Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an elastic adjustable cervical traction device. Background Technology

[0002] Cervical traction is a physical therapy in clinical medicine that uses external force to stretch the cervical spine joints to treat cervical spine diseases. Based on the principle of action and reaction, it stretches soft tissues, relieves nerve compression, and improves the intervertebral space. There are two traction methods: sitting or lying intermittent traction. While sitting intermittent traction is convenient, patients' neck muscles are not easily relaxed, leading to poor traction effects. Therefore, currently, lying intermittent traction is commonly used for cervical spine traction. Traditional lying traction devices typically consist of a fixed part attached to the bed, a traction rope and its support, and a gravity-operated device. During use, medical staff need to assemble these parts, which is time-consuming and labor-intensive. Furthermore, traction is performed by gravity, making it difficult to precisely control the traction force and direction. It is also a static gravity traction method, resulting in limited traction options and poor therapeutic effects. Currently, some traction devices replace traditional traction equipment, but most are dedicated traction beds with complex structures and large sizes, unsuitable for home use. Therefore, there is an urgent need for a simple, quick-installation, precisely adjustable, and dynamically traction-enabled cervical traction device to meet clinical or daily needs. Summary of the Invention

[0003] The present invention aims to provide an elastic adjustable cervical traction device to solve the problems of cumbersome assembly, inability to accurately adjust and provide dynamic traction in current traction devices.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An elastic adjustable cervical traction device includes a fixed plate, an electric slide, an adjustment unit, and two sets of auxiliary rods. The fixed plate is equipped with a control terminal for controlling the operation of various electrical components. The electric slide is mounted on the fixed plate to drive the adjustment unit to move longitudinally. The auxiliary rods are located on both sides of the fixed plate to press against the patient's shoulders. A sliding platform and a sliding part, as well as a drive group for driving the sliding part, are respectively arranged in the cavity of the adjustment unit. A tension spring for providing tension is connected between the sliding platform and the sliding part. A sliding groove is opened on the sliding platform, and a sliding block and a drive group for driving the sliding block to move laterally are slidably arranged in the sliding groove. A tension sensor and a displacement sensor are integrated in the sliding block. The tension sensor is connected to one end of a pull rope, and the other end of the pull rope is connected to a crossbar. The crossbar is used to connect the patient's occipital band.

[0006] Furthermore, one end of the auxiliary rod is hinged to the moving block, the moving block is slidably set in the limiting groove on the fixed plate, the other end of the auxiliary rod is provided with a telescopic rod and a locking bolt for locking the telescopic rod, and the end of the telescopic rod is provided with a shoulder plate for abutting against the patient's shoulder.

[0007] Furthermore, a stop button is provided on one side of the shoulder plate, which is electrically connected to the control terminal for emergency traction stop. A soft pad is provided on the other side of the shoulder plate, and both the soft pad and the shoulder plate are curved.

[0008] Furthermore, an insert plate is slidably arranged inside the fixed plate, and two sets of rotating columns are arranged inside the insert plate. A base plate is provided at the bottom end of the rotating column, and the base plate is located at the bottom edge of the insert plate. A handle is provided on the insert plate, and the handle is located on the surface of the fixed plate. A drive rod is rotatably arranged inside the fixed plate, with the bottom end of the drive rod passing through the rotating column and the top end of the drive rod extending out of the top edge of the fixed plate.

[0009] Furthermore, an indicator rod is provided on the moving part, which extends out of the adjusting part and corresponds to the position of the scale line on the surface of the adjusting part. The scale line corresponds to the magnitude of the elastic force of the tension spring.

[0010] Furthermore, a fixing hook is provided on the top of the fixing plate, which is used to hang the fixing plate on the endboard of the hospital bed, and a fixing bolt is provided on the fixing hook.

[0011] Furthermore, the fixed plate is equipped with a placement box and two sets of elastic clamps. The placement box is used to store the control terminal, and the elastic clamps are used to hold the crossbar.

[0012] Furthermore, two sets of rollers are arranged opposite each other on the sliding block, and the two sets of rollers are located on both sides of the pull rope to limit the position of the pull rope.

[0013] The principles and beneficial effects of the technical solution are as follows:

