AI Technical Summary

Technical Problem

In existing animal ultrasound irradiation experiments, the adjustment of the distance between the ultrasound probe and the surface of the test object can lead to excessive coupling agent, which can easily submerge the experimental animal and cause suffocation. In addition, the focal point may not be accurately aligned with the lesion, and the energy cannot be effectively focused, which may cause secondary damage.

Method used

Design an ultrasonic irradiation device with the ultrasonic transmitter located below the test object. Adjust the position of the test object by adjusting the mechanism so that the lesion area coincides with the focal point. The boundary of the treatment area restricts the flow of the coupling agent to ensure that the coupling agent accumulates and contacts the test object.

Benefits of technology

This method enables the directional focusing of ultrasound energy onto the lesion tissue, enhancing therapeutic gain, avoiding energy dispersion and damage to non-target tissues caused by focus deviation, and improving experimental safety and reliability.

Abstract

The application discloses an ultrasonic irradiation device, and relates to the technical field of ultrasonic irradiation equipment, which comprises an irradiation mechanism, an adjusting mechanism and a treatment area, wherein the ultrasonic emission end of the irradiation mechanism is located below a to-be-tested object; the adjusting mechanism is used for bearing the to-be-tested object and can adjust the position of the to-be-tested object according to the lesion depth inside the to-be-tested object, so that the lesion area of the to-be-tested object is coincident with the focal point of the irradiation mechanism; and the treatment area is used for containing the to-be-tested object and a coupling agent arranged between the ultrasonic emission end and the to-be-tested object; the treatment area has a boundary, and the boundary is used for limiting the flow of the coupling agent, so that the coupling agent accumulates and contacts the to-be-tested object. The application improves the treatment gain of stimulation and improves the safety and reliability of treatment.
