ADJUSTABLE SURGICAL PORTAL
A surgical portal includes a compressible, e.g., foam or rubber, portal having one or more longitudinal ports for passage of a surgical object. The portal is adapted to transition between a first condition having a first length and a second condition having a second length different from the first length. The portal includes an outer wall configured to maintain a substantial sealing relationship with tissue upon insertion therein.
1 . A surgical portal, which comprises:
a compressible portal having at least two longitudinal ports for passage of a surgical object, the portal being adapted to transition between a first condition having a first length and a second condition having a second length different from the first length, wherein the portal includes an outer wall configured to maintain a substantial sealing relationship with tissue upon insertion therein.
2 . The surgical portal of claim 1 , wherein the outer wall and the at least one longitudinal port truncates or elongates in response to the transition between the first condition and the second condition.
3 . The surgical portal of claim 1 , wherein the portal includes an insufflation passage disposed in mechanical cooperation with an insufflation conduit for the reception and passage of insufflation fluids.
4 . The surgical portal of claim 1 , wherein the portal includes three or more longitudinal ports.
5 . The surgical portal of claim 1 , wherein the portal is hour-glass shaped.
6 . A surgical portal, which comprises:
a compressible portal having at least two longitudinal ports for passage of a surgical object, the portal being adapted to be selectively positionable between a first condition having a first length and a second condition having a second length longer than the first length, wherein the portal includes an outer wall configured to maintain a substantial sealing relationship with tissue upon insertion therein, wherein the outer wall includes a plurality of segments, each segment being movable with respect to the other segments upon the selective positioning between the first condition and the second condition.
7 . The surgical portal of claim 6 , wherein each segment is configured for uniform movement with respect to the other segments.
8 . The surgical portal of claim 6 , wherein each segment expands outwardly in response to truncation of the portal and contracts inwardly in response to elongation of the portal.
9 . A surgical portal, which comprises:
a compressible portal having at least two longitudinal ports for passage of a surgical object and including a proximal member and a distal member, the portal being adapted to transition between a first condition having a first length and a second condition having a second length different from the first length, wherein the distal member is configured to at least partially enclose an outer surface of the proximal member when the portal is disposed in the first condition.
10 . The surgical portal of claim 9 , wherein the proximal and distal members are configured to slidably engage.
11 . The surgical portal of claim 9 , wherein the distal member defines an extension bore and the proximal member includes an extension portion such that the extension portion is configured to engage the extension bore.
12 . The surgical portal of claim 11 , wherein the extension portion and the extension bore are slidably engaged.
13 . The surgical portal of claim 11 , wherein the extension portion is configured for a substantial sealing relationship with the extension bore and tissue.
14 . The surgical portal of claim 11 , wherein at least a portion of the extension portion is offset from the distal member when the portal is disposed in the second condition.
