Abstract

The invention provides an ultrasonic scanning probe, which comprises a shell (3), a transducer (13), a transducer support (14), a probe body (8), a half bevel gear (11), a shaft bevel gear (26), a spur gear (20), a dual internal gear (17), a planetary gear train, a motor gear (19) and a drive motor (9). In the ultrasonic scanning probe , the defects of forceless inducer swing and ununiform scanning process can be solved, required high torque in a limited space can be obtained, the weight of the probe can be reduced, meanwhile, in terms of a sealing scheme, the ultrasonic scanning probe is strictly sealed, and therefore can meet waterproof and dustproof requirements, the shell is made of soft rubber and hard rubber by rubber-coating injection molding, an upper shell and a lower shells of the probe are solidified by adopting epoxy glue, a glue groove for containing the glue and a glue line are designed between the upper and the lower shells of the probe, consequently, the firmness and reliability of the structure can be guaranteed, and tightness and safety can be sufficiently ensured as well.

Description

technical field [0001] The invention relates to the technical field of medical ultrasound, in particular to an ultrasonic scanning probe. Background technique [0002] The existing ultrasonic scanning probe used for 4D imaging fixes the transducer on the transducer frame, the transducer frame and the transducer shaft are fixed, and the transducer frame is driven to rotate by mechanical transmission while driving the transducer to swing to realize ultrasonic scanning. For the 4D imaging of the probe, the mechanical transmission generally uses a direct motor to drive the swing of the transducer, or uses a bevel gear for one-stage deceleration, or uses a simple two-stage gear or belt drive to drive the transducer to shake, but in mechanical transmission In the process, due to the small transmission ratio, the swing torque of the transducer part is small, and it is difficult to realize the high-speed swing of the transducer. Contents of the invention [0003] Aiming at the pr...
