Hand access laparoscopic device
First Claim
1. A surgical access device adapted for disposition relative to an incision in a body wall, the access device facilitating insertion of an instrument therethrough and maintenance of a sealing relationship with the instrument, comprising:
- a cap, the cap being substantially annular and having an opening therethrough;
a gel pad coupled to the cap and adapted for insertion of the instrument therethrough, the gel pad covering and sealing the entire opening in the cap;
a retainer, the retainer being substantially annular and adapted for placement against the body wall; and
coupling means adapted for coupling the cap and the retainer together,wherein the retainer being configured to be coupled to a proximal portion of an elongate sleeve that is adapted to extend through the incision, and the retainer being adapted together with the elongate sleeve to retract the incision;
wherein the gel pad has an outer surface, an inner surface and a plurality of regions having differing resiliency, each region of the plurality of regions having an top surface and each top surface of each region collectively forming the outer surface of the gel pad.

Abstract
The application 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.

7. A surgical access device adapted for disposition relative to a body wall, the access device facilitating insertion of an instrument therethrough and maintenance of a sealing relationship with the instrument, comprising:
-
a cap defining a central opening and arranged to connect to a retractor; and a gel pad connected to the cap and sealing the central opening in the cap 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; a retainer connectable to the cap and connected to a proximate portion of an elongate sleeve; and a retention ring attached to a distal portion of the elongate sleeve and a plurality of stabilizers extending from the retention ring and into the gel pad; wherein the gel pad has at least two concentric regions having differing resiliency. - View Dependent Claims (8, 9, 10, 11, 12)

13. A surgical access device adapted for disposition relative to a body wall, the access device facilitating insertion of an instrument therethrough and maintenance of a sealing relationship with the instrument, comprising:
-
a cap defining a central opening and arranged to connect to a retractor; a gel pad connected to the cap and sealing the central opening in the cap 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; a first fabric coupled to the cap; and a second fabric coupled to the cap, 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. - View Dependent Claims (14, 15, 16, 17, 18, 19)
