Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a coccyx repositioning device. Background Technology

[0002] The coccyx, located at the very end of the spine, is an evolutionarily degenerated structure. Treatment for coccyx misalignment includes using nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve pain, along with heat therapy or ultrasound treatment. In cases of significant coccyx abnormality, a small injection of steroids can be administered to the affected area to reduce inflammation. Symptoms usually improve significantly within a week of the injection, and a second injection may be given a month later if necessary. Additionally, placing a donut-shaped cushion on your seat can reduce pressure on the coccyx when sitting.

[0003] If the above treatments are ineffective and the coccyx cannot be repositioned, intra-anal manipulation can be used. This effectively relieves spasms and pain in the muscles around the coccyx and is an effective treatment for coccyx dislocation. In clinical practice, intra-anal manipulation involves the doctor inserting their fingers directly into the patient's anus to push the fractured coccyx upwards, while simultaneously applying downward pressure to the coccyx externally to achieve repositioning.

[0004] However, in actual clinical practice, there are many problems: it is difficult for doctors to apply force with their fingers inside the patient's anus, making the procedure difficult and resulting in poor efficacy. Furthermore, patient privacy is not protected, leading to a poor treatment experience.

[0005] To address this issue, the existing patent "201911398891.X" entitled "A Coccyx Repositioning Device" utilizes a C-shaped fixing sleeve. An inner push rod slides within one end of the sleeve, while an outer pressure rod slides within the other end. Both the inner and outer pressure rods are fitted with springs. A hollow handle connects to the fixing sleeve, and a push rod for actuating the inner and outer pressure rods is movably mounted within the handle. The doctor can directly operate the push rods externally, which allows for better force application, improved efficacy, and easier operation and force control compared to inserting fingers into the body. The C-shaped fixing sleeve guides the inner and outer pressure rods, positioning them precisely against the patient's coccyx. The doctor only needs to rotate the push rod to move the inner and outer pressure rods individually, requiring minimal adjustment, making operation convenient. Furthermore, the C-shaped fixing sleeve provides good stability directly against the patient's coccyx, making it easy for the doctor to grip and operate.

[0006] While the device can solve the issues of force application and privacy, the following problems still exist: 1. While existing technology can use devices to simulate a surgeon's fingers for repositioning, both the inner push rod and the outer pressure rod of this device are C-shaped structures, and are part of a standard truncated circular structure. This means that after the inner push rod is fully extended, it can close into a circle. However, in reality, when a surgeon repositions a patient's coccyx, the technique is actually similar to using "pliers" to ensure a larger contact area between the fingers and the coccyx. Crucially, this allows the fingers to be inserted into the patient's anus for repositioning. The existing C-shaped structure can only be inserted into the anus, unable to reach the coccyx, and cannot extend the inner push rod. Furthermore, because the inner push rod and outer pressure rod are two pointed structures, the contact area with the coccyx is very small, making it impossible to achieve contact and clamping of the dislocated coccyx surface for repositioning.

[0007] 2. The depth of the coccyx inside the anus varies from person to person, and the degree of misalignment also varies. The existing device is a calibration structure and cannot achieve structural adjustment, thus failing to meet the targeted treatment needs of different patients with different degrees of misalignment. Summary of the Invention

[0008] The purpose of this invention is to provide a coccyx reduction device. Its simulated finger plate structure is highly similar to the structure used by medical personnel's fingers, effectively mimicking the structure of a real finger. The device uses a drive component to move the simulated finger plate, allowing it to be fully inserted into the patient's anus. The reduction technique closely resembles that of a real doctor, thus achieving coccyx reduction. Compared to existing doctor's finger manipulation techniques, this device is more time-saving and labor-saving, and can better control the reduction force. The inclusion of an air cushion improves comfort and increases the contact area, enhancing the accuracy and speed of reduction. The rocker arm and gear set reduce torque while increasing transmission speed, resulting in less effort, improved efficiency, reduced physical exertion for medical personnel, time savings, and less patient pain. The rotating rod assembly, compared to conventional surgical forceps, has a smaller handle size and better control over the operating force. The end of the rotating rod assembly is a curved arc similar to a finger, and a silicone layer is bonded to the surface, allowing for better skin contact and reducing patient discomfort. It is equipped with a Z-shaped rod with different torques and adjustable force, which also adjusts the position and distance of the simulated finger plate. This allows for better suitability for coccyx repositioning and avoids the situation where the simulated finger plate cannot be properly positioned due to improper size, thus preventing accurate coccyx repositioning.

