[Device for the experimental local application of cold to organs and vessels of the abdominal cavity].

A study of the action produced by local freezing on the esophageal and gastric mucosa under conditions of acute hyperemia, on the veins and arteries of various diameter - for preventive stasis of the blood flow along them and on the nerve: carrying sheaths of major arteries made it possible to construct a cryosurgical instrument of a simple design and easy to handle. The working end of this instrument that acts on the organ undergoing operation is cooled down to -185 degrees. The instrument ensures a sufficiently effective utilization of the coolant and its low consumption during surgery.
