FIELD: medical engineering.
SUBSTANCE: device has body and supporting members. The body is designed as cylindrical tube. Supporting member is designed as a set of cylinders mounted so that confined longitudinal movements are allowed along guides in the device body. Threaded hole having cylindrical screw with slit is made in the middle part of device body. Spherical working part of the screw is directed inside of the device body in perpendicular to threaded hole and screw axis. Two pairs of diametrically opposed longitudinal through slots receiving the guide members fixed on supports are arranged on both sides apart of screw. Each support base has pins when turned outside and skewed grooves when turned inward. The grooves have are arranged along the screw axis and match it in diameter.
EFFECT: reduced risk of traumatic complications.
