Abstract
Description
Technical Field
[0001] This invention relates to the field of spinal traction technology, and in particular to a traction stretching device for correcting scoliosis. Background Technology
[0002] Spinal traction, also known as spinal traction, is divided into several types depending on the patient's actual condition. One type allows the patient to lie in bed while traction is applied to the lower back and head.

During this process, uneven force can lead to poor patient comfort and treatment effect. Therefore, a lot of adjustments are required before traction. In addition, medical staff need to adjust the tension on time, making the operation of the entire traction process quite cumbersome. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0056] The following is combined with Figures 1 to 8 As shown, an embodiment of the present invention provides a traction and stretching device for scoliosis correction, comprising:
[0057] Support plate 1, with two symmetrical fixing components on its side wall;
[0058] Two tensioning components are provided at both ends of the support plate 1;
[0059] The tensioning components include:
[0060] Two L-shaped plates 2 are fixed to the top and bottom of the support plate 1 respectively, and each L-shaped plate 2 has a guide component rotatably installed on its side wall;
[0061] A rotating shaft 19 is rotatably positioned between two L-shaped plates 2.
[0062] The transmission seat 5 is fixedly sleeved on the rotating shaft 19. The top of the transmission seat 5 has multiple equally spaced fixing holes, and each fixing hole is equipped with a clutch assembly.
[0063] Two take-up reels 4 are rotatably mounted on the rotating shaft 19. Multiple round holes 20 are provided on the side wall of each take-up reel 4 near the transmission seat 5. The round holes 20 correspond one-to-one with the clutch assembly. The clutch assembly is used to cooperate with the round holes 20 to drive the take-up reel 4 to rotate.
[0064] When the clutch assembly is not in operation, the tension of the traction rope can be adjusted by the free rotation of the winding reel 4. In addition, by adjusting the guide assembly, the tension of each traction rope can be made uniform, thereby ensuring that the force acting on the patient in all directions is uniform during the subsequent traction process, so as to ensure the traction effect.
[0065] When the clutch assembly is working, the rotation of the transmission seat 5 can drive the winding reel 4 to rotate, thereby achieving tensioning and traction of the traction rope without the need for medical personnel to make adjustments.
[0066] Furthermore, the fixing components include:
[0067] Fixing plate 7 is fixed to the side wall of support plate 1, and the side wall of fixing plate 7 is provided with a first threaded hole.
[0068] The screw 8 is connected to the first threaded hole via a thread. One end of the screw 8 is fixed with a first knob, and the other end of the screw 8 is rotatably connected to an extrusion plate 9.
[0069] When installing this device, place the protruding part of the hospital bed between the support plate 1 and the compression plate 9. Then, rotate the first knob to drive the screw 8 to rotate, which, in conjunction with the first threaded hole, brings the compression plate 9 closer to the support plate 1, thereby fixing the device and the hospital bed.
[0070] Furthermore, the clutch assembly includes:
[0071] Cylinder 24, which is fixed inside the mounting hole;
[0072] Two second pistons 28 are slidably disposed inside the cylinder 24;
[0073] Spring 29 is fixed between the two second pistons 28;
[0074] Two transmission rods 25 are fixed to two second pistons 28 respectively, and the two transmission rods 25 pass through the top and bottom of the cylinder 24 respectively. The transmission rods 25 are adapted to the circular hole 20.
[0075] Furthermore, the tensioning assembly also includes:
[0076] The annular pipe 17 has multiple connecting pipes fixed on it, and the multiple connecting pipes are connected to the multiple cylinders 24 one-to-one.
[0077] Solenoid valve 18 is installed through the annular pipe 17.
[0078] Furthermore, an annular groove 22 is provided on the side wall of the winding reel 4 near the transmission seat 5, and multiple rubber sheets 23 are fixed on the inner wall of the annular groove 22 at equal intervals.
[0079] In an emergency, the solenoid valve 18 can be switched on, allowing the cylinder 24 to connect to the outside world through the connecting pipe, the annular pipe 17, and the solenoid valve 18. Under the action of the spring 29, the transmission rod 25 is driven to descend. Due to the limited tension of the spring 29, the top of the transmission rod 25 comes into contact with the rubber sheet 23. Under the friction between the transmission rod 25 and the rubber sheet 23, the winding reel 4 is prevented from rotating rapidly, thus preventing the traction rope from loosening suddenly and causing injury to the patient.
[0080] Furthermore, the tensioning assembly also includes:
[0081] Sleeve 21 is connected to annular tube 17, and a second threaded hole is provided at the top of sleeve 21.
[0082] The first piston 27 is slidably disposed inside the sleeve 21;
[0083] The lead screw 26 is rotatably mounted on the top of the first piston 27. The lead screw 26 passes through the second threaded hole, and a second knob is fixed to the top of the lead screw 26.
[0084] By rotating the second knob, which engages with the second threaded hole, the lead screw 26 gradually moves into the sleeve 21. During this process, the first piston 27 descends, injecting the gas in the sleeve 21 into each cylinder 24 through the annular pipe 17 and the connecting pipe. Through the action of the two second pistons 28 in the cylinder 24, the transmission rod 25 can pass through the round hole 20 on the take-up reel 4, thereby achieving the fixation between the take-up reel 4 and the transmission seat 5.
