Abstract: An electrosurgical pencil for use in performing surgery on a surgical site includes a main body forming a handle grippable by user and having open front and rear ends. The pencil has a vent tube open at its forward end, and slidably mounted in the body. The tube is adjustable independently from a retracted position to various extended positions. An elongate electrode is mounted in the tube and independently slidable therein. The electrode is adjustable manually in its longitudinal direction from a retracted position to extended positions. A first conducting strip can be mounted in the vent rube in contact with the electrode. A second conducting strip can be mounted in the main body and is in sliding contact with the first strip in order to provide power to the electrode.

Abstract: An electrosurgical tool or pencil for use in performing surgery includes an elongate, non-conductive housing having an elongate passage extending from a front end. An elongate electrode is mounted in the passage and slidable therein and has an operating forward section, an insulated central section, and an non-insulated rear section. The electrode can be adjusted in its longitudinal direction by a user. A conducting member is mounted on the rear section of the electrode and an elongate conducting strip is fixedly mounted in the elongate passage adjacent one side of the electrode and parallel thereto. The strip is supported by the housing so as to be in electrical contact with the conducting member which is slidable relative to the conducting strip. A circuit board for controlling the tool's operation is mounted in the housing and connected to the conducting strip.

Abstract: A ventilating apparatus for a toilet comprises a toilet seat having a rear end and an interior surface extending around a central opening. A primary venting passageway is formed in the seat and extends from the rear end and along opposite side sections and has at least one vent outlet located at the rear end. Inlet apertures are distributed around the interior surface and are in fluid communication with the passageway. Two hinge mechanisms are provided to pivotally connect the rear end of the seat to the toilet bowl and at least one of these mechanisms includes a threaded connecting pin member having a further venting passageway extending therethrough. This further passageway has an upper end which can be sealingly connected to the outlet at the rear of the toilet seat. Another venting outlet located at the bottom end of the pin member can be connected to a vacuum source for withdrawing foul air by means of the venting passageways.

Abstract: A venting attachment for a toilet comprises a main body shaped similar to a toilet seat. The main body has a bottom, an inner wall and outer wall, which together define a channel, a frontal portion at a front end and frangible break line formations. The inner wall has a plurality of apertures defined therein in fluid communication with the channel. The outer wall has at least one vacuum port which is in fluid communication with the channel. The break line formations enable the frontal portion to be severed from a major rear portion of the main body. The attachment with or without the frontal portion can be mounted on the underside of the toilet seat. The frontal portion can be severed from the major rear portion when the toilet seat is open at its front end.

Abstract: An air suctioning and filtering device for use in an surgery plume evacuation system comprises a suction inlet, a filter connected in fluid communication with the suction inlet, a connector pipe connected in fluid communication with the filter, and a vacuum fan connected in fluid communication with the connector pipe to suction air into the suction inlet, through the filter, and through the connector pipe. An air by-pass inlet having a shutter valve mounted thereon permits air to be suctioned to the source of suction without ingressing into the suction inlet, when the shutter valve is in a standby position. A much smaller amount of air is suctioned through the auction inlet. In a full suctioning position, with the shutter valve closed over the air by-pass inlet, all of the air is suctioned into the suction inlet from an electrosurgical pencil.

Abstract: A suctioning toilet seat system comprises a main toilet seat body and a plurality of suctioning apertures disposed in the main toilet seat body. The plurality of suctioning apertures are in fluid communication with an outlet in the main toilet seat body. A hose connects the outlet in fluid communication with a fan. An optional filter means is connected in fluid communication with the outlet for filtering air suctioned by the fan.

Abstract: An electrosurgical cart for use during surgery to support a surgical smoke evacuator unit comprises a first shelf for receiving and retaining a surgical smoke evacuator unit thereon. There is a substantially upright frame for structurally supporting the first shelf. There is also a plurality of wheels for rolling contact with a floor. An electrical control panel is mounted the electrosurgical cart, for controlling the surgical smoke evacuator unit. An electrical cable permits the transmission of electrical signals from the electrical control panel to the surgical smoke evacuator unit. A throughpassage on the front of the electrosurgical cart permits the flow of air from the inlet on the cart via a corrugated flexible hose to the filter on the smoke evacuation unit located on the bottom shelf.

Abstract: An electrosurgical pencil comprises a main body portion forming a handle. A wire retaining passage is defined by the main body portion and has a wire-receiving opening and an electrode-receiving opening. A metal electrode tip is mounted at the electrode-receiving opening for engaging tissue in a surgical site to thereby coagulate the tissue. A wire enters the wire retaining passage is selectively connectable in electrically conductive relation through an electrical switch to the metal electrode tip. A substantially unobstructed airflow vent is defined substantially solely by the main body portion so as to extend from the electrode end to the exhaust end of the main body portion, and has an inlet disposed adjacent the electrode end of the main body portion and that is connected in fluid communication via the airflow vent to an outlet disposed adjacent the exhaust end of the main body portion.
