Abstract

The invention discloses an ultrasonic focusing transducer. The ultrasonic focusing transducer comprises a shell, a piezoelectric ceramic wafer, a fixed sealing part and a support, wherein the piezoelectric ceramic wafer, the fixed sealing part and the support are contained in the shell. The piezoelectric ceramic wafer is of a spherical segment shape and is provided with a spherical-segment-shaped through hole, the spherical-segment-shaped through hole is provided with a first side opening and a second side opening, the hole diameter of the first side opening is smaller than that of the second side opening, one end of the second side opening of the piezoelectric ceramic wafer abuts against one end of the shell, and one end of the first side opening of the piezoelectric ceramic wafer faces the other end of the shell. The fixed sealing part is annular, is installed on the inner surface of the shell, abuts against the piezoelectric ceramic wafer and is used for being connected with the support in a sealing mode. The support is provided with a clamping part, and the clamping part is used for extruding and clamping the periphery of the first side opening of the piezoelectric ceramic wafer. The fixed sealing part, the support and the piezoelectric ceramic wafer define a closed air cavity. The invention further discloses an ultrasonic focusing treatment head. The sealing performance of the air cavity of the ultrasonic focusing transducer is good.

Description

technical field [0001] The invention relates to the technical field of ultrasonic medical instruments, in particular to an ultrasonic focusing transducer and an ultrasonic focusing treatment head. Background technique [0002] Ultrasound therapy has the advantages of non-invasive, efficient, and controllable, and the tumor can be heated to an effective treatment temperature through ultrasonic focusing technology. Ultrasonic focusing transducers can be used in gynecological diseases, liver cancer, breast cancer, pancreatic cancer, kidney cancer, soft tissue tumors, etc. [0003] The ultrasonic focusing treatment head includes an ultrasonic focusing transducer and a probe accommodated in the ultrasonic focusing transducer, generally speaking, the probe is a heart probe. The ultrasonic focusing transducer converts high-frequency electric energy into ultrasonic waves of the same frequency through piezoelectric ceramic chips, and then realizes the therapeutic function through ul...
