Smoke evacuation apparatus designed to provide safe and efficient filtration and evacuation of smoke plume generated by laser-surgical, electrosurgical, radiosurgical, and electrocautery devices. A filter assembly is removably mounted on a front panel of the apparatus housing and is thus easily accessible from the front side which typically faces the user. The filter assembly at its front is provided with a hose connector to which the suction hose of the system is conveniently attached, and the front of the filter assembly is configured with a symbol, such as a letter or number, that represents an identification of the system supplier or manufacturer, and the hose connector is mounted on that symbol identifier.

A swivel device for connection to an ESU pencil, an exhaust port of an ESU pencil with an integrated smoke evacuation system, or an exhaust port of an ESU pencil smoke evacuation shroud attachment includes a fixed member attached to a rotating member. The rotating member allows an electrical cord and/or vacuum tube to twist and coil freely during operation of an ESU pencil with or without the smoke evacuation system.

A swivel device includes an improved connection between an electro-surgical unit (ESU) pencil's smoke evacuation system and a vacuum tube. The swivel device includes a fixed member attached to a rotating member. The rotating member allows the stiff vacuum tube to twist and coil freely while preventing forced movement of the fixed member or the ESU pencil. The swivel device can be added to existing ESU pencils with smoke evacuation systems or it can be built into ESU pencils with smoke evacuation systems.

A hollow disposable sleeve suction retractor. The sleeve suction retractor is an ergonomically shaped combination suction/retractor instrument for holding and retracting tissues, suctioning tissue pieces, blood and fluids and a surgical smoke plume from an electrosurgery device all at the same time. The suction sleeve retractor is comfortable to hold securely and allows a surgeon a clear line of sight on an area of tissue dissection. It can be used without the need for having another hand (e.g., surgeon's or an assistant, etc.) sponge or separate suction devices in a wound. It is economical to purchase and does not have to be sterilized or autoclaved since it disposable.

This invention relates to a surgical smoke evacuation system for use in removing gases and smoke created in surgical procedures from within an insufflated surgical cavity. Such a system comprises a discharge assembly adapted to form a gases path, and having an end which in use is located within said surgical cavity so that gases and/or surgical smoke inside said cavity can pass out of said cavity and through said discharge assembly along said gases path, a flexible discharge limb having an operational site end and an outlet end, and a self-supporting wall defining a gases flow passage between said operational site end and said outlet end, in use said open operational site end sealingly connected to said discharge assembly so that said gases and/or surgical smoke can pass out of said discharge assembly and into said discharge limb, a filter connected in use to the outlet end of the discharge limb, at least part of said wall of the discharge limb formed from a breathable material, said breathable material allowing the passage of water vapour through the wall of the discharge limb without allowing the passage of liquid water or surgical smoke or other gases.

Universally adaptable evacuators are adaptable to all surgical fields, easy to apply and, in most cases, may be expanded and/or removed as necessary. A hollow tube including a fitting adapted for connection to a vacuum source and at least one smoke inlet is held in position with the smoke inlet proximate to a surgical wound. According to a preferred embodiment, a stapling tab extending from a flexible perforated tube is used to hold the evacuator in place around the periphery of a surgical incision. According to an alternative embodiment, a smoke evacuator attaches temporarily or permanently to a retractor or other surgical instrument. Standard tubing and couplers may be used and the assembly may be prepackaged in sterile condition and disposed after use.

The invention pertains to techniques or processes for managing surgical smoke. In one embodiment a suction apparatus evacuates the surgical smoke. For example, the suction apparatus may be arranged adjacent to an electrocautery electrode, which may generate smoke during operation, for evacuating smoke from a surgical site.

Embodiments of the present disclosure provide an apparatus and method for reducing surgical smoke. An exemplary apparatus includes trocar comprising a tubular hollow body circumscribing a cavity extending through a longitudinal axis of the trocar with a gasket at a first end and an exit port at a second end, the tubular hollow body comprising a first wall circumscribing the cavity and a concentrically spaced apart second wall. The apparatus further includes a first plate operable to maintain an electric charged disposed within the cavity on the first wall, and a second plate operable to maintain an electric charge disposed between the first wall and the spaced apart second wall.

The present invention provides a porous non mechanical valve which retards or prevents the passage of bodily fluids and is resistant to being occluded or blocked by exposure to the surgical fumes or aerosols encountered during surgical procedures.

The invention relates to a surgical smoke filter, and belongs to the field of medical equipment. The surgical smoke filter comprises a closed shell with an inlet and an outlet, wherein the inlet and the outlet are formed in two parallel opposite faces of the closed shell, the closed shell comprises a harmful gas filtering cavity and a carbon dioxide absorbing cavity in sequence from the inlet to the outlet, the outlet of the closed shell is covered with a first multi-hole plate, and the inlet and the outlet of the closed shell extend outward from the shell to form an air inlet tube and an air outlet tube respectively. The surgical smoke filter is compact in structure, convenient to use, easy to operate, economical, efficient and capable of effectively clearing away harmful particles and carbon dioxide in smoke generated in laparoscopic surgery at the same time, the harmful particles and the carbon dioxide in smoke are easy to recycle and destroy, and the surgical smoke filter meets the administrative regulation for disposable sterile medical apparatuses.

A system for improving imaging during a surgical procedure includes an image sensor coupled to a controller. The image sensor is coupled to capture a video, including a first image frame with a smoke occlusion due to surgical smoke, of the surgical procedure. The first image frame includes a plurality of pixels each having an imaged color representing a view of the tissue affected by the smoke occlusion. The controller stores instructions that when executed causes the system to perform operations. The operations include determining an estimated true color of each of the plurality of pixels. The estimated true color is closer to an unoccluded color of the tissue than the imaged color. The operations also include generating, in response to determining the estimated true color, a desmoked first image frame with a reduced amount of the smoke occlusion relative to the first image frame.
