Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a rubber dam punching board. Background Art

[0002] A rubber dam (also called an isolation rubber dam), as the name implies, is a rubber cloth that separates "water". It exposes the tooth to be treated alone, isolates other parts of the oral cavity from the treatment area of the tooth, avoids interference caused by the movement of the patient's tongue and saliva to the treatment area, and can prevent the accidental swallowing or aspiration of small instruments or material debris during the operation, protect soft tissues from the stimulation of the liquid medicine, prevent damage to soft tissues by rotating instruments or manual instruments, and at the same time protect medical staff from isolating blood and saliva and avoid cross-infection caused by liquid splashing, providing a clear surgical field of view for treatment and facilitating treatment operations.

[0003] Before treatment, it is necessary to punch holes in the rubber dam. Through the holes, the tooth position to be treated is exposed. When punching holes in the rubber dam cloth for different tooth positions, in order to make the punching area in a reasonable position and facilitate treatment operations, a rubber dam punching board is needed to position the rubber dam. As Figure 7 shown in the figure is an existing rubber dam punching board. The rubber dam punching board is mainly composed of an opaque plate body 18.

Detailed implementation manners

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] This embodiment provides a rubber dam punching plate, as Figures 1 to 6 shown, which includes a transparent plate body 1, and a positioning area is provided on the transparent plate body 1. The positioning area is consistent with the size and shape of the rubber dam. Generally speaking, the rubber dam is a square cloth, and the corresponding positioning area is also a square area. Of course, if the rubber dam is of other shapes, the corresponding positioning area is also of the corresponding shape. A cross center line is provided in the positioning area, and the positioning area uses the cross center line as a coordinate system 2 with an x-axis and a y-axis, dividing the positioning area into four quadrants. Among them, the right upper jaw tooth position holes are provided in the first quadrant, and the right upper jaw tooth position holes correspond to the right upper jaw tooth positions of the human body. The left upper jaw tooth position holes are provided in the fourth quadrant, and the left upper jaw tooth position holes correspond to the left upper jaw tooth positions of the human body. The right lower jaw tooth position holes are provided in the second quadrant, and the right lower jaw tooth position holes correspond to the right lower jaw tooth positions of the human body. The left lower jaw tooth position holes are respectively provided in the third quadrant, and the left lower jaw tooth position holes correspond to the left lower jaw tooth positions of the human body.

[0028] Working principle:

[0029] When in use, press the transparent plate body 1 on the rubber dam so that the positioning area corresponds to the rubber dam. If it is not necessary to adjust the relative positions of the punching plate and the rubber dam up, down, left, or right, then find the tooth position holes corresponding to the teeth to be treated of the corresponding patient, and punch holes in the rubber dam through the tooth position holes to form tooth holes 16. If it is necessary to adjust the relative positions of the punching plate and the rubber dam up, down, left, or right, then move the transparent plate body 1, and after moving to a suitable position, find the tooth position holes corresponding to the teeth to be treated of the corresponding patient, and punch holes in the rubber dam through the tooth position holes to form tooth holes 16. Since the transparent plate body 1 is a transparent body, it will not be affected by the thickness, color, and transparency of the rubber dam itself during movement, and is also relatively less affected by environmental light.

[0030] When performing rubber dam punching operations for different tooth positions, in order to make the punching area in a reasonable position and facilitate treatment operations, it is often necessary to adjust the relative positions of the punching plate and the rubber dam cloth up, down, left, and right. For example, when punching the upper anterior teeth, the rubber dam cloth needs to be moved upward by about 2 cm relative to the punching plate; when punching the upper right posterior teeth, the rubber dam cloth needs to be moved upward and to the right relative to the punching plate; when punching the lower left posterior teeth, the rubber dam cloth needs to be moved downward and to the left relative to the punching plate, etc. Operators with less experience often cannot accurately estimate the moving distance, resulting in problems such as hole position deviation, affecting the treatment operation space. Seriously, it may even be necessary to replace the rubber dam cloth and re-perform the punching operation, causing waste, prolonging the patient's waiting time, and reducing the treatment efficiency. To meet this need, in this embodiment, as Figures 1 to 6 shown, scale lines 4 are provided on the cross center line, that is, scale lines 4 are provided on both the y-axis and the x-axis of the coordinate system 2. The operator can accurately move the relative positions of the rubber dam punching plate and the rubber dam in all directions according to the scale lines 4 as needed, making the punching positioning more accurate and the punching position more reasonable. The accuracy of the scale lines 4 is usually 1 mm to 10 mm.

