Description

Technical Field

[0001] The present application relates to the technical field of medical machinery, and in particular to a traction reducer for ankle fracture surgery. Background Art

[0002] When an ankle fracture occurs, targeted surgery and rehabilitation are required at the site. A traction reducer can be installed there to fix the fracture. When the patient is walking, the force on the foot is directly transmitted to the calf through the traction reducer across the ankle joint, ensuring that the patient can move appropriately without causing too serious impact on the patient's life. Traditional enterprise servers are composed of a bracket, a tightening plate and a load-bearing plate. During use, the sole of the patient's foot is in contact with the load-bearing plate, and the tightening belt is tied to the patient's calf, thereby achieving a traction and reduction effect. However, in actual use, the tightening belt is in contact with the calf for a long time and tightened, resulting in poor blood circulation in the calf. In this regard, the present application document proposes a traction reducer during ankle fracture surgery, which aims to solve the above-mentioned problems. Summary of the invention

[0003] The present application proposes a traction and reduction device for ankle fracture surgery, which has the advantage of alleviating the poor blood circulation in the patient's calf caused by the tightness of the band, and is used to solve the problem of discomfort caused by the patient's calf being tightened for a long time.

[0004] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a traction and reduction device for ankle fracture surgery, comprising a fixed bracket, a connecting rail is fixedly installed on the front side of the fixed bracket near both sides, and holes for matching screws are opened on both sides of the connecting rail, and are distributed in a linear array.

[0009] Specifically, a tightening belt is fixedly installed on the front side of the mounting seat, and a front end of the tightening belt is provided, which is sleeved on the patient's calf and fixed to the patient's calf after being tightened.

[0010] Furthermore, the buffer device includes a bearing plate, the top of which is used to bear the patient's feet, and the bearing plate has different specifications and can be adjusted according to the size of the patient's feet.

[0011] Specifically, connecting shaft seats are fixedly installed on both sides of the top of the supporting plate near the tail end, and the top of the connecting shaft seat is sleeved with the connecting shaft sleeve. A circular groove is opened at the center of the bottom of the supporting plate, and a water storage rubber bin is fixedly installed inside the circular groove. A pipe groove is opened at the bottom of the supporting plate, and the pipe groove extends from the end of the supporting plate to the inside of the circular groove.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] A traction reducer for ankle fracture surgery, see Figure 1-Figure 3 , including a fixed bracket 1, a connecting rail 2 is fixedly installed on the front side of the fixed bracket 1 near both sides, and holes for matching screws are opened on both sides of the connecting rail 2 and are distributed in a linear array.

[0025] See also Figure 1-Figure 3 A slide groove 3 is provided on the front of the fixed bracket 1 between the connecting rails 2, and a limiting slide bar 4 is fixedly installed on the top of the inner wall of the slide groove 3 near the front side. The limiting slide bar 4 limits the displacement of the massage device 12.

[0026] See also Figure 1-Figure 3 A sleeve 5 is fixedly installed on the top of the inner wall of the slide groove 3 near the rear side, a connecting nozzle 6 is provided on the top of the fixed bracket 1, the connecting nozzle 6 is connected to the sleeve 5, a liquid guide tube 7 is fixedly sleeved on the top of the connecting nozzle 6, and a tightening device 8 is fixedly installed near the top and bottom ends of the connecting rail 2, and the tightening device 8 is fixedly sleeved on the patient's calf part.

[0027] See also Figure 1-Figure 3 A connecting base 9 is fixedly installed at the bottom of the fixed bracket 1, and a connecting sleeve 10 is fixedly installed at the front end of the connecting base 9 near the two sides. A buffer device 11 is provided on the outer movable sleeve of the connecting sleeve 10, and the buffer device 11 is connected to the catheter 7. A massage device 12 is movably installed on the outer side of the limiting slide rod 4.

[0028] Compared with the fixed brackets in the comparative document which are respectively arranged on both sides of the patient's calf, which causes the patient to easily rub and squeeze the calf during use and cause discomfort, the device involved in the present application document adopts a fixed bracket 1 to fix the tightening device 8, and the width of the connecting base 9 and the tightening device 8 is such that there is a large distance between the fixed bracket 1 and the patient's calf, so that the fixed bracket 1 cannot come into contact with the patient's calf, thereby avoiding the discomfort caused by the patient during use and improving the practicality of the device.

