As shown in fig. 1, it includes an ultrasound transmission device 100 and a coupling fluid seal assembly 200 for focusing ultrasound. The coupling liquid sealing component 200 for focusing ultrasonic comprises a bag body 1 with two open ends and a waterproof adhesive ring 2. The ultrasonic transmitter 100 is disposed in the pouch body 1. The first connection face 201 of the waterproof adhesive ring 2 is intended to be stuck on the skin S of the patient; the second connecting surface 202 of the waterproof adhesive ring 2 is adhered to the first end 101 of the bag body 1, and the second end 102 of the bag body 1 is tightly connected to the housing 3 of the ultrasonic transmitter 100. So that the bag body 1, the shell 3 of the ultrasonic transmitter 100 and the skin enclose a sealed area m capable of containing the coupling liquid.
Compared with the wet coupling of the human body completely immersed in water, the focusing ultrasonic therapy system adopts the bag body 1 to accumulate the coupling liquid to carry out the wet coupling with the human body, reserves the advantages of using water as a single coupling medium, thereby having less attenuation, thorough coupling and good effect, and overcomes the defects of easy water leakage, complex and heavy structure of equipment.

Therefore, the operation is more convenient and time-saving, and the treatment effect is better.
Therefore, the focused ultrasound treatment system of the embodiment occupies a small space, has a wide application range, requires a lot of auxiliary equipment, consumes a lot of coupling liquid, and reduces the energy consumption by about 90%. The sound transmission capacity and the coupling effect are completely the same.
Compared with the traditional dry coupling, the bag body 1 of the embodiment is combined with a human body in an open mode, the coupling liquid is filled in the bag body 1, the coupling liquid is purely used as a coupling medium between the ultrasonic emission surface of the ultrasonic emission device 100 and the skin, the human skin and the coupling liquid are not separated by sealing film media such as silica gel, and redundant ultrasonic reflection and attenuation surfaces existing in the traditional dry coupling are reduced, so that the attenuation is reduced, the coupling is thorough, the coupling state is more stable, and the ultrasonic effect is better.
