Abstract

A torsional tightener (101) is used, inter alia, for anchoring elements (108) in implants (103) anchored in bone. The tightener is releasable at a previously set torque and comprises an electric motor (406), a unit (403) changing the speed down, and a torsional tightening part. For the purpose of achieving a well-defined set torque value, the energy supply circuit of the electric motor can be interrupted at a certain current value in the energy supply circuit. The interruption and the rotational energy in the rotating parts of the torsional tightener after interruption are designed to cause a torsional tightening moment which is situated at or near an optimal or desired point on the particular moment curve for the tightening in question. Alternatively, a disconnection part is used, which interrupts the tightening function at or near the desired point on the moment curve. <IMAGE>
