Ultrasonic probe

Abstract

The invention provides an ultrasonic probe. According to the ultrasonic probe, an elastic shaft of the ultrasonic probe comprises a main shaft section and an inclination angle shaft section, and the main shaft section and the inclination angle shaft section are connected into a whole; the main shaft section and the inclination angle shaft section have different minimum bending radiuses, and particularly, the minimum bending radius of the inclination angle shaft section is smaller than the minimum bending radius of the main shaft section, which can be realized by setting the main shaft sectionand the inclination angle shaft section to be of different structures, to be made of different materials or to be manufactured by using different processes, etc; the minimum bending radius of the mainshaft section is large, so high transmission precision can be guaranteed during long-distance rotary transmission, and the bending requirement of the main shaft section can be met; due to the fact that the rotation transmission of the whole elastic shaft is mainly based on the main shaft section, although the minimum bending radius of the inclination angle shaft section is small, the transmissionprecision of the whole elastic shaft cannot be greatly affected; and on the contrary, due to the fact that the minimum bending radius of the inclination angle shaft section is small, the requirementfor a small bending radius can be met, and the bending requirement of the inclination angle pipe can be better met.

Description

technical field [0001] The present application relates to a medical device, in particular to an elastic shaft structure of an ultrasonic probe. Background technique [0002] The ultrasonic probe is an important part of ultrasonic equipment (such as ultrasonic diagnostic imaging equipment). Its working principle is to use the piezoelectric effect to convert the excitation electrical pulse signal of the ultrasonic machine into an ultrasonic signal into the patient's body, and then transmit the ultrasonic echo signal reflected by the tissue Converted into electrical signals, so as to realize the detection of tissues. [0003] Among them, an ultrasonic probe can be inserted into the cavity of a human body or an animal, such as a transesophageal ultrasonic probe, etc. This type of ultrasonic probe mainly includes a handle assembly, an insertion tube assembly and an acoustic head assembly. The insertion tube assembly is connected between the handle assembly and the acoustic head ...

AI Technical Summary

Problems solved by technology

In order to facilitate the diagnostic operation, in the process of clinical operation, it is required that the end of the insertion tube assembly connected to the acoustic head assembly can be bent to a large extent, so that the acoustic head assembly can change its position in a larger area, but excessive bending Capacities will result in reduced efficiency of the insertion tube assembly for the transmission of rotational motion, therefore, the use of a suitable insertion tube assembly is very important for this type of ultrasound probe
