Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to a radius fracture reducer. Background Art

[0002] The radius and ulna are important components of the human forearm. The radius is close to the thumb, and the ulna is close to the thumb. Distal radius fracture is one of the most common fracture types, that is, a fracture occurs at the end of the patient's upper limb close to the wrist, usually caused by landing on the palm of the hand when falling. When a patient has a radius fracture, bone setting techniques are usually used for reduction. First, the fracture site needs to be fully stretched and pulled to fully separate the fracture ends, relieve the shortening deformity, and restore the length of the bone ends. The traction operation needs to be performed by two medical personnel, the surgeon and the assistant, such as Figure 1 As shown, the patient lies on a treatment bed 9 with the shoulder extended 90° and the elbow flexed 90°. An assistant pulls the patient's elbow while the surgeon pulls the patient's palm. While applying traction, the surgeon applies techniques such as lifting, pressing, and compressing the fracture to restore it to its correct position. After reduction, a cotton pad is wrapped around the fracture, and small splints are placed around the patient's upper limb. These splints are then secured with bandages, keeping the patient's wrist fixed at a specific angle to maintain the reduction.

[0003] In the related art, the patent with publication number CN211834914U discloses a distal radius fracture manual reduction assist device, which includes a support platform and a traction assembly. A first lifting adjustment rod is provided on the support platform, and two mutually meshing brake racks are provided on the first lifting adjustment rod, one of which is fixed and the other is slidable. An elbow joint fixer is provided on the fixed brake rack, and a palm fixer is provided on the sliding rack, which are used to fix the patient's elbow joint and palm respectively. The traction assembly is used to drive the palm fixer to slide along the brake rack. The doctor can pull the patient's radius fracture by operating the traction assembly.

[0004] In view of the above-mentioned related technologies, the inventors found that the reduction assistive device can enable a doctor to complete the traction operation for patients with radial fractures, saving medical resources. However, the reduction assistive device has the following problems: 1. During manual reduction, the patient usually lies on the examination bed with the shoulder abducted 90°. If the assistive device is used, the patient's shoulder needs to be abducted 180° to fit the setting of the elbow joint fixator and the palm fixator. Such a setting is obviously not in line with the physiological curve of the human body. If the assistive device is used flat, the device will 1. It will interfere with the patient's body and is inconvenient to use; 2. During the traction process using the auxiliary device, the patient's fracture is fixed in the palm fixator. If the doctor wants to perform a reduction technique on the patient during the traction process, he cannot do so and can only open the palm fixator to perform the operation, which is quite inconvenient and affects the reduction efficiency; 3. Although the traction process can be completed by one doctor, a medical staff member is still needed to help fix the four small splints when tying them subsequently, and the surgeon will then tie the small splints. In fact, it does not achieve the effect of saving medical resources. Summary of the Invention

[0005] In order to solve the above problems, the present application provides a radius fracture reducer.

[0006] The present application provides a radial fracture reducer that adopts the following technical solution: A radius fracture reducer comprises a horizontally arranged movable bracket, wherein a seat and a support box are provided on the movable bracket, and the two are spaced apart along the length direction of the movable bracket, and an arm airbag clamping assembly and a hand airbag clamping assembly are provided on the support box, wherein the hand airbag clamping assembly is located between the arm airbag clamping assembly and the seat, and the arm airbag clamping assembly can slide in a direction away from the seat, and the hand airbag clamping assembly is fixed on the support box, wherein the arm airbag clamping assembly is used to clamp the forearm of a patient with a radius fracture, and the hand airbag clamping assembly is used to clamp the hand of a patient with a radius fracture, and a pedal drive assembly is provided on the support box, wherein the pedal drive assembly is used to drive the arm airbag clamping assembly to slide.