[0031] In this embodiment, as Figures 1 to 6 shown, a positioning corner mark hole 5 is provided in the first quadrant. After punching the rubber dam, a mark can be made on the rubber dam through the positioning corner mark hole 5, leaving a mark point 15 to clarify the orientation of the tooth hole 16, facilitating subsequent installation at the corresponding tooth position of the patient.

[0032] In this embodiment, as Figures 1 to 6 shown, a first digital identifier is provided in the first quadrant, and the first digital identifier corresponds to the upper right maxillary tooth position hole. A second digital identifier is provided in the second quadrant, and the second digital identifier corresponds to the right mandibular tooth position hole. A third digital identifier is provided in the third quadrant, and the third digital identifier corresponds to the left maxillary tooth position hole. A fourth digital identifier is provided in the fourth quadrant, and the fourth digital identifier corresponds to the left mandibular tooth position hole. According to the digital identifiers, the corresponding tooth position holes can be directly selected for marking according to the required tooth position, which is intuitive, convenient, time-saving, and improves the marking efficiency and accuracy. The first digital identifier, the second digital identifier, the third digital identifier, and the fourth digital identifier can be Arabic numerals, or Chinese numerals (including uppercase and lowercase), or Roman numerals.

[0033] In this embodiment, as Figures 1 to 6 shown, the first digital identifier and the fourth digital identifier increase gradually in number from large to small along the y-axis. For example, the first digital identifier and the fourth digital identifier are arranged in the order of 1, 2, 3, 4, 5, 6, 7, 8 from the positive coordinate of the y-axis to the origin. The second digital identifier and the third digital identifier increase gradually in number from small to large along the y-axis. For example, the second digital identifier and the third digital identifier are arranged in the reverse order of 1, 2, 3, 4, 5, 6, 7, 8 from the origin of the y-axis to the negative coordinate.

[0034] Generally, the sizes of the rubber dam 14 for permanent teeth (also known as the rubber dam for adults) and the rubber dam 17 for primary teeth (also known as the rubber dam for children) are different. Usually, users need to prepare two traditional rubber dam punching plates of different sizes. To solve this problem, in this embodiment, as Figures 1 to 6 shown, the positioning area includes a positioning area for permanent teeth and a positioning area for primary teeth. The positioning area for primary teeth is located within the positioning area for permanent teeth. The positioning area for primary teeth and the positioning area for permanent teeth share a cross center line as a common coordinate system 2. The positioning area for permanent teeth is consistent with the size and shape of the rubber dam 14 for permanent teeth, and the positioning area for primary teeth is consistent with the size and shape of the rubber dam 17 for primary teeth. The upper right jaw tooth position holes include an upper right jaw permanent tooth position hole 6 and an upper right jaw primary tooth position hole 10. The upper right jaw permanent tooth position hole 6 corresponds to the upper right jaw tooth position of an adult, and the upper right jaw primary tooth position hole 10 corresponds to the upper right jaw tooth position of a child. The upper left jaw tooth position holes include an upper left jaw permanent tooth position hole 7 and an upper left jaw primary tooth position hole 11. The upper left jaw permanent tooth position hole 7 corresponds to the upper left jaw tooth position hole of an adult, and the upper left jaw primary tooth position hole 11 corresponds to the upper left jaw tooth position hole of a child. The lower right jaw tooth position holes include a lower right jaw permanent tooth position hole 8 and a lower right jaw primary tooth position hole 12. The lower right jaw permanent tooth position hole 8 corresponds to the lower right jaw tooth position hole of an adult, and the lower right jaw primary tooth position hole 12 corresponds to the lower right jaw tooth position hole of a child. The lower left jaw tooth position holes include a lower left jaw permanent tooth position hole 9 and a lower left jaw primary tooth position hole 13. The lower left jaw permanent tooth position hole 9 corresponds to the lower left jaw tooth position hole of an adult, and the lower left jaw primary tooth position hole 13 corresponds to the lower left jaw tooth position hole of a child.

