Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a flow bypass device for the proximal end of a femoral artery combined surgery. Background Art

[0002] Peripheral atherosclerotic disease is a disease that can seriously affect the patient's quality of life and can lead to limb ischemia, movement disorders, and even gangrene. With the development of interventional technology and endovascular devices, endovascular treatment has become the main treatment for peripheral atherosclerotic disease. However, if the lesions accumulate in the common femoral artery, especially if the common femoral artery is severely calcified, stenotic, or occluded, simple endovascular treatment is often ineffective. Therefore, vascular surgeons generally choose a combined surgery to treat the lower limb arteries, that is, open surgery and interventional surgery combined with femoral artery incision and endarterectomy.

[0003] After the femoral artery opening surgery is completed and during the interventional surgery, the common femoral artery, deep femoral artery and superficial femoral artery still need to be blocked, which will cause the lower limbs to be in a state of continuous ischemia and increase the risk of limb necrosis, ischemia-reperfusion injury, etc. Utility Model Content
