Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical imaging equipment technology, and in particular to a C-arm support device with a rotatable angle. Background Technology
[0002] C-arm X-ray machines are indispensable imaging equipment in modern medical surgery. Named for their resemblance to the letter "C," they are primarily used for real-time dynamic imaging in orthopedic, surgical, and interventional procedures, providing surgeons with precise lesion localization and surgical navigation. One end of the C-arm houses the X-ray tube, while the other end contains an image intensifier or flat-panel detector. Its core structure typically consists of a C-shaped arm and a support device for supporting and moving the arm. Currently, the most common C-arm support devices in clinical practice are floor-standing and suspended types. Floor-standing support devices are the most widely used due to their flexibility and lower space requirements in the operating room.
[0003] When using existing C-arm support devices, their rotational movement is mostly strictly limited to preset horizontal and vertical axes. When encountering complex surgical positions or when a specific tilt angle is required for projection, the existing rotation method is difficult to quickly and accurately adjust the C-arm to the ideal angle. Doctors often need to repeatedly try to move the entire device or adjust the patient's position, which is cumbersome and does not facilitate improving the ease of adjustment. Utility Model Content

The connecting piece is connected to the slide rail seat.
[0009] The multi-angle rotating assembly includes an assembly frame, in which a mounting rod is rotatably connected. A connecting fastener is fixedly connected to the surface of the mounting rod, and the connecting fastener is connected to the track support of the C-arm body.

[0016] (III) Beneficial Effects
[0017] This utility model provides a C-arm support device with a rotatable angle, which has the following beneficial effects:
[0018] 1. This rotatable C-arm support device, through the setting of horizontal rotation components and multi-angle rotation components, allows the C-arm body to rotate in the horizontal plane and adjust the tilt angle, increasing the freedom of angle adjustment. This allows doctors to easily and quickly adjust the C-arm to the optimal projection angle required for any complex surgical position, avoiding the cumbersome process of doctors having to repeatedly try to move the entire device or adjust the patient's position when encountering complex surgical positions or requiring a specific tilt angle for projection. This helps to improve the convenience of the device.
[0019] 2. This rotatable C-arm support device, through the setting of worm gear and worm wheel, has a natural reverse self-locking function due to the smooth transmission and low noise characteristics of the worm gear mechanism. This means that when the horizontal rotation is adjusted to the correct position, the C-arm can be reliably locked in the horizontal direction without the need for additional brakes or locking devices. This effectively prevents accidental displacement or "drift" caused by external forces or the weight of the equipment itself during surgery, greatly improving the stability and safety of the equipment when it is in static operation, and ensuring image quality and surgical safety.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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 scope of protection of the present utility model.
[0026] Please see Figures 1 to 4 This utility model provides a technical solution: a C-arm support device with rotatable angle, including a base 1 and a C-arm body 2. A lifting mechanism is provided inside the base 1, and a horizontal rotating component 3 is fixedly connected to the top of the lifting mechanism. A slide rail seat 4 is fixedly connected to the top of the horizontal rotating component 3. A rotating box 5 is provided on the slide rail seat 4, and a multi-angle rotating component 7 is connected inside the rotating box 5 through a rotating mechanism 6.
[0027] The horizontal rotation assembly 3 includes a mounting plate 301 fixedly connected to the top of the lifting mechanism. Two bearing seats are fixedly mounted on the surface of the mounting plate 301, and a worm gear 302 is connected inside each bearing seat. A worm wheel 303 meshes with the upper part of the worm gear 302, and a connecting piece 304 is provided at the upper end of the worm wheel 303, connecting the connecting piece 304 to the slide rail seat 4. Through the arrangement of the worm gear 302 and worm wheel 303, the mechanism formed by the worm gear 303 and worm gear 302 has the characteristics of smooth transmission and low noise. It naturally possesses a reverse self-locking function, which means that when the horizontal rotation is adjusted to the correct position, the C-arm can be reliably locked in the horizontal direction without the need for additional brakes or locking devices. This effectively prevents accidental deviation or "drift" caused by external forces or the weight of the equipment itself during surgery, greatly improving the stability and safety of the equipment during static operation, ensuring image quality and surgical safety.
