Cardiovascular intervention device

Abstract

The invention discloses a cardiovascular intervention device, which comprises a puncture device and a fixed device, wherein the puncture device comprises a needle tube; the needle tube is formed by threaded connection of a front end with a through hole, a plurality of sleeve tubes and a tail end with a rear wing; a membrane breaking tube is arranged on the top part of the front end; a needle head is arranged on one end, stretching out of the needle tube, of the membrane breaking tube; the other end of the membrane breaking tube extends into the needle tube; a push rod is arranged in the needle tube and is formed by threaded connection of a rubber plug, a plurality of sleeve tubes and a tail end with a push rod; a liquid storage cavity is arranged on one side of the front end of the push rod; a liquid inlet is formed in one side of the rubber plug; a through hole adaptive to the membrane breaking tube is formed in the rubber plug; a gauze sleeve is arranged on the through hole; a wire guide rod is arranged in the push rod; one end of the wire guide rod is communicated with the through hole; the other end tip of the wire guide rod extends out of the tail end with the push rod. According to the cardiovascular intervention device, doctors can operate more conveniently and accurately, blood is collected in a collection bag, the operation surface of the doctors is not polluted, the guidance of a guidewire is completed, meanwhile, the guidewire is disinfected, and the lengths of the needle tube and the push rod can be adjusted according to the needs.

Description

technical field

[0001] The invention relates to the field of medical devices, in particular to a cardiovascular interventional device. Background technique

[0002] At present, clinically, when performing cardiovascular interventional treatment for patients, the puncture needle is usually used to directly puncture the blood vessel or a common syringe is used to puncture the blood vessel, and then the syringe is removed from the puncture needle, and then the guide wire is sent into the blood vessel through the puncture needle. , this operation is easy to cause blood overflow, pollute the doctor's operating surface, easily cause cross infection, and bring great inconvenience to the doctor's surgical work. In addition, the doctor needs to carefully control the position of the puncture device. It is easy to puncture the blood vessel when the device is moved, resulting in operation failure, which adds great work difficulty to the doctor. At the same time, the length of the punctu...
