Description

Technical Field

[0001] The invention relates to the technical field of orthopedics, in particular to a multifunctional orthopedic traction device. Background Art

[0002] Bone traction is a method of treating bone injuries such as fractures or joint dislocations. It helps to reposition and heal bones by applying force to partially or completely separate the bones. Bone traction can be implemented through external or internal devices. This treatment method needs to be carried out under the guidance of a doctor and may take some time to achieve the desired effect. Because the broken ends of the bones are like a knife, relatively fixing the broken ends of the bones will damage the surrounding muscles, nerves or blood vessels and cause unnecessary secondary injuries, so bone traction is very important; bone traction can pull the broken ends of the bones apart and reduce local bleeding after pulling them apart. Because most fractures require surgical treatment, it creates very good conditions for surgery. During surgery, after the local relative stability of the broken ends of the bones, it will greatly improve the convenience of surgical operations, which is very important for the future recovery of limb function. Therefore, for comminuted fractures, displaced fractures, and severe fractures, bone traction is a very necessary treatment measure When performing bone traction on a patient, the traction force applied to the patient is generally calculated according to the patient's weight, but the weights of different patients are not exactly the same, and the existing equipment for providing gravity is often a fixed-weight weight.

In this device, the patient's diseased limb is placed separately, and the inclination angle of the diseased limb is slowly adjusted by the pneumatic push rod to avoid discomfort to the patient, and the angle component can display the final inclination angle of the thigh board. The nurse can adjust the height of the sliding frame according to the displayed angle, so that the traction direction is consistent with the angle of the patient's leg lifting, so that all traction force can be applied to the patient's leg.

[0005] Furthermore, the pre-tensioning component includes a rotating wheel, a motor 1, an electric push rod, a clamp and a spring 1. The rotating wheel is rotatably connected to the top of the fixed frame through a bracket, the motor 1 is fixedly connected to the side of the rotating wheel bracket, the output end of the motor 1 passes through the bracket and is fixedly connected to the side of the rotating wheel, the electric push rod is fixedly connected to the inner wall of the rotating wheel, the clamp is rotatably connected to the output end of the electric push rod, and the two ends of the spring 1 are respectively fixedly connected to both sides of the inner wall of the clamp, and the pre-tensioning mechanism clamps the pull rope with the clamp and rotates the pull rope to make it tight, thereby solving the problem of the pull rope being loose when adjusting the angle.

[0006] Furthermore, the arc plate is slidably connected to the bottom of the calf plate, the pneumatic push rod is located directly below the calf plate, and a scale is opened on the side of the side plate at the position of the pointer.

[0008] Furthermore, the water outlet component includes a hose, a second motor, a rotating frame and a water receiving trough, the hose is fixedly connected to the water outlet of the water pump, the end of the hose away from the water pump passes through the inner wall of the support frame and extends to the outside, the second motor is fixedly connected to the inner wall end face of the support frame, the rotating frame is fixedly connected to the output end of the second motor, and the water receiving trough is provided on the side of the support frame. In order to prevent the water in the hose from falling into the water bucket when the water pump stops, the water outlet component uses the rotating frame to wrap the hose, and after the hose becomes shorter, the water inside it will be squeezed out by the rotating frame and fall into the water receiving trough.

When the bone traction needs to be stopped urgently, motor three drives the cam to squeeze the movable splint. After being squeezed, the movable splint approaches the fixed splint, thereby fixing the pull rope, and as the sliding plate slides along the limit rod, the movable splint has an upward tendency due to the pulling of spring two. Therefore, when the pull rope is clamped, the movable splint will push the pull rope upward for a distance, thereby providing a buffer for the emergency stop of the pull rope, thereby avoiding secondary injury to the patient due to sudden pulling during the emergency stop.

[0010] Furthermore, the supporting component includes a limiting column, a supporting box, a fine-adjusting screw, a worm gear and a worm, the limiting column is fixedly connected to the top of the base, the bottom of the supporting box is sleeved and slidably connected to the side of the limiting column, the fine-adjusting screw penetrates and is threadedly connected to the bottom inner wall of the supporting box, the bottom of the fine-adjusting screw is rotatably connected to the top of the base, the worm gear is sleeved and fixedly connected to the bottom of the side of the fine-adjusting screw, the worm is fixedly connected to the top of the base through a bracket and meshes with the worm gear.

