Description

Technical Field

[0001] The invention relates to a cervical collar for rehabilitation training after thyroid surgery. Background Art

[0002] Millions of people around the world suffer from thyroid diseases, such as an enlarged goiter, noncancerous or cancerous thyroid nodules, or an overactive thyroid gland. Some thyroid diseases can be treated with medication, but other conditions are best treated with surgery. After thyroid surgery, functional exercises for the neck are required. Patients who have undergone thyroid lobe, subtotal thyroidectomy, and total thyroidectomy should begin neck functional exercises in a gradual manner on the first day after surgery if they have no discomfort. Specific movements include relaxing the shoulders and neck, looking down, turning the face left and right, and tilting the head left and right.

[0003] For example, the Chinese invention patent with publication number CN114191782B provides a cervical activity assistance and rehabilitation training orthosis after total thyroidectomy, which includes a switchable front support part, a detachable rear resistance part, and a control component that provides variable damping. When in use, the device can switch between static and active states at will. The variable damping device in the control component can provide resistance that changes linearly with the angle for stretching movements, so as to strengthen the output of the extensor muscles while weakening the output of the flexor muscles, and assist patients in active rehabilitation training.

[0051] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0052] Example:

[0053] like Figure 1 As shown, the present invention provides a cervical collar for postoperative rehabilitation training of thyroid surgery, including a fixator 101, on which a cervical collar main body 103 connected by an elastic band 102 is arranged. When in use, the fixator 101 can be fixed to the patient's shoulder by a strap, and the cervical collar main body 103 can be sleeved on the patient's neck, and the cervical collar main body 103 can also be fixedly connected to the patient's head by a strap to support the patient's neck. In the process of moving the patient's neck, the cervical collar main body 103 can be driven to move, and the elastic band 102 can stretch and deform following the movement of the cervical collar main body 103.

[0054] like Figures 1 to 3 , Figure 7As shown, in this embodiment, a slide rail 104 is provided on the collar body 103, and connecting blocks 105 are slidably provided at both ends of the slide rail 104, and a slider 301 is slidably provided in the middle area of ​​the slide rail 104. Two groups of resistance components are provided on the collar body 103, and resistance is applied to the sliding of the two groups of connecting blocks 105 through the resistance components. The resistance components include two groups of sliding seats 106, and the two groups of sliding seats 106 are slidably provided at both ends of the slide rail 104, respectively, and the connecting block 105 is located on the side of the sliding seat 106 away from the slider 301. The sliding seat 106 and the end of the slide rail 104 are connected by a tension spring 107. An adjusting mechanism is provided on the fixing device 101, and an adjustable resistance is applied to the sliding of the two sets of sliders 301 through the adjusting mechanism. The adjusting mechanism includes a mounting frame 201 provided on the fixing device 101, and a rotatable tensioning wheel 202 is provided in the mounting frame 201. A pull rope 208 is wound around the tensioning wheel 202, and both ends of the pull rope 208 are respectively connected to the two sets of connecting blocks 105.

[0055] In the process of turning the head left and right, the movement of the head drives the neck support body 103 to follow the movement. In the process of the neck support body 103 moving in the above direction, the sum of the distances between the two groups of connection blocks 105 and the tensioning wheel 202 is the minimum in the initial state. When the head moves, the distances between the two groups of connection blocks 105 and the tensioning wheel 202 change, so that the connection blocks 105 slide on the slide rail 104, and one group of connection blocks 105 pushes the sliding seat 106 to stretch the tension spring 107 on one side, thereby applying resistance to the movement of the neck swinging left and right and turning the head, achieving the exercise effect. When performing the head-down action, both groups of connection blocks 105 slide along the slide rail 104, thereby applying resistance to the head-down movement.

[0056] like Figures 2 to 4 , Figure 7 , Figure 8 As shown, in this embodiment, the adjustment mechanism further includes a pressure assembly arranged on the mounting frame 201, and the resistance to the rotation of the tensioning wheel 202 is adjusted by the pressure assembly. The pressure assembly includes a pressure plate 204 slidably arranged in the mounting frame 201 along its axis, a first friction plate 203 is arranged on one side of the tensioning wheel 202, a second friction plate 205 is arranged on one side of the pressure plate 204, the first friction plate 203 abuts against the second friction plate 205, a threaded knob 207 is screwed on the mounting frame 201, an elastic member 206 is arranged at the end of the threaded knob 207, and the elastic member 206 abuts against the pressure plate 204.

