Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of thoracolumbar orthosis, in particular to a hardness-adjustable segmented thoracolumbar orthosis after operation. BACKGROUND

[0002] The thoracolumbar orthosis is a special medical auxiliary device, mainly used in the rehabilitation process after thoracic vertebral fracture or thoracic surgery. Its functions mainly include protection, fixation and correction, etc., helping to limit the thoracic movement, avoid excessive stress on the fracture site, and promote the recovery of the disease.

[0003] At present, after thoracolumbar surgery, the operation site of the patient needs to be stabilized, and the thoracolumbar orthosis can provide good protection and stability. The thoracolumbar orthosis is often divided into dorsal orthosis and ventral orthosis. The postoperative patient is first made to lie on one side, the dorsal orthosis is attached to the back of the postoperative patient, the orthosis is slightly moved to make the patient's back as close as possible, then the patient is turned over to wear the ventral orthosis, and the two parts of the orthosis are fixed by using magic tape.

[0004] However, the commercial thoracolumbar orthosis on the market is designed to meet the needs of independent lumbar or thoracic vertebrae, and the strength is fixed. For long-term fixation of the thoracolumbar orthosis, the best method is to customize it in the hospital, but the customization is more suitable for the patient. As for the strength, it remains consistent, and different patients have different spinal segments. The required fixation strength during surgery is different. Sometimes it needs to be fixed firmly, and sometimes it needs to be fixed with elasticity. However, the existing orthosis cannot change the strength, so the orthosis cannot be well adapted to the actual situation during use, affecting the use of the patient during and after the operation. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a hardness-adjustable segmented thoracolumbar orthosis after operation, so as to solve the problem that the existing orthosis cannot change the strength, so the orthosis cannot be well adapted to the actual situation during use, affecting the use of the patient during and after the operation.

[0015] Optionally, the clamping block is in U-shaped plastic material and is in hollow state in the middle part, and the side surface is fixedly connected to the outer surface of the moving belt and is opposite to the position of the support block.

[0016] Optionally, the tooth track is fixedly connected to the inner surface of the moving belt.

[0017] Optionally, the weakening part is arranged at the middle part of the steel wire and the position extending outward from the middle part.

By manually grabbing any position of the outer surface of the moving belt and starting to pull down or lift up, the tooth track inside the moving belt and the gear rack on the gear begin to mesh and transmit. In this state, the brace is suitable for patients who need hardness, and the bearing plate is directly clamped in the position of the clamping block. At this time, the gear is limited by the pressing column and the limiting hook, and the moving belt cannot mesh with the gear rack on the gear, so it cannot drive the moving belt to transmit. The position of the clamping block is stable, so the supporting effect of the elastic rope can be further assisted, and the comfort of wearing the thoracolumbar brace as a whole is improved.

[0045] As Figures 1 to 14As shown, the embodiment of the present application provides a hardness-adjustable segmented thoracolumbar postoperative brace, which comprises a thoracolumbar brace 1 and an auxiliary adjusting assembly, a connecting column 2 is installed in the middle position of the thoracolumbar brace 1, a bearing plate 3 is attached to the middle part of the thoracolumbar brace 1, an elastic rope 4 is attached to the surface of the bearing plate 3, a connecting plate 5 is fixedly connected to the middle part of the thoracolumbar brace 1, the connecting plate 5 is symmetrically arranged on both sides of the bearing plate 3, i.e. the connecting plate 5 is symmetrically arranged on both sides of the opening of the thoracolumbar brace 1, a steel wire 6 is installed at the bottom of the thoracolumbar brace 1, and a reinforcing plate 7 is clamped in the inner cavity of the thoracolumbar brace 1.

