Description

Technical Field

[0001] This invention relates to the field of bone injury traction technology, and more specifically, to an orthopedic trauma traction and stretching device. Background Technology

[0002] Orthopedic traction is a treatment method that uses external force to pull bones or joints to achieve repositioning, fixation, pain relief, or correction of deformities. It is commonly used for fractures, joint dislocations, and spinal diseases. Its core principle is to restore normal bone alignment and reduce tissue compression through continuous or intermittent mechanical action.

[0003] However, existing orthopedic trauma traction and stretching devices make it inconvenient to measure the length of a patient's limbs after skeletal traction. Medical staff need to use separate instruments to measure the length of the patient's limbs, which reduces the efficiency of medical staff and makes it impossible to maintain measurement accuracy. Summary of the Invention

[0004] This invention provides an orthopedic trauma traction and stretching device to solve the problem that existing orthopedic trauma traction and stretching devices make it inconvenient to measure the length of a patient's limbs after skeletal traction, requiring medical staff to use separate instruments to measure the length of the patient's limbs, which reduces the work efficiency of medical staff.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An orthopedic trauma traction and stretching device includes a base frame and a directional component. The base frame has a pair of side grooves at its bottom end and a pair of connecting sleeves on the base frame. A directional frame is rotatably engaged between the two connecting sleeves. One end of the directional frame is slidably engaged with an adjustment frame through a pair of slots. The directional component includes a pair of connecting frames fixedly connected to the outside of the adjustment frame. A distance-fixing groove is formed at the top of the connecting frame. One end of the distance-fixing groove is connected to a guide groove. The extension direction of the guide groove is the same as that of the directional frame and the adjustment frame.

[0007] Preferably, a winder is provided at one end of the base frame, and a pair of pull ropes are connected to the output end of the winder. A trapezoidal block is connected to the free end of each of the two pull ropes. A pair of trapezoidal slots are provided on the base frame, and the two trapezoidal blocks are slidably locked in the two trapezoidal slots respectively. A push plate is connected to the top of each trapezoidal block.

[0008] Preferably, side buttons are provided on both sides of the orientation frame, and one side of the push plate contacts the outer side of the side button.

[0009] Preferably, a folding pad is provided between the adjusting frame and the directional frame, and a limiting plate is provided at the bottom of the adjusting frame, the limiting plate protruding outward.

[0010] Preferably, a puncture needle is slidably mounted in the guide groove, one end of the puncture needle is threaded through a first disinfection bottle, a connecting plate is provided at the free end of the puncture needle, a pair of connecting blocks are hinged to the outside of the connecting plate, the two connecting blocks are connected by a second disinfection bottle, and the cap of the second disinfection bottle is located on the outside of the connecting blocks.

[0011] Preferably, a pair of pull rings are sleeved on the outside of the puncture needle, and a directional block is connected to the outside of each of the two pull rings. The two directional blocks are slidably locked in the two guide grooves, and the two pull rings are fixedly connected to each other. The two pull rings are connected to a load plate through a load rope.

[0012] Preferably, the base frame is provided with a pair of columns, each of the two columns has a groove, and each of the two grooves has a slider that is slidably engaged, and the two sliders are connected by a first connecting rod.

[0013] Preferably, the two sliders are connected to a movable frame on their outer sides. A second connecting rod is provided on the movable frame. Guide wheels are rotatably connected to both the first and second connecting rods. The load rope is clamped on the outer side of the guide wheels.

[0014] Preferably, a fixing rod is slidably engaged on each of the two columns, and a connecting groove is provided at one end of the fixing rod. Sliding buttons are provided on both sides of the adjusting frame, and the sliding buttons are slidably engaged in the connecting groove.

[0015] Preferably, the two fixed rods are connected by multiple support straps, which are made of elastic material and have gaps between each support strap.

[0016] The principle and beneficial effects of this technical solution:

[0017] (1) The orientation component set in this invention can keep the direction of traction of the puncture needle parallel to the orientation frame. On the one hand, it can make the load rope of the traction puncture needle traction the tibial tuberosity of the patient in the correct direction. On the other hand, it can make the distance of the patient's tibial tuberosity traction by the load rope equivalent to the distance of the load plate connected to the free end of the load rope in the vertical direction, thereby reducing the workload of medical staff.

