Embodiment Construction

[0023] How the device works

[0024] The present invention first uses B-ultrasound positioning (X-ray, CT positioning can also be used) to determine the treatment site and area during operation, and inject the prepared microbubble reagent into the patient’s peripheral blood vessel or inject the microbubble reagent through an interventional cannula The position to be treated is then irradiated with low-frequency and low-power ultrasound to the treated part or area. The method of ultrasound microbubble contrast agent injection is used as a capillary embolization agent. Under the guidance of CT or B-ultrasound, the area that needs to be embolized is determined, such as a tumor area. The ultrasound energy is directly filled with ultrasound microbubble contrast through the contacting body surface Ultrasonic energy is delivered to the area of ​​the agent, and the capillary will form an embolism.

[0025] The ultrasonic power source device of the present invention is in the pri...

Abstract

An apparatus for using ultrasonic microvesicle contrast medium to generate the thrombus of chosen blood capillary is composed of an ultrasonic microvesicle contrast medium generating injector, a region locating unit for determining the position where thrombus is needed, and an ultrasonic therapeutic unit.

Description

1. Technical Field [0001] The invention relates to a method and device for setting a medical device for forming a capillary embolism with an ultrasonic microbubble contrast agent. It is especially used to locate and target the area to form capillary embolism to treat tumors and malignant tumors. 2. Background technology [0002] Ultrasonic microbubble contrast agent is currently a reagent used for ultrasound detection, mainly used for ultrasound myocardial imaging, see "Effects of Ultrasonic Irradiation on the Stability of Acoustic Vibration Microbubbles", Zha Daogang et al., Journal of the First Military Medical University, 1999 Volume 19 of Issue 5, Contrast agent microbubble concentration and size are the most important factors affecting myocardial acoustic imaging. The study reported the use of 2×2×4 factorial analysis to analyze the influence of different ultrasound irradiation conditions on the concentration and diameter of contrast agent microbubbles, namely the individual...
