Abstract
A sterile barrier assembly includes a linear drive section and a rotation drive section. The linear drive section includes a corrugated portion interfacing with an axial output of an instrument driving unit on a non-sterile side and an engaging portion interfacing with a tool assembly of a surgical instrument on a sterile side. The rotational drive section includes a first engaging portion interfacing with a rotational output of the instrument driving unit on the non-sterile side and a second engaging portion interfacing with the tool assembly of the surgical instrument on the sterile side.

A sterile barrier assembly comprising:
- a linear drive section including:
- a corrugated portion interfacing with an axial output of an instrument driving unit on a non-sterile side;
- and
- an engaging portion interfacing with a tool assembly of a surgical instrument on a sterile side;
- and
- a rotational drive section including:
- a first engaging portion interfacing with a rotational output of the instrument driving unit on the non-sterile side;
- and
- a second engaging portion interfacing with the tool assembly of the surgical instrument on the sterile side.
A robotic surgical system comprising:
- a sterile instrument having a surgical tool manipulatable by a plurality of tool drivers in a plurality of directions;
- a non-sterile drive unit including a plurality of driven outputs;
- and
- a sterile barrier assembly partitioned into a sterile side coupled to the sterile instrument and a non-sterile side coupled to the non-sterile drive unit, the sterile barrier assembly including:
