Detailed Description
In order to make the objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures 2 to 7 are described in detail below.
As shown in fig. 2, the breast compression device of the present invention includes a compression plate 1 and an identifier, in the embodiment of the present invention, the identifier is preferably a compression joint 2, the mounting end of the compression plate 1 is connected with the compression joint 2 in a matching manner, a protrusion 3 is provided on the end surface of the mounting end of the compression plate 1, and the identification of the compression plate is realized by the matching use of the protrusion 3 and the compression joint 2.
The mammary machine system (not shown) comprises a control unit and the mammary gland compression device, wherein the control unit receives an electric signal provided by the mammary gland compression device and identifies a compression plate according to the electric signal. In an embodiment of the present invention, the control unit is a geometric motion control unit GCU, but is not limited thereto.
Example one
As shown in fig. 3, a protrusion 31 is disposed on an end surface of the mounting end of the compression plate 11, the protrusion 31 is an integral structure, when the compression plate 11 is connected to the compression joint 2, the protrusion 31 presses the two triggers 4 in the compression joint 2 to generate a first electrical signal and output the first electrical signal, and the mammary gland machine system determines that the compression plate 11 is connected to the compression joint 2 according to the first electrical signal.
Referring to fig. 4, a plurality of triggers 4 are provided in the compression fitting 2, the triggers 4 being disposed opposite the protrusions 31 such that the protrusions 31 press the triggers 4 when the compression paddle 11 is coupled to the compression fitting 2. In this example 1, the number of the triggers 4 is 9, and they are arranged in a rectangular array, and in this case, the mammary machine system can recognize up to 511 kinds of compression plates.
Each trigger 4 corresponds to a switch element (not shown in the figure), when the trigger 4 is pressed by the protrusion 31, the switch element corresponding to the pressed trigger 4 is conducted, so that an electric signal output is formed, and the mammary machine system identifies the compression plate according to the electric signal. The switching element is a known element in the art, such as a microswitch, a proximity switch or a hall switch, and will not be described in detail herein.
By adopting the identification mode in the invention, the different shapes of the bulges are only needed to be arranged on the end surfaces of the mounting ends of the different compression plates, and the different shapes of the bulges press the triggers at different positions, so that different electric signal outputs are formed, and the mammary machine system can judge different compression plates.
The following describes in detail the identification process of the breast compression apparatus according to the present invention.
As shown in fig. 5, firstly, the compression plate 11 is installed in the compression joint 2, the protrusion 31 on the compression plate 11 presses the trigger 4, the switch element corresponding to the pressed trigger 4 is turned on, so as to form a first electrical signal output, the geometric motion control unit GCU of the mammary machine system receives and judges the first electrical signal, so as to identify the corresponding compression plate 11, and a program applicable to the compression plate 11 is called to prepare for the next operation; when the geometric motion control unit GCU does not judge the first electric signal, an alarm signal is sent out, the mammary machine system stops working, and a technician waits for checking.
Example two
This embodiment is substantially the same in structure as embodiment 1, except that the number of projections provided on the end surface of the compression paddle mounting end is different. As shown in fig. 6, in this embodiment, a protrusion 32 is disposed on an end surface of the mounting end of the compression plate 12, in this embodiment, the protrusion 32 includes a first protrusion 321 and a second protrusion 322, the first protrusion 321 and the second protrusion 322 are in a separated structure, and the trigger 4 is touched and pressed together by the first protrusion 321 and the second protrusion 322 to form an electrical signal output. By changing the shape of the first protrusion 321 and/or the second protrusion 322, the protrusion 32 presses different triggers to form different electrical signal outputs corresponding to different compression plates, so that the mammary machine system can recognize different compression plates.
EXAMPLE III
This embodiment is substantially the same as embodiment 1, and differs only in the number and arrangement of the triggers in the compression fitting. Referring to fig. 7, 7 triggers are arranged in the compression joint 2, and the 7 triggers are arranged in a circular array, that is, 6 triggers 41-46 are uniformly distributed on the circumference by taking the trigger 40 as the center of a circle. In this case, the mammography system can recognize a maximum of 127 compression plates, and the number of triggers is reduced by 2 compared to the first embodiment, but the number of compression plates that the mammography system can recognize is reduced by 384. It follows that the number of compression plates that can be identified by the breast machine system can be extended to a large extent by varying the number of triggers.
Although the present invention is illustrated only in the case of embodiments 1 to 3, in other embodiments, the number of projections on the end surface of the compression paddle mounting end may be more, and the shape of the projections may be other conventional shapes, such as a circle, triangle, or other polygon; correspondingly, the number of the triggers can be set differently according to actual needs, and the arrangement mode can be conventional two-dimensional array arrangement.
According to the mammary gland compression device provided by the invention, the end surface of the mounting end of the compression plate is provided with different bulges to trigger different triggers in the compression joint, so that different compression plates are identified; by increasing the number of triggers in the compression joint, the number of compression plates which can be identified by the mammary machine system can be greatly expanded. The invention utilizes hardware structure to identify different compression plates, compared with an image identification mode, the identification mode of the invention is simple and reliable, and the cost is low.
The foregoing is merely a preferred embodiment of the invention and is not intended to limit the invention in any manner. Those skilled in the art can make numerous possible variations and modifications to the present invention, or modify equivalent embodiments, using the methods and techniques disclosed above, without departing from the scope of the present invention. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are still within the scope of the protection of the technical solution of the present invention, unless the contents of the technical solution of the present invention are departed.
