Technical Field

The invention relates to a medical instrument, in particular to a manufacturing technology of an OCT catheter, and specifically relates to a catheter moving device for an OCT catheter dispensing positioning and UV glue curing tool.

Background

At present, an intravascular tomographic imaging system is designed to be used for imaging blood vessels with the diameter larger than 1.5mm in cooperation with an imaging catheter, so that the diameter and the area of a lumen are accurately measured, the structures of the blood vessel wall and the intravascular implant are imaged, and then the plaque property is distinguished and the intravascular implant (a stent, a filter, a spring ring and the like) is evaluated.

The intravascular tomographic imaging system is a system based on the combination of an intravascular Optical Coherence Tomography (OCT) technology and an imaging catheter, and the OCT technology is a new intracoronary imaging technology that appears after intravascular ultrasound (IVUS), and compared with IVUS, the extremely high resolution of OCT makes it increasingly interesting for evaluating vulnerable plaque, guiding stent implantation, and especially for Acute Coronary Syndrome (ACS) diagnosis and treatment.

In 2011, the american society of cardiology/american heart association (ACCF/AHA) Coronary Intervention guideline recommended levels for IVUS in Percutaneous Coronary Intervention (PCI) were IIa, while those for OCT were not established due to insufficient evidence of evidence-based medicine. In 2012, the CLI-OPCI study showed that OCT-directed PCI treatment could significantly improve patient prognosis compared to the plain contrast-directed PCI treatment. Subsequently, OCT was classified as a grade IIb recommendation (grade B evidence level) for assessing lesion characteristics and optimizing the stent implantation procedure in the 2013 european cardiology society for stable coronary heart disease management guidelines, with a global evidence level equivalent to IVUS. In 2014, the recommendation level of OCT for optimizing PCI was elevated to a level IIa recommendation equivalent to IVUS in the european society of cardiology/european association of cardiothoracic surgery (ESC/EACTS) myocardial revascularization guideline. The ILUMIEN I study published in 2015 showed that OCT examinations performed before and/or after PCI could affect the intervention strategy of the surgeon. The ILUMIEN II study results show that OCT is not inferior to IVUS in guiding stent expansion. With the continuous update of the OCT technology and the publication of more prospective research data, the position of OCT in the field of coronary heart disease interventional diagnosis and treatment is certainly to be further promoted.

The OCT catheter is composed of multiple sections, dispensing and curing are needed in the preparation process, and meanwhile, the probe position at the end part of the catheter is required to be accurate, so that in order to improve the production effect, a corresponding tool needs to be designed to improve dispensing precision and production effect, and the catheter moving device is the key for ensuring the accurate position of the probe of the catheter before dispensing, so that the catheter must be designed to move to a correct position before dispensing.
