Description

The utility model relates to medicine and can be used in dentistry.

In therapeutic dentistry, any manipulations: surgical, orthopedic, restoration of hard tooth tissues or professional oral hygiene are associated with constant aspiration of oral fluid. The ingress of saliva reduces, for example, the quality of the restored surface. The key to the success of almost any dental treatment is the reliable isolation of the surgical field from the effects of various liquid media, bacteria and contact with the mucous membrane. One of the most effective working field isolation systems is a rubber dam type system, which has contraindications: latex allergy; diseases of the upper respiratory tract, difficulty in nasal breathing; psycho-emotional state of the patient; the presence of fixed orthodontic structures; increased gag reflex. Often in dental practice, dental tips for saliva ejectors RU FSZ 2009/04632 are used, a disposable dental saliva ejector versions: with a fixed tip, with a removable tip, with a flavored tip RU FSZ 2016 No. 2016/4053. Registration certificate of the Federal Service for Surveillance in Healthcare.

Known tip of the saliva ejector to protect the tongue and buccal mucosa, in which two curved tubes are connected in the form of a bifurcated main tube, the short part of which is bent at a right angle. The short part has a pad to protect the buccal mucosa, and the long part has a pad to protect the tongue. The long part of the main tube contains two bends located in mutually perpendicular planes. Both tubes end in cylinders 2 mm long, without internal holes, with the same diameters as the main tube. In front of the cylinders, on tubes with diameters smaller than the main tube, holes are made for suctioning saliva (RU 2118135, A61C 5/14, A61C 17/06, A61C 17/10, publ. 27.08.1998). The use of this tip reduces the evacuation of saliva and interferes with surgical procedures due to its design.

The main task that the proposed utility model is aimed at is to ensure uniform and constant aspiration of oral fluid and blood from the vestibule of the oral cavity, which leads to an increase in the quality of treatment.

The solution to this problem is ensured by the fact that the atraumatic tip of the saliva ejector for aspiration of oral fluid, blood and tooth dust from the vestibule of the oral cavity, including two interconnected tubes, contains tubes made of silicone, connected to a copper wire, fixed to each other in a T-shape, a hole with a diameter of 0.25 cm is made in the middle of the horizontal tube, while both ends of the horizontal tube, cauterized to the first sign of melting, are soldered by pressing, 16 holes with a diameter of 0.05 cm are made from the side of the hole in the horizontal tube, 8 - on one side and 8 on the other with respect to the vertical tube placed in the middle of the horizontal tube, with a distance of 1.5 cm from each other.

The use of the proposed handpiece for saliva ejection in surgical dentistry during various manipulations (extraction of teeth, removal of impacted and dystopic third molars of the lower jaw, bone grafting, dental implantation, resection of the root apex, excision of hypertrophied gums and removal of benign formations of the mucous membrane of the cavity, patchwork operations) provides adequate aspiration from the vestibule of the cavity, which allows to speed up the process of surgical manipulations, to provide high-quality visualization of the surgical field.

Improving the quality of treatment is ensured by ensuring the dryness of the surgical field; prevention of contamination of the working field with biological fluids; minimizing the likelihood of causing a gag reflex; reducing the risk of injury to the mucous membrane of the cheeks and lips; increase the service life of restorations; improving the working conditions of the doctor; availability due to the low cost of the utility model.

Due to the relatively rigid design (the presence of copper wire), the effect of retraction of the soft tissues of the lips and cheeks is also achieved. Due to this, the proposed tip for saliva ejector can be widely used in bone surgery, in particular in dental implantology and maxillofacial surgery.

The utility model is illustrated in FIG. 1, which shows a diagram of the tip, FIG. 2, which shows the isolation of the right corner of the jaw of the mouth, FIG. 3, which shows the fixation of the crown. In FIG. 4 and 5 show isolation with a U-tip for saliva aspiration.

In FIG. 1 shows a diagram of the saliva ejector tip, where

1 - the junction of the tip of the saliva ejector with a vacuum cleaner;

2 - copper wire of a vertical tube connected to the silicone of the main saliva ejector;

3 - silicone of the vertical tube of the main saliva ejector;

4 - the middle hole of the horizontal tube;

5 - bare wire of a vertical tube;

6 - the bare wire of the vertical tube;

7 - a wire of a vertical tube threaded through silicone;

8 - copper wire of a horizontal tube;

9 - silicone of a horizontal tube;

10 - holes of the horizontal tube;

11 - soldered ends of the horizontal tube.

Two tubes made of copper wire 2 and 8, connected to the silicone rod of the saliva ejector 3 and 9, are fixed to each other in a T-shape. One end of the horizontal tube 3 is the junction of the saliva ejector tip with the vacuum cleaner 1. In the middle of the horizontal tube 9 (the one that is placed in the vestibule of the oral cavity), a hole 4 with a diameter of 0.25 cm is made. Both ends of the horizontal tube 9 are cauterized until the first sign of melting, then are soldered by pressing, thereby soldered ends 11 are obtained. If that side of the horizontal tube 9, where hole 4 is made in the middle, is considered the bottom, 16 holes 10 with a diameter of 0.05 cm are made along the horizontal plane, 8 on one side and 8 on the other , spaced 1.5 cm apart.

On 1/4 of the vertical tube 3, a cut of silicone 3 is made with the copper wire 5 exposed. The exposed copper wire 2 is bent in the frontal plane until a right angle is formed, and it is turned in the distal direction in the horizontal plane until it intersects with the median side plane of the silicone tube 9 By measuring 0.5 cm, we make a bend in the frontal plane until a developed angle 6 is formed, thereby passing it through the silicone part 9 of the tube, first measuring 0.2 cm from the top of the silicone tube 3 and making small parallel holes 10 on the sides, through which the wire will have to be drawn. The longer part of the bare wire is bent upwards in the frontal plane until an acute angle 6 is formed.

After that, most of the bare wire of the vertically located saliva ejector, looking up and sideways, is pushed through the middle hole 4 of the horizontally located saliva ejector into the cavity of one half of the horizontal tube. And the second part of the bare wire, smaller, by pressing, is made through the middle hole into the cavity of the second half of the horizontal tube. After that, we press down on both ends of the horizontal tube in the frontal plane, thereby bending parallel to the T-shaped bare wire of the vertical saliva ejector. The bending process ends when the wire located in the cavity of the horizontal tube forms sharp corners at both ends, and the end of the silicone part of the vertical saliva ejector enters the cavity of the horizontal tube by 0.5 cm through the middle hole. When fixed in the oral cavity, the saliva aspiration tip acquires a U-shape.
