Description

Technical Field

[0001] The invention relates to traction treatment of cervical spondylosis and is a cervical vertebra lying position traction device specially used for treating cervical spondylosis. Background Art

[0002] At present, cervical spondylosis is a common and frequently occurring disease. The effective clinical method for treating cervical spondylosis is cervical traction therapy. There are two types of traction devices for treating cervical spondylosis: weighted traction and airbag cervical collar traction. Weighted traction is to use a special jaw strap to wrap and tie up the head of the traction patient from the mandible, cheek, occipital bone and mastoid, and use a rope to redirect the pulley to hang a weight for traction. Inflatable cervical collar traction is to use a special collar made of plastic or gel material to put on the neck of the traction patient. The lower end of the collar is stuck on the shoulder and neck of the traction patient, and the upper end is stuck on the mandible and occipital bone. After the collar is inflated, it expands longitudinally to achieve traction. Although both of these two traction methods can achieve the purpose of traction treatment, the disadvantage is that the points of action of the force are mainly concentrated on the neck. At the mandible, because the mandible is basically perpendicular to the cervical spine, the jaw strap and collar will not slip when traction is applied, so it is subjected to long-lasting and severe suspension or pressure. The force acting on the occipital bone and mastoid processes on both sides of the cervical spine is easy to slip upward because the occipital bone and mastoid processes are gently convex and easy to slip upward. Therefore, the force on the front of the neck is greater than that on the back of the cervical spine that really needs traction. The entire neck is subjected to horizontal force. In order to maintain a normal cervical posture, the traction person must use force to keep the neck straight, and the muscles and ligaments are in a state of tension. During the traction treatment, the mandible is subjected to suspension and pressure that is particularly unbearable, and even compresses the carotid artery, resulting in insufficient blood supply to the brain during traction. The cervical spine of patients with cervical spondylosis is often deformed, some are too bent, and some are rigid. The counterweights and cervical collar traction devices are powerless, so the treatment effect is not ideal. Summary of the Invention

[0003] In order to overcome the shortcomings of the above-mentioned existing traction treatment instruments, the purpose of the present invention is to provide a cervical supine traction device for traction treatment of cervical spondylosis, which uses an adjustable cervical curvature regulating plate to traction the neck and shoulder of the patient's lower cervical spine, and uses a neck diameter regulating lock to lock the occipital mastoid process of the upper cervical spine, so as to implement traction treatment on the cervical spine. It can control and correct the physiological curvature of the cervical spine, and at the same time make the traction force directly act on the upper and lower ends of the cervical spine of the patient undergoing traction treatment, so that the cervical spondylosis patients receiving traction treatment no longer have to endure the pain of being strangled and oppressed by the lower jaw, and can rest or sleep comfortably during effective traction treatment.

[0004] The technical solution adopted by the present invention to solve its technical problems is that the cervical lying traction device consists of a base, an adjustable cervical curvature control board, a pillow support, a neck diameter control lock, etc. On the bottom surface of the front sides of both ends of the base, there are slideways. At the front end of the slideway, there is an adjustment screw positioning seat. On the slideway, there is a sliding fulcrum seat. At both ends of the front lower side of the pillow support corresponding to the sliding fulcrum seat, there are pillow support fulcrums. The pillow support fulcrums are connected to the sliding fulcrum seat through a fulcrum connecting shaft to install the pillow support on the base. The fulcrum shaft hole of the pillow support is at the bottom most front of the pillow support. On both sides of the pillow support, there are ratchets for adjusting the reset spring force. The reset spring is sleeved on the ratchet shaft. One end of the reset spring is stuck on the bottom surface of the base, and the other end is stuck on the ratchet shaft. On the front side of the base, an adjustable cervical curvature control board is installed through a height adjustment guide post. The plate surface inclination angle and relative height of the adjustable cervical curvature control board can be freely adjusted to correct and control the cervical vertebra with an abnormal physiological curvature. On the top of the pillow support, there is a concave arc-shaped pillow surface. On the installation groove in the middle of the front part of the pillow support, there is a neck diameter control lock. Inside the front side frame plate of the pillow support, there are symmetrically arranged inclined centripetal trajectory teeth. In the middle of the frame plate, there is a central installation hole. At the center of the central section vertical rib connecting plate of the neck diameter control lock, there is a lock installation hole. The central installation hole and the lock installation hole are connected through a connecting shaft to install the neck diameter control lock on the pillow support. The neck diameter control lock is composed of several ∟-shaped clamping flaps and two control clamping flaps connected by a connecting shaft to form a soft-connected flexible joint strip-shaped continuous piece that is bent by gathering. Pull up the two ends of the soft-connected flexible joint strip-shaped continuous piece, and adjust the corresponding levels of the centering positioning push rod to press against the inclined centripetal trajectory teeth to form a neck diameter control lock that meets the needs of people with different thickness cervical vertebrae. The bent arc segments of the ∟-shaped clamping flaps of the neck diameter control lock gather to form a clamping support. On the straight sections of each ∟-shaped clamping flap and under the control clamping flap, there are vertical rib connecting plates. Both ends of the vertical rib connecting plates are provided with connecting shaft holes and are connected to each other by a connecting shaft. Under the side section vertical rib connecting plate, there is a centering positioning push rod for adjusting and controlling the centripetal radius of the neck diameter control lock. Under the control clamping flap, there is a pushing pull rod. At the lower end of the pushing pull rod, there is a fork. The fork is connected to the centering positioning push rod. Press down the control clamping flap to push the fork to move, and flatten the neck diameter control lock and the clamping support into a soft-connected flexible joint strip-shaped continuous piece. During use, the soft-connected flexible joint strip-shaped continuous piece is wound around the semi-perimeter of the cervical vertebra of the traction treatment patient to form a neck diameter control lock. The clamping support supports and clamps the occipital bone and mastoid process of the traction treatment patient, and has a large contact area with them, so the discomfort during the traction treatment process is very slight. One end of the screw is fixed in the screw positioning seat, and the other end is screwed into the sliding fulcrum seat. Rotating the screw pulls the sliding fulcrum seat, that is, the relative distance between the neck diameter control lock and the adjustable cervical curvature control board is adjusted to suit the cervical vertebra length of the traction treatment patient. Rotating the ratchet shaft can apply force or unload the reset spring, making the rear side of the pillow support just lift up and offset the traction force less. The head is rested on the pillow support, and the occipital bone and mastoid process of the traction treatment patient are firmly clamped and anchored on the pillow support by the neck diameter control lock and the clamping support. Although the rear side of the pillow support needs to drop, it is pulled by the cervical vertebra like a rope, making the pillow support and the cervical vertebra stay at the traction balance point.The weight of the head is converted into traction force to effectively traction the cervical vertebrae.

