Description

Technical Field

[0001] The utility model relates to a pull - out scanning frame of a static CT, and also relates to a static CT device including the pull - out scanning frame, belonging to the technical field of medical devices. Background Art

[0002] CT (Computed Tomography) is short for Computed Tomography. It uses precisely collimated X - ray beams, γ - rays, ultrasonic waves, etc., together with highly sensitive CT detectors to perform cross - sectional scanning around a certain part of the human body. It has the characteristics of fast scanning time and clear images, and can be used for the examination of various diseases. At present, tens of thousands of CT devices of various models have been installed in hospitals at all levels across the country. CT examinations have been rapidly popularized nationwide and have become an indispensable device in medical diagnosis. However, existing CT devices are generally relatively expensive, so special care is required in use, maintenance, and servicing.

[0003] In the Chinese utility model with the patent number ZL 201921086781.5, a CT control panel convenient for maintenance is disclosed. It uses a pivotal structure at the top of the outer cover and the frame, enabling the outer cover to rotate and rise to a position of 90°. As shown in Figure 7, maintenance personnel can operate the CT device through the maintenance buttons on the back of the control panel.

[0004] A typical CT device consists of a scanning frame, a scanning bed, an operation console, and some auxiliary systems. When maintaining and servicing a CT device, it is necessary to open the outer cover of the scanning frame. Usually, it is manually disassembled and a relatively large space is required to place the removed outer cover. Since the outer cover itself is heavy and large in volume, two to three people are usually required to operate simultaneously during the disassembly process. And there is a scanning bed set up closely in front of the scanning frame. Therefore, when disassembling and reinstalling the outer cover, it is easy to collide with the scanning bed. However, since the entire outer cover rotates around the top pivotal structure, there cannot be parts such as a scanning bed in the area swept by the outer cover, and the opened outer cover also requires a separate support structure to prevent the outer cover from automatically falling under the action of gravity, resulting in personal injury.

[0039] As Figure 1 shown, the static CT equipment provided by the embodiment of the present invention includes a pull-out scanning frame 1 and a scanning bed 2. The scanning bed 2 is arranged at a position in front of the pull-out scanning frame 1 and extends along a predetermined direction ( Figure 1 shown as the Z direction in the figure). When the CT equipment scans, the scanning bed 2 enters the circular hollow area 111 of the pull-out scanning frame 1 along the Z direction. In the present invention, the Z direction refers to the direction in which the scanning bed 2 moves and is also the length direction of the patient's body when lying flat on the scanning bed. When performing a CT scan, the body is scanned along the Z direction. For the convenience of description, the direction towards the scanning bed 2 with the pull-out scanning frame 1 as the reference is called the front, and the opposite is the rear. Those skilled in the art can understand that the scanning bed 2 can also extend along other predetermined directions (X direction or Y direction), and will not be exemplified one by one here.

[0040] As Figure 2 shown, the pull-out scanning frame 1 provided by the embodiment of the present invention includes a scanning frame 11, a translation mechanism 12, a front cover 13 and a rear cover 14. The translation mechanism 12 is installed on the scanning frame 11, and the front cover 13 and the rear cover 14 are respectively movably installed in front of and behind the scanning frame 11 through the translation mechanism 12. When the static CT equipment of the embodiment of the present invention is under maintenance and repair, it is necessary to open the front cover 13 and / or the rear cover 14 by pulling (as Figure 2Only the front cover 13 is opened, enabling maintenance workers to enter the interior of the scanning frame 11 for maintenance work. During the process of opening and closing the front cover 13 and / or the rear cover 14, the movement is guided by the translation mechanism 12, and neither the front cover 13 nor the rear cover 14 will separate from the scanning frame 11. Moreover, due to the corresponding avoidance structure provided on the front cover 13 (detailed description below), it will not touch the scanning bed 2, which is suitable for single-person maintenance, improving the maintenance efficiency, reducing labor costs, and avoiding personal injuries or equipment damage.

[0041] As Figure 1 shown, in this embodiment, the scanning frame 11 is a circular hollow frame, and a circular hollow area 111 is formed at the center of the scanning frame 11. Among them, an X-ray tube and a detector (not shown in the figure) are provided on the scanning frame 11, which are the most important components for scanning in a static CT device.

[0042] As Figure 2 shown, in this embodiment, the translation mechanism 12 is provided on the scanning frame 11 and includes a first translation part 121 and a second translation part 122. Among them, the first translation part 121 can reciprocate in the direction towards the front of the scanning frame 11. The front cover 13 is provided in front of the scanning frame 11 and is connected to the first translation part 121 to approach or move away from the scanning frame 11 as the first translation part 121 moves. The second translation part 122 can reciprocate in the direction towards the rear of the scanning frame 11. The rear cover 14 is provided behind the scanning frame 11 and is connected to the second translation part 122 to approach or move away from the scanning frame 11 as the second translation part 122 moves. And, as Figure 3 shown, a first circular hole 131 corresponding to the circular hollow area 111 is formed at the center of the front cover 13, and a second circular hole 141 corresponding to the circular hollow area 111 is formed at the center of the rear cover 14, for the part of the patient to be examined to be sent into this area.

