Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an orthopedic traction frame which is convenient to move. Background Art

[0002] An orthopedic traction frame is a commonly used medical device in orthopedics, usually used to assist in the implementation of traction to improve the traction effect. When implementing traction, in order to cooperate with medical staff, the orthopedic traction frame needs to be moved to a suitable position, so an orthopedic traction frame that is easy to move is needed.

[0003] The existing orthopedic traction frames that are easy to move usually use running wheels to move. When they are moved to the specified position, the running wheels need to be fixed. At this time, the medical staff should step on the wheel brakes of all the running wheels in time to achieve complete fixation of the entire orthopedic traction frame. Generally, in order to ensure the smooth implementation of the traction operation, the general orthopedic traction frame is relatively large, and the medical staff needs to step on all the running wheel brakes to go around the orthopedic traction frame. The process of closing the wheel brakes is relatively cumbersome, which prolongs the preparation time for the traction operation to a certain extent. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an orthopedic traction frame that is easy to move, so as to solve the technical problem that the existing orthopedic traction frame that is easy to move is cumbersome to operate when closing the wheel brake, which prolongs the preparation time for the traction operation to a certain extent.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a conveniently movable orthopedic traction frame, comprising a traction frame body, a base and walking wheels, a limiting mechanism is arranged on the top of the walking wheels, the limiting mechanism comprises a second cavity and a limiting hole, an electromagnet is arranged inside the second cavity, a magnetic seat is arranged at the bottom of the electromagnet, a spring is arranged at the bottom of the magnetic seat, a limiting rod is arranged at the bottom of the spring, and a handhold mechanism is arranged on one side of the top of the base.

[0006] By adopting the above technical solution, when the walking wheel is needed to drive the entire traction frame body to move, the electromagnet is controlled to be energized. At this time, under the action of the electromagnetic field, the magnetic attraction attracts the limit rod to move upward, squeezing the spring, so that the limit rod smoothly leaves the limit hole, and the restriction of the limit rod on the walking wheel is released, making it easier for it to move. When it moves to the specified position, the electromagnet is controlled to be de-energized, and under the action of the elastic restoring force of the spring, the limit rod is pushed into the limit hole.

[0007] Furthermore, a first cavity is provided on the base, the travel wheel is rotatably connected to the first cavity via a connecting shaft, and the limiting hole passes through the travel wheel and the connecting shaft.

[0008] By adopting the above technical solution, the walking wheel is rotatably connected to the first cavity through the connecting shaft, so that the movement process of the traction frame body can be carried out smoothly, and the traction frame body is convenient to move to the specified position.

[0009] Furthermore, the springs are provided in two groups, and the two groups of springs are symmetrically arranged, and the magnetic conductive seat and the limiting rod are both fixedly connected to the springs.

[0010] By adopting the above technical solution, two groups of springs are provided in the second cavity at the top of each walking wheel, and two groups of symmetrical springs are used to lock both sides of the same walking wheel at the same time, ensuring that the walking wheel remains stable when locked.

[0011] Furthermore, the limiting rod is made of ferritic stainless steel, and the limiting rod is matched with the limiting hole.

[0012] By adopting the above technical solution, the ferrite stainless steel material can ensure that the limit rod can respond to the magnetic field force of the electromagnet and can also ensure that the limit rod will not be corroded due to humid air.

[0013] Furthermore, the hand-holding mechanism includes a fixed shaft, a handle is provided at one end of the fixed shaft, an armrest is provided at the end of the handle away from the fixed shaft, a first plug hole is provided on the fixed shaft, a first through hole and a second plug hole are provided on the handle, and a second through hole is provided on the armrest.

[0014] By adopting the above technical solution, when pushing the traction frame body to move, the handle and the armrest can be extended so that the hand-holding mechanism is moved out of the bottom of the traction frame body, which facilitates the movement of the traction frame body.

[0015] Furthermore, the fixed shaft is slidably connected to the handle, and the handle is slidably connected to the armrest.

[0016] By adopting the above technical solution, the fixed shaft and the handle, as well as the handle and the armrest are all connected by sliding, so that medical staff can pull out the armrest or push back the handle, and pull out or push the handle back to the fixed shaft as needed.

[0017] Furthermore, the first pin hole is matched with the first through hole, and the second pin hole is matched with the second through hole.

[0018] By adopting the above technical solution, the first pin hole and the first through hole and the second pin hole and the second through hole have a high degree of adaptability, so that after the hand-held mechanism is adjusted to a suitable length according to the height and arm length of the user, the pin can be smoothly inserted into the first pin hole and the first through hole and the second pin hole and the second through hole.

[0019] Furthermore, a hydraulic cylinder is provided at the bottom of the traction frame body, and the hydraulic cylinder is fixedly connected to the traction frame body.

