Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of traction device equipment, and in particular relates to an adjustable cervical vertebra traction device. Background Art
[0002] The normal cervical spine maintains a physiological lordosis with an average of 14.4°. Any degree of reversal of the cervical lordosis is called cervical kyphosis. Cervical kyphosis can be seen in adults and children, but is more common in adolescent patients. A variety of factors can cause cervical kyphosis, including congenital developmental deformities of the cervical spine (such as incomplete vertebral separation, vertebral dysplasia, etc.), iatrogenic cervical kyphosis (such as post-radiation developmental deformity, kyphosis caused by posterior laminectomy), and trauma, degeneration, infection, tumors and other factors can all cause cervical kyphosis. After the cervical kyphosis, the cervical cord and nerve roots are compressed and stretched, pathological damage may occur, and then clinical symptoms appear, which often require surgical treatment. Cervical suspension traction pre-correction plays an important role in the treatment of cervical kyphosis.
[0003] The suspension traction designed and used by the Third Hospital of Peking University has achieved good results in the correction of cervical kyphosis. The traction belt relies on the weight of the patient's head to perform vertical suspension traction to correct kyphosis. Due to the different lengths of children's and adults' necks, the severity of kyphosis, and the different forces at the apex and proximal and distal ends of the kyphosis at the beginning and after traction, the traction belt cannot fully exert the effect of vertical suspension traction.

Through the adjustable setting, the traction operation of different patients can be satisfied, and the stress concentration during traction can be avoided, which may cause the patient to be unable to withstand the traction. When the kyphosis becomes smaller during the traction process, the stress can be increased by adding an inelastic traction rope at the vertex to improve the traction effect.

[0035] Reference Figure 3, the traction rope group 6 is connected and set by setting a traction hook 1 with adjustable length, so that the installation length of the adhesive pad 9 can be controlled and adjusted, thereby achieving high-matching traction for the cervical vertebrae of different patients; more specifically, since the main rod 2 and the auxiliary rod 3 are set in the traction hook 1, the auxiliary rod 3 is slidably set in the main rod 2, and can be relatively locked and fixed in the main rod 2. Adjustment, and then the total length of multiple auxiliary hooks 5 installed on the traction hook 1 can be set, thereby achieving the installation of adhesive pads 9 of different lengths, thereby meeting the needs of traction settings for the cervical vertebrae of different patients and improving the effect of traction operation on patients.
[0036] Preferably, the main rod 2 is a hollow structure, and one auxiliary rod 3 is respectively provided at both ends of the main rod 2 , and one side of the auxiliary rod 3 is fixed relative to the main rod 2 by a bolt 10 provided on one side of the main rod 2 .
[0037] It can be understood that the main rod 2 is set as a hollow structure, which provides space for the auxiliary rod 3 to slide relatively inside the main rod 2. At the same time, a bolt 10 is set on one side of the main rod 2, and the bolt 10 is screwed in and out relative to the main rod 2, so as to achieve a relatively fixed setting of the auxiliary rod 3 after relative sliding adjustment inside the main rod 2, thereby realizing the adjustment setting of the length of the entire traction hook 1.
[0038] Preferably, a main slide groove 11 is provided on the side of the main rod 2 opposite to the bolt 10, and a secondary slide groove 12 is provided on the same side of the secondary rod 3 as the main slide groove 11, and the main slide groove 11 and the secondary slide groove 12 are arranged in communication on the same plane; the main slide groove 11 and the secondary slide groove 12 form a secondary hook adjustment groove 13, and a plurality of secondary hooks 5 are arranged in the secondary hook adjustment groove 13.

Elastic traction ropes are used at the distal and proximal ends of the kyphosis apex. According to the different degrees of force on the patient, the extension of the traction rope is different, so as to avoid excessive concentration of stress during traction, which makes the patient unable to withstand traction. When the kyphosis becomes smaller during traction, the stress can be increased by adding an inelastic traction rope at the apex to improve the traction effect.

[0049] The working principle and working process of this utility model:
[0050] When an adjustable cervical traction device provided in the utility model is used, after adjusting the length of the two traction hooks, the two main hooks are suspended, so that the traction rope group between the two main hooks is fixedly set to the adhesive pad of the corresponding length, and the traction rope group 6 is connected and set by setting the traction hook 1 with adjustable length, so that the installation length of the adhesive pad 9 is controlled and adjusted, thereby realizing high-matching traction of the cervical vertebrae of different patients; more specifically, since the main rod 2 and the auxiliary rod 3 are set in the traction hook 1, the auxiliary rod 3 is slidably set in the main rod 2, and can be relatively locked and fixed in the main rod 2.

[0051] Furthermore, since more than two end elastic ropes 7 and more than two fixed inelastic ropes 8 are arranged between the two traction hooks 1, a better relative arrangement and installation of the adhesive pad 9 with a certain length and width is achieved, and the adhesive pad 9 is arranged in the middle of the traction rope group 6, which is beneficial to the traction of the patient; during traction, the inelastic traction rope is placed at the apex of the posterior kyphosis, and the force is maximum during vertical suspension traction. Elastic traction ropes are used at the distal and proximal ends of the apex of the posterior kyphosis. The extension of the traction rope is different according to the different degree of force on the patient, so as to avoid excessive concentration of stress during traction, which may cause the patient to be unable to withstand traction. In addition, when the kyphosis becomes smaller during traction, the stress can be increased by adding an inelastic traction rope at the apex to improve the traction effect.