[0011] Furthermore, the part of the hose located inside the support frame is located inside the rotating frame, and the cam is slidably connected to the side of the moving clamp away from the second spring when rotating, and the hose is located above the bucket when water is flowing.

[0012] The present invention provides a multifunctional orthopedic traction device, which has the following beneficial effects: 1. A multifunctional orthopedic traction device is provided with a water outlet component. In the counterweight mechanism, a water pump transports water to a water bucket, and then the water bucket and the weight together constitute the weight required for bone traction. Since the amount of water can be continuously adjusted, the weight of the water bucket can be adjusted steplessly. In order to prevent the water in the hose from falling into the water bucket when the water pump stops, the water outlet component uses a rotating frame to wrap the hose. After the hose becomes shorter, the water inside the hose will be squeezed out by the rotating frame and fall into the inside of the water receiving trough, thereby avoiding water splashing to other parts of the device and preventing the residual water in the hose from flowing into the water bucket, resulting in excessive weight of the water bucket.

[0013] 2. This multifunctional orthopedic traction device is provided with an emergency stop component. Accidents are prone to occur to patients during bone traction. If the traction is not stopped in time, the patient's fixed head will be damaged. The existing traction frame lacks an emergency stop component. When the bone traction needs to be stopped urgently, the motor three drives the cam to squeeze the movable splint. After being squeezed, the movable splint approaches the fixed splint, thereby fixing the pull rope, and as the sliding plate slides along the limit rod, the movable splint has an upward tendency due to the pulling of the spring two. Therefore, when the pull rope is clamped, the movable splint will push the pull rope upward for a distance, thereby providing a buffer for the emergency stop of the pull rope, thereby avoiding secondary injury to the patient due to sudden pulling during the emergency stop.

[0014] 3. This is a multifunctional orthopedic traction device, which is provided with a supporting component. After the water bucket is filled, the traction weight cannot be changed, and the supporting component adjusts the traction weight by offsetting part of the gravity of the water bucket through the supporting force of the supporting box. Therefore, the doctor can use the supporting component to make a secondary adjustment to the traction weight according to the actual feeling of the patient after the water bucket is filled with water, and before traction, the supporting box can be used to support the bottom of the water bucket, thereby avoiding discomfort to the patient caused by the sudden weight generated during traction.

[0015] 4. This is a multifunctional orthopedic traction device, which is provided with an angle component. In order to prevent the patient's normal limbs from colliding with the diseased limbs, in the device, the patient's diseased limb is placed separately, and the pneumatic push rod slowly adjusts the inclination angle of the diseased limb to avoid discomfort to the patient. The angle component can display the final inclination angle of the thigh board. The nurse can adjust the height of the sliding frame according to the displayed angle, so that the traction direction is consistent with the angle of the patient's leg lifting, so that all traction force can be applied to the patient's legs.

[0016] 5. This multifunctional orthopedic traction device is provided with a pre-tightening component. When the sliding frame is adjusted according to the indication of the angle component, the pull rope is preferably kept in a taut state. The adjustment of the sliding frame must be performed before the traction begins, so the pull rope is in a loose state. The pre-tightening mechanism clamps the pull rope with a clamping claw and rotates the pull rope to make it taut, thereby solving the problem of the pull rope being loose when adjusting the angle.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0020] For the first embodiment, please refer to Figure 1 The present invention provides a technical solution: a multifunctional orthopedic traction device, comprising a bed body 1, a base 11 is fixedly connected to the side of the bed body 1, a universal wheel 12 is fixedly connected to the bottom of the base 11, a side plate 13 is fixedly connected to the side of the base 11, a column 14 is fixedly connected to the top of the base 11, a pulley 15 is rotatably connected to the top of the column 14, a side vertical plate 16 is fixedly connected to the side of the base 11 away from the side plate 13, a sliding frame 18 is slidably connected to the side of the column 14, a fixed frame 19 is also fixedly connected to the side of the column 14, the sides of the sliding frame 18 and the fixed frame 19 are both rotatably connected to the pulley 15, a tilting mechanism 2 is fixedly connected to the top of the side plate 13, a counterweight mechanism 3 is fixedly connected to the top of the base 11, and a pull rope 17 is rollingly connected to the outer wall of the pulley 15.

