Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oral medical instruments, in particular to a rubber dam expansion device. Background Art
[0002] Rubber dam is an important component in dental treatment. Its main functions are: to expose the teeth to be treated during dental treatment, and to isolate other parts of the mouth from the treatment area to prevent the patient's tongue movement and saliva from interfering with the treatment area, and to prevent accidental swallowing or aspiration of small instruments or material debris during operation; to protect soft tissue from stimulation by liquid medicine; to prevent damage to soft tissue by rotating instruments or manual instruments; to protect medical staff from blood and saliva, and to avoid cross infection caused by liquid splashing; to provide a clear surgical field of view for treatment and facilitate treatment operations.
[0003] When treating anterior teeth, it is usually necessary to use dental floss to tie a knot around the neck of the tooth and tie the end of the dental floss to the rubber dam bracket to expose the neck of the tooth and obtain a wider operating space and a better field of vision. However, if a traditional rubber dam bracket is used, the dental floss must be wrapped around the main body of the rubber dam bracket to fix it. After the rubber dam cloth is supported, if the position and angle of the dental floss need to be adjusted, the rubber dam cloth needs to be removed from the rubber dam bracket first, and then the dental floss on the neck of the tooth and the rubber dam bracket needs to be cut, and the dental floss needs to be used again to tie a knot around the neck of the tooth and the main body of the rubber dam bracket to make adjustments. The operation process is cumbersome and time-consuming, which increases the waiting time for the patient to open his mouth, causes discomfort to the patient, and reduces the efficiency of treatment.
[0004] Traditional rubber dam expansion devices are generally flat structures, and the rubber dam cloth fixed on them is expanded to form a plane. When treating the posterior teeth, the rubber dam cloth needs to be pulled back to expose the tooth tissue to be treated. However, the physiological structure of the human face is C-shaped when the mouth is open. The use of traditional rubber dam expansion devices will produce a large pulling force on the rubber dam cloth, increasing the risk of the rubber dam cloth and rubber dam clip falling off. The rubber dam that is stretched too tight will also compress the corners of the patient's mouth, causing discomfort to the patient. At the same time, the water storage pocket formed by this flat structure has a small capacity, and the liquid produced by flushing during treatment can easily overflow the rubber dam area, causing contamination.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The utility model aims to provide a rubber dam expansion device to solve the problems existing in the prior art, facilitate the fixing of dental floss, be easy to use, and increase the comfort of patients.
[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0026] like Figure 1-Figure 5 As shown, the present embodiment provides a rubber dam expansion device, including a main body, the main body is used to expand the rubber dam, the side view of the main body is arc-shaped, and the middle part of the main body can be bent in the direction close to the inside of the patient's oral cavity, that is, extend to the corner of the mouth, so that the main body can be close to the mouth opening curve, reduce the tension on the rubber dam, increase the patient's comfort and the stability of the rubber dam, the upper and lower ends of the main body are used to extend to the outside of the patient's oral cavity, thereby forming a three-dimensional shape that conforms to the physiological structure of the human face, that is, the main body is upturned at the position close to the patient's nose and the position close to the patient's chin, so as to avoid compressing the patient's nose after the rubber dam is installed, affecting his breathing, and avoiding compressing the patient's nose after the rubber dam is installed. The patient's jaw is forced to move, causing the patient to feel uncomfortable. A plurality of fixing parts 4 are fixed to the outside of the main body. The end of the fixing part 4 away from the main body is used to fix the edge of the rubber dam, so that the rubber dam is fully stretched, which is convenient for the doctor to operate. A plurality of connecting parts 5 are fixed to the outside of the main body at staggered positions of the fixing parts 4. The end of the connecting part 5 away from the main body is used to fix one end of the dental floss, and the connecting part 5 is located on the side of the fixing part 4 away from the patient's oral cavity, that is, when in use, the connecting part 5 is higher than the fixing part 4, which is convenient for winding and fixing the dental floss through the connecting part 5 to prevent the rubber dam from sliding from the neck of the tooth to the incisal end. The use is convenient, and there is no need to remove the barrier cloth when fixing and removing the dental floss, which does not affect the treatment process.
[0027] Specifically, the front view of the main body can be U-shaped or O-shaped. When the front view of the main body is U-shaped, it includes a first support frame 1, a connecting frame 2, and a second support frame 3. The first support frame 1 and the second support frame 3 are symmetrically arranged at the two ends of the connecting frame 2, and the lower end of the first support frame 1 and the lower end of the second support frame 3 are fixed to the two ends of the connecting frame 2. The front view and the side view of the first support frame 1 and the second support frame 3 are both C-shaped. The middle part of the first support frame 1 and the second support frame 3 is bent to cooperate with the corner of the patient's mouth, so that the main body can be close to the mouth opening curve, reduce the tension on the rubber dam, increase the patient's comfort and the stability of the rubber dam, and the upper end of the first support frame 1 and the upper end of the second support frame 3 are bent in a direction close to each other, and the upper end of the first support frame 1 and the upper end of the second support frame 3 are also bent in a direction away from the inside of the patient's mouth, ensuring that when placed in the patient's mouth, the positions corresponding to the patient's nose and chin are both upturned to avoid affecting the patient's normal breathing and wearing comfort. A clearance is formed between the upper end of the first support frame 1 and the upper end of the second support frame 3.
