Estimating the term…
A device for quickly stopping a medical or dental drilling tool includes a drilling tool having a body extending between a connection end and a working end and having a longitudinal extension along a longitudinal axis of the drilling tool. The drilling tool has a hollow outer shell in which a probe is held that can be moved along the longitudinal axis so that a part of the probe can be moved out of the shell through an opening. The probe is designed as an elongated pin, and its first end facing the connection end is held in the interior of the shell. An electromagnetic sensor for detecting relative movement between the shell and the probe is arranged along the longitudinal extension of the body. The drilling tool has a channel for a treatment fluid extending along the longitudinal axis.
A device for quickly stopping a medical or dental drilling tool comprising:
A method for using a medical or dental drilling tool that comprises a device for quickly stopping the drilling tool, a connection end for connecting to a drive, an abrasive working end for removing material, and a body extending between the connection end and the working end having a longitudinal extension extending along a longitudinal axis of the drilling tool, wherein the drilling tool has a hollow outer shell within which a first end of a probe pre-tensioned by a spring element is held, the probe being movable along the longitudinal axis relative to the outer shell such that at least a part of the probe is movable out of the outer shell through an opening in the outer shell at the working end, wherein the probe is designed as an elongated pin extending along the longitudinal axis with a second end facing the working end, and an electromagnetic sensor is positioned on the longitudinal extension for detecting a relative movement between the outer shell and the probe, the drilling tool having a channel for a treatment fluid extending along the longitudinal axis, the method comprising:
A method for using a medical or dental drilling tool that comprises a device for quickly stopping the drilling tool, a drive for the drilling tool, and a handpiece for connecting to the drilling tool, the device having a connection end for connecting to the drive, an abrasive working end for removing material, and a body extending between the connection end and the working end having a longitudinal extension extending along a longitudinal axis of the drilling tool, wherein the drilling tool has a hollow outer shell within which a first end of a probe pre-tensioned by a spring element is held, the probe being movable along the longitudinal axis relative to the outer shell such that at least a part of the probe is movable out of the outer shell through an opening in the outer shell at the working end, wherein the probe is designed as an elongated pin extending along the longitudinal axis with a second end facing the working end, and an electromagnetic sensor is positioned on the longitudinal extension for detecting a relative movement between the outer shell and the probe, further comprising a control and/or regulatory device for receiving a sensor signal generated by the electromagnetic sensor, the method comprising:
