  • Patent number: 11452472
    Abstract: A miniaturized sensing probe and a manufacturing method thereof are provided. The miniaturized sensing probe includes: a probe substrate including a probe part and a circuit connection part; a sensor disposed on the probe part and electrically connected to the circuit connection part; and a needle unit used to accommodate the probe part of the probe substrate; wherein the sensor performs sensing when placed into an analyte through the needle unit and transmits a sensing signal through the circuit connection part. The miniaturized sensing probe of the present invention may be easily placed into the analyte without the use of other instrument or surgery. This means is of benefit to a clinician performing an early diagnosis on a patient with a peripheral vascular disease or monitoring the biological value of the muscle during surgery in real time.

  • Patent number: 10786618
    Abstract: The example systems, apparatus and methods use a local perfusion extracorporeal circuit (LPEC) for perfusing a local target region of a body, with a systemic perfusion extracorporeal circuit (SPEC) coupled to the core region of the vasculature using a peripheral placed loop to the body, and a control procedure to cause the local target region of the body to be at a specified pattern of temperature values that are different than the temperature of the core of the body.

  • Patent number: 10786326
    Abstract: A surgical image pickup system utilizes an adjustable lens set and a complex lens set to change the direction of the incident light emitted from the light source and the position of the surgical site on which the incident light projects. The eyepiece and the sensor have the same field of view and the same optical axis such that first image generated by the sensor and a second image generated by the eyepiece are the same. The sensor transmits the first image to the external display for display by wireless communication. By means of the foregoing configuration, the second image which doctor utilizes the eyepiece to see and the first image which the external display displays are the same, thereby facilitating the operation of surgery.

  • Publication number: 20170154418
    Abstract: A method is provided to label invisible fluorescence by a visible light. A surgeon gets rid of screen for direct observation without repeated location confirmations between surgical site and onscreen mark. Fluid movement of a fluorescent dye can be observed in a real-time mode. Through projecting a visible-light spot at a fluorescent area at real time, the surgeon observes the fluorescent area the visible-light spot projecting to. Hence, the problem that fluorescence imaging technology must rely on screen to see the location of the fluorescent area is solved. When a patient moves or fluorescent areas changes, an image sensor automatically adjusts an area labeled by a visible-light spot through changing a photographing area with a focus automatically set. In addition, the method adjusts a projecting angle of the visible-light spot with an initial mirror and a final mirror only. Adjustment of lens group is not required the saving money.
