Description

Mammary gland magnetic resonance imaging and intervention integrated device and box body thereof

Technical Field

The utility model relates to the technical field of medical equipment, in particular to mammary gland magnetic resonance imaging and intervention integrated device and box body thereof.

Background

Breast tumors are the most common tumors in women, with a proportion of up to 31%. In recent years, magnetic resonance imaging techniques have been employed in the early detection of breast cancer in research to reduce the mortality of breast cancer.

The treatment effect of the breast cancer depends on the disease stage of the tumor, and the improvement of the early diagnosis rate of the breast cancer is the key for improving the cure rate. According to SEER database, when the breast cancer is still in the stage 0 to II, the cure rate can be as high as 93%, once the breast cancer reaches the stage III, the cure rate is rapidly reduced to 72%, and when the breast cancer reaches the stage IV, the cure rate is only 22%. Early detection of breast cancer, screening for breast cancer, biopsy and treatment are therefore important.

The most clinically superior breast imaging detection method at present is the magnetic resonance imaging method. The magnetic resonance imaging method has the natural advantages of no radiation, sensitivity to soft tissue imaging, capability of generating a scanning image with high resolution and high signal-to-noise ratio, capability of providing information on tissue perfusion, molecular level change and tissue metabolism, and is the imaging means with the highest breast cancer diagnosis rate at present.

The conventional method for treating breast cancer is mainly surgical resection and is assisted by chemotherapy and radiotherapy, but the treatment mode causes huge trauma to the body and mind of women. Sometimes, the therapeutic effect is not good or even counterproductive to many patients due to individual variability. With the increasing requirements of people on breast cancer treatment and postoperative life quality, treatment methods with small damage and fast recovery are more and more popular with people, and most of traditional surgical treatment is developing from invasive surgery treatment to non-invasive or minimally invasive treatment.

With the development of medical imaging technology, the clinical requirement for image-guided intraoperative minimally invasive treatment methods for mammary glands is increasing. The MRI minimally invasive treatment in the operation is the most advanced image-guided minimally invasive breast cancer treatment method in the world at present, under the guidance of magnetic resonance images, operations such as biopsy and ablation can be rapidly and accurately carried out on a breast lesion area, and the method has the characteristics of accurate positioning, small damage, good treatment effect and the like, and the tumor treatment effect can be evaluated in real time in the operation, which is incomparable with other conventional operations.

The magnetic resonance imaging device comprises a radio frequency transmitting coil and a receiving radio frequency coil which are respectively used for generating a pulse gradient magnetic field and receiving nuclear magnetic resonance signals generated by atomic nuclei, the radio frequency receiving can also be realized by the radio frequency transmitting coil, or the radio frequency receiving coil can also be independently arranged, and in the magnetic resonance imaging system, the uniformity of the magnetic field generated by the radio frequency transmitting coil and the signal to noise ratio of the signals received by the receiving coil are key factors influencing the image quality. Furthermore, the closer the radio frequency coil is to the imaging subject, the higher the strength of the received magnetic resonance signal. Generally, the higher the magnetic field homogeneity and the higher the signal-to-noise ratio, the higher the image quality.

When the magnetic resonance imaging device is adopted, the mammary gland of a patient needs to be fixed in an imaging area, and the imaging area is too large or too small for patients with different mammary glands in size and shape, so that the applicability of the magnetic resonance imaging device is not high, and when the mammary gland of the patient is not matched with the imaging area, the detection result is influenced. Moreover, most of the existing magnetic resonance breast imaging devices and breast interventional devices are mutually independent, and the breast imaging devices, namely breast coils, can not be well attached to a breast fixing device, so that the imaging quality of breast magnetic resonance scanning can not be ensured during breast interventional operations.

In view of this, how to provide a device, which can not only complete breast magnetic resonance imaging, but also provide fixing and positioning functions for breast intervention, has higher applicability and accuracy, is a technical problem to be solved by those skilled in the art.
