Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to an easily self-made rubber dam support and a manufacturing method and application thereof. Background Art

[0002] The rubber dam isolation technique was invented by American dentist Sanford Christie Barnum in 1864 and has become an important technique for oral treatment. The rubber dam can effectively block oral fluids such as saliva, gingival sulcus fluid, and blood from the surgical area, and is the most ideal moisture-proof method to keep the surgical area dry. It can separate soft tissues such as lips, tongue, and cheeks from the affected teeth in the surgical area, protect the soft tissues, prevent scratches and burns, and prevent drugs from irritating the oral mucosa and accidentally swallowing the treatment equipment that slips off into the digestive tract or accidentally inhaling it into the respiratory tract, thereby improving the safety of the treatment operation. It can effectively isolate the affected teeth, highlight the surgical field, reduce visual interference, and improve visibility. It can prevent moisture in the mouth from fogging up the mouth mirror, and prevent the water sprayed from the handpiece from entering the mouth, causing the patient to frequently get up to rinse the mouth, making the operation convenient and greatly improving work efficiency.

[0003] The promotion and popularization of rubber dam technology has become an important direction for the development of the oral industry. In the "Notice on Issuing the National Medical Quality and Safety Improvement Goals for 2022" issued by the National Health Commission, "increasing the use rate of rubber dam isolation in root canal treatment" is listed as a national medical quality and safety improvement goal. The indicator stipulates that the use rate of rubber dam isolation in root canal treatment in medical institutions must reach the national average target value of 33%. At the same time, the practicing physician qualification examination also regards rubber dam isolation technology as an important part of the practical examination.

[0004] However, there are still many obstacles to the popularization of rubber dam. A survey of oral medical institutions in Hubei Province in 2022 showed that the total scores of the three dimensions of rubber dam isolation knowledge awareness rate, belief holding rate and behavior formation rate were 76.4%, 51.3% and 34.9% respectively.

[0005] The existing finished rubber dam stents are expensive, and public medical institutions need to purchase them in a centralized manner, which leads to difficulties in using rubber dams in primary hospitals and individual clinics. According to WS 506-2016 "Technical Operation Specifications for Disinfection and Sterilization of Oral Instruments", rubber dam stents are low-risk instruments and only require low-level disinfection. According to WS / T 367-2012 "Technical Specifications for Disinfection of Medical Institutions", physical and chemical disinfection methods take a long time, and the disinfection time of rubber dam stents in some institutions does not meet technical specifications.

[0006] The existing finished rubber dams are fixed in shape and cannot be personalized according to the patient's facial shape, oral conditions and actual clinical needs. This results in the rubber dam bracket not fitting the patient's facial shape, and the hard bracket compressing the patient's facial soft tissue, which not only leads to a poor treatment experience but may also cause soft tissue contusion. The rubber dam bracket is not coordinated with the size of the patient's oral cavity and the position of the affected teeth, resulting in excessive tension on the dam cloth during rubber dam isolation, making operation difficult.

[0007] The existing rubber dam stent retention device is mainly a spike structure, which has poor retention force. Doctors often cause the dam cloth to fall off during use, affecting the treatment process. The spike structure can easily puncture the dam cloth, causing leakage of flushing fluid during treatment. In severe cases, it can cause burns to the oral mucosa and face. Summary of the invention

[0008] In view of the above-mentioned defects in the prior art, the object of the present invention is to provide an easily self-made rubber dam stent and a manufacturing method and application thereof.

[0009] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] On the one hand, the present invention provides an easily self-made rubber dam bracket, including a filament, on which a first lower fixing part and a second lower fixing part are bent in sequence, and the filament turns in the same direction at the first lower fixing part and the second lower fixing part to form a U-shape; the first lower fixing part and the second lower fixing part divide the filament into a front filament segment, a middle filament segment, and a rear filament segment; the front filament segment is bent with a first upper fixing part, and the rear filament segment is bent with a second upper fixing part.

