device for the external fixation and / or extension and adjustment of the upper thoracic and cervical spine combined with fixation of the head

摘要

A device for externally fixing and/or extending and adjusting the upper dorsal vertebral column and cervical vertebral column, while at the same time fixing the head, has a holding device (10) that encloses the upper part of the body and that bears on linking braces (14; 114; 214) a ring (29) for fixing the head. The linking braces (14; 114; 214) are linked to the holding device (10) by means of a support bearing (13) and are linked to a transversal beam (22) that links the linking braces (14; 114; 214) in pairs by means of a fastening bearing (20; 121; 218). The transversal beam (22) is in turn linked to the fastening ring (29) by a fastening bearing (30). In order to improve such a device so that it is as comfortable as possible to wear and as easy to fix and adjust as possible, the linking braces (14; 114; 214) are spring-mounted on at least one of the support (13) or fastening bearings (20; 121; 218) and/or the linking braces (14; 114; 214) are inherently elastic in the vertical direction.
