Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an orthopedic traction device. Background Technology

[0002] With the rapid development of society and economy, in the process of orthopedic surgery and treatment, it is often necessary to clamp and traction the bones of the human limbs to promote the treatment and rehabilitation of the human bones and achieve the goal of rapid recovery.

[0003] When using an orthopedic traction device, the distance between the two traction rods needs to be adjusted. One traction rod is fixed, while the other can move freely. After adjusting the distance between the two traction rods, the movable traction rod needs to be fixed. Generally, bolts are used to abut against a sliding rod to fix the traction rod. However, the bolts may loosen during use, which may cause the traction rod to shift and affect the normal progress of the surgery. Utility Model Content

[0004] This utility model is an orthopedic traction device proposed to solve the problem that when bolts are used to fix the tension rod, they may loosen during use, which may lead to displacement of the tension rod and affect the normal performance of the operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an orthopedic traction device, comprising a sliding rod, a slider slidably connected to the outer surface of the sliding rod, an auxiliary block and a stop block respectively fixedly connected to both ends of the sliding rod, a push block fixedly connected to the top of both the slider and the auxiliary block, anti-slip devices provided on both sides of the push block, a traction rod fixedly connected to the bottom of both the slider and the auxiliary block, an auxiliary frame detachably connected to the side of the two traction rods that are close to each other, a bolt threaded into the inner wall of the slider, an auxiliary device provided between the two traction rods, the auxiliary device comprising a first extension block, one side of the first extension block fixedly connected to the outer surface of the stop block, a second extension block fixedly connected to one side of the auxiliary block, the inner walls of the first extension block and the second extension block being provided with the same threaded rod, a screw hole block fixedly connected to the outer surface of the slider, and the outer surface of the threaded rod being threadedly connected to the outer surface of the threaded rod.

[0006] The effect achieved by the above components is as follows: by setting the threaded rod, rotating the threaded rod will drive the threaded hole block to move on the outer surface of the threaded rod. The threaded hole block will drive the slider to slide synchronously on the outer surface of the sliding rod until the tension rod connected to the slider reaches the appropriate position. Then, rotating the bolt will make one end of the bolt abut against the outer surface of the sliding rod, thus fixing the tension rod. The threaded rod can also provide auxiliary fixation between the slider and the sliding rod, which helps to prevent the tension rod from shifting and affecting the normal operation of the surgery.

[0007] Preferably, the outer surface of the threaded rod is fixedly connected to two bearings, and the outer surfaces of the two bearings are respectively fixedly connected to the inner walls of the first extension block and the second extension block.

[0008] The effect achieved by the above components is that by setting two bearings, the friction between the threaded rod and the first extension block and the second extension block can be reduced when rotating the threaded rod, making it easier to rotate the threaded rod.

[0009] Preferably, one end of the threaded rod passes through the inner wall of the second extension block and is fixedly connected to an operating block, the outer surface of which is provided with protrusions.

[0010] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0011] Preferably, the outer surface of the threaded rod is threaded with a nut, which is disposed between the first extension block and the threaded hole block.

[0012] The effect achieved by the above components is as follows: by setting the nut and rotating the nut so that one side of the nut abuts against one side of the screw hole block, the nut can limit the direction of the screw hole block away from the second extension block, thereby helping to prevent the two tension rods from moving too far apart, which would cause excessive stretching of the patient's extraosseous skin tissue and cause further damage to the patient.

[0013] Preferably, a rubber ring is fixedly connected to one side of the nut, and the outer surface of the threaded rod is disposed inside the rubber ring.

[0014] The effect achieved by the above-mentioned components is that by setting a rubber ring, one side of the nut can abut against one side of the screw hole block, and the friction between the nut and the screw hole block is increased, making the nut less likely to loosen.

[0015] Preferably, the anti-slip device includes two rubber strips, one side of which is uniformly provided with grooves, and the two sides of the push block are symmetrically provided with auxiliary grooves, and the outer surface of the rubber strips is inserted into the inner wall of the auxiliary grooves.

[0016] The effect achieved by the above components is as follows: by setting the rubber strip and inserting it into the inner wall of the auxiliary groove, the rubber strip and the push block can be fixed. The rubber strip with grooves can increase the friction on both sides of the push block, so that it has an anti-slip effect when operating the push block. In addition, the rubber strip is detachable, which makes it easy to clean and disinfect the rubber strip.

