  • NEEDLE PROBE, APPARATUS FOR SENSING COMPOSITIONAL INFORMATION, MEDICAL DRAIN, METHOD OF MEASURING A THERMAL PROPERTY, AND METHOD OF SENSING COMPOSITIONAL INFORMATION
    Publication number: 20220225890
    Abstract: The invention relates to sensing compositional information about material by measuring thermal properties of the material. In one arrangement there is provided a needle probe for sensing compositional information. The probe comprises a needle having a tip region. A resistive element is attached to the needle at the tip region. A measurement system is configured to: 1) drive an electrical current through the resistive element to apply heating to the resistive element, and 2) measure an electrical response of the resistive element to the heating. A processing unit analyses the measured electrical response of the resistive element to the heating to determine compositional information about material in contact with the tip region.

  • ELECTROSURGICAL APPARATUS AND METHOD
    Publication number: 20220000535
    Abstract: Apparatus and methods for electrosurgery are disclosed. In one arrangement, an electrosurgical element and a control system are provided. The electrosurgical element is electrically driven in a first electrical driving mode. The first electrical driving mode is such as to cause heating of human or animal tissue by the electrosurgical element. The heating contributes to modification or cutting of tissue by the electrosurgical element. The electrosurgical element is electrically driven in a second electrical driving mode. An electrical response of the electrosurgical element is measured during the electrical driving of the electrosurgical element in the second electrical driving mode.