[0057] In the process of swinging and turning the head left and right, the tensioning wheel 202 is driven to rotate by the pull rope 208. During the rotation of the tensioning wheel 202, the first friction plate 203 and the second friction plate 205 cooperate to apply resistance to the movement of the tensioning wheel 202, and the elastic member 206 can be compressed by rotating the threaded knob 207, so as to adjust the friction force of the tensioning wheel 202, so as to achieve the purpose of adjusting the training resistance, and to achieve exercise in multiple directions. In addition, multiple groups of clamping teeth are evenly distributed in the circumferential direction on the outer circumferential surface of the tensioning wheel 202, and multiple groups of clamping blocks 209 are arranged at intervals on the pull rope 208. The clamping blocks 209 are clamped in the gaps between the multiple groups of clamping teeth. Through the cooperation of the clamping blocks 209 and the clamping teeth, the tensioning wheel 202 can be stably controlled to rotate when the pull rope 208 moves, so as to improve the stability of the training.

[0058] like Figure 4 , 6 As shown, in this embodiment, the fixture 101 is provided with a connecting tube 305 connected by a spherical joint assembly, and the slider 301 is slidably sleeved on the connecting tube 305. The spherical joint assembly includes a spherical shell 302 provided on the fixture 101, and a connecting ball 304 is provided at the bottom of the connecting tube 305, and the connecting ball 304 is movably clamped in the spherical shell 302. During the swinging and lowering of the neck support body 103, the connecting ball 304 can move in the spherical shell 302, and the connecting ball 304 is the fulcrum of the neck support body 103, and the slider 301 can slide on the connecting tube 305 to adapt to the position deviation of the neck support body 103.

[0059] like Figures 4 to 6As shown, in this embodiment, a locking mechanism is provided on the connecting tube 305, and the relative positions of the neck support body 103, the slider 301 and the fixer 101 are fixed by the locking mechanism. The locking mechanism includes a threaded column 306 threaded on the connecting tube 305, and a first locking assembly connected to the spherical shell 302 is provided on the threaded column 306. The position of the connecting ball 304 in the spherical shell 302 can be selectively locked or unlocked by the first locking assembly during the rotation of the threaded column 306. The first locking assembly includes a fixing column 307 provided at the bottom, and a fixing hole 303 is provided in the spherical shell 302. When the center line of the connecting tube 305 and the fixer 101 are parallel, the axis of the fixing column 307 coincides with the axis of the fixing hole 303. A second locking assembly is also provided on the threaded column 306 and connected to the neck support body 103. The position of the neck support body 103 can be selectively locked or unlocked by the second locking assembly during the rotation of the threaded column 306. The second locking assembly includes a connecting frame 308, one end of the connecting frame 308 is rotatably mounted on the connecting frame 308, and the other end is provided with a locking block. A slot 108 is provided on the neck support body 103, and the locking block can be clamped in the slot 108. Two groups of parallel guide plates 309 are provided on the slider 301, and the connecting frame 308 is movably clamped between the two groups of guide plates 309.

[0060] When no training is needed, the patient is asked to straighten his head and rotate the threaded column 306 to make it slide along the axis of the connecting tube 305. During the movement of the threaded column 306, the fixing column 307 is driven to move downward and penetrate into the fixing hole 303 to fix the position of the connecting ball 304 in the spherical shell 302, so that the neck support body 103 cannot swing or lower the head. During the movement of the threaded column 306, the connecting frame 308 is driven to move downward, and the movement of the connecting frame 308 is positioned by the guide plate 309, so that the locking block at the end of the connecting frame 308 is clamped into the card slot 108 to fix the relative position of the neck support body 103 and the slider 301, so that the relative positions of the neck support body 103, the slider 301 and the fixer 101 are fixed to provide stable support for the patient's neck.

[0061] Specific usage and beneficial effects of the present invention:

[0062] When the rehabilitation training neck brace is in use, the fixator 101 is fixed to the patient's shoulder by a strap, and the neck brace body 103 is sleeved on the patient's neck. When the patient uses it, the neck brace body 103 can be driven to move by swinging the head left and right, rotating the neck, and lowering the head. In the process of turning the head left and right, the slider 301 slides on the slide rail 104, and resistance is applied to the movement of one group of connecting blocks 105 through one group of resistance components, so as to exercise the neck movement. In the process of swinging the head left and right, the resistance of the neck brace body 103 is applied by the adjustment mechanism, and the resistance is adjustable under the action of the adjustment mechanism to adapt to the patient's condition. It can be used by different patients. During the head-lowering exercise, the two groups of connecting blocks 105 slide on the slide rail 104. The two groups of resistance components apply resistance to the movement of the two groups of connecting blocks 105 to train the head-lowering exercise, so that the rehabilitation training neck brace can adjust the multi-directional movement of the neck. After the training is completed, the relative positions of the neck brace body 103, the slider 301 and the fixer 101 can be quickly fixed through the locking mechanism to support the patient's neck. Compared with the traditional rehabilitation training neck brace, it has a wider range of applications and more comprehensive training, which effectively improves the efficiency of postoperative rehabilitation.