[0043] As Figure 3 shown, in the above embodiment, the first translation part 121 includes a guide rail fixing member 1211 and a first guide rail 1212. Among them, the guide rail fixing member 1211 is arranged on the outer wall of the scanning frame 11 along the direction parallel to the central axis of the scanning frame 11 (i.e., the Z direction). In this embodiment, the guide rail fixing member 1211 is strip-shaped and is used to provide an installation basis for the first guide rail 1212. The first guide rail 1212 is arranged on one side of the guide rail fixing member 1211, and the first end (i.e., Figure 3 the left end in Figure 3 ) of the first guide rail 1212 is fixedly connected to the guide rail fixing member 1211, and the second end (i.e.,

[0044] As Figure 3 shown, in the above embodiment, the second translation part 122 includes a guide rail fixing part 1221 and a second guide rail 1222. Among them, the guide rail fixing part 1221 is arranged on the outer wall of the scanning frame 11 along the direction parallel to the central axis of the scanning frame 11 (i.e., the Z direction). In this embodiment, the guide rail fixing part 1221 is strip-shaped and is used to provide an installation basis for the second guide rail 1222. The second guide rail 1222 is arranged on one side of the guide rail fixing part 1221, and the first end of the second guide rail 1222 (i.e., Figure 3 the right end in Figure 3 here) is fixedly connected to the guide rail fixing part 1221, and the second end of the second guide rail 1222 (i.e.,

[0045] the left end in

[0046] As Figure 3 shown, in the above embodiment, preferably, the first guide rail 1212 and the second guide rail 1222 share a guide rail fixing part (i.e., the guide rail fixing part 1211 and the guide rail fixing part 1221 are the same component), and the first guide rail 1212 and the second guide rail 1222 are respectively arranged on opposite sides of the guide rail fixing part. Thus, the guide rail fixing part, the first guide rail 1212 and the second guide rail 1222 together form a guide rail assembly. Therefore, by arranging a plurality of guide rail assemblies on the outer wall of the scanning frame 11 and the plurality of guide rail assemblies being parallel to each other, the front cover 13 is respectively connected to the first guide rails 1212 of the plurality of guide rail assemblies, and the rear cover 14 is respectively connected to the second guide rails 1222 of the plurality of guide rail assemblies. Thus, on the one hand, the connection stability of the front cover 13 and the rear cover 14 is improved, and on the other hand, through the combined action of a plurality of guide rails, the stability of translation is ensured.

[0047] As Figure 3As shown in the above embodiments, an avoidance hole 132 is formed in the front cover 13 for avoiding the scanning bed 2. In addition, in this embodiment, the shape of the avoidance hole 132 matches the shape of the area 21 to be avoided on the scanning bed 2 (the rectangular bed frame at the bottom in this embodiment). On the one hand, it plays a role in avoiding the scanning bed, and on the other hand, it can also limit the movement of the front cover 13 through the mutual cooperation of the two, so as to prevent the front cover 13 from flipping and improve the safety of use.

[0048] In the above embodiments, preferably, a first engaging portion is provided on the front cover 13, and a second engaging portion is provided on the scanning frame 11. The first engaging portion and the second engaging portion are engaged or separated to limit or release the relative position between the front cover 13 and the scanning frame 11. Similarly, a third engaging portion is provided on the rear cover 14, and a fourth engaging portion is provided on the scanning frame 11. The third engaging portion and the fourth engaging portion are engaged or separated to limit or release the relative position between the rear cover 14 and the scanning frame 11. Thus, when it is not necessary to open the front cover 13 or the rear cover 14, the front cover 13 or the rear cover 14 can be limited and fixed by engaging, so as to prevent the front cover 13 or the rear cover 14 from sliding relative to the scanning frame 11.

[0049] In addition, in the above embodiments, preferably, rollers are provided at the bottoms of the front cover 13 and the rear cover 14, and the rollers are in contact with the working surface. Thus, through the rolling cooperation between the rollers and the working surface, the convenience of pushing and pulling the front cover 13 and the rear cover 14 can be improved.

[0050] In summary, the pull-out type scanning frame provided by the present utility model and the static CT device including the scanning frame have the following beneficial effects:

[0051] (1) By providing a translation mechanism 12 on the scanning frame 11, the front cover 13 and the rear cover 14 can be movably installed in front of and behind the scanning frame 11 respectively through the translation mechanism 12, so that the cover can be quickly and easily opened and closed through the pull-out type design, providing great convenience for subsequent internal maintenance and component replacement.

[0052] (2) The pull-out type design simplifies the complex operation of the traditional flip type cover, saving time and effort. Moreover, the overall structure is more concise, reducing the number of moving parts and potential failure points, not only reducing the manufacturing cost, but also improving the stability and reliability of the device.

[0053] (3) It is only necessary to provide necessary avoidance holes on the front cover 13, without opening large avoidance hole positions on the device, maintaining the overall aesthetics of the device.

[0054] It should be noted that the above-mentioned multiple embodiments are only examples, and the technical solutions of each embodiment can be combined, all within the protection scope of the present utility model.

[0055] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.
