Surgical robotic assemblies and instrument adapters thereof
First Claim
1. An instrument adapter for interconnecting a drive mechanism and an end effector, wherein the instrument adapter transmits driving forces from the drive mechanisms to the end effector for actuating the end effector, the instrument adapter comprising:
- a housing;
a drive member disposed within the housing;
a nut threadedly coupled to the drive member and axially movable relative thereto; and
a shaft assembly including;
a shaft having a proximal end coupled to the housing and a distal end configured to be operably coupled to the end effector; and
a link having a proximal end movably coupled to the nut and a distal end configured to selectively lock the end effector to the shaft assembly, the link being movable between a proximal non-locking position, and a distal locking position, wherein the nut is movable between a first position along the drive member, in which the nut resists proximal movement of the link from the distal position to the proximal position, and a second position along the drive member, in which the nut does not resist proximal movement of the link from the distal position to the proximal position.

Abstract
An instrument adapter includes a housing, a drive member, a nut, and a shaft assembly. The nut is threadedly coupled to the drive member and axially movable relative thereto. The shaft assembly includes a shaft and a link. The shaft extends distally from the housing and is configured to be operably coupled to an end effector. The link has a proximal end movably coupled to the nut and a distal end configured to selectively lock the end effector to the shaft assembly. The link is movable between a proximal non-locking position, and a distal locking position. The nut is movable between a first position along the drive member, in which the nut resists proximal movement of the link from the distal position to the proximal position, and a second position, in which the nut does not resist proximal movement of the link from the distal position to the proximal position.
