Aspects of the invention relate to systems, devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display.

This application discloses a medical device for surgical procedures, particularly relating to procedures for manipulating the end effector of a surgical instrument near the skin surface at an incision site. According to some embodiments, an instrument access device is configured to be coupled to a wound retractor at a distal end of the device and to receive multiple instrument entry guides in a port at a proximal end of the instrument access device, wherein a sash is located between a distal and proximal end defining a sealed cavity for maintaining inflated pressure. Various embodiments provide means for rotating an auxiliary port in the sash about the port receiving the instrument entry guide without twisting the sash. Various sash shapes are also disclosed. An instrument entry guide aligned with the axis of a surgical instrument is also disclosed.

Medical devices for surgical procedures are disclosed, particularly procedures involving manipulation of a surgical instrument end effector proximate a skin surface at an incision site. According to some embodiments, an instrument access device is configured to couple to a wound retractor at a distal end of the device and receive a multi-instrument entry guide in a port at a proximal end of the instrument access device, with an envelope between a distal end and a proximal end defining a sealed cavity for maintaining a gas pressure. Various embodiments provide means for rotating an auxiliary port in the envelope around a port receiving an instrument entry guide without twisting the envelope. Various envelope shapes are also disclosed. An instrument entry guide that aligns a surgical instrument shaft is also disclosed.
