MOTORISED AND MODULAR INSTRUMENTATION DEVICE AND ENDOSCOPY SYSTEM COMPRISING SUCH A DEVICE

摘要

A motorized, modular instrumentation device and an endoscopy system including such device. The motorized, modular instrumentation device includes at least one operational unit mounted on at least one support structure and integrating a motorized medical instrument module including, first, an elongated medical instrument with a tool arranged on one distal end, it being possible to bend the corresponding end portion of the instrument, and second, at least one electrical actuating element controlling the operation of the tool and/or the bending of the distal end portion, via transmission elements extending within the elongated body of the instrument. The actuating element(s) is/are installed in a hollow body connected to the proximal end of the instrument and the hollow body is itself arranged, with rotational guiding, within a reception housing adapted to move, at least translationally, on the support structure, the movements of the hollow body and the reception housing being motorized.

1. Motorized and modular instrumentation device for an endoscope or the like, in particular a flexible endoscope, comprising at least one operational unit mounted on at least one support structure, preferably an articulated support structure, with the unit or each unit integrating a motorized medical instrument module comprising, on the one hand, an elongated medical instrument with an actuator or a tool placed at a distal end, with the corresponding end portion of the instrument being able to undergo bending or arching in at least one plane and/or in at least one direction and, on the other hand, at least one motorized actuating means controlling the operating of the tool or the actuator and/or the bending or the arching of the distal end portion, where this is done by means of transmission means extending into the elongated body of the medical instrument, the latter also being able to be subjected to translational movements in the direction of its longitudinal axis and to rotational movements around this axis,
instrumentation device (1) characterized in that the actuating means (7, 7′) is (are) mounted in a hollow body (10) connected to the proximal end (5″) of the medical instrument (5) and in that said hollow body (10) is itself placed, with guiding in rotation around a suitable median axis (AM) extending the longitudinal axis (AL) of the medical instrument (5), in a receiving housing (11), where the latter is mounted with the ability to move at least in translation in the direction of the median axis (AM) of the hollow body (10), on the support structure (3), with the movements of the hollow body (10) and of the receiving housing (11) being motorized.
