Description

Technical Field

[0001] This utility model belongs to the field of medical equipment, specifically, it relates to a cervical traction device. Background Technology

[0002] Cervical spondylosis is a disease caused by degenerative pathological changes in the cervical spine. The main causes are long-term strain on the cervical spine, bone hyperplasia, herniated discs, thickened ligaments, etc., which compress the cervical spinal cord, nerve roots, and vertebral arteries. Symptoms include neck pain and stiffness, numbness and weakness in the limbs, dizziness, nausea, and vomiting. In severe cases, it can manifest as blurred vision, tachycardia, and difficulty swallowing.

[0003] For the treatment of cervical spondylosis, most patients can control symptoms, reduce recurrence, and improve their quality of life through non-surgical treatments such as physical therapy (traction), exercise therapy, and drug therapy.

[0004] Cervical traction is a treatment that uses manual techniques or instruments to apply external force to the cervical spine, causing the articular surfaces to separate and thus achieving therapeutic goals. The correct method of cervical traction mainly includes fixation and parameter selection, including the method, angle, weight, and traction time.

[0005] Chinese patent CN2790431Y discloses a suspended lever home cervical traction device, an instrument for traction of the cervical spine for health care or treatment, belonging to the category of health care and medical products. Existing cervical traction devices are large, complex in structure, and inconvenient to operate, making them unsuitable for home use. This utility model has a pulling device and a head fixing device respectively set at both ends of the lower part of a lever. A suspension device is set on the lever, with the connection point of the suspension device biased towards the head fixing device side, forming a force-saving lever. In use, this utility model is suspended on a load-bearing component, and the traction sleeve is fixed to the head and neck area. The person being tractioned hangs a weight on the hook of the pulling device, and a 2 kg weight can achieve a 10 kg traction force.

[0006] The above technical solution has the following drawbacks:

[0007] Most cervical traction frames on the market today have the above-mentioned structure. Although they can fix the head (cervical spine) and achieve the function of stretching and correction, for users, the traditional suspension head fixation strap will deflect (rotate) during use, affecting the patient's correction experience. At the same time, the method of manually suspending heavy objects (such as dumbbell plates) is also quite laborious. Utility Model Content

[0008] To address the above deficiencies, this utility model provides a cervical traction device, including a traction frame and a traction rope. A telescopic frame is fixed to the right side of the traction frame, and a telescopic rod is movably installed inside the telescopic frame. A frame rod is movably connected to the top of the telescopic rod through a limiting pivot. Fixed pulleys I are installed at both ends of the frame rod, and a guide rod for fixing fixed pulleys II is also installed on the right side of the telescopic frame.

[0009] An adjustment device is installed on the right side of the traction frame. The adjustment device is used to tighten and loosen the traction rope by rotating and winding. The end of the traction rope away from the adjustment device passes through a fixed pulley II and two fixed pulleys I in sequence and is connected to a head traction belt.

[0010] Furthermore, the height position of the telescopic rod is fixed between the telescopic rod and the telescopic frame by a limiting member.

[0011] Furthermore, a set of foot supports is also installed on the side of the traction frame near the adjustment device.

[0012] Furthermore, the head traction strap is in the shape of a coat hanger, with an elastic band fixed to the bottom of the hanger to support the patient's chin;

[0013] A sliding rod is also installed at the hanger, and the end of the sliding rod near the telescopic rod engages with a groove opened on the same side of the telescopic rod.

[0014] Furthermore, a seat cushion is installed on the top of the traction frame.

[0015] Furthermore, an emergency switch for shutting off the adjustment equipment is installed on the side of the telescopic frame.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. For head traction straps that suspend the head, the sliding bar can be used to keep them stable and prevent the patient's head from swinging randomly during correction, which would affect the traction effect and keep the head stable.

