Workstand for experimental simulation of the backbone vertebrae fractures realigning

摘要

the framework consists of a superstructure (13) affixed to the base (12), the band fixing handles osiowymi (11) attached to the base (12),in which the chuck is mounted a motor (9) in the direction of the longitudinal axis of the spine (12) and anatomical anomalies during operation of the rear spine access and two pairs of bolts (8) placed in transpedikularnych przeznasadowo segment motor coils (9) the neighbouring vertebrae considered.it is characterised by the fact that each pair of bolts transpedikularnych (8) located on the opposite side of the circle, the testthe framework is attached to the supporting structure (13) through the angular displacement mechanism performing displacement bolts transpedikularnych (8) in planes parallel to the plane of the sagittal suture via two poprzeczek (7) and two flexible legs (4).the linkage (4) are driven by separate serwomechanizmy (2) secured to a framework supporting structure (13), with each pair of bolts transpedikularnych (8) has upper ends of bolts connected with another bar (7), and each bar (7) is connected with two ciu0119gnami (4).in addition, the position sensor is linear movements, especially transformatorowy transducer, connected to the recording and processing of data, which is the sensor is secured to the base (12) in the bottom (10) in a plane parallel to the plane of the u.s. u0142kowej segment motor (9).the other position is the angular displacement mechanism with displacement of transpedikularnych (8) in planes parallel to the plane of the sagittal suture via two poprzeczek (7) and the two legs attached to rigid przegubowo discs korbowych, ora with the sensor forces attached to the at least one rigid linkage.
