Description

The utility model relates to instruments for implantation, in particular to holders of dental screwdrivers, sockets, keys and similar instruments having small dimensions and used for fixing dentures/implants and their components in place.

Structurally, a dental screwdriver (head, wrench, similar tool) is a tip with a specific configuration suitable for the selected implantation / prosthetic system, this component can have a different length, for example, in a number of products from brands such as ADM, BoneTrust, KaVo, Geistlich, Hu-Friedy, Alpha Bio, etc., have the following options:

ultrashort - about 12.7 mm long;

universal short - 18.5 mm;

universal ultra-long - 23.5 mm;

ultra-long - 33.1 mm.

Versatile tools allow you to work with extension cords, torque grips or hands. The choice depends on the tasks and the position of the serviced unit in the oral cavity.

The smallest screwdrivers are usually used only in manual mode, they are as compact as possible and allow you to get into hard-to-reach areas, for example, to get to the molars at the ends of rows deep in the mouth, however, there is a high risk that a small screwdriver will slip out of the surgeon’s hand and cause significant harm. patient, up to death if inhaled.

Thus, in practice, as a rule, the holder of a dental screwdriver is (in addition to the hand of the surgeon - discussed above) an extension cord or a dynamometric handle (see, for example, ABUTMENTY.RU [https://abatmenty.ru/ - Electronic resource]. - Mode access: https://abatmenty.ru/spravochnik/otverdki, free access - (11/28/2022).

The disadvantages of such holders include the limited scope of their application, due to the impossibility of accurately hitting the instrument and/or ensuring the required orientation of the instrument in hard-to-reach areas, for example, in the area of molars at the ends of the rows in the depths of the mouth.

The closest to the claimed technical solution - the prototype - is the holder of the Ortho Easy F dental screwdriver of the German company Forestadent, made in the form of a compact cylindrical handle and placed inside the handle and mechanically connected to it with a tip for placing a screwdriver in it (A ORTHODONYIC COMPANY [https: // breket.pro/ - Electronic resource] - Access mode: https://breket.pro/catalog/mikroimplanty/OrmoEasy/derzhatel-otvertki-s-krutiashchim-momentom-orto-izi-1299-0007/, free access - 28.11 .2022). The compact design of the prototype, to a certain extent, allows for an accurate hit and / or the required orientation of the tool in hard-to-reach areas.

The disadvantages of the prototype include the insufficient safety of its use, due to the high probability of the holder slipping out of the surgeon's hand together with the screwdriver and, given the small size of both the holder and the screwdriver, causing significant harm to the patient, up to death if it enters the respiratory tract.

In view of the foregoing, the identified problem is to eliminate the negative consequences when the holder/screwdriver slips out of the surgeon's hand during the operation, while ensuring an accurate hit and/or the required orientation of the instrument in hard-to-reach areas.

EFFECT: improved safety.

The identified problem is solved, and the claimed technical result is achieved by the fact that in the holder of a dental screwdriver containing a handle and a tip connected to it for placing a screwdriver in it, the tip is made of an annular shape from an elastically deformable polymer, and its inner diameter is smaller than the diameter of the screwdriver and is made with the possibility of providing interference fit in the cavity of the tip of a dental screwdriver and its retention during surgical procedures in the patient's oral cavity, and the handle is made in the form of a bendable rod, one of the ends attached to the outer generatrix of the tip, and the handle is made with the possibility of bending while maintaining the given curved shape.

The utility model is illustrated by images showing:

in fig. 1 - example I of the execution of the holder, top view;

in fig. 2 - example I of the execution of an arbitrarily curved holder, side view;

in fig. 3 - dental screwdriver in the holder;

in fig. 4 - example II execution of the holder, top view;

in fig. 5 - example II execution of an arbitrarily curved holder, side view;

in fig. 6 is a section A-A in FIG. 2 for example III of the execution of the holder.

According to the utility model, the holder of a dental screwdriver contains a handle 1 and a tip 2 connected to it for placing a screwdriver 3 in the latter. within the elastic deformation of the tip in the diametrical direction. This design provides an interference fit in the cavity of the tip 2 of the dental screwdriver 3 (Fig. 3) and its reliable retention during surgical procedures in the patient's oral cavity.

The handle 1 is made in the form of a bendable rod (Fig. 1, 2, 4, 5), one of the ends attached to the outer generatrix of the annular tip 2. given a curved shape. The bending of the handle 1 is necessary to form the configuration required for bringing the dental screwdriver 3 into hard-to-reach places in the patient's oral cavity. Such bending of the handle 1 can be provided, including, but not limited to, the three examples below.

Example I. It is possible to use a special material used, for example, in the manufacture of children's bent cutlery from CANPOL (CANPOL BABIES [https://canpolbabies.com/ru_RU - Electronic resource]. - Access mode: https://canpolbabies.com/ ru_RU/canpol-babies-flexible-cutlery-p831716, free access-11/28/2022).

Example II. the bent rod (handle 1) can be made of a rigid polymer with a tubular cross section having a corrugated section 4 between the end adjacent to the tip 2 and the opposite end. The handle 1 can have either one corrugated section 4 (Fig. 4, 5), or several - for the convenience of forming a complexly curved profile. The operability of such a design in mass use has been proven by its use in a technical solution for a different purpose - bendable cocktail tubes (see, for example, YuO [http://www.krepplast.ru/ - Electronic resource]. - Access mode: http://www. krepplast./category/trubochki-dlya-kokteylya-razmeshivateli-shpazhki-dlya-kanape/trubochka-c-izgibom-frukti-24-sm-19878-100-sht-v-upakovke-10-upakovok-v-korobe/, free access - 11/28/2022).