[0005] Due to the adoption of the above design scheme, the beneficial effects of the present invention are as follows: It uses an adjustable cervical curvature control plate to correct and control the cervical vertebrae of the traction-treated patients to conform to the normal physiological curvature, and positions and clamps the neck and shoulders at the lower end of the cervical vertebrae. The occipital mastoid at the upper end of the cervical vertebrae is locked by a cervical diameter control lock and a retaining bracket, and traction treatment is performed on the cervical vertebrae. The traction force application points directly act on the upper and lower ends of the cervical vertebrae. The traction treatment is convenient, easy, comfortable and effective, enabling patients with cervical spondylosis undergoing traction treatment to no longer endure the pain of strangling and pressing the lower jaw. The lying-position cervical traction device is an ideal device for traction treatment of cervical spondylosis. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The cervical lying traction device 25 consists of a base 1, an adjustable cervical curvature control board 9, a pillow support 2, a neck diameter control lock 3, etc. Four height-adjusting guide columns 28 are installed on the front side edge of the base 1 made of hard plastic by one-time injection molding to fixedly install the adjustable cervical curvature control board 9. Symmetrical slideways 4 are injection molded on the bottom surfaces of the front sides of both ends of the base 1. A sliding fulcrum seat 5 is installed on the slideways 4. A screw rod positioning seat 11 is installed at the front outer part of the slideways 4. One end of the screw rod 12 is fixed in the screw rod positioning seat 11 by a snap spring or a spare cap, and the other end is screwed into the sliding fulcrum seat 5. The pillow support 2 is injection molded at one time. A coaxial pillow support fulcrum 6 is injection molded under the front side edge of the pillow support 2 corresponding to the sliding fulcrum seat 5. The pillow support fulcrum 6 and the sliding fulcrum seat 5 are connected by a fulcrum connecting shaft 7 to install the pillow support 2 on the base 1. The pillow support 2 is in a single-sided cantilever shape, and there are no fulcrum suspension points on other peripheries. The headrest is on the pillow support 2. The occipital mastoid of the patient undergoing traction treatment is firmly locked and anchored on the pillow support 2 by the neck diameter control lock 3 and the retaining bracket 23. Although the rear side of the pillow support 2 needs to drop, it is pulled by the cervical vertebra like a rope, so that the pillow support 2 and the cervical vertebra stay at the tensile balance point. The concave arc-shaped pillow surface 10 of the pillow support 2 is injection molded into a concave arc shape to accommodate the retaining bracket 23 composed of the inverted L-shaped clamping petals 15 of the neck diameter control lock 3. An installation groove for the neck diameter control lock 3 is left inside the front side frame plate 20 of the pillow support 2.

Oblique centripetal trajectory locking teeth 14 are injection molded inside the front side frame plate 20. Centering positioning ejector rods 24 are injection molded under the two side section vertical rib connecting plates 30. The lower end of the centering positioning ejector rod 24 presses and locks a certain level of the oblique centripetal trajectory locking teeth 14 to determine the formation of the neck diameter control lock 3 with a corresponding radius. The connecting plate shaft hole 19 on the outside of the side section vertical rib connecting plate 30 is connected to the connecting plate shaft hole 19 of the control clamping petal 29 through a shaft pin. The lower surface of the control clamping petal 29 is connected to a push connecting rod 21 by another shaft pin. The lower end of the push connecting rod 21 is connected to a fork 22. The fork 22 and the centering positioning ejector rod 24 are connected by a shaft pin. When the control clamping petal 29 is pressed down, the fork 22 acts to pull out the centering positioning ejector rod 24 from the oblique centripetal trajectory locking teeth 14, and the formed neck diameter control lock 3 is laid flat into a soft connected flexible joint strip 13. A corresponding round hole 31 is drilled on the side plate of the pillow support 2. One end of a ratchet wheel 26 is inserted into the round hole 31. One end of a ratchet shaft 27 is inserted into the other end of the ratchet wheel 26. The other end of the ratchet shaft 27 is fixed by a bracket. A return spring 8 is sleeved on the ratchet shaft 27. One end of the return spring 8 is stuck on the ratchet shaft 27, and the other end is stuck on the bottom surface of the base 1.
