Three dimensional ultrasound probe head of bladder capacity measuring device

Abstract

The invention provides a three-dimensioned ultrasonic probe of bladder capacity testers and pertains to the technical field of medical instruments. The three-dimensioned ultrasonic probe of bladder capacity testers comprises a sound transparent film enclosure with a handle, the sound transparent film enclosure is provided with an upper arranged stepper motor which is coordinated and connected with the ultrasonic crystal and is arranged horizontally in the cavity, the handle is provided with a lower arranged stepper motor and a wire connector in the lumen; the upper arranged stepper motor, thelower arranged stepper motor and the ultrasonic crystal are connected with the wire connector by leads; an outer rotor stepper motor is adopted as the upper arranged stepper motor, the outer rotor stepper motor comprises a rotor component and a stator component with a stator shaft, the ultrasonic crystal is connected with the case shell of rotor of the rotor component, the upper arranged stepper motor is arranged on the front bracket by the stator shaft thereof, a front seat fixed with the sound transparent enclosure is arranged at the lower part of the front bracket, the lower arranged stepper motor is arranged vertically and is connected with the lower part of the front seat, and the output shaft of the lower arranged stepper motor is connected with the front bracket. The ultrasonic probe is characterized by simple structure, no noise, long service life and precision in multi-section imaging.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a three-dimensional ultrasonic probe of a bladder capacity measuring instrument. Background technique [0002] At present, domestic studies on the pathological and clinical aspects of bladder capacity measuring instruments have a certain degree of depth, and the host system of bladder capacity measuring instruments is also tending to be perfected. However, there has not been a three-dimensional ultrasonic probe necessary for bladder capacity measuring instruments with excellent performance, advanced structure and reliability. . [0003] At present, the only manufacturer in the world that produces and sells bladder volume measuring instruments is the American Ultrasonic Diagnostics Company. Its probe adopts its patented V-MODE three-rotation probe, and the main structure of the V-MODE three-rotation probe is an upper-mounted stepping motor. The swing scanning of the u...

Problems solved by technology

Therefore, the V-MODE three-rotation probe must have the following defects: 1. The structure is complex; 2. The meshing noise of the multi-stage reduction gear; The gap between the stator and the rotor is small (<0.03mm), and the oil is easily deteriorated in the gap due to magnetic flux and dynamic friction, so the service life of the motor is short; Very large, affecting the service life of the probe; 5. When the host is used, only 12 slices from the bladder can be supervised, and only six imaging bladder images of different slices can be generated
