Abstract
The invention discloses a blood vessel dilation device and method. The problem that time and labor are wasted in the micro blood vessel anastomosis and suturing process in the prior art is solved. The blood vessel dilation device comprises a balloon dilator, an automatic liquid charging and discharging device and an absorbable blood stent, the balloon dilator is connected with an injector connector of the automatic liquid charging and discharging device, and the absorbable blood stent sleeves the outer part of the balloon dilator; and the balloon dilator comprises a balloon, an L-shaped metal catheter and a blunt straight needle, the tail end of the blunt straight needle is connected with the head end of the L-shaped metal catheter, a lateral vent hole is formed in the middle of the L-shaped metal catheter on the head end side, and a connector is arranged at the tail end of the L-shaped metal catheter on the tail end side. The technology is applied to clinical surgical medical treatment, a good auxiliary method is provided for pure blood vessel anastomosis, the blood vessel suture difficulty can be reduced, the blood vessel repair speed can be increased, and the probability of postoperative reembolism can be reduced by placing the blood vessel stent.
Description
Technical field [0001] The present invention relates to medical equipment and its clinical applications, and in particular, to a vascular expansion device and a method thereof. Background technique [0002] For the anastomosis of the vasodilator, such as the retraction, vein repair, due to the thickness of the lumen, the front and rear wall of the lumen can be clearly separated, the naked eye or the auxiliary magnifier can be sewed. However, for the repair of medium and small blood vessels, especially the veins of the arteries, the front and rear walls are easy to fit, causing the stitching difficulties, and difficult to control the stitching of the non-full sewing. There is happening. In order to change this situation, currently common methods are magnetized, anastomotic, needle ring method, and artificial blood huger kiss. Magnetic pipe method can quickly suck together, reduce the sewing process, but there is no magnetic force, large volume, and need to be in vivo in vivo. The ...
