Description

PTCA guide wire fixing device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to PTCA seal wire, especially a PTCA seal wire fixing device.

Background

Coronary intervention is a non-surgical treatment of minimally invasive coronary heart disease. Coronary intervention (TFI) via the femoral artery approach is gradually replaced by radial artery approach intervention (TRI) due to its postoperative complications such as hematoma at the puncture site, vasovagal reflex, venous thrombosis of the lower extremities, arteriovenous fistula, pseudoaneurysm, etc. TRI is a novel interventional therapy method, has small operative trauma and few complications, does not need position limitation after operation, and is more easily accepted by doctors and patients.

During coronary intervention, the PTCA guide wire is a life line, and the balloon and the stent are moved in and out of the guide catheter and the coronary artery along the PTCA guide wire. Keeping the PTCA guidewire stable during surgery from being fed too far or carried out is an important prerequisite for surgical safety. In the operation, when the operator pushes the balloon or the stent along the guide wire, an assistant is needed to help to fix the guide wire, so that the guide wire is prevented from being moved when the balloon or the stent is pushed and withdrawn. If the guide wire is not fixed, the guide wire can be brought into the blood vessel when the instruments are pushed into the catheter, the blood vessel at the far end can be punctured in serious cases, the guide wire can be taken out when the instruments are withdrawn, and the guide wire cannot be sent into the true cavity at the far end of the blood vessel again in some cases, so that disastrous results are caused. When a plurality of guide wires are in the coronary artery, one guide wire is easy to move along with the other guide wire when being operated, so that the operation risk is caused, and if one device can fix the guide wires, the operation safety can be improved.

At present, most coronary intervention operations are radial arteries, the position operated by an operator is often located on the right side of the body of a patient, a flat platform is lacked, a guide wire catheter easily slides down to the position under the platform when careless, if a guide wire fixing device can fix a guide wire, an operation platform can be provided for the operator to prevent instruments from sliding down, and the convenience of the operation can be improved.

SUMMERY OF THE UTILITY MODEL
