Description

Technical Field

[0001] The present invention relates to the technical field of lumbar fixation, and particularly relates to a multifunctional fixation device for lumbar disc herniation. Background Art

[0002] The lumbar spine, as a key component of the spine located in the waist, is an important load-bearing and movement structure of the human body. Under the influence of factors such as age growth, long-term lumbar strain, and trauma, the annulus fibrosus of the lumbar disc may rupture. Due to the internal pressure, the nucleus pulposus will protrude from the rupture. Once the protruding disc compresses the sciatic nerve, it is likely to cause radiating pain in the lower limbs. When the condition is severe, patients often need to undergo surgery for treatment; After surgery, to assist the patient's recovery, a fixation device is often used to support the waist. Such a fixation device can provide external support, share part of the body weight, effectively reduce the pressure on the lumbar spine, create a safe condition, and facilitate the patient to carry out lumbar muscle exercise and functional recovery training. For example, a multifunctional fixation device for lumbar disc herniation disclosed in the publication number CN105919708B can provide reliable fixation for the waist of postoperative patients.

[0003] In actual application scenarios, common multifunctional fixation devices have many problems. Their so-called multifunction often only adds auxiliary functions such as stretching and massage on the basis of fixing the patient's waist. However, these auxiliary functions are not unique to this device, and patients can also achieve them by using other tools when lying flat. From the perspective of the support and correction effect, due to the addition of these unnecessary functions, such devices have increased unnecessary weight. The overweight device not only cannot provide good support for the waist, but also is difficult to accurately fix and correct the lumbar spine at a fixed point. From the perspective of cost and usage impact, the redundancy of functions leads to an increase in the manufacturing cost of the device. Worse still, the overweight device hinders the patient's rehabilitation exercise and affects the rehabilitation effect. Moreover, when the patient accidentally falls, the weight of the device is very likely to cause secondary injury to the wound. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a multifunctional fixation device for lumbar disc herniation, which can effectively solve the problems that the prior art cannot fix and correct the lumbar spine at a fixed point and cause secondary injury to the wound.

[0009] Preferably, the arc-shaped grooves and the rectangular grooves are at the same height and penetrate through the inner wall of the rectangular grooves. The communicating pipe is communicated with the arc-shaped hole.

[0010] Preferably, it further includes a monitoring and triggering mechanism. The monitoring and triggering mechanism includes an air pump fixed to the bottom wall of the back fixing plate.

[0023] Furthermore, in order to complete the fixation of the patient's lumbar spine, the following settings are made, as Figure 6 and Figure 7As shown in the figure, the pressurizing orthopedic mechanism 4 includes a first U-shaped tube 41 fixed inside the back fixing plate 31. A connecting pipe 42 is connected to the middle of the outer surface of the first U-shaped tube 41. A pressurizing assembly 43 is fixed between the upper and lower ends of the first U-shaped tube 41. Sealing plates 44 are symmetrically and elastically connected to the outer surface of the pressurizing assembly 43. Permanent magnets 45 are symmetrically embedded at one end of the sealing plate 44 close to the pressurizing assembly 43. An electromagnetic block 46 is provided on the side of the permanent magnet 45 close to the pressurizing assembly 43. The permanent magnet 45 and the electromagnetic block 46 repel each other magnetically.

[0024] For further illustration, the following settings are made to fix the patient's lumbar spine at a specific point, as Figure 8 As shown in the figure, the pressurizing assembly 43 includes a support plate 431 fixed inside the back fixing plate 31. An arc-shaped hole 432 is penetrated through the upper end of the support plate 431. Electric telescopic rods 433 are symmetrically fixed in the arc-shaped hole 432. Sealing blocks 434 are fixed at one ends of the two electric telescopic rods 433 close to each other. A number of rectangular grooves are arrayed at one end of the support plate 431 close to the first U-shaped tube 41. Pressurizing air bags 435 are slidably connected in the rectangular grooves. A number of arc-shaped grooves 436 are arrayed on the inner wall of the arc-shaped hole 432. The arc-shaped grooves 436 and the rectangular grooves are at the same height and penetrate through the inner wall of the rectangular grooves. The connecting pipe 42 is connected to the arc-shaped hole 432.

