Abstract

An instrument drive connector includes a housing assembly, an elongated shaft extending distally from the housing assembly, and a first drive assembly at least partially disposed within the housing assembly and the elongated shaft. The first drive assembly includes a first drive screw, a first input drive coupler non-rotatably coupled to a proximal end of the first drive screw, a first drive nut threadedly engaged with a threaded body portion of the first drive screw and longitudinally movable relative thereto in response to rotation of the first drive screw, and a locking link. The locking link includes an elongated body having a proximal end portion coupled to the first drive nut and longitudinally movable relative thereto between a proximal non-locking position and a distal locking position, and a distal end portion including a switch actuation assembly including a switch actuating arm biased towards the distal locking position.

Dependent claims

A surgical assembly, comprising:

an instrument drive unit;
a surgical loading unit including an end effector;
and
an instrument drive connector interconnecting the instrument drive unit and the surgical loading unit, the instrument drive connector including a housing assembly and an elongated shaft extending distally from the housing assembly, the housing assembly releasably coupled to the instrument drive unit and the elongated shaft releasably coupled to the surgical loading unit, the instrument drive connector supporting a locking assembly including:
a first drive screw operably coupled to the instrument drive unit;
a first drive nut coupled to the first drive screw and longitudinally movable relative thereto in response to rotation of the first drive screw;
and
a first drive member coupled to the first drive nut and longitudinally movable relative thereto between a non-locking position in which the first drive member does not prevent attaching or detaching of the surgical loading unit to the instrument drive connector and a locking position in which the first drive member prevents attaching or detaching of the surgical loading unit to the instrument drive connector,
the instrument drive connector having:
a load state in which the first drive member is movable between the non-locking and locking positions such that the surgical loading unit can be inserted onto the instrument drive connector;
an unload state in which the first drive member is in the non-locking position such that the surgical loading unit can be removed from the instrument drive connector;
and
a locked state in which the first drive member is in the locking position such that the surgical loading unit cannot be inserted onto or removed from the instrument drive connector.

the instrument drive connector having:
a load state in which the first drive member is in the non-locking position such that the surgical loading unit can be inserted onto the instrument drive connector;
an unload state in which the first drive member is in the non-locking position such that the surgical loading unit can be removed from the instrument drive connector;
and
a locked state in which the first drive member is in the locking position such that the surgical loading unit cannot be inserted onto or removed from the instrument drive connector.
