A physical therapy device for cervical traction correction

Technical Field

The invention relates to the technical field of cervical vertebrae physiotherapy instruments, and in particular to a physiotherapy device for cervical vertebrae traction correction.

Background technique

At present, with the progress of society and the acceleration of modernization, especially the popularization of computers, more and more people are working in a sitting position, and the incidence of cervical spondylosis is also on the rise, so the demand for cervical traction devices is also increasing. The current cervical traction devices directly act on the mandible, lifting the mandible upward to achieve the purpose of cervical correction, but the force during traction is large and the time is long. Such long-term force acting on the mandible is easy to cause damage to the mandible, and long-term correction also makes the patient unable to speak or eat, resulting in a poor patient experience.

Summary of the invention

The purpose of the present invention is to provide a physical therapy device for cervical traction correction. Long-term cervical correction is not easy to cause damage to the patient's mandible. During the correction process, the patient can talk and eat, and the patient has a good experience.

In order to solve the above technical problems, the present invention adopts the following solutions:

Example 1

A physical therapy device for cervical traction correction, characterized by comprising:

A traction device acts on the skull and can perform multi-directional traction in any oblique direction in the vertical or circumferential plane to correct the natural physiological curvature of the cervical spine and maintain the natural physiological curvature of the cervical spine;

The top pressure device is installed on the traction device and acts on the back of the neck to keep the cervical spine in a natural physiological curvature;

The carrying frame 6 is arranged on the upper body of the patient and is used to support the traction device.

In this embodiment, as shown in Figure 1, the physical therapy device consists of three parts: a traction device, a pressure device and a backpack 6. The shape of the backpack 6 is adapted to the contour of the upper body of the human body. The backpack 6 is generally made of hard plastic, which is light in weight and can reduce the patient's load. During traction correction, the patient first wears the backpack 6 and fixes it on the upper body. The backpack 6 is mainly used to support the traction device, so that the traction reaction force generated by the traction device on the skull acts on the shoulders and back of the human body, and the supporting effect is better. At the same time, the patient can carry the entire physical therapy device to perform correction operations anywhere, and the correction of the cervical spine can be completed without going to the hospital, which makes the device more flexible in use. After the backpack 6 is worn, the traction device is installed at a specific position of the backpack 6, and then the pressure device is installed. After all devices are installed, traction correction can begin. The force point of the traction device is located on the skull. The traction device corrects the cervical spine by applying force in multiple directions along any oblique direction in the vertical or circular plane, so that each vertebral structure is restored to a normal state, and the cervical sequence is restored to a natural physiological curvature, which ultimately plays an effective corrective role and ultimately allows the cervical spine to maintain a natural physiological curvature, achieving the purpose of traction correction of the cervical spine. Multi-directional refers to vertically upward or downward and obliquely upward or/and downward, which can be determined according to the specific bending direction of the cervical spine. At the same time, the top pressure device acts on the back of the neck to assist the cervical spine in maintaining a natural physiological curvature, and finally completes the correction traction work. Compared with the prior art, the force of the traction device of this scheme does not act directly on the chin, but on the skull, so that the patient's mandibular part will not be damaged during the long-term traction correction process. At the same time, the patient can open his mouth to eat or talk during the correction process, so that the patient's experience is better and the applicability is stronger.

The fixed ring 2 is detachably connected to the patient's skull, the lower end of the driving member is movably connected to the backpack frame 6, and the upper end is movably connected to the fixed ring 2. The power source 11 provides power for the driving member to pull the natural physiological curvature of the cervical spine and maintain the natural physiological curvature of the cervical spine.

Specifically, the traction device consists of a fixing ring 2, a driving member and a power source 11. The power source 11 is installed on the back frame 6. The power source 11 provides power for the driving member. The fixing ring 2 is made of medical stainless steel. The fixing ring 2 is adapted to the size of the patient's skull. As shown in Figure 2, the fixing ring 2 is fixed to the skull by a plurality of medical skull nails 15. The skull nails 15 are generally made of titanium alloy, carbon fiber or stainless steel. The upper and lower ends of the driving member are movably connected to the fixing ring 2 and the back frame 6 respectively, so that the driving member can exert force in multiple directions to adapt to cervical spine correction with various bending angles. The driving member is powered by the power source 11, and the driving member acts on the fixing ring 2, driving the fixing ring 2 from different directions to pull the cervical spine to achieve the purpose of correction. The skull traction mainly restores the sequence between vertebral segments to the normal sequence and fixes and maintains the segment where the tissue structure grows stably again, so as to finally maintain the natural physiological curvature of the cervical spine.

Optionally, the driving member includes four hydraulic rods connected to the power source 11, namely the first hydraulic rod 24, the second hydraulic rod 23, the third hydraulic rod 4, and the fourth hydraulic rod 22.

Specifically, the driving member includes a first hydraulic rod 24, a second hydraulic rod 23, a third hydraulic rod 4, and a fourth hydraulic rod 22. The four hydraulic cylinders are connected to the power source 11 through a high-pressure pipe. The power source 11 is a hydraulic pump. The hydraulic pump is installed on the backpack frame 6. The controller 10 and the battery 26 can also be installed on the backpack frame 6. The battery 26 provides power for the controller 10 and the hydraulic pump. The controller 10 can control the hydraulic pump to provide different power to the four hydraulic rods, so that the telescopic length of each hydraulic rod can be controlled, and then the traction force of each hydraulic rod can be controlled. The first hydraulic rod 24 and the second hydraulic rod 23 are located on the left side, and the third hydraulic rod 4 and the fourth hydraulic rod 22 are located on the right side. The lower ends of the first hydraulic rod 24 and the third hydraulic rod 4 are connected to the backpack frame 6 at the front chest position, and the lower ends of the second hydraulic rod 23 and the fourth hydraulic rod 22 are connected to the backpack frame 6 at the shoulder position, so that the reaction forces of the four hydraulic rods all act on the shoulder and the driving part.