Example III. The bent rod (handle 1) can be made of an elastic polymer with a tubular cross section and equipped with a plastically deformable insert 5, for example, a piece of bent wire (wire bendability in the context of this application means the ability of the wire to bend while maintaining the given curved shape), fixed (for example inserted with an interference fit) inside the tubular rod. This design of the handle 1 will fully ensure its bending to the extent necessary and sufficient to achieve the claimed technical result of the dental screwdriver holder.

Next, we will consider the practical implementation of the claimed technical solution in the scope of the above examples, in which the claimed design of the dental screwdriver holder was formed for the line of AZDENT tools with a diameter of 1.2 to 1.4 mm.

Example I. As handle 1, a rod-shaped spoon from CANPOL was used (CANPOL BABIES [https://canpolbabies.com/ru_RU - Electronic resource]. - Access mode: https://canpolbabies.com/ru_RU/canpol- babies-flexible-cutlery-p831716, free access - 11/28/2022). As an annular tip 2, a piece of medical silicone capillary with an inner diameter of 1 mm, a wall thickness of 2 mm and a length of 7 mm was used, manufactured by ITEK LLC (KORP ITEK [https://intekcorp.ru/ - Electronic resource]. - Access mode: https://itekcorp.ru/catalog/meditsinskie-trubki/, free access - 11/28/2022). The connection of the indicated elements into a structure in accordance with the formula of the utility model and the images of Fig. 1, 2 was carried out by means of spot ultrasonic welding along the contour of the joint of the indicated elements with a manual ultrasonic welding machine of the Chinese company OKSULTRASONIC model OKS-DHJ-300usW.

Example II. As handle 1, a cocktail tube 5 × 240000 "KREPPAK SERVICE" (South Ossetia [http://www.krepplast.ru/ - Electronic resource]) was used. - Access mode: http://www.krepplast./category/trubochki-dlya -kokteylya-razmeshivateli-shpazhki-dlya-kanape/trubochka-c-izgibom-frukti-24-sm-19878-100-sht-v-upakovke-10-upakovok-v-korobe/, free access - 11/28/2022). As an annular tip 2, a piece of medical silicone capillary with an inner diameter of 1 mm, a wall thickness of 2 mm and a length of 7 mm was used, manufactured by ITEK LLC (KORP ITEK [https://intekcorp.ru/ - Electronic resource]. - Access mode: https://itekcorp.ru/catalog/meditsinskie-trubki/, free access - 11/28/2022). The connection of the indicated elements into a structure in accordance with the formula of the utility model and the images of Fig. 4, 5 was carried out by spot ultrasonic welding along the contour of the joint of the indicated elements with a manual ultrasonic welding machine of the Chinese company OKSULTRASONIC model OKS-DHJ-300usW.

Example III. Handle 1 was a segment of a medical silicone capillary with an inner diameter of 1 mm, a wall thickness of 2 mm and a length of 200 mm manufactured by ITEK LLC (KORP ITEK [https://intekcorp.ru/ - Electronic resource]. - Access mode: https ://itekcorp.ru/catalog/meditsinskie-trubki/, free access - 11/28/2022). A plastically deformable insert is introduced inside the capillary “with an interference fit” - a corresponding piece of wire made of food-grade aluminum grade AD1 with a diameter of 1.2 mm GOST 14838-78 manufactured by Sinara SP LLC (SINARA [https://sinara.pro/ - Electronic resource]. - Access mode: https://sinara.pro/alyuminievyy-prokat/alyuminievaya-provoloka/alyuminievaya-provoloka-adl/provoloka-adl-2-28.11.2022). As an annular tip 2, a piece of medical silicone capillary with an inner diameter of 1 mm, a wall thickness of 2 mm and a length of 7 mm was used, manufactured by ITEK LLC (KORP ITEK [https://intekcorp.ru/ - Electronic resource]. - Access mode: https://itekcorp.ru/catalog/meditsinskie-trubki/, free access - 11/28/2022). The connection of the indicated elements into a structure in accordance with the formula of the utility model and the images of Fig. 1, 2, 6 was carried out by spot ultrasonic welding along the contour of the joint of the indicated elements with a manual ultrasonic welding machine of the Chinese company OKSULTRASONIC model OKS-DHJ-300usW.

Each of the above examples of the dental screwdriver holder was tested using AZDENT screwdrivers with a diameter of 1.2 to 1.4 mm. In this case, the surgeon held and guided the holder with a pre-curved handle 1 with one hand, and rotated the screwdriver in place with the other hand. In all cases, the screwdrivers were securely held and had no axial displacement in the tip 2 of the holder, while the manual rotation of the screwdriver in the tip 2 was carried out quite freely. In case of intentional (experimental imitation of negligence and/or other emergency situation) release of the handle 1 by the surgeon, due to the configuration/bending of the latter, the holder lay down on the front/inside the mouth surface without causing discomfort/harm to the patient and was not able to penetrate into the patient's airways.

The foregoing allows us to conclude that the identified problem - the elimination of negative consequences when the holder/screwdriver slips out of the surgeon's hand during the operation while ensuring an accurate hit and / or the required orientation of the instrument in hard-to-reach areas - has been solved, and the claimed technical result - increased safety - has been achieved. .
