Abstract
A surgical port includes an end face comprising a channel extending through the end face, the channel having a cross section shaped to receive a surgical instrument cannula, and a lateral wall extending around a perimeter of the end face, the lateral wall and end face enclosing an open volume. An end portion of a wound retractor is received in the open volume of the surgical port and in engagement with an inner surface of the lateral wall, and the surgical port is configured to abut a body wall in an inserted position of the wound retractor through the body wall.
Claims22
A system, comprising:
- a surgical port made of a deformable material, the surgical port comprising:
- an end face,
- a channel extending through the end face, the channel having a cross section shaped to receive a surgical instrument cannula,
- a lateral wall extending around a perimeter of the end face and terminating in a rim, the lateral wall and end face enclosing an open volume, and
- an apron portion extending radially outward from the lateral wall;
- and
- a wound retractor configured to be inserted through a body wall,
- wherein, in an inserted position of the wound retractor through the body wall, the rim of lateral wall of the surgical port is configured to stretch to fit around and engage a portion of the wound retractor to couple the surgical port with the wound retractor, and
- wherein in a coupled state of the surgical port with the wound retractor, the apron portion is configured to abut the body wall, and the channel of the surgical port is configured to position a remote center of a surgical instrument cannula received by the channel at a location of or exterior to the body wall.
A surgical port, comprising:
- an end face;
- a channel extending through the end face, the channel sized to receive and position a surgical instrument cannula through the surgical port;
- a lateral wall extending around a perimeter of the end face and terminating in a rim, the lateral wall and end face enclosing an open volume;
- and
- an apron portion extending radially outward from the lateral wall,
- wherein the port is made of a deformable material and the rim of the lateral wall is configured to stretch to fit around and engage with a portion of a wound retractor in an inserted position of the wound retractor through a body wall to couple the surgical port with the wound retractor, and
- wherein, in a coupled state of the surgical port with the wound retractor, the apron portion is configured to abut the body wall, and the channel is configured to position a remote center of motion of a surgical instrument cannula received by the channel at a location of or exterior to the body wall.
A method comprising:
- positioning a wound retractor through a body wall;
- coupling a surgical port with the wound retractor such that the surgical port abuts the body wall;
- and
- inserting a surgical instrument cannula though a channel in the surgical port, the channel being configured to position a remote center of motion of the surgical instrument cannula at or exterior to the body wall,
- wherein the surgical port is made of a deformable material, and
- wherein coupling the surgical port with the wound retractor comprises stretching a rim of the surgical port to fit around and engage with a portion of the wound retractor.
