Intervention auxiliary device

Technical Field

The invention relates to the technical field of medical auxiliary equipment, and particularly provides an intervention auxiliary device.

Background

Extracorporeal Membrane Oxygenation (ECMO) is a mechanical aid for the treatment of patients with acute myocardial infarction with cardiogenic shock and high-risk complex coronary diseases, and generally adopts a VA-ECMO mode (arterial-venous circulation supports ECMO mode), and the operation inevitably occupies the femoral artery.

Percutaneous Coronary Intervention (PCI) generally employs the radial artery or femoral artery as an access path, and an inserted sheath as a passage to deliver devices such as a catheter, a guide wire, a balloon, and a stent into the body. In many clinical situations, patients with acute myocardial infarction combined cardiogenic shock and high-risk complex coronary lesion need to perform PCI operation under the assistance of ECMO, and the femoral artery is occupied, so that the peripheral artery of the arm needs to be sheathed to establish a PCI access. In addition, the operation of sheathing the peripheral artery of the arm increases the puncture rate of the PCI operation under ECMO, so that the probability of peripheral vascular complications is increased, and the economy and puncture burden of a patient are increased.
