Description

Technical Field

[0001] The utility model relates to the field of spinal treatment, in particular to a treatment bed with a scoliosis correction stretching and fixing mechanism. Background Art

[0002] Traditional Chinese medicine calls it "the spine, the pillar of the human body." The spine is composed of 24 bones in the cervical, thoracic, lumbar, sacral and coccygeal regions, and is the second life center of the human body. It has the important functions of supporting the trunk, protecting the internal organs and spinal cord, and supporting body movement, and has a significant impact on life and health. Spinal disease is a general term for spinal injury, dysfunction, and pathological changes in the cervical, thoracic, lumbar, sacral, and coccygeal regions of the human body. It manifests itself in lesions of the bones, intervertebral discs, ligaments, and muscles of the spine, which in turn compress, pull and stimulate the spinal cord, spinal nerves, and blood vessels, leading to symptoms such as inability to stand upright, headaches, dizziness, blurred vision, memory loss, neck and shoulder pain, loss of appetite, nausea, vomiting, and lower limb weakness. Severe cases may even lead to paralysis. In recent years, the number of people suffering from the disease has increased, their age has become younger, and the symptoms have become more complex.

[0003] Among them, scoliosis is a common spinal disease. Scoliosis is also called scoliosis. It is a three-dimensional deformity of the spine, including abnormal sequences in the coronal, sagittal and axial positions. The spine of a normal person should be a straight line when viewed from the back, and the two sides of the trunk should be symmetrical. If the shoulders are not at the same height when viewed from the front or the back is uneven from the back, "scoliosis" should be suspected. At this time, a standing full spine X-ray should be taken. If the frontal X-ray shows that the spine has a lateral curvature of more than 10 degrees, scoliosis can be diagnosed. Mild scoliosis usually does not cause obvious discomfort, and there is no obvious body deformity in appearance. Severe scoliosis will affect the growth and development of infants, young children and adolescents, causing physical deformation. In severe cases, it can affect cardiopulmonary function and even involve the spinal cord, causing paralysis. Mild scoliosis can be observed, and severe cases require surgical treatment. Scoliosis is a common disease that harms adolescents and children. The key is early detection and early treatment.

[0004] Currently, the early treatment of scoliosis mainly adopts corrective treatment. Doctors use external force to adjust the vertebrae to restore normal alignment and gradually correct the scoliosis.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] Figures 1 to 6 Shown is an embodiment of the utility model.

[0027] Embodiment 1:

[0028] like Figure 1 , 2As shown in Figure 4, a treatment bed with a scoliosis correction stretching and fixing mechanism includes a base 1, a column 2 is installed on the upper side of the base 1, a shoulder bed body 3 and a waist bed body 4 are installed on the upper side of the column 2 in sequence, the shoulder bed body 3 is installed on the front side of the column 2 for horizontal rotation, the waist bed body 4 is installed on the rear side of the column 2 for up and down swinging, and fixing parts are installed on both sides of the waist bed body 4, and a waist fixing belt 5 is installed between the two fixing parts. When performing scoliosis correction, the patient's waist is fixed to the waist by the waist fixing belt 5, and then the patient can fix the shoulder by hugging the shoulder bed body 3, and the doctor adjusts the originally curved spine to a vertical state by rotating the shoulder bed body 3. The lumbar bed 4 can be swung up and down with the column 2. After the spine is adjusted, the lumbar bed 4 is swung up and down to stretch the spine. When the lumbar bed 4 swings downward, the spine is stretched, thereby increasing the gap between the vertebrae, so that each vertebra can be reset. In the process of cyclic up and down swinging, the doctor can correct the vertebrae through correction techniques. The entire correction process can correct the patient's spine and stretch the vertebrae with the help of the treatment bed, so that the doctor can reset the vertebrae and gradually restore the patient's spine to a normal state.

[0029] The front side of the shoulder bed 3 is installed with a head bed 6, and the front side of the head bed 6 is installed with a handle 7; the back side of the waist bed 4 is installed with a leg bed 8, and the upper side of the leg bed 8 is provided with a leg fixing belt. By providing the leg bed 8 and the leg fixing belt, the patient's legs can be supported and fixed, so that the patient is more comfortable during treatment, and when the waist bed 4 swings up and down, the legs are fixed, and the patient's spine is stretched in conjunction with the handle 7. Every time the waist bed 4 swings downward, the spine can be effectively stretched. By providing the head bed 6, support can be provided for the patient's head.

