Kind Code:
A
Abstract:
To provide a cryoprobe having a working tip formed of two coaxial flexible internal and external tubular lines.SOLUTION: A cardiac surgery cryoprobe is provided in which the cross-section diameter of an internal line is substantially smaller than the cross-section diameter of an external line, and the length thereof is slightly smaller than the length of the external line. The external line ends with a top closing a working tip of the cryoprobe, while the end of the internal line is open, and there are openings evenly distributed across the circumference on at least half of a section of the internal line. On a section from a handle to the end located under the top, a resistance wire is spirally wound on the internal line, wherein the distance between the wall of the external line and the wall of the internal line is larger than the diameter of the resistance wire. On the external line, there is a temperature sensor connected to the handle by a power line. An external line and an internal line corresponding to the external line and the internal line come out from the working tip outside the handle.SELECTED DRAWING: None
