Abstract

An apparatus for allowing simultaneous use of at least two surgical instruments through a single incision. The apparatus includes a first part having a proximal end, a distal end, an inner surface and an outer surface. The outer surface engages an incision and holds the incision in an open position. The inner surface defines a passageway through the first part from the proximal to the distal ends. The apparatus also includes a second part attached to the proximal end of the first part for sealing the proximal end of the first part and having at least two ports for receiving a surgical instrument. At least one of the ports includes a ball joint to allow articulation of the port relative to the second part. The ball joint allows the orientation of the port and the surgical instrument within it to be moved easily relative to the apparatus.

Claims

1. An apparatus for allowing simultaneous use of at least two surgical instruments through a single incision, the apparatus comprising:

a first part having a proximal end, a distal end, an inner surface and an outer surface, wherein the outer surface is for engaging an incision and holding the incision in an open position and the inner surface defines a passageway through the first part from the proximal to the distal ends; and

a second part attached to the proximal end of the first part for sealing the proximal end of the first part and comprising at least two ports for receiving a surgical instrument, and wherein at least one of the ports comprises a ball joint to allow articulation of the port relative to the second part.

2. An apparatus according to any claim 1, wherein each port further comprises a valve for sealing the surgical instrument, and wherein if the port comprises a ball joint, the valve is positioned separate from the ball joint.

3. An apparatus according to claim 1, wherein the ball joint comprises sealing fins located in the socket.

4. An apparatus according to claim 1, wherein the second part is releasably attached to the first part.

5. An apparatus according to claim 4, wherein the first part and/or the second part is reusable.

6. An apparatus according to claim 4, wherein the first part is adapted for insertion into an incision using a trocar.

7. A system comprising:

an apparatus according to claim 6; and

a trocar arranged to releasably attach to the proximal end of the first part, for inserting the first part into an incision.

8. An apparatus for allowing simultaneous use of at least two surgical instruments through a single incision, the apparatus comprising:

a first part having a proximal end, a distal end, an inner surface and an outer surface, wherein the outer surface is for engaging an incision and holding the incision in an open position and the inner surface defines a passageway through the first part from the proximal to the distal ends; and

a second part attached to the proximal end of the first part for sealing the proximal end of the first part and comprising at least two ports for receiving a surgical instrument, and wherein at least one of the ports comprises a ball joint to allow articulation of the port relative to the second part;

wherein the ball joint comprises a socket and the ball joint further comprises at least one ridge or sealing fin located within the socket.

9. An apparatus according to claim 8, wherein each port further comprises a valve for sealing the surgical instrument, and wherein if the port comprises a ball joint, the valve is positioned separate from the ball joint.

10. An apparatus according to claim 8, wherein the ball joint comprises sealing fins located in the socket.

11. An apparatus according to claim 8, wherein the second part is releasably attached to the first part.

12. An apparatus according to claim 11, wherein the first part and/or the second part is reusable.

13. An apparatus according to claim 11, wherein the first part is adapted for insertion into an incision using a trocar.

14. A system comprising:

an apparatus according to claim 13; and

a trocar arranged to releasably attach to the proximal end of the first part, for inserting the first part into an incision.
