Description

Technical Field

[0001] This invention belongs to the field of orthopedic reduction and fixation technology, specifically an orthopedic reduction and fixation orthopedic correction device for clinical use. Background Technology

[0002] Orthopedic devices refer to a general term for external devices fitted to the limbs, trunk, and other parts of the human body. Their purpose is to prevent or correct deformities of the limbs and trunk, or to treat bone, joint, and neuromuscular diseases and compensate for their functions. For example, orthopedics often use ankle-foot orthotics to assist children with hemiplegia, varus deformity, valgus deformity, and foot drop in walking training in order to achieve rehabilitation goals.

[0003] The ankle-foot orthosis used in the current technology often needs to be fixed to the patient's calf with a strap. Some patients need to take off the orthosis after wearing it for a certain period of time to massage their calf muscles to avoid redness or even bruising. This can easily lead to a shorter wearing time, which in turn reduces the patient's rehabilitation effect. Summary of the Invention

[0004] The purpose of this invention is to provide a reduction and fixation orthopedic correction device for clinical use in orthopedics, in order to solve the problem in the prior art that patients need to remove the device after a certain period of training to massage their calf muscles, which leads to a shortened wearing time and affects the patient's rehabilitation effect.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A reduction and fixation orthopedic correction device for clinical use in orthopedics includes a support plate, a base plate fixedly connected to the lower side wall of any side of the support plate, and fixing straps provided on both the support plate and the base plate, with the end of each fixing strap away from the support plate or the base plate being detachably connected to an adjacent side wall. A first airbag is fixedly connected to the lower side of the base plate, and a first one-way valve is provided on the first airbag. A plurality of first contacts are fixedly connected to the top wall of the first airbag, and second contacts corresponding to the first contacts are fixedly connected to the bottom wall of the first airbag. The support plate has an opening... The first chamber contains a sliding push plate, and a second airbag is fixedly connected to the bottom wall of the push plate. The second airbag communicates with the first airbag, and a second one-way valve is provided at the communication point. A first solenoid valve is also provided on the second airbag. Two first magnet blocks are symmetrically arranged on the push plate. A second magnet block corresponding to the first magnet block is slidably connected to the outer wall of the support plate near the bottom plate. Electromagnets are provided at both ends of the push plate. A number of batteries corresponding to the first contacts are provided in the support plate. The batteries are electrically connected to the corresponding first contacts, and the second contacts are electrically connected to the electromagnets.

[0006] It also includes a control system, which controls the operation of the electromagnet and the first solenoid valve.

[0007] Furthermore, the control system includes a pressure sensor, a controller, and several pressure sensors;

[0008] The pressure sensor is used to collect air pressure information inside the second airbag;

[0009] The pressure sensors are all used to collect information about the pressure applied by the patient to the base plate;

[0010] The controller is used to control the operation of the first solenoid valve based on the air pressure information and to control the operation of the electromagnet based on the pressure information.

[0011] Furthermore, a second chamber is formed inside the base plate, and several holes are formed in the top wall of the second chamber. The second chamber is connected to the second airbag, and a second solenoid valve is provided at the connection point.

[0012] Furthermore, the control system also includes a temperature sensor, which is used to collect the patient's temperature information. The controller controls the operation of the first solenoid valve and the second solenoid valve based on the temperature information.

[0013] Furthermore, the top wall of the push plate has a sliding groove, and the first magnet blocks slide in contact with the top wall of the push plate through the sliding groove, and the cross-section of the sliding groove is trapezoidal.

[0014] Furthermore, each of the second magnet blocks is covered with a protective sleeve made of elastic material.

[0015] Furthermore, the support plate is arc-shaped.

[0016] Furthermore, the top wall of the base plate has protrusions in the integrated imaging.

[0017] Furthermore, several baffles for sealing the holes are fixedly connected to the side walls of the holes.

[0018] Furthermore, a number of balls are rolled on the side wall of the push plate, and the push plate slides against the side wall of the first chamber through the balls.

