Hand access laparoscopic device
First Claim
1. A surgical access device adapted for disposition outside a body wall, the access device facilitating insertion of an instrument therethrough and maintenance of a sealing relationship with the instrument, comprising:
- a cap ring defining a central opening;
a gel pad coupled to the cap ring and sealing the central opening in the cap ring and forming an instrument seal in the presence of an instrument inserted therethrough and a zero seal in the absence of an instrument inserted therethrough, the gel pad including at least two regions of differing resiliency including a first region having a first resiliency and a second region having less resiliency than the first region;
a first fabric coupled to the cap ring; and
a second fabric coupled to the cap ring a distance from the first fabric, the space between the first fabric and the second fabric defining a cavity,wherein the gel pad is positioned within the cavity between the first and second fabric.

Abstract
The invention relates to a hand access laparoscopy device having a gelcap, a retainer, a sleeve and a retention ring. The gelcap includes gel that is bonded to a cap. The cap includes an inner cylindrical wall to which the gel in bonded, thereby providing a sealing area between the device and the wound in a body wall. By securing the gel to the inner cylindrical wall, the thickness of the gel and corresponding cap is minimized along with the overall footprint of the device. With the gel thickness reduced and able to be substantially flush, the “doming” phenomenon produced by insufflation of a patient'"'"'s abdomen is reduced.

11. A surgical access device adapted for disposition outside a body wall, the access device facilitating insertion of an instrument therethrough and maintenance of a sealing relationship with the instrument, comprising:
-
a cap ring defining a central opening; a gel pad coupled to the cap ring and sealing the central opening in the cap ring and forming an instrument seal in the presence of an instrument inserted therethrough and a zero seal in the absence of an instrument inserted therethrough, the gel pad including at least two regions of differing resiliency including a first region having a first resiliency and a second region having less resiliency than the first region; wherein the cap ring includes at least one gap along the cap ring, the at least one gap creating at least one first end and at least one second end of the cap ring in which the gel pad couples to the at least one first end of the cap ring to the at least one second end of the cap ring and the cap ring further comprises a buckle fitting arranged to couple the at least one first end of the cap ring to the at least one second end of the cap ring closing the at least one gap. - View Dependent Claims (12, 13)

14. A surgical access device adapted for disposition outside a body wall, the access device facilitating insertion of an instrument therethrough and maintenance of a sealing relationship with the instrument, comprising:
-
a cap ring defining a central opening; a gel pad coupled to the cap ring and sealing the central opening in the cap ring and forming an instrument seal in the presence of an instrument inserted therethrough and a zero seal in the absence of an instrument inserted therethrough, the gel pad including at least two regions of differing resiliency including a first region having a first resiliency and a second region having less resiliency than the first region; wherein the cap ring has a first state defining a first annular perimeter and a second state defining a second annular perimeter smaller than the first annular perimeter of the cap ring, the gel pad being relaxed in the first state and compressed by the cap ring in the second state.
