Description
Technical Field
The invention belongs to the technical field of auxiliary medical appliances, and particularly relates to a multifunctional multi-cavity balloon catheter and a use method thereof.
Background
With the development of medical technology, intravascular interventional surgery is widely used for treating various clinical diseases by virtue of the characteristics of small incision, low trauma, quick recovery and the like. In the operation, the rapid, accurate and stable arrival of the intervention consumables such as guide wires, catheters, stents, spring rings and the like to the blood vessels to be reached becomes an important factor for shortening the operation time, reducing the operation complications and improving the operation success rate.
Most of the catheters used at present adopt catheters with a plurality of specifications and balloons which are matched and combined with skilled intravascular operation to meet the requirements, but in the clinical operation process, the condition of complicated vascular conditions is often met. For example, when selecting a blood vessel at the opening of a bifurcation of the blood vessel, several situations may lead to difficulty in selecting the target blood vessel, where the guidewire cannot enter the target blood vessel:
firstly, the target blood vessel is too thin, and the other branch blood vessel is obviously thicker; secondly, the angle between the target blood vessel and the approach blood vessel is too large; and thirdly, the target blood vessel is too twisted. For a blood vessel to be embolized, the following may result in embolization failure: the pressure in the direction of the approach blood vessel is obviously higher than that of the far end, the blood flow speed is high, and the spring ring and the like can not be fixed in situ or accumulated in multiple ways before the release is finished.
The above conditions can lead to obvious increase of the operation difficulty and even operation accidents. Therefore, the novel multifunctional multi-cavity balloon catheter designed by the invention can more effectively treat and solve the complex vascular disease condition, better provide a powerful tool for clinical vascular intervention operation, and provide new assistance for development of a new operation mode.
