Patent ID: 8876705

Claim:
A medical endoscope including a control handle provided with a control mechanism and that, by means of an attachment system, is temporarily attached to a consumable medical instrument including: at least one flow circuit for a fluid, a portion of which circuit extends along an insertion tube, the fluid circuit including a connector fitting accessible independently from the handle; and an actuation system for actuating the head of the insertion tube, which actuation system is driven by the control mechanism after the handle and the consumable medical instrument have been attached together; said medical endoscope being characterized in that the control handle and the consumable medical instrument, respectively, have a first portion and a second portion of a closure device, which portions co-operate with each other in the attached position to close off at least one fluid flow circuit in a controlled manner; wherein the first portion is formed by a deformable portion of the flow circuit that is not closed off prior to attachment, between the control handle and the consumable medical instrument; and the second portion comprises a clamp, acting after attachment and on the deformable portion of the flow circuit in order to close off the flow circuit automatically, and caused to move by a control button for controlling closure of said circuit; wherein the clamp is carried by a slidably mounted pin that projects from the support to form a control button, making it possible to control closure of the circuit, the pin being biased by a spring, making it possible, in the absence of any pressing form of the control button, to place the clamp in a fully closed position in which the clamp fully closes the circuit.