[0017] Preferably, both sides of the rubber strip are fixedly connected with a locking block, and both sides of the push block are symmetrically provided with locking grooves. Both locking grooves are connected to the inner wall of the auxiliary groove, and the outer surface of the locking block is inserted into the inner wall of the locking groove.

[0018] The effect achieved by the above-mentioned components is as follows: by setting the locking block and the locking slot, inserting the locking block into the inner wall of the locking slot can help fix the rubber strip and further prevent the rubber strip from detaching from the inner wall of the auxiliary slot.

[0019] Preferably, a pin is inserted into the inner wall of the card block, one end of the pin is fixedly connected to one side of the inner wall of the card slot, and a rubber block is fixedly connected to the outer surface of one end of the pin, the cross section of the rubber block being an isosceles trapezoid.

[0020] The effect achieved by the above-mentioned components is as follows: by setting a rubber block, one end of the rubber block is smaller, which makes it easier to insert the rubber block and the pin into the inner wall of the card block, while the other end of the rubber block is larger, which can limit the movement between the card block and the pin, thereby helping to prevent the card block from detaching from the inner wall of the card slot.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a threaded rod, the threaded hole block can drive the slider to slide synchronously on the outer surface of the sliding rod until the traction rod connected to the slider reaches the appropriate position. Then, the bolt is rotated to fix the traction rod and the sliding rod. The threaded rod can also provide auxiliary fixation between the slider and the sliding rod, which helps to prevent the traction rod from shifting and affecting the normal operation of the surgery.

[0029] Example 1, referring to Figures 1-4 As shown, this embodiment discloses an orthopedic traction device, including a sliding rod 1. A slider 4 is slidably connected to the outer surface of the sliding rod 1. An auxiliary block 5 and a stop block 9 are fixedly connected to both ends of the sliding rod 1, respectively. A push block 6 is fixedly connected to the top of both the slider 4 and the auxiliary block 5. Anti-slip devices 3 are provided on both sides of the push block 6. A traction rod 7 is fixedly connected to the bottom of both the slider 4 and the auxiliary block 5. An auxiliary frame 8 is detachably connected to the side of the two traction rods 7 that are close to each other. The auxiliary frame 8 can be disassembled and replaced with a suitable auxiliary frame 8 for different positions of the human skeleton. A bolt 10 is threaded into the inner wall of the slider 4. An auxiliary device 2 is provided between the two traction rods 7. The auxiliary device 2 includes a first extension block 21. One side of the first extension block 21 is fixedly connected to the outer surface of the stop block 9, and one side of the auxiliary block 5 is fixedly connected to... There is a second extension block 22. The inner walls of the first extension block 21 and the second extension block 22 are provided with the same threaded rod 23. The outer surface of the slider 4 is fixedly connected with a screw hole block 24. The outer surface of the threaded rod 23 is threadedly connected to the outer surface of the threaded rod 23. By setting the threaded rod 23, rotating the threaded rod 23 will drive the screw hole block 24 to move on the outer surface of the threaded rod 23. The screw hole block 24 will drive the slider 4 to slide synchronously on the outer surface of the sliding rod 1 until the traction rod connected to the slider 4 reaches the appropriate position. Then, the bolt 10 is rotated so that one end of the bolt 10 abuts against the outer surface of the sliding rod 1, which can fix the traction rod. The threaded rod 23 can provide auxiliary fixation between the slider 4 and the sliding rod 1, which helps to prevent the traction rod 7 from shifting and affecting the normal operation of the surgery.

[0030] Reference Figures 2-4As shown, two bearings 25 are fixedly connected to the outer surface of the threaded rod 23. The outer surfaces of the two bearings 25 are fixedly connected to the inner walls of the first extension block 21 and the second extension block 22, respectively. By setting two bearings 25, the friction between the threaded rod 23 and the first extension block 21 and the second extension block 22 can be reduced when rotating the threaded rod 23, making it easier to rotate the threaded rod 23. One end of the threaded rod 23 passes through the inner wall of the second extension block 22 and is fixedly connected to an operating block 26. The outer surface of the operating block 26 is provided with protrusions. By setting the operating block 26, rotating the operating block 26 can drive the threaded rod 23 to rotate. At the same time, the protrusions on the outer surface of the operating block 26 can effectively increase the friction on the outer surface of the operating block 26, which has an anti-slip effect when rotating the operating block 26.

