Description

Technical Field

[0001] The present invention relates to the field of medical instruments, and more particularly to a lower leg fracture correction device. Background Art

[0002] During the rehabilitation process of patients with leg fractures, they need to wear a brace to help the fractured limb recover. A lower limb brace is an instrument used in orthopedic surgery, which is mainly used to support and fix the bone structure of the lower limb fracture or after surgery.

[0003] In the prior art, for example, Chinese patent "CN215307164U" proposes a walking fixation brace for lower limb fractures, including an outer support plate body, a boot-shaped fracture fixation support inside the support plate body, and slide plates with buffer springs fixedly connected on both sides of the boot-shaped support, which are connected to the support plate body.

[0004] However, in the above-mentioned patent, due to its relatively fixed structure, if the wearer with less severe injuries wears it, his movement will be hindered. In addition, if the patient has a fracture, a certain angle is required between the calf and the thigh to achieve the most comfortable posture for the injured person. Since it cannot be flexibly adjusted, the fracture site of such patients will be subjected to greater pressure when wearing it. Therefore, it cannot be worn by patients with different injuries, which is inconvenient and has certain limitations when used.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a lower leg fracture orthopedic device. Summary of the invention

[0006] The object of the present invention is to provide a lower leg fracture orthopedic device to solve the above-mentioned problems.

[0007] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows: The lockhole that is formed on the upper part of the body is formed on the upper part of the body, and the lockhole that is formed on the lower part of the body is formed on the upper part of the body, and the lockhole that is formed on the lower part of the body is formed on the bottom of the body.

[0008] As a further improvement of the present invention, a screw rod is rotatably connected inside the connecting rod, a limiting rod is fixedly connected below the connecting rod, and the screw rod is located in the middle of the two limiting rods.

[0009] As a further improvement of the present invention, the outer wall of the screw is threadedly connected to a support rod, the support rod and the limit rod are slidably connected, one side of the connecting rod is rotatably connected to a knob, the end of the knob located inside the connecting rod and the top of the screw are fixedly connected to bevel gears, the two bevel gears are located inside the connecting rod, and the two bevel gears are meshed.

[0010] As a further improvement of the present invention, one side of the connecting rod is fixedly connected to a mounting rod, the bottom of the mounting rod is rotatably connected to a base plate, one side of the bottom of the mounting rod is rotatably connected to a sliding rod, the top of the base plate is rotatably connected to a swing rod, and the bottom of the sliding rod is slidably connected to the inside of the swing rod.

[0011] As a further improvement of the present invention, a No. 2 spring is rotatably connected above the base plate, the No. 2 spring is coaxially connected to the swing rod, and one end of the No. 2 spring away from the base plate is rotatably connected to the bottom of the sliding rod.

[0012] As a further improvement of the present invention, a calf sleeve is fixedly connected between the two mounting rods, an airbag is installed on the calf sleeve, a micro air pump is fixedly connected to the outside of the calf sleeve, and the output end of the micro air pump is fixedly connected through the calf sleeve and the input end of the airbag.

[0013] As a further improvement of the present invention, a micro air pump is fixedly connected to the outside of the calf sleeve, and the output end of the micro air pump passes through the calf sleeve and is fixedly connected to the input end of the airbag.

[0014] As a further improvement of the present invention, a thigh sleeve is fixedly connected between the two fixing rods, and the four thigh sleeves are equidistantly distributed.

[0015] As a further improvement of the present invention, an ankle sleeve is fixedly connected between the two mounting rods, and the ankle sleeve is located below the calf sleeve.

[0016] As a further improvement of the present invention, an arc-shaped plate is fixedly connected below the two mounting rods, and a pressure monitor is installed above the arc-shaped plate.