[0046] The auxiliary adjusting assembly is used to change the strength of the thoracolumbar brace 1, and the auxiliary adjusting assembly is connected with the thoracolumbar brace 1. The thoracolumbar brace 1, the bearing plate 3, and the elastic rope 4 are existing structures. The thoracolumbar brace 1 is divided into two parts, one part is a dorsal brace, and the other part is a ventral brace. The middle part of the thoracolumbar brace 1 is an open position, and the inner cavity of the bottom end of the thoracolumbar brace 1 is a slot, which has a slight deformation ability. The two ends of the bearing plate 3 are provided with clamping grooves. The connecting plate 5 is made of plastic material and is fixedly connected to the opening position of the middle part of the thoracolumbar brace 1. The connecting plate 5 and the bearing plate 3 are arranged perpendicular to each other. The side surface of the connecting column 2 is fixedly connected to the surface of the connecting plate 5 and penetrates the inner cavity of the connecting plate 5. The steel wire 6 is made of metal material and is fixedly connected to the bottom of the thoracolumbar brace 1. The overall shape of the steel wire 6 is consistent with the shape of the bottom end of the thoracolumbar brace 1. The reinforcing plate 7 is an existing structure and can be made of metal or hard material. The reinforcing plate 7 is clamped in the inner cavity of the thoracolumbar brace 1 and is limited in the inner cavity of the thoracolumbar brace 1 by the steel wire 6.

[0047] In the above structure, when in use, the patient first lies on the bed, then turns the patient's body to one side, and leans to the left side to turn over, the dorsal brace is first worn on the back of the patient, and then the patient is normally laid flat. Start wearing the ventral brace, when wearing, whether to improve stability can be determined according to the actual size of the patient's chest and waist, when in use, by changing the position between the bearing plate 3 and the elastic rope 4, the patient's chest and waist position and the fitting effect between the thoracolumbar brace 1 are different, and the size of the patient's iliac bone part is also different, by changing the actual position of the steel wire 6, the bottom of the thoracolumbar brace 1 can be bent, and at the same time the reinforcing plate 7 is integrally clamped in the inner cavity of the bottom end of the thoracolumbar brace 1 from bottom to top, and cooperates with the steel wire 6 to strengthen the stability of the reinforcing plate 7, through the auxiliary adjusting assembly, the overall fitting effect of the thoracolumbar brace 1 on the patient can be further improved, when wearing, the overall strength of the thoracolumbar brace 1 can be changed according to the different use environment and the patient's own condition, and because the size of the patient's iliac bone is also different, the position of the reinforcing plate 7 can be clamped and stabilized by adjusting the steel wire 6, so that the patient can be more flexible and variable when wearing, the overall adaptability and flexibility of the thoracolumbar brace 1 are improved, and the ability to adjust the strength of the middle part of the thoracolumbar brace 1 is also improved, so that the brace can be well adapted when in use, and the use of the patient during and after the operation is ensured.

[0048] As shown in Figures 10 to 11 , the auxiliary adjusting assembly comprises a gear 201 fitted in the middle opening of the thoracolumbar brace 1, an extension column 202 fixedly connected to the end of the gear 201 away from the middle of the thoracolumbar brace 1, a pressing column 203 slidably connected in the inner cavity of the extension column 202, a limiting hook 204 fixedly connected to the surface of the pressing column 203, the limiting hook 204 being circumferentially arranged around the pressing column 203, a protruding part 205 being formed at the bottom end of the limiting hook 204 close to the outer surface of the gear 201, one end of the gear 201 being a protruding column, the other end being a groove, the surface being a rack, the protruding column being rotatably connected to the surface of the connecting plate 5 (as Figure 9 ), the extension column 202 being fixedly connected to the center position of the groove of the gear 201 and extending a certain distance, the pressing column 203 being slidably connected in the groove and on the outer surface of the extension column 202, a slot being formed in the middle of the pressing column 203, the size of the slot being consistent with the size of the extension column 202, and when the pressing column 203 is pressed to the limit, the inner wall of one end of the slot abuts against the end of the extension column 202.

[0049] The limiting hook 204 is made of plastic material, one end of which is fixedly connected to the end surface of the pressing column 203 away from the extension column 202, the other end being open, and fitted with the outer surface of the gear 201, the protruding part 205 being formed at the bottom end of the open end of the limiting hook 204 and fitted with the outer surface of the gear 201.

