Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0026] The utility model aims at providing a rubber dam clamp to solve the problems in the prior art, so that the distance between the bow part and the clamping part of the rubber dam clamp can be adjusted according to actual conditions.

[0027] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail below in conjunction with the drawings and specific implementation.

[0028] As Figures 1-4 Indicated, the utility model provides a rubber dam clamp: including bow part 1 and clamping part 14;

[0029] The bow part 1 plays the role of providing the clamping force, and two bow part clamping arms 2 are symmetrically and fixedly connected to the two ends of the bow part 1, the bow part clamping arm insertion slot 3 is arranged on the lower end face of the bow part clamping arm 2, the threaded hole 4 is arranged on the bow part clamping arm 2, and the threaded hole 4 is communicated with the bow part clamping arm insertion slot 3;

[0030] The clamping part 14 is two, and the two clamping parts 14 are symmetrical about the symmetry axis of the two bow part clamping arms 2, the clamping wing 9 for supporting rubber cloth is arranged on the side of the clamping part 14 away from the symmetry axis, the clamping beak 11 is arranged on the side of the clamping part 14 close to the symmetry axis, the clamping beak 11 is used to clamp the dental tissue, the through hole 10 is arranged on the clamping part 14 between the clamping wing 9 and the clamping beak 11, and the through hole 10 is used for the fixation of the rubber dam clamp forceps;The clamping part extension rod 7 is fixed to the upper end of the clamping part 14, the clamping part extension rod 7 is inserted into the bow part clamping arm insertion slot 3 in a matched mode, and after the clamping part extension rod 7 is inserted into the bow part clamping arm insertion slot 3, the bolt 6 is screwed in the threaded hole 4 to be tightly fixed.

[0031] In use, the clamping part extension rod 7 of the clamping part 14 is inserted into the arch part clamping arm slot 3, and is fixed by the bolt 6, so that the distance between the arch part 1 and the clamping part 14 can be adjusted according to the space in the oral cavity, so that the arch part 1 of the rubber dam clamp is as far away from the operation area as possible, the operation field of view is enlarged, and a larger operation space is obtained, which greatly improves the treatment efficiency and treatment quality. At the same time, the adjustable mode makes the rubber dam clamp suitable for the oral cavities of patients of different age groups, thereby improving the application range of the rubber dam clamp.

[0032] As an implementable example, as shown in Figure 1 The clamping beak 11 is provided with a detachable arc-shaped soft pad 13, which has softness and elasticity, can elastically deform according to the shape of the teeth, and can be more closely fitted, thereby improving the sealing performance, better isolating contaminants such as saliva and blood, and increasing the stability of clamping. In particular, when treating cases with uneven dentition or special crown shape, the arc-shaped soft pad 13 can effectively prevent falling or displacement; at the same time, the arc-shaped soft pad 13 can buffer the occlusal force and reduce the damage to the gingival soft tissue, thereby reducing the pain of the patient. The height of the crown is generally 5-10 mm, and the height of the clamping beak 11 is 1 / 2-2 / 3 of the height of the crown, which can provide stable support while reducing the pressure on the gingival soft tissue. The arc-shaped soft pad 13 is provided with at least two types, which are selected according to the size and shape of the teeth during use, thereby further increasing the stability of clamping the teeth; at the same time, different type marks can be provided on the arc-shaped soft pad 13 of different types, so as to facilitate medical staff to quickly identify, for example, three types of large, medium and small are designed and distinguished by three colors of blue, green and yellow, or the specific size is marked on the arc-shaped soft pad 13, or the marks of "large", "medium" and "small" are marked.

[0033] As an implementable example, the included angle between the arch part 1 and the arch part clamping arm 2 is obtuse, for example, the angle is 120°-150°, so that the arch part 1 is inclined backward, thereby further expanding the space of the clamping part 14 and obtaining a larger operation space.

[0034] As an implementable example, the clamping part extension rod 7 is provided with a scale, which is convenient for recording assembly data, and when the patient is treated again, the corresponding scale data can be quickly selected for assembly, thereby improving the treatment efficiency.

[0035] As an implementable example, as shown in Figure 1 The side close to the two arch part clamping arms 2 is provided with an arch part clamping arm reinforcing rib 5, and the wing part clamping arm 8 is arranged at the connection between the clamping part 14 and the clamping part extension rod 7. The wing part clamping arm 8 is provided with a wing part clamping arm reinforcing rib 12 on the side close to and away from the teeth, thereby effectively improving the strength of the rubber dam clamp and avoiding deformation failure due to long-term use.

[0036] As an implementable example, the arch part 1 and the clamping part 14 are all medical-grade stainless steel materials, for example, 304 stainless steel, 316 stainless steel and 316L stainless steel, which have excellent corrosion resistance, ensuring long-term stability and safety of the rubber barrier clamp, and the arc-shaped soft pad 13 is a medical-grade silicone material, which is soft and comfortable, non-toxic and odorless, and will not cause foreign body reaction or inflammation of surrounding tissues.

[0037] The principle and implementation mode of the utility model are described by applying specific examples in the utility model, and the above embodiment is only used for helping to understand the method and core idea of the utility model; meanwhile, for the general technical personnel in the field, the specific implementation mode and application range will be changed according to the idea of the utility model. In conclusion, the content of the specification should not be understood as the limitation of the utility model.
