DE102004032558A1 - Dental anatomical college flat tweezers, has two flat, circular functional ends which provide coplanar contact surface of defined size when gripping tweezers, where inner surfaces of ends have corrugation or groove - Google Patents

Abstract

The tweezers has arms with two flat functional ends (1) which provide a coplanar contact surface of defined size when gripping the tweezers. The functional ends are circular in shape and have a diameter of approximately 3 millimeter (mm), where inner surfaces of the ends have a corrugation or groove.

Description

• -anatomische Pinzetten
• -chirurgische Pinzetten
• -spezielle Pinzetten

The dental forceps are divided into

• -anatomical forceps
• surgical forceps
• special tweezers

The surgical forceps are used in surgical procedures. Both tweezer arms are straight and are at both function ends provided with a small jag. These prongs allow one firm grip of the tissue to be grasped with the tweezers.

The anatomical tweezers is the standard tweezers at the general dental Activity. Your both arms are either straight or as college tweezers about 1.5 cm over before the end the area the arms are bent at an angle of about 120 °. The real thing Functional end of the tweezers is tapered, straight and at the Fluted inside of both ends.

The anatomical tweezers as standard tweezers in the dental Treatment is worked as college tweezers and is because of the aimed handiness relatively easy and graceful.

The Special tweezers are powerful Holding or grip tweezers that are able to absorb larger forces or exercise to be able to. They are for very specific applications, e.g. as holding tweezers for implants especially for the object to be made.

she are therefore correspondingly heavier and more massive.

The Anatomical college tweezers as standard tweezers in dentistry Has inherent design disadvantages in your grip and hold function special grip and holding applications. The improvement of this typical type Disadvantages are the subject of innovation.

to dental activity belongs et al the root canal treatment.

at Root canal treatment becomes the root canal lumen with special Files and drills for the root canal filling to be made edited. The cleaning and the prepared root canal is dried with approx. 35mm long and ca.0,2 - 1,5mm thin Paper points. The final definitive root canal filling carried out by means of a mechanically driven spiral lentulos, the root filling paste in the root canal einrotiert and one or more about 35mm long and about 0.2 - 1.5mm thin Gutta-percha points using anatomical college tweezers be introduced by hand into the root canal lumen. Among the cramped conditions the oral cavity has the anatomical college tweezers due to their above described Shape design-related disadvantages in the grip of these for root canal treatment required Gutta-percha and paper points. This is due to the material especially for the gutta-percha points.

Of the reason for The low grip when holding the tips is the low area with the functional ends of the anatomical college tweezers these Can hold tips, especially with different brackets between holding object and Tweezers.

In order to improve the grip of these tips, the shape of the functional ends must be changed. This is the subject of innovation. Instead of letting the functional ends taper sharply as described above, the functional end is flat and circular in diameter of about 3mm designed so that the two ends in contact with the entire circular surface have contact (see drawing ( 1 )). The circular inner surface is grooved or roughened to increase the grip. The advantage is the higher grip, which is especially at different grip angles between the holding object and the functional ends of the tweezer arms. At the same time, this redesign of the tweezer ends maintains the easy handling of the anatomical college tweezers, since the change in shape only affects the ends of the tweezers and therefore does not result in a significantly higher weight of the material.

Claims (4)

Dental anatomical college tweezers, characterized in that their two functional ends ( 1 ) are designed flat and thereby a plane-parallel contact surface of defined size is made possible when accessing the tweezers.