[0009] To achieve the above-mentioned technical effects, the technical solution adopted by the present invention is as follows: A coccyx repositioning device includes a mounting column and a mounting cylinder. The mounting cylinder has a cavity, and a drive assembly is disposed inside the cavity. The end of the drive assembly slides through the mounting column and is connected to a rotating rod assembly via a spring. The end of the rotating rod assembly is provided with an arc-shaped simulated finger plate.

[0010] Preferably, the drive assembly includes a rocker arm, a gear set, and a rack plate. Two rack plates are slidably disposed in the mounting column. The ends of the two rack plates located inside the mounting cylinder are provided with racks. The racks mesh with the gear set. One of the gears in the gear set is fixedly connected to the rocker arm. The rocker arm is rotatably disposed by passing through the outer wall of the mounting cylinder.

[0011] Preferably, the gear set includes a drive gear, which is fixedly connected to the rocker arm. The drive gear meshes with a secondary gear, and the secondary gear and the large gear rotate coaxially. The large gear meshes with a rack plate, and at the same time, the large gear meshes with a small gear. The small gear is bonded to another rack plate, thereby realizing the transmission of the gear set by the rocker arm.

[0012] Preferably, the rotating rod assembly includes a first Z-shaped rod and a second Z-shaped rod. The ends of the first Z-shaped rod and the second Z-shaped rod are connected to the ends of the rack plate by springs. A support rod is fixedly provided at the outer end of the mounting column. A vertical plate is vertically provided at the end of the support rod. The first Z-shaped rod and the second Z-shaped rod are rotatably provided at the ends of the vertical plate and are located on both sides respectively.

[0013] Preferably, the first Z-shaped rod has several through holes, and the corresponding end of the vertical plate has a through hole of the same diameter. Bolts are installed in the through holes to enable the rotation of the first Z-shaped rod.

[0014] Preferably, both the first Z-shaped rod and the second Z-shaped rod are connected to an arc-shaped simulated finger plate at their ends. The simulated finger plate of the second Z-shaped rod is larger than the simulated finger plate connected to the first Z-shaped rod, and a C-shaped air cushion is wrapped around the outer surface of the simulated finger plate of the second Z-shaped rod.

[0015] Preferably, the end of the mounting column is further provided with a piston cylinder, and an L-shaped piston rod is provided inside the piston cylinder. The end of the piston rod is fixedly provided on the side wall of the rack plate, and the piston cylinder and the C-shaped air cushion are connected by an air pipe.

[0016] A method for using a coccyx reduction device: First, insert a C-shaped air cushion into the patient's anus, making it contact the misaligned coccyx. Then, manually crank the lever, which drives the active gear to rotate. The active gear drives the intermediate gear to rotate, which coaxially drives the large gear to rotate. The large gear drives the small gear to rotate. The large and small gears simultaneously move two rack plates into the inner cavity, tightening the spring. This further moves the ends of the first and second Z-shaped rods closer together and towards the mounting column. The first and second Z-shaped rods rotate around corresponding fulcrums on the vertical plate, bringing them closer together. The second Z-shaped rod pushes the fractured coccyx upwards, while the first Z-shaped rod presses downwards at the external coccyx, achieving coccyx reduction. During this process, as the rack plates move inwards, they drive the piston rod into the piston cylinder, inflating the C-shaped air cushion and increasing its pushing force, which is beneficial for the reduction of the misaligned coccyx.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The simulated finger plate structure of this invention has a very high similarity to the structure of a medical professional's finger operation, and can well simulate the structure of a real finger. The device of this invention drives the simulated finger plate to move through a driving component, and can be fully inserted into the patient's anus. The repositioning movement technique is close to that of a real doctor, thereby realizing the repositioning of the patient's coccyx. Compared with existing doctor finger operations, the device of this invention is more time-saving and labor-saving, and can better control the repositioning force. It is equipped with an air cushion, which improves comfort and increases the contact area, thereby improving the accuracy and speed of repositioning. 2. This invention is equipped with a rocker arm and a gear set. The rocker arm makes operation easier for medical staff. The gear set has different diameters for each gear. The small gear drives the large gear to rotate, and the large gear drives the small gear to mesh, further meshing with the rack plate. This reduces torque and increases transmission speed. This design is more labor-saving, improves work efficiency, reduces the physical exertion of medical staff, saves time, and reduces the pain and suffering of patients. 3. This invention is equipped with a rotating rod assembly, and a simulated finger plate is provided on the rotating rod assembly. The rotating rod assembly is similar to a lever. Through linkage operation with the drive assembly, the size of the forceps handle is reduced compared with the general surgical forceps structure, and the operating force can be better controlled. In addition, the end of the rotating rod assembly structure is a curved arc shape like a finger, and a silicone layer is bonded to the surface, which can better fit the patient's skin and reduce the discomfort caused to the patient. 4. The present invention is equipped with a cylinder and an air cushion. While the rack plate of the drive component slides, it can drive the piston rod of the cylinder to move, thereby filling the air cushion. The greater the lifting force of the reset device, the more fully the air cushion is inflated, avoiding discomfort caused by hard contact between the simulated finger plate and the patient's body, and greatly improving the patient's comfort. 5. The first Z-shaped rod of the present invention has several through holes. In use, the different through holes of the first Z-shaped rod are connected to the vertical plate, so that the two Z-shaped rods have different torques and the adjustment force is also different. At the same time, the position distance of the simulated finger plate is adjusted, which can be better suited for the patient's coccyx repositioning and avoid the situation where the size is not suitable, which would cause the simulated finger plate to not enter the appropriate position and thus fail to accurately achieve the repositioning of the patient's coccyx.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example