[0021] When in use, the patient lies on the bed and places the fractured leg on the thigh board 21 of the tilting mechanism 2. After adjustment by the pneumatic push rod 22, traction work can be performed. During traction, the pull rope 17 is first passed through the pulley 15 of the fixed frame 19 and the column 14, and then the pull rope 17 is passed through the bottom of the pulley 15 of the sliding frame 18, and then the height of the sliding frame 18 is adjusted by using the tilting mechanism 2 to change the traction angle of the pull rope 17. After the adjustment is completed, add an appropriate amount of water to the water bucket 33 and start traction.

[0022] For the second embodiment, please refer to Figure 2-Figure 5 The present invention provides a technical solution: the tilting mechanism 2 includes a thigh plate 21, a pneumatic push rod 22, an arc plate 23, a spring telescopic rod 24, a calf plate 25, an angle component 26 and a pre-tightening component 27. The thigh plate 21 is rotatably connected to the inner wall of the side plate 13, the pneumatic push rod 22 is rotatably connected to the bottom of the inner wall of the side plate 13, the output end of the pneumatic push rod 22 is rotatably connected to the side of the thigh plate 21, the arc plate 23 is fixedly connected to the side of the thigh plate 21, the spring telescopic rod 24 is fixedly connected to the bottom of the inner wall of the side plate 13, the calf plate 25 is fixedly connected to the output end of the spring telescopic rod 24, the angle component 26 is rotatably connected to the inner wall of the side plate 13, and the pre-tightening component 27 is fixedly connected to the top of the fixing frame 19.

[0023] After the patient places the thigh on the thigh board 21 and the calf on the calf board 25, the pneumatic push rod 22 is started. The output end of the pneumatic push rod 22 squeezes the thigh board 21 upward and sideways, and the thigh board 21 rotates after being squeezed. When the thigh board 21 rotates, the arc board 23 presses against the bottom of the calf board 25 and lifts the calf board 25 upward, so that the calf board 25 adapts to the changes of the thigh board 21.

[0024] The angle component 26 includes an arc groove 261, a sliding column 262, a connecting rod 263, a rotating rod 264 and a pointer 265. The arc groove 261 is opened on the inner wall of the side plate 13, the sliding column 262 is slidably connected to the inner wall of the arc groove 261 and fixedly connected to the side of the thigh plate 21, one end of the connecting rod 263 is sleeved and rotatably connected to the side of the sliding column 262, the rotating rod 264 is rotatably connected to the end of the connecting rod 263 away from the sliding column 262 through the connecting plate, the rotating rod 264 passes through the inner wall of the side plate 13 and is fixedly connected to the side of the pointer 265, and the pointer 265 is slidably connected to the side of the side plate 13.

[0025] When in use, the thigh plate 21 drives the sliding column 262 to slide in the arc groove 261, and the sliding column 262 drives the connecting rod 263 to move, and the connecting rod 263 drives the rotating rod 264 to rotate, and finally the rotating rod 264 drives the pointer 265 to rotate. The scale indicated by the pointer 265 is the gripping angle of the thigh plate 21.

[0026] The pre-tightening component 27 includes a rotating wheel 271, a motor 272, an electric push rod 273, a clamp 274 and a spring 275. The rotating wheel 271 is rotatably connected to the top of the fixed frame 19 through a bracket. The motor 272 is fixedly connected to the side of the rotating wheel 271 bracket. The output end of the motor 272 passes through the bracket and is fixedly connected to the side of the rotating wheel 271. The electric push rod 273 is fixedly connected to the inner wall of the rotating wheel 271. The clamp 274 is rotatably connected to the output end of the electric push rod 273. The two ends of the spring 275 are respectively fixedly connected to the two sides of the inner wall of the clamp 274. The arc plate 23 is slidably connected to the bottom of the calf plate 25. The pneumatic push rod 22 is located directly below the calf plate 25. The side of the side plate 13 is provided with a scale at the position of the pointer 265.

