[0002] The four-dimensional traction bed is a medical device designed based on modern rehabilitation medicine and biomechanical principles. It is mainly used for non-surgical treatment of spinal diseases. Its core is to simulate the physiological activity trajectory of the human spine through multi-dimensional and intelligent traction technology, and perform precise mechanical adjustments to the spine to achieve the purpose of relieving pain and improving spinal function.

[0003] At present, when the existing four-dimensional traction bed is used, when the patient is subjected to four-dimensional traction, the patient needs to lie on the traction bed, and then the patient's legs are fixed and suspended. However, during this process, the patient's legs are prone to cramps due to tension or pathological reasons, and the patient's legs cannot be put down immediately. Therefore, the patient will suffer too much discomfort.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-Figure 5 The present invention provides a technical solution: a minimally invasive spinal traction and reduction device for orthopedics, comprising a traction bed body 1, an emergency mechanism 2 is provided on the outside of the traction bed body 1, and a stretching mechanism 3 is provided above the traction bed body 1; The emergency mechanism 2 includes an emergency dropping unit 21 , which is disposed above the traction bed body 1 . The emergency dropping unit 21 can lower the patient's legs when the patient suffers from leg cramps.

[0023] As a further limitation of the emergency mechanism 2 of the present invention, the emergency drop unit 21 includes a rectangular frame 2103, the rectangular frame 2103 is arranged on the outside of the traction bed body 1, the inner wall of the rectangular frame 2103 is fixedly connected to a fixed frame 2108, the internal sliding connection of the fixed frame 2108 is connected to two sliding blocks 2119, the inner walls of the two sliding blocks 2119 are connected to the first roller 2116 by rotating together, the outer surface of the rectangular frame 2103 is fixedly connected to two return springs 2115, and one end of each return spring 2115 close to the sliding block 2119 is fixedly connected to the back of the sliding block 2119, and the two sliding blocks The side surfaces 2119 that are close to each other are fixedly connected with a connecting plate 2113, and the front of the connecting plate 2113 is fixedly connected with two limiting tooth plates 2114. A limiting gear 2109 is provided on the outer side of each limiting tooth plate 2114, and the outer surface of each limiting gear 2109 is engaged with the outer surface of the limiting tooth plate 2114. By setting up an emergency falling unit 21, the emergency falling unit 21 can be used to sense whether the patient has cramp problems, and use the thrust of the patient's legs subconsciously tightening when cramping, so that the connecting rope 2107 can be smoothly lowered, so that the patient's legs are lowered to a position flush with the patient.

[0024] See also Figure 3 and Figure 4 The outer surface of the traction bed body 1 is fixedly connected to a fixing frame 2106, and the inner wall of the fixing frame 2106 is rotatably connected to two short shafts 2105. The ends of the two short shafts 2105 close to each other are respectively fixedly connected to the two side surfaces of the rectangular frame 2103. The inner wall of the fixing frame 2108 is rotatably connected to the second roller 2117. By providing the fixing frame 2106 and the short shafts 2105, the fixing frame 2106 can be connected to the driving structure in the traction bed body 1, and can further drive the fixing frame 2106 to move, and the short shafts 2105 can make the rectangular frame 2103 rotate inside the fixing frame 2108.

[0025] See also Figure 1 and Figure 2The upper surface of the fixed frame 2106 is fixedly connected to two rectangular plates 2111. The inner walls of the two rectangular plates 2111 are connected to the long shaft 2112 for common rotation. The inner wall of each limiting gear 2109 is fixedly connected to the outer surface of the long shaft 2112. The outer surface of the long shaft 2112 is fixedly connected to two friction plates 2110. The side surfaces of the two friction plates 2110 that are away from each other are in contact with the side surfaces of the two rectangular plates 2111 that are close to each other. The outer surface of the long shaft 2112 is fixedly connected to the connecting rope 2107. The outer surfaces of the connecting rope 2107 are in contact with the outer surfaces of the first roller 2116 and the outer surfaces of the second roller 2117 respectively. The bottom end of the connecting rope 2107 is fixedly connected to the connecting frame 2104. By providing a rectangular plate 2111 and a long shaft 2112, the rectangular plate 2111 can provide support force to the long shaft 2112, so that the long shaft 2112 can rotate smoothly, and the friction plate 2110 fixed on the outer surface of the long shaft 2112 will contact the surface of the rectangular plate 2111, which can slow down the rotation rate of the long shaft 2112.

