Surgical retraction instruments
The instruments are intended for widening wounds, cavities, passages and pushing back organs that are not subjected to surgical intervention to protect them from accidental trauma.It is used to spread the wound edges formed by low-elastic soft tissues or ribs, to keep the wound edges in a given fixed position for a long time without the assistance of a surgical assistant, for adjustable spreading of the wound edges by a given amount.The basis of the slatted wound spreaders are two parallel slats, located at a distance from each other. One working part of the wound spreader is rigidly fixed at one end of the slats.
The other part is movable and slides on the rail due to the end slots. Fixation of the mobile part of the retractor after the wound edges are separated is due to the friction force with a slight "skewing" of the windowed slit.
