Technical Field

[0001] This utility model relates to the field of traction devices for leg fractures, and in particular to a traction device for leg fractures. Background Technology

[0002] A leg fracture traction device is a medical device used to treat leg fractures. It mainly uses traction force to align the fracture site and ensure that the bones maintain the correct alignment during fracture healing.

[0003] Currently, when hospitals perform traction treatment on fracture patients, the auxiliary devices mainly involve hanging a sandbag or other heavy object of a certain weight on the traction line and then placing it on a simple support to apply traction to the patient. This method cannot effectively control and adjust the traction force. The heavy object provides rigid traction adjustment when pulling, which can easily lead to over-adjustment of traction, causing secondary injury to the patient and affecting the efficiency of treatment. Utility Model Content

[0004] The technical problem this invention aims to solve is that, currently, when hospitals perform traction treatment on fracture patients, the auxiliary devices used mainly involve hanging a sandbag or other heavy object of a certain weight on the traction line and then placing it on a simple support to apply traction to the patient. This method cannot effectively control and adjust the traction force. The heavy object provides rigid traction adjustment during traction, which can easily lead to excessive traction adjustment, causing secondary injury to the patient and affecting treatment efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a leg fracture traction device, including a base plate, and a traction mechanism is provided on one side of the base plate. The traction mechanism can fix and limit the patient's leg on the slide and the fixing frame through the fixing component. Then, the threaded rod moves the threaded hole block to drive the slide to move and flexibly traction the patient's leg, thereby avoiding excessive traction and secondary injury.

[0006] Preferably, the traction mechanism includes a threaded rod, wherein the outer surface of one end of the threaded rod penetrates one side of the inner wall of the base plate, and a fixing frame is fixedly installed on one side of the base plate; a self-locking motor, wherein the output end of the self-locking motor is fixedly installed on one end of the threaded rod by means of a coupling, and one side is fixedly installed on one side of the base plate; a threaded block, wherein the inner wall of the threaded block is threaded onto the outer surface of the threaded rod, and one end is slidably connected to the inner wall of the base plate; a slide, wherein the inner wall of the slide is fitted onto the outer surface of the threaded rod, and one end is slidably connected to the inner wall of the base plate, and fixing components are provided on one side of the slide and one side of the fixing frame; two first telescopic rods, wherein the two ends of the first telescopic rods are respectively fixedly installed on one side of the threaded block and one side of the slide; and two first springs, wherein the inner wall of the first springs is fitted onto the outer surface of the first telescopic rods, and the two ends are respectively fixedly installed on one side of the threaded block and one side of the slide.

[0007] The aforementioned components achieve the following effects: By setting up a traction mechanism, when performing traction treatment on fracture patients, the injured leg can be fixed to the slide and fixation frame using a fixation component. Then, according to treatment needs, the self-locking motor is activated to drive the threaded rod to rotate, thereby causing the threaded block to slide to one end on the inner wall of the base plate. Then, under the pull of the first telescopic rod and the first spring, the slide can move to one end within the inner wall of the base plate. The first spring and the first telescopic rod will act as a buffer between the slide and the threaded frame, preventing the threaded block from moving too fast and causing excessive traction. This allows the slide to perform flexible traction according to the actual usage during the traction process, avoiding secondary injuries and improving treatment efficiency.

[0008] Preferably, the fixing component includes two straps, one end of which is fixedly installed on one side of the slide and the fixing frame respectively. Hook and loop fasteners are symmetrically fixedly installed on one side of the straps, and loop fasteners are symmetrically fixedly installed on one side of the straps. Square ring blocks are threaded through one side of both the slide and the fixing frame, and one end of the strap is inserted into the inner wall of the square ring block.

[0009] The effect achieved by the above components is as follows: by setting the fixing components, after the patient's leg is placed above the slide and the fixing frame, one end of the strap can be inserted into the inner wall of the square ring block, and then folded back, and the hook-and-loop fastener on one side can be attached to the loop fastener, so that the patient's leg can be tied and fixed on one side of the slide and the fixing frame, and the patient's leg can be limited and fixed.

[0010] Preferably, a protrusion is fixedly installed on one side of the square ring block, and a plurality of round holes are opened on one side of the strap, with one end of the protrusion inserted into the inner wall of the round hole.