[0026] See also Figure 2-Figure 5 The right side of the traction bed body 1 is fixedly connected to a fixed tooth plate 2102, and the right side of the fixed frame 2106 is fixedly connected to a gear transmission 2101. The input end of the gear transmission 2101 is fixedly connected to a transmission gear 2120, and the outer surface of the transmission gear 2120 is engaged with the outer surface of the fixed tooth plate 2102. The output end of the gear transmission 2101 is fixedly connected to the right end of one of the short shafts 2105. Through the meshing relationship between the transmission gear 2120 and the fixed tooth plate 2102, when the transmission gear 2120 moves with the equipment, it can mesh with the fixed tooth plate 2102 and rotate. Through the speed change gear structure inside the gear transmission 2101, the short shaft 2105 can be driven to rotate, so that the rectangular frame 2103 is always parallel to the ground.

[0027] The specific implementation of this embodiment is as follows: when the device is needed, the patient is asked to lie on the traction bed body 1, and then the stepper motor 304 is controlled to run. Here, the medical staff needs to observe at all times. When the stepper motor 304 drives the stretching plate 302 to move to the position in contact with the patient's feet and the patient's feet obviously feel stretched, the stepper motor 304 can be controlled to stop running, and vice versa, the telescopic rod 305 is controlled to run. The telescopic rod 305 pushes the baffle 306 to move to the position in contact with the front of the positioning plate 308 and then stops running. Then the stepper motor 304 can be reset. Subsequently, the medical staff can tie up the patient's legs and hang them on the connecting frame 21. 04, and then the medical staff can control the driving structure in the traction bed body 1 to adjust the position of the rectangular frame 2103 and the fixed frame 2106. It should be understood here that the fixed frame 2106 is fixed to the driving structure in the traction bed body 1, but the rectangular frame 2103 is not fixed to the fixed frame 2106, but is rotatably connected to the inner wall of the fixed frame 2106. Therefore, the rectangular frame 2103 can be rotated. When the driving structure in the traction bed body 1 is displaced to drive the fixed frame 2106 and the rectangular frame 2103 to adjust their positions, the transmission gear 2120 will engage with the surface of the fixed tooth plate 2102. Therefore, the transmission gear 2120 will rotate, and the transmission gear 2120 will rotate. 0 will transmit power to the gear transmission 2101, and through the gear transmission structure inside the gear transmission 2101, the power will eventually be transmitted to the short shaft 2105, driving the short shaft 2105 and the rectangular frame 2103 to rotate. Therefore, it can always ensure that the rectangular frame 2103 is parallel to the ground. Therefore, the connecting rope 2107 inside the rectangular frame 2103 is always perpendicular to the ground. The patient is lying on the traction bed body 1 at this time, so the patient's legs are in a bent state. When the patient's legs cramp, the patient will subconsciously straighten their legs. Therefore, when the patient straightens his legs, the connecting rope 2107 will move toward the direction of the first roller 2116, thereby pushing the first roller 2 116. The sliding block 2119 and the connecting plate 2113 move backward, and during the movement, they will drive the limit gear plate 2114 to stop engaging with the limit gear 2109. Therefore, the long shaft 2112 is not subject to any limiting force at this time. Under the action of gravity, the connecting rope 2107 will move downward, thereby driving the long shaft 2112 to rotate. When the long shaft 2112 rotates, the friction plate 2110 fixed on the surface of the long shaft 2112 will contact the surface of the rectangular plate 2111. The friction force can slow down the rotation rate of the long shaft 2112, preventing the problem of the connecting rope 2107 and the connecting frame 2104 moving downward quickly due to the long shaft 2112 rotating too fast, causing the patient's leg to be injured.

