Abstract

The invention discloses a nasopharynx cancer plasma treatment generating device. An insulating tube is sleeved with a stainless steel sleeve, a first annular electrode and a second annular electrode are coaxially arranged in the insulating tube and spaced, the interiors of the first annular electrode and the second annular electrode are sequentially communicated to jointly form a plasma generatingchannel, an air inlet is formed in one end of the plasma generating channel, and a plasma jet orifice is formed in the other end of the plasma generating channel. The nasopharynx cancer plasma treatment generating device in optimization design can be installed on a nasal endoscope, plasma is generated in the plasma generating channel, the nasal endoscope stretches into the nasal cavity, the plasma is generated under a discharge effect, and therefore malignant tumors on the top and the side wall of the pharyngonasal cavity can be killed under a clear view. The invention further provides the nasal endoscope.

Description

technical field [0001] The invention relates to the technical field of nasopharyngeal therapy, in particular to a device for generating plasma therapy for nasopharyngeal carcinoma and a nasal endoscope. Background technique [0002] Nasopharyngeal carcinoma (Nasopharyngeal Carcinoma) is one of the malignant tumors with high incidence in my country. According to epidemiological survey data, Guangdong, Guangxi, Hunan, Fujian, and Jiangxi in my country are the high incidence areas of nasopharyngeal carcinoma in the world, and the incidence rate of men is about 2-2% of that of women. 3 times, 40 to 50 years old is the high incidence age group. At present, the commonly used methods for clinical treatment of tumors include surgical therapy, radiotherapy, and chemotherapy. Surgical therapy is only a local treatment, which is often difficult to cure completely, and is prone to recurrence after surgery; Side effects such as nausea, vomiting, hair loss, and fatigue; radiation therapy,...