[0007] By adopting the above technical solution, when reducing a patient's radial fracture, the patient is first asked to lie on the diagnosis and treatment bed, and the doctor pushes the movable bracket to the side of the patient's arm that needs to be reduced, so that the length direction of the movable bracket is parallel to the diagnosis and treatment bed, and then the patient's shoulder is abducted 90 degrees and the elbow is flexed 90 degrees, so that the patient's forearm that needs to be reduced is placed in the arm airbag clamping component, and the hand is placed in the hand airbag clamping component, and the patient's forearm and hand are fixed. The movable platform can be pushed to the side where the patient's arm is fractured. It is not only convenient to use, but also meets the standard posture of patients for radius fracture reduction. Even if the patient maintains a comfortable and standard reduction posture, it is convenient for the doctor to operate and improves the efficiency of diagnosis and treatment. After the airbag is inflated, the patient's forearm and hand are fixed. The doctor then sits on the chair and applies external force to the pedal drive assembly by pedaling. The pedal drive assembly drives the arm airbag clamping assembly to move away from the hand airbag clamping assembly. At the same time, during the traction process, the doctor can perform reduction techniques on the patient's wrist fracture, so that one person can achieve traction and reduction of the patient's radial fracture, greatly saving medical resources. At the same time, because the doctor applies external force to drive traction by pedaling, the doctor can adjust the intensity and time of the applied external force in real time according to the patient's response, so as to achieve the traction effect while avoiding excessive traction, thereby improving the diagnosis and treatment effect. After traction, the arm airbag clamp assembly can be deflated, a cotton pad can be wrapped around the patient's fracture, and then four small splints can be placed in the arm airbag clamp assembly, respectively located around the patient's wrist. The arm airbag clamp assembly is then inflated so that the four small splints fit the patient's arm. At this time, since the small splints are fixed, the doctor can complete the binding of the small splints by himself, without the need for an assistant to help hold the small splint, which further saves medical resources.

[0008] Optionally, the pedal drive assembly includes a first rotating shaft and a second rotating shaft, both of which are rotatably connected to the support box, the second rotating shaft is located above the first rotating shaft, both ends of the first rotating shaft extend out of the support box and are fixedly connected to a rotating rod, the length direction of the rotating rod is perpendicular to the axial direction of the first rotating shaft, the two rotating rods are arranged relative to each other with the plane where the axis of the first rotating shaft is located as a symmetrical plane, and pedals are rotatably connected to the two rotating rods, the first rotating shaft and the second rotating shaft are coaxially fixedly connected to pulleys, the two pulleys are connected by belts, and the second rotating shaft is coaxially fixedly connected to a gear, and a rack meshing with the gear is slidably connected to the support box, and the rack can drive the arm airbag clamping assembly to slide in a direction away from or close to the seat.

On the one hand, the doctor can achieve traction on the patient's fracture through this simple structure, achieving a labor-saving effect. One person can also perform the traction operation, improving the efficiency of diagnosis and treatment and saving medical resources; on the other hand, the doctor can adjust the intensity and time of the external force applied in real time according to the patient's reaction, so as to achieve the traction effect and avoid excessive traction, thereby ensuring the diagnosis and treatment effect; on the third hand, the doctor can perform a reduction technique on the patient's hand while stepping on the traction, that is, one person can complete the traction and reduction operations at the same time, improving the efficiency of diagnosis and treatment.

[0010] Optionally, a movable table is provided on the top of the support box, and a giveway groove is opened on the top of the support box, and the giveway groove is opened along the length direction of the movable bracket. The rack is slidably connected in the giveway groove and is fixedly connected to the bottom surface of the movable table through the giveway groove. The arm airbag clamping assembly is provided on the movable table, and an adjustment assembly is provided on the movable table. The length direction of the movable table is perpendicular to the length direction of the movable bracket, and the adjustment assembly is used to drive the arm airbag clamping assembly to slide along the length direction of the movable table.

[0011] By adopting the above technical solution, after the patient lies on the treatment bed, the movable bracket is pushed to the side where the patient's fractured arm is located, and then the position of the arm airbag clamping assembly is adjusted left and right through the adjustment component to make it close to the treatment bed, so that the patient can place his forearm in the arm airbag clamping assembly in a comfortable posture, which conforms to the physiological curve of the human body and reduces the patient's discomfort during the diagnosis and treatment process.

