Description

Technical Field

[0001] The utility model relates to the field of scoliosis correction, in particular to a scoliosis correction head with variable correction direction and spinal correction equipment. Background Art

[0002] Scoliosis refers to the sideways curvature of one or more segments of the spine in the coronal plane, which deviates from the midline of the body, forming a curved spinal deformity. It is usually accompanied by rotation of the spine and increase or decrease of kyphosis or protrusion in the sagittal plane. There are also unequal heights of the ribs, rotational tilt of the pelvis, and abnormalities of the paravertebral ligaments and muscles.

[0003] Existing scoliosis correction devices are generally only able to apply force in a direction perpendicular to the patient, and the direction of force cannot be changed. Therefore, when correcting patients of different body shapes, the direction of force applied to the spine cannot be changed according to the patient's scoliosis condition and scoliosis position. As a result, the correction effect on the spine often fails to achieve the desired goal. For example, Chinese patent application number 202021586664.8: A lateral correction mechanism for treating scoliosis. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved. Utility Model Content

[0004] The purpose of the invention of the utility model is to overcome the defects described in the background technology, thereby realizing a scoliosis correction head and spinal correction equipment with variable correction direction. The device can realize multi-directional compression of the patient's body and can also adapt to patients of different body shapes, so that the direction of force applied to the spine can be changed according to the scoliosis of the patient's spine, and the spine can be better corrected.

[0005] To achieve the above-mentioned purpose of the invention, the technical solution of the present invention is: a scoliosis correction head with variable correction direction, comprising a mounting frame that can be fixedly mounted to a correction arm. A retractable support rod is provided at the end of the mounting frame, and an extrusion head that can rotate in multiple directions is provided on the support rod. This achieves multi-directional extrusion of the patient's body, while also allowing fine-tuning of the extrusion force, facilitating correction of the patient's spine. The extrusion head and the support rod are connected via a position conversion mechanism provided at the end of the support rod.

[0006] In the aforementioned scoliosis correction head with variable correction direction, the mounting frame is provided with multiple fixing holes for inserting bolts, facilitating installation of the extrusion head. The mounting frame is connected to the support rod via an electric push rod fixed to the mounting frame, enabling fine-tuning of the applied pressure to avoid excessive extrusion force.

[0007] In the above-mentioned scoliosis correction head with variable correction direction, the support rod is placed horizontally. A limit frame is fixedly provided at the top end of the support rod. Support rods are fixedly provided on both sides of the support rod. A vertical rod is fixedly provided on the support rod at the front end of the limit frame.

[0008] In the above-mentioned scoliosis correction head with variable correction direction, the limit frame is C-shaped, the support rod is arc-shaped with its end facing upward, and the vertical rod is inverted L-shaped with its end facing the extrusion head.

[0009] In the aforementioned scoliosis correction head with variable correction direction, the extrusion head is hollow. A soft cloth is fixed to the front end of the extrusion head for contact with the patient's body, preventing direct contact between the internal structure and the patient's body, which could cause physical pain. A shielding cloth is also installed at the rear end of the extrusion head to conceal the internal structure, making the correction head more aesthetically pleasing and alleviating patients' fear of using the device.

[0010] In the above-mentioned scoliosis correction head with variable correction direction, the position conversion mechanism includes a semicircular rod horizontally hinged at the rear end of the extrusion head. The semicircular rod is located between the openings of the limit frame, and its bottom ends abut the top of the support rod. An arc-shaped rack is fixedly installed on the outer side of the semicircular rod in the direction of the limit frame. A gear meshing with the arc-shaped rack is vertically installed in the opening of the limit frame. A first bidirectional motor that drives the gear is fixedly installed at the top of the limit frame. This enables the extrusion head to swing left and right, thereby changing the left and right direction of the force applied to the patient's spine.

[0011] In the aforementioned scoliosis correction head with variable correction direction, the position conversion mechanism also includes a worm gear mounted vertically on a support rod below the end of the vertical rod. A second bidirectional motor driving the worm gear is fixed to the top of the vertical rod. A worm gear meshing with the worm gear is fixed vertically to the middle rear end of the extrusion head. This allows the extrusion head to swing up and down, thereby changing the direction of force applied to the patient's spine.

[0012] In the aforementioned scoliosis correction head with a variable correction direction, the end of the extrusion head is provided with an extrusion mechanism capable of applying pressure to the patient's body. The extrusion mechanism comprises two sets of brackets arranged vertically and arranged horizontally and rotatably within the front end of the extrusion head.

The fixing rod is located at the ends of the triangular plates, and the brackets are rotatably arranged with the extrusion head through the middle of the triangular plates. Rollers are provided horizontally and rotatably at both ends between the triangular plates located in the direction of the extrusion head opening, enabling compression of the patient's body.