[0025] For further illustration, the following settings are made to cooperate with the pressurizing orthopedic mechanism 4 to protect the patient, as Figure 9 As shown in the figure, the monitoring trigger mechanism 5 includes an air pump 51 fixed to the bottom wall of the back fixing plate 31. The input end of the air pump 51 penetrates through the inner wall of the back fixing plate 31. The output end of the air pump 51 is fixed with a fixed pipe 52. A second U-shaped tube 53 is fixed to the outer surface of the fixed pipe 52. A blocking block 54 is fixed in the fixed pipe 52. A detection assembly 55 is provided below the blocking block 54. A ventilation pipe 56 communicating with the fixed pipe 52 is provided between the blocking block 54 and the detection assembly 55. The two upper ports of the ventilation pipe 56 are respectively connected to the first buffer air bags 32 on the same side. The upper end of the fixed pipe 52 is connected to the first U-shaped tube 41; Specifically, start the air pump 51 to draw external air into the fixed tube 52, then flow through the second U-shaped tube 53 into the first U-shaped tube 41. Then, open the solenoid valve in the connecting tube 42 to allow the air flowing into the connecting tube 42 to enter the arc-shaped holes 432. The air will enter each rectangular groove from the arc-shaped groove 436. The air entering the rectangular groove will flow into the pressurizing airbag 435. The volume of the pressurizing airbag 435 is increased by the air pressure. Since the elastic member 36 is in contact with the outer surface of the pressurizing airbag 435, when the volume of the pressurizing airbag 435 increases, it will push the fixed block 34 towards the direction close to the patient's back. While driving the fixed bead 35 to move, the fixed block 34 will also squeeze the elastic member 36 to make it contract. By using the air pressure in the pressurizing airbag 435 and the contact between the fixed bead 35 and the patient's lumbar vertebra, the device can correct and fix the patient's lumbar vertebra.

[0026] For further explanation, in order to monitor the patient's state and prevent accidental touch, the following settings are made. As Figure 10 shown, the detection component 55 includes a sealing ring 551 fixed in the connecting tube 42. An open groove 552 is provided on the inner wall of the sealing ring 551. A hollow column 553 is slidably connected in the sealing ring 551. The hollow column 553 is elastically connected to the shielding block 54. Activity grooves 554 are symmetrically provided on the outer surface of the hollow column 553. A limiting block 555 is rotatably connected in the activity groove 554. A movable plate 556 is slidably connected to the top wall of the activity groove 554. The movable plate 556 is elastically connected to the inner wall of the activity groove 554. The limiting block 555 and the movable plate 556 are rotatably connected. A counterweight ball 557 is provided in the hollow column 553. The counterweight ball 557 is fixedly connected to the two movable plates 556 by a connecting rope. A tapered ring 558 is fixed to the inner wall of the hollow column 553. The tapered ring 558 is located below the counterweight ball 557. A telescopic rod is provided between the shielding block 54 and the hollow column 553, which can limit the hollow column 553 to only move vertically up and down; It should be noted that when the patient is in an upright state, the counterweight ball 557 will move downward under the action of gravity, and then pull the two movable plates 556 to move towards each other through the connecting rope. During the movement of the movable plate 556, it will drive the two limiting blocks 555 to rotate into the activity groove 554, so that the limiting blocks 555 no longer limit the hollow column 553. When the patient suddenly falls while walking, the gyroscope sensor in the PLC controller can detect the acceleration generated during the fall, and then start the air pump 51 at its maximum power to draw a large amount of air from the outside into the fixed tube 52. At this time, the air entering the fixed tube 52 will push the entire hollow column 553 upward, so that the air can flow through the sealing ring 551 into the ventilation tube 56, and then enter the first buffer airbag 32, the second buffer airbag 33 and the protective airbag 13 through the ventilation tube 56.

