Abstract

A surgical gas delivery system is disclosed that includes a device housing supporting a control unit and a filter interface having a seat for receiving a filter cartridge, the filter cartridge having a filter housing defining an interior reservoir, wherein sensors are coupled to the control unit for sensing a level of liquid within the reservoir of the filter cartridge to prevent contamination of the device, and wherein a set of blocking valves are provided in the device housing for interacting with the filter cartridge when it is received in the filter interface to control flow through suction and pressure lines of the device, and wherein the control unit is adapted to recognize a characteristic of the filter cartridge received in the filter interface.

First claim

What is claimed is:

1. A surgical gas delivery system comprising: a) a gas circuit including a gas delivery device, wherein the gas circuit is monitored by a gas composition sensor; and b) a trocar in communication with the gas delivery device configured to provide access to a patient's abdominal cavity through a central bore, wherein atmospheric air from outside of the gas circuit is drawn into the patient's abdominal cavity through the central bore of the trocar during a surgical procedure as a result of gas leakage from the patient's abdominal cavity, in order to maintain a gas concentration in the patient's abdominal cavity at a predetermined level provided by the gas delivery device.

2. A surgical gas delivery system as recited in claim 1 , wherein the gas delivery device is a multimodal gas delivery device.

3. A surgical gas delivery system as recited in claim 1 , wherein the trocar is a gas sealed trocar.

4. A surgical gas delivery system as recited in claim 1 , wherein the gas composition sensor is adapted and configured to ensure gas quality in the patient's abdominal cavity during the surgical procedure.
