Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to an adjustable-angle carbon fiber stent that facilitates intraoperative fluoroscopy. Background Technology
[0002] In orthopedic surgeries, such as fracture reduction and fixation and joint replacement, intraoperative fluoroscopy is a crucial step. Surgeons use fluoroscopic equipment (such as a C-arm machine) to observe in real time the position, shape, reduction, and internal fixation of the patient's leg bones and joints. Accurate and clear images are essential for determining whether the fracture is aligned, whether the internal fixation devices (plates, screws, etc.) are placed correctly, and whether the joint surfaces are smooth. These images directly influence the adjustment of the surgical plan and the final outcome, impacting the patient's postoperative limb function recovery and playing a decisive role in the success of the surgery.
[0003] However, in practical applications, existing equipment suffers from limitations in leg support methods. These methods are simplistic and lack precision, relying heavily on basic mechanical structures or rough manual adjustments. This makes it difficult to accurately achieve specific angle requirements, such as a 90° perpendicular alignment or a 15° inward rotation. Repeated adjustments during surgery are necessary, extending the procedure time. Furthermore, angle deviations can lead to unclear fluoroscopic images, affecting the doctor's diagnosis and operation, thus hindering practical application and operation. Summary of the Invention
[0004] One objective of this invention is to provide an adjustable-angle carbon fiber scaffold that facilitates intraoperative fluoroscopy.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an adjustable angle carbon fiber scaffold that facilitates intraoperative fluoroscopy, comprising a support base and a placement plate: the support base is provided with an adjustment structure inside, and the placement plate is provided with a clamping structure on one side;
[0006] The adjustment structure includes a T-slot, a T-block, a bracket, a connecting shaft, a rotating rod, a gear, a toothed groove, a rotating rod, a worm gear, and a worm. The clamping structure includes a limiting plate, a connecting block, a sliding groove, a slider, a bidirectional screw, a fixing cap, a lever, a clamping plate, a silicone wheel, and a screw block.
[0007] The top of the support base has two T-slots, and the bottom of the placement plate is fixedly connected to two T-blocks. The T-blocks are slidably connected to the inner walls of the corresponding T-slots. The inside of the support base is fixedly connected to two brackets, and a connecting shaft is fixedly connected between the two brackets. A rotating rod is rotatably connected inside the connecting shaft, and a gear is fixedly connected to one end of the rotating rod. The top of the inner wall of the support base has a slot, and the bottom of the placement plate has toothed grooves at equal intervals. The gear passes through the slot and meshes with the toothed grooves.
[0008] Preferably, a worm gear is rotatably connected inside the support base and below the rotating rod, and a worm wheel is fixedly connected to the outer end of the rotating rod away from the gear. The worm wheel meshes with the worm gear, and one end of the worm gear extends to the outer side of the support base and is fixedly connected to a throttle handle.
[0009] Preferably, a limiting plate is fixedly connected to one side of the placement plate, and a sliding groove is provided on the outer side of the limiting plate. Two sliders are slidably connected inside the sliding groove, and a connecting block is fixedly connected between the two sliders. A bidirectional screw is rotatably connected inside the connecting block, and both ends of the bidirectional screw pass through the connecting block. Two levers are rotatably connected to one side of the placement plate and above the bidirectional screw. Two screw blocks are threadedly connected to the outer side of the bidirectional screw, and each screw block is rotatably connected to a corresponding lever.
[0010] Preferably, each lever is rotatably connected to a clamping plate at its top, and two clamping plates are rotatably connected to silicone wheels at equal intervals on their adjacent sides. Silicone strips are fixedly connected at equal intervals to the inner wall of the placement plate, and a silicone pad is fixedly connected to the outer side of the support base on one side of the placement plate.
[0011] Preferably, a scale groove is provided on one side of the support base and below the placement plate, and a pointer is fixedly connected to one side of the placement plate and outside the limiting plate, and the pointer is used in conjunction with the scale groove.
[0012] Preferably, both ends of the bidirectional screw are fixedly connected to blocking blocks, and fixing caps are fixedly connected to the outer side of the bidirectional screw and on both sides of the limiting plate. Anti-slip strips are fixedly connected at equal intervals to the bottom of the support base.
[0013] Preferably, the support base and the placement plate are both made of crystal transparent carbon fiber, and the silicone pad, silicone strip, silicone wheel and anti-slip strip are all made of medical-grade materials.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] (1) This invention allows for precise and flexible angle adjustment through its adjustable structure. By using gears and toothed grooves, combined with a pointer and graduated groove, it can accurately achieve multi-angle adjustments such as 90° or 15° of internal rotation. Whether it is conventional fluoroscopy or special angles such as internal or external rotation, it can be quickly adapted, making intraoperative image acquisition more accurate, helping doctors to clearly observe the structural details of bones, joints, etc., shortening the diagnostic and judgment time, and improving surgical efficiency. The support base and placement plate made of crystal carbon fiber material provide unobstructed fluoroscopy and clear imaging, avoiding image blurring caused by material interference, reducing repeated fluoroscopy operations, reducing the risk of radiation exposure for patients, and allowing the surgical team to obtain effective image information more efficiently.
[0016] (2) This invention uses a bidirectional screw, lever, and clamping plate in a clamping structure to stably fix the foot. The medical-grade silicone material, such as silicone wheels and silicone strips, is soft and non-slip, which can firmly fix the leg and avoid skin damage and patient discomfort caused by clamping during the operation. The stable position of the leg during the operation can prevent fluoroscopic image misalignment and surgical operation deviation caused by movement, ensuring the quality of the operation and reducing the surgical risk. The reliable structural design, with the sliding cooperation of the T-slot and T-block, makes it difficult for the placement plate to shift or shake when adjusting the angle. The limiting plate, sliding groove and other components in the clamping structure ensure smooth and stable clamping action. Long-term use is not prone to loosening or jamming, improving the overall durability and stability of the stent and adapting to the complex scenarios of frequent operation during the operation and use by different patients.
[0017] (3) This invention, through structural adjustment, only requires rotating the handle, and the clamping operation is completed by rotating the fixed cap to drive the bidirectional screw. Medical staff can quickly learn and operate it without complicated learning costs. The status of the stent can be quickly adjusted during the operation to cooperate with the surgical procedure. The clear scale groove and pointer scale display allow the surgical team members to reach a consensus on the leg angle, which is convenient for communication and cooperation. For example, in orthopedic surgery, the surgeon and the imaging technician can accurately coordinate according to the scale, improve the efficiency of team collaboration, and reduce operational errors caused by communication errors. The crystal transparent carbon fiber material not only meets the requirements of fluoroscopy, but also has high strength and relatively light weight, which not only ensures the support of the stent, but also facilitates the handling and adjustment of the position during the operation, reducing the operating burden of medical staff. The medical silicone parts (silicone pads, silicone strips, etc.) meet medical safety standards, have no adverse reactions when in contact with the human body, reduce the risk of infection and allergies during the operation, improve the patient's experience during the operation, and make the hospital more compliant and safe in the use of consumables.