[0020] By adopting the above technical solution and setting the hydraulic cylinder, it is convenient to effectively adjust the height of the traction frame body, because patients using orthopedic traction frames usually have difficulty in movement. If the height of the traction frame body is too high, it is not conducive for the patient to lie on the traction frame body.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] 1. The utility model provides an electromagnet, a spring, a limit rod and a limit hole. When the walking wheel is needed to drive the entire traction frame body to move, the electromagnet is controlled to be energized. At this time, under the action of the electromagnetic field, the magnetic attraction attracts the limit rod to move up and squeezes the spring, so that the limit rod smoothly leaves the limit hole, and the restriction of the limit rod on the walking wheel is released, which is convenient for walking. When it moves to the specified position, the electromagnet is controlled to be de-energized. Under the action of the elastic restoring force of the spring, the limit rod is pushed into the limit hole, so that the four walking wheels are limited at the same time, thereby completing the fixation of the entire traction frame body. The fixing and starting process is simple, and there is no need to turn off or enable the walking wheels in sequence, which saves time to a certain extent.

[0023] 2. The utility model provides a fixed shaft, a handle and an armrest. When the traction frame body is pushed to move, the handle and the armrest can be extended so that the hand-holding mechanism is moved out of the bottom of the traction frame body, which is convenient for pushing the traction frame body to move. When the traction technique is implemented, the handle and the armrest can be retracted, and the hand-holding mechanism can be retracted to the bottom of the traction frame body to avoid the hand-holding mechanism protruding and affecting the normal implementation of the traction technique.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1:

[0032] A conveniently movable orthopedic traction frame, such as Figure 1-Figure 4 As shown, it includes a traction frame body 1, a base 2 and a walking wheel 5. A limiting mechanism 6 is arranged on the top of the walking wheel 5. The limiting mechanism 6 includes a second cavity 61 and a limiting hole 66. An electromagnet 62 is arranged inside the second cavity 61. A magnetic seat 63 is arranged at the bottom of the electromagnet 62. A spring 64 is arranged at the bottom of the magnetic seat 63. A limiting rod 65 is arranged at the bottom of the spring 64. A hand-holding mechanism 7 is arranged on one side of the top of the base 2. When the walking wheel 5 is required to drive the entire traction frame body 1 to move, the electromagnet 62 is controlled to be energized. At this time, in the electromagnetic field Under the action, the magnetic attraction attracts the limit rod 65 to move upward, squeezing the spring 64, so that the limit rod 65 smoothly leaves the limit hole 66, releasing the restriction of the limit rod 65 on the walking wheel 5, making it convenient for it to walk. When it moves to the specified position, the electromagnet 62 is controlled to be powered off. Under the action of the elastic restoring force of the spring 64, the limit rod 65 is pushed into the limit hole 66, so that the four walking wheels 5 are limited at the same time, thereby completing the fixation of the entire traction frame body 1. The fixing and starting process is simple, and there is no need to turn off or enable the walking wheels 5 one by one, which saves time to a certain extent.

[0033] See also Figure 3 , Figure 4 A first cavity 4 is provided on the base 2, and the walking wheel 5 is rotatably connected to the first cavity 4 through a connecting shaft, and a limiting hole 66 passes through the walking wheel 5 and the connecting shaft, and the walking wheel 5 is rotatably connected to the first cavity 4 through the connecting shaft, so that the movement process of the traction frame body 1 can be carried out smoothly, and it is convenient for the traction frame body 1 to move to a specified position. The limiting hole 66 passes through the walking wheel 5 and the connecting shaft, so that after the limiting rod 65 moves down smoothly under the action of the spring 64, the limiting rod 65 moves to the limiting hole 66, locks the walking wheel 5 and the connecting shaft, and then fixes the traction frame body 1 at the specified position.

[0034] See also Figure 3 , Figure 4Two groups of springs 64 are provided, and the two groups of springs 64 are symmetrically arranged. The magnetic seat 63 and the limit rod 65 are fixedly connected to the spring 64. In the second cavity 61 at the top of each walking wheel 5, two groups of springs 64 are provided. Two groups of symmetrical springs 64 are used to lock both sides of the same walking wheel 5 at the same time to ensure that the walking wheel 5 remains stable when locked. The magnetic seat 63 and the limit rod 65 are fixedly connected to the spring 64, so that the limit rod 65 is kept from falling when it moves into or out of the limit hole 66 under the coordinated action of the magnetic attraction force of the electromagnet 62 and the elastic restoring force of the spring 64.

[0035] See also Figure 3 , Figure 4 The limit rod 65 is made of ferritic stainless steel, and the limit rod 65 is adapted to the limit hole 66. The ferritic stainless steel material can ensure that the limit rod 65 can respond to the magnetic field force of the electromagnet 62, and can also ensure that the limit rod 65 will not be corroded due to humid air. The high adaptability of the limit rod 65 and the limit hole 66 can ensure that the limit rod 65 can be smoothly extended into or moved out of the limit hole 66 to lock the walking wheel 5 or release the restriction on the walking wheel 5.

