Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to an X-ray sample bracket for placing samples at multiple angles for taking all-round X-ray films of samples. Background Art

[0002] In the field of X-ray equipment, after the X-ray generator generates X-rays, the X-rays penetrate the irradiated object, then irradiate the detector, and finally obtain an image through the imaging system. During surgery, the cut tissue samples are often taken X-rays to detect the location of the lesion and evaluate the cutting effect. In this process, the part of the irradiated object that needs to be irradiated needs to be completely within the irradiation range of the X-rays. Every time an X-ray is taken, a perspective image of the irradiated object in a corresponding direction will be obtained. The image data reflected by the perspective data in one direction is relatively limited. If image data from different angles can be obtained, the actual situation of the irradiated object can be analyzed more accurately. It would be best if the images of the irradiated object in several mutually perpendicular perspective directions can be obtained. Since the irradiated object is generally irregular in shape, it is difficult for the operator to obtain mutually perpendicular images when actually positioning it. At the same time, this positioning process is very time-consuming and delays the operation time. Summary of the invention

[0003] The object of the present invention is to provide an X-ray sample holder for placing samples at multiple angles, which can be quickly positioned and take all-round X-ray films of the samples, in view of the defects of the existing sample holders.

[0004] In order to achieve the above object, the present invention adopts the following technical scheme:

[0005] An X-ray sample holder for placing samples at multiple angles includes a sample support frame for fixing the sample; the characteristic is that: the sample support frame is connected to at least three plane support frames, and different plane support frames support the sample support frame with different support planes, so that the sample on the sample support frame faces the vertical direction at different angles. Multiple support planes are formed by the plane support frame, and the fast switching of different support planes can make the sample face the shooting plane at different angles, thereby obtaining X-ray image data of multiple determined angles, which reflects the actual situation of the sample more completely and comprehensively.

[0006] The further feature is that the plane support frame is hinged on the sample support frame. The plane support frame and the sample support frame are hinged so that the plane support frame can be folded and stored when not in use, thereby reducing the volume of the bracket. At the same time, multiple plane support frames can be opened, and the plane where the sample support frame is located can be used as the shooting plane for X-ray shooting.

[0007] Furthermore: the support planes of the plurality of planar support frames converge at the same point, and through this convergence point, all the planar support frames can be conveniently positioned using a fastener, so that the plurality of planar support frames are connected together for easy assembly.

[0008] Preferred mode: three of the planar support frames are connected to the sample support frame; the support planes of the three planar support frames are perpendicular to each other. A three-dimensional sample includes projection images in three directions: X, Y, and Z. The support planes of the three planar support frames are perpendicular to each other. By placing and shooting the three support planes, X-ray image data of the sample in three directions of X, Y, and Z can be obtained, thereby obtaining complete and comprehensive sample image data. In addition, the image data is obtained by X-ray shooting with the plane where the sample support frame is located as the shooting plane, and this image data has the same angle as the image data in the first three mutually perpendicular directions. Therefore, the perspective images in the above four directions can be obtained quickly and accurately, which can more accurately reflect the actual situation of the sample.

[0009] Preferably, the sample support frame is a regular hexagon, and the three planar support frames are connected at intervals on three sides of the regular hexagon.

[0010] The planar support frame is in the shape of a rectangle connected to an isosceles right triangle; the isosceles right triangle and the rectangle are on the same plane; one side of the rectangle is connected to the side of the sample support frame, and the other opposite side is connected to the hypotenuse of the isosceles right triangle.

[0011] The above preferred structure can quickly construct a sample holder having three supporting planes that are perpendicular to each other, and the hinge connection and the triangular structure facilitate the positioning of the three plane support frames.

[0012] The further feature is that the sample support frame comprises an upper cover and a lower cover, the upper cover and the lower cover are provided with elastic films, and the sample is fixed between the two layers of elastic films. The sample support frame adopts a double-layer structure, and the sample can be quickly clamped and positioned on the sample support frame through the elastic film, and the positioning is accurate and not easy to shift.

