Description

Technical Field

[0001] The invention relates to a tooling fixture for manufacturing medical equipment, in particular to an OCT catheter manufacturing tooling, specifically to an OCT catheter welding tooling. Background Art

[0002] At present, the intravascular tomography system is designed in conjunction with an imaging catheter for imaging blood vessels with a diameter greater than 1.5 mm, achieving accurate measurement of lumen diameter and area, imaging of the vascular wall and intravascular implant structure, and further identifying plaque properties and for evaluation of intravascular implants (stents, filters, coils, etc.).

[0003] The intravascular tomography system is based on intravascular optical coherence tomography (OCT) technology combined with an imaging catheter. OCT technology is a new intracoronary imaging technology that emerged after intravascular ultrasound (IVUS). Compared with IVUS, OCT's extremely high resolution makes it increasingly popular in evaluating vulnerable plaques, guiding stent implantation, and especially in the diagnosis and treatment of acute coronary syndrome (ACS).

[0004] In 2011, the American College of Cardiology / American Heart Association (ACCF / AHA) Coronary Intervention Guidelines recommended the use of IVUS in percutaneous coronary intervention (PCI) as IIa, while the recommendation level for OCT has not yet been established due to insufficient evidence-based medicine. In 2012, the CLI-OPCI study showed that compared with PCI treatment guided by angiography alone, PCI treatment under the guidance of OCT can significantly improve patient prognosis. Subsequently, in the 2013 European Society of Cardiology Guidelines for the Management of Stable Coronary Heart Disease, OCT was listed as a IIb recommendation (level of evidence B) for evaluating lesion characteristics and optimizing stent implantation, and the overall level of evidence was equivalent to IVUS. In 2014, the European Society of Cardiology / European Association of Cardiothoracic Surgery (ESC / EACTS) Myocardial Revascularization Guidelines upgraded the recommendation level of OCT for optimizing PCI to a level IIa recommendation equivalent to IVUS. The ILUMIEN I study published in 2015 showed that OCT examination before and / or after PCI can affect the interventional treatment strategy of the operator. The results of the ILUMIEN II study showed that OCT was not inferior to IVUS in guiding stent expansion. With the continuous updating of OCT technology and the publication of more prospective research data, the status of OCT in the field of interventional diagnosis and treatment of coronary heart disease will surely be further enhanced.

[0005] The OCT catheter is composed of multiple sections, and catheters made of different materials need to be welded together. In order to ensure welding quality and improve production results, corresponding tooling needs to be designed to meet production requirements. Summary of the invention
