AI Technical Summary
The existing mammography breast fixation device has a single clamping force applied to the breast, resulting in misdiagnosis or misdiagnosis of some breast marginal lesions. At the same time, the patient may shrink back due to pain or have too small breasts, resulting in some breasts not being completely fixed, affecting imaging.
An adjustable molybdenum target examination auxiliary device is designed, including a main stent, a molybdenum target mechanism and a correction mechanism. The correction mechanism is composed of a stent wall, a support member and a curved slide chute. The support member is slidally connected to the curved slide chute, which can apply thrust from other directions of the patient, prevent breast retraction and backward movement, and correct shoulder joint positioning through a shoulder traction rope.
Effectively prevent breast retraction and backward movement, ensure that more glandular tissue is fully imaged within the detector plate, reduce the possibility of misdiagnosis or misdiagnosis of the lesions, and prevent shoulder artifacts from overlapping, improving the accuracy of the examination.

Description
Technical Field
[0001] The present invention relates to the technical field of mammography examination equipment, and more specifically, to an adjustable mammography examination auxiliary device. Background Art
[0002] At present, for breast fixation in mammography, there is only the clamping force exerted on the breast by the breast compression device in the front of the body on a single side. Some patients instinctively shrink back due to fear of pain, or some patients have overly small breasts, resulting in incomplete fixation of some mammary glands within the projection range for complete imaging, causing missed or misdiagnosed lesions in some marginal areas of the mammary glands.
[0003] Meanwhile, during the mammography axial view examination, occasionally patients will move the shoulder on the side to be projected forward into the projection range to overlap with the mammary gland for imaging in order to relieve the compression pain, which affects the film viewing.
[0004] Therefore, there is an urgent need for an adjustable mammography examination auxiliary device to solve the above-mentioned problems. Summary of the Invention
[0005] The purpose of the present invention is to provide an adjustable mammography examination auxiliary device, which has a simple structure and is convenient to use, and can effectively assist patients in mammography examination.

The side of the bracket wall 2 close to the mammography mechanism 3 is a concave arc and is provided with an arc-shaped chute 8; the support member is slidably connected to the arc-shaped chute 8.
[0026] Currently, for breast fixation in mammography examinations, there is only the clamping force exerted by the breast compression device in front of the body on one side, which is likely to cause missed diagnosis or misdiagnosis of lesions in some marginal areas of the breast. By setting the bracket wall 2 and the support member, the support member can exert a thrust force from other directions of the patient, preventing the breast from retracting and moving backward, avoiding the patient's instinctive backward retraction due to fear of pain or the inability to completely fix some breasts of some patients due to their too small size, so that more glandular tissues can be completely imaged within the range of the detector flat panel; and the support member slidably connected to the arc-shaped chute 8 can be adjusted according to actual needs, with strong adaptability. It can be understood that the mammography mechanism 3 is a common mammography detection and irradiation device on the market; a side door that can be opened and closed is provided on the side of the bracket wall 2 opposite to the notch for personnel to enter and exit; an opening is provided on the bracket wall 2 for the irradiation tube ball to pass through; a base for auxiliary stability is provided at the bottom of the bracket wall 2.
