TUBULAR ADAPTER UNIT Russian patent published in 1998 - IPC

FIELD: medical engineering. SUBSTANCE: device has connective tubular coupling with axial slot and is tightened by means of tightening screw along the perimeter or other members. The coupling is used for receiving end of a tube. Ring-shaped attachment region is adjacent to one of the ends of the tubular coupling mainly having four equidistant threaded holes spaced along the perimeter for connective and adjustment screws (tightening screws) and ring-shaped ball thrust bearing for coming in engagement with semi-sphere of adjustment rod that enters the operation zone of the tightening screws with its protrusion shaped as polyhedral pyramid. To improve connection of tubular adapter unit and tubular member, the free end portion of the tubular coupling opposite to the attachment region is provided with plastic tightening collar on the internal ring-shaped surface. EFFECT: enhanced effectiveness in fixing module-type prostheses. 4 cl, 2 dwg , 2 tbl
