Description

Technical Field

[0002] During the design and production of oral prostheses, the positional relationship between the maxilla and the temporomandibular joint needs to be transferred to the articulator, and the face bow is a special device for determining the positional relationship between the maxilla and the temporomandibular joint and transferring it to the articulator. Due to individual differences, the maxillary arch of some patients may be located near the midpoint of the line connecting the bilateral condyles, may be tilted left and right, or may be tilted front and back, which is difficult to judge clinically. The only accurate method is to use the face bow for recording and transfer to ensure that the dentures produced are consistent with the actual situation in the mouth. The face bow is an important device to ensure the refinement of denture production.

[0003] The utility model patent with patent application announcement number CN208851665U discloses a face bow with a horizontal positioning device, which is specifically composed of a horizontal center adjustment frame, a side bracket, a nose support, a jaw fork, a support rod, a support frame, a support rod fastening bolt, a universal joint, a universal joint fastening rod, an external auditory canal support ball, a condylar pointer, a horizontal side fastening bolt, an adjustment bolt, a slide, and a leveling device. The utility model sets a leveling device on the center adjustment frame, the side bracket or the support frame, which enables doctors to more conveniently determine whether the face bow is parallel to the horizontal plane from the front or side, and solves the problem that the bow body may be deflected due to the doctor's subjective judgment. In addition, the leveling device is bonded to the center adjustment frame, the side bracket or the support frame by double-sided tape or Velcro, which provides convenience for changing the position of the leveling device at any time.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is the nose brace provided thereon, which has a fixed shape. However, due to individual differences among wearers, different people have different nose bridge shapes.

[0037] Among them, the adjustment component includes a fixed sleeve 2 fixedly connected to the outer side of the support plate 1, a sliding column 3 is slidably connected inside the fixed sleeve 2, a first adjustment bolt 4 is rotatably connected inside the fixed sleeve 2 through a thread, and the end of the first adjustment bolt 4 abuts against the sliding column 3.

[0038] In addition, the adjustment assembly also includes a sliding tube 5 fixedly connected to the top of the sliding column 3, the sliding tube 5 penetrates the sliding column 3, a push rod 6 is slidably connected inside the sliding tube 5, a second adjusting bolt 7 is rotatably connected to the top of the sliding column 3 through a thread, the second adjusting bolt 7 penetrates the sliding column 3 and the sliding tube 5 and abuts against the push rod 6, and the end of the push rod 6 is fixedly connected to the fixed block 8.

[0039] Through the above components, when the nose support plate 10 is needed to support the position of the patient's nose bridge, the first adjusting bolt 4 can be rotated to separate the first adjusting bolt 4 from the slide column 3, so that the position of the slide column 3 can be adjusted, and then the second adjusting bolt 7 is rotated to separate the second adjusting bolt 7 from the push rod 6, and then the push rod 6 can be pushed to drive the nose support plate 10 to abut against the patient's nose bridge, and then continue to push to compress the spring 11, and then the second adjusting bolt 7 is rotated to fix the position of the push rod 6 and keep the spring 11 in a compressed state. When the shape of the patient's nose bridge is different, the springs 11 at different positions will retract and extend in different situations, so that the nose support plate 10 can be more suitable for nose bridges of different shapes.

[0040] Reference Figure 1 and Figure 2 The transmission assembly includes a force transmission rod 12 rotatably connected to the inside of the support plate 1, a knob 13 is fixedly connected to the top of the force transmission rod 12, a gear 14 is fixedly sleeved on the outside of the force transmission rod 12, and racks 15 are respectively meshed at both ends of the outer side of the gear 14. The two racks 15 are arranged opposite to each other, and the racks 15 are slidably connected to the support plate 1.

[0041] The connecting assembly includes a slide bar 16 fixedly connected to the inner side of the ends of the two racks 15 . The slide bar 16 is slidably connected to the opposite racks 15 , and a connecting sleeve rod 17 is fixedly connected to the ends of the racks 15 .

[0042] In addition, the positioning assembly includes a connecting slide rod 18 that is slidably connected to the inside of the connecting sleeve rod 17. The inside of the connecting sleeve rod 17 is connected to a third adjusting bolt 20 by threaded rotation. The third adjusting bolt 20 abuts against the connecting slide rod 18.

[0046] The adjusting lever 24 can then be rotated, thereby changing the angle of the jaw fork 25 .

[0047] Working principle: when the nose support board 10 is needed to support the position of the patient's nose bridge, the first adjusting bolt 4 can be rotated to separate the first adjusting bolt 4 from the slide column 3, so that the position of the slide column 3 can be adjusted, and then the second adjusting bolt 7 is rotated to separate the second adjusting bolt 7 from the push rod 6, and then the push rod 6 can be pushed to drive the nose support board 10 to abut against the patient's nose bridge, and then continue to push. The nose support board 10 will apply different pressures to the springs 11 at different positions due to the different heights of the force points, so that the springs 11 at different positions are compressed to different degrees, and then the second adjusting bolt 7 is rotated to fix the position of the push rod 6 and keep the spring 11 in a compressed state. When the shape of the patient's nose bridge is different, the springs 11 at different positions will retract and stretch in different situations, so that the nose support board 10 can be more suitable for nose bridges of different shapes;

[0048] When it is necessary to adjust the distance between the two external auditory canal supports 19, the knob 13 can be rotated to drive the force transmission rod 12 to rotate, thereby driving the gear 14 to rotate, thereby driving the two racks 15 to move relative to each other, thereby driving the distance between the two external auditory canal supports 19 to change. When it is necessary to change the distance between the external auditory canal support 19 and the rack 15, the third adjusting bolt 20 can be rotated to separate the third adjusting bolt 20 from the connecting slide rod 18, so that the connecting slide rod 18 can be pulled to change the distance between the external auditory canal support 19 and the rack 15.