[0011] Further, the front wire segment is bent to form a first auxiliary fixing portion between the first upper fixing portion and the first lower fixing portion;

[0012] Specifically, the rear wire segment is bent to form a second auxiliary fixing portion between the second upper fixing portion and the second lower fixing portion.

[0013] Furthermore, the middle wire segment, the space between the first auxiliary fixing portion and the first lower fixing portion of the front wire segment, and the space between the second lower fixing portion and the second auxiliary fixing portion of the rear wire segment are all covered with a plastic support.

[0014] Furthermore, the angle between the front thread segment and the rear thread segment is 0°-15°.

[0015] Furthermore, the first upper fixing portion is arranged at the end of the front wire segment, and the second upper fixing portion is arranged at the end of the rear wire segment;

[0016] Specifically, the first upper fixing portion or the second upper fixing portion is a retaining ring hook.

[0017] Furthermore, the first lower fixing portion or the second lower fixing portion is at least one retaining ring.

[0018] Furthermore, the first auxiliary fixing portion or the second auxiliary fixing portion is convex, and the first auxiliary fixing portion and the second auxiliary fixing portion are arranged back to back.

[0019] Furthermore, the plastic support is a self-curing resin, and the filament is a dental wire.

[0020] In another aspect, the present invention provides a method for making a rubber dam stent that is easy to make by yourself, comprising the following steps:

[0021] Prepare a filament; bend a first lower fixing portion and a second lower fixing portion on the filament, the filament is turned in the same direction at the first lower fixing portion and the second lower fixing portion to form a U-shape, and the first lower fixing portion and the second lower fixing portion divide the filament into a front filament segment, a middle filament segment, and a rear filament segment;

[0022] A first upper fixing portion is bent at the front thread segment, and a first auxiliary fixing portion is bent between the first upper fixing portion and the first lower fixing portion of the front thread segment; a second upper fixing portion is bent at the rear thread segment, and a second auxiliary fixing portion is bent between the second upper fixing portion and the second lower fixing portion of the rear thread segment;

[0023] The plastic support is wrapped around the middle wire section, between the first auxiliary fixing part and the first lower fixing part, and between the second lower fixing part and the second auxiliary fixing part to obtain a rubber dam stent.

[0024] In a third aspect, the present invention uses the rubber dam stent described in the first aspect or the rubber dam stent prepared in the second aspect for dental treatment.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention can be completed by doctors without the need for procurement, is low-cost, and is easy to make. This allows grassroots hospitals and individual clinics to own it, and medical institutions are no longer constrained by price factors when using the rubber dam technology; large dental institutions can also own it in large quantities, thereby improving the disinfection standard of the rubber dam stent. In actual clinical work, the rubber dam stent will come into contact with a large amount of flushing fluid, causing bacterial contamination. Performing medium-level disinfection on the rubber dam stent as a moderately dangerous device helps reduce the risk of infectious disease transmission and helps improve treatment safety.

[0027] 2. The present invention can be personalized according to the patient's facial shape, oral conditions and actual clinical needs, so that the rubber dam bracket can better fit the patient's facial shape, improve the patient's treatment experience, and reduce the risk of soft tissue contusion; the rubber dam bracket is more coordinated with the patient's oral size and the position of the affected teeth, and the dam cloth tension is moderate during rubber dam isolation, reducing the difficulty of operation.

[0028] 3. The present invention uses a hook-shaped upper fixing part of a retaining ring, a lower fixing part of at least one retaining ring, and a protruding auxiliary fixing part as a retaining device, so that the retaining area is larger and the retaining force is stronger, thereby preventing the barrier cloth from falling off during use. In addition, the retaining ring is not easy to puncture the barrier cloth, and the protruding auxiliary fixing part prevents the barrier cloth from forming stress concentration at the retaining ring, thereby avoiding leakage during treatment.