[0085] Furthermore, the guiding components include:
[0086] Adjusting plate 6 is rotatably mounted on the side wall of L-shaped plate 2;
[0087] Rod 13 is fixed to the end of the adjusting plate 6, and a ball head 14 is fixed to the end of the rod 13;
[0088] The seat 15 has a spherical groove on its side wall, and the ball head 14 is rotatably disposed in the spherical groove.
[0089] Guide ring 16 is fixed on base 15.
[0090] Furthermore, the guiding components also include:
[0091] Electric push rod 12, with connecting blocks 11 provided at both the end and the telescopic end of electric push rod 12;
[0092] Two connecting seats 10, one of which is fixed to the top of the support plate 1 and the other is fixed to the bottom of the adjusting plate 6, and the two connecting blocks 11 and the two connecting seats 10 are rotatably connected one-to-one.
[0093] When the switch of the electric push rod 12 is turned on, the electric push rod 12 rotates between the two sets of connecting seats 10 and connecting blocks 11, causing the adjusting plate 6 to rotate, so that the traction rope can be further tensioned. Through the operation of the electric push rod 12, the tension of each traction rope is made uniform. During this process, the multi-angle rotation between the ball head 14 and the seat body 15 ensures that the bending angle of the traction rope is reduced, thereby avoiding excessive resistance between the traction rope and the guide ring 16, so as to avoid the traction rope breaking due to excessive tension.
[0094] Furthermore, motors 3 are fixed to the top of the two L-shaped plates 2 located above, and the output shafts of the two motors 3 are fixed to the two rotating shafts 19 respectively.
[0095] The specific working method is as follows: When performing traction and stretching, two sets of this equipment are first prepared and installed at the head and foot of the bed respectively. Then, the lower part of the patient is fixed with a headgear, and the four traction ropes on the headgear are passed through the four guide rings 16 at the head of the bed. The waist fixation belt is fixed around the patient's waist, and the four traction ropes of the waist fixation belt are passed through the four guide rings 16 at the foot of the bed respectively. The traction ropes are then fixed to the nearest winding reel 4. Adjustments are then made.
[0096] When installing this device, place the protruding part of the hospital bed between the support plate 1 and the compression plate 9. Then, rotate the first knob to drive the screw 8 to rotate, which, in conjunction with the first threaded hole, brings the compression plate 9 closer to the support plate 1, thereby fixing the device and the hospital bed.
[0097] When making adjustments, first ensure that each drive rod 25 is inside the cylinder 24 so that the take-up reel 4 can rotate freely. The rotation of the take-up reel 4 is used to tension the traction rope. After all the traction ropes are tensioned, turn the second knob to engage with the second threaded hole, so that the lead screw 26 gradually moves into the sleeve 21. During this process, the first piston 27 is driven to descend, and the gas in the sleeve 21 is injected into each cylinder 24 through the annular pipe 17 and the connecting pipe. Through the action of the two second pistons 28 in the cylinder 24, the drive rod 25 can pass through the round hole 20 on the take-up reel 4, thereby fixing the take-up reel 4 and the drive seat 5.
[0098] Since the lengths of the traction ropes are different, after restricting the rotation of the winding reel 4, the corresponding electric push rod 12 is switched on according to the condition of the traction rope. When the electric push rod 12 is working, the adjustment plate 6 is rotated by the rotation between the two sets of connecting seats 10 and connecting blocks 11, so that the traction rope can be further tensioned. Through the operation of the electric push rod 12, the tension of each traction rope is made uniform. During this process, the bending angle of the traction rope is reduced by the multi-angle rotation between the ball head 14 and the seat 15, thereby avoiding excessive resistance between the traction rope and the guide ring 16, so as to avoid the traction rope breaking when the tension is too high.
[0099] When performing traction work, the switch of motor 3 is turned on, and the motor 3 drives the rotating shaft 19 to rotate slowly. During the rotation of the rotating shaft 19, the transmission seat 5 is rotated. Then, through the cooperation of the cylinder 24, the transmission rod 25 and the round hole 20, the winding reel 4 is rotated, thereby realizing traction of the waist from four angles and traction of the head from four angles, so as to achieve uniform force during the traction process. When the tension reaches a certain level, the speed of motor 3 is changed to continuously wind up the traction rope at an extremely slow speed, so as to continuously increase the traction force, thereby eliminating the need for medical staff to frequently make adjustments.
[0100] During traction, when daily activities are required, the second knob can be rotated in the opposite direction to raise the first piston 27 of the rod, causing each transmission rod 25 to retract into the cylinder 24, thereby enabling the rewind reel 4 to rotate again. This facilitates the release of the headgear and waist fixation belt. In case of excessive tension or other emergency situations where the patient cannot tolerate it, the solenoid valve 18 can be switched on. The cylinder 24 can then be connected to the outside world through the connecting pipe, the annular pipe 17, and the solenoid valve 18. Under the action of the spring 29, the transmission rod 25 is driven to descend. Due to the limited tension of the spring 29, the top of the transmission rod 25 contacts the rubber sheet 23. Under the friction between the transmission rod 25 and the rubber sheet 23, the rewind reel 4 is prevented from rotating rapidly, thus preventing the traction rope from loosening suddenly and causing injury to the patient.
