Description

Technical Field

[0001] The present application relates to the technical field of scanner auxiliary equipment, and in particular to a CBCT diagnostic bed. Background Art

[0002] A CBCT (Cone Beam Computed Tomography) scanner is a cone-beam computerized tomography (CCT) scanner that uses three-dimensional imaging technology to provide detailed and accurate image data. The diagnostic couch is a crucial component of the scanner. During medical diagnostics, it not only provides a comfortable and stable examination environment for patients but also ensures a smooth scanning process.

[0003] During surgery, there is a need for accurate imaging of the surgical site or related areas, leading to the need for in-room scanning and testing. Therefore, the operating room is equipped with a CBCT scanner, diagnostic table, and operating table, which places high demands on the operating room's space.

[0039] See also Figures 1 to 6 This application provides a CBCT diagnostic bed that can be used in conjunction with CBCT to meet clinical examination needs and can also meet the different body posture requirements of surgical treatment. Specifically including:

[0040] The columns 4 are arranged vertically, and the bed board 1 is set on the top of the columns 4. The columns 4 include a first support column 16 and a second support column 17. The bottom of the first support column 16 is downwardly sleeved on the upper part of the second support column 17 to adjust the extension length of the first support column, thereby realizing the adjustment of the bed board height;

[0041] A base 7 is provided at the bottom of the column 4. The base 7 includes a screw rod 8 mechanism provided therein. The screw rod 8 mechanism is in transmission connection with the bottom of the column 4. The screw rod 8 mechanism is used to adjust the position of the column 4 on the horizontal plane.

[0042] It should be noted that the length direction of the base 7 is the first direction, and the width direction of the base 7 is the second direction.

[0043] Angle adjustment mechanism, connected between the bed board 1 and the column 4; including a connection frame 2 provided on the top of the column 4, such as Figure 4 As shown, a first connecting shaft 11 and a second connecting shaft 12 are disposed within the connecting frame 2. The first connecting shaft 11 and the second connecting shaft 12 are disposed parallel to each other and arranged along a first direction. Both ends of the first connecting shaft 11 or the second connecting shaft 12 are rotatably connected to the front and rear sides of the connecting frame 2. The first connecting shaft 11 is disposed in the middle of the connecting frame 2, and the second connecting shaft 12 is disposed to the left or right side of the first connecting shaft 11.

[0044] It should be noted that a connection component 3 is provided on the connection frame 2 , and is fixedly connected to the bottom of the bed board 1 through the connection component 3 .

[0045] like Figure 4 As shown, the front end of the first connecting shaft 11 extends outward from the connecting frame 2, and a first connecting seat 13 is configured at the front end; Figure 5 As shown, a first connecting lug 18 is provided on the front side of the column 4, and the first connecting seat 13 is connected to the first connecting lug 18 via a first push rod 14. By controlling the extension of the first push rod 14, the connecting frame 2 can be adjusted along the axis direction of the first connecting shaft 11.

[0046] like Figure 6 As shown, a third connecting seat 21 is provided on the top of the column 4, and the middle part of the first connecting shaft 11 is hinged to the third connecting seat 21. Through the extension and retraction of the first push rod 14, the connecting frame 2 is adjusted with the third connecting seat 21 as the fulcrum and the inclination angle in the first direction, thereby adjusting the angle of the bed board 1 in the first direction.

A guide rail 10 is provided on the top of the support frame and arranged along the length direction of the base 7. The guide rail 10 is used to connect with the bottom of the column 4 and guide the column 4 during its movement so that the column 4 can complete the adjustment of its horizontal position along the guide rail 10.

[0054] In one practicable manner, Figure 2 As shown, a sliding plate is sleeved under the column 4. A through slot is provided at the center of the sliding plate. The column 4 is inserted into the through slot so that the sliding plate is sleeved on the outside of the column 4. A locking slot is provided on the bottom surface of the sliding plate. The locking slot is fixed on the guide rail 10 to limit the sliding plate. By inserting the column 4 into the through slot, the sliding plate slides along the guide rail 10, controlling the column 4 to slide in a limited position.

[0055] In one practicable manner, a plurality of rotating gears are provided on the inner side of the slot, and a rack is provided on the outer side of the guide rail 10 , and the plurality of rotating gears are meshed with the rack to enable the sliding plate to move along the guide rail 10 .

[0057] In one practicable embodiment, a third push rod is provided between the first support column 16 and the second support column. The third push rod is an electric push rod or an electro-hydraulic push rod, which has the advantages of simple structure and low cost.

[0058] In summary, the present application can meet the requirements of various body positions of the CBCT scanner, and can also meet the use requirements of different body positions in surgical treatment. Moreover, the CBCT diagnostic bed provided by the present application can replace both conventional operating beds and conventional diagnostic beds, saving installation space. By setting the first push rod 14 and the second push rod 15, the inclination angle of the bed board 1 in two directions can be adjusted. By setting the third push rod, the height of the bed board 1 can be adjusted. By setting the screw rod 8 mechanism, the position of the bed board 1 in the longitudinal direction can be adjusted so that the bed board 1 can be moved into the CBCT scanner for scanning and detection.
