Embodiment 1

[0054] Example 1: Multi-frequency Focused Ultrasound Therapy System

[0055] The present invention takes the ultrasonic treatment system as embodiment 1 to illustrate the implementation of the ultrasonic treatment system.

[0056] The ultrasonic therapy system is a system used to receive, process and send therapeutic ultrasonic signals and data, and control the output of therapeutic ultrasonic waves according to control instructions. There are two purposes for designing an ultrasonic therapeutic system. On the one hand, it completes the measurement of relevant parameters in a specific state, so that It provides information for ultrasonic therapy; on the other hand, it controls the therapeutic ultrasonic wave based on the ultrasonic therapy system.

[0057] Functionally, the ultrasonic treatment system can be divided into main control module 001, temperature measurement module 002, treatment site guidance module 003, pulse duty ratio adjustment module 004, power adjustment modu...

Embodiment 2

[0074] Example 2: Ultrasonic irradiation of hematoporphyrin to kill tumor cells

[0075] 1. Equipment

[0076] 1. Experimental group equipment:

[0077] Focused ultrasound non-invasive treatment system is used as the ultrasonic power source, and the focused ultrasonic transducer emits two groups of focused ultrasonic waves with different frequencies (250KHz and 800KHz) synchronously.

[0078] 2. Control group equipment:

[0079] A plastic test tube that does not emit ultrasonic waves was used as a control group.

[0080] 2. Experimental environment and experimental materials

[0081] 1. Experimental environment

[0082] A sound-absorbing water tank (200×200×100) cm was used as the experimental site. The water tank was filled with deionized water, and the fixed brackets in the water tank were used to place plastic test tubes.

[0083] 2. Experimental materials

[0084] Human tumor cells K562 were collected by culturing, respectively placed in plastic test tubes filled wit...

Abstract

The invention discloses a focused ultrasonic noninvasive sound powered tumor therapy system. The system is characterized in that: a photosensitizer and an ultrasonic micro bubble contrast medium are used as tumor therapy media, the photosensitizer and the ultrasonic micro bubble contrast medium are injected respectively before a patient is treated, an ultrasonic diagnosis probe is used for detecting a therapeutic part and performing stereo positioning, and a multi-frequency focused ultrasonic transducer is used for transmitting low-power multi-frequency ultrasonic to excite the photosensitizer to generate photochemical reaction in the tumor cells and induce the ultrasonic micro bubble contrast medium to generate an acoustic cavitation effect around the tumor tissues, so that tumor microcirculation embolism is caused, tumor cell transfer is prevented, and the system plays a good role in noninvasive tumor therapy.

Description

Technical field [0001] The invention belongs to the field of medical equipment, and more specifically the invention relates to a focused ultrasound non-invasive sonodynamic tumor treatment system. Background technique [0002] Malignant tumors are the main cause of death in the human body. Although there are many technologies for treating malignant tumors, tumor surgery, radiotherapy and chemotherapy are still the main treatments for malignant tumors. How to kill residual tumor cells after surgery and reduce tumor cells Diffusion and metastasis, improving the sensitivity and therapeutic effect of radiotherapy are research areas of common concern in the medical community. [0003] Photodynamic tumor therapy uses laser to excite photosensitizers to generate singlet oxygen, which can destroy the microstructure and substructure of tumor cells through the powerful oxidation ability of singlet oxygen, thereby exerting anti-tumor function. It has no special affinity and can be aut...