[0018] After adjusting the angle of the orientation frame, slide the distance adjustment frame along the orientation frame to expand the folding pad until the total length of the distance adjustment frame and the orientation frame is equivalent to the patient's thigh. At this point, puncture can be performed at the patient's traction site. Remove the first sterilization bottle inserted at one end of the puncture needle, then insert the puncture needle into the distance groove on either side and into the patient's body until it comes out. After inserting the end of the puncture needle into another distance groove, reinsert the first sterilization bottle into the free end of the puncture needle, while keeping the second sterilization bottle in the covered state with the connecting block.

[0019] (2) The column set in this invention can help medical staff adjust the traction direction of the load rope, improve the traction effect and facilitate the direct measurement of the traction distance. When the traction direction of the load rope needs to be parallel to the orientation frame, the slider slides along the groove opened in the column, so that the first connecting rod connected between the two sliders drives the moving frame and the second connecting rod to move in the vertical direction. Since the load rope is stuck on the outside of the guide wheel that is rotatably connected to the first connecting rod and the second connecting rod, the movement of the moving frame will drive the load rope to change the traction direction.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0027] Example:

[0028] like Figures 1 to 5As shown, the present invention provides an orthopedic trauma traction and stretching device, including a base frame 4 and a directional component. The bottom end of the base frame 4 has a pair of side grooves 1, and a pair of connecting sleeves 21 are provided on the base frame 4. A directional frame 20 is rotatably engaged between the two connecting sleeves 21. One end of the directional frame 20 is slidably engaged with an adjusting frame 10 through a pair of slots 18. The directional component includes a pair of connecting frames 15 fixedly connected to the outside of the adjusting frame 10. A distance-fixing groove 9 is provided at the top of the connecting frame 15. One end of the distance-fixing groove 9 is connected to a guide groove 12. The extension direction of the guide groove 12 is the same as that of the directional frame 20 and the adjusting frame 10.

[0029] like Figure 1 and Figure 4 As shown, a winder 27 is provided at one end of the base frame 4. A pair of pull ropes 22 are connected to the output end of the winder 27. Trapezoidal blocks 24 are connected to the free ends of the two pull ropes 22. A pair of trapezoidal grooves 28 are provided on the base frame 4. The two trapezoidal blocks 24 are slidably locked in the two trapezoidal grooves 28 respectively. A push plate 23 is connected to the top of the trapezoidal blocks 24.

[0030] like Figure 4 As shown, side buttons 19 are provided on both sides of the orientation frame 20, and one side of the push plate 23 contacts the outer side of the side button 19.

[0031] like Figure 3 and Figure 4 As shown, a folding pad 11 is provided between the adjusting frame 10 and the directional frame 20, and a limiting plate 16 is provided at the bottom of the adjusting frame 10, with the limiting plate 16 protruding outward.

[0032] like Figure 2 and Figure 3 As shown, a puncture needle 13 is slidably mounted in the guide groove 12. One end of the puncture needle 13 is threaded through a first disinfection bottle 5. A connecting plate 6 is provided at the free end of the puncture needle 13. A pair of connecting blocks 8 are hinged to the outside of the connecting plate 6. The two connecting blocks 8 are connected by a second disinfection bottle 7. The second disinfection bottle 7 is covered on the outside of the connecting blocks 8.

[0033] like Figures 3 to 5 As shown, a pair of pull rings 17 are sleeved on the outside of the puncture needle 13. Each of the two pull rings 17 is connected to a directional block 25. The two directional blocks 25 are slidably locked in the two guide grooves 12 respectively. The two pull rings 17 are fixedly connected to each other. The two pull rings 17 are connected to the load plate 37 through the load rope 31.

[0034] like Figure 1 and Figure 5 As shown, a pair of uprights 33 are provided on the base frame 4. Each of the two uprights 33 has a groove 32. Each of the two grooves 32 has a slider 30 that is slidably engaged. The two sliders 30 are connected by a first connecting rod 29.