[0017] Compared with the prior art, the advantages of the present invention are: In the present invention, the wearer can rotate the bolt to drive the plug-in rod to slide above the connecting rod, thereby releasing the fixed limit between the fixing rod and the connecting rod. In addition, the wearer can rotate the fixing rod to a certain angle and then rotate the bolt in the opposite direction to make the plug-in rod plugged into the inside of the round hole. Through this design, when treating patients with different injury conditions, if the wearer's injury is relatively light and the leg can move with a large range of motion, the wearer can release the limit between the fixing rod and the connecting rod, so that the device can play a certain protective role when the injured leg of the wearer with relatively light injuries moves. If the wearer's injury is relatively serious and the leg cannot be bent and moved, the wearer can achieve a more stable protection for the injured leg of the patient with relatively heavy injuries after rotating the fixing rod and the connecting rod to a comfortable wearing angle and using the plug-in rod to limit the position, thereby preventing leg pain caused by inadvertent leg movement of the patient with relatively heavy injuries.

[0018] In the present invention, if the user is tall, the distance between the fixed rod and the support rod needs to be increased. At this time, the user can hold the two knobs with both hands at the same time and turn the knobs. After the knobs are turned, the engagement between the bevel gears will drive the screw to rotate. When the screw rotates, since the support rod and the limit rod fixedly connected to the bottom of the connecting rod are slidably connected, the support rod will be driven to slide on the outer wall of the limit rod when the screw rotates. When the support rod slides on the outer wall of the limit rod, the distance between the support rod and the fixed rod can be increased, thereby making it easier for taller users to wear.

[0019] In the present invention, when the user starts the micro air pump, the output end of the micro air pump will inflate the airbag, and the airbag will expand after being inflated by the micro air pump. After the expansion, the airbag can wrap the user's calf, thereby increasing the weight of the user's calf when wearing it. In addition, the pressure monitor above the arc plate will record the pressure on the arc plate when the user walks while wearing it and monitor and record it, so as to accurately grasp the wearer's recovery period.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention. Example 1

[0023] See also Figure 1-6 A leg fracture correction device comprises: a fixing rod 1, a connecting rod 13 is rotatably connected to the bottom of the fixing rod 1, a round hole 12 is opened at the bottom of the fixing rod 1, and eight round holes 12 are evenly distributed at the bottom of the fixing rod 1, a plug-in rod 15 is slidably connected to the side of the connecting rod 13 away from the bottom of the fixing rod 1, a stopper 16 is fixedly connected to the outer wall of the plug-in rod 15, one side of the stopper 16 is in contact with one side of the inside of the connecting rod 13, and a No. 1 spring 17 is sleeved on the outer wall of the plug-in rod 15, and the No. 1 spring The spring 17 is located between the stopper 16 and the connecting rod 13, and a bolt 14 is rotatably connected to the top of the connecting rod 13. The outer wall of the bolt 14 is threadedly connected to a mounting plate 18, and one side of the mounting plate 18 is fixedly connected to one end of the plug-in rod 15. The No. 1 spring 17 is located between the stopper 16 and the mounting plate 18, and one end of the bolt 14 is fixedly connected to a handle 19. Eight plug-in rods 15 are equidistantly distributed on one side of the mounting plate 18, and one end of the eight plug-in rods 15 are all clamped in the eight circular holes 12.

[0024] In this embodiment, if the user needs to release the fixed limit between the fixing rod 1 and the connecting rod 13, the user can turn the handle 19 to drive the bolt 14 to rotate. Since the outer wall of the bolt 14 is threadedly connected to the mounting plate 18, when the bolt 14 is rotated, the mounting plate 18 will gradually move away from the top of the connecting rod 13. In the process of the mounting plate 18 gradually moving away from the top of the connecting rod 13, the plug-in rod 15 will slide inside the connecting rod 13. During this process, the No. 1 spring 17 sleeved on the outer wall of the plug-in rod 15 will be elastically deformed and contracted after being squeezed by the stopper 16 and store a certain amount of elastic potential energy. As the bolt 14 continues to rotate, when one end of the plug-in rod 15 is completely disengaged from the inside of the circular hole 12, the plug-in rod 15 will be completely disengaged from the inside of the circular hole 12. After separation, the fixed limit between the fixing rod 1 and the connecting rod 13 can be released. At this time, the fixing rod 1 and the connecting rod 13 can rotate freely. In addition, if the user's legs are inconvenient to move, it is necessary to rotate the fixing rod 1 and the connecting rod 13 to a certain angle and fix the limit. After one end of the plug-in rod 15 is disengaged from the inside of the circular hole 12, the fixing rod 1 and the connecting rod 13 are rotated to the required angle, and then the bolt 14 is rotated in the opposite direction to make the plug-in rod 15 gradually slide in the direction of the circular hole 12, and finally be clamped in the inside of the circular hole 12. The No. 1 spring 17 can apply a certain extrusion force between the mounting plate 18 and the top of the connecting rod 13 to enhance the tightness of the bolt 14. Example 2