[0012] Optionally, the adjusting assembly includes an adjusting screw, the axial direction of the adjusting screw is parallel to the length direction of the movable table, two fixed boxes are fixedly connected to the movable table, the adjusting screw is rotatably connected between the two fixed boxes, one end of the adjusting screw extends into a fixed box and is coaxially fixedly connected to a first bevel gear, and the fixed box is also rotatably connected to a second bevel gear, the first bevel gear and the second bevel gear are meshed, and a connecting rod is coaxially fixedly connected to the second bevel gear, the connecting rod extends out of the movable platform and is fixedly connected to a rotating handle, the arm airbag clamping assembly includes an arm clamping box and an airbag arranged in the arm clamping box, the adjusting screw passes through the bottom of the arm clamping box and is threadedly connected to it.

[0013] By adopting the above technical solution, the first bevel gear and the second bevel gear can be driven to rotate by rotating the handle, the second bevel gear drives the adjusting screw to rotate, and the adjusting screw drives the arm clamping box to slide left and right, so that the position of the arm clamping box can be adjusted to be close to the side of the patient's fractured arm, thereby completing the adjustment of the arm clamping box position, and the operation is simple and convenient.

[0014] Optionally, the hand airbag clamping assembly includes a hand clamping plate and an airbag arranged in the hand clamping plate, the arm clamping box is provided with a slide groove on the side facing the hand clamping plate, the hand clamping plate is provided with a connecting plate on the side facing the arm clamping box, the connecting plate extends into the slide groove, the slide groove is opened along the length direction of the movable bracket, the top of the support box is fixedly connected to a fixed platform, and the hand clamping plate is connected to the fixed platform by sliding axially along the adjusting screw.

[0015] By adopting the above technical solution, since the hand clamping plate and the arm clamping box are connected by the connecting plate, when the position of the arm clamping box is adjusted left and right, the hand clamping plate can be driven to slide left and right at the same time, so that the two always remain coaxial, while not affecting the forward and backward movement of the arm clamping box, thereby improving the efficiency of adjusting the traction position left and right and ensuring the accuracy of fixing the patient's forearm and hand.

[0016] Optionally, three airbags are provided in the arm clamping box, and an air pump is provided in the support box. The air pump inflates or deflates the three airbags through a gas pipe. The length direction of the arm clamping box is parallel to the length direction of the movable bracket. The top surface and both ends of the arm clamping box are open, and the three airbags are respectively located on the bottom surface and the vertical sides inside the arm clamping box.

[0017] By adopting the above technical solution, after the patient places the forearm in the arm clamp box, the three air bags are inflated or deflated by the air pump to complete the clamping or release of the patient's forearm, which not only facilitates clamping but also improves the comfort of clamping for the patient.

[0018] Optionally, an elastic band is bonded to both ends of the top surface of the arm clamping box in the width direction, and the two elastic bands are used to clamp the cotton pad.

[0019] By adopting the above technical solution, the cotton pad is clamped at the top opening of the arm clamp box by two elastic bands. When the patient puts his arm into the arm clamp box from top to bottom, the cotton pad is brought into the arm clamp box and wrapped around the outside of the patient's forearm. At this time, the airbag is inflated, and the airbag bulges to make the cotton pad fit the patient's forearm, and then the traction operation is performed. On the one hand, the patient's arm can be separated from the airbag to maintain hygiene after use by different patients; on the other hand, it prepares for the subsequent doctor to fix the small splint, which can save the doctor the subsequent step of wrapping the cotton pad, reduce the doctor's workload, and improve the efficiency of diagnosis and treatment.

[0020] Optionally, the hand clamping plate is configured to be U-shaped, and two airbags are provided in the hand clamping plate, and the two airbags are respectively located on both vertical sides of the hand clamping plate.

[0021] By adopting the above technical solution, the doctor can control the degree of inflation or deflation of the airbag by controlling the time of pressing the inflation button or the deflation button. Therefore, when fixing the small splint, the doctor can press the deflation button to partially deflate the airbag, leaving some space between the patient's arm and the arm clamp box, making it easier to insert the small splint. After vacuuming, the doctor first adjusts the cotton pad on the patient's arm so that it fits tightly against the patient's skin. Then, he places the small splints that fix the sides and bottom of the patient's arm between the patient's forearm and the air bag in contact with it. Finally, he places the small splint that fixes the top of the patient's arm on top. Since the small splints are fixed by the air bag at this time, there is no need for an assistant to hold the small splint. Therefore, the doctor can complete the strapping and fixing operation of the small splint alone, which further saves medical resources.