[0050] In the above structure, the gear 201 can complete self-rotation. The self-rotation is achieved by relying on the raised column between the gear 201 and the connecting plate 5. The raised column is on the gear 201. When the gear 201 rotates, the position of the pressing column 203 and the limiting hook 204 is away from the extension column 202. Figure 11 It is observed that when the gear 201 rotates, the pressing column 203 and the limiting hook 204 are away from the positions of the gear 201 and the extension column 202, so that the gear 201 has no obstacles and can complete its autonomous rotation. When the gear 201 needs to stop rotating for limiting, the pressing column 203 is pressed to make the extension column 202 engage with the slot. At this time, the extension column 202 completely enters the slot, and the pressing column 203 is pushed hard, so that the limiting hook 204 will begin to slide on the outer surface of the gear 201, gradually approaching the rack fixed on the outer surface of the gear 201, and making the open end of the limiting hook 204 fit with the gap between the rack of the gear 201, that is, the two adjacent An open end of a limiting hook 204 is inserted between the racks, which prevents the rack of the gear 201 from fitting with other parts and preventing normal rotation to achieve the limiting effect. It is worth mentioning that the pressing column 203 and the limiting hook 204 are removable, that is, when the gear 201 is in normal operation, the pressing column 203 and the limiting hook 204 are not connected to the side of the gear 201. When the gear 201 needs to be limited, the pressing column 203 and the limiting hook 204 can be connected to the gear 201. The above process can ensure the flexibility of the use of the gear 201, which can be changed according to actual conditions, thereby improving the convenience of user adjustment.

[0051] like Figures 6 to 9As shown, the surface of the adapter plate 5 is attached with a moving belt 501, one side of the adapter plate 5 is uniformly attached with a supporting block 502 along the length direction of the adapter plate 5, one side of the adapter plate 5 is fixedly connected with a limiting plate 503, the limiting plate 503 is perpendicular to the surface of the adapter plate 5, the outer surface of the moving belt 501 is fixedly connected with a clamping block 504, both sides of the moving belt 501 are fixedly connected with a gear track 505, the moving belt 501 is made of plastic material, one side of which is attached to the surface of the adapter plate 5 and has a certain friction, the end of the supporting block 502 is fixedly connected to the side of the moving belt 501, which is L-shaped, and the side of the supporting block 502 close to the surface of the moving belt 501 is designed with a clamping spike, which can firmly fix the elastic rope 4, the limiting plate 503 is fixedly connected to the surface of the adapter plate 5, the limiting plate 503 is distributed in a stepped manner, the inner side part fixedly connected with the adapter plate 5 is smaller in size than the inner ring of the moving belt 501, and the outer side part attached to the outer surface of the moving belt 501 is larger in size than the outer ring of the moving belt 501, and the moving belt 501 will not fall off because the outer side part of the limiting plate 503 is attached to the outer surface of the moving belt 501, the limiting plate 503 prevents the moving belt 501 from falling sideways, and the limiting plate 503 plays a blocking role but does not resist the moving belt 501. The clamping block 504 is made of plastic material and is U-shaped, and a slot is formed in the middle of the clamping block 504, the both ends of the bearing plate 3 are provided with clamping grooves, the size of the clamping grooves is consistent with the size of the clamping block 504, and the position of the bearing plate 3 can be fixed by clamping the both ends of the bearing plate 3 in the clamping block 504 during use, and the gear track 505 is fixedly connected to the inner surface of the moving belt 501 and is arranged in a curved array on the inner surface of the moving belt 501, which is matched with the gear rack on the gear 201.

[0052] In the above structure, in the initial state, the moving belt 501 is attached to the surface of the adapter plate 5 and the limiting plate 503, by manually grabbing any position of the outer surface of the moving belt 501 and starting to pull down or lift up, the gear track 505 inside the moving belt 501 and the gear rack on the gear 201 begin to mesh and transmit, then the supporting block 502 and the clamping block 504 on the moving belt 501 begin to change position and move synchronously with the movement of the moving belt 501, such as Figure 2 The bearing plate 3 in the middle is located on the inner side of the elastic rope 4, and this state of the brace is suitable for patients who need hardness, which is also the initial state of the brace, according to Figure 9The left side of the moving belt 501 is regarded as the inner side, and the right side of the moving belt 501 is regarded as the outer side, that is, in the initial state, the patient with certain requirements for the hardness of the brace, and at this time, the bearing plate 3 is located on the inner side of the moving belt 501, and the supporting block 502 is located on the outer side of the moving belt 501, wherein the bearing plate 3 is detachable and needs to be manually clamped in the position of the clamping block 504, after the gear 201 is limited by the pressing column 203 and the limiting hook 204, the moving belt 501 cannot engage with the rack on the gear 201, so that the gear 201 and the gear 201 are no longer engaged and driven, and the moving belt 501 no longer changes, and remains in a fixed state, which also ensures that the position of the clamping block 504 and the bearing plate 3 is fixed, and for the same reason, if the patient does not need to use a brace with high hardness, continue to drive the moving belt 501 to change through the engagement of the gear 201 and the rack on the gear 201, so that the clamping block 504 gradually changes from the original initial position, that is, the inner side of the moving belt 501, to the outer side of the moving belt 501, and because the supporting block 502 is also fixed on the moving belt 501, the supporting block 502 will be synchronously driven to gradually locate on the inner side of the moving belt 501, and the supporting block 502 is fixed with the elastic rope 4, in this state, the back of the patient directly contacts the elastic rope 4, and the brace conforms to the elastic effect, it is worth mentioning that when the clamping block 504 is located on the outer side of the moving belt 501, the clamping block 504 and the bearing plate 3 are detachably connected, and the bearing plate 3 can be selected according to the actual situation of the back of the patient, specifically, if the weight of the patient is greater than the bearing capacity of the elastic rope 4, the bending degree of the elastic rope 4 will be large, and the supporting capacity of the back will decrease, if the bearing plate 3 is installed, the elastic rope 4 will abut against the bearing plate 3 under the continuous action, so as to further assist the supporting effect of the elastic rope 4, and improve the comfort of the whole thoracolumbar brace 1, and vice versa.

