Description

Technical Field

[0001] The utility model relates to medical care, in particular to an auxiliary scoliosis correction device. Background Art

[0002] Scoliosis is an elusive spinal deformity. There is no way to clearly define scoliosis. 80% of scoliosis cases are caused by unknown reasons. It can occur at any time from infancy to adolescence. In addition to affecting body shape, severe spinal deformation may also compress internal organs, affect fertility, and even endanger life.

[0003] A suitable scoliosis corrector can prevent the development of scoliosis, partially or completely correct scoliosis, and allow patients to avoid surgery. For patients with large scoliosis angles, relatively rigid scoliosis, or congenital scoliosis, treatment with a corrector can improve the preoperative flexibility of scoliosis, control the development of scoliosis, help choose the time of surgery, and improve the degree of surgical correction. The most common scoliosis corrector is a wearable brace.

[0004] When patients use wearable braces to assist in correction, they need to wear them for a long time. Most patients with scoliosis are teenagers, who are at the peak of their growth. Wearing braces for a long time can cause muscle atrophy and joint stiffness. Moreover, wearable correction braces are a one-time correction. For patients with severe scoliosis, wearing braces to directly restore their spine to a normal state is likely to cause discomfort to the patient. Utility Model Content

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] See also Figures 1 to 9 As an embodiment of the utility model, the scoliosis auxiliary correction device includes a bed frame 1 and a transmission block 10 symmetrically arranged on the bed frame 1, and a guide groove 101 is opened on the bed frame 1; the transmission block 10 is connected to a squeeze plate 14, and the transmission block 10 is also connected to a sliding mechanism arranged on the bed frame 1, and the sliding mechanism is used to drive the squeeze plate 14 to move closer to or away from each other on the guide groove 101 through the transmission block 10;

[0032] The bed frame 1 is provided with a driving mechanism, the driving mechanism is connected with a boss 5, and the driving mechanism drives the sliding mechanism to move through the boss 5;

[0033] The boss 5 is connected with a distance adjusting mechanism, which is arranged on the driving mechanism. When the driving mechanism is in operation, the distance adjusting mechanism can adjust the movement trajectory of the boss 5 to adjust the stroke of each reciprocating movement of the transmission block 10 through the sliding mechanism.

[0034] In this embodiment, when the patient lies flat on the bed frame 1, the driving mechanism starts to move, and drives the sliding mechanism to move by driving the boss 5 connected thereto. The sliding mechanism drives the squeezing plates 14 to move closer to or farther from each other on the guide groove 101 through the transmission block 10. When the squeezing plates 14 move closer to each other, the squeezing plates 14 squeeze the patient, so that the patient's bent spine gradually straightens with the movement of the squeezing plates 14. The stroke of the squeezing plates 14 approaching each other is the deformation of the spine. When the squeezing plates 14 move away from each other, the squeezing plates 14 gradually release the squeezing of the patient.

[0035] At the same time, when the drive mechanism is in motion, the distance adjustment mechanism changes the movement stroke of the transmission block 10 driven by the sliding mechanism by adjusting the movement trajectory of the boss 5, thereby changing the movement stroke of the extrusion plates 14. When the movement stroke of the extrusion plates 14 changes, the deformation of the spine will also change.

[0036] Thus, when the patient lies flat on the bed frame 1, the boss 5 is located on the minimum motion trajectory, and the amount of spinal deformation of the patient squeezed by the squeezing plate 14 is gradually increased by continuously increasing the motion trajectory of the boss 5. When the boss 5 reaches the maximum motion trajectory, the amount of spinal deformation of the patient squeezed by the squeezing plate 14 is gradually reduced by continuously reducing the motion trajectory of the boss 5. This process is gradual, which reduces the possibility of adverse reactions in patients during the correction process.

[0037] As a further solution of the utility model, the driving mechanism includes a motor 2 fixedly mounted on the bed frame 1, a transmission shaft 3 is fixedly connected to the output end of the motor 2, and a rotating plate 4 is fixedly connected to the end of the transmission shaft 3 away from the motor 2. The motor 2 drives the boss 5 to rotate through the rotating plate 4 to activate the sliding mechanism.

[0038] In this embodiment, when the motor 2 is working, it drives the transmission shaft 3 to rotate, thereby driving the rotating plate 4 to rotate along the axis of the transmission shaft 3, so that the boss 5 rotates with the rotation of the rotating plate 4. Driven by the boss 5, the sliding mechanism starts to move, thereby driving the squeezing plate 14 to squeeze the patient.

[0039] As a further solution of the utility model, the sliding mechanism includes two first sliding bars 8 fixedly mounted on the bed frame 1, and the two first sliding bars 8 are symmetrically arranged; a slide 7 is slidably mounted on each of the first sliding bars 8, and the two slides 7 are fixedly connected by a connecting rod 6; a notch 601 is opened on the connecting rod 6, and the notch 601 and the boss 5 are slidably matched with each other, and the boss 5 drives the slide 7 to reciprocate through the notch 601.

[0040] In this embodiment, when the boss 5 rotates with the rotating plate 4, the tangential force of the boss 5 will give a thrust to the inner wall of the notch 601, and this thrust will push the connecting rod 6 to move along the horizontal vertical guide groove 101. While pushing the connecting rod 6, the boss 5 will slide along the notch 601. Since the boss 5 is rotating, the notch 601 and the boss 5 cooperate to make the connecting rod 6 reciprocate along the horizontal vertical guide groove 101, thereby driving the slide 7 to slide reciprocally on the first slide bar 8 along the horizontal vertical guide groove 101.

