Abstract

Various trocars and trocar supports are provided for allowing an insufflation port on the trocar to be coupled through the trocar support to an insufflation fluid. In one embodiment, the trocar includes a housing, a cannula extending through the housing, and an insufflation port projecting from the housing. A trocar support is provided having an opening that receives the insufflation port on the housing such that the insufflation port is unobtrusive during use and can be connected and disconnected rapidly.

Claims

1. A surgical system, comprising:

a trocar having a housing and a cannula extending distally from the housing, the housing and the cannula defining a tool pathway extending therethrough for receiving a tool, the housing including at least one seal configured to form a seal across the tool pathway and an insufflation port extending from the housing and in fluid communication with the tool pathway for delivering insufflation therethrough; and

a carrier configured to be mounted on a distal end of a surgical robotic arm, the carrier including an elongate member having a trocar support on a distal end thereof, the trocar support being configured to support the trocar in a substantially fixed position, and at least one of the elongate member and the trocar support including an opening formed therein for receiving the insufflation port on the trocar.

2. The system of claim 1, wherein the insufflation port is concealed by the opening.

3. The system of claim 1, wherein the trocar support extends substantially perpendicular to the elongate member.

4. The system of claim 1, wherein the opening extends through each of the trocar support and the elongate member.

5. The system of claim 1, wherein the trocar support includes first and second movable arms that are configured to engage the housing of the trocar therebetween.

6. The system of claim 5, wherein the housing of the trocar includes opposed grooves formed therein for seating the first and second movable arms.

7. The system of claim 5, wherein the opening is positioned between the first and second movable arms and is configured to receive the insufflation port on the trocar.

8. The system of claim 1, wherein the opening comprises a cut-out formed in a distal end of the elongate member.

9. The system of claim 1, wherein the insufflation port extends substantially parallel to the cannula, and wherein the opening is formed in an upper surface of the trocar support for receiving the insufflation port.

10. The system of claim 1, wherein coupling of the insufflation port to the opening mates the trocar to the trocar support for holding the trocar in a substantially fixed position.

11. The system of claim 1, wherein the insufflation port extends substantially perpendicular to the cannula, and wherein the opening is formed in a terminal end of the trocar support and is in communication with a pathway extending through the elongate member.

12. The system of claim 1, wherein the insufflation port includes a Bal-Seal.