[0053] As shown in Figures 12 to 14 The surface of the steel wire 6 is provided with a weakening portion 601, the weakening portion 601 is a plurality of, the shape of the steel wire 6 is matched with the bottom end of the thoracolumbar brace 1, the steel wire 6 is fixedly connected to the bottom end of the thoracolumbar brace 1, and the material of the bottom end of the thoracolumbar brace 1 is different from that of the middle and upper end of the thoracolumbar brace 1, the bottom end has a certain deformation capacity, the weakening portion 601 is arranged on the surface of the steel wire 6 and is unevenly distributed, in the above structure, the position of the steel wire 6 is manually adjusted, so that the steel wire 6 and the bottom end of the thoracolumbar brace 1 are deformed, and because the steel wire 6 can be plastic, the state after deformation can be ensured, manual adjustment around the weakening portion 601 can improve the adaptability of the bottom of the thoracolumbar brace 1 to the iliac position of the patient, and the fine adjustment of the steel wire 6 and the weakening portion 601 can change the strength according to the actual situation of the patient, which is beneficial to the wearing and recovery of the patient.

[0054] The working process of the technical scheme provided by the application is as follows:

[0055] In use, the patient first lies on the bed, then turns the patient's body to one side, tilts the patient's body to the left side, turns over, wears the dorsal brace on the back of the patient, and then lies normally. Start wearing the ventral brace, when wearing, you can decide whether to improve stability according to the actual size of the patient's thoracolumbar spine, when in use, by changing the position between the bearing plate 3 and the elastic rope 4, the patient's thoracolumbar position and the fit between the thoracolumbar brace 1 are different, and the size of the patient's iliac bone part is also different, by changing the actual position of the steel wire 6, the bottom of the thoracolumbar brace 1 can be bent, and the reinforcing plate 7 is clamped in the inner cavity of the bottom end of the thoracolumbar brace 1 from bottom to top, and cooperates with the steel wire 6 to strengthen the stability of the reinforcing plate 7. Through the auxiliary adjusting assembly, the overall fitting effect of the thoracolumbar brace 1 on the patient can be further improved. When wearing, the overall strength of the thoracolumbar brace 1 can be changed according to the different use environment and the patient's own condition, and because the size of the patient's iliac bone is also different, the position of the reinforcing plate 7 can be clamped and stabilized by adjusting the steel wire 6, so that the patient can be more flexible and variable when wearing, improve the overall adaptability and flexibility of the thoracolumbar brace 1, and also improve the ability to adjust the strength of the middle part of the thoracolumbar brace 1, so that the brace can be well adapted during use, and ensure that the patient can use it during and after the operation.