[0027] When in use, the nurse uses the scale indicated by the pointer 265 to adjust the height of the sliding frame 18. The nurse first fixes the pull rope 17 to the patient's leg, and then starts the electric push rod 273. The output end of the electric push rod 273 pulls the clamping claw 274 toward the inside of the rotating wheel 271 and generates a restoring force. The side of the clamping claw 274 is pulled by the rotating wheel 271 and clamps the pull rope 17. At the same time, the spring 1 275 contracts and generates a restoring force due to the pressure of the clamping claw 274. Then the motor 1 272 drives the rotating wheel 271 to rotate slightly. After the rotating wheel 271 rotates, the pull rope 17 is pulled. After being pulled, the pull rope 17 is slightly straightened. At this time, the nurse adjusts the pull rope 17 according to the pressure of the clamping claw 274. The height of the sliding frame 18 is adjusted by the angle indicated by the pointer 265. If the pull rope 17 becomes loose due to the change in the coverage of the sliding frame 18, the rotating wheel 271 is continuously controlled to rotate, thereby solving the problem of the pull rope 17 becoming loose when adjusting the angle, until the angle between the pull rope 17 and the surface of the bed body 1 and the lifting angle of the thigh board 21 are the same, then the adjustment can be stopped, and then the electric push rod 273 is controlled to push out the clamping claw 274, which loses the squeezing of the inner wall of the rotating wheel 271 after being pushed out, and then the spring three pushes the clamping claw 274 open, and the pull rope 17 is released, so that the traction direction of the pull rope 17 is consistent with the lifting angle of the patient's legs, avoiding the waste of traction force.

[0028] For the third embodiment, please refer to Figure 6-Figure 9 The present invention provides a technical solution: the counterweight mechanism 3 includes a water tank 31, a water pump 32, a water bucket 33, a water outlet component 34, an emergency stop component 35, a support component 36 and a support frame 37. The water tank 31, the water pump 32 and the support frame 37 are all fixedly connected to the top of the base 11, the water inlet of the water pump 32 is connected to the bottom of the water tank 31 through a pipeline, the water outlet of the water pump 32 is connected to the top of the side of the support frame 37 through a pipeline, the water bucket 33 is fixedly connected to one end of the pull rope 17 close to the counterweight mechanism 3, the water outlet component 34 is fixedly connected to the inner wall of the support frame 37, the emergency stop component 35 is fixedly connected to the side of the side vertical plate 16, and the support component 36 is fixedly connected to the top of the base 11.

[0029] After the tilting mechanism 2 is adjusted, water can be added to the water bucket 33. The water pump 32 transports the water in the water bucket 33 to the hose 341 through the pipeline, and then flows into the bucket through the hose 341. As the amount of water transported increases, the weight of the water bucket 33 begins to increase until the weight reaches the required level. The water pump 32 can be stopped, and then the water bucket 33 can be slowly lowered using the supporting component 36 to start traction. Since the amount of water can be continuously adjusted, the weight of the water bucket 33 can be adjusted steplessly.

[0030] The water outlet component 34 includes a hose 341, a second motor 342, a rotating frame 343 and a water receiving trough 344. The hose 341 is fixedly connected to the water outlet of the water pump 32. The end of the hose 341 away from the water pump 32 passes through the inner wall of the support frame 37 and extends to the outside. The second motor 342 is fixedly connected to the inner wall end face of the support frame 37. The rotating frame 343 is fixedly connected to the output end of the second motor 342. The water receiving trough 344 is opened on the side of the support frame 37.