[0033] A worm gear 13 is rotatably connected inside the support base 1 and below the rotating rod 11. A worm wheel 12 is fixedly connected to the outer side of the rotating rod 11 and away from the gear 9. The worm wheel 12 meshes with the worm gear 13. One end of the worm gear 13 extends to the outer side of the support base 1 and is fixedly connected to a throttle 14.
[0034] A limiting plate 20 is fixedly connected to one side of the placement plate 3. A sliding groove 22 is provided on the outer side of the limiting plate 20. Two sliders 23 are slidably connected inside the sliding groove 22. A connecting block 21 is fixedly connected between the two sliders 23. A bidirectional screw 24 is rotatably connected inside the connecting block 21. Both ends of the bidirectional screw 24 pass through the connecting block 21. Two levers 19 are rotatably connected to one side of the placement plate 3 and above the bidirectional screw 24.

[0035] The top of each lever 19 is rotatably connected to a clamping plate 28. The two clamping plates 28 are rotatably connected to silicone wheels 29 at equal intervals on their adjacent sides.

[0039] Working principle:
[0040] In use, turning the handle 14 rotates the worm gear 13. Because the worm wheel 12 meshes with the worm gear 13, the worm wheel 12 drives the rotating rod 11 to rotate synchronously. The gear 9 on the rotating rod 11 rotates accordingly, meshing with the bottom toothed groove 10 of the placement plate 3. The placement plate 3 slides along the top T-groove 2 of the support base 1 via the bottom T-block 4, achieving angle adjustment. The pointer 16, in conjunction with the scale groove 15, precisely displays the adjusted angle, meeting the intraoperative fluoroscopic angle requirements such as 90° perpendicular to the ground or 15° inward rotation. The bracket 7 and connecting shaft 8 provide support for the rotation of the rotating rod 11, ensuring stability during the adjustment process.
[0041] Rotating the fixing cap 25 drives the bidirectional screw 24. Screw blocks 26 are threadedly connected to the bidirectional screw 24 and rotatably connected to the lever 19. The top of the lever 19 is connected to the clamping plate 28. When the bidirectional screw 24 rotates, the two screw blocks 26 move in opposite directions along the screw, causing the lever 19 to swing, making the clamping plate 28 move closer or further away, thus completing the foot clamping or releasing. The silicone wheel 29 of the clamping plate 28 and the silicone strip 5 on the inner wall of the placement plate 3 increase friction and protect the skin. The limiting plate 20, sliding groove 22, slider 23, and connecting block 21 ensure the stability of the screw rotation and lever swing. The fixing cap 25 and blocking block 27 prevent the screw blocks from detaching.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
