Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a rubber barrier flipper. Background Technology
[0002] In dental treatment, rubber dams are commonly used to isolate the tooth to be treated from the rest of the oral cavity, exposing the tooth in isolation. There are two main methods for using rubber dams for isolation: one involves first fitting a perforated rubber dam 9 onto the two wings of the rubber dam clamp 8 (wing method, such as...). Figure 14 (as shown) or bow ring (bow technique, such as) Figure 20 (As shown) Then, the rubber dam clip 8 is clamped onto the corresponding tooth position. Another method is to first clamp the rubber dam clip 8 onto the tooth body, and then slip the perforated rubber dam 9 over the two wings and the arch ring of the rubber dam clip 8 (rubber dam clip priority method, such as...). Figure 20 (As shown). Regardless of the type, after attaching the clamp, the rubber barrier cloth on the rubber barrier clamp should be folded under the rubber barrier clamp so that the rubber barrier cloth is tightly attached to the tooth body to achieve the isolation effect.
[0003] In the known barrier-flipping methods, the inventors primarily use the filling instrument 10 to fold the perforated edge of the rubber dam 9 over the rubber dam clamp 8 to fit the gingiva, and then use a probe to fold the perforated edge of the rubber dam 9 into the gingival sulcus to achieve better isolation. However, neither the filling instrument nor the probe is a dedicated barrier-flipping tool. Due to the limitations of the filling instrument 10's head shape, it can still be used for barrier-flipping when applied to the wing method (e.g., Figure 15 As shown), but when using the bow method and the rubber barrier clamp priority method (such as... Figure 21 As shown in the figure, it is often difficult to obtain a good operating angle and effect. The tip of the probe is relatively sharp, and improper operation may damage the rubber dam or even the patient's soft tissue. Utility Model Content
[0004] The purpose of this invention is to solve the aforementioned technical problems by providing a rubber dam vaulting device. The vaulting end has arc-shaped heads arranged in a cross shape, thus forming four arrangement directions. This allows for vaulting using the wing method, bow method, and rubber dam clamp priority method, making it widely applicable. By utilizing the flat head of the vaulting end, the edge of the rubber dam can be effectively folded into the gingival sulcus, avoiding the problem of easily injuring the patient when using a probe for vaulting. Moreover, both vaulting and folding actions can be performed using this rubber dam vaulting device, avoiding the hassle of changing instruments, saving treatment time, and improving treatment efficiency.
[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides a rubber barrier flipper, including a handheld rod.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0046] This embodiment provides a rubber barrier flipper, such as Figures 1 to 26 As shown, the device includes a handheld lever, which comprises a flipping end 1 and a folding end 2. The flipping end 1 is bent, creating an angle between it and the handheld lever. The folding end 2 can be bent or left unbent; bending it facilitates operation in the posterior tooth area. The flipping end 1 has four arc-shaped heads 5, with the inner arc surface of each head 5 facing away from the handheld lever. These arc-shaped heads 5 are primarily used to flip the edge of the rubber dam over the rubber dam clamp 8. Therefore, the thickness of the arc-shaped heads 5 gradually decreases from the end closer to the flipping end 1 towards the end further away (see reference). Figure 9 In this diagram, T represents the thickness direction of the arc-shaped head 5. This thinning of the end of the arc-shaped head 5 makes it easier to operate between the side wings of the rubber barrier 9 and the rubber barrier clamp 8. The four arc-shaped heads 5 are arranged in a cross shape. The central normal of the cross coincides with the central axis of the barrier-crossing end 1. One straight line in the cross is coplanar with the axis of the handheld rod, meaning the line connecting two of the arc-shaped heads 5 is coplanar with the axis of the handheld rod (these two arc-shaped heads 5 can be defined as the front and rear arc-shaped heads 5). The line connecting the other two arc-shaped heads 5 is perpendicular to the axis of the handheld rod (these two arc-shaped heads 5 can be defined as the left and right arc-shaped heads 5). Generally, the left and right arc-shaped heads 5 are mainly used for barrier-crossing operations using the wing method (see reference). Figure 16 and Figure 17 The two arc-shaped heads, front and rear, are mainly used for obstacle-crossing operations using the bow method or the clamp-first method (see reference). Figure 22 and Figure 23 Of course, depending on the actual situation, the left and right curved heads 5 can also be used for dam flap operations using the arch method or the clamp-first method, and the front and rear curved heads 5 can also be used for dam flap operations using the wing method. The choice mainly depends on the tooth position and different usage scenarios. The folded end 2 has a flat head 6. The flat head 6 of the folded end 2 is mainly used to fold the edge of the rubber dam into the gingival sulcus after the rubber dam clamp 8 and rubber dam 9 are in place. Therefore, the thickness of the flat head 6 gradually decreases from the end closer to the folded end 2 to the end farther away from the folded end 2 (see reference). Figure 13 In this context, T represents the thickness direction of the flattened head 6. This thinning of the end of the flattened head 6 allows for better insertion into the gingival sulcus and folding action (see reference). Figure 25 and Figure 26 Furthermore, the flat head 6 of the folding end 2 can also be used for overturning obstacles in wing-type structures (see reference). Figure 18 and Figure 19).
