Problems solved by technology

However, there are still many deficiencies in this method at present, for example, it is difficult to distinguish lesions near the valve annulus, the determination of the voltage thresholds of normal, ischemic and infarcted myocardium remains to be clarified, and only using the voltage amplitude as the only discriminant index will miss other useful parameters. Information, the judgment of tissue lesions and the accuracy of the positioning system are not enough, and the need for complex workstation software systems, high prices, etc. also limit the popularization and application

Embodiment 1

[0029] Embodiment 1 The combined method of interventional ultrasonic positioning delivery and ultrasonic irradiation includes the following steps:

[0030] Set up a multifunctional ultrasonic catheter carried by the interventional catheter, and combine different types and numbers of transducers according to needs. According to different detection locations and purposes, the ultrasonic transducers installed on the top of the multifunctional ultrasonic catheter can be set to different sizes and shape, form different (ring, sector, rectangular, etc.) emitting surfaces and irradiation surfaces, extend the multifunctional ultrasound catheter to the detected part, and collect ultrasound image information and Doppler information at all levels of the target tissue, and the original radio frequency Information, etc., the acquired original information is input into the CPU of the host, and the corresponding analysis software and image processing system on the host are started according t...

Embodiment 2

[0032] Embodiment 2, the ultrasonic irradiation process method of entering the cardiovascular cavity comprises the following steps:

[0033] 1. Establish a multifunctional ultrasound catheter that meets the requirements of cardiovascular intervention

[0034] There are strict size requirements for entering the cardiovascular cavity. For example, the outer diameter of the multifunctional ultrasonic catheter entering the arterial system is required to be within 8F (2.67mm), generally within 7F (2.33mm), and can achieve 16 or more crystal array ultrasound imaging. The basic goal is that the above-mentioned crystal arrays are arranged in a small convex formation. There is a 0.4mm hole in the multifunctional ultrasonic catheter, which allows the 0.35mm guide wire and the 0.3mm micro-injection needle to pass through. The multi-functional ultrasound catheter head enters the detection ultrasound detection area behind. There is still a small area at the tip of the catheter for the pl...

Embodiment 3

[0043] Example 3: Diagnosis and Treatment Process of Ultrasonic Radiation into Other Viscera

[0044] (1) Establish the above-mentioned multifunctional ultrasound catheter. The size of the transducer on the catheter depends on the organ it enters. For example, the size of the catheter entering the bladder and renal pelvis is similar to the above-mentioned catheter entering the cardiovascular cavity, while entering the cavity such as the uterus For larger organs, the size of the multifunctional ultrasound catheter can be similar to the size of the head of the hysteroscope. The number, shape, and mode of emitting and obtaining ultrasound at the front end of the multifunctional ultrasound catheter can be changed according to the different organs and purposes.

[0045] (2) The operation process is the same as clinical cystoscopy and hysteroscopy, but a certain amount of normal saline should be injected in advance to make the multifunctional ultrasonic catheter immersed in water to ...

Abstract

The insertion type ultrasonic in-tissue locating, delivering and irradiating method includes establishing multifunctional ultrasonic duct capable of acquiring different ultrasonic signals simultaneously and setting ultrasonic imaging transducer, ultrasonic irradiating transducer and micro needle hole in the end of the duct; acquiring different kinds of ultrasonic image information with ultrasonic imaging transducer; ultrasonic image monitoring and directing the pierce position and depth in tissue of the injecting needle and / or the ultrasonic irradiation of the ultrasonic irradiating transducer on the tissue. An ultrasonic locating injection and irradiation instrument is also disclosed, which may be used to complete ultrasonic image data acquisition and accurate delivering of treating matter to deep pathological tissue and raise the ultrasonic treatment effect by means of the ultrasonic biological effect.

Description

technical field [0001] The present invention relates to interventional ultrasound real-time information acquisition and positioning technology, relates to targeted delivery under the guidance of interventional ultrasound real-time imaging positioning and the technology of releasing acoustic energy to target tissue for ultrasonic irradiation to enhance the curative effect of delivery, and realizing the technical solution Integrated interventional ultrasound positioning injection irradiator. The interventional ultrasonic positioning injection irradiation instrument is a new type of positioning and delivery tool. It has a multifunctional ultrasonic catheter for obtaining different ultrasonic information. Doppler imaging, Doppler energy map and other aspects can comprehensively obtain image information, guide the retractable micro-needle attached to the ultrasound machine to accurately deliver substances to different layers of tissue in the target area, and / or at the same time, th...
