Problems solved by technology

[0002] At present, the probes used in domestic ultrasonic equipment are all single-drive asynchronous scanning probes, which are limited by the load capacity of the single drive type, the scanning frequency of the probe is low, and because the position of the probe cannot be detected and synchronized, this type of probe is reciprocating. Only one frame of data can be taken during scanning
The frame rate of the video obtained by the ultrasound equipment is low and the image is not stable

Abstract

The invention discloses a double-drive type synchronous scanning ultrasonic probe, which comprises a probe shell, a second connecting shield, a main body and a printed circuit board, wherein in the second connecting shield, a driving mechanism is arranged at the lower end of the main body; the driving mechanism comprises two drivers which are arranged at the lower end of the main body and are connected to the printed circuit board, a linear guide way, a sliding block which moves along the linear guide way and is used for fixing a transducer base and a toothed belt seat which is fixed to the sliding block; a gear is fixedly arranged on a driving shaft of each driver; a toothed belt, which is meshed with the gears, is embedded in one side face of the toothed belt seat; and U-shaped photoelectric switches, which are connected to the printed circuit board, are fixed to two sides of the linear guide way. According to the ultrasonic probe provided by the invention, the scanning frequency of the ultrasonic probe can be increased, video frame frequency of an ultrasonic instrument can be increased, and linearity and stability of mechanical scanning can be improved, and the effective travel of an ultrasonic transducer can reach 22mm or above.

Description

technical field [0001] The invention relates to a scanning probe, in particular to a dual-drive synchronous scanning ultrasonic probe. Background technique [0002] At present, the probes used in domestic ultrasonic equipment are all single-drive asynchronous scanning probes, which are limited by the load capacity of the single drive type, the scanning frequency of the probe is low, and because the position of the probe cannot be detected and synchronized, this type of probe is reciprocating. Only one frame of data can be taken during scanning. As a result, the video frame rate obtained by the ultrasound equipment is low and the image is not stable. In order to obtain more stable ultrasound data, it is urgent to improve the existing ultrasound scanning probe. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an ultrasonic scanning probe with high load capacity and position detection and sy...
