Description

Technical Field

[0001] The present invention relates to the technical field of thoracolumbar braces, and particularly to a segmented thoracolumbar postoperative brace with adjustable hardness. Background Art

[0002] Thoracolumbar braces are special medical auxiliary devices, mainly used in the rehabilitation process after thoracic vertebra fractures or thoracic surgeries. Their functions mainly include protection, fixation, and correction, etc., helping to limit thoracic activities, avoid excessive stress on the fracture site, and promote the recovery of diseases.

[0003] Currently, after thoracolumbar surgeries, it is necessary to stabilize the surgical site of the patient, and thoracolumbar braces can provide good protection and stability. Thoracolumbar braces are often divided into dorsal braces and ventral braces. First, let the postoperative patient lie on their side, attach the dorsal brace to the patient's back, and then slightly move the brace to make it fit the patient's back as tightly as possible. Then, turn the patient over and wear the ventral brace. After wearing and fixing, use Velcro to fix the two parts of the brace.

[0004] However, currently commercially available thoracolumbar braces on the market are all for independent lumbar vertebrae or thoracic vertebrae, and they all have a fixed strength. For long-segment fixed thoracolumbar braces, customizing at the hospital is the best method, but more attention is paid to the adaptability of patients. For the strength, it remains the same. Different patients have different spinal segments, and the required fixation strength during surgery is also different. Sometimes strong fixation is needed, and sometimes elastic fixation is needed. However, the existing braces cannot change the strength, so when in use, the braces cannot be well adapted to the actual situation, affecting the use of patients during or after surgery. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a segmented thoracolumbar postoperative brace with adjustable hardness to solve the problem that different patients have different spinal segments, and the required fixation strength during surgery is also different. Sometimes strong fixation is needed, and sometimes elastic fixation is needed. However, the existing braces cannot change the strength, so when in use, the braces cannot be well adapted to the actual situation, affecting the use of patients during or after surgery.

[0006] To solve the above technical problem, the present invention provides the following technical solutions:

[0007] A segmented thoracolumbar postoperative brace with adjustable hardness, including a thoracolumbar brace. A connecting column is installed at the middle position of the thoracolumbar brace. A bearing plate is attached to the middle opening of the thoracolumbar brace. An elastic rope is attached to the surface of the bearing plate. Connecting plates are fixedly connected to both sides of the middle opening of the thoracolumbar brace. A steel wire is installed at the bottom of the thoracolumbar brace. A reinforcing plate is snap-fitted into the inner cavity of the thoracolumbar brace;

[0008] An auxiliary adjustment component, which is used to change the strength of the thoracolumbar brace, and the auxiliary adjustment component is connected to the thoracolumbar brace.

[0009] Optionally, the auxiliary adjustment component includes gears arranged on both sides of the opening in the middle of the thoracolumbar brace. An extension column is fixedly connected to the end of the gear away from the middle of the thoracolumbar brace. A pressing column is slidably connected to the extension column. A limiting hook is fixedly connected to the surface of the pressing column. A convex portion is provided at the bottom of the limiting hook close to the outer surface of the gear.

[0010] Optionally, a moving belt is attached to the surface of the connecting plate. Support blocks are evenly attached to one side of the connecting plate along the length direction of the connecting plate. A limiting plate is fixedly connected to one side of the connecting plate and is perpendicular to the surface of the connecting plate. A clamping block is fixedly connected to the outer surface of one side of the moving belt. Tooth tracks are fixedly connected to both sides of the moving belt.

[0011] Optionally, weakening portions are provided on the surface of the steel wire, and there are several weakening portions.

[0012] Optionally, one end of the gear is a convex column and the other end is a groove. The extension column is fixed in the middle of the groove of the gear. The size of the slot formed in the inner cavity of the pressing column is the same as that of the extension column.

[0013] Optionally, one end of the limiting hook is fixedly connected to the surface of the pressing column, the other end of the limiting hook is open, and its bottom is attached to the surface of the gear. The limiting hook is arranged around the circumference of the pressing column. The convex portion is provided on the surface of the middle of the limiting hook and is attached to the surface of the gear.

