operable to selectively constrict, close, and open the irrigation tube to irrigate an area of treatment upon user operation of the trigger.