[0022] Optionally, the mobile bracket includes two support rods and a telescopic rod, the telescopic rod is fixedly connected between the two support rods, the seat and the support box are respectively arranged at both ends of the telescopic rod, and a first locking bolt is provided on the telescopic rod, and the first locking bolt is used to lock the telescopic rod.

[0023] By adopting the above technical solution, the distance between the seat and the support box can be adjusted by the telescopic rod, and then the telescopic rod is locked by the first locking bolt, so that the space suitable for the operation of different doctors can be adjusted according to their body shapes, which is convenient for different doctors to use and expands the scope of application of the reducer.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. After the airbag is inflated, the patient's forearm and hand are fixed. The doctor then sits on a chair and applies external force to the pedal drive assembly by pedaling. The pedal drive assembly drives the arm airbag clamping assembly away from the hand airbag clamping assembly. At the same time, during the traction process, the doctor can perform reduction manipulation on the patient's wrist fracture. This allows one person to achieve traction and reduction of the patient's radial fracture, greatly saving medical resources. In addition, because the doctor applies the external force by pedaling, the doctor can adjust the intensity and duration of the applied external force in real time according to the patient's response, achieving the desired traction effect while avoiding excessive traction, thereby improving the diagnosis and treatment effect. 2. After traction, the arm airbag clamp assembly can be deflated, a cotton pad can be wrapped around the patient's fracture, and four small splints can be placed inside the arm airbag clamp assembly, one around the patient's wrist. The arm airbag clamp assembly is then inflated again, so that all four small splints fit the patient's arm. Since the small splints are now fixed, the doctor can complete the binding of the small splints alone, without the help of an assistant to hold the small splint, further saving medical resources. 3. After the patient lies on the examination bed, push the mobile bracket to the side where the patient's fractured arm is located. Then, adjust the position of the arm airbag clamp assembly left and right through the adjustment component, so that it is close to the examination bed. This allows the patient to place the forearm in the arm airbag clamp assembly in a comfortable posture that conforms to the physiological curve of the human body and reduces the patient's discomfort during the diagnosis and treatment process.

The movable platform 51 can drive the arm airbag clamping assembly 61 to move in a direction close to or away from the hand airbag clamping assembly 62, thereby achieving traction on the patient's radial fracture arm. An adjustment assembly 7 is also provided on the movable platform 51, which is used to drive the hand airbag clamping assembly 62 and the arm airbag clamping assembly 61 to slide in a horizontal direction perpendicular to the longitudinal direction of the movable bracket 1.

[0030] When reducing a patient's radial fracture, the patient is first placed on the examination bed 9. The doctor pushes the movable support 1 to the side of the patient's arm to be reduced, so that the length of the movable support 1 is parallel to the examination bed 9 and the support box 3 is located between the patient's fractured arm and the chair 2. The adjustment assembly 7 is then used to adjust the position of the hand airbag clamping assembly 62 and the arm airbag clamping assembly 61, so that they move closer to the examination bed 9. The patient's forearm to be reduced is then placed in the arm airbag clamping assembly 61 and the hand is placed in the hand airbag clamping assembly 62, thereby securing the patient's forearm and hand. The doctor then sits on the chair 2 and applies an external force to the pedal drive assembly 4 by pedaling. The pedal drive assembly 4 drives the movable platform 51 away from the fixed platform 52, thereby driving the arm airbag clamping assembly 61 away from the hand airbag clamping assembly 62, thereby achieving traction on the patient's radial fracture site. During the traction process, the doctor can simultaneously perform reduction techniques on the patient's wrist fracture. After traction, the arm airbag clamping assembly 61 can be deflated, and then four small splints can be placed in the arm airbag clamping assembly 61, respectively located around the patient's wrist. The arm airbag clamping assembly 61 is then inflated so that the four small splints all fit the patient's arm. The doctor then uses a strap to tie the four small splints, so that one person can complete the operation of reducing and fixing the patient's radial fracture, saving medical resources.