[0022] See attached document Figures 1-8 A coccyx repositioning device includes an integrally formed mounting post 1 and mounting cylinder 2. Both the mounting post 1 and the mounting cylinder 2 are cylindrical structures and are made of medical-grade stainless steel. The cylindrical structure of the mounting cylinder 2 makes it easy for doctors to hold with one hand, thus improving its usability.

[0023] The mounting cylinder 2 has a cavity 3, and a driving assembly is disposed within the cavity 3. The driving assembly includes a rocker arm 6, a gear set, and a rack plate 7, such as... Figure 6 As shown, the mounting post 1 has two horizontal sliding grooves. A rack plate 7 is slidably disposed within these grooves, with one end extending beyond the end face of the mounting post 1 and the other end located within the cavity 3 of the mounting cylinder 2. The portions of the two rack plates 7 within the cavity 3 are fitted with racks 8, which are positioned opposite each other and mesh with a gear set. One gear in the gear set is fixedly connected to a rocker arm 6. The other end of the rocker arm 6 passes through the outer wall of the mounting cylinder 2 and is rotatably mounted. The rocker arm 6 is a conventional Z-shaped rocker arm, which requires less effort to rotate.

[0024] The gear set includes a drive gear 9, with a rocker arm 6 fixedly connected to its center. One end of the rocker arm 6 is rotatably mounted on the inner wall of the cavity 3, while the other end passes through the side wall of the cavity 3, providing support. The drive gear 9 meshes with a secondary gear 10, which rotates coaxially with a large gear 11. Specifically, the secondary gear 10 and the large gear 11 are fixedly mounted on the same shaft, with both ends of this shaft rotatably mounted on the inner walls of the two sides of the cavity 3.

[0025] The large gear 11 meshes with the rack plate 7, and simultaneously meshes with the small gear 12, which is attached to another rack plate 7. In use, the doctor shakes the rocker arm 6, which drives the drive gear 9 to rotate. The drive gear 9 drives the intermediate gear 10 to rotate, and the intermediate gear 10 coaxially drives the large gear 11 to rotate. The large gear 11 then drives the small gear 12 to rotate, causing both rack plates 7 to move simultaneously inward or outward.

[0026] Furthermore, the large gear 11 and the small gear 12 are also fixedly mounted on the rotating shaft, and the rotating shaft is rotatably mounted on the inner walls of both sides of the cavity 3 to support the gears.

[0027] Furthermore, the number of teeth on the drive gear 9 is less than that on the pinion 12, the number of teeth on the pinion 12 is less than that on the intermediate gear 10, and the number of teeth on the intermediate gear 10 is less than that on the large gear 11, which achieves a more labor-saving effect. Because the diameters of the gears in the gear set are different, the torque can be reduced while the transmission speed can be increased. This design is more labor-saving, improves work efficiency, reduces the physical exertion of medical staff, saves time, and reduces the pain and suffering of patients.

