Description

A fixator for treating muscular torticollis in children

Technical Field

The utility model relates to the technical field of medical treatment, in particular to a fixator for treating muscular torticollis in children.

Background technique

Torticollis in children, medically known as congenital muscular torticollis (commonly known as "crooked neck"), is caused by contracture of the sternocleidomastoid muscle fibers on one side, which causes it to shorten and the neck to deviate to one side. At the same time, facial development is affected, and the two sides of the face are of different sizes. In severe cases, it leads to scoliosis of the cervical spine. Therefore, people generally correct children with torticollis by using muscular torticollis fixators.

Some existing torticollis orthoses for children are installed together with a vest to ensure the stability of the orthosis, but they do not have the function of adjusting the distance between the orthosis and the vest. Since the distance between the shoulder and the neck of children of different heights and body shapes is different, the orthosis cannot be applied to children of different heights and body shapes, which has certain limitations.

Therefore, it is necessary to provide a new fixator for treating muscular torticollis in children to solve the above technical problems.

The fixator for treating muscular torticollis in children comprises: a vest 1. In order to make it convenient for the patient to wear the vest 1, two shoulder straps are fixedly installed on the vest 1. A fixing box 2 is fixedly installed on the outer wall of the vest 1. Two first rotating rods 3 are rotatably installed in the fixing box 2. The two first rotating rods 3 are respectively fixedly sleeved with slave gears 6. A second rotating rod 4 is rotatably installed in the fixing box 2. A moving gear 5 is fixedly sleeved on the second rotating rod 4, and the moving gear 5 is meshed with the two slave gears 6. A worm wheel 7 is fixedly sleeved on the second rotating rod 4. A worm 8 is rotatably installed in the fixing box 2. One end of the worm 8 extends outside the fixing box 2, and the worm 8 is meshed with the worm wheel 7. Since the worm wheel 7 and the worm 8 are self-locking, the tooth plate 10 can stably maintain the current position even under the action of external force to reduce the treatment correction of the patient. The fixing box 2, two tooth plates 10 are slidably installed on the upper part, and the two tooth plates 10 are respectively meshed with the corresponding slave gears 6. The tops of the two tooth plates 10 are respectively fixedly installed with connecting rods 13, and the tops of the two connecting rods 13 are fixedly installed with arc-shaped mandibular support plates 14, and the lower jaw of the child patient is supported by the arc-shaped mandibular support plate 14. Since the arc-shaped mandibular support plate 14 is arc-shaped, the head of the child patient cannot swing left and right on the arc-shaped mandibular support plate 14, and the muscular torticollis of the child patient is treated. An upper orthopedic ring plate 15 is arranged above the arc-shaped mandibular support plate 14, and an annular protective airbag 16 is installed in the upper orthopedic ring plate 15. An inflation tube is arranged on the annular protective airbag 16, and the annular protective airbag 16 is inflated and expanded by an external inflation device to contact the head of the child patient, so that the upper orthopedic ring plate 15 is firmly installed on the patient's head.

In order to make it more convenient for people to rotate the worm 8, a rotating handle 9 is fixedly installed on one end of the worm 8 outside the fixed box 2, and an anti-slip sleeve is fixed on the rotating handle 9 to prevent people from slipping when rotating the rotating handle 9, thereby affecting work efficiency.

In order to limit the tooth plate 10 and make the tooth plate 10 move more stably in the fixed box 2, a stabilizing plate 11 is fixedly installed at the bottom of the two tooth plates 10, and two limiting rods 12 are fixedly installed at the bottom of the fixed box 2, and the two limiting rods 12 respectively penetrate the two stabilizing plates 11 and are slidably connected to the two stabilizing plates 11. In order to reduce the friction between the limiting rod 12 and the stabilizing plate 11, thereby reducing the wear of the limiting rod 12 and increasing the service life of the limiting rod 12, two through holes are opened on the stabilizing plate 11, and linear bearings are fixedly installed in the two through holes, and the two limiting rods 12 respectively penetrate the two linear bearings and are slidably connected to the inner walls of the two linear bearings.

In order to connect the arc-shaped mandibular support plate 14 and the upper orthopedic ring plate 15 together, two Velcro straps 17 are fixedly installed on the arc-shaped mandibular support plate 14 , and the other ends of the two arc-shaped mandibular support plates 14 are fixedly connected to the upper orthopedic ring plate 15 .

The working principle of the fixator for treating muscular torticollis in children provided by the utility model is as follows: when people need to use the device, the staff wears the vest 1 on the child suffering from torticollis, firmly puts the vest 1 on the child patient through the straps, puts the upper orthopedic ring plate 15 on the head of the child patient, inflates the annular protective airbag 16 through the external inflation device, so that the annular protective airbag 16 expands and contacts the head of the child patient, firmly installs the upper orthopedic ring plate 15 on the head of the patient through the Velcro strap 17, supports the lower jaw of the child patient through the arc-shaped mandibular support plate 14, and the head of the child patient cannot swing left and right on the arc-shaped mandibular support plate 14 because the arc-shaped mandibular support plate 14 is arc-shaped, thereby completing the treatment of muscular torticollis of the child patient. When it is necessary to treat children of different heights and body shapes During the treatment of muscular torticollis, the medical staff rotates the rotating handle 9, which drives the worm 8 to rotate, which drives the worm gear 7 to rotate, which drives the second rotating rod 4 to rotate, which drives the moving gear 5 to rotate, which drives the two slave gears 6 to rotate, which drives the toothed plate 10 to move upward, which drives the connecting rod 13 to move upward, which drives the arc-shaped mandibular support plate 14 to move upward, thereby changing the distance between the vests 1 of the arc-shaped mandibular support plate 14, so that people can adjust the distance between the arc-shaped mandibular support plate 14 and the vest 1 according to the distance between the shoulder and neck of children of different heights and body shapes, thereby enabling the device to treat and correct children of different heights and body shapes, greatly improving the applicability of the device.

Compared with the related art, the fixator for treating muscular torticollis in children provided by the utility model has the following beneficial effects:

The utility model provides a fixator for treating muscular torticollis in children. A staff member wears a vest 1 on a child suffering from torticollis, and firmly puts the vest 1 on the child patient through a strap, puts an upper orthopedic ring plate 15 on the child patient's head, inflates an annular protective airbag 16 through an external inflation device to make it contact with the child patient's head, firmly mounts the upper orthopedic ring plate 15 on the patient's head through a Velcro strap 17, and supports the child patient's lower jaw through an arc-shaped mandibular support plate 14. Since the arc-shaped mandibular support plate 14 is arc-shaped, the child patient's The head cannot shake left and right on the arc-shaped mandibular support plate 14, so the muscular torticollis of the child patient is treated. When it is necessary to treat muscular torticollis for children of different heights and body shapes, the arc-shaped mandibular support plate 14 is driven to move upward by rotating the handle 9, and then the distance between the vests 1 of the arc-shaped mandibular support plate 14 is changed, so that people can adjust the distance between the arc-shaped mandibular support plate 14 and the vest 1 according to the distance between the shoulder and neck of children of different heights and body shapes, so that the device can treat and correct children of different heights and body shapes, thereby greatly improving the applicability of the device.
