Abstract: A faucet diverter assembly for dampening a pressure spike includes a body and a diverter bonnet assembled into the body defining a flow passageway therebetween. A diverter portion is assembled into the diverter bonnet and is axially movable by the use of an extender. The diverter portion includes and upper stem and a lower stem attached to the upper stem. Assembled onto the lower stem is a movable plunger that is spring biased by a spring positioned between the plunger and the upper stem. A return spring, received by the upper stem, acts between the upper stem and the diverter bonnet. When a pressure spike is encountered, the pressure force is sensed by the plunger by way of a flow inlet passage and movement of the plunger, in response to the pressure force, compresses the plunger spring, thereby functioning as a shock absorber.

Abstract: An operative laparoscopic instrument is equipped with proximal and distal loops closed by slip knots and tightenable from the proximal end of the instrument. A forceps extending from the distal end of the instrument grasps an anatomical tube to be both ligated and transected and pulls it into the instrument past both loops. The distal loop is first tightened to ligate the tube and the proximal loop is then tightened to transect the tube.

Abstract: A trocar assembly consisting of a trocar in a central opening in a cannula. The cannula is provided with at least one separate passage running parallel to the central passage. The separate passage is connected to a source of cleansing fluid and a pump for pumping fluid through the separate passage. The separate passage terminates in an orifice near the distal end of the central opening of the cannula. In operation, when the cannula is used to provide access for a laparoscope or other viewing instrument, the end of the viewing instrument may become clouded with moisture and other debris. In this case, the end of the viewing instrument may be withdrawn into the distal end of the cannula adjacent the fluid orifice. The pump is actuated and cleansing fluid is forced over the end of the instrument cleaning away the obstructing matter without removing the instrument from the cannula. Drying air can also be supplied to the instrument, either through the same or a different separate passage.

Abstract: A valve and cover plate construction for mounting a valve assembly in a plastic faucet cover plate and for securing the plate to a deck of a sink. The valve and cover plate construction comprise an annular seat formed inside of a flange in the cover plate in which the valve is disposed, a plastic split annular retaining washer adapted to be seated on annular seat, and an annular flange having an abutting surface on the bonnet of the valve assembly adapted to abut against the top of the retaining washer and press it against the seat when the valve assembly is inserted into the flange of the cover plate. The bonnet also has an annular flange having an undercut in its bottom into which is inserted a sealing member such as an O-ring. The sealing member is encapsulated on three sides by the material forming the bonnet.

In operation, when the cannula is used to provide access for a laparoscope or other viewing instrument, the end of the viewing instrument may become clouded with moisture and other debris.

Abstract: A device which can be used in a laparoscopic surgical procedure is disclosed. The device is to be used in the surgical procedure as a retractor i.e. to displace and hold internal organs of a patient away from the organ which is the surgical objective. The device, which is essentially a long thin narrow tube, is partially inserted into the abdomen of a patient through a tiny incision in the abdomen wall. Retractor action is accomplished by the movement of levers, slides or buttons located on the end of the tube that remains outside of the patient. These levers, slides or buttons control the opening or closing of components, such as finger-like protuberances, that depend from the end of the tube that is within the patient. These protuberances push and hold floppy organs away from the surgical objective so that the surgical team can clearly view the organ using the laparoscope and remove the organ with tiny laparoscopic instruments.

Abstract: A coupling flange for use on a power tool such as a portable grinder for transferring torque loads from the motor-driven spindle of the tool to a tool element subassembly such as an abrasive disc subassembly. The coupling flange is designed to accommodate and be usable with both hubbed and non-hubbed abrasive disc subassemblies. The coupling flange is adapted to be installed onto the spindle of the tool and comprises a first contact surface for frictionally engaging the spindle, and at least two radially spaced annular drive surfaces. The first drive surface is adapted to frictionally engage the backing flange of a hubbed-type of abrasive disc subassembly and the second drive surface is adapted to frictionally engage the backside of the abrasive disc of a non-hubbed type of abrasive disc subassembly.
