Abstract

An instrument access device 1 comprises a proximal member 25 for location externally of an opening into a body cavity. A first connector 20 extends between the proximal member 25 and a first instrument receiver 2. A second connector 21 extends between the proximal member and a second instrument receiver 3. Instrument seals can be housed in relatively rigid housings for added strength.

Claims

1. A medical device, comprising:

a wound protector, including;

a proximal ring assembly including a proximal ring member having a central longitudinal axis,

a distal ring,

a wound-engaging sleeve extending between the proximal ring member and the distal ring, and

the proximal ring assembly further including a sealing member having a plurality of access portions that provide access through the sealing member into the wound-engaging sleeve, wherein the plurality of access portions include;

a central access portion having a central longitudinal axis coaxial with the central longitudinal axis of the proximal ring member, and

a peripheral access portion having a central longitudinal axis offset from the central longitudinal axis of the central access portion, wherein a width of the peripheral access portion is less than a width of the central access portion,

wherein the central access portion includes a first tube extending proximal to a proximalmost end of the proximal ring member, the width of the central access portion being a width of the first tube at a first location proximal to the proximalmost end of the proximal ring member, and the peripheral access portion includes a second tube extending proximal to the proximalmost end of proximal ring member, the width of the peripheral access portion being a width of the second tube at a second location proximal to the proximalmost end of the proximal ring member.

2. The medical device of claim 1, wherein the sealing member further includes at least one seal for sealing at least one of the plurality of access portions.

3. The medical device of claim 1, wherein the peripheral access portion is one of a plurality of peripheral access portions having central longitudinal axes offset from the central longitudinal axis of the central access portion.

4. The medical device of claim 1, wherein the sealing member further comprises a reinforcing ring enveloped by a flexible material, where the reinforcing ring is more rigid than the flexible material.

5. The medical device of claim 1, wherein the sealing member further comprises a reinforcing ring enveloped by a flexible material, where the reinforcing ring is more rigid than the flexible material.

6. A medical device, comprising:

a wound protector, including;

a proximal ring assembly including a proximal ring member,

a distal ring,

a wound-engaging sleeve extending between the proximal ring member and the distal ring, and

the proximal ring assembly further including a sealing member having a central longitudinal axis and a plurality of access portions that provide access through the sealing member into the wound-engaging sleeve, wherein the plurality of access portions include;

a central access portion having a central longitudinal axis coaxial with the central longitudinal axis of the sealing member, and

a peripheral access portion having a central longitudinal axis offset from the central longitudinal axis of the central access portion, wherein a width of the peripheral access portion is less than a width of the central access portion,

wherein the width of the central access portion is at a position where the central access portion has a circular cross-section, and the width of the peripheral access portion is at a position where the peripheral access portion has a circular cross-section.

7. The medical device of claim 6, wherein the peripheral access portion is one of a plurality of peripheral access portions having central longitudinal axes offset from the central longitudinal axis of the central access portion.

8. The medical device of claim 6, wherein the central longitudinal axis of the sealing member is coaxial with a central longitudinal axis of the proximal ring member.

9. The medical device of claim 6, wherein the sealing member further includes at least one seal for sealing at least one of the plurality of access portions.

10. The medical device of claim 6, wherein at least one of the central and peripheral access portions includes a tubular member extending proximal to the proximal ring member, and the width of the at least one of the central and peripheral access portions is a width of the tubular member proximal to a proximalmost edge of the proximal ring member.

11. The medical device of claim 6, wherein the sealing member engages a proximalmost end of the proximal ring member.

12. A medical device, comprising:

a wound protector, including;

a proximal ring assembly including a proximal ring member having a central longitudinal axis,

a distal ring,

a wound-engaging sleeve extending between the proximal ring member and the distal ring, the wound-engaging sleeve, and

the proximal ring assembly further including a cover having a plurality of passageways that provide access through the cover into the wound-engaging sleeve, wherein the plurality of passageways include;

a first passageway having a central longitudinal axis coaxial with the central longitudinal axis of the proximal ring member, and

a second passageway having a central longitudinal axis offset from the central longitudinal axis of the central access portion, wherein a width of the second passageway is less than a width of the first passageway, and wherein the widths of the first and second passageways are measured at a position proximal to a proximalmost end of the wound protector,

wherein the width of the first passageway is a diameter of a circular portion of the first passageway, and the width of the second passageway is a diameter of a circular portion of the second passageway.

13. The medical device of claim 12, wherein one of the first passageway and the second passageway includes a tubular member extending proximal to the proximal ring member.

14. The medical device of claim 13, wherein the tubular member has a proximal end, and the cover further includes a valve at the proximal end for sealing the tubular member.

15. The medical device of claim 12, wherein the cover further includes at least one valve for sealing at least one of the plurality of passageways.

16. The medical device of claim 12, wherein the cover comprises a flexible material, and a reinforcing ring for stiffening the flexible material.

17. The medical device of claim 12, wherein the cover extends proximal to the proximal ring member.