[0011] The effect achieved by the above components is as follows: by setting the round holes and protrusions, when the strap is inserted into the inner wall of the square ring block and then folded back, the protrusions will be inserted into the corresponding round holes, which will initially fix and limit the strap, thereby improving the fixing effect of the strap.

[0012] Preferably, anti-slip blocks are fixedly installed on one side of both the carriage and the fixing frame, and the anti-slip blocks are made of rubber.

[0013] The effect achieved by the above components is that by setting anti-slip blocks, the contact friction between the slide and the fixing frame can be increased, making it more secure and stable when fixing the patient's leg.

[0014] Preferably, the base plate is symmetrically provided with adjustment limiting mechanisms on both sides. The adjustment limiting mechanism includes a limiting rod, one end of which is slidably connected to the inner wall of the base plate, and a plurality of locking holes are opened on one side of the limiting rod. Sliding grooves are symmetrically opened on both sides of the base plate; a locking block, one end of which is slidably installed in the inner wall of the sliding groove, and the other end is inserted into the inner wall of the locking hole; and a second spring, the two ends of which are respectively fixedly installed on one side of the locking block and one side of the inner wall of the sliding groove.

[0015] The effect achieved by the above-mentioned components is as follows: By setting an adjustment limiting mechanism, when it is necessary to install and fix the base plate on the hospital bed for use, the locking block can be manually slid to one end in the slide groove according to the width of the bed, causing the second spring to contract. Then, the limiting rod is pulled outward in the inner wall of the base plate to a certain position, so that one side of the limiting rod abuts against the edge of the hospital bed. At this time, the locking block is released, and under the reset action of the second spring, one end can be locked into the corresponding locking hole, fixing the adjusted limiting rod in place. Similarly, the other limiting rods are adjusted and fixed to fix the base plate on the bed for easy use.

[0016] Preferably, the adjusting and limiting mechanism further includes a second telescopic rod, wherein the second telescopic rod passes through the inner wall of the second spring, and its two ends are respectively fixedly installed on one side of the inner wall of the slide groove and one side of the locking block.

[0017] The effect achieved by the above components is that by setting the second telescopic rod, the inner wall of the second spring can be supported and reinforced, making it less prone to damage.

[0018] Preferably, a pull block is fixedly installed on one side of the card block, and several anti-slip protrusions are fixedly installed on both sides of the pull block.

[0019] The effect achieved by the above components is that by setting up the pull block, the contact area on one side of the block can be increased, making it easier to manually hold and pull it.

[0020] The beneficial effects of this utility model are:

[0021] By setting up a traction mechanism, when performing traction treatment on fracture patients, the injured leg can be fixed to the slide and fixation frame using a fixation component. Then, according to the treatment needs, the self-locking motor is activated to drive the threaded rod to rotate, which in turn causes the threaded block to slide to one end on the inner wall of the base plate. Then, under the pull of the first telescopic rod and the first spring, the slide can move to one end within the inner wall of the base plate. The first spring and the first telescopic rod act as a buffer between the slide and the threaded frame, preventing the threaded block from moving too fast and causing excessive traction. This allows the slide to perform flexible traction according to the actual usage during the traction process, avoiding secondary injuries and improving treatment efficiency.

[0030] Figure 1-4 The illustrated leg fracture traction device includes a base plate 1. A traction mechanism 2 is provided on one side of the base plate 1. The traction mechanism 2 can fix and limit the patient's leg on the slide 25 and the fixation frame 27 through the fixation component 28. Then, the threaded rod 21 moves the threaded hole block 23 to drive the slide 25 to move and provide flexible traction to the patient's leg, thereby avoiding excessive traction and secondary injury.

The inner wall of slide 25 is fitted onto the outer surface of threaded rod 21, and one end is slidably connected to the inner wall of base plate 1. Fixing components 28 are provided on one side of slide 25 and one side of fixing frame 27.

