The motor is installed on the fixing base plane, moment of torsion induction system adorns in the motor head end, the motor with twist reverse controlling means and be connected, the motor is fixed with the both ends of support respectively with the spliced pole. The utility model discloses arrange the temperature control device environment in, can transfer ambient temperature and test outside 37 DEG C are simulated the stake body.
Description
Technical field
The utility model relates to a kind of self-expandable stent and reverses proving installation, belongs to technical field of medical instruments.
Background technology
The interventional therapy of peripheral artery disease, the vigorous professional technique as a kind of youth, just in develop rapidly, in very large range can substitute operation.21 century, the chamber intervenien therapy of angiosis was vascular surgery development one of Main way.The scope of the interventional therapy of peripheral artery disease develops into main artery and vein from original limb artery, the blood vessel that even whole body is nearly all.The most successfully the interventional therapy of ilium, femoral artery, the arteria renalis and IVC stenosis at present.Scope mainly hemadostewnosis or the large class disease of obturation, blood vessel dilatation and vascular malformation 3 of interventional therapy.
Since the sixties in 20th century dotter be since 83 years old woman of a trouble arterial obliterans of lower extremity implements PTA (Percutaneous intravascular embark on journey art) in the world first, the technology of peripheral artery disease interventional therapy and means development very fast; Especially early 1990s parodi initiates the milestone that chamber intervenien therapy abdominal aneurvsm is more endoluminal vascular surgery.Compared with traditional vascular operation, it is little that the interventional therapy of angiosis has wound, the advantages such as complication is low, and the hospital stays is short.
Self-expandable stent moves with human body after entering human vas, can run into various support being subject to some large impact ， popliteal artery places due to external power as: arteria carotis place blood vessel occasional from outside and inner resistance along with the motion of health does the bending and distortion gone round and begun again.The torsional resistance of self-expandable stent directly has influence on support in the security of human body and the serviceable life at support itself, and the torsion test therefore for support is absolutely necessary.The process that present stage tests for self-expandable stent twisting property is too loaded down with trivial details, and dirigibility is not high.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of self-expandable stent and reverses proving installation, and this device is placed in attemperating unit, environment temperature can be adjusted to 37 DEG C.
For achieving the above object, the technical solution used in the present invention is:
A kind of self-expandable stent reverses proving installation, it is characterized in that the torsion test can carrying out self-expandable stent, and moment of torsion and number of torsions can be recorded, comprise motor, main body, holder, joint pin, moment of torsion induction installation, attemperating unit, twist control.Described motor is arranged in holder plane; Described moment of torsion induction installation is loaded on motor head end; Described motor is connected with twist control; Described motor and joint pin are fixed with the two ends of support respectively.
Preferably, the spacing of described holder and joint pin is adjustable, and adjustable extent is 0 ~ 250mm.
Preferably, described motor speed is adjustable, and adjustable extent is 0 ~ 30r/s.
Preferably, the moment of torsion of support when described moment of torsion induction installation can show test in real time, and the maximal value of moment of torsion in stipulated number can be recorded.
Preferably, described twist control can set number of torsions and windup-degree, and angular range is 0 ~ 180 °.
Preferably, described twist control can catch the moment of torsion that moment of torsion induction installation records, and display is recorded in real time.
Preferably, the adjustable test environment temperature of described attemperating unit, adjustable extent is 1 DEG C ~ 50 DEG C.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model left view.
Fig. 3 is for carrying out support torsion test structure schematic diagram.
Wherein, 1 be motor, 2 be holder, 3 be moment of torsion induction installation, 4 be main body, 5 be joint pin, 6 be twist control, 7 for attemperating unit.
Embodiment
Be described further enforcement of the present utility model below in conjunction with drawings and Examples, following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, motor 1, holder 2, moment of torsion induction installation 3, main body 4, joint pin 5, twist control 6, attemperating unit 7 have been the present invention includes.
Described motor 1 is arranged in holder 2 plane; Described moment of torsion induction installation 3 is loaded on motor 1 head end; Described motor 1 is connected with twist control 6; Described motor 1 is fixed with the two ends of support respectively with joint pin 5.Attemperating unit 7 is enclosed within whole device, plays sealing thermal insulation effect.
Carry out the twisting property test of self-expandable stent as shown in Figure 3, support two ends are bundled in respectively on moment of torsion induction installation 3 and joint pin 5, start attemperating unit 7, environment temperature is set to 37 DEG C.Start twist control 6, windup-degree is arranged to ± 45 °, torsion frequency is arranged to 1s/ time, and arranging number of times is 10000 times.Twist control can show the moment of torsion of the number of times reversed and the support recorded in real time, judges whether the twisting property of support can reach requirement with this.
Above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing; the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
