[0030] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0031] In the description of this application, the directions or positional relationships of "horizontal", "vertical", "left", "right", "top", and "bottom" are based on the attached Figure 1 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0032] An embodiment of the present application provides an operating table. Figures 5 to 7The operating table includes a base 40, a column 50, a table assembly 10 and a tubular support arm 20. The column 50 is arranged on the base 40, the table assembly 10 is arranged on the column 50, and the table assembly 10 includes an upper surface and a lower surface; the tubular support arm 20 is connected to the table assembly 10, and the tubular support arm 20 meets the following conditions: the X-rays generated by the radiological imaging device can pass through the tubular support arm 20 along the propagation direction, and the maximum transmission thickness of the tubular support arm 20 in the propagation direction of the X-rays is less than or equal to 4 times the base wall thickness of the tubular support arm 20, that is, T max ≤D×4, where T max represents the maximum transmission thickness, D represents the base wall thickness, and the propagation direction of the X-ray is from the upper surface through the lower surface or from the lower surface through the upper surface.

[0033] Specifically, the tubular support arm 20 refers to a support arm made of a pipe. The tubular support arm 20 can be directly connected to the table top assembly 10 or connected to the table top assembly 10 through an intermediate connecting piece.

[0034] The tubular support arm 20 may be a support arm with uniform wall thickness or a support arm with non-uniform wall thickness. Figure 7 The uniform wall thickness support arm described in the embodiment of the present application refers to a support arm made of a tube with uniform side wall thickness. The basic wall thickness of the uniform wall thickness support arm is the distance D1 between the inner wall and the outer wall of the uniform wall thickness support arm. That is to say, the basic wall thickness of the uniform wall thickness support arm is the wall thickness of the tube commonly described, that is, D=D1.

[0035] See also Fig. 9 The non-uniform wall thickness support arm described in the embodiment of the present application refers to a support arm made of a tube with uneven side wall thickness. The basic wall thickness of the non-uniform wall thickness support arm is the maximum value D2 of the distance between the inner wall and the outer wall of the non-uniform wall thickness support arm. In other words, the basic wall thickness of the non-uniform wall thickness support arm refers to the maximum wall thickness of the tube with uneven side wall thickness, that is, D=D2.

[0036] The transmission thickness refers to the total thickness of the side wall of the tubular support arm 20 that the X-ray passes through in the propagation direction, excluding the thickness of the hollow area in the tubular support arm 20 that the X-ray passes through, for example, see Figure 7, the X-ray at B in the figure does not pass through the hollow area in the tubular support arm 20, so the thickness dimension T1 shown in the figure is the transmission thickness of the X-ray at B, and the X-ray at C in the figure passes through the hollow area in the tubular support arm 20, so the transmission thickness at C is the sum of the thickness dimension T2 of the side wall at the top and the thickness dimension T3 of the side wall at the bottom, that is, the transmission thickness at C = T2 + T3. Since the transmission thickness at different positions of the tubular support arm 20 is not completely the same in the same propagation direction of the X-ray, the maximum transmission thickness refers to the maximum value of the transmission thickness in the same propagation direction of the X-ray.

[0037] A support member can be provided on the tubular support arm 20 , and the support member can be a support plate, for example, a leg support plate for supporting the patient's legs, a pelvic support plate for supporting the patient's pelvis, etc. The support member can also be various traction devices and the like provided on the tubular support arm 20 .