[0028] The other ends of the two rack plates 7 slide through the mounting post 1 and are connected to a rotating rod assembly via a spring 4. The rotating rod assembly includes a first Z-shaped rod 13 and a second Z-shaped rod 14. The ends of the first Z-shaped rod 13 and the second Z-shaped rod 14 are connected to the ends of the rack plates 7 via spring 4. A support rod 15 is fixedly installed at the outer end of the mounting post 1. A vertical plate 16 is integrally formed at the end of the support rod 15. The first Z-shaped rod 13 and the second Z-shaped rod 14 are rotatably installed at the ends of the vertical plate 16 and are located on both sides respectively.

[0029] Furthermore, the first Z-shaped rod 13 has several through holes 17, and the corresponding end of the vertical plate 16 has a through hole 17 of the same diameter. Bolts 18 are installed in the through holes to enable the rotation of the first Z-shaped rod 13. The second Z-shaped rod 14 has only one hole for rotational connection, that is, the Z-shaped rod 14 is rotated in place.

[0030] Both the ends of the first Z-shaped rod 13 and the second Z-shaped rod 14 are connected to arc-shaped simulated finger plates 5. The simulated finger plate 5 of the second Z-shaped rod 14 is larger than the simulated finger plate 5 connected to the first Z-shaped rod 13, and a C-shaped air cushion 19 is wrapped around the outer surface of the simulated finger plate 5 of the second Z-shaped rod 14.

[0031] The simulated finger plate structure of this invention is highly similar to the structure of medical staff's fingers, which can well simulate the structure of real fingers. In addition, a silicone layer is bonded to the surface, which can better fit the patient's skin and reduce the discomfort caused to the patient.

[0032] The No. 1 Z-shaped rod has several through holes. When in use, the different through holes of the No. 1 Z-shaped rod are connected to the vertical plate, so that the two Z-shaped rods have different torques and the adjustment force is also different. At the same time, the position distance of the simulated finger plate is adjusted, which can be better suited for the patient's coccyx repositioning. This avoids the situation where the size is not right, which would cause the simulated finger plate to not enter the proper position, and thus fail to accurately reposition the patient's coccyx.

[0033] A piston cylinder 20 is also provided at the end of the mounting column 1. An L-shaped piston rod 21 is installed inside the piston cylinder 20. The end of the piston rod 21 is fixedly mounted on the side wall of the rack plate 7. The piston cylinder 20 and the C-shaped air cushion 19 are connected by an air pipe. When the rack plate 7 moves inward, it drives the piston rod 21 to move into the piston cylinder 20, thus inflating the C-shaped air cushion 19. This increases the force of the C-shaped air cushion 19, achieving the repositioning of the patient's dislocated coccyx. The greater the lifting force of the repositioning device, the more fully the air cushion inflates, avoiding discomfort caused by hard contact between the simulated finger plate and the patient's body, greatly improving patient comfort.

[0034] A method for using a coccyx repositioning device: First, insert the C-shaped air cushion 19 into the patient's anus, ensuring it contacts the patient's misaligned coccyx. Then, manually crank the rocker arm 6. The rocker arm 6 drives the drive gear 9 to rotate, which in turn drives the intermediate gear 10. The intermediate gear 10 coaxially drives the large gear 11 to rotate, which in turn drives the small gear 12. The large gear 11 and small gear 12 simultaneously move the two rack plates 7 into the inner cavity 3, thus tightening the spring 4. This further causes the ends of the first Z-shaped rod 13 and the second Z-shaped rod 14 to move closer together. When the mounting column 1 moves in the direction of the movement, Z-shaped rod 13 and Z-shaped rod 14 rotate around the corresponding fulcrums on the vertical plate 16, bringing them closer together. Then, Z-shaped rod 14 pushes the fractured coccyx upwards, while Z-shaped rod 13 presses downwards at the external tail, thus achieving coccyx reduction. During this process, when the rack plate 7 moves inwards, it drives the piston rod 21 to move into the piston cylinder 20, thereby inflating the C-shaped air cushion 19 and increasing the pushing force of the C-shaped air cushion 19, which is beneficial for the reduction of the dislocated coccyx.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
