Abstract

The invention discloses a balloon for closing a blood vessel, and relates to the technical field of medical instruments. The balloon for closing the blood vessel comprises a needle tube and a balloon body, wherein an annular cutting edge is arranged at one end of the needle tube, at least one opening hole is formed in the side surface of the needle tube, the opening hole is close to the annular cutting edge, the needle tube can be inserted into the outer side of the blood vessel through the annular cutting edge and enables the opening hole to face the blood vessel, the balloon body can enter the needle tube and penetrate out of the opening hole to abut against the outer side wall of the blood vessel, and the balloon body can expand to extrude the blood vessel till the blood vessel is closed. According to the balloon for closing the blood vessel, the balloon does not need to be inserted into the blood vessel, and the blood vessel can be extruded from the outside to be closed only through balloon expansion, so that damage to the blood vessel is avoided, the risk of blood vessel damage is avoided, and medical accidents such as massive hemorrhage and the like during liver resection can be prevented; and the annular cutting edge is arranged, so that the needle tube can be conveniently inserted into tissue, and the operation time is shortened.

Description

Technical field [0001] Technical Field The present invention relates to medical devices, particularly to a closed vessel balloon. Background technique [0002] In the embodiment hepatobiliary surgery liver resection surgery, liver need precise positioning segment boundaries, it is desirable approach is to target the liver sections stained dyeing or reverse, but the current technology system hepatic arteries complex superselective catheterization dyeing operation, costly, time consuming, difficult to implement basic. There are many blood vessels in the liver, such as the portal vein, if the surgery cut off an important portal vein may cause bleeding and even medical malpractice death of the patient, so doctors need to first portal vein is closed, preventing removal of the liver vascular hemorrhage, then be peripherally intravenous injection of dye, the target segment reverse liver stained to provide an indication of removal of tissue boundaries and contours. At present the art of ...
