DETAILED DESCRIPTION

[0028] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0029] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations such as "include" or "comprising", etc., will be understood to include the stated elements or components but not to exclude other elements or other components.

[0030] Example 1

[0031] Reference Figures 1-9 The breast positioning and compression device for breast examination of the present invention includes a breast camera body 1, a camera cassette 11 is provided on the breast camera body 1, a breast positioning and compression plate 12 is provided above the camera cassette 11, and a filter 111 is overlapped on the top surface of the camera cassette 11. The function of the filter 111 is to convert X-rays into a rigid beam with a relatively uniform energy distribution, thereby reducing the X-ray radiation dose of the examinee, and can also optimize the energy spectrum of the rays, absorb low-energy X-rays, and reduce scattered rays, thereby increasing the quality of the patient's mammographic imaging. A breast auxiliary positioning device 2 is installed at the front edge of the camera cassette 11. The breast auxiliary positioning device 2 includes two seat plates 21 respectively fixed on the left and right end surfaces of the camera cassette 11, a breast fold flattening structure 22 installed between the two seat plates 21, and a dial shaft 23 installed between the two seat plates 21.

[0032] In the present invention, a convex plate 211 is integrally formed on the seat plate 21, and the convex plate 211 is in an upward convex shape. A guide groove 2111 is provided on the top side end face of the convex plate 211. The breast fold flattening structure 22 passes through the two guide grooves 2111, so that the breast fold flattening structure 22 is confined between the two seat plates 21.

[0033] Specifically, a connecting plate 212 is fixed between the two seat plates 21 by bolts. The connecting plate 212 is in contact with the front end surface of the camera cassette 11 and is fixedly connected by bolts, so that the breast auxiliary positioning device 2 can be more firmly fixed on the breast camera body 1.

[0034] In the above scheme, the breast fold flattening structure 22 includes a sleeve rod 221 with a flat rod structure, a rotating shaft 222 inserted into the sleeve rod 221 from the side end and rotatably connected to the sleeve rod 221, and a plurality of shifting pins 223 mounted on the rotating shaft 222.

[0035] Specifically, the sleeve rod 221 passes through the guide groove 2111 and is slidably connected to the protruding plate 211. A baffle 2212 is fixed to both ends of the sleeve rod 221 by bolts. The baffle 2212 is located on the outside of the protruding plate 211, so that the sleeve rod 221 is constrained between the two protruding plates 211 under the action of the baffle 2212, preventing the sleeve rod 221 from escaping from the protruding plate 211. A plurality of sleeve grooves 2211 are formed at the bottom end of the sleeve rod 221. The shifting post 223 is sleeved inside the sleeve grooves 2211. A shaft hole 2213 is formed on the side end surface of the baffle 2212. The shaft hole 2213 sequentially passes through the baffle 2212 and the plurality of sleeve grooves 2211. The rotating shaft 222 extends into the shaft hole 2213 and is rotatably connected to the sleeve rod 221.

[0036] Furthermore, a square shaft 2221 is integrally formed at the end of the rotating shaft 222, and the square shaft 2221 passes through the dial column 223. A dial handle 2222 is integrally formed at the head end of the rotating shaft 222. The dial column 223 is a cylindrical structure, and a transparent square hole 2231 is opened on the side end surface of the dial column 223. The square shaft 2221 passes through the square hole 2231. When the dial handle 2222 is rotated, the dial handle 2222 can drive the rotating shaft 222 and the square shaft 2221 to rotate together, so that the dial column 223 is in the sleeve groove 2 When the patient's breast is compressed by the breast positioning and compression plate 12, the seat plate 21 rotates. Under the action of gravity, the seat plate 21 can be in close contact with the upper surface of the breast, thereby allowing the lever 223 to be in close contact with the skin. As a result, the lever 223 can pull the skin of the breast during rotation, so that wrinkles caused by the compression of the breast positioning and compression plate 12 can be flattened by the pull of the lever 223, thereby preventing skin wrinkles from affecting the results of mammographic imaging during breast examinations. A plurality of convex balls 2232 are integrally formed on the outer surface of the lever 223. When the lever 223 rotates, the convex balls 2232 can pull the skin. This increases the friction between the lever 223 and the breast skin, thereby increasing the pulling effect on the skin on the breast surface.

[0037] In addition, a supporting plate 2214 is integrally formed on the rear end face of the sleeve rod 221, and a protruding edge 121 is integrally formed at the front edge of the breast positioning compression plate 12. When the breast positioning compression plate 12 moves downward, the bottom surface of the protruding edge 121 can be against the top surface of the supporting plate 2214, so that when the breast positioning compression plate 12 is used to compress the breast during positioning, the breast positioning compression plate 12 can press the breast fold flattening structure 22, so that the lever 223 on the breast fold flattening structure 22 can always be in contact with the epidermis of the breast, so that the rotation of the lever 223 can smoothly eliminate the wrinkles generated on the epidermis of the breast.

[0038] Example 2

[0039] In a preferred embodiment, the breast fold flattening structure 22 is located above the dial shaft 23, and a convex end 2112 is integrally formed on the front end surface of the bottom of the convex plate 211. The dial shaft 23 passes through the two convex ends 2112 and is rotatably connected to the convex ends 2112. The dial shaft 23 is located at the front end edge of the filter 111, and the top of the dial shaft 23 is flush with the top surface of the filter 111, so that when the patient puts the breast on the filter 111, the bottom of the breast will be placed on the dial shaft 23, and both ends of the dial shaft 23 are flush. A rotating handle 231 is fixed by bolts, and a plurality of rubber sleeves 232 are sleeved on the outer surface of the dial shaft 23. When the patient places the breasts on the filter 111, the examiner can turn the rotating handle 231 to cause the rotating handle 231 to drive the dial shaft 23 to rotate together. The rubber sleeves 232 on the dial shaft 23 can push the patient's breast toward the top of the filter 111 as much as possible due to the friction force of the rubber sleeves 232, thereby allowing the mammogram to capture more tissue in the breast.

[0040] The working principle of the breast positioning and compression device for breast examination of the present invention is specifically as follows:

[0041] After the breast fold flattening structure 22 is pushed upwards to slide to the top position of the convex plate 211, the patient can pass the breast from under the breast fold flattening structure 22 and place it on the top of the filter 111, so that the patient's breast can be positioned on the camera cassette 11, and then the breast fold flattening structure 22 is loosened, so that the breast fold flattening structure 22 can move downward along the guide groove 2111 under the action of gravity, so that the breast fold flattening structure 22 can be placed on the patient's breast, and finally the breast positioning compression plate 12 is controlled to compress the patient's breast, thereby By reducing the thickness of the patient's breast, the breast positioning and compression plate 12 can press the breast fold flattening structure 22 downward under the action of the convex edge 121, so that the dial post 223 on the breast fold flattening structure 22 can always be in contact with the epidermis of the breast. At this time, by rotating the dial handle 2222, the dial handle 2222 can drive the rotating shaft 222 and the square shaft 2221 to rotate together. As the dial post 223 rotates, the dial post 223 can pull the skin of the breast, so that the wrinkles caused by the compression of the breast can be flattened, thereby preventing the occurrence of skin wrinkles that will affect the results of mammographic imaging during breast examination.
