[0014] The present invention will be described below according to the embodiments shown in the drawings. The embodiments disclosed this time can be considered illustrative in all aspects and are not restrictive. The scope of the present invention is not limited by the description of the following embodiments, but is only shown by the scope of the claims, and includes all modifications having the same meaning as the scope of the claims and within the scope of the claims.

[0015] In order to solve the technical problem that the existing X-ray diagnostic device has a large width in the lying position on the bed, which is not conducive to use in a room with a small width, the following provides an X-ray diagnostic device.

[0016] (First Embodiment)

[0017] Figure 3 It is a schematic structural diagram of the X-ray diagnostic device of this embodiment. Figure 3 (A) is the front view. Figure 3 (B) is the side view. Combining Figure 3 , the X-ray diagnostic device at least includes:

[0018] Column 1;

[0019] Bed part 3, movably connected to column 1, for carrying the subject;

[0020] X-ray detection part, movably arranged on both sides of bed part 3, including X-ray generator unit 5 and X-ray detector unit (not shown in the figure) for detecting the X-ray passing through the subject; Moving part, fixed to column 1 on one side and connected to bed part 3 and X-ray detection part on the other side, enabling bed part 3 to move together with the X-ray detection part along the X-ray irradiation direction, and the X-ray irradiation direction is at least one of the direction approaching the X-ray generator unit that irradiates X-rays and the direction away from the X-ray generator unit. When bed part 3 maintains an upright posture, the X-ray irradiation direction is the horizontal direction.

[0021] It should also be noted that: Column 1 can be replaced by other components with a supporting function, such as a boom, gantry, etc. The strength and size of the supporting part are increased according to actual needs.

[0022] Figure 4 It is a schematic operation diagram of the X-ray diagnostic device of this embodiment. Figure 4 The arrow in indicates the movement direction of bed part 3, indicating that bed part 3 rotates from the lying posture to the upright posture.

[0023] Figure 5 It is a schematic decomposition diagram of the operation of the X-ray diagnostic device of this embodiment. Figure 5 The arrow in is the movement direction of bed part 3 and the X-ray detection part. Figure 5 (a), Figure 5 (b), Figure 5 (c) respectively represent the lying posture, rotational movement to the upright posture, and horizontal movement to the yielding posture of bed part 3. Among them, the yielding posture means that the X-ray generator unit moves towards the direction away from the wall, thus forming a posture that allows doctors to pass through.

[0024] Combining Figure 5 (a) toFigure 5 (b), the moving part rotates the bed part 3 to move the bed part 3 to the standing position. As the bed part 3 rotates, the X-ray detection part housed in the bed part 3 moves to the standing position. Combining Figure 5 (b) to Figure 5 (c), the moving part horizontally moves the bed part 3 and the X-ray detection part, thereby changing the distance between the X-ray detection part and the wall, providing a wider walking space for the doctor.

[0025] The stroke of the moving part moving the bed part 3 and the X-ray detection part in the horizontal direction can reach 400 mm, so that the space required by the bed part 3 in the head side and foot side directions is reduced by 400 mm. Even in an X-ray photography room with a width of 4000 mm, the X-ray diagnostic device of this embodiment can be used normally.

[0026] Figure 6 is a partial perspective view of the improved part of the X-ray diagnostic device of this embodiment compared with the existing X-ray diagnostic device. Combining Figure 1 and Figure 6 , the moving part includes:

[0027] A turntable part 2 rotatably connected to the column 1;

[0028] A sliding table part 6 linearly movably connected to the turntable part 2, and the bed part 3 and the X-ray detection part are both connected to the sliding table part 6;

[0029] A first rotation unit 11 connecting the column 1 and the turntable part 2 to make the turntable part 2 rotate, so that the bed part 3 rotates to the standing position;

[0030] A linear drive unit 7 connecting the turntable part 2 and the sliding table part 6 to make the sliding table part 6 move linearly, so that the bed part 3 and the X-ray detection part move together along the direction of the X-ray.

