Description
Technical Field
The invention belongs to the technical field of medical treatment, and particularly relates to a mammary gland flattening device for mammary gland molybdenum target photography.
Background
The mammary gland molybdenum target X-ray photographic examination is a simple, convenient and reliable noninvasive examination method for diagnosing mammary gland diseases, and has high resolution and good repeatability, and the left image can be used for front-back comparison. The method is particularly suitable for examining breast lumps which are not touched by doctors, particularly for large breasts and fat breasts, has higher diagnosis specificity, has higher sensitivity and specificity for early breast cancer which is only expressed by a little tiny calcium, and has important significance for early diagnosis and identification of the breast cancer. For the breast X-ray examination, the node can be detected, so that the node is required to be punctured for further clear diagnosis, partial tissues of the tumor are taken out for biopsy, and then the benign and malignant tumors are judged, so that a basis is provided for subsequent guidance.
In the existing mammary gland X-ray examination, a patient's breast is generally required to be placed on an examination table, then a radiation source irradiates downwards from the top end, the internal structure of the breast is photographed into a plane, if calcification, fibrosis and the like exist in the plane, a high-density shadow appears on the photographed plane, the calcification in breast cancer often appears in a starburst shape or a radial shape, the breast is photographed into a plane image during photographing, so that the condition of tissue structures in the plane can be photographed, but lesions perpendicular to the plane can be overlapped, and therefore, the breast is usually required to be photographed after being clamped at an angle (such as 15 degrees from left to right) so as to prevent the overlapping of the tumor in the vertical plane from causing omission. After moving shooting, positioning is carried out on a shot picture, and a puncture point which is closer to the skin is selected as a point for entering a puncture needle, but the X-ray picture is positioned at present, but the X-ray picture is not positioned on the surface of a mammary gland, and the situation that the morphology of the X-ray picture is changed when the mammary gland changes position and the like is inconsistent with the positioning point during shooting occurs, so that puncture failure is caused.
At present, for the mammary gland with smaller volume or softer mammary gland, the mammary gland is difficult to be placed on a shooting plate, the mammary gland cannot be well exposed and laid on the shooting plate smoothly, and for the softer mammary gland, if the gland cannot be laid on the shooting plate, the gland can have overlapping shadows on an image slice, and the specific position of the mammary gland tumor cannot be well positioned; for patients with smaller breasts, the breasts cannot be fully exposed to the shooting plate, so that the imaging effect is poor; for patients with crater nipple, the crater nipple causes the photographed piece nipple to be not outside the arc outline of the mammary gland, and the overlapping shadow can not well observe whether the nipple and surrounding tissues have tumor. At present, when shooting a film, the breast is downwards pressed from the chest wall by hands, so that the breast is pressed on a shooting plate, the hand is continuously moved to a position far away from the breast, the part of the breast, which is positioned on the shooting plate, is spread, folding is avoided, the breast is required to be pulled to be placed on a flat plate as far as possible by a patient with small nipple retraction or smaller breast, and the nipple is positioned at a tangential position, but spreading and fixing are carried out by a manipulation, the retraction of the breast gland influences shooting when the shooting position is changed, the spreading of the manipulation is unfavorable for protecting privacy of the patient, unnecessary misunderstanding is easily caused, the spreading effect of the manipulation is poor, the mammary is only spread once by the manipulation in the process of downwards moving a compression plate, and the hand cannot be inserted for spreading the manipulation when the space between the compression plate and a lower baffle is limited.
