Abstract

An instrument access device comprises first, second and third instrument seals for sealing around instruments extended through the device. The seals have respective connector sleeves. Each sleeve connects a base to one of the instrument seals. The device also comprises two insufflation/desufflation ports. Each of the ports comprises a connector extending from the base, a tube extending from the connector, a luer connector and a removable cap. The luer connector is used for connection to any suitable supply line for insufflation gas or for discharge if insufflation gas. In use, the insufflation/desufflation ports facilitate independent control of insufflation and desufflation as may be required during a surgical procedure. Access sleeve at the proximal end is cut-off, folded over the inner proximal ring and is held in place between the base and the inner proximal ring when the base is fitted. The proximal end of the sleeve that is generated when the sleeve is pulled upwardly to retract an incision is removed from the field of use.

Claims

1. An instrument access device, comprising:

a first instrument seal to effect a seal around a first instrument extended through the device, and

a second instrument seal to effect a seal around a second instrument extended through the device, the instrument seals being configured to be arranged in sealing relationship to a body of a patient;

a distal anchoring member for location within a wound interior;

a proximal member for location externally of a wound opening;

a retractor member extending proximally from the distal anchoring member to retract laterally the sides of the wound opening, wherein the retractor member includes a proximal portion for location externally of the wound opening, and retraction is adjusted by shortening an axial extent of the retractor member between the proximal member and the distal anchoring member by moving the proximal portion of the retractor member; and

a connector member to connect the proximal member to the instrument seals, the proximal member being configured for assisting in retaining a proximal end of the retractor member,

wherein the outer radial dimension of the connector member is less than that of the proximal member.

2. A device as claimed in claim 1 wherein the connector member is engagable with the proximal member.

3. A device as claimed in claim 1 wherein the connector member is releasably mounted to the proximal member.

4. A device as claimed in claim 1 wherein the connector member is mounted to the proximal member in an interference fit arrangement.

5. A device as claimed in claim 1 wherein the connector member is mounted to the proximal member in a snap-fit arrangement.

6. A device as claimed in claim 5 wherein the connector member comprises at least one protrusion for engagement with the proximal member.

7. A device as claimed in claim 1 wherein the retractor member extends at least between the distal anchoring member and the proximal member.

8. An instrument access device, comprising:

a first instrument seal to effect a seal around a first instrument extended through the device;

a second instrument seal to effect a seal around a second instrument extended through the device, the instrument seals being configured to be arranged in sealing relationship to a body of a patient;

a distal anchoring member for location within a wound interior;

a retractor member extending proximally from the distal anchoring member to retract laterally the sides of a wound opening;

a proximal member for location externally of a wound opening, the proximal member being configured for assisting in retaining a proximal end of the retractor member; and

a connector member to connect the proximal member to the instrument seals, wherein the outer radial dimension of the connector member is less than that of the proximal member,

wherein the connector member comprises an outer collar for engagement with the proximal member, and

wherein the first instrumental seal is laterally movable with respect to the proximal member, the second instrumental seal is laterally movable with respect to the proximal member, the first and second instrument seals are angled distally toward a central axis of the device, and the first and second instrument seals are movable with respect to each other.

9. An instrument access device, comprising:

a first instrument seal to effect a seal around a first instrument extended through the device;

a second instrument seal to effect a seal around a second instrument extended through the device, the instrument seals being configured to be arranged in sealing relationship to a body of a patient;

a distal anchoring member for location within a wound interior;

a retractor member extending proximally from the distal anchoring member to retract laterally the sides of a wound opening;

a proximal member for location externally of a wound opening, the proximal member being configured for assisting in retaining a proximal end of the retractor member; and

a connector member to connect the proximal member to the instrument seals, wherein the outer radial dimension of the connector member is less than that of the proximal member, and

wherein the retractor member extends in two layers between the distal anchoring member and the proximal member, wherein the two layers include a radially inner layer and a radially outer layer, and the retraction is adjusted by shortening an axial extent of the retractor member between the proximal member and the distal anchoring member.

10. An instrument access device, comprising:

a first instrument seal to effect a seal around a first instrument extended through the device, and

a second instrument seal to effect a seal around a second instrument extended through the device, the instrument seals being configured to be arranged in sealing relationship to a body of a patient;

a distal anchoring member for location within a wound interior;

a proximal member for location externally of a wound opening;

a retractor member extending proximally from the distal anchoring member to retract laterally the sides of the wound opening, wherein the retraction is adjusted by shortening an axial extent of the retractor member between the proximal member and the distal anchoring member;

a connector member to connect the proximal member to the instrument seals, the proximal member being configured for assisting in retaining a proximal end of the retractor member, wherein the proximal member is separate from and movable with respect to the retractor member, and

wherein the outer radial dimension of the connector member is less than that of the proximal member.