[0035] like Figure 5As shown, the two sliders 30 are connected to a movable frame 34 on their outer sides. A first connecting rod 35 is provided on the movable frame 34. Guide wheels 36 are rotatably connected to both the first connecting rod 29 and the second connecting rod 35. The load rope 31 is clamped on the outer side of the guide wheel 36.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, a fixing rod 2 is slidably mounted on each of the two columns 33. A connecting groove 26 is provided at one end of the fixing rod 2. Sliding buttons 14 are provided on both sides of the adjusting frame 10. The sliding buttons 14 are slidably mounted in the connecting groove 26.

[0037] like Figure 1 As shown, the two fixed rods 2 are connected by multiple support straps 3. The support straps 3 are made of elastic material, and there are gaps between each support strap 3.

[0038] The column 33 helps medical staff adjust the traction direction of the load rope 31, improving the traction effect and facilitating direct measurement of the traction distance. When the traction direction of the load rope 31 needs to be parallel to the orientation frame 20, the slider 30 slides along the groove 32 opened inside the column 33, causing the first connecting rod 29 connecting the two sliders 30 to drive the moving frame 34 and the second connecting rod 35 to move vertically. Since the load rope 31 is locked on the outside of the guide wheel 36 rotatably connected to the first connecting rod 29 and the second connecting rod 35, the movement of the moving frame 34 will drive the load rope 31 to change the traction direction. At the same time, the fixed rod 2 slidably locked on the column 33 can support the patient's lower leg, and the support strap 3 set between the fixed rods 2 lifts the patient's lower leg, allowing the patient to undergo bone traction in a more comfortable state and improving the patient's medical experience.

[0039] The specific usage and function of this embodiment are as follows:

[0040] The directional component in this invention ensures that the traction direction of the puncture needle 13 is parallel to the directional frame 20. This allows the load rope 31 of the traction needle 13 to provide correct tibial tuberosity traction to the patient. Furthermore, it ensures that the distance the load rope 31 tractions on the patient's tibial tuberosity is equivalent to the vertical movement distance of the load plate connected to the free end of the load rope 31, thereby reducing the workload of medical staff. When using the device to perform tibial tuberosity traction on the patient, first place the patient's thigh on the side to be tractioned on the base frame 4 and the directional frame 20, which is rotatably secured by the connecting sleeve 21. Then, activate the winding device 27, causing it to pull a pair of pull ropes 22 connected to its output end. The pull ropes 22 pull the trapezoidal block 24 connected to their free ends. During the movement of the trapezoidal block 24, it will connect with its top end... The push plate 23 moves synchronously. Since one side of the push plate 23 is in contact with the outer side of the side buttons 19 on both sides of the orientation frame 20, the push plate 23 will drive the orientation frame 20 to rotate along the connecting sleeve 21 while moving. After the angle of the orientation frame 20 is adjusted, the adjusting frame 10 slides along the orientation frame 20 to make the folding pad 11 unfold until the total length of the adjusting frame 10 and the orientation frame 20 is equivalent to the patient's thigh. At this time, puncture can be performed at the patient's traction site. Remove the first disinfection bottle 5 inserted at one end of the puncture needle 13, and then insert the puncture needle 13 into the fixed distance groove 9 on either side and into the patient's body until it comes out. After inserting the end of the puncture needle 13 into another fixed distance groove 9, insert the first disinfection bottle 5 back into the free end of the puncture needle 13, while keeping the second disinfection bottle 7 in the covered state with the connecting block 8.

[0041] After the puncture is completed, slide the guide groove 12 along the fixed groove 9 until the guide groove 12 is flush with the puncture needle 13. Then, lock the two pull rings 17 on the outside of the puncture needle 13. After adjusting the traction direction of the load rope 31, the tibial tuberosity can be tractioned on the patient. By recording the displacement distance of the load plate in the vertical direction, the traction distance of the patient's tibial tuberosity can be understood simultaneously, thereby improving the work efficiency of medical staff.