Two first springs 26 are provided, with the inner wall of the first springs 26 fitted onto the outer surface of the first telescopic rods 24, and the two ends respectively fixedly installed on the threaded hole block 23 and one side of slide 25. When performing traction treatment on fracture patients, the injured leg can be fixed to the slide 25 and the fixation frame 27 using the fixation component 28. Then, according to the treatment needs, the self-locking motor 22 is activated to drive the threaded rod 21 to rotate, which in turn drives the screw hole block 23 to slide to one end on the inner wall of the base plate 1. Then, under the pull of the first telescopic rod 24 and the first spring 26, the slide 25 can move to one end in the inner wall of the base plate 1. The first spring 26 and the first telescopic rod 24 will play a buffering traction effect between the slide 25 and the screw hole frame, avoiding the situation where the screw hole block 23 moves too fast and causes excessive traction. This allows the slide 25 to perform flexible traction according to the actual use during the traction process, avoiding secondary injury and improving treatment efficiency.

One end of the protrusion 285 is inserted into the inner wall of the round hole 286. By setting the round holes 286 and the protrusion 285, when the strap 281 is inserted into the inner wall of the square ring block 284 and then folded back, the protrusion 285 will be inserted into the corresponding round hole 286, which will initially fix and limit the strap 281, improving the fixation effect of the strap 281. Anti-slip blocks 29, made of rubber, are fixedly installed on one side of both the slide 25 and the fixing frame 27. By setting the anti-slip blocks 29, the contact friction between the slide 25 and the fixing frame 27 can be increased, making it more secure and stable when fixing the patient's leg.

Second springs 34, the two ends of which are respectively fixedly installed on one side of the locking block 35 and one side of the inner wall of the sliding groove 33. When the base plate 1 needs to be installed and fixed on the hospital bed for use, the locking block 35 can be manually slid to one end in the sliding groove 33 according to the width of the bed, causing the second spring 34 to retract. Then, the limiting rod 31 is pulled outward in the inner wall of the base plate 1 to a certain position, so that one side of the limiting rod 31 abuts against the edge of the hospital bed. At this time, the locking block 35 is released, and under the reset action of the second spring 34, one end can be locked into the corresponding locking hole 32 to fix the adjusted limiting rod 31. Similarly, the other limiting rods 31 are adjusted and fixed to fix the base plate 1 on the bed for easy use.

[0034] Figure 1-4The adjustment limiting mechanism 3 shown also includes a second telescopic rod 36, which passes through the inner wall of the second spring 34, and its two ends are respectively fixedly installed on one side of the inner wall of the slide groove 33 and one side of the locking block 35.

A pull block 37 is fixedly installed on one side of the locking block 35, and several anti-slip protrusions are fixedly installed on both sides of the pull block 37. By setting the pull block 37, the contact area on one side of the locking block 35 can be increased, making it easier to manually grip and pull it.

[0035] Working principle: When performing traction treatment on fracture patients, after placing the patient's leg above the slide 25 and fixation frame 27, one end of the strap 281 can be inserted into the inner wall of the square ring block 284. Then, it is folded back, and the hook-and-loop fastener 282 on one side is attached to the loop fastener 283. This binds and fixes the patient's leg to one side of the slide 25 and fixation frame 27, limiting and fixing it. Then, according to the treatment needs, the self-locking motor 22 is activated to drive the threaded rod 21 to rotate, which can drive the screw hole block 23 to slide to one end on the inner wall of the base plate 1. Then, under the pull of the first telescopic rod 24 and the first spring 26, the slide 25 can move to one end in the inner wall of the base plate 1. The first spring 26 and the first telescopic rod 24 will play a buffering traction effect between the slide 25 and the screw hole frame, avoiding the situation where the screw hole block 23 moves too fast and causes excessive traction. This allows the slide 25 to perform flexible traction according to the actual use during the traction process, avoiding secondary injury and improving treatment efficiency.

[0036] When the base plate 1 needs to be installed and fixed on the hospital bed for use, the locking block 35 can be manually slid to one end in the sliding groove 33 according to the width of the bed, causing the second spring 34 to retract. Then, the limiting rod 31 is pulled outward in the inner wall of the base plate 1 to a certain position, so that one side of the limiting rod 31 abuts against the edge of the hospital bed. At this time, the locking block 35 is released, and under the reset action of the second spring 34, one end can be locked into the corresponding locking hole 32 to fix the adjusted limiting rod 31. Similarly, the other limiting rods 31 are adjusted and fixed to fix the base plate 1 on the bed for easy use.
