摘要：
FIELD: medicine.SUBSTANCE: device for insertion and fixation of a metal implant in surgical management of traumatically injured pubic symphysis of the pelvic ring consists of a parallelepiped-shaped conductor one of narrow front sides of which is concaved with radius R3 and has round-angled borders skewed at 22°. A lower surface of the conductor has a groove configured as a flat ring segment and limited by arches of two circles with the centre common with that of the concaved front side of the conductor with radius R3. Radiuses of the two circles - smaller - R2 and greater - R1, fit those of a metal implant plate temporary used during the surgical intervention. A groove width equals to that of the metal implant plate. A groove depth makes 0.4 of a thickness of the metal implant plate. At the intersection of a long symmetry plane of the conductor and the mean radius R of the annular groove, there is a through threaded hole with a buried captive screw temporary securing the metal implant plate to the conductor before the surgical intervention. The threaded hole has a cylindrical slot enclosing a screw head flush with an upper surface of the conductor. On the upper surface of the conductor on radius R fitting the mean radius R of the annular groove, there are two cylinders configured integrated with the conductor body and mirror-symmetrical, in relation to the long symmetry plane of the conductor the cylinders have an external diameter of 14 mm and a height of 28 mm on their side surfaces, the cylinders have on all height facing flat cuts spaced at 8.5 mm. A distance of the cylinder axes of the conductor equals to that of the axes of the two holes formed on the metal implant plate and used to bury fixing screws used to secure the metal implant plate to the injured pubic symphysis of the pelvic ring during the surgical intervention, and makes 20 mm. Along the axes, the cylinders of the conductor have through holes 9 mm in diameter used to alternately enclose a detachabl
