Description

Quick-contraction saccule holding catheter device

Technical Field

The utility model relates to the technical field of coronary stent interventional operation devices, in particular to a rapid-contraction balloon hugging catheter device.

Background

When a doctor performs a coronary stent implantation operation or other intravascular operations, a balloon catheter device is used, a sheath tube is generally stretched into a blood vessel of a patient along a guide wire playing a role of a track during use, then the balloon is stretched into the blood vessel of the patient along the sheath tube, after the balloon stretches out of the sheath tube to a proper position, namely, a pressure pump is connected, a ventilation pipeline and the pressure pump are communicated with the balloon to be inflated or contrast medium, so that the balloon is inflated, the functions of expanding the blood vessel and fixing are achieved, after the balloon is used, the pressure pump is required to be given to carry out negative pressure air suction outwards, so that the balloon is retracted, and then the balloon is withdrawn from the blood vessel of the patient along the sheath tube. However, if the ventilation pipeline is damaged in the pushing process of the balloon, the most common cause is the discount, the pressure pump and the balloon cannot be connected smoothly, so that the balloon cannot be held back after an operation, medical accidents are caused, heart blood of a patient cannot circulate for a long time, artificial myocardial infarction is caused, and life danger is likely to be caused.

At present, the doctor usually cuts the balloon part of the other balloon, leaves a sharp steel wire, stretches the steel wire into the blood vessel of the patient along the sheath tube until the balloon is filled, and tries to puncture the filled balloon with the steel wire. However, due to urgent conditions, the operation time of doctors is not long, most doctors often cannot control the force because of being too urgent, so that the vascular wall of a patient is severely scratched while the balloon is tried to be punctured, and the physical injury to the patient is extremely serious; secondly, a doctor selects a mode of violently pressurizing and breaking the balloon to retract the balloon, the operation risk is extremely high, the large stent balloon is broken, serious interlayer or vascular rupture can be generated, and the current patent for solving the problem has larger defects (patent number: 201910229513.2): the existing sheath needs to dissolve mannitol protective film in blood vessel for a long time, so as to prolong myocardial ischemia time; the existing sheath head needle is extremely easy to damage the inner wall of a blood vessel; the existing sheath tube needs to pull the candela saccule, which is easy to cause vascular injury and support the stent, and brings more harm to patients.
