Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a spinal correction device. Background Technology

[0002] The spine is a structure composed of multiple bones along the center of the human back, called vertebrae. From top to bottom, the spine includes the cervical, thoracic, lumbar, sacral, and coccygeal vertebrae. These vertebrae are interconnected by ligaments, muscles, and joints, forming a continuous, flexible, and strong support structure. The spine not only supports the weight of the body but also protects the spinal cord and nerve roots; these important neural structures are responsible for transmitting signals between the brain and other parts of the body.

[0003] According to patent document CN113069262A, a spinal correction device is disclosed, relating to the field of back correction. It includes a chair with a drive mechanism on the back of the chair back. The drive mechanism is connected to a back-pushing mechanism and a stretching mechanism, and the stretching mechanism is connected to a shoulder fixing strap. When a patient sits on the chair, the shoulder fixing strap secures the patient's shoulders. The drive mechanism drives the back-pushing and stretching mechanisms. The back-pushing mechanism pushes the patient's back forward, while the stretching mechanism pulls the patient's shoulders backward, thereby correcting the patient's back. This method has a good corrective effect, and the correction process can be adjusted appropriately according to the patient's actual situation to reduce discomfort during the correction process.

[0004] With societal development, the pressure from work and study is becoming increasingly heavy. People often find themselves in a state of spinal curvature during work and study, leading to varying degrees of changes in the shoulders and spine. This is especially true for primary and secondary school students, who frequently hunch their heads while writing or reading. Over time, this can result in hunchback, sunken chest, and collapsed shoulders. Hunchback not only damages physical appearance but also causes inconvenience in daily life. If not corrected in time, the degree of hunchback will worsen, and recovery becomes more difficult with age. However, traditional spinal correction devices only provide simple positioning of the spine. Most people with spinal problems also experience shoulder shrugging and hunching, so simply positioning the spine often fails to comprehensively address these issues, resulting in limited corrective effects. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a spinal correction device. The technical problem to be solved by the present invention is that traditional spinal correction devices only limit the position of the spine.

[0026] like Figure 9As shown, both shoulder limiting components 22 include side L-shaped connecting blocks 221. The bottoms of the two side L-shaped connecting blocks 221 are respectively fixedly connected to the front sides of the two top U-shaped side guide plates 212.

The front side of the middle part of the outer side of the two side plates 222 is rotatably connected to the gears 226. The bottom of the front side of the outer side of the two side plates 222 is fixedly connected to the L-shaped inclined rod guide plate 227. The inner wall of the two L-shaped inclined rod guide plates 227 is slidably connected to the L-shaped inclined rod 228. The top middle part of the two L-shaped inclined rods 228 is fixed with the L-shaped inclined rod rack 229. The outer wall of the L-shaped inclined rod rack 229 set on the two L-shaped inclined rods 228 meshes with the outer wall of the two gears 226 respectively. The front bottom of the two rack telescopic rods 224 are provided with teeth, and the front sides of the two rack telescopic rods 224 respectively mesh with the outer walls of the two gears 226 back and forth.

[0027] like Figure 10 As shown, both waist fixing components 23 include L-shaped rotating rods 231. The outer walls of the two L-shaped rotating rods 231 are slidably connected to the inner walls of the two sliding cross plates 2112. The rear corners of the bottom of the two L-shaped rotating rods 231 are rotatably connected to the top of the two rotating blocks 2113 and to the side away from the corresponding push-pull block 2110. The front bottom of the outer side of the two L-shaped rotating rods 231 are fixedly connected to side connecting plates 232. The front and rear sides of the inner walls of the two side connecting plates 232 are slidably connected to columnar expansion rods 233. The inner ends of the two sets of columnar expansion rods 233 on the left and right sides extend through to the inner side of the two side connecting plates 232. The two on the left and the two on the right are respectively connected to the inner side of the two side connecting plates 232. Each columnar expansion rod 233 has a semi-circular waist fixing plate 234 fixedly connected to its inner end. The two semi-circular waist fixing plates 234 are symmetrically arranged. The outer ends of the two sets of columnar expansion rods 233 extend through to the outer side of the two side connecting plates 232. The inner ends of the two columnar expansion rods 233 on the left and the two columnar expansion rods 233 on the right are fixedly connected to each other. The middle of the inner side of the two spring connecting blocks 235 is fixedly connected to each other. The inner ends of the two sets of springs 236 on the left and the right are fixedly connected to the outer side of the two side connecting plates 232. The rear side of the outer wall of the two L-shaped rotating rods 231 is slidably connected to the inner wall of the two side guide blocks 2114.