[0031] Reference Figures 2-4 As shown, a nut 27 is threadedly connected to the outer surface of the threaded rod 23. The nut 27 is located between the first extension block 21 and the threaded hole block 24. By setting the nut 27 and rotating it, one side of the nut 27 abuts against one side of the threaded hole block 24. The nut 27 can limit the direction of the threaded hole block 24 away from the second extension block 22, which helps to prevent the two tension rods 7 from moving too far apart, thus preventing excessive stretching of the patient's extraosseous skin tissue and causing further damage to the patient. A rubber ring 28 is fixedly connected to one side of the nut 27. The outer surface of the threaded rod 23 is located inside the rubber ring 28. By setting the rubber ring 28, one side of the nut 27 can abut against one side of the threaded hole block 24 instead of the other side, and the friction between the nut 27 and the threaded hole block 24 can be increased, making the nut 27 less likely to loosen.

[0032] Reference Figure 2 and Figure 5 As shown, the anti-slip device 3 includes two rubber strips 31. Grooves are evenly provided on one side of the rubber strips 31, and auxiliary grooves 32 are symmetrically provided on both sides of the push block 6. The outer surface of the rubber strips 31 is inserted into the inner wall of the auxiliary grooves 32. By setting the rubber strips 31 and inserting them into the inner wall of the auxiliary grooves 32, the rubber strips 31 and the push block 6 can be fixed. The rubber strips 31 with grooves can increase the friction on both sides of the push block 6, so that the push block 6 has an anti-slip effect when operating. The rubber strips 31 are detachable, which makes it easy to clean and disinfect the rubber strips 31.

[0033] Reference Figure 2 and Figure 5As shown, both sides of the rubber strip 31 are fixedly connected with locking blocks 33, and both sides of the push block 6 are symmetrically provided with locking grooves 34. Both locking grooves 34 are connected to the inner wall of the auxiliary groove 32. The outer surface of the locking block 33 is inserted into the inner wall of the locking groove 34. By setting the locking block 33 and the locking groove 34, the rubber strip 31 can be auxiliaryly fixed by inserting the locking block 33 into the inner wall of the locking groove 34, further preventing the rubber strip 31 from detaching from the inner wall of the auxiliary groove 32. The inner wall of the locking block 33 is provided with a pin 3. 5. One end of the pin 35 is fixedly connected to one side of the inner wall of the slot 34. A rubber block 36 is fixedly connected to the outer surface of one end of the pin 35. The cross-section of the rubber block 36 is an isosceles trapezoid. By setting the rubber block 36, one end of the rubber block 36 is smaller, which makes it easier to insert the rubber block 36 and the pin 35 into the inner wall of the block 33. At the same time, the other end of the rubber block 36 is larger, which can limit the movement between the block 33 and the pin 35, thereby helping to prevent the block 33 from detaching from the inner wall of the slot 34.

[0034] Working principle: Rotating the operating block 26 drives the threaded rod 23 to rotate. The threaded rod 23 drives the threaded hole block 24 to move on the outer surface of the threaded rod 23. The threaded hole block 24 drives the slider 4 to slide synchronously on the outer surface of the sliding rod 1 until the tension rod connected to the slider 4 reaches the appropriate position. Then, rotating the nut 27 causes one side of the nut 27 to abut against one side of the threaded hole block 24. The nut 27 can limit the direction of the threaded hole block 24 away from the second extension block 22, which helps to prevent the two tension rods 7 from moving too far apart, thus preventing excessive stretching of the patient's extraosseous skin tissue and causing further damage to the patient. Rotating the bolt 10 causes one side of the bolt 10 to move away from the second extension block 22. When the end of the sliding rod 7 abuts against the outer surface of the sliding rod 1, the traction rod can be fixed. The threaded rod 23 can provide auxiliary fixation between the slider 4 and the sliding rod 1, which helps to prevent the traction rod 7 from shifting and affecting the normal operation of the surgery. When the rubber strip 31 is inserted into the inner wall of the auxiliary groove 32, and the locking block 33 is inserted into the inner wall of the locking groove 34, and the rubber block 36 and the pin 35 are inserted into the inner wall of the locking block 33, the rubber strip 31 and the push block 6 can be fixed. The rubber strip 31 with grooves can increase the friction on both sides of the push block 6, so that it has an anti-slip effect when operating the push block 6. The rubber strip 31 is detachable, which makes it easy to clean and disinfect the rubber strip 31.
