  • Publication number: 20240423668
    Abstract: An apparatus and method for a stepped needle for an intraosseous device that uses the outer surface of the bone cortex as a reference point. Since the thickness of the bone cortex does not vary significantly between patients, the accuracy of needle placement can be improved. The device includes a needle with a stepped increase in outer diameter disposed along the needle shaft. The abrupt change in outer diameter provides a substantial increase in insertion force. The stepped increase prevents any further insertion into the bone cortex. Embodiments can include a tapered needle lumen for medullary access confirmation and an overtube that is rotatably and slidably engaged to protect surrounding tissues and prevent needle stick injuries. Further, a needle hub can be rotatable or slidable, and can transition an overtube to an extended position to prevent accidental needle stick injuries.

  • Publication number: 20240423693
    Abstract: Systems and methods for controlling a radiofrequency (RF) treatment are provided. In some embodiments, the method can include: performing, using a programmable controller, at least the following functions of: measuring an electrical energy flow through a grounding pad that is in contact with at least a portion of skin of a subject's skin; determining, based on the measured electrical energy flow, a heating factor that represents a measure of heat absorbed by the subject over a period of time in response to treatment of the subject with an electrical radiofrequency probe; and comparing the heating factor to a predetermined threshold. In response to determining from the comparison that the heating factor is approaching or greater than the predetermined threshold value, the method can include disabling the radiofrequency generator or changing the electrical energy flow such that the controller regulates the electrical energy flow using a closed loop feedback system.

  • Publication number: 20240423697
    Abstract: Systems described herein include a two-tip handpiece that delivers current from two sources at two different frequencies. Signals at different frequencies are absorbed differently in the body. Accordingly, both monopolar and bipolar systems using this two tip handpiece and dual-frequency signal can detect impedance (or other frequency dependent characteristics) of the target tissue at the tips while delivering treatment, which was not possible or practical using conventional systems.

    Abstract: A medical system includes a memory which stores a trained model, and a processor. The trained model is a model trained by training data including an endoscopic image and a contact state between a treatment tool and a tissue in the endoscopic image. The endoscopic image is captured by an endoscope which captures an image including the treatment tool and a tissue to be treated. The processor acquires the endoscopic image including the treatment tool and the tissue. The processor uses the trained model to detect, from the endoscopic image, the contact state between the treatment tool and the tissue as first information.