[0038] According to research, the main reason for the uneven transmission and abnormal development of pipes in the X-ray diagnosis process in related technologies is the uneven distribution of the transmission thickness of the pipes. For example, please refer to Figure 1 and Figure 2 , taking a square tube with a side length of 20 mm (the "mm" in this application represents the length unit of millimeter) and a wall thickness of 2.5 mm in the related art as an example, when the propagation direction of the X-ray is parallel to the left and right walls of the square tube, the transmission thickness of the X-ray passing through the left wall or the transmission thickness of the X-ray passing through the right wall is much greater than the transmission thickness of the X-ray passing through the top and bottom walls of the square tube. The transmission thickness of the square tube has a serious mutation at the left and right walls. For details, please refer to Figure 2 , square tube in Figure 2 The transmission thickness in the range of the horizontal coordinates 0mm-2.5mm and 17.5mm-20mm is 20mm, which is 8 times the basic wall thickness of the square tube of 2.5mm. There is a serious mutation in the transmission thickness in the range of the horizontal coordinates 0mm-2.5mm and 17.5mm-20mm. For another example, please refer to Figure 3 and Figure 4 Taking a circular tube with a diameter of 20 mm and a wall thickness of 2.5 mm in the related art as an example, the transmission thickness on the left and right sides of the circular tube is greater than the transmission thickness in the middle area of ​​the circular tube. There is also a serious mutation in the transmission thickness on the left and right sides of the circular tube. For details, please refer to Figure 4 , the round tube is Figure 4The transmission thickness at the horizontal coordinates of 2.5mm and 17.5mm is 13.22mm, which is about 5.28 times the basic thickness of the round tube of 2.5mm. The mutation of the transmission thickness at the horizontal coordinates of 2.5mm and 17.5mm is the largest, and the mutation of the transmission thickness near the horizontal coordinates of 2.5mm and 17.5mm is also relatively large. Therefore, when the X-ray passes through the mutation position of the square tube or round tube mentioned above, the development on the film will show obvious abnormal development, which will cause the uneven development of the entire square tube or round tube on the film. If the mutation is larger, the abnormal development after transmission will be more obvious, which may cause misjudgment by doctors in severe cases.

[0039] The maximum transmission thickness of the tubular support arm 20 in the propagation direction of the X-rays in the embodiment of the present application is less than or equal to 4 times the basic wall thickness of the tubular support arm 20, that is, the distribution of the transmission thickness of the tubular support arm 20 is roughly uniform without obvious mutations. Therefore, after the X-rays pass through the tubular support arm 20, the development on the film is relatively uniform and there will be no abnormal development phenomenon, thereby greatly improving the imaging effect of the radiological imaging equipment.

[0040] The propagation direction of the X-rays shown in the drawings of the embodiments of the present application is vertical. It can be understood that in some embodiments, the propagation direction of the X-rays can also be oblique at a certain angle to the vertical.

[0041] The tubular support arm 20 of the embodiment of the present application can be made of any material that is transparent to X-rays. For example, the tubular support arm 20 can be made of a carbon fiber material. In other words, the tubular support arm 20 can be a carbon fiber tubular support arm.

[0042] The number of the tubular support arm 20 can be one or more. Figure 5 When a plurality of tubular support arms 20 are provided on the operating table, the plurality of tubular support arms 20 may be spaced apart along the width direction of the table top assembly 10 .

[0043] In one embodiment, the maximum transmission thickness of the tubular support arm 20 in the propagation direction of the X-ray is less than or equal to the base wall thickness of the tubular support arm 20. times, that is It has been found through research that this size range can greatly improve the uniformity of the transmission thickness distribution of the tubular support arm 20 , thereby making the development of X-rays on the film more uniform after passing through the tubular support arm 20 .

[0044] In one embodiment, the lower surface is connected to the column 50, and the propagation direction of the X-ray is perpendicular to the upper surface and the lower surface.

[0045] In one embodiment, please refer to Figure 8The transmission thickness variation of the tubular support arm 20 in the propagation direction of the X-ray is at least partially continuous, without any step jump.

[0046] Specifically, from Figure 2 It can be seen from the transmission thickness distribution diagram of the square tube in the prior art that the transmission thickness of the square tube in the prior art decreases from 20 mm to 5 mm, and there is an obvious step jump in the transmission thickness.

[0047] The transmission thickness variation of the tubular support arm 20 of the present application in the propagation direction of the X-ray is at least partially continuous, that is, the variation curve of the transmission thickness of the tubular support arm 20 in the propagation direction of the X-ray is a continuous function. Figure 8 The transmission thickness distribution diagram of the tubular support arm 20 of the present application is shown as an example, that is, when Figure 8 When the change of the lateral coordinate in is very small, the change of the transmission thickness caused is also very small, and there is no step jump in the change of the transmission thickness of the tubular support arm 20.

[0048] In one embodiment, please refer to Figure 7 , Figures 9 to 12 The tubular support arm 20 is a polygonal tubular support arm, that is, the cross-section of the polygonal tubular support arm is a polygon. The polygonal tubular support arm has a strong moment resistance and is easy to manufacture.

