Abstract

FIELD: medical engineering.

SUBSTANCE: device has shank, working part having end guide connected to the shank by means of neck member and cutting depth restrictor. The restrictor has increased diameter and is placed between the working part and neck member. Helical groove is available on the working part and neck member for discharging cutting products. The neck member has low strength zone. The cutting depth restrictor repeats working part shape. Another embodiment has shank and working part connected to the shank by means of neck member. Cutting depth restrictor is placed between the working part and neck member of increased diameter. The cutting depth restrictor repeats working part shape and has maximum size being in inverse proportional relation to neck length.

EFFECT: improved conditions of engagement with tissues under treatment.

5 cl

Description

Зубоврачебный инструмент относится к медицинской технике и может быть использован в стоматологии и ортопедии для обработки тканей всех видов.Dental instrument refers to medical equipment and can be used in dentistry and orthopedics for the treatment of tissues of all kinds.

Известен зубоврачебный инструмент по описанию к а.с. СССР №176038, А 61 С 3/02, 1965, содержащий хвостовик и рабочую часть, соединенную с хвостовиком посредством шейки.Known dental instrument for the description of A. with. USSR No. 176038, A 61 C 3/02, 1965, containing a shank and a working part connected to the shank by the neck.

Недостатком известного инструмента является неудобство работы с ним, а также невозможность его применения в глубоких полостях.A disadvantage of the known tool is the inconvenience of working with it, as well as the impossibility of its use in deep cavities.

Более близким аналогом к предложенным инструментам является зубоврачебный инструмент по описанию к US 2453696 А, 16.11.1948, содержащий хвостовик, рабочую часть с торцевым направителем, которая соединена с хвостовиком посредством шейки, и ограничитель глубины резания увеличенного диаметра, размещенный между рабочей частью и шейкой.A closer analogue to the proposed tools is a dental tool according to the description of US 2453696 A, 11.16.1948, comprising a shank, a working part with an end guide that is connected to the shank by means of a neck, and an oversized cutting depth limiter placed between the working part and the neck.

Технический результат настоящего изобретения заключается в улучшенном взаимодействии с обрабатываемыми тканями его рабочей части.The technical result of the present invention consists in improved interaction with the processed tissues of its working part.

Сущность изобретения выражается совокупностью существенных признаков, в которой зубоврачебный инструмент, содержащий хвостовик, рабочую часть с торцевым направителем, которая соединена с хвостовиком посредством шейки, и ограничитель глубины резания увеличенного диаметра, размещенный между рабочей частью и шейкой, отличается от ближайшего аналога тем, что имеет винтовую канавку для отвода продуктов резания, которая расположена на ограничителе глубины резания и на шейке, выполненной с участком пониженной прочности, при этом ограничитель глубины резания повторяет форму рабочей части.The invention is expressed by a combination of essential features, in which a dental instrument containing a shank, a working part with an end guide that is connected to the shank by means of a neck, and an oversized cutting depth limiter located between the working part and the neck, differs from the closest analogue in that it has a helical groove for removal of cutting products, which is located on the limiter of the depth of cut and on the neck, made with a section of reduced strength, while limiting l the depth of cut follows the shape of the working part.

Вариант зубоврачебного инструмента содержит хвостовик и рабочую часть, соединенную с хвостовиком посредством шейки, отличается от ближайшего аналога тем, что между рабочей частью и шейкой расположен ограничитель глубины резания увеличенного диаметра, повторяющий форму рабочей части, при этом максимальный размер ограничителя глубины резания обратно пропорционален длине шейки.A variant of a dental instrument contains a shank and a working part connected to the shank by means of a neck, differs from the closest analogue in that there is an oversized cutting depth limiter between the working part and the neck, repeating the shape of the working part, while the maximum size of the cutting depth limiter is inversely proportional to the length of the neck .

В частных случаях своего выполнения или использования зубоврачебный инструмент может содержать рабочую часть, снабженную торцевым направителем, винтовую канавку для отвода продуктов резания, которая расположена на ограничителе глубины резания и на шейке, а также шейку с участком с пониженной прочностью.In special cases of its implementation or use, the dental tool may contain a working part equipped with an end guide, a helical groove for removal of cutting products, which is located on the limiter of the cutting depth and on the neck, as well as a neck with a section with reduced strength.

Claims

1. A dental instrument containing a shank, a working part with an end guide connected to the shank by means of a neck, and an oversized cutting depth limiter located between the working part and the neck, characterized in that it has a helical groove for removal of cutting products, which is located on the limiter the depth of cut and on the neck, made with a section of reduced strength, while the limiter of the depth of cut follows the shape of the working part.

2. A dental instrument containing a shank and a working part connected to the shank by means of a neck, characterized in that between the working part and the neck there is an oversized cutting depth limiter that repeats the shape of the working part, while the maximum size of the cutting depth limiter is inversely proportional to the length of the neck.

3. The dental instrument according to claim 2, characterized in that the working part is equipped with an end guide.

4. The dental instrument according to claim 2 or 3, characterized in that it has a helical groove for removal of cutting products, which is located on the limiter of the depth of cut and on the neck.

5. The dental instrument according to claim 2, 3, or 4, characterized in that the neck has a section with reduced strength.