[0014] Optionally, the side surface of the moving belt is attached to the side surface of the connecting plate. The support block is L-shaped, and its end is fixedly connected to the outer surface of the moving belt.

[0015] Optionally, the clamping block is made of U-shaped plastic and is hollow in the middle. 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 portions are provided in the middle of the steel wire and at positions extending outward from the middle.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above scheme, the overall adaptability of the thoracolumbar brace to the patient can be improved through the auxiliary adjustment component. When wearing, the overall strength of the thoracolumbar brace can be changed according to the different usage environments and personal conditions of the patients. Since the sizes of the ilium of the patients are also different, the position of the reinforcement plate can be just clamped and stabilized by adjusting the steel wire, so that the patient can be more flexible when wearing it, which improves the overall adaptability and flexibility of the thoracolumbar brace, and can also improve the ability to adjust the strength of the middle part of the thoracolumbar brace, so that when in use, the brace can be well adapted to ensure that the patient can use it during or after surgery.

[0020] By setting up gears, extension columns, pressing columns and limiting hooks, the gears can complete self-rotation. The ability to self-rotate relies on the raised column between the gear and the connecting plate. The raised column is a component on the gear. When the gear rotates, the pressing column and the limiting hook are away from the positions of the gear and the extension column, so that the gear has no obstacles and can complete autonomous rotation, thereby ensuring the flexibility of gear use, which can be changed according to actual conditions, thereby improving the convenience of user adjustment.

[0021] By setting a moving belt, a supporting block, a limiting plate and a clamping block, in the initial state, the moving belt is attached to the surface of the connecting plate and the limiting plate. By manually grasping any position of the outer surface of the moving belt and starting to pull it downward or lift it upward, the teeth inside the moving belt and the rack on the gear begin to mesh and transmit. The brace in this state is suitable for patients who require hardness. The bearing plate is directly clamped at the position of the clamping block. At this time, after the gear is limited by the pressing column and the limiting hook, the moving belt cannot mesh with the rack on the gear, thereby failing to drive the moving belt transmission, ensuring that the position of the clamping block is stable, thereby further assisting the supporting effect of the elastic rope and improving the overall wearing comfort of the thoracolumbar brace.

[0045] As Figures 1 to 14As shown in the figure, an embodiment of the present invention provides a segmented thoracolumbar postoperative brace with adjustable hardness, which includes a thoracolumbar brace 1 and an auxiliary adjustment component. A connecting column 2 is installed at 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 plates 5 are symmetrically arranged on both sides of the bearing plate 3, that is, the connecting plates 5 are 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. A reinforcing plate 7 is snap-fitted into the inner cavity of the thoracolumbar brace 1.

[0046] The auxiliary adjustment component is used to change the strength of the thoracolumbar brace 1. The auxiliary adjustment component is connected to 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 as a whole. One part is the dorsal brace, and the other part is the ventral brace. The middle part of the whole thoracolumbar brace 1 is the opening part, and the inner cavity at the bottom end of the thoracolumbar brace 1 is grooved, with the ability of slight deformation. Slots are opened at both ends of the bearing plate 3. The connecting plate 5 is made of plastic and is fixedly connected to the opening position in the middle of the thoracolumbar brace 1, which will not be elaborated here. The connecting plate 5 and the bearing plate 3 are 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 through the inner cavity of the connecting plate 5. The steel wire 6 is made of metal and is fixedly connected to the bottom of the thoracolumbar brace 1. The overall shape of the steel wire 6 is the same as 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. It is snap-fitted into the inner cavity of the thoracolumbar brace 1, and the reinforcing plate 7 is restricted in the inner cavity of the thoracolumbar brace 1 by the steel wire 6.