[0049] In one embodiment, please refer to Figure 7 , Figures 9 to 11 , the polygonal tubular support arm is a rhombus-shaped tubular support arm, that is, the cross-section of the polygonal tubular support arm is in the shape of a rhombus.

[0050] The propagation direction of the X-rays can be perpendicular to any side wall of the rhombus tubular support arm, or can be oblique to any side wall of the rhombus tubular support arm, but the propagation direction of the X-rays is not parallel to any side wall of the rhombus tubular support arm, or in other words, the X-rays penetrating from one end of any side wall of the rhombus tubular support arm cannot pass out from the other end opposite to the same side wall, thereby ensuring that the maximum transmission thickness of the rhombus tubular support arm in the propagation direction of the X-rays is less than or equal to 4 times the basic wall thickness of the rhombus tubular support arm, or that the maximum transmission thickness of the rhombus tubular support arm in the propagation direction of the X-rays is less than or equal to 1 / 2 of the basic wall thickness of the rhombus tubular support arm. times.

[0051] In one embodiment, please refer to Figure 7 , one of the radial center lines of the rhombus-shaped tubular support arm is perpendicular to the propagation direction of the X-ray.

[0052] Specifically, Figure 7Taking the diamond tubular support arm shown in the figure as an example, assuming that the transverse width of the diamond tubular support arm is 20 mm, the wall thickness (i.e., the basic wall thickness) is 2.5 mm, the maximum transmission thickness of the diamond tubular support arm is within the range of 2.5 mm-17.5 mm of the transverse coordinate, and the maximum transmission thickness is 7.07 mm, which is approximately 2.5 mm of the basic wall thickness of the diamond tubular support arm. times, and the transmission thickness transition of the entire rhombus tubular support arm is uniform without obvious mutation. That is to say, when one of the radial center lines of the rhombus tubular support arm is perpendicular to the propagation direction of the X-ray, the distribution of the transmission thickness of the rhombus tubular support arm can be more uniform.

[0053] For further information, see Fig.10 The angle between two adjacent side walls of the rhombus-shaped tubular support arm can be 90 degrees, that is, the cross-section of the rhombus-shaped tubular support arm can be a special rhombus of a square, or the rhombus-shaped tubular support arm can be a square tubular support arm. However, when the rhombus-shaped tubular support arm is a square tubular support arm, any side wall of the square tubular support arm must also meet the condition that none of them is parallel to the propagation direction of the X-ray, that is, it cannot be used. Figure 1 Transmission method shown.

[0054] It is understandable that, in some embodiments, the angle between two adjacent side walls of the diamond-shaped tubular support arm may not be 90 degrees.

[0055] In one embodiment, please refer to Fig.12 , the polygonal tubular support arm is a trapezoidal tubular support arm, that is, the cross-section of the polygonal tubular support arm is a trapezoid.

[0056] Similar to the rhombus-shaped tubular support arm, the propagation direction of the X-ray can be perpendicular to any side wall of the trapezoidal tubular support arm, or can be oblique to any side wall of the trapezoidal tubular support arm. However, the propagation direction of the X-ray is not parallel to any side wall of the trapezoidal tubular support arm, that is, the X-ray penetrating from one end of any side wall of the trapezoidal tubular support arm cannot pass out from the other end opposite to the same side wall. Thus, it can be ensured that the maximum transmission thickness of the trapezoidal tubular support arm in the propagation direction of the X-ray is less than or equal to 4 times the basic wall thickness of the trapezoidal tubular support arm, or that the maximum transmission thickness of the trapezoidal tubular support arm in the propagation direction of the X-ray is less than or equal to 1 / 2 of the basic wall thickness of the trapezoidal tubular support arm. times.

[0057] In one embodiment, please refer to Fig.12 The two mutually parallel side walls of the trapezoidal tubular support arm are perpendicular to the propagation direction of the X-ray, thereby making the distribution of the transmission thickness of the trapezoidal tubular support arm more uniform.