[0013] In the above-mentioned scoliosis correction head with variable correction direction, the extrusion mechanism also includes a control plate vertically arranged inside the extrusion head and slidable in the vertical direction. Grooved rings are fixedly arranged at the upper and lower ends of the control plate, and the grooved rings are arranged in the horizontal direction. The fixed rods are slidably arranged in the corresponding grooved rings respectively. A guide rod is vertically fixedly arranged inside the extrusion head on the rear side of the control plate, and the guide rod is slidably connected to the control plate. A lead screw is vertically rotated inside the extrusion head on the rear side of the control plate, and the lead screw is threadedly connected to the control plate. A third bidirectional motor that drives the lead screw to rotate is fixedly arranged at the end of the extrusion head. It can change the pressure point on the patient's body to avoid squeezing one position for a long time, which may cause pain at the contact point between the patient's body and the correction head.

[0014] The present invention also discloses a ring saw, comprising a correction bed, a correction arm and a correction head, wherein the correction arm is detachably arranged on the correction bed, and the correction head is detachably arranged at the end of the correction arm, and the correction head is the above-mentioned scoliosis correction head with variable correction direction.

[0028] The following is a more detailed description of the scoliosis correction head with variable correction direction and the spinal correction device of the present invention with reference to the accompanying drawings and through specific implementation methods.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0030] See also Figures 1-4The scoliosis correction head with variable correction direction in this embodiment can achieve multi-directional compression on the patient's body, and can also adapt to patients of different body shapes, so that the direction of force applied to the spine can be changed according to the scoliosis of the patient's spine, and the spine can be corrected better. In this embodiment, it mainly includes a mounting frame 1 that can be fixed to the correction arm. The mounting frame 1 is provided with a plurality of fixing holes 5 for inserting bolts, and the correction head is mounted on the correction arm by bolts. A retractable support rod 2 is provided at the end of the mounting frame 1, and the mounting frame 1 and the support rod 2 are connected by an electric push rod 6 fixedly provided on the mounting frame 1. By controlling the extension and retraction of the electric push rod 6, the pressure applied to the spine can be fine-tuned so that the force applied to the spine will not be too large, causing additional pain and damage to the patient.

[0031] The support rod 2 is provided with an extrusion head 3 that can rotate in multiple directions. The extrusion head 3 that can rotate in multiple directions can achieve multi-directional extrusion of the patient's body, which is convenient for correcting the patient's spine. The extrusion head 3 is a hollow structure. The front end of the extrusion head 3 is fixedly provided with a soft cloth 10 that contacts the patient's body. The soft contact with the patient's body prevents the internal structure from directly contacting the patient's body and causing physical pain. The rear end of the extrusion head 3 is provided with a shielding cloth 11, which can cover the internal structure, making the correction head more beautiful, and at the same time avoiding the patient's fear of using the equipment for correction.

[0032] In order to change the direction of force applied to the correction head. Figure 2 and Figure 3 In this embodiment, the support rod 2 is in a horizontal position. A structure for guiding the support rod 2 can be provided on the mounting frame 1 to prevent the support rod 2 from rotating around the electric push rod 6. A limiting frame 7 is fixedly provided at the top of the support rod 2. Support rods 8 are fixedly provided on both sides of the support rod 2. A vertical rod 9 is vertically fixed on the support rod 2 at the front end of the limiting frame 7. The limiting frame 7 is a C-shaped structure, the support rod 8 is an arc-shaped structure with its end facing upward, and the vertical rod 9 is an inverted L-shaped structure with its end facing the direction of the extrusion head 3.

[0033] The extrusion head 3 and the support rod 2 are connected via a position conversion mechanism 4 provided at the end of the support rod 2. The position conversion mechanism 4 includes a semicircular rod 41 horizontally hinged at the rear end of the extrusion head 3. The semicircular rod 41 is located between the openings of the limiting frame 7 and the bottoms of both ends are in contact with the top of the support rod 8. An arc-shaped rack 42 is fixedly provided on the outside of the semicircular rod 41 in the direction of the limiting frame 7. A gear 43 meshing with the arc-shaped rack 42 is vertically provided at the opening of the limiting frame 7. A first bidirectional motor 44 that drives the gear 43 to rotate is fixed at the top of the limiting frame 7. The first bidirectional motor 44 is controlled to work, thereby driving the arc-shaped rack 42 to rotate through the gear 43. At this time, the semicircular rod 41 drives the extrusion head 3 to swing left and right.