[0025] See also Figure 1-6 The connecting rod 13 is rotatably connected to the screw rod 2 inside, and the lower part of the connecting rod 13 is fixedly connected to the limit rod 21, and the screw rod 2 is located in the middle of the two limit rods 21. The outer wall of the screw rod 2 is threadedly connected to the support rod 24, and the support rod 24 and the limit rod 21 are slidably connected. One side of the connecting rod 13 is rotatably connected to the knob 23, and the end of the knob 23 located inside the connecting rod 13 and the top of the screw rod 2 are fixedly connected to the bevel gear 22. The two bevel gears 22 are both located inside the connecting rod 13. The two bevel gears 22 are engaged, one side of the connecting rod 13 is fixedly connected with the mounting rod 25, the bottom of the mounting rod 25 is rotatably connected with the base plate 3, one side below the mounting rod 25 is rotatably connected with the sliding rod 31, the top of the base plate 3 is rotatably connected with the swing rod 32, the bottom of the sliding rod 31 is slidably connected inside the swing rod 32, the top of the base plate 3 is rotatably connected with a No. 2 spring 33, the No. 2 spring 33 and the swing rod 32 are coaxially connected, and the end of the No. 2 spring 33 away from the base plate 3 is rotatably connected to the bottom of the sliding rod 31.

[0026] In this embodiment, if the user is tall, the distance between the fixed rod 1 and the support rod 24 needs to be increased. At this time, the user can hold the two knobs 23 with both hands at the same time and turn the knobs 23. After the knobs 23 are turned, the meshing between the bevel gears 22 will drive the screw rod 2 to rotate. When the screw rod 2 rotates, the support rod 24 is slidably connected to the limit rod 21 fixedly connected to the lower part of the connecting rod 13. Therefore, when the screw rod 2 rotates, the support rod 24 is driven to slide on the outer wall of the limit rod 21. When the support rod 24 slides on the outer wall of the limit rod 21, the distance between the support rod 24 and the fixed rod 1 is increased. The distance between the two springs 31 and 32 can be increased, so that it is convenient for users with taller height to wear the shoes. When the user wears the shoes and walks, the ankles will move. When the wearer's ankles move, the base plate 3 will be driven to rotate. When the base plate 3 rotates, the lower part of the sliding rod 31 will slide inside the swing rod 32. During this process, the No. 2 spring 33 will be elastically deformed after being squeezed and store a certain amount of elastic potential energy. In the process of the base plate 3 gradually returning to its original position, the No. 2 spring 33 in a compressed state will also gradually return to its original position. The No. 2 spring 33 has a certain blocking effect on the rotation of the base plate 3, so as to exercise the activity of the user's ankle. Example 3

[0027] See also Figure 1-6 A calf sleeve 26 is fixedly connected between the two mounting rods 25, and an air bag 27 is installed on the calf sleeve 26. A micro air pump 28 is fixedly connected to the outside of the calf sleeve 26, and the output end of the micro air pump 28 passes through the calf sleeve 26 and the input end of the air bag 27 and is fixedly connected. The micro air pump 28 is fixedly connected to the outside of the calf sleeve 26, and the output end of the micro air pump 28 passes through the calf sleeve 26 and the input end of the air bag 27 and is fixedly connected. A thigh sleeve 11 is fixedly connected between the two fixing rods 1, and the four thigh sleeves 11 are equidistantly distributed. An ankle sleeve 29 is fixedly connected between the two mounting rods 25, and the ankle sleeve 29 is located below the calf sleeve 26. An arc plate 34 is fixedly connected below the two mounting rods 25, and a pressure monitor 35 is installed above the arc plate 34.