[0028] Example 2: Please refer to Figure 1 、 Figure 6-Figure 8The present invention provides a technical solution: a minimally invasive spinal traction and reduction device for orthopedics. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The emergency mechanism 2 also includes an emergency stop unit 22. The emergency stop unit 22 is arranged above the traction bed body 1. The emergency stop unit 22 can automatically stop when the patient feels discomfort in the spine.

[0029] As a further limitation of the emergency mechanism 2 of the present invention, the emergency stop unit 22 includes a fixed plate 2202, the bottom surface of the fixed plate 2202 is fixedly connected to the outer surface of the traction bed body 1, the upper surface of the fixed plate 2202 is fixedly connected to a rectangular box 2201, the interior of the rectangular box 2201 and the interior of the fixed plate 2202 are slidably connected to two handles 2205, the bottom surface of each handle 2205 is fixedly connected to a push plate 2212, and a limit plate 2213 is provided above each push plate 2212. The outer surface of 2213 is slidably connected to the interior of the rectangular box 2201, the inner wall of the rectangular box 2201 is rotatably connected to the rotating shaft 2211, the left end of the rotating shaft 2211 is fixedly connected to the rotating plate 2210, and the outer surface of the rotating shaft 2211 is fixedly connected to the flip plate 2209. By setting up the emergency stop unit 22, the emergency stop unit 22 can be used to ensure that when the patient is undergoing spinal traction, if he feels uncomfortable due to pathological or psychological reasons, the traction action can be stopped urgently without asking for help from the staff, thereby reducing the length of time the patient endures pain.

[0030] See also Figure 6 and Figure 7 , the back of each handle 2205 is fixedly connected to a force spring 2206, and the end of each force spring 2206 away from the handle 2205 is fixedly connected to the outer surface of the rectangular box 2201, and a movable plate 2203 is arranged above the fixed plate 2202, and the inner wall of the movable plate 2203 is fixedly connected to a hydraulic rod 2204, and the hydraulic rod 2204 is arranged in the inner cavity of the rectangular box 2201, and the telescopic end of the hydraulic rod 2204 is in contact with the front of the flip plate 2209. By providing the hydraulic rod 2204, the thrust generated by the hydraulic rod 2204 during operation can act on the flip plate 2209, but the flip plate 2209 cannot rotate. Therefore, under the action of the reaction force, the hydraulic rod 2204 will push the movable plate 2203 to move forward.

[0031] See also Figure 8The bottom surface of the fixed plate 2202 is fixedly connected to a support block 2215, and both side surfaces of the support block 2215 are provided with a first T-shaped groove 2217. The interior of each first T-shaped groove 2217 is slidably connected to a first T-shaped slider 2216, and the sides of the two first T-shaped sliders 2216 that are away from each other are fixedly connected to the sides of the two push plates 2212 that are close to each other. The bottom surface of each limit plate 2213 is fixedly connected to a bull's eye bearing 2214, and the outer surface of each bull's eye bearing 2214 is in contact with the outer surface of the push plate 2212.

[0032] See also Figure 6 Two second T-shaped slots 2208 are provided on the upper surface of the fixed plate 2202, and each second T-shaped slot 2208 is slidably connected to a second T-shaped slider 2207. The upper surface of each second T-shaped slider 2207 is fixedly connected to the bottom surface of the movable plate 2203. By providing the first T-shaped slider 2216 and the first T-shaped slot 2217, the position of the push plate 2212 can be limited. Similarly, the second T-shaped slider 2207 slides inside the second T-shaped slot 2208 to limit the position of the movable plate 2203.

