Abstract
An instrument access device of a teleoperated surgical system includes an envelope, a clamp, and a plurality of ports. The envelope includes a distal opening and a cavity. The clamp is in the distal opening of the envelope. The plurality of ports are coupled to the envelope. The plurality of ports are proximal to the clamp and the distal opening of the envelope. Each of the plurality of ports includes a seal, which is sized and shaped to seal an outer surface of a cannula and to fix a position of the cannula relative to the port and the envelope.
Claims16
An instrument access device of a teleoperated surgical system, the instrument access device comprising:
- an envelope comprising a distal opening;
- a clamp in the distal opening of the envelope;
- and
- a plurality of ports coupled to the envelope, the plurality of ports being proximal to the clamp and the distal opening of the envelope, each of the plurality of ports including a seal, and each of the seals of the plurality of ports being sized and shaped to seal against an outer surface of a cannula extending through the envelope and to fix a position of the cannula relative to a port of the plurality of ports and the envelope,
- wherein on condition that the envelope is pressurized with insufflation gas the envelope extends radially outward beyond an outward periphery of the clamp.
An instrument access device of a teleoperated surgical system, the instrument access device comprising:
- an envelope comprising a distal opening;
- a clamp in the distal opening of the envelope;
- and
- a plurality of ports coupled to the envelope, the plurality of ports being proximal to the clamp and the distal opening of the envelope, each of the plurality of ports including a seal, and each of the seals of the plurality of ports being sized and shaped to seal against an outer surface of a cannula extending through the envelope and to fix a position of the cannula relative to a port of the plurality of ports and the envelope,
- wherein on condition that the envelope is pressurized with insufflation gas, the envelope comprises a substantially spherical shape.
An instrument access device comprising:
- means for enclosing a cavity into which a plurality of cannulas extend;
- a clamp for connecting the means for enclosing to a wound retractor;
- and
- means for sealing each of the plurality of cannulas,
- wherein each means for sealing is connected to the means for enclosing, and
- wherein each means for sealing is configured to fix a position of an individual one of the plurality of cannulas relative to the means for enclosing, and
- wherein on condition that the means for enclosing is pressurized with insufflation gas, the means for enclosing extends radially outward beyond an outward periphery of the clamp.