[0041] The rotation diameter of the boss 5 along the transmission shaft 3 is the displacement stroke of the connecting rod 6 along the horizontal direction vertical guide groove 101.

[0042] As a further solution of the utility model, the sliding mechanism further includes a second sliding rod 18 fixedly mounted on the bed frame 1, the transmission block 10 is also symmetrically slidably arranged on the second sliding rod 18, and a second sliding block 1001 is fixedly mounted on the transmission block 10;

[0043] A slide plate 9 is fixedly mounted on the slide table 7 , and two second slide grooves 901 are provided on the slide plate 9 . The second sliding block 1001 is slidably engaged with the second slide grooves 901 . The two second slide grooves 901 are symmetrically arranged and inclined, and are in an "eight" shape.

[0044] In this embodiment, when the slide table 7 slides back and forth along the horizontal vertical guide groove 101 on the first slide bar 8, it will drive the slide plate 9 to reciprocate along the horizontal vertical guide groove 101. At this time, the second slide groove 901 is inclined so that the second slide groove 901 generates a force along the horizontal vertical guide groove 101 and a force along the horizontal parallel guide groove 101 on the second slider 1001. The force along the horizontal vertical guide groove 101 will cause the second slider 1001 to slide on the second slide groove 901; at the same time, the force along the horizontal parallel guide groove 101 will push the second slider 1001 to move along the horizontal parallel guide groove 101, thereby driving the transmission block 10 to slide along the horizontal parallel guide groove 101 on the second slide bar 18, so that the extrusion plate 14 can apply extrusion to the patient along the horizontal parallel guide groove 101.

[0045] The length of the projection of the sliding track of the second sliding block 1001 on the second sliding groove 901 on the guide groove 101 is the displacement distance of the extrusion plate 14 in the horizontal direction parallel to the guide groove 101 .

[0046] As a further solution of the present utility model, the transmission block 10 is connected to the extrusion plate 14 through a buffer mechanism, and the buffer mechanism includes a sleeve 11 fixedly mounted on the transmission block 10, and a sleeve column 12 is slidably mounted on the sleeve 11, and the sleeve column 12 and the sleeve 11 are mutually engaged. A spring 13 is arranged in the sleeve 11, and the two ends of the spring 13 are respectively in contact with the sleeve 11 and the sleeve column 12, and the sleeve column 12 is fixedly mounted on the extrusion plate 14.

[0047] In this embodiment, when the transmission block 10 slides along the horizontal direction parallel to the guide groove 101, the buffer mechanism drives the squeeze plate 14 to move along the horizontal direction parallel to the guide groove 101. When the squeeze plate 14 contacts the patient, the buffer mechanism starts to work, and the squeeze plate 14 pushes the sleeve 12 to slide in the sleeve 11 while compressing the spring 13 until the spring 13 cannot be compressed, thereby preventing the patient from being harmed during the correction treatment process.

[0048] As a further solution of the utility model, the pitch adjustment mechanism includes a first bevel gear 15 fixedly mounted on the bed frame 1, and the first bevel gear 15 is rotatably connected to the transmission shaft 3;

[0049] A screw rod 17 is rotatably mounted on the rotating plate 4 , and a second bevel gear 16 is fixedly mounted on one end of the screw rod 17 close to the first bevel gear 15 , and the first bevel gear 15 and the second bevel gear 16 are meshed with each other.

[0050] In this embodiment, when the rotating plate 4 rotates, the screw 17 is driven to rotate along the rotation center of the rotating plate 4, so that the second bevel gear 16 is also rotated along the rotation center of the rotating plate 4. The tangential force of this rotation causes the second bevel gear 16 to rotate along the axis of the screw 17 under the meshing action of the first bevel gear 15 and the second bevel gear 16, thereby driving the screw 17 to rotate along the axis of the screw 17 on the rotating plate 4.

[0051] As a further solution of the utility model, the distance adjustment mechanism also includes a first sliding groove 401 opened on the rotating plate 4, and a first slider 501 is slidably connected to the first sliding groove 401, and the first sliding groove 401 and the first slider 501 are slidably engaged with each other, and the boss 5 is fixedly installed on the first slider 501; an internal threaded sleeve 502 is also fixedly installed on the first slider 501, and the internal threaded sleeve 502 is threadedly connected to the screw rod 17.

[0052] In this embodiment, when the screw rod 17 rotates along its axis, the internal threaded sleeve 502 will be displaced on the screw rod 17 under the action of the thread, thereby driving the first slider 501 to slide on the first slide groove 401 to change the distance between the boss 5 and the transmission shaft 3, so that the rotation diameter of the boss 5 along the transmission shaft 3 is changed. This change causes the stroke of the connecting rod 6 to change, thereby changing the stroke of the extrusion plate 14 along the horizontal direction parallel to the guide groove 101, so as to change the extrusion force applied to the patient.

[0053] As a further solution of the utility model, the bed frame 1 is symmetrically provided with a bed board, the bed board is hinged to the bed frame 1, and the bed board is symmetrically provided with supporting legs, which are hinged to the bed board; a fixing block that interferes with the supporting legs is fixedly installed on the bed frame 1.

[0054] In this embodiment, when the fixed block on the bed frame 1 and the supporting legs are in mutual interference, the fixed block and the supporting legs can provide support for the bed board. When the correction is completed, the supporting force is released by releasing the mutual interference between the fixed block and the supporting legs, and the bed board and the bed frame 1, and the bed board and the supporting legs can be folded due to the hinged feature, thereby reducing the space occupied by the correction device.

[0055] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
