Problems solved by technology

[0004] The safe time limit for such major surgery is about 30 minutes. If the aortic occlusion time exceeds 45 minutes, the possibility of paraplegia or renal failure will increase greatly.
Therefore, in this type of operation, doctors have to race against time to perform surgery to reduce the time of aortic occlusion, which will increase the psychological pressure of doctors, and problems such as insufficient operation and misoperation will occur. In some special cases, aortic occlusion may occur. If the interruption time exceeds 45 minutes, the patient's risk rises sharply

Embodiment 1

[0037] Embodiment 1: A kind of medical catheter and using method

[0038] A 24-year-old female patient was admitted to the hospital due to coughing and hemoptysis. She was diagnosed with left lung cancer by CT. However, the tumor grew to the adjacent aorta and wrapped around the local thoracic aorta. Since the aorta is invaded, conventional surgery may damage the aorta leading to fatal hemorrhage without complete resection. With the application of the invention, the tumor tissue and the invaded aorta can be safely and completely removed, and the affected thoracic aorta can be replaced with an artificial blood vessel, which can be completed without extracorporeal circulation assistance.

[0039] A medical catheter includes: 1-soft thick sleeve I; 2-fixing device; 3-connection port; 4-wire; 5-blood flow detector; Soft thick cannula II; 9-blood flow detection head; 10-dilation sheath; 11-blood flow regulation head.

[0040] The patient underwent thoracotomy through a posterolat...

Abstract

The invention belongs to the field of medical devices and equipment, and particularly relates to a medical catheter structure, a purpose and a use method. The medical catheter structure disclosed by the invention mainly comprises a soft thick casing pipe I, a soft thick casing pipe II, connecting ends II, a pipeline blood flow control device and a blood flow detection meter. When a catheter bridging manner is used, tumor tissue, invaded aorta or other artery vessels can be safely and completely excised, the problem that a malignant diseased region is difficult to be subjected to a surgery is solved, and the medical catheter structure can be further widely applied to the field of medical care.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a medical catheter structure, use method and use thereof. Background technique [0002] Major Vascular Surgery Field [0003] There are some clinical diseases such as congenital aortic stenosis, congenital aortic atresia, aortic stenosis caused by vasculitis, adjacent organ tumors invading the aorta, etc. The operation involves the thoracic aorta or abdominal aorta, and temporary surgery is required during the operation. Blocking the aorta will lead to a sudden interruption of blood flow in the aorta, and the blood ejected from the heart will gather at the proximal end of the blockage, showing a sharp increase in blood pressure at the proximal end of the blockage. Significantly lower, severe ischemia and hypoxia state, may involve spinal cord, kidney and other important organs. [0004] The safe time limit for such major surgery is about 30 minutes. If the aortic occlusion time e...
