Ultrasonic probe and manufacturing mehtod thereof

Abstract

The invention discloses an ultrasonic probe, which includes: a probe cover; a rotatable passive shaft supported by the probe cover; a converter supported by the passive shaft, rotatable at one end of the passive shaft, and capable of converting electrical signals and ultrasonic waves into each other; It is characterized in that it also includes: a rotatable driving shaft supported on the probe cover, at a certain distance from the passive shaft in a predetermined direction and kept parallel; a driving motor supported on the probe cover and driving the driving shaft; and passing through the passive shaft. The shaft and drive shaft transmit rotation from the drive motor to the drive belt of the converter. The converter transmits and receives reflected ultrasonic waves through the probe cover in a predetermined direction. The ultrasonic probe with such a structure separates the rotation axis of the drive motor and the converter, so that the radius of the converter is independent of the radius of the drive motor, thereby reducing the rotation radius of the converter, thereby obtaining a smaller ultrasonic probe. There is no backlash when the rotation of the drive motor is converted into the rotational motion of the converter, thus preventing the accuracy of the ultrasonic probe from being damaged.

Description

technical field [0001] The present invention relates to an ultrasonic probe and a method for obtaining tomographic images and other pictorial images from internal organs of the human body using ultrasonic waves, and more particularly to an ultrasonic probe and a doctor in a hospital using it to obtain tomographic images for diagnosis X-ray radiographic images and other methods of illustrating images. Background technique [0002] In recent years, various ultrasound probes have been developed and used for probing internal organs of the human body to help doctors in hospitals diagnose the human body. Among these ultrasound probes, all the probes can be classified into two types of ultrasound probes, the first type of which is in contact with the human skin and moves to detect the solid internal organs of the human body such as the liver and pancreas from the outside of the human body; and the second type of which Ultrasound probes are inserted into h...

AI Technical Summary

Problems solved by technology

[0006] It is easier to understand from the above-mentioned fact that this type of conventional ultrasonic probe faces the problem that the transducer with a rather large radius and cross-sectional area makes the overall volume of the ultrasonic probe unit very bulky

In addition, the fact that the gears of the converter are in driving engagement with the gears of the electric motor by means of reduction gears necessarily creates another problem, namely that these gears are therefore kept in meshing relationship with each other, necessarily resulting in lost motion to the converter, whereby Destroys the precision of the ultrasound probe unit
