Description

Technical Field

[0001] This invention relates to the field of scoliosis correction and comparison technology, specifically a foldable, sterilized, and fluoroscopic comparison device for scoliosis correction. Background Technology

[0002] In scoliosis correction surgery, real-time assessment of the coronal plane balance of the spine and the correction effect is a core aspect of ensuring surgical quality. It is necessary to use other reference objects as auxiliary tools in conjunction with X-ray fluoroscopy to complete the image comparison before and after correction in order to accurately determine the degree of scoliosis correction.

[0003] Currently, there is no standard intraoperative correction and comparison device for scoliosis. In routine surgeries, non-dedicated devices that can be visualized (such as straight titanium rods) are used for reference and comparison. These devices can only assess the correction in the coronal plane and cannot simultaneously assess the balance of the shoulders and pelvis. Furthermore, the coverage area cannot be adjusted according to the patient's actual situation, making it difficult for the tool to accurately correspond to the target spinal region. Correction and comparison under X-ray fluoroscopy lack effective reference and cannot accurately assess the correction effect. In addition, the fixed size makes it inconvenient to carry. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a foldable, sterile, and fluoroscopic comparison device for scoliosis correction. This device solves the problem that traditional scoliosis surgery cannot simultaneously assess the balance of both shoulders and pelvis, as well as the coronal plane correction assessment of the spine. Furthermore, the device features a telescopic design that can be adjusted according to the length of the patient's torso, achieving comprehensive coverage of the spinal region for patients of different heights. The metal material allows for effective reference and accurate assessment of the correction effect under X-ray fluoroscopy. The telescopic design also solves the problems of portability and sterilization.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a foldable, disinfected, and fluoroscopic contrast device for scoliosis correction, comprising a first support plate, a cylinder 1 fixedly connected to the top of the first support plate, a cylinder 2 slidably connected to the inner wall of the cylinder 1, a telescopic rod slidably connected to the inner wall of the cylinder 2, a first limiting ring fixedly connected to the top of the cylinder 1, a first locking screw threadedly connected to the inner thread of the first limiting ring, one end of the first locking screw abutting against the outer wall of the cylinder 2, a second limiting ring fixedly connected to the top of the cylinder 2, a second locking screw threadedly connected to the inner thread of the second limiting ring, one end of the second locking screw abutting against the outer wall of the telescopic rod, a second support plate fixedly connected to the top of the telescopic rod, and a folding assembly installed on one side of the first support plate.

[0006] By adopting the above technical solution, the balance scale is telescopic by sliding the second cylinder inside the first cylinder and the telescopic rod inside the second cylinder. When performing scoliosis comparison work, it can be extended to make more accurate and effective comparisons, thereby accurately assessing the corrective effect. After use, it can be shortened, which greatly facilitates carrying. This allows the device to flexibly adapt to different usage scenarios and improves the ease of use.

[0007] Preferably, the folding assembly includes a rotating shaft, and the rotating shaft is rotatably connected inside both the first support plate and the second support plate. Both ends of the rotating shaft are fixedly connected to a connecting plate, and one end of the connecting plate is rotatably connected to a connecting shaft on opposite sides. The outer walls of the two connecting shafts are respectively fixedly connected to a second folding plate and a first folding plate.

[0008] Preferably, a fixing plate is fixedly connected to the outer wall of the cylinder, a fastening screw is threadedly connected to the inside of the fixing plate, the outer wall of the fastening screw is threadedly connected to the inside of the first folding plate, and a nut is threadedly connected to the bottom of the fastening screw.

[0009] Preferably, a fixing plate two is fixedly connected to the outer wall of the telescopic rod, a fastening screw two is threadedly connected to the inner wall of the fixing plate two, the outer wall of the fastening screw two is threadedly connected to the inner wall of the second folding plate, and a nut two is threadedly connected to the top of the fastening screw two.

[0010] Preferably, a first rubber belt is fixedly connected to one end of the outer wall of the second support plate, and a second rubber belt is fixedly connected to one end of the outer wall of the first support plate.

