Esophageal cancer local chemotherapy device

Abstract

The present invention discloses an esophageal cancer local chemotherapy device. The esophageal cancer local chemotherapy device comprises a skeleton catheter and a medicine inlet pipe, the medicine inlet pipe is installed in the center of the interior of the skeleton catheter, an air bag assembly comprises air bags, a circular baffle, a compression spring, a cavity and air bag inner cylinders, the multiple air bag inner cylinders are located on the upper side and the lower side of the outer wall of the skeleton catheter respectively, the circular baffle is fixedly connected with the skeleton catheter, and the two sides of the compression spring are fixedly connected with the circular baffles and the inner walls of the air bag inner cylinders respectively. According to the esophageal cancer local chemotherapy device, through cooperation of a groove block, a base, a first arc-shaped groove, a second arc-shaped groove, the air bags and the skeleton catheter, the groove block can drive a convex block of the base to move from the first arc-shaped groove to the interior of the second arc-shaped groove, the base can drive the air bags to move outwards by a certain distance, the size between the two air bags is increased, and the problem that the relative position of the positioning air bags cannot be adjusted according to the size of a focus in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of chemotherapy, in particular to a local chemotherapy device for esophageal cancer. Background technique [0002] Esophageal cancer is a common malignant tumor in humans, accounting for more than 90% of esophageal tumors. It ranks second only to gastric cancer in the retrospective survey of all malignant tumor deaths. It is estimated that about 200,000 people die of esophageal cancer every year in the world. , is one of the most common malignant tumors that are extremely harmful to people's lives and health. Chemotherapy is the abbreviation of chemical drug therapy. It is a systemic treatment method, together with surgery and radiotherapy, and is called the three major treatment methods for cancer, although the existing technology can achieve local chemotherapy for esophageal cancer. [0003] However, in the prior art, in the process of local chemotherapy for esophageal cancer, there is a problem that the ...
