Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a mammary gland magnetic resonance imaging and intervention integrated device and a 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.

This first splint 2 and second splint 3 are used for enclosing into the holding chamber, and the two forms preceding lateral wall and the back lateral wall in holding chamber promptly, and this mammary gland image device during operation, the holding chamber is used for holding patient's mammary gland to carry out mammary gland nuclear magnetic resonance imaging or mammary gland intervention operation.
Meanwhile, as shown in fig. 4, the case 1 further includes an adjusting assembly 4 for adjusting a distance between the first clamping plate 2 and the second clamping plate 3.
In this embodiment, because first splint 2 and second splint 3 form the lateral wall in holding chamber, when changing the distance between the two through adjusting part 4, can change the size in holding chamber to make this holding chamber can adapt to the different patient's of size shape breast, and wide to the coverage of mammary gland, thereby improve this mammary gland imaging device's suitability. More importantly, the breast of the patient can be fixed by the first splint 2 and the second splint 3, so that the breast can be prevented from moving during the magnetic resonance imaging or interventional operation to interfere with the image quality and the interventional operation. Meanwhile, when the accommodating cavity is matched with the mammary gland of a patient, the accuracy of a detection result can be improved.
Specifically, this adjusting part 4 includes matched with lead screw and slider, wherein, the lead screw extends along the distribution direction of first splint 2 and second splint 3, in this embodiment, the lead screw extends along the fore-and-aft direction of box body 1, and when the lead screw rotated, the axial linear motion of lead screw can be followed to the slider, and simultaneously, first splint 2 and/or second splint 3 link to each other with the slider to when making the lead screw rotate, drive first splint 2 and/or second splint 3 and remove, and then change the distance between first splint 2 and the second splint 3.
Meanwhile, the second splint 3 is provided with a fixing structure for fixing instruments required during the interventional operation and enabling the instruments to extend into the accommodating cavity so as to perform the interventional operation.
In particular, as shown in fig. 3, the second splint 3 is provided with a plurality of fixation holes 31, and in particular, 4 rows and 7 columns of grid holes 1cm by 1cm may be provided for providing positioning and fixation for the breast interventional instrument.

In addition, the present invention further provides a breast mri and intervention integrated device, as shown in fig. 1 and fig. 6, the breast mri and intervention integrated device includes a box 1 and an imaging coil 5, wherein the box 1 is the box 1 described in any of the above embodiments. Since the box body 1 has the above technical effects, the integrated device for magnetic resonance imaging and intervention of mammary gland comprising the box body 1 also has corresponding technical effects, which are not described herein again.
Meanwhile, the second splint 3 of the integrated breast mri and interventional device is provided with a plurality of fixing holes 31, and the fixing holes 31 are used for fixing interventional instruments during interventional operation.
Therefore, the breast magnetic resonance imaging and intervention integrated device can realize nuclear magnetic resonance, when the breast magnetic resonance imaging and intervention integrated device works, the imaging coil is used for generating a radio frequency magnetic field, magnetic moments in a human body are excited to generate a nuclear magnetic resonance signal, and after the nuclear magnetic resonance signal is subjected to coil acquisition and integrated processing by an electronic circuit and software, data and images of a nuclear magnetic resonance imaging system are finally obtained. Wherein the imaging coil is a receiving coil.
As described in the background art, in order to improve the image quality, the method can be implemented by improving the signal-to-noise ratio of the received signal and improving the uniformity of the magnetic field generated by the transmitting coil, wherein there are two methods for improving the signal-to-noise ratio, the most common is the phased array coil technology, a plurality of independent small coils cover the region together, and because only when the adjacent coils are the same coil, the phased array coil is used, which can hardly ensure the uniformity of the magnetic field generated by the coil, especially for screening and diagnosing the breast diseases on the human body, the design requirement of the magnetic resonance radio frequency receiving coil for breast scanning requires higher signal-to-noise ratio, larger scanning range and more uniform signal distribution, so as to improve the screening and diagnosis rate of the breast diseases.
Specifically, as shown in fig. 6 and 7, the imaging coils 5 are disposed at the bottom and the side of the accommodating cavity, so that signals of the bottom and the side can be received, and accuracy is improved.