[0035] When in use, if punching the rubber dam 14 for permanent teeth, press the rubber dam punching plate on the rubber dam 14 for permanent teeth so that the rubber dam 14 for permanent teeth corresponds to the positioning area for permanent teeth. If no relative position adjustment is required subsequently, directly punch the hole. If adjustment is required subsequently, after adjusting the relative position, subsequent punching can be carried out. If punching the rubber dam 17 for primary teeth, press the rubber dam punching plate on the rubber dam 17 for primary teeth so that the rubber dam 17 for primary teeth corresponds to the positioning area for primary teeth. If no relative position adjustment is required subsequently, directly punch the hole to form the tooth hole 16. If adjustment is required subsequently, after adjusting the relative position, subsequent punching can be carried out to form the tooth hole 16. This rubber dam punching plate combines the punching plate for permanent teeth and the punching plate for primary teeth into one, and can be used for both adult and child rubber dams with one plate, without the need to prepare multiple punching plates. Generally, the rubber dam 17 for primary teeth is a square cloth, and the corresponding positioning area for primary teeth is also a square area. Of course, if the rubber dam 17 for primary teeth is of other shapes, the corresponding positioning area for primary teeth is also of the corresponding shape. Preferably, when there are both permanent tooth position holes and primary tooth position holes, only one set of digital markings can be set, that is, there is one set of digital markings beside the permanent tooth position holes, without the need to set one set of digital markings beside each of the permanent tooth position holes and the primary tooth position holes. Of course, setting one set of digital markings beside each can also be done, but it will cause visual confusion. Of course, one set of digital markings can also be located beside the primary tooth position holes.

[0036] Furthermore, in this embodiment, asFigures 1 to 6 As shown, the corners of the deciduous tooth positioning area are provided with corner positioning lines 3, which facilitate the positioning correspondence between the deciduous tooth positioning area and the deciduous tooth rubber dam 17. Specifically, because the deciduous tooth rubber dam 17 is square, the deciduous tooth positioning area is square, so the four corners of the deciduous tooth positioning area are provided with corner positioning lines 3.

[0037] Further, in this embodiment, if Figures 1 to 6 As shown, the shape and size of the transparent plate body 1 are consistent with the permanent tooth positioning area, that is, the entire surface of the transparent plate body 1 is the permanent tooth positioning area, so when the permanent tooth rubber dam 14 is positioned corresponding to the permanent tooth positioning area, the edge of the permanent tooth rubber dam 14 and the edge of the transparent plate body 1 are directly aligned, so there is no need to draw a positioning corner mark for the permanent tooth positioning area. Of course, if the size of the permanent tooth positioning area is smaller than the transparent plate body 1, a positioning corner mark can also be drawn on the permanent tooth positioning area to facilitate positioning.

[0038] In this embodiment, Figures 1 to 6 As shown, the parts of the y-axis located in the first and fourth quadrants are marked with the maxillary name, which can be in Chinese, English or other characters, such as MAXILLARY in English and MAXILLARY in Chinese. The parts of the y-axis located in the second and third quadrants are marked with the mandibular name, which can be in Chinese, English or other characters, such as MANDIBULAR in English and MAXILLARY in Chinese. With the name marking, it is convenient to distinguish which part of the transparent plate 1 is the maxillary part and which part is the mandibular part.

[0039] Conventional rubber dam perforated plates are usually made of paper and cannot be sterilized. Moreover, if they are accidentally stained with liquid or damp during use, they will deform, change color, or even be damaged. In order to avoid the above problems, in this embodiment, Figures 1 to 6 As shown, the transparent plate 1 can be made of resin, glass or wax paper, which is waterproof and durable, and can be soaked or wiped for disinfection. Of course, considering the weight, fragility, hardness, strength and other parameters, resin material is preferred, which is light, not easy to break, and not easy to damage. The transparent plate 1 can be fully transparent or translucent.

[0040] In this embodiment, Figures 1 to 6 As shown, the transparent board body 1 has a matte frosted board surface. The matte surface can reduce visual fatigue, and the frosted surface can reduce touch marks and scratches on the board surface.

The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope.