[0019] The technical principles and beneficial effects of the above solution are as follows:

[0020] (1) This solution provides a first contact, a second contact, a battery and an electromagnet. During the patient's foot landing and foot lifting process, the number of the first and second contacts that are in contact is changed, thereby changing the magnetic force of the electromagnet, and thus changing the distance of the second magnet block. The distance of the second magnet block is constantly changed during the patient's foot landing and foot lifting process, thereby massaging the patient's calf muscles.

[0021] (2) By setting pressure sensors, the position of the patient's feet on the ground can be determined according to the location of the pressure sensor where the pressure information changes, so as to judge the patient's recovery status. When the patient's condition gradually recovers, the maximum current passing through the electromagnet is reduced and the movement frequency of the second magnet is reduced, so that this solution can adjust the massage intensity according to the patient's recovery status.

[0022] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0035] The following detailed description illustrates the specific implementation method:

[0036] Example 1

[0037] As attached Figure 1-8The following describes an orthopedic reduction and fixation device for clinical use: A support plate 3 is included. A base plate is adhered to the lower side wall of any side of the support plate 3. Fixing straps 4 are adhered to both the support plate 3 and the base plate, with the ends of the fixing straps 4 away from either the support plate 3 or the base plate detachably connected to the adjacent side wall via Velcro. A first airbag 2 is adhered to the lower side of the base plate. The first airbag 2 is equipped with a first one-way valve, preferably model Z-0039. Several first contact points 21 are adhered to the top wall of the first airbag 2, and second contact points 22 corresponding to the first contact points 21 are adhered to the bottom wall of the first airbag 2. A first chamber is formed within the support plate 3, and a pusher plate 32 slides within the first chamber. A second airbag 31 is adhered to the bottom wall of the pusher plate 32. The second airbag 31 communicates with the first airbag 2, and a second one-way valve is provided at the communication point, preferably model Z-0039. A first... The system includes a solenoid valve, preferably model FPDJ-05. Two first magnet blocks 33 are symmetrically arranged on the push plate 32. A second magnet block 34 corresponding to the first magnet blocks 33 is slidably fitted onto the outer wall of the support plate 3 near the base plate. Electromagnets 322 are provided at both ends of the push plate 32. A number of batteries 23 corresponding to the first contacts 21 are provided inside the support plate 3. The batteries 23 are electrically connected to their respective first contacts 21, and the second contacts 22 are all electrically connected to the electromagnets 322. The system also includes a control system for controlling the operation of the electromagnets 322 and the first solenoid valve. The control system includes a pressure sensor, a controller, and several pressure sensors. The pressure sensor is bonded and fixed to the inner wall of the second airbag 31. The controller is fixedly connected to the top wall of the first chamber by bolts. The pressure sensors are all fixedly connected to the top wall of the base plate by bolts. The pressure sensor, the first solenoid valve, the pressure sensors, and the electromagnets 322 are all electrically connected to the controller.

[0038] The specific implementation process is as follows: When using this device, the patient's foot is placed on the top wall of the base plate, and the back of the lower leg is close to the side wall of the support plate 3. By adjusting the fixing strap 4, the support plate 3 and the base plate are fixed to the patient's lower leg and foot, and then the device is activated.

[0039] When a patient wears this device for walking practice, when the patient steps down, the patient causes the base plate to compress the first airbag 2, allowing air from the first airbag 2 to enter the second airbag 31. Subsequently, the patient lifts their foot, and the first airbag 2 returns to its original position under its own elasticity, drawing outside air into it through the first one-way valve. This air is then compressed into the second airbag 31 the next time the patient steps down, causing the second airbag 31 to gradually inflate. This inflates the push plate 32, which in turn moves the first magnet 33 upwards. The first magnet 33, under its own magnetic force, moves the second magnet 34 upwards. Simultaneously, the air pressure sensor... The device continuously collects air pressure information from the second airbag 31. When the air pressure information is greater than the set value, the controller controls the first solenoid valve to open, and some of the gas in the second airbag 31 leaves through the first solenoid valve. At this time, the air pressure of the gas entering the second airbag 31 is insufficient to support the push plate 32. Under the action of gravity, the push plate 32 moves downward, causing the second magnet 34 to move downward at the same time. The second magnet 34 reciprocates to massage the back of the patient's calf. After the set time, the controller controls the first solenoid valve to close, and the air pressure in the second airbag 31 gradually increases, pushing the push plate 32 upward and driving the second magnet 34 to perform the next massage.