[0047] The four arc-shaped heads 5 of the dam-flipping end 1 of this rubber dam flipping device can accommodate the wing method, bow method, and rubber dam clamp priority method, making it widely applicable. The flat head 6 of the folding end 2 can effectively fold the edge of the rubber dam into the gingival sulcus, and the design of the flat head 6 can avoid the problem of probe tip injury. In addition, both the dam flipping and folding actions can be completed using this rubber dam flipping device, avoiding the cumbersome process of changing instruments, saving treatment time, and improving treatment efficiency.
[0048] In one implementation, such as Figures 1 to 26 As shown, the width of the arc-shaped head 5 gradually decreases (reference). Figure 10 (W in the figure represents the width direction of the arc-shaped head 5). This narrowing of the end of the arc-shaped head 5 makes it easier to enter the space between the rubber barrier 9 and the side wings of the rubber barrier clamp 8 for operation.
[0049] In one implementation, such as Figures 1 to 26 As shown, the folded end 2 is bent along the direction of the flat surface parallel to the flat head 6, which facilitates operation in the posterior tooth area.
[0050] In one implementation, such as Figures 1 to 26 As shown, the bending directions of folding end 2 and folding end 1 are different to avoid mutual interference during operation. Of course, if necessary, the bending directions of folding end 2 and folding end 1 can be the same.
[0051] In one implementation, such as Figures 1 to 26 As shown, the bends at both the overturning end 1 and the overturning end 2 are rounded to avoid cutting the patient's oral tissue.
[0052] In one implementation, such as Figures 1 to 26 As shown, the bending angle of the overturning end 1 is 120° to 150° and the bending angle of the overturning end 2 is 120° to 150°.
[0053] In one implementation, such as Figures 1 to 26 As shown, a barrier cloth retaining ring 7 is coaxially provided on the overturning end 1 to prevent the barrier cloth from sliding.
[0054] In one implementation, such as Figures 1 to 26 As shown, the flat head 6 has a smooth end face, that is, the end of the flat head 6 is a smooth arc surface.
[0055] In one implementation, such as Figures 1 to 26 As shown, the handheld handle includes a first grip section 3 and a second grip section 4. One end of the first grip section 3 is provided with a flip end 1, and one end of the second grip section 4 is provided with a folding end 2. The other end of the first grip section 3 is connected to the other end of the second grip section 4. Both the first grip section 3 and the second grip section 4 are streamlined, with small ends and a large middle, which facilitates gripping and pinching.
[0056] In one implementation, such as Figures 1 to 26 As shown, the cross-section of the first grip section 3 and the second grip section 4 is triangular, meaning that the first grip section 3 and the second grip section 4 are roughly triangular prisms. This better fits the fingers when pinching, and makes it easier to rotate the handle to adjust the angle during use. All three angles of the triangle are rounded, meaning the edges of the triangular prism are rounded, improving the comfort of pinching the fingers.
[0057] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
