It is about the diagnostic device.

In general, breast adenocarcinoma or breast cancer is a major medical problem, especially for women over the age of 35. These breast cancers are not only a major cause of increased mortality in women, but also a cause of disability, psychological shock and economic loss.

According to academic reports, it is estimated that 1 in 8 people in the United States can develop the disease in their current lifetime. In addition, many women with this disease eventually die from direct or indirect complications from the disease.

Therefore, not only should we do our best to prevent breast cancer such as this, but also periodic diagnosis is required so that it can be detected early.

On the other hand, mammography, which is a breast cancer diagnostic machine, as an equipment necessary for early diagnosis of breast cancer is disclosed in Korean Patent Application Publication No. 2000-0066850.

In addition, the present invention includes a photographing aid device 20 installed on the image receptor 16 to pull the breast toward the rear by vacuum suction and maintain the pulled state.

As shown in Figs. 4 and 5A, the photographing auxiliary device 20 includes a cylindrical suction port 21 for adsorbing breasts. The adsorption port 21 has an opening 21a and an internal space through which a part of the breast can be inserted, and can be adsorbed without a vacuum suction means, but a vacuum on the opposite side of the opening 21a so that more reliable adsorption can be achieved. The vacuum hose 25a connected to the pump 25 is fixed.

Further, an air hole 21b leading to the inside is formed in the suction port 21, and the air hole 21b is opened and closed with a stopper 21c. The air hole 21b and the stopper 21c are for releasing the adsorption state of the adsorption port 21.

The adsorption port 21 of this configuration is preferably made of transparent glass or silicon so that the X-ray can pass.

The adsorption port 21 is detachably installed on the fixture 22, and a plurality of adsorption ports 21 of different sizes are provided, and can be selectively attached or detached according to the size of the breast of the subject. Detachable configuration, for example, can be configured by forming a male screw portion (22a) in the fixture 22 and a female screw portion (21d) in the suction port (21). Although not shown, male and female locking projections and locking grooves It can also be detachable by fitting type using

The suction port 21 and the fixture 22 are movable forward and backward on the image receptor 16 by a pulling mechanism 23.

The pulling mechanism 23 is installed on the upper surface of the rear side of the image receptor 16 and includes a housing 23a fixed on the image receptor 16.

In the housing 23a, a moving member 23c having a rack size 23b formed on an upper surface thereof is installed to be movable in the front and rear directions, and the rack size 23b of the moving member 23c has a housing 23a. The pinion gear 23d installed inside is meshed, and the pinion gear 23d is fixed to the shaft of the reduction motor 23e installed in the housing 23a and rotates at reduced speed by driving the reduction motor 23e.

The moving member 23c and the fastener 22 are connected by a connecting member 24. By means of the connecting member 24, the movement of the moving member 23c in the forward and backward directions is transmitted to the fixture 22, so that the suction port 21 and the fixture 22 can be moved forward and backward.

In this case, the connecting member 24 is preferably composed of a coil spring. One end of the coil spring is fixed to the moving member 23c, and the other end of the coil spring is fixed to the fixture 22, thereby connecting the fixture 22 and the moving member 23c.

The coil spring, which is the connecting member 24, can set a spring force (tensile force) by selecting a material and a diameter of the coil during manufacture. Therefore, it is preferable to set the spring force of the coil spring, which is the connection member 24, to minimize pain when the breast is vacuum-sucked and pulled through the suction port 21, and the pressure for compressing the breast with a conventional compression member is about 20. Considering that it is ㎏/㎠, set the spring force so that it can be tensioned when the pulling force of about 10~15kg/㎠ which is weaker than this is applied.

The vacuum hose (25a) connecting the suction port (21) and the vacuum pump (25) is installed to penetrate the center of the fixture (22), the connecting member (24) and the moving member (23c) to operate the pulling mechanism (23). Do not disturb the city. To this end, a through hole is formed in the central portion of the fixing tool 22 and the moving member 23c.

The function of the breast cancer diagnosis device configured in this manner will be described with reference to FIGS. 5A to 5C.

First, as shown in (a) of FIG. 5, the breast of the person to be photographed is brought into close contact with the suction port 21 of the photographing auxiliary device 20 installed on the image receptor 16, and the vacuum pump 25 is driven. If so, a vacuum acts in the suction port 21 through the vacuum hose 25a, so that the breast can be firmly vacuum-adsorbed. Since it is adsorbed by vacuum, pain can be reduced compared to a method of directly pressing with a conventional compression member.

Subsequently, when the reduction motor 23e is driven as shown in FIG. 5B, the pinion gear 23d rotates, and the pinion gear 23d is the rack size gear 23b of the moving member 23c. Because it is engaged with, it is possible to move the moving member 23c in the direction of the arrow (the rear of the image receptor 16).

Accordingly, the fixing member 22 connected by the moving member 23c and the connecting member 24 is also moved, and the adsorption hole 21 fixed to the fixing member 22 moves backward to move the breast onto the image receptor 16. Is pulled backwards. At this time, the force to pull the breast is set to be about 10 to 15 kg/cm 2, which is lower than the pressure of 20 kg/cm 2 pressed by a conventional compression member, so it is possible to reduce pain when pulling.

The setting of the pulling force can be achieved by configuring the connecting member 24 with a coil spring, and setting the spring force at the point of tension when the coil spring is pulled to about 10 to 15 kg/cm 2.

Therefore, as shown in (c) of FIG. 5, by driving the reduction motor 23e, the moving member 23c is moved in the direction of the arrow to pull the suction port 21, and the coil spring, which is the connecting member 24, is By stopping the driving of the reduction motor 23e at the point of tension, the pain in the breast can be maintained within the range of about 10 to 15 kg/cm 2.

Even when the driving stop of the reduction motor 23e is delayed due to the operator's carelessness, only the coil spring, which is the connecting member 24, is tensioned when the pulling force is 10-15 kg/cm 2 or more, so the pain in the breast does not increase. Compared to a compression method using a compression member, pain can be reduced.

After completing the X-ray photographing, when the driving of the vacuum pump 25 is stopped and the stopper 21c blocking the air hole 21b of the suction port 21 is removed, the suction port ( 21) Since air is introduced into the interior and the vacuum adsorption state is released, the suction port 21 can be separated from the breast of the subject.
