Driving control device of intravascular ultrasonic probe and intravascular ultrasonic imaging system

Abstract

The invention discloses a driving control device of an intravascular ultrasonic probe and an intravascular ultrasonic imaging system. The driving control device of the intravascular ultrasonic probe comprises a driving mechanism, a first transmission mechanism and a second transmission mechanism, wherein the first transmission mechanism drives the probe to do withdrawing motion; the second transmission mechanism drives the probe to do rotating motion; the first transmission mechanism and the second transmission mechanism are respectively in transmission connection with an output portion of thedriving mechanism; and when the driving mechanism works, the first transmission mechanism and the second transmission mechanism can simultaneously output power. The driving control device has the advantages that one driving mechanism is used for driving the two transmission mechanisms, thus, when the driving mechanism outputs the power, the first transmission mechanism and the second transmissionmechanism are in a power output state; the same power source is used, so that good synchronism of the output of the first transmission mechanism and the output of the second transmission mechanism can be ensured; a complicated control strategy of the driving mechanism is not needed; structure simplification and control strategy simplification can be realized; production and assembly are facilitated; and the cost is easy to control.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and more specifically, to a drive control device for an intravascular ultrasonic probe. In addition, the present invention also relates to an intravascular ultrasonic imaging system comprising the above-mentioned drive control device for the intravascular ultrasonic probe. Background technique [0002] Intravascular ultrasound is an imaging technique in which an ultrasound transducer is inserted into the cardiovascular cavity through a catheter to obtain the cross-sectional morphology or blood flow pattern of the cardiovascular system using ultrasound, which can be used to examine the condition of the vessel wall. During the imaging process, the ultrasonic transducer performs rotational movement and retraction movement in the blood vessel to realize image formation. [0003] The existing intravascular ultrasound driver mainly includes a rotating motor, a retracting motor, and a sliding...

Problems solved by technology

[0005] However, the synchronization effect between the motors is poor, and the slight error between the two will cause the dislocation of the synthesis of the two slices during image synthesis, resulting in the problem of poor synthesis of imaging. If complex control logic and control structure Controlling the synchronization of motors is not only costly, but also difficult to control and relatively difficult to assemble

[0006] To sum up, how to solve the problem of poor composite effect of ring scan imaging and retraction imaging is a technical problem that needs to be solved at present
