Abstract

The invention relates to the technical field of medical instruments, and discloses an esophagus cancer local chemotherapy tube. The tube comprises an outer cannula, a plurality of through grooves, a plurality of spraying heads, a connecting tube, an inner cannula and a chemotherapy tube joint; the through grooves are circumferentially and symmetrically formed in the outer cannula uniformly in thelength direction of the outer cannula, the cross section of each through hole is two symmetrical structures in a shape like the Chinese character of 'ao', and the spraying heads are correspondingly arranged in the through holes and move up and down along the through grooves; spraying holes are formed in the spraying heads, the spraying heads are respectively connected to the outer end of the connecting tube, the inner end of the connecting tube is communicated with the lower end of the inner cannula through a first tube joint, and the upper end of the inner cannula penetrates out of the upperend of the outer cannula and is communicated with chemotherapy tube joint. The esophagus cancer local chemotherapy tube relieves the chemotherapy pain of patients and improves the chemotherapy effectof the esophagus cancer.

Description

Technical field [0001] The invention relates to the technical field of medical appliances, in particular to a tube for local chemotherapy of esophageal cancer. Background technique [0002] Esophageal cancer is a common disease and frequently-occurring disease in my country. Male esophageal cancer ranks second in the death of malignant tumors, second only to gastric cancer, while female esophageal cancer ranks third, next to gastric cancer and cervical cancer. It can be seen that esophageal cancer is one of the tumors that seriously threaten people's lives and health. Therefore, the treatment of esophageal cancer has received widespread attention. [0003] At present, the treatment of esophageal cancer is mainly surgical resection and radiotherapy, while systemic chemotherapy is generally used for postoperative treatment of patients with esophageal cancer. However, the response to systemic chemotherapy is severe and the patient is very painful. Local chemotherapy is an ideal met...