[0011] Preferably, the top of the first support plate is symmetrically fixedly connected to a connecting plate, the top of the connecting plate is fixedly connected to a mounting frame, and the top of the mounting frame is provided with an output port.

[0012] Preferably, a support column is fixedly connected inside the mounting frame, a drum is rotatably connected to the outer wall of the support column, a leather spring is fixedly connected to the outer wall of the support column, and one end of the leather spring is fixedly connected inside the drum.

[0013] Preferably, a metal roll is installed on the outer wall of the drum, one end of the metal roll is fixedly connected to one side of the leather spring, the other end of the metal roll is located in the output port, the other end of the metal roll is fixedly connected to the bottom of the second support plate, and scale lines are evenly arranged on one side of the metal roll.

[0014] Preferably, the first cylinder, the second cylinder, and the telescopic rod are of the same length, and the first support plate, the second support plate, the first folding plate, and the second folding plate are all of the same size.

[0015] Preferably, the inner diameter of the first cylinder is greater than or equal to the outer diameter of the second cylinder, and the inner diameter of the second cylinder is greater than or equal to the outer diameter of the telescopic rod.

[0016] Working principle: During scoliosis correction, the device is removed and placed on the corresponding area of ​​the patient's body. X-ray fluoroscopy is performed before and after correction for comparison. For extension / retraction adjustment, loosen the first locking screw to allow cylinder two to slide into cylinder one to the appropriate position, or loosen the second locking screw to pull the telescopic rod out of cylinder two to the required length. Finally, tighten both locking screws to abut against the outer walls of cylinder two and the telescopic rod, respectively. For folding after use, unscrew nuts one and two, loosen fastening screws one and two, first align the first and second folding plates perpendicular to the first and second support plates respectively around the rotation axis, then rotate the first and second folding plates around the connecting axis until they are perpendicular to the first and second support plates respectively. The support plates are parallel. The first folding plate is fitted into the second rubber belt, and the second folding plate is fitted into the first rubber belt and fixed. When used again, the first and second folding plates are detached from the second and first rubber belts respectively. They are rotated under the cooperation of the rotating shaft and the connecting shaft until the first folding plate contacts the bottom of the first fixed plate and the second folding plate contacts the top of the second fixed plate. The first and second fastening screws and the first and second nuts are tightened. At the same time, when the telescopic rod extends, the second support plate moves up and drives the metal roll to be released from the drum. The rotation of the drum causes the leather spring to deform and store energy. When the telescopic rod shortens, the leather spring releases energy and drives the drum to rotate in the opposite direction, realizing the automatic winding of the metal roll. The entire device is made of metal.

[0017] This invention provides a foldable, sterile, and fluoroscopic contrast device for scoliosis correction. It has the following beneficial effects: 1. This invention achieves the telescopic function of the balance scale by sliding the second cylinder inside the first cylinder and the telescopic rod inside the second cylinder. When performing scoliosis comparison work, it can be extended to make more accurate and effective comparisons and match patients of different heights, so as to accurately assess the corrective effect. After use, it can be shortened, which greatly facilitates carrying and makes the device flexible to adapt to different usage scenarios, thus improving the convenience of use.

[0018] 2. By unscrewing nuts one and two and loosening fastening screws one and two, the first folding plate and the second folding plate are first made perpendicular to the first support plate and the second support plate around the rotation axis, respectively. Then, the first folding plate and the second folding plate are rotated around the connecting axis until they are parallel to the first support plate and the second support plate, respectively. The first folding plate is then fitted into the second rubber belt and the second folding plate is fitted into the first rubber belt for fixation. This further reduces the overall size of the device and makes it easier to carry.

