Description

TECHNICAL FIELD

[0001] The utility model relates to cardiovascular surgery technical field especially relates to a cardiovascular guide wire intervention guide. BACKGROUND

[0002] At present, when carrying out cardiovascular intervention treatment to patients, the guide wire intervention guide is mostly replaced by disposable syringe, that is, connecting the puncture needle to the syringe, inserting the puncture needle into the blood vessel, and then pulling the syringe off the puncture needle, and then inserting the guide wire into the puncture needle and into the blood vessel. In this way, a large amount of blood will flow out of the puncture needle when inserting the guide wire, which pollutes the work surface. At the same time, the exposed part of the puncture needle is short, so it is not easy to control the direction, and thus the needle tip of the puncture needle is easily displaced to injure the blood vessel.

[0003] In the prior art, patent number (CN200920091914.8) discloses a cardiovascular guide wire intervention guide for minimally invasive intervention surgery, which comprises a needle cylinder and a sealing ring. The needle cylinder has a needle seat at the front end, and the inner hole of the needle seat penetrates through the entire needle cylinder. The needle cylinder has a sealing ring at the inner hole of the rear end. The purpose is to ensure that blood does not leak from the rear end of the guide during operation when the guide wire is inserted into the needle cylinder. The guide has the advantages of simple structure, convenient use, and low cost. When using, the guide wire is inserted into the front end of the guide from the sealing ring hole at the rear end of the cardiovascular guide wire intervention guide. Then the puncture needle is mounted on the needle seat at the front end of the cardiovascular guide wire intervention guide and inserted into the blood vessel. Then the guide wire is pulled backward. If blood enters the needle cylinder, it means that the needle has been inserted into the blood vessel. At this time, the guide wire can be pushed forward into the blood vessel to complete the task of delivering the guide wire.

[0004] In the prior art, a sealing ring is added, which effectively prevents a large amount of blood from flowing out. This effectively solves the problem that a large amount of blood will flow out of the puncture needle when inserting the guide wire, which pollutes the work surface. At the same time, the exposed part of the puncture needle is short, so it is not easy to control the direction, and thus the needle tip of the puncture needle is easily displaced to injure the blood vessel. However, the needle cylinder is still hollow when in use, and the guide wire is still guided to puncture from the hollow part of the needle cylinder. The blood pressure of the human body varies in an instant when puncturing, which will cause the blood of people with high blood pressure to still flow out when puncturing, thereby affecting the vision of medical staff, and thus affecting the practicability of the whole.
