  • Patent number: 10595930
    Abstract: Aspects of the present disclosure include a surgical device comprising electrodes on the sides of an end of an effector to aide in sealing during various surgical procedures, such as a liver resection. During a sealing procedure, the surgeon may wipe the surgical site with the end effector, causing the electrodes to touch the fractured area. Electrosurgical energy may be applied to the electrodes during the wiping, causing coagulation of smaller vessels, such as tiny blood vessels and bile ducts in the parenchyma of the liver. In some cases, due to the nature of some smaller vessels, electrosurgical energy should be delicately applied to cause sealing but to avoid overly damaging the remaining tissue. In some embodiments, the thin design of the electrodes allows for an appropriate amount of electrosurgical energy to be applied to the fractured area.

  • Patent number: 6797924
    Abstract: The present invention provides a soldering iron with a graphite tip having two separate halves that are electrically isolated from one another. The tip halves are each electrically connected to the opposite sides of an electrical power source. When both halves of the tip are applied to an electrically conductive material, such as the material to be soldered, an electrical circuit between the tip halves and electrical power source is completed. The halves are of the tip are constructed from material semi-conductive electrically and having high thermal conductivity. Therefore, the tip can reach operating temperatures quickly. When the tip is removed from the joint, the electrical circuit is broken and the tip material may quickly cool to a temperature safe for human contact. Because electricity is only able to flow when the two pieces of the tip are electrically connected, no separate switch is required.

  • Patent number: 4559437
    Abstract: An air assisted hand welding tool for clamping and welding conductors together. The tool includes a handle formed of pivotally connected lever-like members. An air passage is connected to an air pressure source provided in the handle of the hand tool. A valve is manually engaged by the operator (following tactile closing of the electrodes on the conductors) to open the air pressure to an expansion chamber formed between the members. As the chamber pressure is increased, the members are urged to a consistent clamping force thereby to assist the operators normal hand clamping function. A switch in the expansion chamber is connected to the welding circuit and is activated following chamber expansion to initiate welding. The entire welding operation including air assist and welding current initiation are all accomplished by a simple closing motion of the operators hand.