[0031] The sliding table part 6 includes a guide part 61, a sliding part and a bed seat 62. The guide part 61 is fixedly connected to the turntable part 2, the sliding part is slidably connected to the guide part 61, the bed seat 62 is fixedly connected to the sliding part, and the bed seat 62 extends in a direction away from the turntable part 2.

[0032] The bed part 3 is fixedly connected to one side of the bed seat 62 away from the turntable part 2, and the X-ray detection part is connected to the bed seat 62 or the bed part 3.

[0033] The linear drive unit 7 can adopt an electric gear-rack sliding table. Among them, the electric gear-rack sliding table includes a rack, a gear and a motor. The rack is parallel to the guide part 61 and fixedly connected to the turntable part 2. The motor is fixedly connected to the sliding part, and the actuator of the motor is drivingly connected to the gear, and the gear meshes with the rack.

[0034] Other points that need to be noted are as follows:

[0035] The first rotating unit 11 uses an electric worm and worm gear turntable.

[0036] Alternatively, the first rotating unit 11 includes a rotating bearing and a driving member (not shown in the figure). The turntable portion 2 is rotatably connected to the column 1 through the rotating bearing. The driving member is fixed on the column 1 and is used to drive the turntable portion 2 to rotate.

[0037] The guiding portion 61 can adopt a slide rail, and the sliding portion can adopt a slider. The sliding portion is covered by the bed base 62, so the sliding portion is not visible in the figure.

[0038] The bed base 62 can adopt an L-shaped metal casting. The bed base 62 includes a first pedestal portion and a second pedestal portion that are perpendicularly connected to each other. The second pedestal portion is connected to one end of the first pedestal portion and extends in a direction away from the turntable portion 2. The first pedestal portion is fixedly connected to the sliding portion, and the second pedestal portion is fixedly connected to the bed portion 3.

[0039] (Second Embodiment)

[0040] The connection relationship between the column 1 and the bed portion 3 is changed. After the bed portion 3 rotates to the upright state, when the bed portion 3 and the X-ray detection portion are moved by the linear driving unit 7, it is easy to cause the center of gravity of the X-ray diagnostic apparatus to change, and the strength of the column 1 of the existing X-ray diagnostic apparatus may not meet the requirements of the X-ray diagnostic apparatus after the change of the center of gravity.

[0041] In order to increase the strength of the column 1, the following methods can be used:

[0042] Method 1: Identify the weak points of the force on the column 1 and perform reinforcement design.

[0043] Method 2: If the reinforcement of the column 1 is unqualified, increase the size of the column 1. For example:

[0044] Increase the wall thickness of the column 1;

[0045] Or increase the size of the column 1 along the width direction (the head-foot direction of the bed portion 3);

[0046] Or increase the size of the column 1 along the depth direction (the direction of the bed portion 3 facing the doctor).

[0047] Since there is a large space for the column 1 to increase its own size in the width direction of the X-ray diagnostic apparatus, this improvement will not affect the overall size of the X-ray diagnostic apparatus.

[0048] However, there is no space in the depth direction of the X-ray diagnostic apparatus to allow the column 1 to increase its own size. Therefore, this improvement will increase the overall size of the X-ray diagnostic apparatus.

[0049] In order to solve the problem of the increase in the overall size of the X-ray diagnostic apparatus in the depth direction, the second embodiment reduces the size of the support arm 4 in the depth direction, thereby reducing the depth size of the X-ray diagnostic apparatus. The specific structure of the second embodiment is described as follows.

[0050] Combined with Figure 3 and Figure 6 , the X-ray diagnostic apparatus further includes:

[0051] A support arm 4, one end of which is fixedly connected to the second rotation drive unit 41, and the other end is fixedly connected to the X-ray generator unit 5;

[0052] A second rotation unit 41, fixedly connected to the bed unit 3, rotates the support arm 4 to drive the X-ray generator unit 5 to rotate, so that the X-ray generated by the X-ray generator unit 5 is inclined to the X-ray detector unit. Among them, the second rotation unit 41 uses an electric worm and worm turntable.

