The invention relates to a method for determining an optimal frequency of an oscillating movement of a force-accelerated projectile of an intracorporeal pneumatic lithotripsy apparatus, including the following steps: repeatedly accelerating the projectile from a first proximal stop of an acceleration path to a second distal stop, and from the second stop to the first stop, wherein a piezo element is arranged between a proximally arranged counter bearing and a distally arranged horn and is mechanically coupled to the counter bearing and to the horn, and the horn has a distally arranged sonotrode, wherein the acceleration path is arranged in the interior of the counter bearing and of the horn and the first stop is arranged at a distal end of the counter bearing and the second stop is arranged at a distal end of the horn, detecting an electrical signal from the piezo element caused by a tremor at the first stop and/or the second stop as a result of the projectile; and using the detected electrical signal to control a medium which generates the force and which is used to accelerate the projectile from the first stop of the acceleration path to the second stop, and from the second stop to the first stop.

The disclosure relates to a holding device () for medical instruments () having a proximal base () for mounting on a frame (), said base comprising a first joint (), having a distal instrument holder () which comprises a second joint (), having at least two sliding elements () between the base () and the instrument holder (), and having at least two clamping elements () which can be actuated by at least one transfer element (), which can be operated jointly in a clamped stated and a released state, and which are designed to lock joints of the holding device () in the clamped state, wherein the at least two sliding elements () form a sliding joint () and can be displaced translationally relative to each other along a longitudinal axis (), and wherein the at least two sliding elements () are telescopable relative to each other and coupled non-rotationally with each other. The disclosure also relates to a medical system, a use of a holding device, as well as a method for positioning a medical instrument.