[0031] During use, after the water pump 32 stops supplying water, a small amount of water still remains in the hose 341. In order to prevent this water from flowing into the water bucket 33, the motor 342 controls the rotating frame 343 to rotate, and the two ends of the rotating frame 343 wrap the hose 341. Then the hose 341 becomes shorter, and the water inside it is squeezed out and falls into the water receiving trough 344, thereby avoiding water splashing onto the rest of the device and preventing the remaining water in the hose 341 from flowing into the water bucket 33, causing the water bucket 33 to be overweight.

[0032] The emergency stop component 35 includes a limit rod 351, a fixed clamping plate 352, a sliding plate 353, a movable clamping plate 354, a spring 2 355, a blocking rod 356, a motor 357 and a cam 358. The limit rod 351 is fixedly connected to the side of the side vertical plate 16, the fixed clamping plate 352 is fixedly connected to the end face of the limit rod 351, the sliding plate 353 is sleeved and slidably connected to the side of the limit rod 351, the movable clamping plate 354 is hinged to the side of the sliding plate 353 through a connecting rod, the two ends of the spring 2 355 are respectively fixedly connected to the sides of the sliding plate 353 and the movable clamping plate 354, the blocking rod 356 is fixedly connected to the side of the movable clamping plate 354, the motor 357 is fixedly connected to the top of the side vertical plate 16, and the cam 358 is fixedly connected to the output end of the motor 357.

[0033] During use, when the patient suddenly feels uncomfortable during the traction process, the nurse can use the emergency stop component 35 to stop the traction. First, the motor three 357 is controlled to start, driving the cam 358 to rotate. The cam 358 squeezes the sliding plate 353 while rotating. The sliding plate 353 slides in the limit rod 351 and pushes the movable clamp 354 toward the fixed clamp 352. After the movable clamp 354 and the fixed clamp 352 clamp the pull rope 17, the movable clamp 354 rotates slightly upward under the pull of the spring two 355, and the sliding plate 353 continues to slide. The movable clamp 354 drives the pull rope 17 to slide upward under the push of the sliding plate 353, thereby the part of the pull rope 17 from the emergency stop component 35 to the patient becomes loose, thereby avoiding secondary injury to the patient due to sudden pulling during the emergency stop.

[0034] The supporting component 36 includes a limiting column 361, a supporting box 362, a fine-tuning screw 363, a worm gear 364 and a worm 365. The limiting column 361 is fixedly connected to the top of the base 11, the bottom of the supporting box 362 is sleeved and slidably connected to the side of the limiting column 361, the fine-tuning screw 363 penetrates and is threadedly connected to the bottom inner wall of the supporting box 362, the bottom of the fine-tuning screw 363 is rotatably connected to the top of the base 11, the worm gear 364 is sleeved and fixedly connected to the bottom of the side of the fine-tuning screw 363, the worm 365 is fixedly connected to the top of the base 11 through a bracket and meshes with the worm gear 364, the part of the hose 341 located inside the supporting frame 37 is located inside the rotating frame 343, the cam 358 is slidably connected to the side of the moving clamp 354 away from the spring 2 355 when rotating, and the hose 341 is located above the bucket 33 when water is flowing.

[0035] When in use, the support box 362 is first supported on the bottom of the bucket 33. After the bucket 33 is filled with water, the worm 365 is rotated, and the worm 365 drives the worm wheel 364 to rotate, and the worm wheel 364 drives the fine-tuning screw 363 to rotate. Driven by the thread of the fine-tuning screw 363, the support box 362 begins to move downward. During this period, the supporting force of the support box 362 partially offsets the gravity of the bucket 33, and the traction weight can also be adjusted for the second time. The slow descent of the support box 362 avoids the discomfort caused to the patient by the sudden weight generated during traction.

[0036] The patient lies on the bed and places the fractured leg on the thigh board 21 of the tilting mechanism 2. After adjustment by the pneumatic push rod 22, traction work can be performed. During traction, the pull rope 17 is first passed through the pulley 15 of the fixed frame 19 and the column 14, and then the pull rope 17 is passed through the bottom of the pulley 15 of the sliding frame 18, and then the height of the sliding frame 18 is adjusted by using the tilting mechanism 2 to change the traction angle of the pull rope 17. After the adjustment is completed, add an appropriate amount of water to the water bucket 33 and start traction.

