Abstract

A system for performing an endoscopic surgical procedure in a surgical cavity is disclosed which includes a primary gas circulation device housing a central processor and a primary pump, the primary pump controlled by the central processor and configured to deliver a flow of pressurized gas to a primary gas delivery lumen and to receive gas from a primary gas return lumen, and a plurality of subordinate gas circulation devices each housing a respective subordinate pump configured to deliver a flow of pressurized gas to a respective subordinate gas delivery lumen and to receive gas from a respective subordinate gas return lumen, wherein the subordinate pump in each subordinate gas circulation device is in networked communication with and controlled by the central processor of the primary gas circulation device.

First claim

1 . A system for performing an endoscopic surgical procedure in a surgical cavity, comprising:
a) a primary gas circulation device housing a primary pump configured to deliver a flow of pressurized gas to a primary gas delivery lumen and to receive gas from a primary gas return lumen; b) a primary gas sealed access port configured to receive pressurized gas from the primary gas delivery lumen to generate a gaseous seal therein and to return gas used to generate the gaseous seal back to the primary pump through the primary gas return lumen, so as to maintain a stable pressure level within the surgical cavity, wherein the primary gas sealed access port is a single lumen gas sealed access port that includes a single tubular body portion; c) at least one subordinate gas circulation device in communication with and controlled by the primary gas circulation device and housing a subordinate pump configured to deliver a flow of pressurized gas to a subordinate gas delivery lumen and to receive gas from a subordinate gas return lumen; and d) at least one subordinate gas sealed access port configured to receive pressurized gas from the subordinate gas delivery lumen to generate a gaseous seal therein and to return gas used to generate the gaseous seal back to the subordinate pump through a subordinate gas return lumen.

2 . A system as recited in claim 1 , wherein the primary gas circulation device further houses an insufflator for delivering insufflation gas to the surgical cavity through an insufflation lumen and periodically measuring pressure within the surgical cavity through the insufflation lumen.

3 - 4 . (canceled)

5 . A system as recited in claim 1 , further comprising an insufflation sleeve for receiving insufflation gas from the insufflator through an insufflation lumen, wherein the insufflation sleeve defines a central bore for receiving the single tubular body portion of the primary gas sealed access port so that an insufflation passage is defined between an inner surface of the insufflation sleeve and an outer surface of the tubular body portion.

6 . A system as recited in claim 1 , wherein the single lumen gas sealed access port has a separable two-part housing including a lower housing portion connected to the single tubular body portion and an upper housing portion releasably attached to the lower body portion.

7 . A system as recited in claim 6 , wherein the lower housing portion includes structure to facilitate manipulation by a robotic surgical system during a robotically assisted endoscopic surgical procedure.

8 . A system as recited in claim 1 , further comprising a valve sealed access device for receiving insufflation gas from the insufflator through the insufflation lumen.

9 . A system as recited in claim 1 , further comprising an insufflation needle for receiving insufflation gas from the insufflator through the insufflation lumen.

10 . A system as recited in claim 1 , further comprising a primary filter cartridge configured for reception in the primary gas circulation device to communicate with the primary gas delivery lumen and the primary gas return lumen.

11 . A system as recited in claim 2 , further comprising a primary filter cartridge configured for reception in the primary gas circulation device to communicate with the primary gas delivery lumen, the primary gas return lumen and the insufflation lumen.

12 . A system as recited in claim 1 , wherein the at least one subordinate gas circulation device includes a subordinate filter cartridge communicating with the subordinate gas delivery lumen and the subordinate gas return lumen.

13 . A system as recited in claim 1 , wherein the primary gas circulation device includes a data reader for detecting a machine readable data signature of a primary filter cartridge received therein to determine a physical characteristic of the cartridge and/or number of lumens associated therewith.

14 . A system as recited in claim 1 , wherein the at least one subordinate gas circulation device includes a data reader for detecting a machine readable data signature of a subordinate filter cartridge received therein to determine a physical characteristic of the cartridge and/or number of lumens associated therewith.

15 . A system as recited in claim 1 , wherein the primary gas circulation device houses a central processor for controlling the primary pump of the primary gas circulation device and the subordinate pump of the at least one subordinate gas circulation device.

16 . A system as recited in claim 15 , wherein the subordinate pump of the at least subordinate gas circulation device is driven by AC power.

17 . A system as recited in claim 15 , wherein the subordinate pump of the at least subordinate gas circulation device is driven by a DC motor.

18 . A system as recited in claim 15 , wherein the at least one subordinate gas circulation device is in wireless communication with the central processor of the primary gas circulation device.

19 . A system as recited in claim 15 , wherein the at least one subordinate gas circulation device is in wired communication with the central processor of the primary gas circulation device.

20 . A system as recited in claim 15 , wherein a plurality of subordinate gas circulation devices are in networked communication with and controlled by the central processor of the primary gas circulation device.

21 . A system as recited in claim 20 , wherein each of the plurality of subordinate gas circulation devices is configured to deliver a flow of pressurized gas to a respective subordinate gas delivery lumen connected to a respective subordinate gas sealed access port and to receive gas from a respective subordinate gas return lumen connected to the respective subordinate gas sealed access port.

22 . A system as recited in claim 1 , wherein the at least one subordinate gas sealed access port is a single lumen gas sealed access port that includes a single tubular body portion.

23 . A system as recited in claim 22 , wherein the single lumen gas sealed access port has a separable two-part housing including a lower housing portion connected to the single tubular body portion and an upper housing portion releasably attached to the lower body portion.

24 . A system as recited in claim 23 , wherein the lower housing portion includes structure to facilitate manipulation by a robotic surgical system during a robotically assisted endoscopic surgical procedure.

25 . A system as recited in claim 15 , wherein the central processor of the primary gas circulation device is adapted and configured to conduct a multi-staged calibration process for calibrating a pneumatic performance range of the primary gas sealed access port and the at least one subordinate gas sealed access port.

26 - 30 . (canceled)

31 . A system for performing an endoscopic surgical procedure in a surgical cavity, comprising:
a) a single lumen gas sealed access port having a proximal housing portion containing an annular nozzle assembly for generating a gaseous seal within the proximal housing portion and a tubular body portion depending distally from the proximal housing portion; and b) an insufflation sleeve for defining a central bore for receiving the tubular body portion of the gas sealed access port so that an insufflation passage is formed between an inner peripheral surface of the insufflation sleeve and an outer peripheral surface of the
