The present invention relates to an improved smoke evacuation device for use in laparoscopic surgeries. One improvement is a hydrophilic wick positioned within the inlet system of the smoke device for absorbing moisture and trapping surgical waste entering the smoke evacuation device. The second improvement is a multi-outlet valve inserted into the outlet system of the smoke evacuation device to enable quick depressurization of the surgical site.

Wick and relief valve for disposable laparoscopic smoke evacuation system

A filter body having a housing, a cavity for holding a filter media, intake ports each configured to receive an intake tube, and a plurality of intake port flaps configured for movement between a first position which restricts passage of a gas or liquid and a second position which allows passage of a gas of liquid. In one aspect, a filter body has flaps that have a magnet and the housing has an attracting material configured to attract the magnet in at least one of the flaps and configured to hold a flap in the first position. In another aspect, a filter in which a portion of the housing comprises an attracting means is configured to hold a flap in the first position. In another aspect, a filter having a housing configured to hold a filter media has a plurality of fluid passage holes and hole covers, in which the hole covers and an area adjacent to the holes on the filter housing each have an attracting material for holding the hole covers in a position.

Air recirculation system with filter flaps

An evacuation system includes at least one fluid intake, at least one fluid outlet, at least one operational component such as an evacuation motor, and a first read/write device such as an RFID tag for transmitting, receiving, or storing information. The evacuation system also includes a filter having a second read/write device for transmitting information to the first read/write device. A microcontroller, which is in functional communication with the first read/write device and the operational component, interprets the information received by said first read/write device and controls the operational component based on said interpreted information.

Fluid evacuation system with two-way communication filter

A service head for use in connection with a medical procedure in an enclosure such as an operating room. In one aspect, a service head comprises a filter adapted to be punctured by a timing pin in connection with the determination and/or communication of filter life. In another aspect, a service head comprises and RFID tag and RFID reader in connection with the determination and/or communication of filter life. In another aspect, a service head comprises wireless communication components for communicating with a surgical assembly such as an ultrasonic surgical device, electrocautery device, insufflator, laser surgical instrument, camera, surgical light source or endoscopic device.

Operating room smoke evacuator with integrated vacuum motor and filter

An evacuation system includes at least one fluid intake, at least one fluid outlet, at least one operational component, such as an evacuation motor, and a first read/write device for transmitting, receiving, or storing information. The evacuation system also includes a filter having a second read/write device for transmitting information to the first read/write device. A microcontroller, which is in functional communication with the first read/write device and the operational component, interprets the information received by said first read/write device and controls the operational component based on said interpreted information.

The present invention broadly comprises a multiport filter having at least three intake ports and at least two layers&#x2014;a first layer for containing particles 3 microns or greater and a second layer that contains particles 3 microns or less in size. In alternate embodiments, the filter includes a third layer for trapping odors and gases and a fourth layer for trapping fines. The second layer may be comprised of ULPA material and may have antimicrobial material. The invention also includes a contaminant removal system for the filtering and recirculation of air contaminated with smoke from cautery-type surgical procedures. The invention also broadly comprises a surgical assemblies control service head designed to house powered surgical devices and a vacuum-filtering system for the treatment of air contamination caused by surgical procedures.

A combined smoke evacuation and filter apparatus adapted to receive and hold a surgical device which may produce smoke such as a cauterization pencil or a laser device, and which apparatus can be connected to a vacuum source. The apparatus includes a unitary holder formed of elastic material, a suction tube carrying the power line of the device, a tubular plastic back end piece connecting the holder to the suction tube, and a filter housing at an end of the suction tube. The filter housing contains a four stage filter and a casual liquid collector. The unitary holder has a cradle, a conically shaped portion, and an oval shaped lumen located below the cradle for carrying the smoke to the end piece. The tubular back end piece is provided with a retaining fork which bears against the proximal end of the device, the elastic holder being stretched when the parts are assembled.
