Description

Technical Field

[0001] This utility model relates to the field of X-ray machine structure technology, and in particular to a C-arm structure for an X-ray machine. Background Technology

[0002] A C-arm, also known as a C-type arm or C-arm X-ray machine, is a device with a C-shaped frame. This device mainly consists of an X-ray tube that generates X-rays, an image intensifier and CCD camera that acquire images, and an image processing workstation. The main function of the C-arm is to perform fluoroscopy and spot imaging in various surgeries. Compared with other X-ray equipment (such as U-arms and G-arms), it has a unique frame shape and applicable scenarios.

[0003] The applicant's research revealed that in the design of C-arms in certain medical engineering fields, counterweights may be used for balancing and calibration to increase the stability and accuracy of the equipment. Generally, the position of the counterweight on the C-arm is designed to increase the stability and accuracy of the equipment. In many cases, to balance the weight of the equipment or improve the accuracy of calibration, the counterweight may be installed below the radiation source. However, traditional screw installation is cumbersome, and disassembly and assembly are laborious, making quick installation and disassembly impossible. Secondly, the radiation source and the counterweight are mostly mounted together on the support plate at the side end of the arm, and the support plate is also fixed to the arm with bolts. The load is heavy, which can easily lead to high brightness at the connection between the mounting plate of the radiation source and the counterweight at the side end of the arm, and can easily cause damage and loosening of the connection position.

[0004] Therefore, the applicant proposed a C-arm structure for an X-ray machine to solve the problem. Utility Model Content

[0005] This invention provides a C-arm structure for an X-ray machine, which solves the problems mentioned in the background.

[0006] To solve the above-mentioned technical problems, this utility model provides a C-arm structure for an X-ray machine, including a boom. An imager is installed at the upper end of the boom, and an assembly plate is fixed at the lower end. A support plate is integrally installed on one side of the assembly plate. An X-ray source is installed at the top of the support plate, and a counterweight is attached to the bottom of the support plate. An insert plate at the top of the counterweight passes through an opening in the support plate. An assembly assembly is connected between the insert plate and the support plate to limit the counterweight from falling. A reinforcing support assembly is connected between the assembly plate and the boom to strengthen the connection between the assembly plate and the boom.

[0007] Preferably, the assembly includes an arc-shaped slide rail fixed to the top of the support plate and the insert plate, an arc-shaped slide plate sliding in the inner slide rail of the arc-shaped slide rail, an arc-shaped block fixed to the inner side of the arc-shaped slide plate, and a lever fixed to the outer side of the arc-shaped slide plate, the lever passing through a long opening on the outer side of the arc-shaped slide rail.

[0008] Preferably, the counterweight consists of a hollow block and a sealing plate. The top of the hollow block is designed to be open, and the open surface is sealed to the sealing plate by screws. An insert plate is installed on the top of the sealing plate and fits against the bottom of the support plate.

[0009] Preferably, a mating block is fixed to the side wall of the assembly plate. The mating block is inserted into the inner cavity from the side opening of the boom and fits in place. The protrusions on both sides of the mating block fit in place with the two ends inside the boom. The boom is fixed to the protrusions of the mating block by screws inserted from the outside.

[0010] Preferably, the reinforced support assembly includes a reinforcing rod extending from the outer side of the boom, the reinforcing rod being in contact with the curved surfaces of two reinforcing plates, the reinforcing plates being in contact with the outer wall of the boom, i.e., this part is an arc-shaped curved design, and the lower end face of the curved part of the reinforcing plate is engaged in the recess of the locking block, the locking block being fixedly connected to the reinforcing rod by two bolts.

[0011] Preferably, a reinforcing block is installed on the side wall of the assembly plate below the mating block, and the reinforcing block is fixedly connected to the reinforcing rod by bolts.

[0012] Preferably, a dust cover can be fitted onto the upper end of the support plate, and a U-shaped frame is provided on the outer side of the opening on one side of the dust cover, with the U-shaped frame fitting against the outer wall of the assembly plate.