As shown in Figure 3, the rotating member 3 includes a rotating seat 17 and a rotating ball 16. The rotating ball 16 is movably connected to the rotating seat 17. A connecting rod 19 is provided on the side wall of the rotating seat 17. The connecting rod 19 is detachably connected to the fixed ring 2 and the back frame 6. The cooperation between the rotating seat 17 and the rotating ball 16 enables the four hydraulic rods to achieve multi-directional telescopic movement, which can be vertically upward or downward, or tilted upward or downward, which has greater flexibility in the traction direction of the cervical spine. At the same time, through the action of the connecting member, the fixed ring 2 and the back frame 6 of different sizes can be easily replaced to suit different patients.

Optionally, the depth of the rotating cavity 18 is smaller than the radius of the rotating ball 16. Specifically, the rotating cavity 18 is spherical, has an opening, and the diameter of the opening is smaller than the diameter of the rotating ball 16. At the same time, the depth of the rotating cavity 18 is smaller than the diameter of the rotating ball 16, so that the rotating ball 16 will not fall out of the rotating cavity 18, ensuring the connection stability between the hydraulic rod and the fixing ring 2 and the backpack frame 6.

Optionally, the fixing ring 2 has four upper connecting seats 1 corresponding to the four hydraulic rods distributed circumferentially, and the backpack frame 6 is provided with four lower connecting seats 13 corresponding to the four hydraulic rods at the shoulders and chest of the patient, two of which are located on both sides of the front end of the skull, and the other two are located on both sides of the rear end of the skull, and internal threaded holes are provided in the upper connecting seats 1 and the lower connecting seats 13, and the connecting rod 19 is an external threaded rod matching the internal threaded hole, and the external threaded rod is threadedly connected to the internal threaded hole. Specifically, four upper connecting seats 1 are evenly spaced around the fixed ring 2, and the upper connecting seats 1 are also made of medical stainless steel. Four lower connecting seats 13 corresponding to the upper connecting seats 1 are fixed on the shoulder and chest of the back frame 6. The upper connecting seats 1 and the lower connecting seats 13 are provided with internal threaded holes, and the connecting rod 19 is an external threaded rod. When installing the hydraulic rod, since the rotating seat 17 and the rotating ball 16 can rotate relative to each other, it is only necessary to screw the rotating seat 17 to thread the connecting rod 19 into the internal threaded hole, which is convenient for the installation and removal of the fixed ring 2. The fixed rings 2 of different sizes can be replaced according to the different skull sizes of patients. The operation is convenient and simple, and it is also convenient for the hydraulic rod to be removed from the back frame 6. In order to facilitate the screwing of the rotating seat 17, the rotating seat 17 can be processed into a hexagon or pentagon around the circumference, so that the rotating seat 17 can be screwed with tools such as a wrench.

Example 3

Optionally, the pressing device is an inflatable airbag 21, and the outer surface of the inflatable airbag 21 is an arc-shaped surface that matches the natural physiological curvature of the cervical spine.

In this embodiment, by designing the outer surface of the inflatable airbag 21 to be an arc-shaped surface, when the traction device is working, after the inflatable airbag 21 is inflated, the arc-shaped surface is completely fitted with the cervical spine, thereby effectively achieving lateral pressure on the cervical spine. Through the forces of the hydraulic cylinder and the inflatable airbag 21 in different directions, the cervical spine can restore its natural physiological curvature under the complementary action, effectively achieving the purpose of cervical correction.

The rubber airbag 27 has an inflation and deflation port, which can be used to inflate or deflate the rubber airbag 27. A plug is installed at the inflation and deflation port. When the fixing ring 2 is sleeved on the patient's head, since the head is not a complete circle, there will be a gap after the head is connected to the fixing ring 2. In order to enhance the fixing effect, the rubber airbag 27 can be inflated so that the rubber airbag 27 swells and fills the gap between the fixing ring 2 and the head, so that the fixing effect is better and the subsequent correction effect is also better. As shown in FIG7 , since the head size of each patient is different, in order to make the fixing ring 2 adapt to the heads of different patients, the fixing ring 2 is set to a size-variable structure. Specifically, the fixing ring 2 is composed of a left semicircular ring 201 and a right semicircular ring 202. The two semicircular rings are closed to form the fixing ring 2. A cylindrical sliding rod 28 is fixed to the right end of the left semicircular ring 201, and a sliding cavity 32 adapted to the sliding rod 28 is opened at the left end of the right semicircular ring 202.

A circular limiting ring 31 is fixed to the inner wall of the sliding cavity 32. The sliding rod 28 passes through The limiting ring 31 is then sleeved in the sliding cavity 32. The limiting ring 31 can prevent the sliding rod 28 from sliding out of the sliding cavity 32. A spring 30 is also provided in the sliding cavity 32. One end of the spring 30 acts on the limiting ring 31, and the other end acts on the baffle 29. When in use, the left semicircular ring 201 and the right semicircular ring 202 can be pulled apart from each other according to the size of the head of different patients. The baffle 29 moves to the left and squeezes the spring 30, thereby increasing the size of the ring formed by the two semicircular rings, which can be suitable for patients with larger heads. After the fixing ring 2 is sleeved on the head, the spring 30 is squeezed to generate a rightward elastic force in the opposite direction, so that the two semicircular rings can be firmly sleeved on the patient's head.