[0033] The specific implementation of this embodiment is as follows: when traction is performed on the patient's spine, the patient's back needs to be fixed on the movable plate 2203, the patient's buttocks need to be fixed on the fixed plate 2202, and the patient's palms need to hold the two handles 2205 tightly, and then the hydraulic rod 2204 is controlled to operate. The operation of the hydraulic rod 2204 will apply a thrust to the flip plate 2209. At that time, the back of the flip plate 2209 contacts the front of the limit plate 2213, so the flip plate 2209 cannot rotate smoothly. Under the action of the reaction force, the movable plate 2203 will be pushed forward, thereby achieving the purpose of traction of the patient's spine. If the patient feels uncomfortable during traction, the patient will subconsciously apply thrust to the two handles 2205, wanting to push the lower body forward. When the patient applies thrust to the handles 2205, the handles 2205 will push the push plate 2212 backward. When the push plate 2212 moves backward, the groove part of the push plate 2212 will not contact the outer surface of the bull's eye bearing 2214, and the groove part of the push plate 2212 is made of a magnet. Under the dual action of magnetism and gravity, the limit plate 2213 will be pulled downward, so that the limit plate 2213 no longer contacts the surface of the flip plate 2209. At this time, the flip plate 2209 is not restricted by any force, so the flip plate 2209 will flip around the rotating shaft 2211 under the action of the thrust of the hydraulic rod 2204. Therefore, the operation of the hydraulic rod 2204 will not generate a reaction force at this time, so it will no longer push the movable plate 2203 to move forward, and the traction of the patient can be stopped. It should be understood here that the surface of the limit plate 2213 is coated with a coating that reduces friction. Therefore, the limit plate 2213 can move downward smoothly under the action of gravity and magnetism.

[0034] Example 3: Please refer to Figure 1 and Figure 9 The present invention provides a technical solution: a minimally invasive spinal traction and reduction device for orthopedics. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The stretching mechanism 3 can perform emergency stretching on the patient's cramped legs.

[0035] As a further limitation of the stretching mechanism 3 of the present invention, the stretching mechanism 3 includes two square boxes 301, the bottom surface of each square box 301 is fixedly connected to the upper surface of the fixed plate 2202, the upper surface of each square box 301 is provided with a rectangular opening 303, the interior of each rectangular opening 303 is slidably connected to a transverse plate 309, the upper surface of each transverse plate 309 is fixedly connected to the stretching plate 302, the inner wall of each square box 301 is fixedly connected to a stepper motor 304 and two telescopic rods 305, the telescopic end of each telescopic rod 305 is fixedly connected to a baffle 306, and each stepper motor 304 is fixedly connected to the inner wall of each square box 301. The output ends are fixedly connected with threaded shafts 307, the inner walls of each transverse plate 309 are threadedly connected to the outer surface of the threaded shaft 307, and the front of each transverse plate 309 is fixedly connected with a positioning plate 308. By setting up a stretching mechanism 3, the stretching mechanism 3 can automatically stretch the patient's legs to speed up the end of the cramp state. By setting up an emergency falling unit 21, an emergency stop unit 22 and a stretching mechanism 3, it can effectively avoid the problem that when the equipment is in use, the patient is prone to discomfort due to his own pathology or emotional tension, and seeking help from the above will waste a certain amount of time, which increases the patient's pain time.

[0036] The specific implementation of this embodiment is as follows: when the patient's leg cramps and he or she puts down, the patient's toes, feet and legs will all be subconsciously in a tense state, and at this time, the stepper motor 304 will run to drive the threaded shaft 307 to rotate. By utilizing the threaded connection between the threaded shaft 307 and the transverse plate 309, the threaded shaft 307 and the stretching plate 302 can be driven to move toward the patient's foot. Therefore, under the action of external force, a thrust can be provided to the lower half of the patient's foot, so that the patient's leg tendons can be in a straightened state. It should be understood here that since the patient has controlled the telescopic rod 305 to push the baffle 306 to a suitable position before treatment, when the stretching plate 302 moves to a position where the patient can be stretched, the positioning plate 308 will also contact the surface of the baffle 306. Therefore, the positioning plate 308 at this time will limit the transverse plate 309 and the stretching plate 302 from continuing to move forward, which can effectively prevent the stretching plate 302 from overstretching the patient's leg and causing secondary injury.
