Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a cervical and lumbar traction device. Background Technology

[0002] Traction devices play a significant role in the medical field. They can reduce the pressure of intervertebral discs on nerves and relieve pain, such as lumbar and cervical traction devices used for traction therapy in corresponding areas. They can also correct spinal facet joint disorders, relax muscles, improve joint mobility, and promote bone repositioning and healing. They are commonly used auxiliary treatment tools in orthopedics and rehabilitation departments.

[0003] However, traditional traction methods mostly use linear traction, which is monotonous, has limited applicability, and poor efficacy. Furthermore, due to individual differences, the spinal length and physiological curvature of different patients are not entirely consistent, making it difficult to provide differentiated treatment for each patient.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a cervical and lumbar traction device. (Refer to...) Figure 1 , Figure 2 and Figure 3 The equipment includes a frame 1, a power unit 2, a control system 3, and a display screen 4. The top of the frame 1 is covered by an upper housing 5. The power unit 2 is installed at the lower part of the frame 1, the control system 3 is installed in the middle of the frame 1, and the display screen 4 is installed on the upper housing 5. The frame 1 also includes a transformer 6 and a switch with a socket 15. The transformer 6 provides a safe voltage to the control system 3. The control system 3, transformer 6, and switch with a socket 15 are connected by cables. The power unit 2 increases traction through gear reduction. The power unit 2 includes a winding wheel 203 with a flexible steel cable wound on it. The frame 1 is equipped with a column 13, and a first guide pulley 7 is installed on the upper housing 5. A second guide pulley 8 and a fastening sleeve 12 are installed on the column 13. The fastening sleeve 12 is used to adjust and lock the height of the second guide pulley 8 on the column 13. The flexible steel cable passes through the first guide pulley 7 and extends to the second guide pulley 8. A protractor 9 is fixed on the second guide pulley 8 to measure the traction angle of the flexible steel cable, thereby meeting the needs of patients with multiple physiological curvatures. Four lockable universal casters 16 are installed at the bottom of the frame 1 to facilitate the movement and locking of the traction device on the plane.

[0026] Reference Figure 4The power unit 2 includes a base plate and a servo motor 202. A first bracket 215 and a second bracket 216 are vertically arranged on the base plate. The end of the servo motor 202 is fixed on the side wall of the first bracket 215. The winding wheel 203 is coupled to the middle of the first bracket 215 and the second bracket 216 through a shaft. A force sensor 214 is fixed on the first bracket 215. The force sensor 214 is used for traction force detection and data feedback. A motor gear 204 is fixed to the end of the servo motor 202, and a large gear 207 is connected to the end of the winding wheel 203. The motor gear 204 and the large gear 207 are located on the same side of the first bracket 215. A connecting plate 206 is fixed to one end of the shaft of the large gear 207, and an intermediate gear 205 is fixed to the connecting plate 206. The intermediate gear 205 is used to connect the motor and the large gear 207. A telescopic spring 210 and a flexible steel cable 209 are respectively connected to the two sides of the end of the connecting plate 206 away from the large gear 207. The end of the telescopic spring 210 away from the connecting plate 206 is connected to the first bracket 215. An electromagnetic attractor 208 is also fixed on the first bracket 215. The flexible steel cable 209 can be attracted to the electromagnetic attractor 208. Thus, by the attraction and disengagement of the electromagnetic attractor 208, the intermediate gear 205 rotates clockwise and counterclockwise around the shaft of the large gear 207 at small angles.

[0027] When the electromagnetic attractor 208 is energized, it attracts the flexible steel cable 209. The intermediate gear 205 rotates counterclockwise around the large gear 207 and meshes with the motor gear 204 and the large gear 207 respectively. When the electromagnetic attractor 208 is de-energized and in a free state, the reaction force of the telescopic spring 210 causes the connecting plate 206 to rotate clockwise around the large gear 207. Then the intermediate gear 205 separates from the motor gear 204 and the large gear 207 respectively.

[0028] Reference Figure 5 A coil spring 211 is provided at the rotating shaft end of the large gear 207. The coil spring 211 is located outside the connecting plate 206. When the large gear 207 is in a free state, the coil spring 211 drives the soft flexible rope 10 to wrap around the winding wheel 203 in an orderly manner through the winding wheel 203, thereby preventing the flexible rope 10 from getting tangled.

[0029] Furthermore, an auxiliary wheel 212 is provided on one side of the winding wheel 203. A tension spring 213 is attached to the connecting rod on the right side of the auxiliary wheel 212. The other end of the tension spring 213 is fixed to the base plate. The flexible rope 10 extends upward through the auxiliary wheel 212, connects to the first guide pulley 7, and leads to the second guide pulley 8. A connector 11 is provided at the end of the flexible rope 10, which is used to suspend the tension strap. An indicator light 14 is provided at the top of the column 13, which is used to indicate the operation of the equipment.

[0030] The implementation principle of a cervical and lumbar traction device according to this application embodiment is as follows: When in use, the patient is fixed to the device with straps. According to the patient's specific condition, the height of the second guide pulley 8 is adjusted by the fastening sleeve 12, and the traction force and time are set by the control system 3. After the device is started, the servo motor 202 and the large gear 207, the intermediate gear 205 and the motor gear 204 work together to perform multi-angle traction on the patient's cervical or lumbar spine. During the traction process, the display screen 4 displays parameters such as traction time and force in real time, and medical staff can adjust them as needed.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
