Description
Technical Field
The invention relates to the technical field of interventional drug delivery, in particular to an environment-friendly interventional drug delivery device for treating liver cancer.
Background
Liver cancer, a malignant tumor of the liver, can be divided into primary and secondary types. The primary liver malignant tumor originates from the epithelium or mesenchymal tissue of the liver, the former is called primary liver cancer, which is a highly-developed malignant tumor with great harm in China; the latter is called sarcoma, and is less common than primary liver cancer. Secondary or metastatic liver cancer refers to the invasion of malignant tumors of multiple organ origins in the whole body to the liver. In liver cancer, vascular intervention therapy is mainly selected from selective hepatic artery perfusion therapy, selective hepatic artery embolism and selective hepatic artery chemoembolization. The main physiological basis is that the blood supply to normal hepatocytes is 20% -25% from the hepatic artery and 75% -85% from the portal vein. While 90-95% of blood supply of the primary liver cancer comes from hepatic artery, which provides anatomical basis for vascular interventional therapy of tumors of the liver cancer. The intervention treatment of liver cancer is called as intervention treatment of liver cancer, which is a minimally invasive treatment method that under the condition of exposing the focus without operation, a tiny channel with the diameter of several millimeters is made on the blood vessel and the skin or the original pipeline of the human body is used for treating the focus locally under the guidance of the imaging equipment (an angiography machine, a fluoroscopy machine, a CT machine, an MR machine and a B-ultrasound machine). The intervention treatment of liver cancer refers to regional local chemotherapy for injecting anticancer drugs or embolus into hepatic artery through femoral artery intubation, which is a preferred method for treating liver cancer by non-open surgery.
For example, patent CN201310211746.2 discloses a medical device for clinical minimally invasive interventional drug delivery, which comprises a guiding catheter and a catheter connector, wherein the guiding catheter is inserted into the distal end of the wing tube of the fixed wing and penetrates out from the proximal end of the connector, so that the drug injected into the proximal end of the guiding catheter can reach the distal end of the guiding catheter and further reach the internal position of the human body to be injected. The interventional device can be used for conveniently and simply implementing interventional treatment, so that the medicine directly reaches the focus, the local medicine concentration is high, the clinical curative effect is obviously improved, and the interventional device can be used for treating various diseases such as prostatitis and seminal emission (seminal vesiculitis) and can also be used for vasography, thereby diagnosing the diseases of the seminal tract.