[0029] Since the top of the connecting base 9 is connected to the bottom of the fixing bracket 1 by bolts, the device can replace part of the buffer device 11 according to the size of the patient's foot, thereby adjusting the size of the supporting plate 111, thereby improving the practicality of the device.

[0030] See also Figure 1-Figure 4 The tightening device 8 includes a mounting seat 81, and a fixing buckle 82 is fixedly installed on the back side of the mounting seat 81 near both ends. The fixing buckle 82 is connected to the connecting rail 2 by bolts. After connection, the bolts match the holes opened in the connecting rail 2.

[0031] See also Figure 4 A tightening belt 83 is fixedly installed on the front of the mounting seat 81, and a strap 84 is arranged at the front end of the tightening belt 83. The strap 84 is sleeved on the patient's calf and fixed to the patient's calf after the strap 84 is tightened.

[0032] See also Figure 5 The buffer device 11 includes a supporting plate 111 , the top of the supporting plate 111 is used to support the patient's feet, and the supporting plate 111 has different specifications and can be adjusted according to the size of the patient's feet.

[0033] See also Figure 2 and Figure 5-Figure 7 A connecting shaft seat 112 is fixedly installed on both sides of the top of the supporting plate 111 near the tail end, and the top of the connecting shaft seat 112 is sleeved with the connecting shaft sleeve 10. A circular groove 113 is opened at the center of the bottom of the supporting plate 111, and a water storage rubber bin 114 is fixedly installed inside the circular groove 113. A pipe groove 115 is opened at the bottom of the supporting plate 111, and the pipe groove 115 extends from the end of the supporting plate 111 to the inside of the circular groove 113. The liquid guide tube 7 is arranged inside the pipe groove 115 and connected to the inner cavity of the water storage rubber bin 114. A liquid pressure device 13 is movably installed at the bottom of the supporting plate 111.

[0034] See also Figure 5-Figure 7The liquid pressing device 13 includes a liquid pressing plate 131, the top of which is fixedly connected to the bottom of the water storage rubber bin 114, a buffer rod 132 is fixedly installed at the top of the liquid pressing plate 131 near the outside, the buffer rod 132 penetrates and cooperates with the supporting plate 111 located above, a buffer spring 133 is clamped on the top of the buffer rod 132, and the bottom of the buffer spring 133 is connected to the supporting plate 111. After the buffer spring 133 releases its elastic potential energy, it will drive the liquid pressing plate 131 to reset, thereby restoring the water storage rubber bin 114 to its original shape.

[0035] A hydraulic device 13 is provided at the bottom of the supporting plate 111, and the supporting plate 111 and the buffer rod 132 are connected by a buffer spring 133. This ensures that when the patient walks a short distance, the supporting plate 111 will not have a hard contact with the ground, but will be buffered by the buffer spring 133, thereby reducing the large vibration amplitude and contact force generated by the contact between the supporting plate 111 and the ground when the patient walks, alleviating the discomfort of the patient during walking and further improving the practicability of the device.

[0036] The rubber water storage chamber 114 filled with liquid is located between the supporting plate 111 and the liquid pressure plate 131. When the patient walks, the rubber water storage chamber 114 will also be compressed. Since the liquid is difficult to be compressed, the rubber water storage chamber 114 will also produce a large resistance to the movement of the liquid pressure plate 131, thereby also playing a buffering and shock-absorbing effect, supplementing the elastic buffering and shock-absorbing of the buffer spring 133, and improving the protective effect of the device on the patient's ankle joint.

[0037] See also Figure 2 and Figure 5-Figure 7 The water storage rubber chamber 114 is initially filled with liquid. When the water storage rubber chamber 114 is squeezed and its volume shrinks, the liquid enters the interior of the sleeve 5 through the liquid guide tube 7.

[0038] See also Figure 2 and Figure 5-Figure 8 The massage device 12 includes a slide 121, and a telescopic rod 122 is fixedly installed at a position near the end of the top of the slide 121. The telescopic rod 122 is movably installed inside the sleeve 5. When the water storage rubber chamber 114 is compressed, the liquid inside enters the sleeve 5 through the liquid guide tube 7 under the action of squeezing, which pushes the telescopic rod 122 to move downward.