[0040] As the patient's foot steps down, the first contact 21 and the second contact 22 come into contact, connecting the circuit between the battery 23 and the electromagnet 322. The electromagnet 322, energized, generates magnetic force, attracting the adjacent first magnet block 33. This causes the first magnet block to slide against the top wall of the push plate 32, which in turn causes the second magnet block 34 to slide horizontally, increasing the massage range for the patient's calf muscles. Simultaneously, as the patient gradually lands from heel to toe, the number of contacts on the first and second contacts 21 and 22 increases, and the number of batteries connected to the circuit also gradually increases, thus increasing the connection... As the charge on electromagnet 322 increases, the magnetic force of the electromagnet rises, and the distance that the first magnet block 33 slides increases. This causes the massage range of the second magnet block 34 on the patient's calf muscles to gradually increase. As the patient gradually lifts their foot, from heel to toe, it gradually moves away from the ground, and the number of contacts between the first contact point 21 and the second contact point 22 gradually decreases. The number of batteries connected to the circuit decreases, and the magnetic force of the electromagnet decreases. Under the magnetic force of the two first magnet blocks 33 themselves, the two first magnet blocks 33 gradually return to their original position, causing the massage range of the second magnet block 34 on the patient's calf muscles to gradually decrease, thus completing one massage of the patient's leg.

[0041] During the patient's walking training while wearing this device, the pressure sensor continuously collects the pressure information applied by the patient to the base plate. Based on the position of the pressure sensor when the pressure information changes, the position of the patient's foot on the ground is determined. Patients with varus deformity, valgus deformity, and foot drop have different foot landing positions than normal people. For example, patients with varus deformity have their feet landing closer to the outer edge of the foot, while patients with valgus deformity have their feet landing closer to the inner edge of the foot. During training, when the pressure sensor position changes due to changes in pressure information (i.e., the patient's foot landing position changes), the patient's condition is relieved. At this time, the controller reduces the maximum current through electromagnet 322 to the set maximum rehabilitation current. As the current through electromagnet 322 gradually increases, once the current reaches the maximum rehabilitation current, although the number of batteries 23 connected to the circuit continues to increase, the current through electromagnet 322 no longer changes. The second magnet 34 no longer moves laterally to massage the patient's calf until the number of batteries 23 connected to the circuit begins to decrease. Only then does the current through electromagnet 322 begin to change again, causing the second magnet 34 to change its movement distance to massage the patient. This achieves the purpose of adjusting the massage frequency of the patient's calf according to the patient's rehabilitation condition.

[0042] Based on the above scheme, in order to reduce the discomfort of patients wearing this device during walking training and reduce the stuffiness of the patient's feet, a second chamber is opened in the base plate. The second chamber is connected to the second airbag 31, and a second solenoid valve is provided at the connection point. The preferred model of the second solenoid valve is FPDJ-05. Thus, when the patient's feet feel stuffy, the second solenoid valve can be opened, allowing some air in the second airbag 31 to enter the second chamber and be sprayed onto the patient's sole through the hole, thereby promoting air circulation in the patient's feet and reducing the temperature of the patient's feet through heat transfer.

