The proposal is for a holding element (,) which can be screwed into the internally threaded bore (,) of the implant (,) even during production of the latter and can thus be used to grip or hold the implant for the following production phases. Furthermore, the holding element (,) serves to fix an implant (,), which is screwed thereto, inside an ampoule (,) and for the application of a screwing-in tool for implantation. The particular feature of the ampoule (,) lies in the fact that it has a large-area, lateral cutout (,) in the casing and also a fixing part (,) for accommodating the holding element (,) in a clamped manner. The implant (,) can thus be pulled laterally out of the ampoule (,). The devices facilitate handling of the implant (,) during production and insertion into the bone.

Retaining element for an implant and ampoule for preserving said implant

The torque wrench (1) comprises a torque instrument (10) which is known per se--in the present case a ratchet instrument--as well as a torque indicator (40) which can be attached thereto. The torque indicator (40) possesses a sleeve-shaped support (41) which can be pushed onto the handle (12) of the torque instrument (10) and on which a linearly elastic bending rod (51) is fastened. Upon operation, the force (F) is exerted upon the free end of the bending rod (51) and the torque generated is displayed on a graduation (48). At its very front the support (41) possesses a non-rotationally symmetrical insertion zone (42) which receives the transition region (121) of the handle (12) in a manner fixed against rotation. The principal advantages of the torque wrench (1) are its dismantlability and the combination possibilities. The display accuracy of the torque indicator (40) is checked using a special test device.