[0053] The second rotation unit in the existing X-ray diagnostic apparatus usually includes structures such as a motor, a speed reducer, and a rack. Since the sizes of structures such as a motor, a speed reducer, and a rack in the depth direction are difficult to reduce, the X-ray diagnostic apparatus in this embodiment uses an electric worm and worm turntable to replace structures such as a motor, a speed reducer, and a rack. The electric worm and worm turntable has a smaller size in the depth direction, which can reduce the size of the support arm 4 in the depth direction, thereby reducing the size of the X-ray diagnostic apparatus in the depth direction.

[0054] (Third Embodiment)

[0055] When the bed unit 3 rotates to the upright position, the subject may fall and tumble from the bed unit 3. To solve this problem, the following improvements are made to the bed unit 3.

[0056] Figure 7 is a schematic structural view of the bed unit 3, Figure 7 (A) is the front view, Figure 7 (B) is the side view. Combined with Figure 6 、 Figure 7 , the bed unit 3 includes:

[0057] A guardrail 31, fixedly connected to both sides of the bed unit 3 and close to the subject's arms;

[0058] A strap assembly 32, the two ends of which are respectively arranged on both sides of the bed unit 3, perpendicular to the guardrail 31, and detachably connected to the bed unit 3 or the guardrail 31 for binding the subject's chest and abdomen.

[0059] The strap assembly 32 may adopt the structure of a car seat belt, which includes a strap releaser and a buckle respectively fixedly connected to both sides of the sleeping platform 3. The doctor pulls the strap out of the strap releaser and connects the free end of the strap to the buckle to complete the restraint of the subject.

[0060] (Fourth Embodiment)

[0061] Combination Figure 6 The existing sleeping platform 3 includes a shoulder pad assembly 33 movably connected to the sleeping platform 3. The shoulder pad assembly 33 is a flat plate shape used to press the shoulders of the subject. When the sleeping platform 3 is rotated to the standing position, the shoulders of the subject may fall forward, affecting the X-ray photography. In order to solve this problem, the following improvements are made to the sleeping platform 3.

[0062] Combination Figure 7 , the shoulder pad assembly 33 comprises:

[0063] The shoulder pressing part 34 has a straight rod shape, one end of which is movably connected to the bed part 3, and the other end of which extends toward the shoulders of the subject in a direction perpendicular to the bed part 3;

[0064] The shoulder-pulling portion 35 has a straight rod shape, one end of which is fixedly connected to the free end of the shoulder-pressing portion 34 , and the other end of which extends over the shoulders of the subject toward the chest of the subject.

[0065] Preferably, the connection portion between the pressing shoulder portion 34 and the pulling shoulder portion 35 is in an arc-shaped transition.

[0066] In this embodiment, the shoulder pressing part 34 is movably connected to the bed 3, which means that the shoulder pressing part 34 can move and rotate linearly along the surface of the bed 3, so as to cushion the shoulders of subjects of different body shapes.

[0067] The shoulder pressing part 34 and the sleeping platform part 3 can achieve the above purpose by connecting in a variety of ways, for example:

[0068] A damping slide rail is installed on the bed portion 3, a slider is installed on the damping slide rail, and the shoulder portion 34 is connected to the slider via a damping ball bearing, so that the shoulder portion 34 is allowed to move and rotate in a linear direction.

[0069] A two-degree-of-freedom robotic arm is installed on the bed portion 3 , and the shoulder pressing portion 34 is fixedly connected to the actuator of the two-degree-of-freedom robotic arm. The two-degree-of-freedom robotic arm is used to drive the shoulder pressing portion 34 to move and rotate in a linear direction.