[0043] Based on the above scheme, to further reduce patient discomfort during use, the control system also includes a temperature sensor. The temperature sensor is fixedly connected to the outer wall of the support plate 3 near the bottom plate by bolts. The preferred model of the temperature sensor is 718-272969-001. The temperature sensor is electrically connected to the controller. The temperature sensor is used to collect the patient's temperature information. The controller controls the operation of the first solenoid valve and the second solenoid valve according to the temperature information. Thus, during use, the temperature sensor continuously collects the temperature information of the patient's body surface. When the temperature information of the patient's body surface exceeds the set maximum temperature, the patient may feel stuffy. At this time, the controller closes the first solenoid valve and opens the second solenoid valve, so that the air in the second airbag 31 is sprayed onto the patient's feet through the second chamber, thereby reducing the temperature of the patient's feet. When the temperature information drops to the set minimum temperature, the controller controls the first solenoid valve to open and the second solenoid valve to close, so that the air in the second airbag 31 leaves again through the second solenoid valve.

[0044] Based on the above solution, in order to prevent the first magnet block 33 from detaching from the push plate 32 during the downward movement of the push plate 32, a sliding groove is opened on the top wall of the push plate 32. The first magnet block 33 slides and engages with the top wall of the push plate 32 through the sliding groove, and the cross-section of the sliding groove is trapezoidal. Thus, during the movement of the push plates 32 towards each other, the first magnet block 33 can move downward under the combined action of its own weight and the force of the sliding groove, thereby preventing the first magnet block 33 from detaching from the push plate 32 and affecting the massage effect of the device on the patient.

[0045] Based on the above scheme, in order to reduce the influence of the magnetic force between the second magnet blocks 34 on the movement of the second magnet blocks 34, each of the second magnet blocks is wrapped with a protective sleeve 341 made of elastic material. Thus, the protective sleeve 341 weakens the magnetism between the second magnet blocks 34. When the two first magnet blocks 33 drive the two second magnet blocks 34 to separate, it is not easily affected by the magnetic force between the two magnet blocks. At the same time, it can also reduce the pressure of the second magnet blocks 34 on the patient's calf through its own elastic deformation, further reducing the discomfort of this device.

[0046] Based on the above solution, in order to reduce the discomfort caused to the patient by the support plate 3, the support plate 3 is made into an arc shape. As a result, the support plate 3 can better fit the shape of the patient's lower leg, increase the contact area between the support plate 3 and the patient's lower leg, and thus reduce the pressure exerted by the support plate 3 on the patient's lower leg.

[0047] Based on the above scheme, in order to enhance the corrective effect of the device and further reduce the discomfort during the use of the device, a protrusion 11 is integrally formed on the bottom and top walls. Thus, when the patient wears the device, the arch of the foot fits against the protrusion 11, so that the protrusion 11 provides certain support for the patient's arch and increases the contact area between the patient's foot and the bottom plate, thereby reducing the pressure on the patient's foot.

[0048] Based on the above scheme, in order to improve the user experience of this device and reduce the discomfort of the patient's feet during walking training, several baffles 12 for sealing the holes are glued and fixed to the side walls of the holes. Thus, after the air in the second airbag 31 enters the second chamber, it cannot be sprayed onto the patient's feet immediately through the holes. The air pressure in the second chamber gradually increases. When the air pressure in the second chamber reaches a certain value, the baffles 12 flip under the action of air pressure, and the gas in the second chamber can be sprayed onto the patient's feet. At this time, the speed of the sprayed gas increases, thereby massaging the patient's feet and relieving the discomfort caused by walking training.

[0049] Based on the above solution, in order to avoid the push plate 32 being unable to return to its original position under gravity due to friction during the descent process, thus affecting the subsequent massage effect, a number of ball bearings 321 are rolledly connected to the side wall of the push plate 32. The push plate 32 slides against the side wall of the first chamber through the ball bearings 321. Thus, during the movement of the push plate 32, the ball bearings 321 can convert the sliding friction between the push plate 32 and the side wall of the first chamber into rolling friction, thereby reducing the impact of friction on the descent process of the push plate 32.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention.
