The instrument drive connector includes a housing assembly, an elongate shaft extending distally from the housing assembly, and a first drive assembly disposed at least partially within the housing assembly and the elongate shaft. The first drive assembly includes a first drive screw, a first input drive coupler non-rotatably coupled to the proximal end of the first drive screw, and a screw body portion of the first drive screw. And a first drive nut that is movable in the longitudinal direction with respect to the first drive screw in response to rotation of the first drive screw, and a lock link. The locking link is coupled to the first drive nut and has an elongate body having a proximal end that is longitudinally movable relative to the first drive nut between a proximal unlocked position and a distal locked position. A distal end including a switch actuating assembly including a switch actuating arm biased toward a distal locking position. [Selection] Figure 1器具駆動コネクタは、ハウジング組立体と、ハウジング組立体から遠位に延びる細長いシャフトと、ハウジング組立体および細長いシャフト内に少なくとも部分的に配置された第１の駆動組立体とを含む。第１の駆動組立体は、第１の駆動ねじと、第１の駆動ねじの近位端に回転不能に連結された第１の入力駆動カプラと、第１の駆動ねじのねじ胴体部に螺合され第１の駆動ねじの回転に応じて第１の駆動ねじに対して長手方向に移動可能な第１の駆動ナットと、ロックリンクとを含む。ロックリンクは、第１の駆動ナットに連結され、近位非ロック位置と遠位ロック位置との間で第１の駆動ナットに対して長手方向に移動可能な近位端部を有する細長い本体と、遠位ロック位置に向かって付勢されたスイッチ作動アームを含むスイッチ作動組立体を含む遠位端部とを含む。 【選択図】図１
