Problems solved by technology

However, it has proven to be disadvantageous that this involves additional manually performed work steps which always take some time
In addition, it is obviously problematic that the adjustment cannot be carried out with the instrument used for subsequent treatment, because the adjustment system is usually not sterile or sterile and accordingly during the adjustment process the instrument and Loss of sterility of electric motors (but especially tools)
That is to say, in the adjustment systems used up to now, which are generally independent devices, there is always finally a certain insecurity in terms of the torque actually applied subsequently

Embodiment Construction

[0022] figure 1 A device according to the invention is shown comprising a dental instrument with a marking 1 and a supply unit / control unit 10 arranged for the supply and control of this instrument 1 . The dental instrument 1 has an electric motor 2 as a drive unit, wherein a front handle 3 is mounted on the electric motor 2 and has a head 4 comprising means for receiving a tool 5 . Near the head 4 on the front handle 3 there can be a light source 6 forming instrument lighting for illuminating the treatment site and also an outlet 7 for delivering air and / or water.

[0023] The instrument 1 is connected to a supply unit / control unit 10 by means of a supply hose 8 , wherein the medium required for the operation of the instrument 1 , in particular electric current, is supplied via the supply hose 8 . However, air, water and / or light can also be conveyed via the hose 8 .

[0024] Furthermore, the central component for controlling the electric motor 2 is the control unit 11 loca...

Abstract

The method involves operating a medical instrument (1) during a calibration step of an electric motor (2) with a power tool (5) in one operating point. The generator voltage, the speed and the open-circuit current of the electric motor are detected based on the operating point. A load friction torque for the medical instrument, which is taken into account as a correction factor in the driving of the motor during the subsequent operation of the medical instrument, is calculated based on the determined parameters. An independent claim is included for a dental system.

Description

technical field [0001] The invention relates to a method for operating an electric motor of a medical device having means for receiving a tool driven by said electric motor. Medical devices are in particular dental surgical devices or so-called endodontic devices. The invention also relates to a dental device with a corresponding instrument. Background technique [0002] Dental instruments generally differ in the type of drive used in the instrument. Although instruments with turbine drives were mainly used earlier, instruments with electric drives are also increasingly being used, since in such drives the rotational speeds required for the corresponding treatment in dental practice can also be achieved at the same time. An advantage of a dental instrument with an electric drive is also that the rotational speed and the torque can be precisely adjusted by correspondingly controlling the electric motor. [0003] Especially for dental instruments used in implant surgery, it...
