Description

Technical Field

[0001] This utility model is specifically a neck traction fixation device. Background Technology

[0002] A cervical collar is an auxiliary treatment device for cervical spondylosis. It can immobilize and protect the cervical spine, reduce nerve wear, alleviate traumatic reactions of the intervertebral joints, and help reduce tissue edema, consolidate therapeutic effects, and prevent recurrence. Office workers today face high work pressure, and overtime work further exacerbates the burden on the cervical spine. The widespread use of smartphones also increases the burden on the cervical spine, making it more susceptible to cervical spondylosis.

[0003] While existing neck braces offer overall height adjustment, they are not ideal for patients with torticollis, especially children. In the initial stages of treatment, they cannot individually adjust the height of the left, right, and back sides of the neck. This results in discomfort and poor corrective effects, as they fail to provide effective fixation and support for the left, right, and back sides of the neck, and are ineffective in stretching and correcting the neck muscles at different locations. Utility Model Content

[0004] In view of the above, this utility model provides a neck traction fixation device to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A neck traction and fixation device is provided, including an elastic support part with a neck support function. The elastic support part is provided with an adjustment component for adjusting and stretching the neck muscles. The adjustment component includes a shell, an upper support frame, a lower support frame, a transmission component, and a rotation adjustment part. The shell is hollow inside. The upper support frame and the lower support frame are respectively staggered inside the shell. The transmission component is engaged between the upper support frame and the lower support frame. The rotation adjustment part is provided on the shell and connected to the transmission end of the transmission component. The rotation adjustment part includes an adjustment plate and a rotating cover. The front of the shell has a mounting groove. The inner edge of the mounting groove has a rigid toothed surface. The outer wall of the adjustment plate has two concave notches that cooperate with the rigid toothed surface. The adjustment plate is fitted into the mounting groove. The rotating cover is fitted onto the adjustment plate through a fixing hole. In use, the rotating cover is manually adjusted, which drives the transmission component to move through the adjustment plate, so that the upper support frame and the lower support frame slide up and down relative to each other inside the shell to adjust and stretch the elastic support part.

[0006] Furthermore, both the outer ends of the upper and lower support frames are provided with engaging grooves, and the side of the elastic support part is provided with a hollow groove, with slides that cooperate with the engaging grooves on the upper and lower inner sides of the hollow groove.

[0007] Furthermore, there are at least two adjustment components, both of which can move within the hollowed-out slot.

[0008] Furthermore, the elastic support part has an opening for fitting around the neck, and the two sides of the opening are connected by a fixing sleeve, so that the elastic support part forms a column shape similar to the contour of the neck, and the fit between the elastic support part and the neck can be adjusted by adjusting the fastening length of the fixing sleeve.

[0009] Furthermore, the elastic support is a one-piece structural design.

[0010] Furthermore, a right rack is provided on the right side of the upper support frame, and a left rack is provided on the left side of the lower support frame. The right rack and the left rack are arranged alternately inside the outer shell.

[0011] Furthermore, the transmission assembly includes an upper gear that meshes with the right rack, a main transmission gear, and a lower gear that meshes with the left rack, with the main transmission gear meshing between the upper gear and the lower gear.

[0012] Furthermore, the tooth width of the main drive gear is greater than the tooth width of the upper gear and the lower gear. The lower tooth width of the main drive gear meshes with the upper gear, and the upper tooth width of the main drive gear meshes with the lower gear.

[0013] Furthermore, the adjusting plate is connected to the main drive gear.

[0014] Furthermore, a cover is provided on the back of the outer casing, and matching fixing holes are provided on the cover, the main drive gear, the adjusting plate and the rotating cover, and connecting threads are provided in the fixing holes of the rotating cover.

[0015] The cervical traction fixation device of this utility model, by setting an elastic support part, is used to protect the cervical spine, reduce nerve wear, and alleviate traumatic reactions of the intervertebral joints.

[0016] By setting multiple adjustable components that move independently inside the elastic support, the elastic support can provide individual traction and fixation to the left, right, and back of the neck. Especially for patients with torticollis, it can stretch the neck muscles at different positions of the neck, relieve neck muscle tension, and make the torticollis correction effect more significant. It can meet the needs of not only ordinary neck brace wearers but also torticollis wearers. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and some embodiments.

[0029] exist Figures 1-10A cervical traction and fixation device is provided, including an elastic support part 1 with a cervical support function. The elastic support part 1 is provided with an adjustment component 2 for adjusting the height and stretching of the cervical muscles. The adjustment component 2 includes a housing, an upper support frame 3, a lower support frame 5, a transmission component, and a rotation adjustment part. The housing is hollow, and the upper support frame 3 and lower support frame 5 are respectively staggered and arranged vertically inside the housing. The transmission component is engaged between the upper support frame 3 and lower support frame 5. The elastic support part 1 has a fitting for... The opening in the neck is connected on both sides by a fixing sleeve 102, so that the elastic support part 1 forms a column shape similar to the contour of the neck. The fit between the elastic support part 1 and the neck can be adjusted by adjusting the fastening length of the fixing sleeve 102. The fit between the elastic support part 1 and the neck can be adjusted by manually adjusting the fastening length of the fixing sleeve 102 to make it fit the neck better, so as to protect the cervical spine, reduce nerve wear, and reduce traumatic reactions of the intervertebral joints. In actual production, the elastic support part 1 can be made of rubber, foam plastic, high elastic fiber composite material, etc.