[0039] See also Figure 2 and Figure 8 A matching hole 123 is provided at the top of the slide seat 121 near the front end. The matching hole 123 matches and limits the limiting slide bar 4. Under this effect, the slide seat 121 can only move along the axial direction of the limiting slide bar 4.

[0040] See also Figure 8A connecting block 124 is fixedly installed at the front end of the slide 121, and connecting rods 125 are fixedly installed on both sides of the connecting block 124 near the front end. Spring telescopic rods 126 are movably installed on the top and bottom of the connecting rod 125. An arc-shaped massage roller 127 is fixedly installed at the front end of the spring telescopic rod 126. Under the elastic force of the spring telescopic rod 126, the arc-shaped massage roller 127 extends forward and contacts with the patient's calf, and when the slide 121 moves, the arc-shaped massage roller 127 will also move in accordance with the patient's calf.

[0041] See also Figure 4 and Figure 8 , the arc-shaped massage roller 127 is located above 84.

[0042] When the patient is walking, the distance between the supporting plate 111 and the liquid pressing plate 131 will decrease, thereby forming a squeezing effect on the water storage rubber chamber 114. Since the interior of the water storage rubber chamber 114 is initially injected with liquid, when the water storage rubber chamber 114 is squeezed and its volume shrinks, the liquid enters the interior of the sleeve 5 through the liquid guide tube 7. After the liquid enters the interior of the sleeve 5, it will push the telescopic rod 122 to move in the vertical downward direction. At this time, the arc-shaped massage roller 127 extends forward and contacts the patient's calf under the elastic force of the spring telescopic rod 126, and when the slide 121 moves, the arc-shaped massage roller 127 will also move in accordance with the patient's calf, so that the arc-shaped massage roller 127 can massage the contact position between the patient's calf and 84, thereby avoiding the discomfort caused by poor blood flow caused by 84 being in a tight state with the patient's calf for a long time, thereby providing practicality of the device.

[0043] The method of use of the present invention is as follows: During use, a suitable supporting plate 111 is selected according to the size of the patient's foot, and the connecting base 9 is fixed to the fixing bracket 1 with bolts. After that, the patient places the sole of the foot on the top of the supporting plate 111, and then wraps 84 around the outside of the calf and tightens it to complete the fixation. When the patient walks short distances, the supporting plate 111 will not have a hard contact with the ground, but will be buffered by the buffer spring 133, which reduces the large vibration amplitude and contact force generated by the contact between the supporting plate 111 and the ground when the patient walks, thereby alleviating the patient's discomfort during walking. When the patient walks, the distance between the supporting plate 111 and the liquid pressing plate 131 will decrease, thereby forming a squeezing effect on the water storage rubber bin 114. Since the interior of the water storage rubber bin 114 is injected with liquid in the initial state, the water storage rubber bin 114 shrinks in volume when it is squeezed. When the liquid enters the sleeve 5 through the catheter 7, the liquid will push the telescopic rod 122 to move in the vertical downward direction. At this time, the arc-shaped massage roller 127 extends forward and contacts the patient's calf under the elastic force of the spring telescopic rod 126, and when the slide 121 moves, the arc-shaped massage roller 127 will also move in accordance with the patient's calf part, so that the arc-shaped massage roller 127 can massage the contact position between the patient's calf and 84. The liquid-injected water storage rubber bin 114 is located between the bearing plate 111 and the liquid pressure plate 131. When the patient walks, the water storage rubber bin 114 will also be compressed. Since the liquid is difficult to be compressed, the water storage rubber bin 114 will also produce a large resistance to the movement of the liquid pressure plate 131, thereby also playing a buffering and shock-absorbing effect, and supplementing the elastic buffering and shock-absorbing of the buffer spring 133.

[0044] After the patient lifts his foot, the buffer spring 133 releases its stored elastic force and drives the liquid pressure plate 131 to reset, while driving the water storage rubber chamber 114 to restore its original shape, so that the liquid flows into the interior of the water storage rubber chamber 114 through the liquid guide tube 7 and the sleeve 5, and drives the massage device 12 to reset.