[0013] Preferably, the upper cover and the lower cover are hinged together at one end and buckled at the other end. The hinge connection and buckle buckle mode make the clamping and positioning of the sample faster.

[0014] The present invention connects multiple planar support frames to a sample support frame, and supports the sample support frame with multiple different support planes to shoot X-ray images of samples at different angles, thereby solving the problem of rapid positioning, and also obtaining complete and comprehensive X-ray images of the samples, which can more accurately analyze the actual situation of the irradiated object. Preferably, the support planes of the three planar support frames are mutually perpendicular in pairs, and three mutually perpendicular image data are obtained by placing and shooting the three support planes. This structure ensures that the three projection directions of the irradiated object are precisely perpendicular to each other. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] An X-ray sample bracket for placing samples at multiple angles includes a sample support frame for fixing the sample, and at least three planar support frames hinged on the sample support frame, wherein different planar support frames support the sample support frame with different support planes, so that the sample on the sample support frame faces the vertical direction at different angles. Multiple support planes are formed by the planar support frame, and the rapid conversion of different support planes can make the sample face the shooting plane at different angles, thereby obtaining multi-angle X-ray image data, which reflects the actual situation of the sample more completely and comprehensively. Only X-ray images at at least three angles can fully and comprehensively reflect the actual situation of the sample. Therefore, the number of planar support frames in the technical solution of the present invention is not less than three. The planar support frame and the sample support frame are hinged, so that the planar support frame can be folded and put away when not in use, thereby reducing the volume of the bracket. At the same time, the multiple planar support frames are opened, and the plane where the sample support frame is located can be used as the shooting plane for X-ray shooting. The support planes of the multiple planar support frames converge at the same point, and through this convergence point, all the planar support frames can be conveniently positioned using a fastener, so that the multiple planar support frames are connected together for easy assembly.

[0020] Based on the above design ideas, the sample holder can be designed into a polygonal pyramid shape, with the sample support frame as the bottom surface and the plane support frame as the side surface. It can also be designed into other three-dimensional shapes.

[0021] The following is a preferred embodiment:

[0022] like Figure 1As shown, an X-ray sample holder for placing samples at multiple angles includes a regular hexagonal sample support frame 1 for fixing a sample 3 and three planar support frames 2.

[0023] The sample support frame 1 comprises an upper cover 11 and a lower cover 12, one end of the upper cover 11 and the lower cover 12 are hinged together by a sample hinge 13, and the other end is buckled. The upper cover 11 and the lower cover 12 are provided with elastic films, and the sample 3 is fixed between the two layers of elastic films. The sample support frame 1 adopts a double-layer structure, and the sample 3 can be quickly clamped and positioned on the sample support frame through the elastic film, and the positioning is accurate and not easy to shift.

[0024] The three planar support frames 2 are hinged at intervals on the three sides of the regular hexagonal sample support frame 1 through the tray hinges 4. The planar support frame 2 is in the shape of a rectangle connected to an isosceles right triangle; the isosceles right triangle and the rectangle are on the same plane; one side of the rectangle is connected to the side of the sample support frame, and the other opposite side is connected to the hypotenuse of the isosceles right triangle. The vertices of the three isosceles right triangles are connected together to support the sample support frame. After the three planar support frames are supported, the three supporting planes are perpendicular to each other. When not in use, the planar support frame can be folded and put away to reduce the volume of the bracket.

[0025] When in use, the sample is fixedly placed at the geometric center of the sample support. A three-dimensional sample includes projection images in three directions: X, Y, and Z. The support planes of the three planar support frames are perpendicular to each other. By placing and shooting the three support planes, the X-ray image data of the sample in the three directions of X, Y, and Z that are mutually orthogonal can be obtained, thereby obtaining complete and comprehensive sample image data. In addition, the image data obtained by X-ray shooting with the plane where the sample support frame is located as the shooting plane has the same angle as the image data in the first three mutually perpendicular directions. In addition, the perspective images in the above four directions can be obtained quickly and accurately, which can more accurately reflect the true situation of the sample.