[0028] A plurality of fixing parts 4 and a plurality of connecting parts 5 are installed on the first supporting frame 1, the connecting frame 2 and the second supporting frame 3, which can ensure the stability of the fixation and expansion of the rubber dam and realize the fixation of multiple dental flosses.
[0029] The fixing parts 4 are evenly arranged on the main body. This arrangement can ensure that the rubber dam is evenly stressed while being fully expanded, reduce the tension on the rubber dam, reduce the patient's discomfort, and make the rubber dam not easily damaged. The fixing parts 4 are conical, and the outer diameter of the fixing parts 4 gradually decreases from approaching to away from the main body. The fixing parts 4 can be used to expand and fix the rubber dam. The conical fixing parts 4 are used to support, fold, and fix the rubber dam. In combination with the outer contour and height of the water blocking dam 6 on the inner side of the main body, a concave water blocking barrier is formed, which effectively prevents contamination caused by overflow of flushing fluid, blood, etc. during dental treatment; the end of the fixing part 4 away from the main body is rounded and blunted, which ensures that the rubber dam can be stably expanded while making the front end of the fixing end not too sharp to avoid damage to the rubber dam.
[0030] The two sides of the fixing part 4 are concave arc surfaces, which conform to structural mechanics and can increase the stability of the fixing part 4 so that it can withstand stronger forces. At the same time, the concave arc surface reduces the width of the front end of the fixing part 4, and a more stable expansion effect can be obtained when the front end of the fixing part 4 is used for rubber dam fixation.
[0031] The connecting portion 5 is in the shape of a letter "7", so that after the dental floss passes around the connecting column 7, it needs to change direction to be inserted into the ring structure 10 in the middle of the V-shaped opening 9. The dental floss that changes direction fully contacts the surface of the ring structure 10, generates friction, and is further fixed; it specifically includes a connecting column 7 and an opening portion 8, one end of the connecting column 7 is fixed to the main body, the other end of the connecting column 7 is fixedly connected to one end of the opening portion 8, and the other end of the opening portion 8 is provided with a V-shaped opening 9, the V-shaped opening 9 is opened in a direction away from the center of the main body, and the directions of the V-shaped openings 9 on each connecting portion 5 are different, the two ends of the V-shaped opening 9 extend in a direction close to each other, the dental floss is inserted (i.e., the open end of the V-shaped opening 9) is wider, which is convenient for the dental floss to enter the ring structure 10, and the opening of the ring structure 10 is narrow, so that the dental floss is not easy to fall out.
[0032] When treating anterior teeth, one end of the dental floss is wrapped around the neck of the tooth where the tooth body needs to be exposed and tied to fix it, and the other end is wrapped around the connecting column 7, and then the dental floss is inserted into the V-shaped opening 9 through the opening 8 to achieve a fixing effect. In this process, the friction between the dental floss and the connecting column 7 can also play a good fixing effect. If the dental floss is removed after the treatment is completed or the angle needs to be adjusted during the treatment, just pull the end of the dental floss out of the V-shaped opening 9 and loosen the dental floss at the connecting column 7. The open end of the V-shaped opening 9 has a guiding function, and the dental floss can be easily inserted into its ring structure 10. During tooth treatment (especially anterior tooth treatment), the tooth body and tooth neck to be treated are fully exposed, and the tightness and angle of the dental floss can be adjusted at any time, providing doctors with a wider field of vision, facilitating treatment operations, and shortening treatment time.
[0033] A water-blocking dam 6 is fixed on the inner side of the main body, and the length of the water-blocking dam 6 is consistent with the length of the main body, and the upper surface of the water-blocking dam 6 is perpendicular to the inner side of the main body, and the cross-section of the structure formed with the main body is L-shaped. The rubber dam is supported, folded, and fixed by the fixing part 4, and the outer contour and height of the water-blocking dam 6 are matched to form a water-blocking barrier with a large capacity, further enhancing the effect of the water-blocking barrier, and effectively preventing contamination caused by overflow of flushing fluid, blood, etc. during dental treatment.
[0034] The present invention uses specific examples to illustrate the principle and implementation of the present invention. 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. In summary, the content of this specification should not be understood as limiting the present invention.
