## 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.

## Claims

### 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 bonded 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.

### Claim 2 (depends on 1)

The surgical access device of claim 1, wherein:
the retainer including at least one resilient snap for releasably coupling the retainer to the cap, the at least one snap extending from the outer periphery of the retainer in a substantially perpendicular direction from a substantially planar, annular surface of the retainer;
each of the at least one snaps having a projection extending substantially perpendicular and radially inwardly from the snap;
the at least one snap being configured to deflect radially outwardly to slide over a corresponding lip portion of the cap when the cap and retainer are brought together in a mating relationship; and
the at least one snap being configured to return toward a neutral position after the projection on the at least one snap passes the lip portion of the cap such that the projection of the at least one snap engages a receiver portion of the cap.

### Claim 3 (depends on 2)

The surgical access device of claim 2, the planar, annular surface of the retainer being configured to secure the sleeve to the retainer.

### Claim 4 (depends on 2)

The surgical access device of claim 2, wherein:
the retainer including a sidewall portion adjacent to each of the at least one snaps and on either side of each of the at least one snaps; and
the cap including openings disposed along the edges of the cap for receiving the sidewall portions of the retainer.

### Claim 5 (depends on 1)

The surgical access device of claim 1, the cap including an inner cylindrical wall and the gel pad being bonded to the inner cylindrical wall.

### Claim 6 (depends on 5)

The surgical access device of claim 5, the gel pad being molded to the cap.

### Claim 7

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 bonded 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, the retainer including at least one resilient snap for releasably coupling the retainer to the cap, the at least one snap extending from the outer periphery of the retainer in a substantially perpendicular direction from a substantially planar, annular surface of the retainer, each of the at least one snaps having a projection extending substantially perpendicular and radially inwardly from the snap, the retainer including a sidewall portion adjacent to each of the at least one snaps and on either side of each of the at least one snaps,
wherein the cap including openings disposed along the edges of the cap for receiving the sidewall portions of the retainer,
the at least one snap being configured to deflect radially outwardly to slide over a corresponding lip portion of the cap when the cap and retainer are brought together in a mating relationship,
the at least one snap being configured to return toward a neutral position after the projection on the at least one snap passes the lip portion of the cap such that the projection of the at least one snap engages a receiver portion of the cap,
the retainer being configured to be coupled to a proximal portion of an elongate sleeve that is adapted to extend through the incision,
the planar, annular surface of the retainer being configured to secure the sleeve to the retainer, and
the retainer being adapted together with the elongate sleeve to retract the incision.

### Claim 8

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 inner cylindrical wall, the inner cylindrical wall defining an opening through the cap;
a gel pad bonded to the inner cylindrical wall of 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.

### Claim 9 (depends on 8)

The surgical access device of claim 8, the gel pad being molded to the cap.

### Claim 10 (depends on 8)

The surgical access device of claim 8, wherein the bonding of the gel pad to the inner cylindrical wall of the cap comprises at least one of mechanical bonding, adhesive bonding, and solvent bonding.

### Claim 11 (depends on 8)

The surgical access device of claim 8, wherein the bonding of the gel pad to the inner cylindrical wall of the cap comprises portions of the gel pad extending through apertures disposed on the inner cylindrical wall of the cap, thereby mechanically bonding the gel pad to the cap.
