摘要: A cryosurgical system using a low-pressure liquid nitrogen supply, which requires only 0.5 to 15 bar of pressure to provide adequate cooling power for treatment of typical breast lesions. The pressure may be provided by supplying lightly pressurized air into the dewar, by heating a small portion of the nitrogen in the dewar, or with a small low pressure pump.
