Accurate measurement to lumen diameter, area, the imaging to vascular wall and blood vessel implant structure, and then distinguish patch property and
For blood vessel implant（Support, filter, turn etc.）Evaluation.
Intravascular computed tomography (SPECT) system is to be based on intravascular optical coherence tomography（Optical Coherence
Tomography, OCT）The system of technology combination imaging catheter, OCT technology is as after intravascular ultrasound（Intravascular
Ultrasound, IVUS）Imaging technique in a kind of new coronary artery occurred afterwards, compared with IVUS, resolution ratio high OCT
It is set to evaluate vulnerable plaque, stenter to implant instructed, especially in acute coronary syndrome（Acute Coronary
Syndrome, ACS）Application in diagnosis and treatment is of increasing concern.
, American Society of Cardiology/American Heart Association in 2011（ACCF/AHA）To IVUS in Percutantnoeus coronary intervention guide
In percutaneous coronary intervention (pci)（Percutaneous Coronary Intervention, PCI）Recommendation of middle application etc.
Level is IIa, and the recommendation grade to OCT is not yet established because evidence-based medical is not enough.2012, CLI-OPCI researchs showed,
Compared with the PCI treatments that simple radiography is instructed, the PCI treatments under OCT is instructed can significantly improve patient's prognosis.Then, 2013
Year, European Society of Cardiology was in Stable coronary heart disease administration guide, OCT is for assessing characteristics of lesion and optimization stenter to implant
Process is classified as IIb grades of recommendations（Level of evidence is B grades）, overall evidence level is equal to IVUS.2014, heart of Europe disease was learned
Meeting/Europe cardiothoracic surgery association（ESC/EACTS）In myocardium revascularization guide, OCT is lifted to the recommendation grade for optimizing PCI
Recommend to the IIa levels being equal with IVUS.The ILUMIEN I researchs delivered for 2015 show that PCI is preoperative and/or postoperative row OCT inspection
The strategies of interventional treatment of patient can be influenceed by looking into.ILUMIEN II results of study show that OCT is not inferior in terms of stent expansion is instructed
IVUS.With the continuous renewal and the announcement of more perspective study data of OCT technologies, OCT is led in coronary intervention
Status in domain will further be lifted.
It is to connect OCT equipment and the key of optical fiber as the fibre-optic catheter of one of OCT technology key, is to ensure OCT equipment
The necessary guarantee of normal operation, the optical fiber of traditional OCT equipment is that rotation is driven by a transmission device, this driving
Mode causes system architecture complicated, and driving error is big, and volume is big, and control is complicated and noise is larger, it is necessary to improved.Wherein
The structure of interior card body is one of key technology again.
The content of the invention
The purpose of the present invention is to design a kind of fiber spinning formula OCT conduits that can be directly driven by core motor with interior card
Body.
The technical scheme is that：
A kind of interior card body of fiber spinning formula OCT conduits, it is characterized in that it is formed by symmetrical two parts clamping, blocks in every half
One side of body is provided with chucking hook 303, and another side is provided with the bottom of card body in neck 304, every half provided with half of O-shaped sealing of suit
The endless belt 301 of circle 2, elastic card body 313 is provided with the inside of interior card body, and optical fiber gland 5 is consolidated by two elastic card bodies 313
It is scheduled in interior card body and is rotated at a high speed with interior card body.
One side of card body is provided with positioning tooth 305 in described every half, and another side is provided with positioning teeth groove 306 to prevent interior card
Axial direction and radial misalignments after body buckle.
The lower end of the close O-ring of described elastic card body 313 and the folder of interior card body axial line one 10-15 degree of formation
Angle.
The lower end of the close O-ring of described elastic card body 313 forms one 11 degree of angle with interior card body axial line.
Beneficial effects of the present invention：
The present invention is simple in construction, and connection is reliable, changes convenient.Especially by elastic card claw realize optical fiber gland axial direction and
Radial positioning, it is simple and reliable.
