    Abstract: Systems and methods for estimating tissue parameters, including mass of tissue to be treated and a thermal resistance scale factor between the tissue and an electrode of an energy delivery device, are disclosed. The method includes sensing tissue temperatures, estimating a mass of the tissue and a thermal resistance scale factor between the tissue and an electrode, and controlling an electrosurgical generator based on the estimated mass and the estimated thermal resistance scale factor. The method may be performed iteratively and non-iteratively. The iterative method may employ a gradient descent algorithm that iteratively adds a derivative step to the estimates of the mass and thermal resistance scale factor until a condition is met. The non-iterative method includes selecting maximum and minimum temperature differences and estimating the mass and the thermal resistance scale factor based on a predetermined reduction point from the maximum temperature difference to the minimum temperature difference.

  • Publication number: 20190083171
    Abstract: A surgical instrument includes a reusable component and a limited-use component releasably engagable with the reusable component. The reusable component includes a detecting member and is configured to connect to a source of energy. The limited-use component is transitionable from a first state to a second state. The detecting member is configured to detect a response of the limited-use component for determining the state of the limited-use component. Energy is permitted to be supplied to the limited-use component when it is determined that the limited-use component is disposed in the first state. Energy is inhibited from being supplied to the limited-use component when it is determined that the limited-use component is disposed in the second state.

    Abstract: An electrosurgical instrument is provided and includes a housing configured to connect to a source of bipolar electrosurgical energy and an electrode body coupled to the elongated housing. The electrode body includes an electrode face, first and second bipolar electrodes and a blade. The electrode face is formed on the distal end of the electrode body and includes a longitudinal axis and a transverse axis therethrough. The first and second electrodes have a leading edge and a trailing edge, are formed on opposite sides of the longitudinal axis and connect to opposed electrical potentials. The blade is positioned between the electrodes with at least a portion of the blade extending beyond the electrode face.

  • Publication number: 20190083173
    Abstract: An irrigated ablation catheter includes a shaft and an electrode assembly affixed to a distal end of the shaft. The distal electrode assembly includes a manifold and an ablation electrode affixed together and extending along a center axis. The electrode has a distal irrigation passageway extending therethrough to an opening at a distal tip of the electrode. The opening of the irrigation passageway is offset in distance from the center axis, and allows a thermal sensor such as a thermocouple to be located in a sensor cavity in the electrode on or near the center axis. One variation involves providing a pair of distal irrigation passageways through the electrode where both of the openings of the passageways are offset from the center axis. The thermal sensor in this variation is located in the sensor cavity substantially on the center axis.

    Abstract: Aspects of this disclosure pertain to a device with an elongated body having a distal end. The distal end may comprise a port that permits discharge of a laser energy towards a tissue from an optical fiber located in the distal end. An exterior surface of the distal end may include a cauterization portion that permits discharge of a cauterization energy towards the tissue. In some aspects, the device includes an insulative portion that attaches the distal end to the elongated body and limits energy transfer therebetween. Related systems and methods are also disclosed.

    Abstract: A distal end of an optical fiber may be protected by a variety of alternative protective caps, tips, and/or sleeves. In one example, a generally cylindrical soft tip is arranged to fit over the end of the fiber, and to compress in an axial direction when pressed against a stone to allow a recessed tip of the fiber to contact the stone or to be maintain a minimum spacing between the fiber tip and the stone and thereby limit erosion of the fiber tip.

  • Publication number: 20190083178
    Abstract: A C-arm, or a mobile intensifier device, is one example of a medical imaging device that is based on X-ray technology. Because a C-arm device can display high-resolution X-ray images in real time, a physician can monitor progress at any time during an operation, and thus can take appropriate actions based on the displayed images. Monitoring the images, however, is often challenging during certain procedures, for instance during procedures in which attention must be paid to the patient's anatomy as well as a medical imaging device display. In an example, a surgical instrument assembly includes a processor, a surgical instrument configured to operate on an anatomical structure, and a display coupled to the processor and attached to the surgical instrument. The display can be configured to display visual information comprising X-ray images generated by a medical imaging device.

    Abstract: The present technology relates to a medical image processing apparatus, a medical image processing method, and a program that make it possible to accurately detect a surgical tool. The medical image processing apparatus includes: an imaging unit that images an object on which a luminescent marker is arranged; and a processing unit that processes an image captured by the imaging unit, in which the processing unit extracts a color emitted by the luminescent marker from the image, and detects a region in the image in which the extracted color is distributed as a region in which the object is located. Moreover, the processing unit calculates chromaticity for each of pixels in the image, extracts a pixel having chromaticity corresponding to an emission color of the luminescent marker, and detects the extracted pixel as a region in which the object exists.
