New type Doppler probe

Abstract

The invention provides a new type Doppler probe. The new type Doppler probe comprises a sleeve and a shell body, a piezoelectrics is arranged in the sleeve, the wave vibrating generating face of the piezoelectrics is attached to the shell bottom face of the shell body, a film body is clamped between the wave vibrating generating face of the piezoelectrics and the shell bottom face, threaded sections are correspondingly arranged on the peripheral wall of the sleeve and the inner wall of the shell body; and an annular protruding block is arranged on the outer wall of the rear end of the sleeve in the screw-in direction, and an annular groove is formed in the inner wall of the front end of the shell body in the screw-in direction. After the annular protruding block crosses the groove wall of the annular groove through applied force, the annular protruding block is located in a groove cavity of the annular groove to limit the position of the axial direction of the shell body; while dismounting, excessive external force is applied to enable the annular groove in the shell body to be deformed in the radial direction, so that the annular protruding block crosses the groove wall of the annular groove, continuous convoluting is conducted to finish dismounting, the sleeve and the shell body are matched firmly and reliably, the structure is simple, and the new type Doppler probe can be mounted and dismounted quickly by an operator.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a novel Doppler probe. Background technique [0002] In the treatment of hemorrhoids, the Doppler probe needs to detect the hemorrhoidal artery and ligate the hemorrhoidal artery. After the ligation is completed, the hemorrhoid body is sutured and suspended. The transducer in the Doppler probe is fixed by glue and sealed to achieve a sealing effect. Once a small problem occurs in the probe, it cannot be disassembled to analyze the fault, and the probe cannot be inspected and repaired. Generally, the only option is to choose Replacing the entire probe part not only increases the cost, but also brings a lot of trouble to the monitoring work. Contents of the invention [0003] The purpose of the present invention is to provide a new type of Doppler probe, which is convenient for disassembly and assembly, and reduces the cost of replacement and maintenance. [0004] In order to a...