[0047] In the above structure, when in use, the patient lies face up on the bed first, and then the patient's body is turned over so that the patient leans to one side, turns over to the left side, and the dorsal brace is first worn on the patient's back, and then the patient lies flat normally. Start wearing the ventral brace. When wearing it, it can be determined whether to improve the stability according to the actual size of the patient's chest and waist. When in use, the fitting effect between the position of the patient's chest and waist and the thoracolumbar brace 1 is different by changing the position between the bearing plate 3 and the elastic cord 4. Moreover, the sizes of the patient's iliac bone parts are also different. By changing the actual position of the steel wire 6, the bottom of the thoracolumbar brace 1 can be bent. At the same time, the reinforcing plate 7 is integrally clamped into the inner cavity at the bottom end of the thoracolumbar brace 1 from bottom to top, and the stability effect of the reinforcing plate 7 is enhanced in cooperation with the steel wire 6. Through the auxiliary adjustment component, the overall adaptability of the thoracolumbar brace 1 to the patient can be further improved. When wearing, the overall strength of the thoracolumbar brace 1 can be changed according to the different use environments and the patient's own conditions of the patient. Moreover, due to the different iliac bone sizes of the patient, the position of the reinforcing plate 7 can be just clamped and stabilized by adjusting the steel wire 6, so that the patient can be more flexible when wearing, improving the overall adaptability and flexibility of the thoracolumbar brace 1, and also improving the ability to adjust the strength in the middle part of the thoracolumbar brace 1. Thus, when in use, the brace can be well adapted to ensure the use of the patient during or after the operation.

[0048] As Figures 10 to 11 shown, the auxiliary adjustment component includes a gear 201 attached to the opening in the middle of the thoracolumbar brace 1. The end of the gear 201 away from the middle of the thoracolumbar brace 1 is fixedly connected with an extension column 202. A pressing column 203 is slidably connected to the inner cavity of the extension column 202. A limiting hook 204 is fixedly connected to the surface of the pressing column 203. The limiting hook 204 is arranged around the circumference of the pressing column 203. A convex portion 205 is opened at the bottom end of the limiting hook 204 close to the outer surface of the gear 201. One end of the gear 201 is a convex column, the other end is a groove, and the surface is a rack. The convex column is rotatably connected to the surface of the connecting plate 5 (as Figure 9 ), the extension column 202 is fixedly connected to the center position of the groove of the gear 201 and extends a certain distance. The pressing column 203 is slidably connected in the groove and the pressing column 203 is slidably connected to the outer surface of the extension column 202. A slot is opened in the middle of the pressing column 203, and the size of the slot is the same as that of the extension column 202. 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 is fixedly connected to the surface of the pressing column 203 away from the extension column 202, and the other end is open and fits against the outer surface of the gear 201. The convex portion 205 is opened at the bottom end of the open end of the limiting hook 204 and fits against the outer surface of the gear 201.

[0050] In the above structure, the gear 201 can rotate on its own. Its ability to rotate on its own depends on the protruding column between the gear 201 and the connecting plate 5. This protruding column is on the gear 201. When the gear 201 rotates, the positions of the pressing column 203 and the limiting hook 204 move away from the extending column 202. It can be observed through Figure 11 that when the gear 201 rotates, the pressing column 203 and the limiting hook 204 move away from the positions of the gear 201 and the extending column 202, so that there is no obstacle on the gear 201 and it can complete autonomous rotation. When it is necessary to stop the rotation of the gear 201 for limiting, press the pressing column 203 to make the extending column 202 snap into the slot hole. At this time, the extending column 202 completely enters the slot hole. Push the pressing column 203 forcefully, and then the limiting hook 204 will start to slide on the outer surface of the gear 201 and gradually approach the rack fixed on the outer surface of the gear 201, and make the open end of the limiting hook 204 fit with the gap between the racks of the gear 201, that is, the open end of a limiting hook 204 is inserted between two adjacent racks, so that the rack of the gear 201 cannot be matched with other parts and cannot rotate normally, thus completing 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 operating normally, the pressing column 203 and the limiting hook 204 are not snapped on the side of the gear 201. When it is necessary to limit the gear 201, just snap the pressing column 203 and the limiting hook 204 onto the gear 201. The above process can ensure the flexibility of the use of the gear 201, which can be changed according to the actual situation, improving the convenience of adjustment for the user.