[0037] After the patient places the thigh on the thigh board 21 and the calf on the calf board 25, the pneumatic push rod 22 is started. The output end of the pneumatic push rod 22 squeezes the thigh board 21 to the side and upward, and the thigh board 21 rotates after being squeezed. When the thigh board 21 rotates, the arc board 23 presses against the bottom of the calf board 25 and lifts the calf board 25 upward. The thigh board 21 drives the sliding column 262 to slide in the arc groove 261, and the sliding column 262 drives the connecting rod 263 to move, and the connecting rod 263 drives the rotating rod 264 to rotate. Finally, the rotating rod 264 drives the pointer 265 to rotate, and the scale indicated by the pointer 265 is the rotation angle of the thigh board 21.

[0038] The nurse uses the scale indicated by the pointer 265 to adjust the height of the sliding frame 18. The nurse first fixes the pull rope 17 to the patient's leg, and then starts the electric push rod 273. The output end of the electric push rod 273 pulls the clamping claw 274 toward the inside of the rotating wheel 271 and generates a restoring force. The side of the clamping claw 274 is pulled by the rotating wheel 271 and clamps the pull rope 17. At the same time, the spring 1 275 contracts and generates a restoring force due to the pressure of the clamping claw 274. Then the motor 1 272 drives the rotating wheel 271 to rotate slightly. After the rotating wheel 271 rotates, the pull rope 17 is pulled. The pull rope 17 is After being pulled, it is slightly straightened. At this time, the nurse adjusts the height of the sliding frame 18 according to the angle indicated by the pointer 265. If the pull rope 17 is loose due to the change in the coverage of the sliding frame 18, the rotating wheel 271 will continue to be controlled to rotate, thereby solving the problem of the pull rope 17 being loose when adjusting the angle, until the angle between the pull rope 17 and the surface of the bed body 1 and the lifting angle of the thigh board 21 are the same, then the adjustment can be stopped, and then the electric push rod 273 is controlled to push the clamp 274 out. After the clamp is pushed out, it loses the squeezing of the inner wall of the rotating wheel 271, and then the spring three pushes the clamp 274 open, and the pull rope 17 is released.

[0039] After the tilting mechanism 2 is adjusted, water can be added to the water bucket 33. The water pump 32 transports the water in the water bucket 33 to the hose 341 through the pipeline, and then flows into the bucket through the hose 341. As the amount of water transported increases, the weight of the water bucket 33 begins to increase. Until the weight reaches the requirement, the water pump 32 can be stopped, and then the water bucket 33 is slowly lowered using the supporting component 36, and traction can begin. After the water pump 32 stops supplying water, a little water still remains in the hose 341. In order to prevent this part of water from flowing into the water bucket 33, the motor 342 controls the rotating frame 343 to rotate, and the two ends of the rotating frame 343 wrap the hose 341. Then the hose 341 becomes shorter, and the water inside it is squeezed out and falls into the water receiving trough 344.

[0040] When the patient suddenly feels uncomfortable during the traction process, the nurse can use the emergency stop component 35 to stop the traction. First, the motor three 357 is controlled to start, driving the cam 358 to rotate. The cam 358 squeezes the sliding plate 353 while rotating. The sliding plate 353 slides in the limit rod 351 and pushes the movable clamping plate 354 toward the fixed clamping plate 352. After the movable clamping plate 354 and the fixed clamping plate 352 clamp the pull rope 17, the movable clamping plate 354 rotates slightly upward under the pull of the spring two 355, and the sliding plate 353 continues to slide. The movable clamping plate 354 drives the pull rope 17 to slide upward under the push of the sliding plate 353.

[0041] The support box 362 is first supported on the bottom of the water bucket 33. After the water is added to the water bucket 33, the worm 365 is rotated, and the worm 365 drives the worm wheel 364 to rotate, and the worm wheel 364 drives the fine-tuning screw 363 to rotate. Driven by the thread of the fine-tuning screw 363, the support box 362 begins to move downward, during which the supporting force of the support box 362 partially offsets the gravity of the water bucket 33.