[0027] The working principle of the present invention is as follows: Lift the lying patient to make them lie on their side, then place the back fixing frame 3 under the patient, let the patient lie flat again, and then place the front fixing frame 1 on the patient's abdomen. The device can be fixed on the patient's body through Velcro. By manually squeezing the pressure ball 14, air is filled into the two tightening air bags 12 (a one-way valve is provided in the pressure ball 14, and when continuously squeezed, air can be injected into the tightening air bag 12 through the one-way valve. The tightening air bag 12 is provided with an exhaust structure and a sealing structure, and when the device needs to be disassembled from the patient, the air in the tightening air bag 12 can be discharged), ensuring that the device can fit tightly on the upper body of the patient without loosening. Cooperating with the front fixing plate 11 and the back fixing plate 31 made of hard materials to fix the patient's lumbar spine, effectively restricting the flexion, extension, lateral flexion and rotation of the lumbar spine, providing stable fixation, reducing the relative displacement and pressure between lumbar vertebrae, thereby reducing the irritation and compression of tissues such as intervertebral discs, nerve roots and spinal cord; When the lumbar spine needs to be corrected, start the air pump 51 to draw external air into the fixing tube 52, then flow through the U-shaped tube II 53 into the U-shaped tube I 41, and then open the solenoid valve in the connecting tube 42 to make the air flowing into the connecting tube 42 enter the arc-shaped hole 432. The air will enter each rectangular groove from the arc-shaped groove 436. The air entering the rectangular groove will flow into the pressure air bag 435. The volume of the pressure air bag 435 is increased by the air pressure. Since the elastic member 36 is in contact with the outer surface of the pressure air bag 435, when the volume of the pressure air bag 435 increases, it will push the fixing block 34 to move towards the patient's back. While driving the fixing bead 35 to move, the fixing block 34 will also squeeze the elastic member 36 to make it contract; Utilize the air pressure in the pressure air bag 435 and the fixing bead 35 contacting the patient's lumbar spine to enable the device to correct and fix the patient's lumbar spine. The fixing block 34 and the fixing bead 35 in contact with the lumbar spine can provide restraint and support around the waist, enhance the stability of the lumbar spine, and prevent the aggravation of pain or the deterioration of the condition caused by lumbar spine instability. By controlling the positions of the two sealing blocks 434, the fixing position of the fixing block 34 on the patient's lumbar spine can be adjusted (start the two electric telescopic rods 433 to extend, which can drive the two sealing blocks 434 to move towards each other. During the movement of the sealing blocks 434, the arc-shaped groove 436 passed through can be hermetically sealed, so that the air entering the arc-shaped hole 432 through the connecting tube 42 cannot enter the rectangular groove through the arc-shaped groove 436, and the fixing block 34 and the fixing bead 35 at the same height cannot move), and the lumbar spine can be fixed and corrected in a fixed-point and positioned manner through adjustment, and at the same time, the postoperative wound on the patient's back can be avoided; When the postoperative wound of the patient is in the middle, the solenoid valve in the connecting pipe 42 can be closed in the initial state of the device. Then, start the two electric telescopic rods 433 to drive the two sealing blocks 434 to move towards each other. Wait until they move to a suitable position (that is, let the wound be between the two sealing blocks 434, and the distance between the two sealing blocks 434 is slightly larger than the height of the wound). Then, start the air pump 51 to draw external air into the fixed pipe 52. The air will flow through the second U-shaped pipe 53 into the first U-shaped pipe 41, and then enter the arc-shaped holes 432 from the two ports of the first U-shaped pipe 41. At this time, the air will still enter each rectangular groove from the arc-shaped groove 436. By increasing the volume of the pressurizing airbag 435, the fixed block 34 and the fixed beads 35 are pushed to move. However, when the air enters the arc-shaped holes 432, it cannot enter between the two sealing blocks 434. That is to say, the air cannot push the fixed block 34 and the fixed beads 35 at the wound. Without touching the patient's wound, the fixation and correction work on other parts of the patient's lumbar spine can still