[0019] 3. In this invention, as the telescopic rod extends, the second support plate moves upward, causing the metal roll to be released from the drum. The drum then rotates, and the leather spring deforms due to the rotation of the drum, storing energy. When the telescopic rod shortens, the leather spring releases the stored energy, generating a force to restore its original shape, causing the drum to rotate in the opposite direction. This achieves automatic winding of the metal roll. The scale lines on the metal roll provide a clear reference for scoliosis correction, helping to improve the accuracy and effectiveness of the correction. Attached Figure Description

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 -Appendix Figure 5This invention provides a foldable, disinfected, and fluoroscopic comparison device for scoliosis correction, comprising a first support plate 1, a cylinder 2 fixedly connected to the top of the first support plate 1, a cylinder 201 slidably connected to the inner wall of the cylinder 2, a telescopic rod 202 slidably connected to the inner wall of the cylinder 201, a first limiting ring 203 fixedly connected to the top of the cylinder 2, a first locking screw 204 threadedly connected to the inner thread of the first limiting ring 203, one end of the first locking screw 204 abutting against the outer wall of the cylinder 201, a second limiting ring 205 fixedly connected to the top of the cylinder 201, a second locking screw 206 threadedly connected to the inner thread of the second limiting ring 205, one end of the second locking screw 206 abutting against the outer wall of the telescopic rod 202, a second support plate 207 fixedly connected to the top of the telescopic rod 202, and a folding assembly installed on one side of the first support plate 1.

[0024] Specifically, during the scoliosis correction process, the device can be removed and placed on the patient's body for X-ray fluoroscopy to compare the correction effect. An X-ray is taken before correction and again after correction, and the two results are compared. When performing scoliosis comparison, the device needs to be adjusted according to the patient's height. The operator can first loosen the first locking screw 204 so that it is no longer tightly pressed against the outer wall of the second cylinder 201, allowing the second cylinder 201 to slide freely inside the first cylinder 2. The second cylinder 201 is then pulled upwards to the appropriate position. Next, the second locking screw 206 is loosened to release the fixation on the telescopic rod 202, and the telescopic rod 202 is pulled upwards from the second cylinder 201 to the required length. Finally, the first locking screw 204 and the second locking screw 206 are tightened respectively, so that they are tightly pressed against the outer walls of the second cylinder 201 and the telescopic rod 202, completing the device extension operation. This allows for more precise and effective comparison, matching patients of different heights, and thus accurately assessing the correction effect. After use, follow the reverse order: first loosen the locking screw, then retract the telescopic rod 202 into the second cylinder 201, then retract the second cylinder 201 into the first cylinder 2, and finally tighten the locking screw to fix it. This allows the device to flexibly adapt to different usage scenarios and improves the ease of use. The overall size of the device is further reduced by the folding components. The lengths of the first cylinder 2, the second cylinder 201, and the telescopic rod 202 are all 30 centimeters.

[0025] Please see the appendix Figure 1 -Appendix Figure 6 The folding assembly includes a rotating shaft 3. The rotating shaft 3 is rotatably connected inside the first support plate 1 and the second support plate 207. The two ends of the rotating shaft 3 are fixedly connected to the connecting plate 301. The connecting plate 301 is rotatably connected to the connecting shaft 302 on one side opposite to the other. The outer walls of the two connecting shafts 302 are respectively fixedly connected to the second folding plate 303 and the first folding plate 304. A fixing plate 4 is fixedly connected to the outer wall of the cylinder 2. A fastening screw 401 is threadedly connected to the inside of the fixing plate 4. The outer wall of the fastening screw 401 is threadedly connected to the inside of the first folding plate 304. A nut 402 is threadedly connected to the bottom of the fastening screw 401. The outer wall of the telescopic rod 202 is fixedly connected to a fixing plate 403. The inner thread of the fixing plate 403 is connected to a fastening screw 404. The outer wall of the fastening screw 404 is threadedly connected to the second folding plate 303. The top of the fastening screw 404 is threadedly connected to a nut 405. A first rubber belt 5 is fixedly connected to one end of the outer wall of the second support plate 207, and a second rubber belt 501 is fixedly connected to one end of the outer wall of the first support plate 1.

