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.
In OCT conduit manufacturing processes, need to punch two ends of the hose outside conduit, for preparation into
Go out, and traditional punching collet is there are the problems such as volume is big, punching chip cleaning is difficult, therefore has and must be improved.
Utility model content
The purpose of this utility model, which is directed in OTC conduit manufacturing processes, to be needed to punch outermost hose, and lacks phase
The problem of drilling tool answered, designs a kind of punching with concave-convex collet.
The technical solution of the utility model is：
A kind of concave-convex collet of punching, it includes elastic collet 1, mounting cylinder 2 and locking nut 9, the installation of elastic collet 1
End is inserted into mounting cylinder 2, and locking nut 9 on mounting cylinder 2 and oppresses elastic collet tightening by screw thread spinning, realizes perforating needle
Clamping；It is characterized in that one end of the fixed seat 8 of the elastic collet 1 is connected with 12 elastic card claws 3, the other end, which is equipped with, to be inserted
Enter the bulge-structure 5 in mounting cylinder circumferential direction notch 4；The hole for being inserted into perforating needle 7 is equipped at the center of the fixed seat 8 of elastic card claw 3
Slot 6, one end of perforating needle 7 are inserted into the hole slot 6, and the other end is by 12 3 self-centering clampings of elastic card claw, in fixed seat 8
Offer the cleaning through-hole 11 entered for elastic alloy wire 10 for clearing up chip in perforating needle 7, cleaning with through-hole 11 with
Hole slot 6 connects.
The mounting cylinder 2 be in cylindrical structure, its one end open up there are three on elastic collet 1 bulge-structure match
And the circumferential notch 4 engaged.
The 11 arc-shaped structure of cleaning through-hole is to facilitate the entrance of elastic alloy wire 10.
The perforating needle 7 is hollow needle.
The beneficial effects of the utility model：
The utility model is simple in structure, small, and centering precision is high, and chip cleaning is convenient, can without removing perforating needle
Realize cleaning.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in figs 1-9.
A kind of concave-convex collet of the punching used in OCT pipes manufacture, it includes elastic collet 1（Fig. 1）, mounting cylinder 2（Fig. 6,
7）With locking nut 9（Fig. 9）, the installation end of elastic collet 1 is inserted into mounting cylinder 2, and locking nut 9 is being installed by screw thread spinning
On cylinder 2 and elastic collet tightening is oppressed, realizes the clamping of perforating needle, as shown in Figure 8；It is characterized in that the elastic collet 1
One end of fixed seat 8 is connected with 12 elastic card claws 3（Fig. 3）, the other end is equipped with three be inserted into the circumferential notch 4 of mounting cylinder 2
Bulge-structure 5（Fig. 4）, mounting cylinder 2 be in cylindrical structure, its one end open up there are three with the bulge-structure phase on elastic collet 1
The circumferential notch 4 matched and engaged；The hole slot 6 for being inserted into hollow perforating needle 7 is equipped at the center of the fixed seat 8 of elastic card claw 3（Figure
2）, one end of perforating needle 7 is inserted into the hole slot 6, and the other end is opened by 12 3 self-centering clampings of elastic card claw in fixed seat 8
Equipped with supplying elastic alloy wire 10 for clear up chip in perforating needle 7（Structure such as Fig. 5, one end carry hand held structures）What is entered is clear
Reason through-hole 11, cleaning through-hole 11 connect with hole slot 6；
During installation, perforating needle is first inserted into collet, then nut coordinates with collet, is inserted into mounting cylinder, tightening nut
9, three is fixed together, while collet clamps perforating needle 7, and collet uses 12 pawls, and compared with traditional 6 claw clip heads, concentricity is more
Height, chuck portion are connect using special-shaped hole slot, one end with perforating needle, improve the concentricity of needle（It prevents from clamping at the top of collet