[0030] Embodiment 2:

[0031] On the basis of Example 1, Figure 5 , 6 As shown, the lower sides of the left and right sides of the lumbar bed body 4 are horizontally installed with fixing sleeves 9, and the two fixing members are detachably connected to the two fixing sleeves 9. By providing the fixing sleeves 9, it is easy to install and remove the fixing members, so that when the treatment bed is used to treat scoliosis, the fixing members can be installed for treatment, and when other treatments are performed, the fixing members can be removed from the fixing sleeves 9.

[0032] The fixing part includes a fixed upright rod 10 and a fixed shaft 11. An insertion rod 12 is horizontally arranged at the lower end of the fixed upright rod 10, and the insertion rod 12 is inserted into the fixed sleeve 9. A horizontal plate 13 is horizontally arranged at the upper end of the upright rod. Vertical plates 14 are vertically arranged on the upper sides of the front and rear sides of the horizontal plate 13. Round holes are aligned on the two vertical plates 14. The fixed shaft 11 is horizontally rotatably arranged between the two vertical plates 14, and the two ends of the fixed shaft 11 pass through the round holes of the two vertical plates 14 respectively. The front end of the fixed shaft 11 is connected to a first knob 15 on the front side of the front vertical plate 14, and the fixed shaft 11 is coaxially connected to a ratchet 16 on the rear side of the rear vertical plate 14, and a locking claw is installed on the rear side of the rear vertical plate 14 on the lower side of the ratchet 16; the end of the waist fixing belt 5 is connected to the fixed shaft 11. When fixing the patient's waist, the patient lies face down on the treatment bed, and then the middle part of the waist fixing belt 5 is attached to the upper side of the patient's waist, and then the two ends of the waist fixing belt 5 are fixed to the two fixed shafts 11 respectively. The fixing method can be Velcro, and the Velcro hook surface is set on the surface of the fixed shaft 11, and the Velcro fur surface is set on the waist fixing belt 5, so that the end of the waist fixing belt 5 and the fixed shaft 11 can be fixed simply and quickly. After the waist fixing belt 5 is fixed, by turning the first knob 15, the waist fixing belt 5 can be driven to wrap around the fixed shaft 11, thereby tightening the waist fixing belt 5, so that the waist fixing belt 5 can fix the patient's waist on the waist bed body 4. The fixed shaft 11 can be prevented from rotating by cooperating with the ratchet 16 and the stop claw.

[0033] The stop pawl includes a horizontal rod 17, a pawl 18, a fixed block 19 and a spring 20. One end of the horizontal rod 17 is connected to the rear side of the vertical plate 14 through a rotating shaft 21 for vertical rotation. The pawl 18 is arranged on the upper side of the horizontal rod 17. The fixed block 19 is connected to the rear side of the vertical plate 14 below the horizontal rod 17. The upper end of the spring 20 is connected to the lower side of the horizontal rod 17, and the lower end is connected to the upper side of the fixed block 19. When the first knob 15 is turned, the fixed shaft 11 and the ratchet 16 rotate together at the same time. When the ratchet 16 rotates forward, the inclined surface of the teeth on the ratchet 16 cooperates with the inclined surface of the pawl 18 to support the horizontal rod 17 to move downward, compressing the spring 20, so that the ratchet 16 can rotate normally. At the same time, the vertical surface of the teeth of the ratchet 16 cooperates with the vertical surface of the pawl 18 to prevent the ratchet 16 from rotating in the reverse direction. When the waist fixing belt 5 needs to be loosened, the horizontal rod 17 is pressed down to separate the claw buckle 18 and the ratchet 16, so that the fixing shaft 11 can be rotated arbitrarily.

[0034] A threaded hole that penetrates inside and outside is provided on the side wall of the fixed sleeve 9, and a threaded column 22 is connected to the threaded hole in a matching manner. One end of the threaded column 22 is connected to the insertion rod 12 in the fixed sleeve 9, and the other end is connected to the second knob 23 on the outside of the fixed sleeve 9. By providing the threaded column 22 and the threaded hole in cooperation, after the insertion rod 12 is inserted into the fixed sleeve 9, the threaded column 22 can be driven into the fixed sleeve 9 by rotating the second knob 23 to hold the insertion rod 12, thereby preventing the insertion rod 12 from slipping out of the fixed sleeve 9.

[0035] The first rotating shaft 24 is provided on both the left and right sides of the upright column 2, and two rotating plates 25 are provided on the front side of the lumbar bed body 4.