be carried out; And by energizing the electromagnet 46 through the PLC controller, the electromagnet 46 can generate magnetism, and the end faces of the permanent magnet 45 and the electromagnet 46 in contact with each other have opposite magnetic poles. After the electromagnet 46 generates magnetism, it will push the permanent magnet 45 to move towards the side away from the support plate 431. The permanent magnet 45 will drive the sealing plate 44 to move at the same time. When the sealing plate 44 no longer touches the support plate 431, the rectangular groove will be in an airtight communication state with the back fixing plate 31. At this time, the contracted elastic member 36 will drive the fixed block 34 and the fixed beads 35 to reset, so that the fixed block 34 squeezes the pressurizing airbag 435 during the movement, causing the air in the rectangular groove and the pressurizing airbag 435 to be discharged from the arc-shaped groove 436 into the back fixing plate 31. At this time, the PLC controller stops energizing the electromagnet 46, and the sealing plate 44 elastically connected to the support plate 431 will drive the permanent magnet 45 to reset. Continuously start the air pump 51 to introduce air into the rectangular groove, and at the same time, make the PLC controller energize and de-energize the electromagnet 46 (repeating this way). It can make the arc-shaped groove 436 drive the fixed block 34 and the fixed beads 35 to move back and forth, continuously pressing on the patient's lumbar spine, reducing the tension and spasm of the muscles around the injured lumbar spine. When the muscles are in a relaxed state, it can effectively reduce the pain caused by muscle traction. At the same time, it can also promote the local blood circulation of the lumbar spine and help maintain the physiological curvature of the lumbar spine, enhancing the stability of the lumbar spine in all directions; A few days after the operation, the patient does not need to stay in bed all the time and can get up and move appropriately. When the patient is in an upright state, the counterweight ball 557 will move downward under the action of gravity, and then pull the two movable plates 556 to move towards each other through the connecting rope. During the movement of the movable plate 556, it will drive the two limit blocks 555 to rotate into the movable groove 554, so that the limit blocks 555 no longer limit the hollow column 553. When the patient suddenly falls while walking, the gyroscope sensor in the PLC controller can detect the acceleration generated during the fall, and then start the air pump 51 at maximum power to draw a large amount of air from the outside into the fixed tube 52. At this time, the air entering the fixed tube 52 will push the entire hollow column 553 upward, so that the air can flow through the sealing ring 551 into the ventilation pipe 56, and then enter the first buffer airbag 32, the second buffer airbag 33 and the protection airbag 13 through the ventilation pipe 56. Through the reasonable setting of the first buffer airbag 32 and the second buffer airbag 33, the lumbar spine of the patient can be protected, and even if the patient suddenly falls while walking, the lumbar spine will not be sprained and cause secondary injury to the patient; When the patient falls, it is necessary to check and care for the patient. At this time, manually release the air in the first buffer airbag 32, the second buffer airbag 33 and the protection airbag 13, and the patient can be normally dressed. After the patient returns to the lying state, before that, the air pump 51 will stop injecting air into the fixed tube 52, so that the hollow column 553 will move downward under the action of gravity. The counterweight ball 557 will reset under the action of the elastic connection between the movable plate 556 and the movable groove 554 and continue to limit the hollow column 553. When the patient is in a side-lying state, since the inner wall of the movable plate 556 and the movable groove 554 is elastically connected, and there is a certain frictional force between the conical ring 558 and the counterweight ball 557, even if the patient is in a sitting position against the wall, the counterweight ball 557 needs to overcome the frictional force with the conical ring 558 and the elastic force between the inner wall of the movable plate 556 and the movable groove 554. Even if the inclination angle is large, the counterweight ball 557 will only move downward a limited distance and will not let the limit block 555 release the limit on the hollow column 553, which can ensure that the device will not be accidentally touched when the patient lies down.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
