Abstract

A surgical access device includes a housing member, a tubular member, a rotor and a lever. The housing member defines a lumen therethrough and includes a port in fluid communication with the lumen. The tubular member defines a longitudinal axis and a channel therethrough in fluid communication with the lumen of the housing member. The rotor defines a longitudinal passage therethrough and a bore on a sidewall of the rotor. The rotor is rotatably associated with the housing member and is coupled to the tubular member. The lever is translatably mounted on the housing member. Axial translation of the lever causes rotation of the rotor about the longitudinal axis between an open position in which the bore is aligned with the port providing a fluid communication between the port and the tubular member and a closed position in which the side wall of the rotor closes off the port.

Claims

1. A surgical access device comprising:

a housing member defining a lumen therethrough, the housing member including a port in fluid communication with the lumen;

a tubular member defining a channel therethrough in fluid communication with the lumen of the housing member, the tubular member defining a longitudinal axis;

a rotor defining a longitudinal passage therethrough and a bore on a sidewall of the rotor, the rotor rotatably associated with the housing member and coupled to the tubular member; and

a lever translatably mounted on the housing member, wherein axial translation of the lever causes rotation of the rotor about the longitudinal axis between an open position in which the bore is aligned with the port providing a fluid communication between the port and the tubular member and a closed position in which the sidewall of the rotor closes off the port, wherein the lumen of the housing member and the longitudinal passage of the rotor are in communication to receive a surgical instrument therethrough independent of a rotational position of the rotor.

2. The surgical access device according to claim 1, wherein the lever includes first and second members in a substantially superposed relation with each other.

3. The surgical access device according to claim 2, wherein the first member is slidably disposed on an outer surface of the housing member and the second member is slidably disposed on an inner surface of the housing member.

4. The surgical access device according to claim 3, wherein an inner surface of the second member of the lever defines a groove along a length thereof.

5. The surgical access device according to claim 4, wherein the rotor includes a nub radially extending from the sidewall of the rotor, the nub slidably engaging the groove defined in the second member.

6. The surgical access device according to claim 4, wherein the groove of the lever defines an acute angle with respect to the longitudinal axis of the tubular member.

7. The surgical access device according to claim 5, wherein the nub of the rotor is oriented at an angle with respect to the longitudinal axis of the tubular member.

8. The surgical access device according to claim 3, wherein the housing member includes a circumferential ridge radially extending from the inner surface thereof.

9. The surgical access device according to claim 8, wherein the rotor defines a circumferential groove corresponding to the circumferential ridge of the housing member, the circumferential groove rotatably engaging the circumferential ridge.

10. The surgical access device according to claim 2, wherein the first member of the lever conforms to a contour of an outer surface of the housing member.

11. The surgical access device according to claim 2, wherein the second member of the lever conforms to a contour of an outer surface of the rotor.

12. The surgical access device according to claim 1, wherein the port is connected to at least one of a fluid supply or a vacuum source.

13. A surgical access device comprising:

a cannula including a housing and a tubular member extending from the housing, the housing including a port in communication with the tubular member, the port connected to a fluid supply or a vacuum source, the cannula defining a lumen therethrough; and

a rotatable hub defining a passage therethrough, the rotatable hub including a first portion rotatably disposed within the housing and defining a bore and a second portion at least partially surrounding the tubular member, the second portion being disposed exterior to the housing of the cannula, wherein rotation of the second portion causes concomitant rotation to the first portion between an open position in which the bore is aligned with the port providing a fluid communication between the port and the tubular member and a closed position in which the first portion closes off the port, wherein the lumen of the cannula and the passage of the rotatable hub are in communication to receive a surgical instrument therethrough independent of a rotational position of the rotatable hub, wherein the port is stationary during transition of the first portion of the rotatable hub between the open and closed positions.

14. The surgical access device according to claim 13, wherein the rotatable hub includes a nub radially extending from an outer surface of the rotatable hub.

15. The surgical access device according to claim 14, wherein the housing defines a partially circumferential groove, the nub of the rotatable hub slidably engaging the partially circumferential groove.

16. The surgical access device of claim 15, wherein the partially circumferential groove defines a 90-degree angle.

17. The surgical access device according to claim 13, wherein the first portion of the rotatable hub defines a circumferential groove.

18. The surgical access device according to claim 17, wherein the housing includes a circumferential ridge radially extending from an inner surface of the housing, the circumferential groove of rotatable hub rotatably engages the circumferential ridge of the housing.