[0014] This invention provides an elastic adjustable cervical traction device. The fixing plate can be quickly hung at the foot of the bed. Assembly is completed quickly by using an auxiliary rod to support the patient's shoulder and a chin strap to hook onto the patient's jaw with a crossbar. The operation is simple and requires no individual assembly of the device's components. The longitudinal angle of the traction rope can be changed by moving the electric slide, thus precisely adjusting the flexion angle of the traction. The drive unit moves the moving part downwards, causing the tension spring to deform and tighten the moving platform, giving it a downward tendency, thereby tightening the traction rope. Adjusting the length of the tension spring by the moving part provides different levels of traction force, and precise force adjustment is achieved with the help of a tension sensor. The drive unit drives the sliding block to slowly reciprocate within the moving platform, changing the lateral angle of the traction rope, causing slight lateral flexion of the patient's neck, mimicking joint mobilization techniques performed by medical personnel, achieving dynamic traction and improving the effectiveness of traction therapy.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0022] like Figures 1-5As shown, an elastic adjustable cervical traction device includes a fixed plate 1, an electric slide 103, an adjustment unit 2, and two sets of auxiliary rods 3. The fixed plate 1 is equipped with a control terminal 4 for controlling the operation of various electrical components. Medical personnel can set the traction force and angle through the control terminal 4, which in turn controls the electric slide 103 and other electrical components such as the drive unit to perform corresponding actions. The electric slide 103 is mounted on the fixed plate 1 to drive the adjustment unit 2 to move longitudinally. The electric slide 103 can be a linear guide slide from the prior art, enabling high-precision displacement control. The system allows for precise control of the longitudinal angle of traction. Auxiliary rods 3 are positioned on both sides of the fixed plate 1 to press against the patient's shoulders. These rods, in conjunction with the chin strap fixing the patient's jaw, form a neck brace structure for fixation, preventing the patient from moving unnecessarily and affecting the traction effect. The cavity within the adjustment unit 2 contains a sliding platform 203, a moving part 204, and a drive assembly for moving the moving part 204. A tension spring 205 connects the platform 203 and the moving part 204 to provide tension. The platform 203 has a... The slide groove 207 contains a sliding block 206 and a drive assembly for lateral movement of the sliding block 206. The drive assembly can be a ball screw or other structure capable of moving the moving part 204 and the sliding block 206, as is available in the prior art. This allows for adjustment of the length of the tension spring 205 and the position of the sliding block 206, thus achieving high-precision adjustment of the traction force and lateral traction angle. The sliding block 206 integrates a tension sensor 208 and a displacement sensor 209, and the information collected by each sensor is fed back to the control terminal 4. The control terminal 4 controls the action of the drive group. The tension sensor 208 and the displacement sensor 209 are both sensor types used in the prior art. They are used to monitor the tension value of the pull rope 201 to determine the traction force, and to monitor the displacement distance and speed of the sliding block 206, thereby assisting the control terminal 4 in controlling the reciprocating lateral flexion traction amplitude of the device. The tension sensor 208 is connected to one end of the pull rope 201, and the other end of the pull rope 201 is connected to the crossbar 202. The crossbar 202 is used to connect the occipital-mandibular band of the patient's mandible. The occipital-mandibular band is a commonly used device in clinical traction therapy.

[0023] In use, firstly, the patient lies on the bed. Medical staff attach the fixation plate 1 to the baffle at the foot of the bed, rotate the auxiliary rod 3 to make it perpendicular to the fixation plate 1, and then move the patient so that the auxiliary rod 3 rests against the patient's shoulder, restricting the patient's position. The chin strap is then fixed to the back of the patient's neck and chin, and finally connected to the crossbar 202. The entire operation is simple; the various components of the traction device are integrated, replacing traditional traction equipment, eliminating the need for assembly and reducing the burden on medical staff. Furthermore, the entire device is small in size and simple in structure, suitable for home use. After assembly, medical staff control... The control terminal 4 sets the traction force and traction angle. After setting, the control terminal 4 controls the electric slide 103 to move on the guide rail, changing the height of the adjustment unit 2, thereby changing the longitudinal traction angle of the pull rope 201, so that the patient's cervical spine is tractioned in a suitable forward flexion, replacing the rough height adjustment of traditional traction devices; at the same time, the drive unit drives the moving part 204 to move downward, stretching the tension spring 205. After the tension spring 205 is stretched, the elastic force it provides increases, giving the moving platform 203 a downward tendency, so that the moving platform 203 tightens the pull rope 201 through the sliding block 206, and the pull rope... 201 tightens the occipital-chin strap to apply traction to the patient's cervical spine. The tension sensor 208 at the end of the rope 201 monitors the tension to determine the magnitude of the traction force. This determines the downward movement of the moving part 204, which extends the tension spring 205, allowing for precise traction force assessment and adjustment. Compared to traditional gravity traction using a weight, this method offers more precise and controllable traction. Simultaneously, the drive unit on the moving platform 203 controls the movement of the sliding block 206 within the groove 207, altering its position and deviating it from the axis of the patient's cervical spine. This movement is monitored by a displacement sensor. 209 monitors the displacement distance of the sliding block 206 to make precise adjustments to the lateral traction angle. After adjustment, all components remain stationary for static traction. Alternatively, depending on the patient's actual condition, the traction force can be adjusted, and the electric slide 103 can be slowly moved back and forth via the control terminal 4 to change the longitudinal angle of the pull rope 201 for dynamic traction of cervical flexion and extension. Or, the drive group can be controlled to make the sliding block 206 slowly move back and forth laterally to change the lateral angle of the pull rope 201, thereby performing dynamic traction of lateral flexion of the cervical spine. This allows the device to perform traction in multiple ways, resulting in better performance.