[0034] The position conversion mechanism 4 also includes a worm 45 vertically rotatably arranged on the support rod 2 below the end of the vertical rod 9, and a second bidirectional motor 46 is fixedly arranged on the top of the vertical rod 9 to drive the worm 45 to rotate. A worm gear 47 meshing with the worm 45 is vertically fixedly arranged at the middle of the rear end of the extrusion head 3. The second bidirectional motor 46 is controlled to work, thereby driving the worm gear 47 to rotate through the worm 45, and at this time, the worm gear 47 drives the extrusion head 3 to swing up and down. In this way, multi-directional extrusion of the patient's body is achieved, and it can also adapt to patients of different body shapes, so that the direction of force applied to the spine can be changed according to the scoliosis of the patient's spine, which can better correct the spine.

[0035] To achieve changes in the pressure points on the patient's body. Figure 2-Figure 4 The end of the extrusion head 3 is provided with an extrusion mechanism 12 that can apply pressure to the patient's body. The extrusion mechanism 12 includes two sets of brackets 121 arranged vertically and arranged horizontally and rotatably inside the front end of the extrusion head 3. The brackets 121 include a horizontally arranged fixed rod 1211 and a triangular plate 1212 fixedly provided at both ends of the fixed rod 1211. The fixed rod 1211 is located at the ends of the triangular plate 1212. The bracket 121 is rotatably provided with the extrusion head 3 through the middle of the triangular plate 1212. Rollers 1213 are rotatably provided at both ends between the triangular plates 1212 located in the direction of the opening of the extrusion head 3.

[0036] The extrusion mechanism 12 also includes a control plate 122 vertically arranged inside the extrusion head 3 and slidable in the vertical direction. Grooved rings 123 are fixedly arranged at the upper and lower ends of the control plate 122, and the grooved rings 123 are arranged in the horizontal direction. The fixed rods 1211 are slidably arranged in the corresponding grooved rings 123. A guide rod 124 is vertically fixedly arranged inside the extrusion head 3 on the rear side of the control plate 122, and the guide rod 124 is slidably connected to the control plate 122. A lead screw 125 is vertically rotatably arranged inside the extrusion head 3 on the rear side of the control plate 122, and the lead screw 125 is threadedly connected to the control plate 122. A third bidirectional motor 126 is fixedly arranged at the end of the extrusion head 3 to drive the lead screw 125 to rotate. When the correction time is long, the third bidirectional motor 126 is controlled to operate, thereby driving the control plate 122 up and down via the lead screw 125. This in turn controls the triangular plate 1212 to rotate about its center, causing the roller rod 1213 to alternately contact the patient's body. At this time, the upper and lower fixed rods 1211 slide within the groove ring 123. This changes the pressure point on the patient's body, avoiding prolonged compression at one location, which can cause pain at the contact point between the patient's body and the correction head.

[0037] The present invention also discloses a ring saw, comprising a correction bed, a correction arm and a correction head, wherein the correction arm is detachably arranged on the correction bed, and the correction head is detachably arranged at the end of the correction arm, and the correction head is the above-mentioned scoliosis correction head with variable correction direction.

[0038] The present invention provides a method for using a scoliosis correction head and spinal correction device with variable correction direction. First, the correction head is mounted on the correction arm using bolts. Before correcting the patient, the first bidirectional motor 44 is controlled to operate, thereby driving the arc-shaped rack 42 to rotate via the gear 43. The semicircular rod 41 then drives the extrusion head 3 to swing left and right. During this process, the semicircular rod 41 is limited in its vertical direction by the limit frame 7 and the support rod 8. The second bidirectional motor 46 is controlled to operate, thereby driving the worm gear 47 to rotate via the worm 45. The worm gear 47 then drives the extrusion head 3 to swing up and down. This achieves multi-directional compression of the patient's body and can accommodate patients of different body types. The direction of force applied to the spine can be changed according to the patient's scoliosis condition, thereby better correcting the spine. When correcting the patient, the correction head is controlled to move so that the soft cloth 10 contacts the patient's body, preventing the internal structure from directly contacting the patient's body and causing physical pain. When the patient's spine is squeezed to a certain position, the pressure on the spine can be fine-tuned by controlling the extension and contraction of the electric push rod 6, so that the force applied to the spine will not be too large, causing additional pain and damage to the patient.

[0039] When the correction time is prolonged, the third bidirectional motor 126 is activated, driving the control plate 122 up and down via the lead screw 125. This in turn controls the triangular plate 1212 to rotate about its center, causing the roller rods 1213 to alternately contact the patient's body. At this point, the upper and lower fixed rods 1211 slide within the grooved ring 123. This changes the point of pressure on the patient's body, avoiding prolonged pressure on a single location, which can cause pain at the point of contact between the patient's body and the correction head. During this process, the guide rods 124 guide the control plate 122.
