Robotic surgical assemblies and adapter assemblies thereof

An adapter assembly for connecting an endoscope to a robotic surgical system, the adapter assembly comprising:

• a housing configured to be coupled to an instrument drive unit of a robotic surgical system, the housing having a main body configured to house a proximal end of an endoscope;
• a door pivotably coupled to the housing and movable between an open position and a closed position;
• and
• a locking assembly disposed within the housing and configured to releasably lock the door to the housing to lock a portion of the endoscope in the adapter assembly, wherein the locking assembly includes:
• a rotatable button disposed within the main body of the housing, the rotatable button having a finger,
• wherein the door includes an inwardly-extending projection configured to selectively interlock with the finger of the rotatable button when the door is in the closed position, the projection having a ramped end configured to engage the finger of the rotatable button to rotate the rotatable button when the door is moving towards the closed position.

An adapter assembly for connecting an endoscope to a robotic surgical system, the adapter assembly comprising:

• a proximal housing configured to be coupled to an instrument drive unit of a robotic surgical system, the proximal housing having a main body configured to house a proximal end of an endoscope;
• a distal housing extending distally from the proximal housing, the distal housing defining a hollow interior for non-rotatably retaining a portion of the endoscope therein;
• a door pivotably coupled to the proximal housing and movable between an open position and a closed position;
• and
• a locking assembly disposed within the proximal housing and configured to releasably lock the door to the proximal housing to lock the proximal end of endoscope in the adapter assembly, wherein the door is pivotably coupled to the main body of the proximal housing, and wherein the locking assembly includes:
• a rotatable button rotatably disposed within the main body of the proximal housing so as not to project therefrom, the rotatable button having a finger;
• and
• a biasing member resiliently biasing the finger of the rotatable button in a distal direction,
• wherein the door has an inwardly-extending projection configured to selectively interlock with the finger of the rotatable member when the door is in the closed position, the projection having a ramped end configured to engage the finger of the rotatable button to rotate the rotatable button against the resilient bias of the biasing member as the door is moving towards the closed position,
• wherein the projection of the door defines a cutout therein configured to receive at least a portion of the finger of the rotatable button to prevent the door from moving to the open position.
