VZ-R-14 Rack-and-pinion expander for thoracic cavity with mirror flow from 0 to 165 mm.

Surgical pushing instruments
The instruments are designed to expand wounds, cavities, passages and to push back organs that are not undergoing surgical intervention to protect them from accidental trauma.The base of slatted wound expanders is two parallel slats spaced at a distance of 30-50 mm. One working part of the retractor is rigidly fixed at one end of the slats. The other part is movable and slides along the rail due to the end slots. Fixation of the mobile part of the wound spreader after the wound edges separation is due to the friction force with a slight "skewing" of the windowed slit.It is used for the separation of the wound edges formed by low-elastic soft tissues or ribs, for keeping the wound edges in a given fixed position for a long time without the help of a surgical assistant, for adjustable separation of the wound edges by a given amount..