[0026] Specifically, when performing the folding operation after use, the operator first unscrews nuts 402 and 405, then loosens fastening screws 401 and 404 to release the fixation of the first folding plate 304 and the second folding plate 303. Then, the first folding plate 304 and the second folding plate 303 are rotated around the rotating shaft 3 and the connecting shaft 302, respectively. When rotating around the rotating shaft 3, the first folding plate 304 is perpendicular to the first support plate 1, and the second folding plate 303 is perpendicular to the second support plate 207. Next, the first folding plate 304 and the second folding plate 303 are rotated around the connecting shaft 302, making them parallel to the first support plate 1 and the second support plate 207, respectively. Finally, the first folding plate 304 is fitted into the second rubber belt 501, and the second folding plate 303 is fitted into the first rubber belt 5, achieving the folding and fixing operation, further reducing the overall size of the device and making it easier to carry. When needed, the operator unfolds the balance scale, first detaches the first folding plate 304 and the second folding plate 303 from the second rubber belt 501 and the first rubber belt 5 respectively, and rotates the folding plates with the cooperation of the rotating shaft 3 and the connecting shaft 302 until the first folding plate 304 contacts the bottom of the fixed plate 4 and the second folding plate 303 contacts the top of the fixed plate 403. At this time, tighten the fastening screws 401 and 404 respectively, and finally fix the unfolded balance scale with nuts 402 and 405, so that it can be placed on the patient for comparison. The lengths of the first support plate 1 and the second support plate 207, as well as the first folding plate 304 and the second folding plate 303, are all 15 cm.

[0027] Please see the appendix Figure 1 Appendix Figure 7 A connecting plate 6 is symmetrically fixedly connected to the top of the first support plate 1, and a mounting frame 601 is fixedly connected to the top of the connecting plate 6. An output port 602 is opened on the top of the mounting frame 601. A support column 7 is fixedly connected inside the mounting frame 601. A drum 701 is rotatably connected to the outer wall of the support column 7. A leather spring 702 is fixedly connected to the outer wall of the support column 7. One end of the leather spring 702 is fixedly connected inside the drum 701. A metal roll 703 is installed on the outer wall of the drum 701. One end of the metal roll 703 is fixedly connected to one side of the leather spring 702, and the other end of the metal roll 703 is located inside the output port 602. The other end of the metal roll 703 is fixedly connected to the bottom of the second support plate 207. Scale lines 704 are evenly arranged on one side of the metal roll 703.

[0028] Specifically, when the telescopic rod 202 extends, the second support plate 207 moves upward, causing the metal roll 703 to be released from the drum 701. The drum 701 then rotates, and the leather spring 702 deforms due to the rotation of the drum 701, storing energy. When the telescopic rod 202 shortens, the leather spring 702 releases the stored energy, generating a force to restore its original shape, causing the drum 701 to rotate in the opposite direction, thereby realizing the automatic winding of the metal roll 703. The scale lines 704 on the metal roll 703 provide a clear reference for scoliosis correction, which helps to improve the accuracy and effectiveness of the correction.

[0029] Please see the appendix Figure 1 -Appendix Figure 6 The lengths of cylinder 1 2, cylinder 2 201 and telescopic rod 202 are the same, and the dimensions of the first support plate 1 and the second support plate 207, as well as the first folding plate 304 and the second folding plate 303 are all the same. The inner diameter of cylinder 1 2 is greater than or equal to the outer diameter of cylinder 2 201, and the inner diameter of cylinder 2 201 is greater than or equal to the outer diameter of telescopic rod 202.

[0030] Specifically, the proper matching of the inner diameter of cylinder 1 2 with the outer diameter of cylinder 2 201, and the inner diameter of cylinder 2 201 with the outer diameter of telescopic rod 202, allows cylinder 2 201 to slide smoothly within cylinder 1 2 and telescopic rod 202 to move smoothly within cylinder 2 201. This avoids jamming or shaking caused by size mismatch, thus ensuring the accuracy of scoliosis comparison work. The same size of the support plates facilitates folding operations, and the entire device is made of metal, allowing for thorough sterilization before use in surgery.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
