Problems solved by technology

This will lead to frequent replacement of ultrasound probes by doctors, increase the workload of doctors, and increase the cost of medical equipment, and there are too many types of ultrasound probes, which is inconvenient to manage
For example, a variety of ultrasound probes take up a lot of storage space, and the ultrasound machine needs to have more ultrasound probe interfaces that are convenient for doctors to replace, and places for temporary placement of ultrasound probes

Abstract

An embodiment of the invention discloses an ultrasonic probe and an ultrasonic testing method. The ultrasonic probe comprises a casing, a probe connection wire, a probe transducer, a lens converter and a matching layer, wherein the lens converter comprises a rectangular lens and a lens shape conversion control part and is arranged at the other end of the casing and connected with the matching layer, the lens shape conversion control part is used for changing the shape of the rectangular lens to be matched with a pointed part, and at least one of a linear array probe lens, an arc array probe lens and a phased array probe lens is realized. According to the ultrasonic probe and the ultrasonic testing method, ultrasonic testing of different depth to the skin and different parts of a human body is realized.

Description

technical field [0001] Embodiments of the present invention relate to the field of medical devices, and in particular, to an ultrasonic probe and an ultrasonic detection method. Background technique [0002] The ultrasound system radiates the ultrasound signal generated from the transducer of the ultrasound probe to the inside of the target object, and receives information of the echo signal reflected from the inside of the target object, thereby acquiring an image of the inside of the target object. Specifically, ultrasound systems are used in medicine to look inside the human body, detect foreign objects, and assess damage. [0003] Ultrasound systems have higher stability than diagnostic equipment using X-rays, display images in real time, and are safe because there is no exposure to radioactive substances, so they are widely used together with other medical image diagnostic equipment. [0004] In the prior art, since each organ of the body has different distances from t...