[0018] 2. The traction rope can be tightened or loosened by adjusting the winding of the device, thereby adjusting the height of the head traction belt to suit the different heights and needs of patients. An emergency switch is also added so that the winding of the traction rope can be stopped when the patient feels uncomfortable. Attached Figure Description

[0022] To facilitate understanding of this utility model, the device of this utility model will be described more fully below with reference to the accompanying drawings. Embodiments of the device are shown in the drawings. However, this device can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1

[0025] like Figs. 1-2 As shown, this embodiment provides a cervical traction device, including a traction frame 1 and a traction rope 7. A cushion 2 for improving patient comfort is installed on the top of the traction frame 1. A telescopic frame 5 is fixed on the right side of the traction frame 1. A matching telescopic rod 9 is movably installed inside the telescopic frame 5. The height position of the telescopic rod 9 is fixed between the telescopic rod 9 and the telescopic frame 5 by a limiting member 15. In this embodiment, the limiting member 15 is a V-shaped spring structure commonly used in umbrellas. The spherical limiting protrusion (the end of the V-shaped spring) installed on the telescopic rod 9 is engaged with several equally spaced circular grooves on the corresponding surface of the telescopic frame 5 to achieve the adjustment of the height of the top frame rod 6.

[0026] The top of the telescopic rod 9 is movably connected to the frame rod 6 via the limiting pivot 13. Both ends of the frame rod 6 are equipped with fixed pulleys I. The right side of the telescopic frame 5 is also equipped with a guide rod 10 for fixing the fixed pulleys II. It should be noted that, since each patient's actual situation is different, the angle of the frame rod 6 may also need to be adjusted. Therefore, the limiting pivot 13 with limiting function is used to achieve the fixing effect after rotation adjustment (a traditional self-locking pivot can be used).

[0027] An adjustment device 4 is installed on the right side of the traction frame 1. The adjustment device 4 is used to tighten and loosen the traction rope 7 by rotating and winding. The adjustment device 4 is a forward and reverse motor, and a reducer is installed at the output end. The motor compartment for protection is provided on the outside. After the traction rope 7 is fixed to the output end by a clamp, it extends out of the retraction opening in the motor compartment. The end of the traction rope 7 away from the adjustment device 4 passes through a fixed pulley II and two fixed pulleys I in sequence and is connected to a head traction belt 8. The head traction belt 8 is in the shape of a coat hanger. An elastic band for supporting the patient's chin is fixed at the bottom of the coat hanger.

[0028] A sliding rod 12 is also installed on the clothes hanger. The end of the sliding rod 12 near the telescopic rod 9 is engaged with the groove 14 opened on the same side of the telescopic rod 9. Its function is to ensure that the clothes hanger is in a stable state (i.e., it will not sway from side to side, causing instability of the patient's head and affecting the traction effect) by limiting the movement of the head traction belt 8.

[0029] A set of foot supports 3 is also installed on the side of the traction frame 1 near the adjustment device 4 for supporting the patient's feet.

[0030] It should be noted that an emergency switch 11 for shutting off the adjustment device 4 (connected to the control switch of the adjustment device 4) is installed on the side of the telescopic frame 5. When the patient feels uncomfortable, the emergency switch 11 can be used to stop the winding of the traction rope 7.

[0031] The patient sits on the side closest to the telescopic frame 5. The doctor adjusts the telescopic rod 9 to a suitable height position, then fixes the patient's head with the head traction strap 8. Subsequently, the doctor controls the adjustment device 4 to retract the cable, causing the traction rope 7 to stretch the head traction strap 8 upward until it reaches the suitable position, thus completing the traction of the patient's cervical spine.

[0032] Example 2

[0033] The difference from Embodiment 1 is that the telescopic rod 9 and the telescopic frame 5 are replaced by an electric push rod, which can achieve more precise height adjustment. However, a vertical rod should be fixed at the telescopic end of the electric push rod for mounting the frame rod 6. The electric push rod is existing technology and will not be described in detail. The accompanying drawings are also omitted.

[0034] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
