Description
Technical Field
The invention relates to the technical field of mammary gland detection equipment, in particular to an auxiliary positioning device special for mammary gland molybdenum target examination, and further relates to a positioning puncture suite matched with the auxiliary positioning device special for mammary gland molybdenum target examination.
Background
The mammary gland molybdenum target is called mammary gland molybdenum target X-ray radiographic examination, is a commonly used examination method for clinically detecting mammary gland diseases, is a simple, reliable and noninvasive examination method for diagnosing the mammary gland diseases, has the advantages of high resolution, good repeatability, capability of comparing left and right images and the like, and is particularly suitable for examining mammary gland masses which can not be touched by doctors (for example, mammary gland masses can not be touched by large-breast and fat-type breast doctors); for early-stage breast cancer which takes a little micro-calcification as the only expression, the breast molybdenum target has higher sensitivity and specificity, is an important basis for early diagnosis and identification of the breast cancer, and also provides an instructive basis for subsequent treatment.
Currently, a breast molybdenum target generally requires a patient to stick a breast on a breast molybdenum target machine, then the breast is compressed and flattened through a pair of clamping plates, a radioactive source irradiates downwards from the top end to shoot the internal structure of the breast into a plane, and the shot image is observed, wherein if calcification, fibrosis and other conditions exist in the breast, a high-density image (such as a star-shaped or radial shape) appears in the shot plane image. Because the breast is photographed as a planar image, the tissue structure in the plane can be photographed, but the lesions perpendicular to the plane may overlap, so the breast is usually clamped and photographed after being changed in angle (for example, moved 15 degrees to the left or right), and the missed puncture caused by the overlapping of the tumors in the vertical plane of the breast is prevented.
At present, the common mammary gland molybdenum target is only positioned on an X-ray picture but not positioned on the surface of a mammary gland body (namely a breast), and when the position of the mammary gland is changed, the shape of the mammary gland molybdenum target is changed and is inconsistent with the positioning point during shooting, so that subsequent puncture failure is easily caused. In addition, some patients' mammary glands are small or soft, and are difficult to place on the shooting clamping plate, the mammary glands cannot be well exposed and laid on the shooting plate smoothly, only one end of the mammary gland can be pulled, and the mammary gland can be flattened by hands, but when the shooting position is changed, the mammary gland retraction can greatly influence shooting.