[0036] Embodiment 2:

[0037] See also Figure 1 , Figure 2 , Figure 3 The hand-holding mechanism 7 includes a fixed shaft 71, a handle 72 is provided at one end of the fixed shaft 71, and an armrest 73 is provided at the end of the handle 72 away from the fixed shaft 71. A first plug hole 74 is provided on the fixed shaft 71, a first through hole 75 and a second plug hole 76 are provided on the handle 72, and a second through hole 77 is provided on the armrest 73. When pushing the traction frame body 1 to move, the handle 72 and the armrest 73 can be extended so that the hand-holding mechanism 7 is moved out of the bottom of the traction frame body 1, which is convenient for pushing the traction frame body 1 to move. When the traction technique is implemented, the handle 72 and the armrest 73 can be retracted, and the hand-holding mechanism 7 can be retracted to the bottom of the traction frame body 1 to avoid the hand-holding mechanism 7 protruding and affecting the normal implementation process of the traction technique.

[0038] See also Figure 1 , Figure 2 , Figure 3 The fixed shaft 71 is slidably connected to the handle 72, and the handle 72 is slidably connected to the armrest 73. The fixed shaft 71 and the handle 72, as well as the handle 72 and the armrest 73, are all slidably connected, so that the medical staff can pull out the armrest 73 or push it back to the handle 72, and pull out or push the handle 72 back to the fixed shaft 71 as needed, so that the hand-holding mechanism 7 can be smoothly extended out of the traction frame body 1 or retracted to the bottom of the traction frame body 1.

[0039] See also Figure 1 , Figure 2 , Figure 3 The first pin hole 74 is adapted to the first through hole 75, and the second pin hole 76 is adapted to the second through hole 77. The high adaptability of the first pin hole 74 and the first through hole 75, the second pin hole 76 and the second through hole 77 allows the pin to be smoothly inserted into the first pin hole 74 and the first through hole 75 as well as the second pin hole 76 and the second through hole 77 after the handhold mechanism 7 is adjusted to an appropriate length according to the height and arm length of the user, thereby fixing the handhold mechanism 7 to prevent it from changing size during movement and affecting the smooth progress of the movement process.

[0040] See also Figure 1 , Figure 2 , Figure 3 A hydraulic cylinder 3 is provided at the bottom of the traction frame body 1, and the hydraulic cylinder 3 is fixedly connected to the traction frame body 1. The setting of the hydraulic cylinder 3 is convenient for effectively adjusting the height of the traction frame body 1. Patients using orthopedic traction frames usually have difficulty in moving. If the height of the traction frame body 1 is high, it is not conducive to the patient lying on the traction frame body 1. At the same time, there are differences in the heights of medical staff. When performing traction surgery, if the traction frame body 1 of the same height is used, the medical staff will perform the surgery in an inappropriate posture, which is easy to cause fatigue.

[0041] The implementation principle of the utility model is as follows: first, the electromagnet 62 is controlled to be energized, and the magnetic attraction force of the electromagnetic field is transmitted to the limit rod 65 made of ferrite stainless steel through the magnetic base 63, so that the limit rod 65 moves upward under the action of the magnetic attraction force, leaves the limit hole 66 and gradually approaches the magnetic base 63, and the restriction of the walking wheel 5 is released. In this process, the limit rod 65 smoothly squeezes the spring 64, so that the spring 64 contracts smoothly, and the spring 64 accumulates force during the contraction process; secondly, the handle 72 is pulled out from the fixed shaft 71, and the handrail 73 is pulled out from the handle 72. After adjusting the hand-holding mechanism 7 to a position extending out of the bottom of the traction frame body 1, the pin is passed through the first pin hole 74 and the first through hole 75, as well as the second pin hole 76 and the second through hole 77 in sequence, and the hand The armrest 7 is fixed; then, the handrail 73 is held, and the traction frame body 1 on the base 2 is driven to move to a suitable position under the action of the walking wheel 5; then, the electromagnet 62 is controlled to be powered off, the magnetic attraction of the electromagnetic field disappears, and the stored spring 64 pushes the limit rod 65 downward under the action of the elastic restoring force. At the same time, the medical staff pushes and pulls the traction frame body 1 back and forth near the designated position until the limit rod 65 moves to the top of the limit hole 66 and enters smoothly, locks the walking wheel 5 and the connecting shaft, and completes the fixation of the traction frame body 1; finally, the hydraulic cylinder 3 is adjusted to make the traction frame body 1 move downward, so that the patient can move to the traction frame body 1 conveniently, and then the hydraulic cylinder 3 is adjusted again to adjust the traction frame body 1 to a height that is convenient for medical staff to perform traction.
