Insufflation circuit and filter

Disclosed herein is a surgical cannula configured as an instrument retaining or centering apparatus, configured for providing insufflation gases to a surgical cavity of a patient (such as the pneumoperitoneum) and allowing insertion of medical instruments into the surgical cavity through the cannula. The cannula can include features to direct gas flow in particular directions to prevent or reduce smoke, fog/condensation, or other unwanted media from contacting a portion of a medical instrument.

Directed gas flow surgical cannula for providing gases to a patient

A system is provided for delivering gas to a patient during a medical procedure. The system comprises a heater arranged to heat at least one of the gas and a humidification liquid. The system comprises a controller arranged to control the system according to a first mode during delivery of a first flow rate of gas and a second mode during delivery of a second flow rate of gas. The controller monitors an electrical characteristic of the heater to select the mode of operation and/or to determine an operating state of the system.

Methods and systems for delivering gas to a patient

Filters for surgical procedures including a fluid pathway to transport fluid, such as smoke and/or gases, exhausted from a surgical site, a humidity regulating element located along the fluid pathway, and a filter element located downstream of the humidity regulating element such that the humidity regulating element and the filter element are in fluid communication with each other. The humidity regulating element is configured to remove or reduce humidity from the smoke and/or gases exhausted from the surgical site prior to the smoke and/or gases reaching the filter element. The filter element is configured to filter particulate matter from the smoke and/or gases exhausted from the surgical site.

Filter for a humidification system

In one embodiment, a filter assembly for use in an insufflation system is described. The filter assembly comprises: a filter medium operative to filter medical gases; a housing comprising an inlet, an outlet and the filter medium, the housing defining a gases flow path through the filter medium between the inlet and the outlet; and at least one heating element being positioned in the housing and being configured to heat the filter medium; and wherein, the at least one heating element is spaced apart from the filter medium and from an inner surface of the housing.
