Instrument Access Device
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.
1 . An instrument access device comprising:
a proximal member for location externally of an opening into a body cavity;
a first instrument receiver for receiving an instrument;
a first connector extending between the proximal member and the first instrument receiver;
a second instrument receiver for receiving an instrument; and
a second connector extending between the proximal member and the second instrument receiver.
2 . A device as claimed in claim 1 wherein at least one of the connectors is substantially rigid.
3 . A device as claimed in claim 1 comprising a joint between at least one of the connectors and the proximal member which facilitates movement of the connector relative to the proximal member.
4 . (canceled)
5 . (canceled)
6 . A device as claimed in claim 1 comprising a formation between the connector and the proximal member to facilitate relative movement between the connector and the proximal member.
7 . (canceled)
8 . A device as claimed in claim 1 comprising a spacer for location between the proximal member and the outside of a wound opening.
9 - 12 . (canceled)
13 . A device as claimed in claim 1 wherein at least one of the connectors comprises an instrument seal.
14 . A device as claimed in claim 1 comprising a flexible cannula extending from at least one of the connectors.
15 - 17 . (canceled)
18 . A device as claimed in claim 1 comprising a third instrument receiver for receiving an instrument and a third connector extending between the proximal member and the first instrument receiver.
19 . A device as claimed in claim 1 comprising an opening in the proximal member which is sized to receive a small instrument or a tube.
20 - 23 . (canceled)
24 . A device as claimed in claim 1 wherein at least one of the connectors has an associated seal or valve.
25 . A device as claimed in claim 24 wherein the seal comprises a first valve and a second valve distal of the first valve.
26 - 36 . (canceled)
37 . A device as claimed in claim 1 comprising a distal anchoring member for location within a wound interior; and a retractor member extending proximally from the distal anchoring member to retract laterally the sides of a wound opening.
38 . A device as claimed in claim 37 wherein the retractor member extends at least between the distal anchoring member and the proximal member.
39 - 43 . (canceled)
44 . A device as claimed in claim 1 wherein the proximal member comprises an inner part and an outer part.
45 . A device as claimed in claim 44 wherein the retractor member extends between the inner part and the outer part.
46 . A device as claimed in claim 1 comprising a mounting member for mounting to the proximal member.
47 . A device as claimed in claim 46 wherein the mounting member is releasably mounted to the proximal member.
48 . (canceled)
49 . (canceled)
50 . A device as claimed in claim 46 wherein the device comprises a clamp to clamp the mounting member to the proximal member.
51 . An instrument access device comprising:
a proximal member for location externally of an opening into a body cavity;
a first instrument receiver for receiving an instrument;
a second instrument receiver for receiving an instrument;
a proximal mounting for locating outside of a wound opening;
the proximal member being releasably mounted to the proximal mounting; and
a flexible spacer for location between the proximal mounting and the outside of a wound opening.
