Abstract

The invention provides an ultrasound medium liquid level control device and focused ultrasound therapeutic equipment, belongs to the technical field of high-intensity focused ultrasound and can solvethe problem that existing high-intensity focused ultrasound has large demand for a liquid transfer medium and the height cannot be controlled. According to the ultrasound medium liquid level control device, a first opening of a negative pressure cavity extends into a container; the negative pressure cavity is controlled to keep negative pressure, so that an ultrasound medium in the container is pumped into the negative pressure cavity to submerge the top of a sound production surface. That is, the ultrasound medium in the container is pumped into the negative pressure cavity under the atmospheric pressure by reducing air pressure in the negative pressure cavity, when the air pressure inside and outside the negative pressure cavity is balanced, the liquid level in the negative pressure cavity is higher than that in the container, the top of the sound production surface of an ultrasound transducer is soaked in the medium, ultrasonic waves produced by the ultrasound transducer are conducted in the medium completely, meanwhile, the requirement for the liquid level in the container is reduced, and negative effects such as discomfort of patients due to high liquid level are avoided.

Description

technical field [0001] The invention belongs to the technical field of high-intensity focused ultrasound, and in particular relates to an ultrasonic medium liquid level control device, focused ultrasonic treatment equipment and a medium liquid level control method. Background technique [0002] High Intensity Focused Ultrasound (HIFU) technology can form high-intensity and continuous ultrasonic energy on the lesion by focusing ultrasonic waves, thereby producing transient high-temperature effects, cavitation effects, mechanical effects, and sonochemical effects, making cell membranes 1. The nuclear membrane ruptures, coagulates the protein, selectively causes coagulation necrosis of the lesion tissue, and makes the lesion lose the ability to proliferate, infiltrate and metastasize. As a new technology for the treatment of tumors and other diseases, high-intensity focused ultrasound therapy has been clinically recognized and is widely used in the treatment of various tumors a...