[0030] In this embodiment, the rotation adjustment part is disposed on the outer shell and connected to the transmission end of the transmission assembly. The rotation adjustment part includes an adjustment plate 11 and a rotating cover 14. The front of the outer shell has a mounting groove 10, and the inner edge of the mounting groove 10 has a rigid toothed surface 16. The outer wall of the adjustment plate 11 has two concave notches 15 that mate with the rigid toothed surface 16. The adjustment plate 11 is fitted into the mounting groove 10. The rotating cover 14 is mounted on the adjustment plate 11 through fixing holes 12. The right side of the upper support frame 3 is provided with... A right rack 301 and a left rack 501 are provided on the left side of the lower support frame 5. The right rack 301 and the left rack 501 are arranged alternately inside the outer shell. The transmission assembly includes an upper gear 6 that meshes with the right rack 301, a main transmission gear 8, and a lower gear 7 that meshes with the left rack 501. The main transmission gear 8 is meshed between the upper gear 6 and the lower gear 7. The adjusting plate 11 is connected to the main transmission gear 8. The elastic support part 1 is fitted around the neck of the patient or user. The rotating cover 14 can be manually adjusted clockwise. This causes the main drive gear 8 on the adjusting plate 11 to rotate clockwise. The main drive gear 8 engages with the upper gear 6 and the lower gear 7 respectively. During the transmission process, the upper gear 6 and the lower gear 7 engage with the right rack 301 and the left rack 501 respectively, causing the upper support frame 3 and the lower support frame 5 to slide upward and downward toward the outside of the outer shell respectively, thereby raising the elastic support part 1, increasing the stretching of the neck muscles, and relieving neck muscle tension. Manually rotating the cover 14 counterclockwise overcomes the rigid toothed surface 16 of the inner edge of the mounting groove 10 and the concave notch. The resistance between 15 causes the main drive gear 8 on the adjusting plate 11 to rotate counterclockwise, causing the upper support frame 3 and the lower support frame 5 to slide and retract into the outer shell, thereby lowering the tension elastic support part 1 and restoring it to its normal state. During use, due to the resistance between the concave notch 15 and the rigid toothed surface 16 of the inner edge of the mounting groove 10, the upper support frame 3 and the lower support frame 5 are locked, keeping the elastic support part 1 fixed. Therefore, the retraction action of the upper support frame 3 and the lower support frame 5 can only occur under the external force of the rotating cover 14.

[0031] In this embodiment, both the outer ends of the upper support frame 3 and the lower support frame 5 are provided with engaging grooves 4, and the side of the elastic support part 1 is provided with a hollow groove 101. The upper and lower inner sides of the hollow groove 101 are provided with slides 103 that cooperate with the engaging grooves 4. There are at least two adjustment components 2, both of which can move within the hollow groove 101. By setting multiple adjustment components 2 that can move independently inside the elastic support part 1, the elastic support part 1 can provide individual traction and fixation for the left, right and posterior sides of the neck. Especially for patients with torticollis, it can stretch the neck muscle groups at different positions of the neck, relieve neck muscle tension, and make the torticollis correction effect more significant. It can not only meet the needs of ordinary neck brace wearers, but also meet the needs of torticollis wearers.

[0032] In this embodiment, the elastic support 1 is an integral structure design; according to the ergonomic streamline design, the elastic support 1 fits the neck better.

[0033] In this embodiment, the tooth width of the main drive gear 8 is greater than that of the upper gear 6 and the lower gear 7. The lower tooth width of the main drive gear 8 meshes with the upper gear 6, and the upper tooth width of the main drive gear 8 meshes with the lower gear 7. In use, the main drive gear 8 engages with the upper gear 6 and the lower gear 7 respectively. During the transmission process, the upper gear 6 and the lower gear 7 respectively engage with the right rack 301 and the left rack 501, thereby driving the upper support frame 3 and the lower support frame 5 to move.

[0034] In this embodiment, a cover 9 is provided on the back of the outer shell. The cover 9, the main drive gear 8, the adjusting plate 11 and the rotating cover 14 are provided with matching fixing holes 12, and the fixing holes 12 of the rotating cover 14 are provided with connecting threads 13. The threaded pins are connected with the connecting threads 13 to fix the cover 9 and the rotating cover 14, so that the adjusting assembly 2 forms a whole.

[0035] In specific implementation, the elastic support part 1 is fitted onto the neck of the patient or user. The fit between the elastic support part 1 and the neck is adjusted by manually adjusting the fastening length of the fixing sleeve 102, making it fit the neck better to protect the cervical spine. The cover 14 is manually rotated clockwise, causing the upper support frame 3 and the lower support frame 5 to slide upward and downward toward the outside of the outer shell, thereby raising and stretching the elastic support part 1, increasing the stretching of the neck muscles, and relieving neck muscle tension. The positions of the multiple adjustment components 2 are moved so that the elastic support part 1 can provide individual traction and fixation to the left, right, and back of the neck, enabling stretching of the neck muscles at different positions and relieving neck muscle tension. This makes the torticollis correction effect more significant, meeting the needs of both ordinary neck brace wearers and torticollis wearers.