[0024] In this embodiment, one end of the auxiliary rod 3 is hinged to the movable block 107. The movable block 107 is slidably disposed in the limiting groove 106 on the fixed plate 1. A damping ring is provided between the movable block 107 and the smooth rod in the limiting groove 106, so that there is a certain damping between the two when the movable block 107 slides, and it will not move arbitrarily. The other end of the auxiliary rod 3 is provided with a telescopic rod 301 and a locking bolt 304 for locking the telescopic rod 301. The end of the telescopic rod 301 is provided with a shoulder plate 302 for abutting against the patient's shoulder. By moving the movable block 107 in the limiting groove 106, the distance between the two sets of auxiliary rods 3 can be adjusted, thereby adapting to patients with different head circumferences. Extending the telescopic rod 301 out of the auxiliary rod 3 and locking it with the locking bolt 304 can adjust the overall length of the auxiliary rod 3. Then, the shoulder plate 302 can more conveniently abut against the patient's shoulder. At the same time, after shrinking, the volume is smaller and easier to store.

[0025] In this embodiment, a stop button is provided on one side of the shoulder plate 302. The stop button is electrically connected to the control terminal 4 for emergency traction cessation. A soft pad 303 is provided on the other side of the shoulder plate 302. Both the soft pad 303 and the shoulder plate 302 are arc-shaped. The arc-shaped shoulder plate 302 and soft pad 303 can better fit the patient's shoulder, and the soft pad 303 is made of flexible material, which can improve the comfort of use. After the shoulder plate 302 rests against the patient's shoulder, the stop button is also located at the patient's shoulder position, so that the patient can reach the stop button himself. When the patient feels uncomfortable or needs to stop treatment, he only needs to press the stop button, which will enable the control terminal 4 to control the entire device to stop traction. This allows the patient to control the device independently without relying entirely on medical staff, avoiding situations where medical staff are not in the ward and cannot stop the traction in time, effectively improving the safety of the device.

[0026] In this embodiment, a sliding insert plate 5 is provided inside the fixed plate 1. Two sets of rotating columns 501 are provided inside the insert plate 5. A base plate 502 is provided at the bottom end of the rotating column 501. The base plate 502 is located at the bottom edge of the insert plate 5. A handle 504 is provided on the insert plate 5. The handle 504 is located on the surface of the fixed plate 1. A drive rod 503 is rotatably provided inside the fixed plate 1. The bottom end of the drive rod 503 passes through the rotating column 501. When the insert plate 5 drives the rotating column 501 to move downward, the rotating column 501 moves relative to the drive rod 503, but does not separate from the drive rod 503. The top end of the drive rod 503 extends out of the top edge of the fixed plate 1. When used at home, home beds typically do not have a footboard. Users simply need to push the handle 504 to move the insert plate 5, causing it to extend beyond the bottom edge of the fixing plate 1. Insert the insert plate 5 into the gap between the bed frame and the mattress at the head of the bed. Then, rotate the drive rod 503, which drives the rotating column 501 to rotate through the hexagonal column at its bottom. This rotates the base plate 502 so that it is perpendicular to the surface of the insert plate 5, thus locking it under the mattress. This improves the stability of the fixation and allows the fixing plate 1 to be securely fixed at the head of the bed, making it convenient for patients to use at home.

[0027] In this embodiment, an indicator rod 211 is provided on the moving part 204. The indicator rod 211 extends out of the adjusting part 2 and corresponds to the position of the scale line 105 on the surface of the adjusting part 2. The scale line 105 corresponds to the magnitude of the elastic force of the tension spring 205. After the traction force is set at the control end 4, the drive unit drives the moving part 204 to move. At the same time, the indicator rod 211 moves synchronously with the moving part 204, indicating the value on the scale line 105 on the surface of the adjusting part 2. This provides a more intuitive indication of whether the traction force has been adjusted to the correct level, making it convenient for medical personnel to observe.

[0028] In this embodiment, a fixing hook 101 is provided on the top of the fixing plate 1. The fixing hook 101 is used to hang the fixing plate 1 on the end panel of the hospital bed. A fixing bolt 102 is provided on the fixing hook 101. The fixing hook 101 has a certain width, which can increase the stability of the hanging. At the same time, after hanging, by tightening the fixing bolt 102, the fixing hook 101 can be securely locked to the end panel of the hospital bed, replacing the traditional simple hook and improving the stability of the installation.

[0029] In this embodiment, the fixing plate 1 is provided with a storage box 401 and two sets of elastic clips 104. The storage box 401 is used to store the control terminal 4, and the elastic clips 104 are used to hold the crossbar 202. After use, the control terminal 4 can be stored in the storage box 401, and the crossbar 202 can be clamped and fixed to the top of the fixing plate 1 by the elastic clips 104. The components of the device can be stored with a simple structure, making the device more compact and convenient to store.

[0030] In this embodiment, two sets of rollers 210 are arranged opposite each other on the sliding block 206. The two sets of rollers 210 are located on both sides of the pull rope 201 and are used to limit the position of the pull rope 201. The rollers 210 can reduce the friction of the pull rope 201 and prevent the pull rope 201 from directly rubbing against the edge of the sliding block 206, which would cause excessive wear and damage to the pull rope 201.
