Definitions
- the invention relates to a medical or dental rotating instrument, in particular a drill, a milling cutter, a file or the like with a shaft for arranging the instrument in a drive part and an instrument part adjoining the shaft.
- Such instruments are used in the medical field, both human and veterinary, and in the dental field for micro-bone surgery and dental treatment.
- it can be Tooth root canal instruments and implant drills or milling cutters for introducing drill studs into bone substance, in particular for dental implants.
- Such instruments are loaded during use in a manner that allows only a limited number of uses of each individual instrument. If this number of permissible uses is exceeded, z. B. the risk of breakage of the instrument part.
- tooth root canal instruments but also to implant drills or milling cutters.
- the cutting edge of the instrument part ie. H. of the drilling or milling tool part is particularly important. Since the wear of these cutting edges is relatively high, especially when machining the outer hard bone layer, and the extent of the wear is difficult to determine, the permissible number of uses of each individual instrument must be limited. For implant drills or milling cutters, this permissible number is, for example, 12, for tooth root canal instruments between 6 and 8.
- the object underlying the invention is therefore to create an instrument of the type mentioned at the outset, which is designed in such a way that the number of uses of the instrument can be recognized in a simple manner. This object is achieved by the training specified in claim 1.
- one of the markings provided on the shaft can be removed after each use, so that the number of markings still remaining indicates the number of possible uses and after the last marker has been removed, the instrument can no longer be used.
- the manufacturer can therefore provide markings on each instrument in a number that corresponds to the maximum recommended number of uses, so that the removal of the last marking can be regarded as a sign of the consumption of the instrument. Since the markings are provided on the instrument itself, incorrect assignment of uses to other instruments is excluded.
- the single figure shows the embodiment of the instrument according to the invention in a side view.
- the embodiment of the instrument according to the invention shown in the drawing is an implant drill, but it goes without saying that the design according to the invention can also be provided on other rotating instruments, such as drilling or milling tools, files in the medical, dental or dental field, if the use or the use of the individual instruments is limited in number due to wear-related causes.
- the implant drill 1 shown in the drawing has an instrument part or working area 2, on the front side of which there are cutting edges 3 and which is provided with grooves 4 for the removal of the removed chips.
- the working area 2 of the implant drill 1 is followed by a generally cylindrical shaft 5, which is used to clamp the implant drill 1 in a drive part. This shaft 5 often carries etched or eroded information about its diameter, its length, the manufacturer, etc.
- markings 6 are made along the shaft in the form of transverse lines, the number of which corresponds to the maximum recommended number of uses of the implant drill 1. These markings 6 can also be provided in another form, for example in the form of dots.
- An unused implant drill 1 thus has as many markings 6 as the manufacturer of the implant drill 1 recommends as the maximum number of uses. This is 12, for example.
- the markings 6 can be designed in a wide variety of forms, provided that they can be removed after each use. They can thus be hidden, removed, filled in or removed. An appropriate abrasive tool can be used for this. Examples of the formation of the markings 6 are etching, erosion or application, in particular ink application.
- the implant drill 1 is used, one of the markings 6 is removed. This can expediently take place by means of a rubber polisher, which is supplied by the manufacturer of the implant drill 1. This can also be a rubber polisher that is commonly used in a dental practice. In the case of color markings, they can also be cut with the edge of a knife be removed with your fingernail. After the last marking 6 has been removed, the implant drill 1 is regarded as blunt and thus worn out and sorted out.
