Description
Technical field
The present invention relates to a kind of synchronous testing device for testing orthotopic fenestration fabric overlay film bursting and tear resistance.
Background technology
EVAR is little with its wound, recover fast, the advantage of few intercurrent disease, has evolved into aortic aneurysm class disease
Mainstream therapies.Therefore the crucial apparatus overlay film frame that this therapy is used have also been obtained fast development.Overlay film frame be by
Fabric overlay film and metal rack, through the medical apparatus and instruments that silk sutures connects as one.But for sudden aorta
For tumor wound, tumor body anatomic form complexity, aortic aneurysm adjoin the refractory aneurysms patient of important branch tremulous pulse, above-mentioned tradition
Overlay film frame the most applicable.But along with the development of Endovascular, " the orthotopic fenestration technology " of overlay film frame solves
State problem.The orthotopic fenestration of so-called overlay film frame, after i.e. discharging overlay film frame at refractory aneurysms, to overlay film frame just to dividing
Prop up the position of arterial accent, use apparatus of windowing that fabric overlay film carries out pricker and puncture and sacculus expansion so that in aorta
Blood flow can through opening flow into bifurcated artery, to guarantee the blood perfusion of important branch tremulous pulse.The advantage of this technology is
May be used for Emergency Assistance, become overlay film frame already in American-European countries at present and window the study hotspot of aspect.
Clinical research shows, although the middle or short term of orthotopic fenestration art respond well, but its long-term results is the most uncertain,
The durability of overlay film frame after windowing is worried by surgeon, and has clinical report: the instability of orthotopic fenestration may be led
Cause the inefficacy of overlay film frame.In view of clinicing aspect propose for the worry of overlay film frame after orthotopic fenestration, experts and scholars launch
A series of researchs, it is indicated that after orthotopic fenestration, overlay film frame is primarily present three problems: the excessive tear of fabric overlay film, opening
The yarn at edge, hole dissipates limit, and the metal rack fracture that instability of windowing causes.It is therefore desirable to orthotopic fenestration with knitting
Thing overlay film carries out while external emulation windows, and the stressing conditions of fabric overlay film during test orthotopic fenestration, to evaluate original position
Window and use the endurance quality of fabric overlay film, and then provide theoretical and technical support for optimizing orthotopic fenestration fabric overlay film.
Puncture via pricker before this when overlay film frame is windowed in position, to form tiny pinprick on fabric overlay film
Hole, is followed by placed in sacculus in acupuncture hole, and the expansion by sacculus makes Different Tear Test to target aperture size.Whole
During individual, fabric overlay film is first affected by the bursting effect of pricker, is followed by caused knit by the circumferential expansion effect of sacculus
The tear of thing overlay film.And existing mechanics test device also cannot accomplish that on-line testing fabric covers in dynamic in-situ windowing-process
The bursting of film and Tear strength.And only the overlay film frame fabric overlay film after orthotopic fenestration is carried out single bursting or tear survey
Examination all can not truly reflect and evaluate bursting and the tear resistance of orthotopic fenestration fabric overlay film, more cannot accurate evaluation in vitro
The endurance quality of fabric overlay film.By literature search, at home and abroad there is no about the mechanics test device simulating orthotopic fenestration
Research, and domestic in terms of bursting, the research of China Patent Publication No. CN104568579A and CN204630819U is only for biography
The sample of system textile accommodates the design of device, it is impossible to be suitable for and the true complicated applied force mistake reflecting orthotopic fenestration fabric overlay film
Journey.
Summary of the invention
It is an object of the invention to: design the synchronism detection dress of a kind of orthotopic fenestration fabric overlay film bursting and tear resistance

Present invention also offers the synchronous detecting method of above-mentioned a kind of orthotopic fenestration fabric overlay film bursting and tear resistance,
It is characterized in that, testing procedure is:
The first step, installs variable diameters probe assembly.By pin, first variable diameters probe assembly 201/202 one end is connected
And it is fixed to the lower end of the clamping assembly 301 of variable diameters probe assembly；Then connection is had variable diameters probe assembly 201/202
The upper end of clamping assembly 301 is fixed on multi-functional strength and elongation instrument.
Second step, installs sample.Straighten through probe assembly 201 as used, then fabric overlay film is positioned over lower specimen holder 402
On；Then upper specimen holder 401 is covered thereon and put into the lower clamping device 502 of specimen holder, and guarantee the prominent of upper specimen holder
In the groove 502d of the lower clamping device 502 that end 401d embeds specimen holder；Screw the upper clamping device 501 of specimen holder again；Finally,
The clamping device up and down 501/502 of specimen holder is fixed on the bottom of multi-functional strength and elongation instrument.
As used the variable diameters probe assembly 202 of band blade, can adjust between blade 202d-N and fabric overlay film warp thread
Cutting angle, will be positioned on the inner surface 402a of lower specimen holder 402 by fabric overlay film, adjust warp thread and make it with lower specimen holder
On the rule 402f of 402 inner surfacies, corresponding angle overlaps (i.e. cutting angle)；Then cover specimen holder 401, and guarantee
The jag 401d of upper the specimen holder 401 and vertical mark line 402g of lower specimen holder 402 aligns (the i.e. void region of specimen holder
401e/402e aligns)；Upper and lower specimen holder 401/402 is put into the lower specimen holder device 502 of specimen holder again, and guarantees upper sample
(the i.e. void region of specimen holder in the groove 502d of the lower clamping device 502 that the jag 401d of folder 401 embeds specimen holder
401e/402e aligns with the void region 502e of the clamping device of specimen holder)；Screw the upper clamping device 501 of specimen holder again, and
Guarantee vertical mark line 501c/502c alignment (the i.e. vacancy section of specimen holder of clamping device up and down 501/502 side of specimen holder
The void region 501e/502e alignment of the clamping device of territory 401e/402e and specimen holder)；Meanwhile, by upper clamping device 501