[0051] Such as Figures 6 to 9As shown, the surface of the connecting plate 5 is attached to a moving belt 501, one side of the connecting plate 5 is evenly attached to a supporting block 502 along the length direction of the connecting plate 5, one side of the connecting plate 5 is fixedly connected to a limiting plate 503, and the limiting plate 503 is perpendicular to the surface of the connecting plate 5, the outer surface of the moving belt 501 is fixedly connected to a clamping block 504, and both sides of the moving belt 501 are fixedly connected to gearways 505. The moving belt 501 is made of plastic, and one side thereof is attached to the surface of the connecting plate 5, and has a certain friction force. The end of the supporting block 502 is fixedly connected to the side of the moving belt 501, and is in an L-shaped shape, and the supporting block 502 is close to the moving belt 501. The side of the belt 501 surface is designed with thorns, which can firmly fix the elastic rope 4. The limit plate 503 is fixedly connected to the surface of the connecting plate 5. The limit plate 503 is distributed in a stepped manner. The inner part fixed to the connecting plate 5 is smaller than the inner circle of the moving belt 501, and the outer part attached to the outer surface of the moving belt 501 is larger than the outer circle of the moving belt 501. The reason why the moving belt 501 does not fall is that the outer part of the limit plate 503 is attached to the outer surface of the moving belt 501. The limit plate 503 prevents the moving belt 501 from tilting and falling. The limit plate 503 plays a blocking role but does not hold the moving belt 501. The clamping block 504 is made of plastic and is U-shaped. A slot is provided in the middle of the clamping block 504. Clamping slots are provided at both ends of the supporting plate 3. The size of the clamping slots is consistent with the size of the clamping block 504. When in use, the two ends of the supporting plate 3 are directly clamped in the clamping block 504 to fix the position of the supporting plate 3. The tooth path 505 is fixedly connected to the inner surface of the moving belt 501 and is distributed in a curved array on the inner surface of the moving belt 501, and is adapted to the 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 connecting plate 5 and the limiting plate 503. By manually grasping any position of the outer surface of the moving belt 501 and starting to pull it downward or lift it upward, the tooth track 505 inside the moving belt 501 and the rack on the gear 201 begin to mesh and transmit, and then the supporting block 502 and the clamping block 504 on the moving belt 501 begin to change their positions and move synchronously with the changes of the moving belt 501, such as Figure 2 The middle bearing plate 3 is located on the inner side of the elastic rope 4. The brace in this state is suitable for patients who require hardness, and is also the initial state of the brace. Figure 9Define the left side of the moving belt 501 as the inner surface and the right side of the moving belt 501 as the outer surface. That is, in the initial state, it is adapted to patients with a certain requirement for the hardness of the brace. At this time, the bearing plate 3 is located on the inner surface of the moving belt 501, and the support block 502 is located on the outer surface of the moving belt 501. Among them, the bearing plate 3 is detachable and needs to be manually clamped at the position of the clamping block 504 for fixation. After the gear 201 is limited by the pressing column 203 and the limiting hook 204, the moving belt 501 can no longer mesh with the rack on the gear 201. As a result, the tooth track 505 and the gear 201 no longer mesh and drive, and further the moving belt 501 no longer changes and remains in a fixed state, which also ensures the fixed positions of the clamping block 504 and the bearing plate 3. Similarly, if the patient does not need to use a brace with a high hardness, continue to drive the moving belt 501 to change through the meshing and transmission of the tooth track 505 and the rack on the gear 201. As a result, the clamping block 504 gradually changes from the original initial position, that is, the inner surface of the moving belt 501, and moves along with the moving belt 501 to the outer surface of the moving belt 501. Since the support block 502 is also fixed on the moving belt 501, the support block 502 will be synchronously driven to gradually be located on the inner surface of the moving belt 501. And the elastic cord 4 is fixed on the support block 502. In this state, the patient's back will directly contact the elastic cord 4, and the brace conforms to the elastic effect. It is worth mentioning that when the clamping block 504 is on the outer surface of the moving belt 501, the clamping block 504 and the bearing plate 3 are in a detachable relationship, and the bearing plate 3 can be disassembled and assembled according to the actual situation of the patient's back. Specifically, if the weight of the patient is greater than the bearing capacity of the elastic cord 4, the bending degree of the elastic cord 4 will be very large, and the supporting ability for the back will decrease. If the bearing plate 3 is installed, the elastic cord 4 will abut against the bearing plate 3 under continuous action, so as to further assist the supporting effect of the elastic cord 4 and improve the comfort of the overall wearing of the thoracolumbar brace 1. Otherwise, it can be removed.