[0056] The gear 201 can rotate, and the rotation is achieved by the protruding column between the gear 201 and the connecting plate 5. The protruding column is on the gear 201, and when the gear 201 rotates, the positions of the pressing column 203 and the limiting hook 204 are away from the extension column 202, which can be achieved by Figure 11When the gear 201 rotates, the pressing column 203 and the limiting hook 204 are away from the gear 201 and the extension column 202, so that the gear 201 can rotate freely. When the gear 201 needs to be stopped, the pressing column 203 is pressed to make the extension column 202 engage into the slot hole. At this time, the extension column 202 completely enters the slot hole, and the pressing column 203 is pushed hard, so that the limiting hook 204 starts to slide on the outer surface of the gear 201, gradually approaches the rack fixed on the outer surface of the gear 201, and makes the open end of the limiting hook 204 adapt to the gap between the racks of the gear 201, that is, one open end of the limiting hook 204 is inserted between two adjacent racks, so that the racks of the gear 201 cannot adapt to other parts, and cannot rotate normally to complete the limiting effect. It is worth mentioning that the pressing column 203 and the limiting hook 204 can be removed, that is, when the gear 201 is normally used, the pressing column 203 and the limiting hook 204 are not engaged on the side of the gear 201. When the gear 201 needs to be limited, the pressing column 203 and the limiting hook 204 are engaged with the gear 201. The above process can ensure the flexibility of the gear 201, which can be changed according to the actual situation.

[0057] In the initial state, the moving belt 501 is attached to the surface of the connecting plate 5 and the limiting plate 503. By manually grabbing any position of the outer surface of the moving belt 501 and starting to pull down or lift up, the tooth track 505 inside the moving belt 501 and the rack on the gear 201 start to mesh and transmit. Then the supporting block 502 and the clamping block 504 on the moving belt 501 start to change position and move synchronously with the movement of the moving belt 501, as shown in Figure 2 The middle bearing plate 3 is located on the inner side of the elastic rope 4. This state of the brace is suitable for patients who need hardness, and is also the initial state of the brace. According to the needs of the patient, the elastic rope 4 can be replaced by a spring or a spring steel wire, and the length of the elastic rope 4 can be adjusted according to the needs of the patient. Figure 9The left side of the moving belt 501 is defined as the inner side, and the right side of the moving belt 501 is defined as the outer side, that is, in the initial state, the patient with certain requirements for the hardness of the brace, and at this time, the bearing plate 3 is located on the inner side of the moving belt 501, and the supporting block 502 is located on the outer side of the moving belt 501, wherein the bearing plate 3 is detachable and needs to be manually clamped in the position of the clamping block 504, after the gear 201 is limited by the pressing column 203 and the limiting hook 204, the moving belt 501 cannot engage with the rack on the gear 201, so that the gear 201 and the gear 201 are no longer engaged and driven, and the moving belt 501 no longer changes, and remains in a fixed state, which also ensures the position of the clamping block 504 and the bearing plate 3. Similarly, if the patient does not need to use a brace with high hardness, continue to drive the moving belt 501 through the rack on the gear 201 and the gear 201, so that the clamping block 504 gradually changes from the original initial position, that is, the inner side of the moving belt 501, to the outer side of the moving belt 501, and because the supporting block 502 is also fixed on the moving belt 501, the supporting block 502 will be synchronously driven and gradually displaced to the inner side of the moving belt 501, and the supporting block 502 is fixed with the elastic rope 4, in this state, the back of the patient directly contacts the elastic rope 4, and the brace conforms to the elastic effect, it is worth mentioning that when the clamping block 504 is located on the outer side of the moving belt 501, the clamping block 504 and the bearing plate 3 are detachably connected, and the bearing plate 3 can be selected according to the actual situation of the back of the patient, specifically, if the weight of the patient is greater than the bearing capacity of the elastic rope 4, the bending degree of the elastic rope 4 will be large, and the supporting capacity of the back will be reduced, if the bearing plate 3 is installed, the elastic rope 4 will abut against the bearing plate 3 under the continuous action, so as to further assist the supporting effect of the elastic rope 4, and improve the comfort of the whole thoracolumbar brace 1, and vice versa.

[0058] Finally, the position of the steel wire 6 is manually adjusted, so that the steel wire 6 and the bottom end of the thoracolumbar brace 1 are deformed, and because the steel wire 6 can be plastic, after manual deformation, the state after deformation can be ensured, manual adjustment around the weakening portion 601 can improve the adaptability of the bottom of the thoracolumbar brace 1 to the iliac bone position of the patient, and the fine adjustment of the steel wire 6 and the weakening portion 601 can change the strength according to the actual situation of the patient, which is beneficial to the wearing and recovery of the patient.
