Description

Technical Field

[0001] The utility model relates to the technical field of oral equipment, and more specifically, to a rubber dam face bow. Background Art

[0002] As a key surgical field isolation tool, rubber dam is gradually being widely used in high-end clinics and special clinics in dental hospitals.

[0003] It mainly combines a soft rubber sheet with different types of clips and a rubber dam face bow. The soft rubber sheet is fixed to the rubber dam face bow by the clip, which effectively isolates the tooth area that needs to be treated, thereby creating a dry, clean and sterile working environment. For example, the existing patent CN219516638U discloses a face bow that is convenient for fixing a saliva suction tube, including a face bow, a saliva suction tube and a fixing device, which can not only fix the rubber dam, but also the saliva suction tube. However, the face bow is only a U-shaped rod, and the rubber dam is laid flat on the U-shaped rod and installed on the patient's mouth. During the flushing operation to clean the surgical area, since the patient needs to raise his head during the oral treatment process, the front side of the rubber dam and the rubber dam face bow combination structure is not blocked, and the flushing liquid is easy to splash onto the patient's face.

[0004] Therefore, a rubber dam face bow is designed with a raised front side. When the rubber dam is fixed on the rubber dam face bow, a shielding plate is formed at the front end, which makes it less likely for the flushing fluid to splash onto the patient's face. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a rubber dam face bow, the front side of which is tilted, and when the rubber dam is fixed on the rubber dam face bow, a shielding plate is formed at the front end, so that the flushing liquid is not easily splashed onto the patient's face.

[0006] In order to solve the above technical problems, the utility model provides a rubber dam face bow, including a face bow body and a rubber dam. The face bow body is provided with a plurality of fixing protrusions for fixing the rubber dam. The face bow body is U-shaped and includes a cross bar, vertical bars connected at both ends of the cross bar, and a shielding bar formed by one end of the vertical bar being upwardly tilted, and a rubber dam is connected between the two shielding bars.

[0007] In at least one embodiment, the vertical rod is hinged to the shielding rod; a groove-shaped pivot seat is provided at the hinged end of the vertical rod, the end of the shielding rod is inserted into the groove of the pivot seat, and the pivot seat is provided with a pivot passing through both sides of the pivot seat and the shielding rod; a fastener for fastening the shielding rod is connected between the vertical rod and the shielding rod.

[0008] The utility model achieves at least the following beneficial effects:

[0009] The facebow body of the present utility model tilts upward, and the rubber dam is connected between two shielding rods, forming a barrier at the front end of the facebow body. When flushing the operation area to clean it, it is not easy for the flushing liquid to splash onto the patient's face. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Aiming at the drawback that the facebow in the prior art is prone to splashing the flushing liquid onto the patient's face. After careful analysis by the inventor, it is found that the main reason for the above technical problem is that the existing facebow is only a U-shaped rod, and the rubber dam is laid flat on the U-shaped rod and installed on the patient's mouth. During the flushing operation to clean the surgical area, since the patient needs to raise his head during oral treatment, there is no shielding at the front side of the rubber dam and facebow combination structure, and it is easy to splash the flushing liquid onto the patient's face. Based on the above analysis, the inventor designs a rubber dam facebow with a front end tilted up. When the rubber dam is fixed to the rubber dam facebow, a shielding plate can be formed at the front end, and it is not easy to splash the flushing liquid onto the patient's face.

[0019] As Figures 1 to 3 shown, in the first embodiment of the present invention, the rubber dam facebow includes a facebow body 1 and a rubber dam 2. The facebow body 1 is provided with a plurality of fixing protrusions 3 for fixing the rubber dam 2. The facebow body 1 is U-shaped and includes a cross bar 11, vertical bars 12 connected to both ends of the cross bar 11, and a shielding bar 13 formed by tilting up one end of the vertical bar 12. A rubber dam 2 is connected between the two shielding bars 13.

[0020] The vertical bar 12 is hinged to the shielding bar 13; a groove-shaped pivot seat 14 is provided at the hinged end of the vertical bar 12. The end of the shielding bar 13 is inserted into the groove of the pivot seat 14. The pivot seat 14 is provided with a pivot shaft 15 passing through both sides of the pivot seat 14 and the shielding bar 13; a fastener 4 for fastening the shielding bar 13 is connected between the vertical bar 12 and the shielding bar 13. The pivot seat 14 is a U-shaped elastic plate. One end of the pivot shaft 15 is fixedly connected to one side of the opening of the U-shaped elastic plate. The other end of the pivot shaft 15 can telescopically pass through the other side of the opening of the U-shaped elastic plate and is connected with a fastener 4; the shielding bar 13 is rotatably sleeved on the pivot shaft 15. The shielding bar 13 can adjust the angle, and the angle between the shielding bar 13 and the vertical bar 12 can be adjusted according to the usage situation. Connecting the rubber dam 2 between the two shielding bars 13 forms a barrier with a groove at the front end of the facebow body 1. When the patient raises his head for oral treatment, not only is it not easy for the flushing liquid to flow to the patient's face, but it is also not easy for the flushing liquid to splash onto the patient's face when it impacts the barrier. The elastic force of the U-shaped elastic plate is used to clamp the shielding bar 13, and there will be some damping effects during the process of rotating the shielding bar 13, which is beneficial for us to adjust the shielding bar 13 to a suitable angle.

[0021] Among them, the fastener 4 is a nut. The nut has a structure with an open end and a hollow interior. The nut is sleeved on the pivot 15 and is threadedly connected thereto. After the nut rotates, the nut abuts against the pivot seat 14. A chute 41 is provided on the inner wall of the nut. One end of the pivot 15 protrudes with a sliding ring 42. The sliding ring 42 is slidably inserted into the chute 41. A limiting block 43 is provided on the opening side of the chute 41. The nut is provided with a knob 44. The elastic clamping force of the U-shaped elastic plate combined with the nut structure realizes the fixation of the shielding rod 13. The nut structure restricts the opening of the U-shaped elastic plate from becoming larger, and the shielding rod 13 is not easily rotated. Since there is a limiting block 43 in the chute 41, the sliding ring 42 can only slide in the chute 41, the nut is not easily separated from the pivot 15, and the nut is not easily lost.

[0022] As Figure 4 shown, compared with the first embodiment of the present invention, the difference lies in the fastener 4. The fastener 4 is a nut. The nut has a structure with both ends open and a hollow interior. The nut is sleeved on the pivot 15 and is threadedly connected thereto. A sliding ring 42 is provided at the suspended end of the pivot 15. The sliding ring 42 on the pivot 15 restricts the nut on the pivot 15, and the nut is not easily lost. The elastic clamping force of the U-shaped elastic plate combined with the nut structure realizes the fixation of the shielding rod 13. The nut structure restricts the opening of the U-shaped elastic plate from becoming larger, and the shielding rod 13 is not easily rotated; at the same time, the suspended end of the pivot 15 is exposed outside and can be used to fix the rubber dam 2, making the connection between the rubber dam 2 and the facebow body 1 more stable.

[0023] All of the above embodiments are exemplary rather than restrictive. Those skilled in the art, under the concept of the present invention, make various modifications or deformations to the specific embodiments described above, and all should be within the protection scope of the present invention.