[0053] As Figures 12 to 14 shown, a weakening portion 601 is provided on the surface of the steel wire 6. There are several weakening portions 601. The shape of the steel wire 6 is adapted to 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 ends of the thoracolumbar brace 1. The bottom end has a certain deformation ability. The weakening portion 601 is provided on the surface of the steel wire 6 and is unevenly distributed. In the above structure, by manually adjusting the position of the steel wire 6, both the steel wire 6 and the bottom end of the thoracolumbar brace 1 will undergo a certain deformation. Since the steel wire 6 can be plastic, after manual deformation, the deformed state can be ensured. By manually adjusting around the weakening portion 601, the adaptability of the bottom of the thoracolumbar brace 1 to the iliac position of the patient can be improved, and with the fine adjustment of the steel wire 6 and the weakening portion 601, the strength can be changed according to the actual situation of the patient, which is beneficial to the patient's wearing and recovery.

[0054] The working process of the technical solution provided by the present invention is as follows:

[0055] During use, the patient lies flat on the bed first, and then the patient's body is turned over so that the patient inclines to one side, turns over to the left side, and the dorsal brace is first worn on the patient's back, and then the patient lies flat normally. Start wearing the ventral brace. When wearing it, it can be determined whether to improve the stability according to the actual size of the patient's chest and waist. During use, by changing the position between the bearing plate 3 and the elastic cord 4, the fitting effect between the patient's chest and waist position and the thoracolumbar brace 1 is different, and the iliac bone part sizes of the patients are also different. By changing the actual position of the steel wire 6, the bottom of the thoracolumbar brace 1 can be bent. At the same time, the reinforcing plate 7 is integrally clamped into the inner cavity at the bottom end of the thoracolumbar brace 1 from bottom to top, and the steel wire 6 is used to cooperate to enhance the stability effect of the reinforcing plate 7. Through the auxiliary adjustment component, 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 environments and the patient's own conditions. Since the iliac bone sizes of the patients are also different, by adjusting the steel wire 6, the position of the reinforcing plate 7 can be just clamped and stabilized, so that the patient can be more flexible when wearing, improving the overall adaptability and flexibility of the thoracolumbar brace 1, and also improving the ability to adjust the strength of the middle part of the thoracolumbar brace 1. Therefore, during use, the brace can be well adapted to ensure the use of the patient during or after the operation.

