Abstract: The invention provides a medical endoscope including a control handle (2) provided with a control mechanism and that, by means of an attachment system, is temporarily attached to a consumable medical instrument (3) 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; 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; in accordance with the invention, the control handle (2) and the consumable medical instrument (3) 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 controlled manner.

Abstract: An endoscope instrument includes an insertion tube of longitudinal axis possessing a proximal portion for connection to an actuation support and a distal portion presenting an outlet section occupied by a viewing zone and by at least one outlet orifice for passing at least one appliance for occupying a retracted position inside the tube and a working position in which the appliance occupies at least a portion of the outlet section. The distal portion of the insertion tube includes at least one radially deformable wall over a portion of its length extending from the outlet section, enabling the outlet section of the distal portion of the tube to be increased on the appliance passing from its retracted position in which the appliance does not stress the deformable wall to its working position in which the deformable wall is stressed radially.

Abstract: The invention relates to an imaging system comprising: a medical instrument (3) that is separable from a connection support (4), the separable medical instrument including an insertion tube provided with a non-volatile memory (23); an imaging appliance (11) including a processor and image display unit connected to the viewing system; and a control unit (20) enabling the operation of the imaging appliance (11) to be controlled and connected to a system (21) for detecting connection between the medical instrument (3) and the connection support (4). According to the invention, the non-volatile memory (23) contains identity data of the associated medical instrument and utilization data concerning the imaging appliance sent by the control unit (20) on each connection, and the control unit (20) authorizes operation of the imaging appliance (11) only if the user is identified and has given authorization. The medical instrument can thus be reused under the entire responsibility of the user.

Abstract: The invention relates to a medical instrument for an endoscope, the instrument comprising a flexible outer insertion tube (5) having a tubular wall possessing a proximal portion (6) for connection to an actuator support (3) and a distal portion (7) presenting an outlet section (8) and connected to a folding mechanism. The instrument comprises: an outer insertion tube (5) includes closure systems (10, 11) for closing its proximal portion (6) and its distal portion (7) to define an internal chamber (13) communicating beside the distal portion with the outside of the tube via at least one orifice (15) formed through the distal portion of the tubular wall, and beside the proximal portion, with a substance transit source (19); and a series of flexible tubular ducts (21i) mounted independently of one another inside the insertion tube (5) passing through the chamber (13) and the closure systems (10, 11) in order to open out to the outside of the outlet section (8) of the distal portion (7) of the tube.
