技术领域technical field
本实用新型属于医疗器械技术领域，特别是涉及一种介入导管。The utility model belongs to the technical field of medical instruments, in particular to an intervention catheter.
背景技术Background technique
目前针对心血管病的微创介入手术是在X射线等医学设备的引导下，借助于导管通过血管管腔到达体内较远的病变部位，然后实施诊断或治疗的一种医疗技术。但是由于人体内的血管、心脏等形状弯曲狭长多变，对于导管导丝的操控产生很大的不利影响，目前的导管导丝操作器是通过螺纹配合压紧卡爪，然后通过旋转，推进操作器使导丝转动和向前运动，但是当操作器到达导管口时需将操作器向后移动，然后再次卡紧操作，通常这时需要医生通过双手操作，非常麻烦，且容易导致导丝窜动等给患者带来不利的影响。At present, minimally invasive interventional surgery for cardiovascular diseases is a medical technique that uses catheters to reach distant lesion sites in the body through the lumen of blood vessels under the guidance of medical equipment such as X-rays, and then implements diagnosis or treatment. However, due to the curved, narrow, long and changeable shapes of blood vessels and hearts in the human body, it has a great adverse effect on the manipulation of catheter guide wires. The current catheter guide wire manipulator is to press the claws through threaded cooperation, and then rotate and push the operation The manipulator makes the guide wire rotate and move forward, but when the manipulator reaches the catheter port, the manipulator needs to be moved backward, and then clamped again for operation. Usually, the doctor needs to operate with both hands, which is very troublesome and easily causes the guide wire to escape Movement, etc. have adverse effects on patients.
