Sterile interface module for robotic surgical assemblies

A robotic surgical system, comprising:

• a surgical instrument including an end effector;
• a robotic surgical assembly;
• and
• a sterile interface module supported between the robotic surgical assembly and the surgical instrument to couple the surgical instrument to the robotic surgical assembly, the sterile interface module including:
• a body member configured to selectively couple the surgical instrument to the robotic surgical assembly;
• a decoupling collar supported on the body member and movable relative to the body member from a first position to a second position;
• a support plate coupled to the decoupling collar, the support plate having an initial un-used condition and a locked used condition;
• a plurality of locking tabs extending from the body member and selectively engageable with the support plate to prevent the decoupling collar from moving from the second position to the first position, the plurality of locking tabs extending away from one another and each locking tab of the plurality of locking tabs terminating in a free end, wherein:
• when the support plate is in the initial un-used condition the support plate is not engaged by the plurality of locking tabs, and
• when the support plate is in the locked used condition the support plate is engaged by the free end of each locking tab of the plurality of locking tabs to prevent return of the support plate to the initial un-used condition;
• and
• a reset cam translatably supported about the plurality of locking tabs, wherein as the reset cam translates along the locking tabs, towards the free ends of the locking tabs, the support plate is free to move from the locked used condition to the initial un-used condition.
