Technical Field
[0001] The utility model relates to the technical field of radiology, in particular to a perspective protection zone testing bracket for interventional radiology equipment. Background Art
[0002] Interventional radiology is based on diagnostic imaging and uses technologies such as catheters to provide non-surgical treatment of diseases under imaging monitoring. Interventional radiology equipment is required during interventional surgery, and test stents are required when interventional radiology equipment is working.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that when limiting the monitoring equipment, the above device is implemented by pressing down the sliding rod in the middle position through the monitoring equipment, and then blocking it with the outer sliding rod. Although this can achieve limiting, it also causes the operator to be unable to use the method of supporting the lower edge of the monitoring equipment when placing the monitoring equipment. Although the method of supporting both sides of the monitoring equipment can also be used to place the monitoring equipment, this method will significantly increase the physical consumption of the operator compared to the method of directly supporting the lower edge of the monitoring equipment. At the same time, it is also easy for the monitoring equipment to slip between the operator's hands. It is still not convenient enough in actual use.
[0005] Therefore, it is necessary to invent a test bracket for the fluoroscopic protection zone of interventional radiology equipment to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] The utility model provides Figure 1-2 The illustrated test bracket for the fluoroscopic protection zone of an interventional radiology device comprises a base plate 1, a lifting mechanism 2 is arranged on the top of the base plate 1, a bearing mechanism 3 is arranged inside the lifting mechanism 2, and four groups of limiting mechanisms 4 are arranged in a rectangular shape on the outside of the bearing mechanism 3.
[0021] like Figure 1As shown, the lifting mechanism 2 includes a U-shaped side plate 21, a top plate 22, a lifting plate 23, a guide rod 24, a first screw 25 and a driving motor 26, wherein two U-shaped side plates 21 are provided, and the two U-shaped side plates 21 are respectively fixedly provided on both sides of the top of the bottom plate 1, the top plate 22 is fixedly provided at the top of the two U-shaped side plates 21, the lifting plate 23 is slidably provided between the two U-shaped side plates 21 along the vertical direction, the guide rod 24 is slidably penetrated and provided on the left side of the top of the lifting plate 23 and is fixedly connected between the bottom plate 1 and the top plate 22, the first screw 25 penetrates the top plate 22 and the lifting plate 23 and is threadedly connected to the lifting plate 23, and the driving motor 26 is fixedly provided on the right side of the top of the top plate 22 and is transmission-connected to the first screw 25.
[0022] By setting the above structure, it is convenient to start the drive motor 26. After the drive motor 26 is started, it drives the first screw 25 to rotate continuously. When the first screw 25 rotates, it drives the lifting plate 23 guided by the guide rod 24 to continuously rise. When the lifting plate 23 rises, it drives the monitoring equipment to rise synchronously through the supporting mechanism 3, thereby completing the height adjustment of the monitoring equipment.
[0023] like Figure 2 As shown, the bearing mechanism 3 includes a sliding rod 31, a bearing plate 32, a lifting plate 33, a locking hole 34, a locking column 35, a reset spring 36 and a buffer spring 37, wherein the sliding rod 31 slides through the lifting plate 23, the bearing plate 32 and the lifting plate 33 are fixedly arranged at the top and bottom ends of the sliding rod 31 respectively, the locking hole 34 is opened on the side of the sliding rod 31, the locking column 35 is slidably nested inside the lifting plate 23, the reset spring 36 is fixedly connected between the lifting plate 23 and the locking column 35, and the buffer spring 37 is sleeved on the outside of the sliding rod 31 and fixedly connected to the lifting plate 23.
[0024] The above structure is provided so that the monitoring device can be taken by placing both hands at the lower edges of both sides of the monitoring device, and then the monitoring device is placed on the top of the carrying plate 32, and the monitoring device is pressed down. The force generated by the downward pressure acts on the locking column 35 through the carrying plate 32 and the sliding rod 31. At this time, the locking column 35 compresses the reset spring 36 and withdraws from the inner side of the locking hole 34. Then the sliding rod 31 drives the carrying plate 32 and the monitoring device to move downward, so that the monitoring device enters between the four limit plates 44, and then the limit is completed. When the monitoring device needs to be removed later, the lifting plate 33 is pushed upward. When the lifting plate 33 moves up, the monitoring device is driven to move up synchronously through the sliding rod 31 and the carrying plate 32. When the locking hole 34 and the locking column 35 are in line, the compressed reset spring 36 pushes the locking column 35 into the inner side of the locking hole 34 for locking. Compared with the same type of device in the prior art, the operator can place and remove the monitoring device more conveniently, and at the same time, the limit of monitoring devices of different specifications can be achieved, and the actual use effect is better.

[0026] By setting the above structure, when the specifications of the monitoring equipment change, the threaded sleeve 42 is manually rotated. When the threaded sleeve 42 rotates, it drives the second screw 43 to move inside it. When the second screw 43 moves, it drives the limit plate 44 to move synchronously, thereby completing the adjustment to achieve the limit of monitoring equipment with different specifications.
[0027] Working principle of this utility model:
[0028] During actual use, the monitoring device is picked up by placing both hands at the lower edges of both sides of the monitoring device, and then the monitoring device is placed on the top of the carrying plate 32, and the monitoring device is pressed down. The force generated by the downward pressure acts on the locking column 35 through the carrying plate 32 and the sliding rod 31. At this time, the locking column 35 compresses the reset spring 36 and withdraws from the inner side of the locking hole 34. Then the sliding rod 31 drives the carrying plate 32 and the monitoring device to move downward, so that the monitoring device enters between the four limit plates 44, and then the limit is completed;
[0029] The driving motor 26 is started. After the driving motor 26 is started, the first screw 25 is driven to rotate continuously. When the first screw 25 rotates, the lifting plate 23 guided by the guide rod 24 is driven to rise continuously. When the lifting plate 23 rises, the monitoring device is driven to rise synchronously through the bearing mechanism 3, thereby completing the height adjustment of the monitoring device.
[0030] When the monitoring device needs to be removed later, the lifting plate 33 is pushed upward. When the lifting plate 33 moves upward, the monitoring device is driven to move upward synchronously through the sliding rod 31 and the bearing plate 32. When the locking hole 34 and the locking column 35 are in line, the compressed return spring 36 pushes the locking column 35 into the inner side of the locking hole 34 to lock it.
[0031] When the specifications of the monitoring equipment change, the threaded sleeve 42 is rotated manually. When the threaded sleeve 42 rotates, it drives the second screw 43 to move inside it. When the second screw 43 moves, it drives the limit plate 44 to move synchronously, thereby completing the adjustment to achieve the limit for monitoring equipment of different specifications.
[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
