Embodiment Construction

[0031] In order to be able to increase the range of movement of the C-brace, known guidance concepts are modified. Instead of stationary rollers, the C-bar is supported by means of a cage guide arrangement. As a result, the necessary overlap between the C-arm and the C-arm bearing assembly can be reduced and thus the range of movement can be increased.

[0032] Unlike hitherto known rolling elements (rollers, balls, needles) of the guide are no longer fixedly mounted in the C-bow support assembly, but the cage guide assembly (= rolling element cage plus Rolling body) moves in the C-bow support assembly according to the cage guiding principle of 1:2. The transported support elements are thus no longer mounted in a fixed position, but are positioned automatically within the C-brace support assembly. The result is a telescopically guided movement of the C-bow. figure 1 Explain this principle in detail.

Abstract

The invention relates to a supporting device for a C-shaped bow frame of an X-ray imager. The device comprises a C-bow frame (1), a C-bow support assembly (2) and at least one cage movably arranged between the C-bow frame (1) and the C-bow support assembly (2) The guide assembly (3), the C-bow frame (1) is movably supported on the cage guide assembly (3) in the C-bow support assembly (2), wherein the cage guide assembly (3) includes A plurality of rolling elements (9, 12) and at least one rolling element cage (10). The invention likewise relates to an x-ray imager with a C-arm support according to the invention. The invention offers the advantage that, due to the small overlap between the C-arm (1) and the C-arm bearing assembly (2), a greater rotation about the isocenter is possible.

Description

technical field [0001] The present invention relates to a device for movably supporting a C-bow in a C-bow support assembly by means of a cage guide, and to a device comprising a C-bow movable within the C-brace support assembly rack of X-ray imagers. Background technique [0002] The X-ray imager is used not only in X-ray fluoroscopy but also in X-ray photography. Here, the object is transmitted by the X-ray beam emitted by the X-ray emitter before it is attenuated by the object and hits the X-ray detector. There are many different embodiments of x-ray imaging machines, in particular also x-ray machines with C-arms. [0003] An example of a C-brace X-ray apparatus designed as a ceiling-mounted apparatus is described in the published document DE 10109754A1. An X-ray emitter and an X-ray detector are fixed at the ends of the C-shaped bow frame. The C-arm is movably mounted and can be rotated around the patient by means of a drive. Here, the C-bracket is moved along its o...