[0058] It should be noted that the polygonal tubular support arms described in the embodiments of the present application are not limited to rhombus-shaped tubular support arms and trapezoidal tubular support arms. For example, in some embodiments, the cross-sectional shape of the polygonal tubular support arm may be a triangle, a non-rhombus parallelogram, or a pentagon, a hexagon, or a polygon with a side number greater than four. Some polygonal tubular support arms may also have one or two side walls parallel to the propagation direction of the X-rays, as long as the maximum transmission thickness of the polygonal tubular support arm in the propagation direction of the X-rays is less than or equal to 4 times the basic wall thickness of the polygonal tubular support arm, or the maximum transmission thickness of the polygonal tubular support arm in the propagation direction of the X-rays is less than or equal to Just times it.

[0059] In addition, the tubular support arm 20 is not limited to being a polygonal tubular support arm. For example, in one embodiment, see Fig.13 The tubular support arm 20 may be an elliptical tubular support arm, that is, the cross-section of the elliptical tubular support arm is elliptical.

[0060] The long axis of the elliptical tubular support arm in the radial direction may be perpendicular or oblique to the propagation direction of the X-ray. The long axis of the elliptical tubular support arm in the radial direction is also the long axis of the elliptical cross section, that is, the propagation direction of the X-ray is not parallel to the long axis of the elliptical tubular support arm in the radial direction, thereby ensuring that the maximum transmission thickness of the elliptical tubular support arm in the propagation direction of the X-ray is less than or equal to 4 times the basic wall thickness of the elliptical tubular support arm, or the maximum transmission thickness of the elliptical tubular support arm in the propagation direction of the X-ray is less than or equal to 1 / 2 of the basic wall thickness of the elliptical tubular support arm. times.

[0061] In one embodiment, please refer to Fig.11 The side wall of the tubular support arm 20 may also have a through hole 20a for X-rays to pass through, that is, a partial area on the side wall of the tubular support arm 20 may be set as a hollow structure, thereby reducing the transmission thickness of the tubular support arm 20 at the position of the through hole 20a.

[0062] The through hole 20a can penetrate the side wall of the tubular support arm 20 along the propagation direction of the X-ray, or penetrate the side wall of the tubular support arm 20 in a direction perpendicular to the propagation direction of the X-ray, or penetrate the side wall of the tubular support arm 20 in a direction oblique to the propagation direction of the X-ray. The through hole 20a can penetrate only the side wall on one side of the tubular support arm 20, or penetrate two opposite or adjacent side walls of the tubular support arm 20.

[0063] In one embodiment, please refer to Figure 5The table assembly 10 includes a seat plate 11, and a tubular support arm 20 is rotatably connected to the seat plate 11. The tubular support arm 20 is rotatably connected to the seat plate 11 to facilitate adjusting the angle of the tubular support arm 20, so as to facilitate medical staff to treat patients.

[0064] Another embodiment of the present application provides an orthopedic traction frame, see Fig.14 , including: a frame 30 and a tubular support arm 20, the tubular support arm 20 is arranged on the frame 30, and the tubular support arm 20 satisfies: the X-rays generated by the radiological imaging device can pass through the tubular support arm 20 along the propagation direction, and the maximum transmission thickness of the tubular support arm 20 in the propagation direction of the X-rays is less than or equal to 4 times the basic wall thickness of the tubular support arm 20, wherein the propagation direction of the X-rays is from the top of the tubular support arm 20 to the bottom of the tubular support arm 20, or, from the bottom of the tubular support arm to the top of the tubular support arm.

[0065] Specifically, the orthopedic traction frame can be used alone or in conjunction with an operating table. Similar to the operating table described above, the orthopedic traction frame can also be provided with a support member, which can be a support plate provided on the tubular support arm 20, such as a leg support plate for supporting the patient's legs, a pelvic support plate for supporting the patient's pelvis, etc. The support member can also be various traction devices provided on the tubular support arm 20.

[0066] The tubular support arm 20 on the orthopedic traction frame can be the tubular support arm 20 described in any embodiment of the present application, that is, the tubular support arm 20 set on the operating bed as described above can also be set on the orthopedic traction frame.

[0067] In one embodiment, the maximum transmission thickness of the tubular support arm 20 in the propagation direction of the X-ray is less than or equal to the base wall thickness of the tubular support arm 20. times.

[0068] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0069] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
