Claim:
A medical appliance comprising a medical instrument ( 2 ) separable from an actuator support ( 3 ), the appliance including a connection and disconnection system ( 4 ) between the instrument ( 2 ) and the support ( 3 ), and being characterized in that the connection and disconnection system comprises: a connector ( 6 ) carried by the instrument and including a guide ( 9 ) for actuator rods ( 11 ) held resiliently by return springs ( 17 ) in the guide by heads ( 12 ) projecting from the free end of the guide, the connector ( 6 ) being provided with a rotary coupling member ( 20 ) and having a transverse end face ( 9 1 ) on which the heads ( 12 ) are held pressed against the transverse end face ( 9 1 ) by the return springs ( 17 ); and a connection endpiece ( 7 ) of longitudinal axis (Y) carried by the support and including a cam engagement ( 29 ) in the form of a disk guided in rotation in a plane perpendicular to the longitudinal axis (Y), reception setbacks ( 30 ) being arranged in the cam engagement ( 29 ) and distributed in an angular disposition that is identical to that of the head ( 12 ) of the actuator rods ( 11 ) that are to penetrate together into the insides of the setbacks ( 30 ), the cam engagement ( 29 ) being fitted with a rotary coupling member ( 33 ) complementary to the rotary coupling member ( 20 ) presented by the connector ( 6 ), the endpiece ( 7 ) also presenting hooks ( 36 ) connected to an actuator system ( 37 ), each hook ( 36 ) including a housing ( 38 ) for receiving the head ( 12 ) of the actuator rod ( 11 ), the hooks ( 36 ) being arranged in such a manner that the housings ( 38 ) are in alignment in a common plane extending transversely to the longitudinal axis (Y), the cam engagement ( 29 ) being engaged in at least some of the housings ( 38 ), while the setbacks ( 30 ) of the cam extend outside the hooks ( 36 ) to receive the heads ( 12 ) of the actuator rods ( 11 ), the endpiece ( 7 ) and the connector ( 6 ) occupying a connection position after they have approached each other axially, leading firstly to rotary coupling between the connector ( 6 ) and the engagement cam ( 29 ) and secondly to disengagement of the head ( 12 ) of the rod from the transverse end face ( 9 1 ) of the guide ( 9 ) so that said head ( 12 ) is engaged inside the reception setback ( 30 ) presented by the engagement cam, axial approach being followed by a movement in rotation between the connector ( 6 ) and the connection endpiece ( 7 ) to turn the engagement cam ( 29 ) relative to the actuator hooks ( 36 ) so as to move the head ( 12 ) of the rod until it co-operates with the hook ( 36 ) in order to provide a mechanical connection between the head ( 12 ) of the rod and the actuator hook ( 36 ).