[0028] During use, the patient's back is in close contact with the front sides of the two spinal correction panels 2116, with their spine positioned in the middle of the panels. Then, the electric push rod 14 is activated, pushing the convex lifting plate 114 upwards. This upward movement of the convex lifting plate 114 causes the two side lifting rods 113 to rise, and also causes rotation at the hinge points of the two sets of front rotating rods 17 and rear rotating rods 18. This series of actions causes the two sets of front rotating rods 17 and rear rotating rods 18 to rotate, thereby causing the front sides of the two sets of front rotating rods 17 to slide forward while rotating inside the two sets of front rotating rod guide plates 15. This sliding motion causes the two sets of push-pull rods 111 to push the push-pull plate 112 forward, and the overall forward displacement of the push-pull plate 112 further moves the correction assembly 2 forward. At this point, the front sides of the two spinal correction uprights 2116 are pushed by the patient's back, causing the two T-shaped push-pull plates 2115 to move backward. This causes the two sets of rotating diagonal rods 215 to rotate around the two columnar central crossbars 214. Consequently, the columnar connecting short rods 216 on the rear side of the two sets of rotating diagonal rods 215 push the two push-pull side rods 217 forward, which in turn pushes the two sets of columnar push-pull rod connecting plates 218, columnar push-pull rods 219, and push-pull blocks 2110 forward. Then, the two top push-pull blocks 2110 move forward, driving the two rack rod rear uprights 225 forward, which in turn pushes the two rack rod telescopic rods 224 forward. The two rack rod telescopic rods 224 then mesh with two gears 226 at their front bottoms and rotate. The rotation of gear 226 then meshes with the L-shaped rack 229 on the two L-shaped diagonal bars 228, causing the two L-shaped diagonal bars 228 to slide backward and downward along the L-shaped diagonal bar guide plate 227. This sliding action drives the two shoulder fixing plates 2211 to move towards the bottom of the diagonal, and the bottom of the two shoulder fixing plates 2211 is locked onto the patient's shoulder, thereby pressing down on the patient's shoulder and ensuring that the patient's shoulder does not shrug during the correction process, thus improving the stability of the correction.

[0029] Furthermore, the two push-pull blocks 2110 at the bottom move forward, causing the two rotating blocks 2113 to rotate. This rotation pushes the two L-shaped rotating rods 231 to rotate, bringing the inner front sides of the two L-shaped rotating rods 231 closer together. This action causes the two semi-circular lumbar fixation plates 234 to engage on both sides of the patient's waist. At this time, the two springs 236 are in a stretched state. Through the rebound force of the springs 236, the two semi-circular lumbar fixation plates 234 clamp and fix the patient's waist on both sides, ensuring that the patient's waist will not sway during the correction process, thereby enhancing the correction effect.

[0030] In addition, the rear side of the push control frame 1 can be fixed to the front side of the wall or a special correction frame to enable stable spinal correction operations for patients.

[0031] Working principle of this invention: The patient's back rests against the front of two spinal correction panels 2116, with the patient's spine positioned in the middle of the two spinal correction panels 2116. At this time, the electric push rod 14 is activated, which pushes the convex lifting plate 114 upward. The convex lifting plate 114 moves to the top, thereby driving the two side lifting rods 113 upward, and pulling the hinge joints of the two sets of front rotating rods 17 and rear rotating rods 18 to rotate, thus causing the two sets of front rotating rods 17 and rear rotating rods 18 to rotate. As the front side of the rotating rod 17 rotates, it slides forward on the inner side of the corresponding front rotating rod guide plate 15, thereby driving the two sets of push-pull rods 111 to push the push-pull plate 112 forward. The push-pull plate 112 moves forward as a whole, thereby driving the correction component 2 to move forward as a whole. At this time, the front sides of the two spinal correction uprights 2116 are pushed by the patient's back, causing the two spinal correction uprights 2116 to drive the two T-shaped push-pull plates 2115 to move backward, thereby causing the two sets of rotating diagonal rods 215 to move backward. The columnar central crossbar 214 rotates around its axis, causing the columnar connecting short rods 216 behind the two sets of rotating diagonal rods 215 to drive the two push-pull side rods 217 forward. This, in turn, causes the two sets of columnar push-pull rod connecting plates 218, columnar push-pull rods 219, and push-pull blocks 2110 to move forward. At this time, the two push-pull blocks 2110 at the top move forward, thereby driving the two rack rod rear uprights 225 to move forward, thus pushing the two rack rod telescopic rods 224 to move forward, and through the two rack rod telescopic rods 2110... The front bottom of 24 engages two gears 226, which rotate. The rotation of the two gears 226 then engages the L-shaped inclined bar racks 229 on the two L-shaped inclined bars 228, causing the two L-shaped inclined bars 228 to slide backward and downward along the L-shaped inclined bar guide plate 227. This causes the two shoulder fixing plates 2211 to move towards the bottom of the inclined bar 228, and thus the bottom of the two shoulder fixing plates 2211 is locked onto the patient's shoulder, pressing down on the patient's shoulder and ensuring that the patient does not shrug their shoulders during correction.

[0032] In addition, the two push-pull blocks 2110 at the bottom move forward, thereby driving the two rotating blocks 2113 to rotate. The rotation of the two rotating blocks 2113 pushes the two L-shaped rotating rods 231 to rotate, causing the inner front sides of the two L-shaped rotating rods 231 to move closer to each other. The front side of the L-shaped rotating rods 231 stretches the spring 236, which in turn causes the spring 236 to drive the spring connecting block 235 to move inward. This causes the two semi-circular waist fixing plates 234 to fit against the patient's waist on both sides. At this time, the two springs 236 are in a stretched state. Through the rebound force of the springs 236, the two semi-circular waist fixing plates 234 clamp and fix the patient's waist on both sides.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
