Abstract

The invention provides a puncture catheter for chemotherapy. The puncture catheter comprises a catheter body. The front end of the catheter body is surrounded by multiple elastic rods, the portions, surrounded by the elastic rods, of the catheter body are provided with multiple liquid inlets, the initial states of the elastic rods are arcs protruding outwards, the rear ends of the elastic rods are fixed to the outer side wall of the catheter body, the front ends of the elastic rods are connected to a front supporting frame, a rear supporting frame with a through hole is fixed to the inner side wall of the catheter body, and a soluble supporting device for straightening the elastic rods is arranged between the front supporting frame and the rear supporting frame. The soluble supporting device can support the elastic rods in a straight state, after the puncture catheter is inserted into the human body, the soluble supporting device is dissolved, after no supporting effect exists, the elastic rods restore to the initial states to protrude outwards, human tissue around the front end of the catheter body is expanded, and the smoothness of the puncture catheter is guaranteed.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a puncture catheter for chemotherapy. Background technique [0002] Cancerous peritoneal effusion is the most common concomitant disease of advanced malignant tumors. As an effective treatment for cancerous ascites, hyperthermic perfusion chemotherapy has been widely used in clinic. The principle is to use physical energy to heat chemotherapy drugs with good thermal effects, infuse them into the tumor site, make the temperature of tumor tissue rise to the effective therapeutic temperature, and maintain it for a certain period of time, and use the difference in temperature tolerance between normal tissue and tumor cells to achieve both The purpose of treatment is to induce apoptosis of tumor cells without damaging normal tissues. [0003] Before the implementation of hyperthermic perfusion chemotherapy, catheters need to be inserted into the human thoracic and abdominal cavity t...