[0013] Compared with related technologies, the C-arm structure for an X-ray machine provided by this utility model has the following beneficial effects:

[0014] 1. In this utility model, the assembly component achieves rapid installation and fixation of the counterweight block through the innovative arc-shaped slide and arc-shaped sliding plate design. Users only need to simply move the lever to make the arc-shaped block simultaneously fit with the surface of the insert plate or the support plate to complete the fixation. This process does not require the use of screws or other fasteners, which greatly simplifies the installation steps and improves the installation efficiency.

[0015] 2. The design of the reinforced support component in this utility model effectively enhances the connection strength between the assembly plate and the boom by introducing structures such as reinforcing rods, reinforcing plates, and locking blocks, thereby improving the stability of the overall structure. Especially when the C-shaped boom bears the weight of the radiation source and the counterweight for a long time, the reinforced support component can effectively distribute the load and reduce the risk of damage and loosening at the connection points, thus ensuring the long-term stable operation of the equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Depend on Figures 1-8The present invention includes a boom 1, an imager 11 mounted on the upper end of the boom 1, and an assembly plate 12 fixed to the lower end. A support plate 13 is integrally mounted on one side of the assembly plate 12. An X-ray source 14 is mounted on the top of the support plate 13. A counterweight 2 is attached to the bottom of the support plate 13. An insert plate 23 at the top of the counterweight 2 passes through the opening of the support plate 13, and the outer wall of the insert plate 23 is attached to the inner wall of the opening of the support plate 13. An assembly assembly 3 is connected between the insert plate 23 and the support plate 13 to limit the counterweight 2 from falling. A reinforcing support assembly 4 is connected between the assembly plate 12 and the boom 1 to strengthen the connection between the assembly plate 12 and the boom 1.

[0028] Assembly component 3 includes an arc-shaped slide rail 31 fixed to the top of support plate 13 and insert plate 23. An arc-shaped slide plate 33 slides in the inner slide rail of the arc-shaped slide rail 31. An arc-shaped block 32 is fixed inside the arc-shaped slide plate 33. The arc-shaped block 32 moves against the surface of insert plate 23 or support plate 13. An actuating rod 34 is fixed outside the arc-shaped slide plate 33. The actuating rod 34 passes through the long opening outside the arc-shaped slide rail 31.

[0029] Through the design of assembly component 3, when installing counterweight 2, counterweight 2 is attached to the bottom of support plate 13. At this time, insert plate 23 passes through the opening of support plate 13, and the surfaces of the two are aligned. At this time, the position of insert plate 23 corresponds to the position of arc-shaped sliding plate 33 on support plate 13. Figure 6 As shown at point a, the thumb and forefinger simultaneously move the two levers 34, causing the two curved blocks 32 to rotate 90 degrees, and their curved sliding plates 33 also rotate 90 degrees. At this time, the levers 34 rotate to the other end of the long opening and fit together. Simultaneously, the bottom surfaces of the two curved blocks 32 are in contact with the surfaces of the insert plate 23 and the support plate 13, and the two curved sliding plates 33 also move into each other's curved slide rails 31 during sliding, that is, one curved sliding plate 33 is in both curved slide rails 31, as shown. Figure 6 As shown at point b, or see details. Figure 7 At this point, assembly component 3 fixes the support plate 13 and the insert plate 23 together, ensuring that the counterweight 2 cannot fall off, thus completing the installation. Note that the arc-shaped sliding plate 33 has a certain rotational resistance, so the connection is relatively firm. A certain amount of force is required when moving the lever 34. It is more efficient and faster than screw installation, but it should be noted that a visual inspection is required before each use.

[0030] The counterweight 2 consists of a hollow block 22 and a sealing plate 21. The top of the hollow block 22 is designed to be open, and the open surface is sealed to the sealing plate 21 by screws. The top of the sealing plate 21 is fitted with an insert plate 23 and is attached to the bottom of the support plate 13.

[0031] Furthermore, the aforementioned cavity design allows the counterweight 2 to be adapted to the size of the equipment, and the cavity design facilitates manufacturing and production, making it very practical.

