Ultrasonic probe for breast diagnosis

Abstract

The invention relates to an ultrasonic probe for breast diagnosis. The ultrasonic probe comprises a probe body, below which an inwardly-concave hemisphere matching a breast is arranged. A negative-pressure adsorption device used for evacuating the interior of the hemisphere is arranged above the probe body. A track equipped with multiple rows of piezoelectric crystallites is arranged above the hemisphere and driven by a motor to annularly rotate along the hemisphere. The ultrasonic probe for breast diagnosis has following beneficial effects: during application, the hemisphere abuts against the breast and the negative-pressure adsorption device is utilized for evacuating the interior of the hemisphere such that surface skin of breast tissue can be closely attached to the surface of the hemisphere, thereby achieving good ultrasonic conduction; the piezoelectric crystallites are driven by the motor and the track to annularly rotate along the hemisphere such that a complete and clear ultrasonic image for breast tissue can be displayed; and the ultrasonic probe helps to increase lesion detection rate and checking efficiency and is easily and conveniently operated and prompted.

Description

technical field [0001] The invention relates to an ultrasonic probe, in particular to an ultrasonic probe for breast diagnosis. Background technique [0002] As an important examination method for breast cancer screening, breast ultrasound (BUS) has always attracted people's attention due to its economical, simple, non-invasive, clear and repeatable characteristics, as well as its high sensitivity and specificity for breast diseases. BUS can not only effectively identify breast cystic / solid lesions, but also is an important auxiliary examination method for routine mammography (MG), which effectively makes up for the disadvantage of MG's reduced sensitivity to dense breast tissue. The screening data of 9082 cases of breast cancer in Japan reported by Uchida et al. showed that: BUS can further detect 15% of breast cancers missed by MG. Therefore, the application of ultrasound in routine female breast physical examination and breast cancer screening can detect most breast dise...

Problems solved by technology

[0003] However, due to the lack of unified operating standards, the current traditional ultrasonic instrument with hand-held probe requires high operator experience, is easily affected by subjective factors, has relatively insufficient spatial resolution, and stores a small amount of information, which limits its use on a large scale. Application in breast examination and screening

[0004] In recent years, the automated breast volume scanner (ABVS) represented by Siemens Acuson S2000 equipment, as a new imaging technology, provides a more standardized, standard and sensitive breast ultrasound examination mode for the diagnosis of clinical breast diseases. The value of early diagnosis of diseases has been recognized by the industry, but due to the limitation of the probe design and the limited scanning area, multiple scans are required in large-scale detection, which increases the scanning time and has limited efficiency; the overall equipment is expensive and the maintenance cost is high. Factors hinder its promotion in large-scale breast disease screening

Considering the basic national conditions of China with a large population, the allocation of medical resources is relatively insufficient, and there is a certain gap between urban and rural areas, so the coverage and efficiency of large-scale breast screening for Chinese women cannot be fully guaranteed
