Emergency hemostasis method and emergency hemostasis device for vascular surgery

Abstract

The invention discloses an emergency hemostasis method and an emergency hemostasis device for vascular surgery. The method is mainly realized by the following methods: determining a blood vessel that needs hemostasis, puncturing a blood vessel wall of the blood vessel from a bleeding site, sending an inflatable balloon matching a diameter of the blood vessel into the blood vessel, and blocking a blood flow channel inside the blood vessel through the inflatable balloon, so as to achieve a purpose of blood vessel hemostasis; withdrawing gas from the inflatable balloon and withdrawing the inflatable balloon from the blood vessel after surgery. The invention further discloses an emergency hemostasis device suitable for the emergency hemostasis method. The emergency hemostasis device comprises a pressing structure, a positioning structure, an air compression structure, an outer sleeve, a balloon gas injection pipe and an inflation balloon. The method and device can complete two actions of needle tip recovery and balloon inflation at the same time; are simple to operate, convenient and quick to use, have good hemostasis effect, and have little damage to blood vessels, are particularly suitable for patients whose blood vessels are fragile and cannot be stopped by clamping and compression methods such as vascular clamps, and are also particularly suitable for hemostasis in emergencies that occur during surgery.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary devices, in particular to an emergency hemostasis method and an emergency hemostasis device for vascular surgery. Background technique [0002] When the surgeon performs the operation, he will choose different hemostasis methods according to the bleeding blood vessel and the bleeding site. Generally, arteries are the main source of vascular bleeding. Because of high blood pressure, the bleeding is fast and profuse. Sometimes veins also bleed, but the pressure is low, and many small venous bleeding can be stopped by compression. For subcutaneous microvascular bleeding, it can usually be stopped by electrocautery or bipolar coagulation. For small arteries and venous bleeding with large diameters, the blood vessels are generally clamped with hemostats first, and then surgical thread ligation is used to stop bleeding or blood vessels are sutured or hemangioma clips are clamped. However, fo...
