  • Patent number: 11883088
    Abstract: Apparatus and associated methods relate to controlling electrical power of an electrotherapeutic signal that is provided to a biological tissue engaged by an electrosurgical instrument during a medical procedure. Electrical power—a product of a voltage difference across and an electrical current conducted by the engaged biological tissue—is controlled according to a therapeutic schedule. The electrotherapeutic schedule can be reduced or terminated in response to a termination criterion being met. In some examples, the termination criterion is a current characteristic, such as, for example, a decrease in current conducted by the engaged biological tissue. In some examples, the termination criterion is a biological tissue resistance characteristic, such as, for example, an increase in the biological tissue resistance that exceeds a predetermined delta resistance value.

  • Patent number: 11730534
    Abstract: A surgical system includes an end effector assembly, a motor assembly, an energy source, and a controller. The controller activates the motor assembly, once it is determined that tissue is present between jaw members of the end effector assembly, to move the jaw members from a spaced-apart position to an approximated position to grasp tissue. The controller further activates the energy source, once tissue is grasped between the jaw members, to supply energy to the jaw members to seal tissue grasped between the jaw members. The controller further activates the motor assembly, once it is determined that tissue sealing is complete, to move the jaw members from the approximated position to the spaced-apart position to release sealed tissue. The system may further be configured to cut tissue once it is determined that tissue sealing is complete but before moving the jaw members to the spaced-apart position.

  • Patent number: 11684405
    Abstract: An apparatus (14) for supplying a medical instrument (15) for the treatment of biological tissue (11) due to the action of a plasma (28) is disposed, in accordance with the invention, in a special manner for the ignition and the stable development of a plasma (28) on the electrode (27) of the instrument (15). To accomplish this, the apparatus (14) comprises a control device (23) that, during an ignition test, limits—preferably in an instrument-specific manner—the current deliverable to the instrument (15) and/or limits the electrical power to be output to the instrument (15), and/or, in doing so, works with a reduced operating voltage. With this measure, a rapid, stable plasma development with minimal spark play is achieved with a large variety of connectable instruments (15a-15e).

  • Patent number: 5672179
    Abstract: An intubation device and a method of intubating a patient with an endotracheal tube is disclosed. The device comprises a housing and a flexible, tubular sheath having one end connected to the housing and a free end extending away from it. The sheath, which is adapted to fit within the endotracheal tube, also has a special light at the end of the sheath's free end for selectively providing illumination. In use, the sheath is inserted into the endotracheal tube until the light is at the end of the distal end of the tube. A clamp on the intubation device then clamps the endotracheal tube to the housing to prevent relative movement between the tube and the sheath. A tube stop is then slid along the sheath into abutting contact with the proximal end of the endotracheal tube to identify the location on the sheath corresponding to the proximal end of the tube. When the tube is properly positioned in the patient, the light will create a distinct glow visible to an observer in the area of the sternal notch.
