Abstract
In accordance with at least one aspect of this disclosure, an access port for performing an endoscopic surgical procedure in a surgical cavity of a patient includes a proximal housing portion. The proximal housing portion includes, a central lumen providing instrument access to the surgical cavity and an engagement housing operatively associated with a proximal end of the proximal housing portion and having a circumferential engagement area formed therein that is adapted and configured to releasably accept a grasping member of a surgical robot. An elongated tubular body portion extends from the proximal housing portion in communication with the central lumen.
Claims7
An access port for performing an endoscopic surgical procedure in a surgical cavity of a patient, comprising:
- a proximal housing portion including a central lumen providing instrument access to the surgical cavity, wherein the proximal housing portion defines an interior plenum;
- an engagement housing operatively associated with a proximal end of the proximal housing portion and having a concave circumferential engagement area formed therein that is adapted and configured to releasably accept a grasping member of a surgical robot, wherein the concave engagement area is defined between an upper annular engagement housing portion and a lower annular engagement housing portion, and wherein the upper annular engagement housing portion and the lower annular engagement housing portion are of equal outer diameter;
- a seal housed within the interior plenum, wherein the engagement housing is proximal relative to the interior plenum and to the seal;
- and
- an elongated tubular body portion extending from the proximal housing portion in a distal direction, in communication with the central lumen.
A gas sealed access port for performing an endoscopic surgical procedure in a surgical cavity of a patient, comprising:
- a proximal housing portion including a central lumen providing gas sealed access to the surgical cavity, an inlet path for communicating with a source of pressurized gas, a tapered neck portion, an interior cavity accommodating a seal including an annular jet assembly for receiving pressurized gas from the inlet path to generate a gaseous seal within the tapered neck portion to maintain a stable pressure within the surgical cavity;
- an engagement housing operatively associated with a proximal end of the proximal housing portion and having a concave circumferential engagement area formed therein that is adapted and configured to releasably accept a grasping member of a surgical robot, wherein the concave circumferential engagement area is defined between an upper annular engagement housing portion and a lower annular engagement housing portion, and wherein the upper annular engagement housing portion and the lower annular engagement housing portion are of equal outer diameter;
- and
- an elongated tubular body extending distally from the tapered neck portion of the proximal housing in communication with the central lumen.