[0028] The multi-angle rotating component 7 includes an assembly frame 701, with a mounting rod 702 rotatably connected inside the assembly frame 701. A connecting fastener 703 is fixedly connected to the surface of the mounting rod 702. The connecting fastener 703 is connected to the track support 11 of the C-arm body 2. Through the setting of the horizontal rotating component 3 and the multi-angle rotating component 7, the C-arm body 2 can rotate and adjust its tilt angle in the horizontal plane, increasing the freedom of angle adjustment. This allows doctors to easily and quickly adjust the C-arm to the optimal projection angle required for any complex surgical position, avoiding the cumbersome process of doctors having to repeatedly try to move the entire device or adjust the patient's position when encountering complex surgical positions or requiring a specific tilt angle for projection. This helps to improve the convenience of the device.
[0029] The lifting mechanism consists of a hydraulic lifting cylinder and a hydraulic system. The inner rod of the hydraulic lifting cylinder has a scale on the outside. The lifting mechanism allows the operator to accurately observe and control the vertical height of the C-arm body 2, which facilitates the rapid positioning of the initial reference height under different surgical needs. It also works in conjunction with the rotation angle to achieve precise positioning in three-dimensional space, thereby improving the standardization and repeatability of the surgical procedure.
[0030] The lower part of the rotating housing 5 slides inside the slide rail seat 4, and a locking device is provided on the outer side of the slide rail seat 4. The outer side of the rotating housing 5 is provided with a scale. Through the setting of the slide rail and the locking device, the axial extension and retraction of the C-arm relative to the support column is realized. It is also used in conjunction with the multi-angle rotating component 7.
[0031] The rotating mechanism 6 includes a drive motor 601 fixedly installed inside the rotating housing 5. One end of the drive motor 601 is connected to a rotating mounting part 602, which is fixedly connected to the assembly frame 701. The drive motor 601 provides a strong and controllable power source for the multi-angle rotating assembly 7, realizing the electric adjustment of the C-arm tilt angle.
[0032] A folding handle 8 is fixedly installed at one end of the worm gear 302. The folding handle 8 is used to rotate the worm gear 302. By setting the folding handle 8, the worm gear 302 can be rotated when rotating horizontally, so that it drives the worm wheel 303 to rotate. After use, the handle can be folded up to avoid collision interference to personnel or the environment during equipment movement or operation, thus taking into account both operational flexibility and safety.
[0033] A mounting bracket 9 is connected to the bottom of the worm gear 303. The mounting bracket 9 is fixedly installed on the mounting plate 301. The mounting bracket 9 provides a stable and reliable bottom support for the worm gear 303, ensuring the accuracy and stability of the meshing transmission.
[0034] One end of the mounting rod 702 is connected to a servo motor 10, which is fixedly mounted on the assembly frame 701. Through the setting of the servo motor 10, the rotation of the mounting rod 702, i.e. the tilt angle of the C-arm body 2, can be precisely controlled in a closed loop.
[0035] In this invention, the working steps of the device are as follows:
[0036] First step: Move the device to the vicinity of the surgical area via the base 1. According to the surgical needs, adjust the initial height of the C-arm body 2 via the lifting mechanism at the bottom. The operator can observe the scale on the rod inside the hydraulic cylinder for precise setting. Then, the folding handle 8 can be manually unfolded and rotated. The worm gear 302 drives the worm wheel 303, which in turn drives the slide rail seat 4 and the rotating box 5 above to rotate as a whole in the horizontal plane, so that the C-arm is roughly aligned with the surgical target area.
[0037] The second step: If it is necessary to avoid obstacles or fine-tune the center of the C-arm, the locking piece on the outside of the slide rail seat 4 can be loosened, and the rotating box 5 can be manually pushed to slide back and forth along the slide rail. After determining the position, it can be re-locked. Then, the servo motor 10 on the multi-angle rotation component 7 is started to drive the mounting rod 702 to rotate, and then the C-arm body 2 is tilted and adjusted through the connecting fixing piece 703 to adjust the C-arm to the optimal projection angle required for surgery. It should be noted that the device structure and drawings of this utility model mainly describe the principle of this utility model. In terms of the technical aspects of this design principle, the setting of the power mechanism, power supply system and control system of the device is not fully described. However, under the premise that those skilled in the art understand the principle of the above utility model, the specific details of its power mechanism, power supply system and control system can be clearly understood. The control method in the application document is automatic control through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming.