By rotating the handle 76, the first bevel gear 73 and the second bevel gear 74 can be driven to rotate, and the second bevel gear 74 can drive the adjusting screw 71 to rotate, and the adjusting screw 71 can drive the arm clamping box 611 to slide along the length direction of the movable platform 51, so that the position of the arm clamping box 611 can be adjusted to be close to the side where the fractured arm is located after the patient lies on the treatment bed 9, so as to enable the patient to maintain a suitable posture and clamp his forearm.

[0038] Reference Figure 4 and Figure 5 To facilitate simultaneous adjustment of the position of the hand clamping plate 621, a slide groove 77 is provided on the side of the arm clamping box 611 facing the hand clamping plate 621. A connecting plate 78 is fixedly connected to the side of the hand clamping plate 621 facing the arm clamping box 611. The connecting plate 78 extends into the slide groove 77. The slide groove 77 extends along the length of the arm clamping box 611. Therefore, when the arm clamping box 611 is moved axially along the adjustment screw, the hand clamping plate 621 can be simultaneously driven to slide. To facilitate guiding the hand clamping plate 621, a guide groove 521 is provided on the fixed platform 52 along the axial direction of the adjustment screw. The bottom of the hand clamping plate 621 is slidably connected to the guide groove 521.

[0039] The implementation principle of a radial fracture reducer in an embodiment of the present application is as follows: when reducing a patient's radial fracture, first let the patient lie on the treatment bed 9, the doctor pushes the movable bracket 1 to the side of the patient's arm that needs to be reduced, so that the length direction of the movable platform 51 is parallel to the treatment bed 9, and locks the movable bracket 1.

[0040] A cotton pad 8 is then clamped between the two elastic bands 617 to secure the pad 8. The handle 76 is then rotated, driving the first bevel gear 73 and the second bevel gear 74. The second bevel gear 74 then drives the adjustment screw 71, which in turn drives the arm clamping box 611 and the hand clamping plate 621 to slide near the examination bed 9, bringing them closer to the patient's fractured arm. The patient's shoulder is then abducted 90 degrees, pushing their forearm downward from above the cotton pad 8 into the arm clamping box 611, placing the middle of their hand within the hand clamping plate 621. The inflation button 631 is then activated, causing the air pump 614 to inflate the airbag 612, clamping the patient's forearm and hand. The doctor can control the inflation time and thus the clamping force according to the thickness of the patient's arm. During the inflation and clamping process, the cotton pad 8 is wrapped around the patient's forearm. On the one hand, it isolates each patient using the reducer and maintains hygiene. On the other hand, it saves the step of wrapping the cotton pad 8 when fixing the small splint later, making it easier for the doctor to operate.

[0041] To perform traction, the doctor sits on the chair 2 and steps on the pedal 43, which drives the first rotating shaft 41 to rotate. The first rotating shaft 41 drives the pulley 45 thereon to rotate. The pulley 45 drives another pulley 45 via a belt to rotate. The other pulley 45 drives the second rotating shaft 44 to rotate. The second rotating shaft 44 drives the gear 46 to rotate. The gear 46 drives the rack 47 to slide along the clearance groove 33. The rack 47 drives the mobile platform 51 to slide away from the chair 2. The mobile platform 51 drives the arm clamping box 611 to slide away from the chair 2, thereby tractioning the patient's fracture. During the traction process, the doctor can hold the patient's hand to reduce the fracture.

[0042] When traction and reduction are completed, the doctor can press the vacuum button 632 to partially vacuum the airbag 612, and then adjust the cotton pad 8 on the patient's arm to make it close to the patient's skin, and then clamp the small splints that fix the patient's arms on both sides and the bottom between the patient's forearm and the airbag 612 that is in contact with it, and then put the small splint that fixes the top of the patient's arm. Since the small splints are fixed by the airbag 612 at this time, the doctor can complete the strapping and fixing operation of the small splints alone.

[0043] After the small splint is fixed, the doctor can continue to press the air pump button 632 to fully deflate the airbag 612, so that the patient's arm can be removed. With this reducer, only one doctor is needed to complete the traction, reduction and fixation of the patient's radial fracture, which not only facilitates the doctor's reduction operation but also greatly saves medical resources.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
