A ratchet (1) is provided, in particular a ratchet for surgical interventions or a dental ratchet, wherein the ratchet has a handle (2) and a pivot housing (4) arranged thereon, said pivot housing being a flat spiral (6). The spiral (6) is flexible and can be actuated such that the spiral (6) coils up in a plane that is oriented substantially vertically to the pivot axis D. The invention also relates to a torque transmission system which comprises a ratchet (1) and an implant driver. The implant driver has a first portion that is cylindrical and a second portion that is cylindrical or frustoconical, the second portion additionally having a receptacle for a medical tool, a surgical implant or any other object. In this way, an improved ratchet is obtained with which the torque to be applied can be applied to the implant driver in a metered manner. |
