Ultrasonic waveguide provided with cooling system

Abstract

The invention discloses an ultrasonic waveguide provided with a cooling system. The ultrasonic waveguide comprises an ultrasonic waveguide casing and an ultrasonic transducer, wherein openings are formed in the top and the bottom of the ultrasonic waveguide casing; the ultrasonic transducer is connected with the ultrasonic waveguide casing through the opening in the top of the ultrasonic waveguide casing; a heat exchanger is arranged on the outer wall of the ultrasonic waveguide casing; and a cooling medium inlet and a cooling medium outlet are formed in the heat exchanger. According to the ultrasonic waveguide provided with the cooling system, a waveguide cap is added at the top end of a small opening of a conventional ultrasonic waveguide structure, so that an accurate spacial position relation between an ultrasonic focal spot and a conductive film interface at a waveguide cap top part is guaranteed, and three-dimensional precise positioning is not required for calibration. Therefore, the use efficiency is greatly improved and the use cost is reduced; and the heat produced in a working process of the ultrasonic transducer is taken away through a flowing cooling medium, and the temperature can be regulated, so that overheat damage caused by long-time working of a device is avoided.

Description

technical field [0001] The invention relates to an ultrasonic waveguide, in particular to an ultrasonic waveguide with a cooling system. Background technique [0002] Use ultrasonic waves to act on organisms to achieve therapeutic effects on diseases. The basic principle is to transmit ultrasonic waves of specific frequency, power, direction and focal spot size through the ultrasonic transducer, and gather the ultrasonic energy in a specific area of ​​biological tissue through the ultrasonic conduction structure (ie, ultrasonic guide), thereby generating Biochemical action to achieve therapeutic goals. [0003] In this type of traditional ultrasonic conduction structure, the ultrasonic transducer is connected to the large mouth of a tapered cavity made of plastic material (that is, the ultrasonic conduction shell) and sealed. The small mouth of the conical cavity (referred to as "cone") is sealed with a conductive film, so that the entire cone is in a sealed state. The in...

AI Technical Summary

Problems solved by technology

There is no structure for cooling in the traditional method, so when the focusing transducer and the conductive structure work for a long time at high power, the local or overall temperature may exceed the limit of the device, resulting in overheating damage

[0007] 3. In the traditional ultrasonic conduction structure, the medium used for ultrasonic coupling and conduction will produce bubbles after a period of ultrasonic action, causing additional attenuation or shielding of ultrasonic conduction, thus affecting the effect and stability of the equipment.

The operator must be familiar with the relevant operation methods and precautions, the operation is difficult, the cost is high, and it is not conducive to the rapid training of the operator
