Abstract

A tubular inserter with freezing probe and able to be curved in cavity for the freeze therapy in seophagus cavity and bronchus cavity has a regulating valve, a connector connected to said regulating valve and with tube inlet, air exhaust outlet and electric plug, an inserted flexible tube containing a freezing tube and the electric line, and a freezing probe at the front end of said flexible tube and with a temp sensor on its inner surface.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bendable intracavity inserter provided with a cryoprobe. Background technique [0002] The incidence rate of esophageal cancer and lung cancer in our country is relatively high. For this kind of disease, surgical treatment is mostly adopted clinically, which causes relatively great pain to patients. With the continuous development of science and technology, the use of freezing to treat tumors has become a very effective new technology. It has the advantages of less trauma, less pain, less bleeding, high safety and prevention of tumor spread. It is widely used clinically. application. Chinese patent 02104246.2 discloses a flexible cold knife probe for cryotherapy of human cavity tumors. This invention uses liquid nitrogen as a refrigerant. The main body of the probe is made of flexible materials except for the knife head. The main body is divided into inner and out...
