Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a C-arm X-ray machine. Background Technology

[0002] Mobile C-arm X-ray machines are mainly used in orthopedics for procedures such as bone setting, reduction, nailing, some interventional treatments, some angiography, and local radiography. When the equipment is working, X-rays generated by the combined X-ray source pass through the human body and hit the flat panel detector, which converts the X-rays into image data to generate an image.

[0003] The C-arm is one of its main structural components. A combined X-ray source and a flat-panel detector are mounted at each end of the C-arm. The C-arm and its core components can rotate freely around its center. The operator needs to adjust the position in real time according to different usage requirements, fixing it in a suitable position for X-ray imaging. The sliding motion of the C-arm is one of the most frequently used functions for medical personnel operating the equipment. Traditionally, the C-arm is manually pulled around its center and then manually locked, which is cumbersome, laborious, and inefficient. Furthermore, medical personnel need one hand to operate the sliding motion and the other to lock it, requiring two hands and increasing the difficulty of operation. Additionally, the C-arm must be kept stable during the sliding adjustment process. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a C-arm X-ray machine that is easy to operate and ensures stability during adjustment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a C-arm X-ray machine, comprising a body, a supporting inclined arm, and a C-arm. The C-arm is mounted on the body via the supporting inclined arm. A flat panel detector is provided at the upper end of the C-arm, and an X-ray source is provided at the lower end of the C-arm. The X-ray source and the flat panel detector are arranged opposite to each other. A sliding groove is provided along the outer arc surface of the C-arm. A driving component for driving the C-arm to slide is provided on the supporting inclined arm. Supporting sliding components are provided on both sides of the supporting surface of the supporting inclined arm, and the supporting sliding components are rotatably mounted in the sliding groove.

[0006] Preferably, the supporting sliding assembly includes a sliding wheel and a supporting bearing. The sliding wheel and the supporting bearing are rotatably mounted on both sides of the supporting inclined arm. The axis of rotation of the sliding wheel is set perpendicular to the axis of rotation of the supporting bearing. The sliding wheels on both sides are supported and rolled on the two side walls of the slide groove, and the supporting bearing is supported and rolled on the bottom surface of the slide groove.

[0007] Preferably, two sliding wheels and two support bearings are provided on both sides of the support arm.

[0008] Preferably, the drive assembly includes a timing belt, a timing pulley, and a rotational power assembly. The timing pulley is connected to the rotational power assembly, the timing belt is wound around the timing pulley, and both ends of the timing belt are fixedly connected to both ends of the C-arm.

[0009] Preferably, two support wheels are provided on the side of the synchronous pulley near the C-arm. The support wheels are rotatably mounted on the support inclined arm. The synchronous belt passes around the synchronous pulley and passes through the inside of the two support wheels and wraps around the support wheels.

[0010] Preferably, the rotational power assembly includes a motor and a transmission assembly, with a speed reducer provided between the motor and the transmission assembly, and a synchronous pulley connected to the output end of the transmission assembly.

[0011] Preferably, the transmission assembly includes a drive gear and a transmission gear. The drive gear is connected to the output end of the reducer, the transmission gear and the drive gear mesh, and the synchronous pulley and the transmission gear are coaxially arranged.

[0012] Preferably, the cross-section of the slide groove is convex, and the sliding support assembly is supported and slidably disposed in the grooves on both sides of the slide groove.

[0013] Preferably, a handle is provided on one side of the C-arm.

[0014] Preferably, the operation screen is rotatably mounted on the machine body.

[0015] Compared with existing technologies, the above technical solution has the following beneficial effects:

[0016] 1. A support sliding assembly is provided between the support inclined arm and the C-shaped arm of this utility model. The support sliding assembly is supported and slidably installed in the slide groove of the C-shaped arm to ensure that the C-shaped arm remains stable during sliding adjustment and facilitates operation by medical staff.

[0017] 2. The adjustment of the C-arm in this utility model is replaced by electric motion instead of the original manual motion, making the operation simpler. The original structure required one hand to operate the C-ring and the other hand to operate the brake, which required two hands to operate. This utility model only requires one hand to operate, making it more convenient and flexible.

[0018] 3. It adopts a gear and synchronous belt drive structure, which is stable and reliable. The motor has a built-in brake structure, eliminating the need for the original brake operation. The electric operation can achieve one-step operation. After one operation, it will automatically run to the designated position, which greatly simplifies the operation process and improves work efficiency. Attached Figure Description

[0025] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0026] like Figures 1-2 As shown, this utility model discloses a C-arm X-ray machine, including a body 1, a supporting inclined arm 8, and a C-arm 4. An operation screen 3 is mounted on the body 1. The C-arm 4 is adjustablely mounted on the body 1 via the supporting inclined arm 8. A flat panel detector 5 is mounted at the upper end of the C-arm 4, and an X-ray source 6 is mounted at the lower end of the C-arm 4. The X-ray source 6 and the flat panel detector 5 are positioned opposite each other. When the equipment is working, the X-ray source 6 generates X-rays that pass through the human body and strike the flat panel detector 5. The flat panel detector 5 converts the X-rays into image data to generate an image. A sliding groove 22 is formed along the outer arc surface of the C-arm 4. A driving component for sliding the C-arm 4 is mounted on the supporting inclined arm 8. The driving component adjusts the position of the C-arm 4, thereby adjusting the position to be examined. Supporting sliding components are mounted on both sides of the supporting surface of the supporting inclined arm 8. The supporting sliding components are rolled within the sliding groove 22 to ensure the stability of the C-arm 4 during sliding adjustment, facilitating operation by medical personnel.

