New Materials and New Technologies Give New Possibilities for PCI Surgery

1. What is the medical balloon inflation device?

The medical balloon inflation device is composed of a push handle, a push rod, a wrench, an injection tube, a sealing rubber plug, a pressure gauge, a pressure tube, and a conical locking fixed anode connector. The inflation device should be sterile.

The medical balloon inflation device is suitable for percutaneous transluminal coronary angioplasty (PTCA) or peripheral vasodilation surgery. During the operation, an angioplasty balloon inflation device is used to pressurize the balloon expansion catheter to expand the balloon to achieve the purpose of expanding the blood vessel or placing a stent in the blood vessel.

2. Application of the medical balloon inflation device in angioplasty

After the coronary artery probe is used to pass through the artery incision to be bypassed and respectively detect the distal and proximal stenosis sites and degrees, then the balloon catheter is inserted through the coronary artery incision to the stenosis site to be expanded for expansion.

During the operation of coronary artery balloon expansion, the surgeon can diagnose and observe the lesion site on the operating table. During expansion, use a medical balloon inflation device to inject lactated Ringer's solution into the balloon and gradually increase the pressure to 10 atmospheres for 60 seconds. Repeat this for 2 or 3 times, then remove the balloon fluid and remove the catheter. Use a coronary probe to re-measure the diameter of the stenosis. If the diameter is not large enough, or it is increased by less than 50%, the expansion should be repeated, and then cardioplegia should be perfused to flush out the debris that may exist in the lumen, and then the vascular bridge anastomosis should be performed. Be careful not to use large sacs to expand small blood vessels. The criterion for successful expansion is to make the narrow part reach the normal diameter, or increase it by more than 50%.

Stent implantation brings new breakthroughs

A common PCI treatment method is to send a balloon catheter through the femoral artery or radial artery to the coronary artery stenosis of the heart, inflate the balloon through a medical balloon inflation device to expand the lumen and improve blood flow, and complete the expansion. Then place a heart stent in the narrowed lumen to prevent re-stenosis. At present, PCI treatment technology is mature and highly safe with low mortality. Besides, complications such as contrast agent allergy, pericardial effusion, and pericardial tamponade are relatively rare. It is more and more widely used in the treatment of coronary heart disease.
