Movable support assembly, mammary radiography machine and mammary radiography machine pressing method

Abstract

The embodiment of the invention provides a movable support assembly, a mammary radiography machine and a mammary radiography machine pressing method. The movable support assembly comprises a movable support plate and a support rail, wherein a revolving shaft is arranged on the support rail, the movable support plate is movably connected to the support rail through the revolving shaft, and the movable support plate can move up and down through the revolving shaft; the back end of the support rail is connected to a fixed portion, the fixed portion comprises a force application part, and the force application part is used for applying downward force to the movable support plate so that the movable support plate can be upwarped relative to the horizontal direction in the initial state. According to the embodiment of the invention, the oppressing and releasing effect can be effectively improved, the comfort of patients is improved, the phenomenon that the examined body is extruded in oppressing is effectively improved, and the quality of imaging is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of medical devices, and in particular to a movable support assembly, a mammary gland machine, and a mammary gland machine compression method. Background technique [0002] A breast machine is a device that uses X-ray photography to check whether a patient's breast has lesions. A breast machine generally includes a compression plate assembly (hereinafter referred to as the compression plate) and a support plate assembly (hereinafter referred to as the support plate). When using a breast machine to examine a patient's breast, it is often necessary to use a compression plate to compress the breast to a certain thickness in order to improve the imaging quality. In the prior art, the compression plate and the support plate are arranged in parallel, and both the compression plate and the support plate are fixed structures. [0003] The applicant found in the process of implementing th...

Problems solved by technology

[0003] The applicant found in the process of implementing this application that: in the process of compressing the mammary glands with the compression board, due to the characteristics of the shape of the mammary glands, the thickness of the mammary glands near the breast wall is relatively large, and the roots of the mammary glands are easily squeezed out at the beginning of compression, resulting in Deterioration of image quality

In addition, since the compression plate and the support plate are arranged in parallel, as the compression plate is pressed downward, the compression plate will deform, especially the compression plate near the side of the breast wall will deform greatly, resulting in uneven thickness of the breast, which will also affect the breast to a certain extent. image quality