[0027] like Figure 3As shown, the drive assembly in this embodiment includes a synchronous belt 10, a synchronous pulley 20, and a rotational power assembly 13. The two ends of the synchronous belt 10 are fixedly connected to the two ends of the C-arm 4, and the synchronous pulley 20 is connected to the rotational power assembly 13. The rotational power assembly 13 drives the synchronous pulley 20 to rotate, and the synchronous belt 10 is wound around the synchronous pulley 20, thereby causing the synchronous belt 10 to drive the C-arm 4 to rotate, allowing the C-arm 4 to rotate arbitrarily around the center, thereby adjusting the position of the two ends of the C-arm 4 for irradiation examination. Medical personnel need to adjust the position in real time according to different usage needs, and fix it at a suitable position to perform X-ray imaging. The adjustment of the C-arm 4 is replaced by electric movement instead of the original manual movement, making the operation simpler and more flexible.

[0028] Two support wheels are provided on the side of the synchronous pulley 20 near the C-arm 4. The two support wheels are the upper support wheel 12 and the lower support wheel 11. The support wheels are rotatably mounted on the support inclined arm 8. The synchronous belt 10 passes through the inside of the two support wheels after passing around the synchronous pulley 20. The upper end of the synchronous belt 10 is wrapped around the upper support wheel 12 and connected to the upper end of the C-arm 4. The lower end of the synchronous belt 10 is wrapped around the lower support wheel 11 and connected to the lower end of the C-arm 4.

[0029] like Figure 4 As shown, when adjusting the C-arm 4, the supporting sliding assembly is supported and slidably installed in the slide groove 22. The supporting sliding assembly includes a sliding wheel 14 and a supporting bearing 15. The sliding wheel 14 and the supporting bearing 15 are rotatably installed on both sides of the supporting inclined arm 8. In this embodiment, two sliding wheels 14 and two supporting bearings 15 are provided on both sides of the supporting inclined arm 8. The rotation axis of the sliding wheel 14 is perpendicular to the rotation axis of the supporting bearing 15. The sliding wheels 14 on both sides are supported and rolled on the two side walls of the slide groove 22, and the supporting bearings 15 are supported and rolled on the bottom surface of the slide groove 22. The cross-section of the slide groove 22 is convex. The sliding wheels 14 and the supporting bearings 15 are supported and slidably installed in the grooves on both sides of the slide groove 22. During the adjustment of the C-arm 4, the sliding wheels 14 and the supporting bearings 15 are supported and rolled on the side and bottom surfaces of the slide groove 22, respectively, to ensure the stability of the C-arm 4 during the adjustment process.

[0030] like Figure 5As shown, the rotational power assembly 13 includes a motor 16 and a transmission assembly. The rotational power assembly 13 is mounted on a mounting plate 21, which is mounted on a supporting inclined arm 8. A reducer 17 is provided between the motor 16 and the transmission assembly. The transmission assembly includes a drive gear 18 and a transmission gear 19. The drive gear 18 is connected to the output end of the reducer 17, and the transmission gear 19 meshes with the drive gear 18. The synchronous pulley 20 and the transmission gear 19 are coaxially arranged. The shafts of the synchronous pulley 20 and the transmission gear 19 are rotatably mounted on the supporting inclined arm 8, and shaft covers 9 are provided at both ends of the shafts. The motor drives the drive gear 18 to rotate, and the transmission gear 19 rotates accordingly. The synchronous pulley 20 rotates synchronously, thereby driving the synchronous belt 10 to rotate.

[0031] The support slant arm 8 is mounted on the machine body 1 via the cross arm 2. A handle 7 is also provided on one side of the C-shaped arm 4. The operation screen 3 is rotatably mounted on the machine body 1, and the control screen can be operated from any position, making it convenient to use.

[0032] In use, pressing the clockwise or counterclockwise rotation button on the operation screen 3 causes the motor 16 to drive the synchronous pulley 20 to rotate, which in turn drives the synchronous belt 10 to move. Since the two ends of the synchronous belt 10 are fixed to the two ends of the C-arm 4, the C-arm 4 can rotate around its center. The clockwise and counterclockwise buttons on the operation screen 3 control the forward and reverse rotation of the motor 16, corresponding to the clockwise and counterclockwise rotation of the C-arm 4, thereby realizing the electric rotation function of the C-arm. The sliding wheel 14 and the support bearing 15 are supported and slidably installed in the slide groove 22 of the C-arm 4 to ensure that the C-arm 4 remains stable during sliding adjustment, which is convenient for medical staff to operate.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