[0032] See details Figures 1-5 The assembly plate 12 has a mating block 15 fixed to its side wall. The mating block 15 is inserted into the inner cavity from the side opening of the boom 1 and fits in place. The protrusions on both sides of the mating block 15 fit in place with the inner ends of the boom 1. The boom 1 is fixed to the protrusions of the mating block 15 by screws inserted from the outside. The reinforcement support assembly 4 includes a reinforcement rod 41 that extends from the outer side of the boom 1. The reinforcement rod 41 fits in place with the curved surfaces of the two reinforcement plates 42. The reinforcement plates 42 fit in place with the outer wall of the boom 1. That is, this part is an arc-shaped curved design. In addition, the lower end face of the curved part of the reinforcement plate 42 is engaged in the recess of the locking block 43. The locking block 43 is fixedly connected to the reinforcement rod 41 by two bolts. The assembly plate 12 has a reinforcement block 44 installed below the mating block 15 on its side wall. The reinforcement block 44 is fixedly connected to the reinforcement rod 41 by bolts.

[0033] By strengthening the design of the support component 4, and optimizing the connection strength, when installing the assembly plate 12, the assembly plate 12 is fitted to the boom 1, so that the mating block 15 is inserted into the inner cavity from the side opening of the boom 1 and fitted. Then, the initial installation is achieved by fixing with screws. Next, the reinforcement installation is carried out by fitting the two reinforcement plates 42 to the outer wall of the boom 1. Then, the reinforcement rod 41 is passed through from the outer extension surface of the boom 1 (this is the existing design, because the boom 1 needs to rotate 180 degrees in actual application, so the extension surface is used as a slide, which will not be described in detail here) and fitted with the curved surface of the two reinforcement plates 42 to lock them in place. Then, the reinforcement plates 42 are locked by the locking block 43 and connected to the reinforcement rod 41 by bolts. Finally, two bolts are passed through the reinforcement rod 41, as shown in the figure. Figure 4 As shown at point c, it docks with the reinforcing block 44 and then connects to the assembly plate 12, thus effectively improving the support strength of the support plate 13. The support plate 13 is subjected to downward force through the X-ray source 14 and the counterweight 2. The reinforcing plate 42 is attached to the bottom surface of the boom 1 to further improve the support force and enhance the connection stability.

[0034] See details Figure 9 A dust cover 5 can be fitted onto the upper end of the support plate 13. A U-shaped frame is provided on the outer side of the opening on one side of the dust cover 5, and the U-shaped frame is attached to the outer wall of the assembly plate 12.

[0035] The dust cover 5 is designed to cover the dust cover when not in use, thus effectively preventing dust. The inner wall of the dust cover 5 can be equipped with a support plate that rests on the support plate 13. The U-shaped frame enhances the fit and strengthens the dustproof effect.

[0036] Working principle: The installation process is as follows: First, when installing the assembly plate 12, it is placed against the boom 1, so that the mating block 15 is inserted into the inner cavity from the side opening of the boom 1 and fits in place. Initial installation is achieved by fixing with screws. Next, the two reinforcing plates 42 are attached to the outer wall of the boom 1. The reinforcing rod 41 extends from the outer side of the boom 1 and fits against the inner curved surface of the two reinforcing plates 42, locking them in place. Then, the reinforcing plates 42 are secured by locking blocks 43 and connected to the reinforcing rod 41 by bolts. Finally, two bolts pass through the reinforcing rod 41 and mate with the reinforcing block 44, which is then connected to the assembly plate 12. Then, the X-ray source 14 is first installed on the assembly plate 12, and then the counterweight 2 is... The insert plate 23 is attached to the bottom of the support plate 13. At this time, the insert plate 23 passes through the opening of the support plate 13, and the positions of the insert plate 23 and the arc-shaped sliding plate 33 on the support plate 13 correspond. Then, the thumb and forefinger simultaneously move the two levers 34, causing the two arc blocks 32 to rotate 90 degrees, and the arc-shaped sliding plates 33 of both also rotate 90 degrees. At this time, the levers 34 rotate to the other end of the long opening and are attached. At the same time, the bottom surfaces of the two arc blocks 32 are in contact with the surfaces of the insert plate 23 and the support plate 13, and the two arc-shaped sliding plates 33 also move into the arc-shaped slide 31 of each other when sliding. The counterweight 2 can not fall off, thus completing the installation. When working, it can be used in conjunction with the imager 11 and the X-ray source 14.
