Abstract

The invention provides a drainage catheter, which comprises a guide tube, a balloon group, connecting tubes and connecting joints the two ends of the guide tube are opened, the balloon group is arranged on the outer wall of one end of the guide tube and comprises a plurality of balloons, the balloons are distributed in the circumferential direction of the guide tube at intervals, the number of theconnecting tubes is the same as that of the balloons, one end of each connecting tube is connected with the corresponding balloon and communicated with the inner cavity of the balloon, the number ofthe connecting joints is the same as that of the balloons, and the connecting joints are communicated with the other ends of the connecting tubes respectively and can be used for being connected withinjectors. During use, the balloon is inflated by injecting gas or liquid into the balloon through the connecting joint and the connecting tube by using the injector, and the size of each balloon is adjusted as required, so that the peritoneal wall is separated from organs, a surgical operation space is provided, and an endoscope or a manipulator can extend into the abdominal cavity through the guide tube to perform surgical operation and examination.

Description

technical field [0001] The invention relates to the technical field of abdominal cavity drainage, in particular to a drainage catheter. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, and it is an inevitable trend in the development of future surgical methods. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open operations in the past have now been replaced by endovascular surgery. Greatly increased surgical options. [0003] Laparoscopic surgery usually requires general anesthesia on the patient before the operation, and the establishment of artificial pneumoperitoneum to separate the peritoneal wall from the organs, expand the abdominal cavity to facilitate the operation, and avoid damage to the organs when the trocar is ...
