Abstract: The present embodiments relate to a displacement apparatus for a C-arm arranged on a trolley. The displacement apparatus includes at least a first and at least a second guide element arranged in a plane, whereby the first and second guide elements are arranged at right angles to one another, a first displacement device which can be moved along the first guide element, and a second displacement device, which can be moved along the second guide element. A linking device connects the first and second displacement device in such a way that any movement of the first displacement device will result in the second displacement device being moved along the second guide element. This avoids the possibility of any jamming which may arise as a consequence of the leverage forces generated when a C-arm is moved.

Abstract: A retaining apparatus having a fastening element for fastening to a device, a first retaining element which is arranged on the fastening element in such a manner that it can be pivoted about a first axis, and a second retaining element which is arranged in such a manner that it can be pivoted about a second axis that is oriented perpendicular to the first axis and is designed to retain a flexible connecting element such that it can be moved forwards and backwards ensures a definable profile of the connecting element with little mechanical loading. A medical device, in particular in the form of a C-arc X-ray device, is provided with this retaining apparatus in a particularly advantageous manner.

Abstract: A movement system for a C-arm. The movement system comprises at least one first guide element arranged in a plane, a movement device arranged to allow movement along the first guide element as well as a first motion link rotatable around a first axis of rotation standing at right angles to the plane. The movement device is connected rotatably to the first motion link to a second axis of rotation standing at right angles to the plane such that a movement of the movement device along the first guide element causes the second axis of rotation to be moved on a circular track around the first axis of rotation. The advantage of this is that the arm is prevented from jamming as a result of leverages during movement of a C-arm.

Abstract: A lithotripsy apparatus (2) comprises an X-ray system (3), with an isocentre (1) arranged in a mid-plane of the X-ray system (3), and a shockwave head (6) that can be oriented with respect to the isocentre (1) and is mounted on a support device (8). A particularly simple and stable mechanism for adjusting the shockwave head is obtained in which the support device (8) has a first adjustment unit (20) that can be moved linearly for horizontal adjustment of the shockwave head (6), a second adjustment unit (24) that can be moved linearly for adjusting the height of the shockwave head (6), and a rotary adjustment unit (22) for rotating the shockwave head (6).

Abstract: A modular support structure for a device consists of module components of different module component types. The number of different module component types may be restricted in order to enable a particularly simple construction of the support structure. The module component types comprise a plate-like sheet and a u-shaped bent sheet having link plates arranged on both sides.