[0056] The gear 201 can complete self-rotation. The ability to rotate is dependent on the protruding column between the gear 201 and the connecting plate 5. This protruding column is on the gear 201. When the gear 201 rotates, the positions of the pressing column 203 and the limiting hook 204 are far from the extending column 202, and it can be passed through Figure 11It is observed that when the gear 201 rotates, the pressing post 203 and the limiting hook 204 move away from the gear 201 and the extension post 202, so that there is no obstacle for the gear 201 and it can complete autonomous rotation. When it is necessary to stop the rotation of the gear 201 for limiting, the pressing post 203 is pressed to make the extension post 202 snap into the slot hole. At this time, the extension post 202 completely enters the slot hole, and the pressing post 203 is pushed forcefully. As a result, the limiting hook 204 will start to slide on the outer surface of the gear 201 and gradually approach the rack fixed on the outer surface of the gear 201, and the open end of the limiting hook 204 is adapted to the gap between the racks of the gear 201, that is, the open end of one limiting hook 204 is inserted between two adjacent racks, so that the rack of the gear 201 cannot be adapted to other parts and cannot rotate normally, thus achieving the limiting effect. It is worth mentioning that the pressing post 203 and the limiting hook 204 can be removed. That is, when the gear 201 is operating normally, the pressing post 203 and the limiting hook 204 are not clamped on the side of the gear 201. When it is necessary to limit the gear 201, the pressing post 203 and the limiting hook 204 can be clamped to the gear 201. The above process can ensure the flexibility of the use 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 surfaces of the connecting plate 5 and the limiting plate 503. By manually grasping any position on the outer surface of the moving belt 501 and starting to pull it down or lift it up, the tooth track 505 inside the moving belt 501 and the rack on the gear 201 start to mesh and drive, and then the support block 502 and the clamping block 504 on the moving belt 501 start to change their positions and move synchronously with the change of the moving belt 501, as Figure 2 The bearing plate 3 is located inside the elastic rope 4. In this state, the brace is suitable for patients with requirements for hardness, and it is also the initial state of the brace. According to Figure 9Define the left side of the moving belt 501 as the inner surface and the right side of the moving belt 501 as the outer surface. That is, in the initial state, it is adapted to patients with a certain requirement for the hardness of the brace. At this time, the bearing plate 3 is on the inner surface of the moving belt 501, and the support block 502 is on the outer surface of the moving belt 501. Among them, the bearing plate 3 is detachable and needs to be manually snapped into the position of the snap block 504 for fixation. After the gear 201 is limited by the pressing column 203 and the limiting hook 204, the moving belt 501 cannot mesh with the rack on the gear 201. Thus, the tooth track 505 and the gear 201 no longer mesh and drive, and further the moving belt 501 no longer changes and remains in a fixed state, which also ensures the fixed positions of the snap block 504 and the bearing plate 3. Similarly, if the patient does not need to use a brace with a higher hardness, the moving belt 501 is changed by the transmission of the tooth track 505 and the rack on the gear 201. As a result, the snap block 504 gradually changes from the original initial position, that is, the inner surface of the moving belt 501, to the outer surface along with the moving belt 501. Since the support block 502 is also fixed on the moving belt 501, the support block 502 will be synchronously driven to gradually displace to the inner surface of the moving belt 501. And the elastic cord 4 is fixed on the support block 502. In this state, the patient's back will directly contact the elastic cord 4, and the brace meets the elastic effect. It is worth mentioning that when the snap block 504 is on the outer surface of the moving belt 501, the snap block 504 and the bearing plate 3 are in a detachable relationship, and the bearing plate 3 can be disassembled and assembled according to the actual situation of the patient's back. Specifically, if the weight of the patient is greater than the bearing capacity of the elastic cord 4, the bending degree of the elastic cord 4 will be very large, and the supporting ability for the back will decrease. If the bearing plate 3 is installed, the elastic cord 4 will abut against the bearing plate 3 under continuous action, so as to further assist the supporting effect of the elastic cord 4 and improve the comfort of the overall wearing of the thoracolumbar brace 1. Conversely, it can be removed.

[0058] Finally, by manually adjusting the position of the steel wire 6, the steel wire 6 and the bottom end of the thoracolumbar brace 1 both undergo a certain deformation. Since the steel wire 6 can be plastically deformed, after manual deformation, the deformed state can be ensured. By manually adjusting around the vicinity of the weakening part 601, the adaptability of the bottom of the thoracolumbar brace 1 to the iliac position of the patient can be improved. And with the fine adjustment of the steel wire 6 and the weakening part 601, the strength can be changed according to the actual situation of the patient, which is beneficial to the patient's wearing and recovery.
