FIELD: medical engineering.
SUBSTANCE: device has working surface formed by plates. The plates are movable and fixed and have working surface shaped as semi-circles. Semi-circle surface has curvature in longitudinal direction equal to 12-13° and curved as grips from internal side. The working surface is connected to the pulling uprights via fixed plates. Each of fixed plates has a handle. The movable plates are fixable relative to the fixed plates.
EFFECT: increased operation access zone in required direction; wide range of functional applications.
