A kind of outer card body of fiber spinning formula OCT conduits.
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.
Fibre-optic catheter as one of OCT technology key is the key that connection OCT equipment and optical fiber, is to ensure OCT equipment
The necessary guarantee of normal operation, the optical fiber of traditional OCT equipment are to drive rotation, this driving by a transmission device
Mode causes system structure complicated, and driving error is big, and volume is big, and control is complicated and noise is larger, it is necessary to be improved.And make
One of key for improved conduit is the design and manufacture of outer card body.
Utility model content
The purpose of this utility model, which is that design is a kind of, to be used by the fiber spinning formula OCT conduits that core motor directly drives
Outer card body.
The technical solution of the utility model is：
A kind of outer card body of fiber spinning formula OCT conduits, it includes outer card body 1, it is characterized in that the one of the outer card body 1
The large end face 106 at end is equipped with the wild card for being connect with OCT equipment and being clamped and being connected and turns tooth 102, the large end face 106 and interior card body 3
Outer 302 offsets, and is installed in the hollow positioning column 101 hollow positioning column 101 that is internally provided with of outer card body 1 with interior 3 lower end of card body
There is O-ring 2 to offset, the other end of outer card body is connected with tail pipe 107, and tail pipe 107 connects with hollow positioning column 101, in tail pipe
107 tail end is equipped with engraved structure 105.
The centre position of the outer card body 1 is equipped with and prevented from inserting and the positioning retainer ring 103 using hand-held.
The handheld terminal of the outer card body 1 is equipped with non-slip groove.
The engraved structure 105 forms engraved structure by the slot at 90 degree of intervals.
The beneficial effects of the utility model：
The utility model is simple in structure, and connection is reliable, and it is convenient to replace.The cylindricality knot that especially fixed optical fiber gland uses
Structure is axially and radially located by elastic card claw realization, simple and reliable.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the utility model using state structure diagram.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figs. 1-2.
A kind of outer card body of fiber spinning formula OCT conduits, it includes outer card body 1, such as Fig. 1, one end of the outer card body 1
Large end face 106 be equipped with the wild card being clamped with OCT equipment or 4 phase of dustproof cover and turn tooth 102, wild card turns the quantity of tooth 102 at least
It for 4 and is distributed on large end face 106, the outer 302 of the large end face 106 and interior card body 3 offsets, such as Fig. 2, in outer card body 1
Be internally provided with the hollow positioning column 101 hollow positioning column 101 O-ring 2 be installed with interior 3 lower end of card body and offset, outer card body it is another
One end is connected with tail pipe 107, and tail pipe 107 connects with hollow positioning column 101, and engraved structure is equipped in the tail end of tail pipe 107
105.The centre position of the outer card body 1 is additionally provided with the positioning retainer ring 103 for preventing from inserting and using hand-held.Described is outer
The handheld terminal of card body 1 is equipped with non-slip groove.The engraved structure 105 forms hollow out knot by the slot at 90 degree of intervals
Structure.
The effect of outer card body：
1st, protective effect.Internal component is protected during production, packaging, transport, storage, use.
2nd, handheld component.Handheld component of the wild card as operation Shi doctor, inserts the catheter into intervention by capturing wild card and sets
It is standby.
3rd, recognition reaction is connected.Intervening equipment is inserted on outer card body head in use, and is identified by equipment.Identify it
Subsequent intervention operation can be just carried out afterwards.
4th, connection function.Wild card tail portion needs the buckle pipe of connecting conduit.
The specification of wild card（Such as Fig. 1）：
1st, wild card turns tooth 102.Conduit rotates clockwise certain angle after being inserted into equipment or dustproof cover, and wild card turns tooth turn at this time
Dynamic facility switching of stirring is by machine recognition, while the positioning groove of equipment（It is similar with dustproof cover）It blocks wild card and turns tooth.It is therefore outer
Card turns tooth and plays the role of two：It is fixed, identified.
2nd, positioning retainer ring 103.For conduit when being inserted into equipment, positioning retainer ring is both hand-held stop portions（Before preventing finger
It is sliding）, and be the limit part being inserted into（Define that conduit is inserted into the distance of equipment）.
3rd, non-slip groove.Handgrip part when non-slip groove is operation, concave-convex groove increase the frictional force of hand, side
Just finger manipulation.
4th, hollow out tail pipe 105.Tail pipe has done hollow processing facing with what side view was respectively separated.It was produced in this way in conduit
Not only the bonding with bayonet tube had been facilitated in journey, but also in operation carries out, be free to be bent, be conveniently operated.
It is same as the prior art or the prior art can be used realized that the utility model is not directed to part.
