Abstract

An access port device is provided which enables hand access to a patient'"'"'s body cavity while retaining pneumoperitoneum by minimizing gas leakage through the access port device. In one embodiment, the access port device includes first and second sleeves forming an inflatable chamber and a third sleeve mounted within the second sleeve including an elastic band for sealingly engaging a hand or wrist. The access port device may also include an exit opening seal for positioning within the patient'"'"'s body cavity and a second sleeve retraction prevention device for preventing inadvertent movement of the second sleeve outwardly from the patient'"'"'s body cavity through the incision. In another embodiment, an access port device provided which includes an inner annular sealing device and a non-adhesive outer annular sealing device for creating a non-adhesive seal against the outer surface of a patient. An access component forming an inflatable chamber and including an integral sleeved glove may also be provided. In another embodiment, a sealing force applying feature includes a biasing surface formed on a generally flat annular extension and exposed to gas pressure in an adjacent gas chamber positioned to receive leakage gas leakage between the access port device an the patient to create sealing forces which tend to enhance the seal between the flexible annular extension and patient'"'"'s skin.

Claims

1. An access port device for use in surgery, comprising:

a first sleeve of flexible material including a proximal end and a distal end;

a securing device attached to said distal end of said first sleeve to secure the access port device externally to a patient;

a second sleeve of flexible material attached to the proximal end of said first sleeve, said second sleeve including an entry opening adjacent said proximal end of said first sleeve and an exit opening positioned a spaced distance from said entry opening;

an inflatable chamber formed between said first and said second sleeves;

a third sleeve of flexible material attached to at least one of said first sleeve and said second sleeve, said third sleeve including an annular elastic band positioned between said entry and said exit openings of said second sleeve to sealingly engage a surgeon'"'"'s arm extending through said third sleeve.

2. An access port device as claimed in claim 1, wherein said third sleeve is of a sufficient length to be positioned adjacent said exit opening.

3. An access port device as claimed in claim 2, wherein said third sleeve extends along a substantial portion of said second sleeve.

4. An access port device as claimed in claim 3, wherein said third sleeve is attached to said second sleeve at a first attachment location adjacent said entry opening and as a second attachment location a spaced distance along said second sleeve from said first attachment location.

5. An access port device as claimed in any preceding claim wherein said elastic band is positioned at a distal end of said third sleeve.

6. An access port device for use in surgery, comprising:

a first sleeve of flexible material including a proximal end and a distal end;

a securing device attached to said distal end of said first sleeve to secure the access port externally to a patient;

a second sleeve of flexible material attached to the proximal end of said first sleeve, said second sleeve including an entry opening adjacent said proximal end of said first sleeve and an exit opening positioned a spaced distance from said entry opening for insertion into an incision formed in a patient'"'"'s body;

an inflatable chamber formed between said first and said second sleeves;

an elongated exit opening seal mounted on said second sleeve at said exit opening, said exit opening seal positioned along an exit opening seal plane extending through said entry opening and said exit opening of said second sleeve;

a second sleeve retraction prevention means for preventing inadvertent retraction of said second sleeve from the incision, said second sleeve retraction prevention means including at least one transverse wing extending transverse to said exit opening seal plane.

7. An access port device as claimed in claim 6, wherein said at least one transverse wing includes at least one first wing positioned on a first side of said exit opening and at least one second wing positioned on a second side of said exit opening.

8. An access port device as claimed in claim 7, wherein each of said at least one first wing and said at least one second wing includes a pair of wings.

9. An access port device as claimed in any of claims 6 to 8, wherein said at least one transverse wing is integrally formed on said elongated exit opening seal.

10. An access port device as claimed in any of claims 6 to 8, wherein said elongated exit opening seal includes a pair of opposed bands biased together, said at least one transverse wing integrally formed on at least one band of said pair of opposed bands.

11. An access port device as claimed in claim 10, wherein said at least one transverse wing includes a first pair of wings and a second pair of wings.

12. An access port device as claimed in claim 11, wherein said first pair of wings is located at a first end of said pair of opposed bands and said second pair of wings is located at a second end of said pair of opposed bands.

13. An access port device as claimed in claim 12, wherein one wing of said first pair and one wing of said second pair of wings extend from one band of said pair of opposed bands in a first transverse direction and the other wing of said first pair and the other wing of said second pair of wings extend from the other band in a second transverse direction opposite said first transverse direction.