[0028] In this embodiment, when the user starts the micro air pump 28, the output end of the micro air pump 28 will inflate the airbag 27. The airbag 27 will expand after being inflated by the micro air pump 28. After the expansion, the airbag 27 can wrap the user's calf, thereby increasing the weight of the user's calf when wearing it. In addition, the pressure monitor 35 above the arc plate 34 will record the pressure exerted on the arc plate 34 when the user walks while wearing it and monitor and record it. If the pressure exerted on the bottom end of the arc plate 34 gradually increases, it proves that the user's recovery is good.

[0029] Working principle: Before wearing, the user can adjust the distance between the fixed rod 1 and the support rod 24 according to his / her height. If the user is taller, the distance between the fixed rod 1 and the support rod 24 needs to be increased. At this time, the user can hold the two knobs 23 with both hands at the same time and turn the knobs 23. After the knobs 23 are turned, the meshing between the bevel gears 22 will drive the screw rod 2 to rotate. When the screw rod 2 rotates, since the support rod 24 is slidably connected with the limit rod 21 fixedly connected to the lower part of the connecting rod 13, the rotation of the screw rod 2 will drive the support rod 24 to slide on the outer wall of the limit rod 21. When the support rod 24 slides on the outer wall of the limit rod 21, the distance between the support rod 24 and the fixed rod 1 can be increased, so that it is easier for users with taller height to wear. After the distance between the fixed rod 1 and the support rod 24 is adjusted, If the user's leg injury is minor, it is only necessary to protect the outside of the leg. The user needs to release the fixed limit between the fixing rod 1 and the connecting rod 13, and the user can turn the handle 19 to drive the bolt 14 to rotate. Because the outer wall of the bolt 14 is threadedly connected to the mounting plate 18, when the bolt 14 rotates, the mounting plate 18 will gradually move away from the top of the connecting rod 13. In the process that the mounting plate 18 gradually moves away from the top of the connecting rod 13, the plug-in rod 15 will slide inside the connecting rod 13. In this process, the No. 1 spring 17 sleeved on the outer wall of the plug-in rod 15 will be squeezed by the stopper 16, and will undergo elastic deformation and contraction and store a certain amount of elastic potential energy. As the bolt 14 continues to rotate, when one side of the plug-in rod 15 After the end is completely disengaged from the inside of the circular hole 12, the fixed limit between the fixing rod 1 and the connecting rod 13 can be released, and the fixing rod 1 and the connecting rod 13 can rotate freely. In addition, if the user's legs are inconvenient to move, it is necessary to rotate the fixing rod 1 and the connecting rod 13 to a certain angle and fix the limit. After one end of the plug-in rod 15 is disengaged from the inside of the circular hole 12, the fixing rod 1 and the connecting rod 13 are rotated to the required angle, and then the bolt 14 is rotated in the opposite direction to make the plug-in rod 15 gradually slide in the direction of the circular hole 12, and finally be clamped in the inside of the circular hole 12. At this time, the angle limit between the fixing rod 1 and the connecting rod 13 is completed, and then the user only needs to wear it. In addition, when the user starts the micro air pump 28, the output end of the micro air pump 28 will inflate the airbag 27. The airbag 27 will expand after being inflated by the micro air pump 28. After the airbag 27 expands, it can wrap the user's calf, thereby increasing the weight of the user's calf when wearing it. In addition, the pressure monitor 35 above the arc plate 34 will record the pressure exerted on the arc plate 34 when the user walks while wearing it and monitor and record it. If the pressure exerted on the bottom end of the arc plate 34 gradually increases, it proves that the user's recovery is good.
