Sourd transparent intestinal canal pushing apparatus for high-strength focusing supersonic wave treatment

Abstract

The present invention relates to an acoustically transparent intestinal tract pusher applied in high-intensity focused ultrasound treatment, which comprises an ultrasound treatment head and a membrane bag filled with an ultrasound-conducting medium; wherein, the ultrasound treatment head emits ultrasound, which passes through the membrane bag to treat the focus of a patient; the membrane bag can be placed at a position on the skin of the patient, which corresponds to the focus; the membrane bag is communicated with a medium-circulating unit; and the medium-circulating unit can circulate the ultrasound-conducting medium in the membrane bag. The pusher can form a reliable acoustically transparent channel between an ultrasound source and the diseased organ of the human body, enhance energy deposition at a target region and bring away the heat generated in the process of treatment in order to prolong the irradiation time of ultrasound.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an ultrasonic therapy device, in particular to a sound-transparent intestinal pushing device for high-intensity focused ultrasonic therapy. Background technique [0002] High-intensity focused ultrasound therapy technology can form high-intensity and continuous ultrasonic energy on the lesion by focusing the ultrasound, thereby producing transient high-temperature effects, cavitation effects, mechanical effects and sonochemical effects, causing cell membranes and nuclear membranes to rupture and protein coagulation , to selectively cause coagulation necrosis of the lesion tissue, so that the lesion loses the ability of proliferation, invasion and metastasis. 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 and non-tumor diseases. ...

Problems solved by technology

[0005] The Chinese patent with the publication number CN 2503915Y discloses a conductive medium accommodation structure for a high-energy focused ultrasonic treatment device. The conductive medium containing structure used to isolate or squeeze the organs around the target area is only a hemispherical film, and the conductive medium is almost completely sealed in the hemispherical film structure, so the heat generated by the focused ultrasound energy cannot be timely If it is taken away, the temperature of the medium is very high, which is easy to cause damage to the film interface, and the ultrasonic transducer is also easy to break; at the same time, the film made of latex, silicone rubber or natural rubber is filled with the medium and squeezed in contact with the human body. When the target area needs to be adjusted, the ultrasonic treatment head can only be moved, so that the pressure in the containing medium structure changes, and the effect of forming a sound-transmitting channel when treating lesions is unreliable
