Abstract

Изобретение относитс  к медицинской технике, а именно к хирургическому режущему инструменту дл  обработки костной ткани. Целью изобретени   вл етс  снижение травматичности. Пила имеет трехслойное полотно 1, пропитанное хладагентом 5 с режущими зубь ми 2 и центральным отверстием 3, вокруг которого установлен теплообменник в виде по меньшей мере одной спирали 8. Во врем  резани  кости хладагент 5, соприкаса сь со спиралью 8, конденсируетс , отдава  тепло спирали и окружающему воздуху. 3 ил.The invention relates to medical technology, in particular to a surgical cutting tool for treating bone tissue. The aim of the invention is to reduce the morbidity. The saw has a three-layer blade 1 impregnated with coolant 5 with cutting teeth 2 and a central hole 3 around which a heat exchanger in the form of at least one helix 8 is installed. During the cutting of bone, coolant 5 condenses into contact with heat of the helix and the surrounding air. 3 il.
