Description

[Detailed description of the invention] (a) Industrial application field The present invention is used in the field of medical diagnostic equipment or connectors.

This invention is based on MRI (magnetic resonance imaging)-CT
The present invention relates to an apparatus, and particularly to connection with an antenna connection stand when guiding a top plate carrying a subject into a gantry.

(b) Prior art In MRI-CT equipment, several types of antenna coils are prepared in order to obtain images of each part of the subject to be examined. If placed nearby, these antennas can be quickly set on the subject.

Such an antenna connection table is connected to the top plate on which the subject is placed, and moves together with the top plate inside the tunnel of the gantry. Furthermore, since an amplifier for amplifying the detected signal may also be incorporated inside the connecting stand, it must be connected to the top plate.

(c) Problems that the invention aims to solve By the way, if the connecting table and the top plate are still connected, if the bed device is lowered to remove the patient after diagnosis, the device will be damaged and There are also problems such as harm to the examinee.

The purpose of this invention is that when the top board carrying a subject enters the inspection equipment or near the tunnel of the gantry, it is automatically connected to the antenna connection base, and when it is pulled out from the inspection equipment, it is automatically connected. MRI-CT with a structure that allows the connection to be released
The purpose is to provide equipment.

(d) Means for Solving the Problems The above-mentioned purpose is to provide an MRI-CT apparatus equipped with an antenna connection stand movably placed within the tunnel of the gantry and a top plate movable within the tunnel. A connecting protrusion piece provided on the gantry side end of the top plate, a connecting hook that is supported by a pin on the antenna connection base and can be engaged with the connecting protrusion piece, and a connecting hook provided on a fixed part in the tunnel. This is accomplished by providing a cam contact piece and connecting and releasing the connecting projection piece and the connecting hook by moving the top plate.

(E) Function The antenna connection base and the top plate constitute the paired elements of the coupling hook, the hook body is supported by a pin, one end of which becomes a hook for another paired element, and the other end driven by the cam contact. Spring supported. By contacting and separating the antenna connecting base and the top plate, the other end of the hook body causes the hook portion at one end to perform an attachment/detachment action.

(F) Embodiment A preferred embodiment of the present invention will be described with reference to FIGS. 1 to 4.

FIG. 5 is an overall schematic diagram of the MRI-CT apparatus.

1 is an inspection device or a gantry, 1' is a tunnel section, 3 is a top plate, 2 is a bed device with functions for vertical and horizontal movement of the top plate 3, 4 is a subject, and 5 is a head of one case. and 6 indicate an antenna connection stand.

FIG. 1 is a main bottom view showing one embodiment of the present invention, and FIG. 2 is a sectional view taken along the line - in FIG. 1. Further, FIGS. 3 and 4 are diagrams illustrating the operation mode according to the present invention.

In FIG. 1, when the top plate 3 moves in the direction of arrow B, its tip comes into contact with the connecting table 6 and pushes the connecting table 6.

The hook 8 has a fulcrum 9, and when the hook 8 makes contact as described above, the spring force of the sponge 10 moves the arrow C to the fulcrum 9.
When the hook 8 rotates in the direction and passes the end of the contact piece of the cam 11, the hook 8 catches on the protrusion 7 provided on the top plate 3, and the top plate 3 and the connecting base 6 are connected as shown in FIG.

When the top plate 3 moves in the opposite direction to the arrow B direction, the tip of the hook 8 connects with the inclined end of the contact piece of the cam 11 to rotate in the opposite direction to the arrow C direction, as shown in FIG. will be canceled.

Although not shown in the drawings, it is possible to incorporate an amplifier for amplifying detected signals inside the antenna connection stand 6, and it is also possible to mount a head antenna coil or the like.

(g) Effects According to the present invention, the connection between the top plate and the connecting base does not require manual effort and does not require any effort, and since the connection between the top plate and the connecting base is automatically disconnected, it is easy to remove the connection. No need for attention. Furthermore, there is no risk of damaging device parts and there is no risk of harm to the subject.
