Description
Technical field
The utility model is related to a kind of medical examination apparatus, especially a kind of angiographic diagnosis technology, specifically
A kind of fiber spinning formula OCT conduits move back and forth low-loss drum with short distance antarafacial.
Background technology
Intravascular computed tomography (SPECT) system cooperation imaging catheter is designed for the imaging to the blood vessel of diameter > 1.5mm, realizes
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(Stent, filter, spring ring etc.)Evaluation.
Intravascular computed tomography (SPECT) system is based on intravascular optical coherence tomography(Optical Coherence
Tomography, OCT)The system of technology combination imaging catheter, OCT technology are used 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
Make it in evaluation vulnerable plaque, instruct stenter to implant, especially in acute coronary syndrome(Acute Coronary
Syndrome, ACS)Application in diagnosis and treatment is of increasing concern.
2011, American Society of Cardiology/American Heart Association(ACCF/AHA)To IVUS in Percutantnoeus coronary intervention guide
In percutaneous coronary intervention (pci)(Percutaneous Coronary Intervention, PCI)Recommendation of middle application etc.
Grade is IIa, and to the recommendation grade of OCT because evidence-based medical deficiency is not yet established.2012, CLI-OPCI research shows that,
Compared with the PCI treatments of simple radiography guidance, the PCI treatments under OCT guidances can significantly improve patient's prognosis.Then, 2013
Year European Society of Cardiology is about in Stable coronary heart disease administration guide, and OCT is for assessment lesion characteristics 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
Meeting/Europe cardiothoracic surgery association(ESC/EACTS)In myocardium revascularization guide, OCT promotes the recommendation grade for optimizing PCI
Recommend to the IIa grades being equal with IVUS.The ILUMIEN I that deliver for 2015 are research shows that PCI is preoperative and/or postoperative row OCT inspections
The strategies of interventional treatment of patient can be influenced 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 of OCT technologies and the announcement of more perspective study data, OCT is led in coronary intervention
Status in domain will further be promoted.
Catheter position can change OCT image equipment in use, and the fiber lengths of connecting conduit can become
Change, for this reason, it may be necessary to which optical fiber is accommodated in fiber termination box in advance, to carry out folding and unfolding in time, ensure the normal work of equipment, because
This, it is the task of top priority to design a kind of short distance optical fiber and move back and forth coiling box.
Utility model content
The purpose of this utility model needs to carry out the optical fiber outside conduit timely in the process for the use of OTC equipment
Folding and unfolding designs a kind of short distance antarafacial and moves back and forth low-loss drum.
The technical solution of the utility model is:
A kind of short distance antarafacial moves back and forth low-loss drum, it is characterized in that the tail portion that it includes a whistle shape pedestal 1 is set
There is the cabling channel 2 for fiber optic disc around, the input end of cabling channel 2 is connected to form fiber entrance with the mouth of whistle shape pedestal 1, cabling
The port of export of slot 2 is equipped with partition board 3, and optical fiber enters in cabling channel 2 from input end and enters partition board 3 from product end, and under partition board 3
The outlet notch 4 in portion exports.
The lower part of the whistle shape pedestal 1 is connected with support feet 5.
Anti-drop tooth 6 is equipped in the cabling channel 2.
The beneficial effects of the utility model:
The utility model is simple in structure, acts freely, and loss is low, easy to use.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1.
A kind of short distance antarafacial moves back and forth low-loss drum, and the tail portion that it includes a whistle shape pedestal 1 is equipped with for optical fiber
The cabling channel 2 of coiling, the input end of cabling channel 2 are connected to form fiber entrance with the mouth of whistle shape pedestal 1, and cabling channel 2 goes out
Mouth end is equipped with partition board 3, and optical fiber enters in cabling channel 2 from input end and enters partition board 3, and going out from 3 lower part of partition board from product end
Line notch 4 exports.The lower part of the whistle shape pedestal 1 is connected with support feet 5.Anti-drop tooth 6 is equipped in the cabling channel 2, is prevented
Debentition 6 is the design for preventing optical fiber cable from coming off from notch after installing.
Cabling channel 2 is the notch of fiber optic disc around, size directly determine minimum of the optical fiber cable in notch can bending it is straight
Diameter, parameter and the loss of optical fiber cable after installation are closely related;
That is notch diameter D:
1. when D is bigger, the optical fiber cable coil diameter of notch installation is bigger, and loss is lower;
2. when D is smaller, the optical fiber cable coil diameter of notch installation is smaller, and loss is higher;
3. when D diameters are less than optical fiber cable minimum breaking diameter, optical fiber cable damage.
In addition, to facilitate installation, support feet 5 is equipped with mounting hole 7, mounting hole 7 is the required design of fixed mechanism,
Partition board 3 is to prevent from designing into out optical fiber line winding.
It is same as the prior art or the prior art can be used realized that the utility model is not directed to part.
