초록 ▼

A cryogenic scalpel comprises a hollow housing, a pressure source, a working portion connected to the hollow housing and having a heat-exchanger communicating with the pressure source through a piping, and a blade. The scalpel comprises also a source of electromechanical oscillations located in a hollow housing and establishing reciprocating motion of the working portion, and a unit for imparting electromechanical oscillations to the working portion, interconnected to the source of electromechanical oscillations.

대표청구항 ▼

A cryogenic scalpel for conducting surgical operations on parenchymatous biological tissues, comprising: a hollow housing having an interior space; a working portion connected to said hollow housing and having a body extending in a lengthwise direction; heat-exchanger means for establishing a zone for cooling biological tissues during surgery by supplying cooling fluid to said interior space; a blade having two ends and a cutting lip, said ends of said blade being secured to said heat-exchanger means; a coolant free to circulate through said heat-exchanger means; a piping accommodated in said interior space of said hollow housing and communicating with said heat-exchanger means; a source of electromechanical oscillations accommodated in said hollow housing to establish reciprocating motion to said working portion with a frequency of electromechanical oscillation with the result that heating of said blade is precluded and parenchymatous biological tissues are separated by simultaneously cooling in said cooling zone created by said heat-exchanger means; and means for imparting electromechanical oscillations to said working portion so as to transmit reciprocating motion to said blade; said means for imparting being connected between said source of electromagnetic oscillations and said blade.
