Description
The invention relates to a medical instrument for treating cardiovascular diseases by using a minimally invasive intervention method, in particular to a double-balloon stent device for coronary artery dilatation angioplasty without need of exchange type subcutaneous puncture.
For various reasons, the cardiovascular disease is in a high level, such as coronary heart disease like myocardial infarction, or because blood has high blood fat and high blood viscosity, when blood flows in a blood vessel, blood with high blood fat and high viscosity is accumulated on the inner wall of the blood vessel, so that the wall of the blood vessel is thickened, a pipeline through which blood can flow in the blood vessel is reduced or even blocked, and the cardiovascular disease with more serious consequences is caused.
There are various surgical methods for angioplasty, and the treatment of cardiovascular diseases by minimally invasive intervention represents the highest surgical level worldwide and is a major trend not developed in the medical world. The subcutaneous puncture coronary artery dilatation (PTCA) represents the high technical level of minimally invasive interventional therapy, and is characterized in that a balloon dilatation catheter is introduced into a blood vessel through subcutaneous puncture, a balloon part in the balloon dilatation catheter is inserted into a stenotic lesion in the cardiovascular of a human body to be dilated or other treatments are carried out to relieve or completely treat various cardiovascular diseases, and after the operation is finished, the balloon is contracted along with the catheter and is led out of the body along with the catheter.
There are two types of PTCA balloon stent devices that currently represent the highest levels internationally: one is the coaxial (OTW) and the Rapid Exchange (REX), the two PTCA catheters are fundamentally different in that in the coaxial (OTW) balloon stent device, the length requirement of the guide wire is very long, and therefore the exchange of the guide wire is rather time-consuming; thus, a Rapid Exchange (REX) has been developed to facilitate rapid and convenient replacement of the guide wire. In clinical use, the coaxial (OTW) requires two doctors to perform the operation, while the Rapid Exchange (REX) requires only one doctor to complete the whole operation.
However, whether it is an in-line (OTW) balloon stent device or a Rapid Exchange (REX) balloon stent device, it is necessary to use two forms of products, one is called a "PTCA balloon dilatation catheter" and the other is a "PTCA stent catheter", in use. In the whole PTCA operation process, the PTCA balloon catheter adopting the coaxial type (OTW) (also called rear-mounted type) or the rapid exchange type (REX) (also called front-mounted type) can not avoid the secondary intervention operation method, namely the exchange type, of firstly inserting the balloon part of the PTCA balloon dilatation catheter into a stenotic lesion in a cardiovascular of a human body to dilate, taking out the catheter after the blood vessel is recovered to be normal, then replacing a PTCA stent catheter to enter a position where the cardiovascular stenosis is subjected to pre-dilation, and taking out the catheter after releasing the stent.
From the above, the existing "PTCA balloon dilatation catheter" and "PTCA stent catheter" are developed from OTW (coaxial or rear-mounted) to REX (rapid exchange or front-mounted) in consideration of the operation, so that the operation procedure of two doctors can be changed to one doctor to complete the operation procedure, however, both OTW and REX fail to solve the problem of the two-time catheter intervention into the blood vessel of the patient, and the two-time catheter intervention not only increases the pain of the patient, but also increases the operation cost.
