Abstract
The invention relates to a torsion testing device for a self-expanding support. A torsion test on the self-expanding support can be carried out, and torque and the number of times of torsion can be recorded. The torsion testing device comprises a motor, a body, a fixed seat, a connecting column, a torque induction device, a temperature control device and a torsion control device. The motor is mounted on the plane of the fixed seat. The torque induction device is mounted at the head end of the motor. The motor and the torsion control device are connected. The motor and the connecting column are fixed with the two ends of the support respectively. The torsion testing device is arranged in the environment of the temperature control device, and the temperature of the environment can be adjusted to 37 DEG C to simulate in-vitro tests of the support.
Description
Technical field
The present invention relates to a kind of self-expandable stent and reverse proving installation, belong 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.
Summary of the invention
The technical problem to be solved in the present invention 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 invention.
Fig. 2 is left view of the present invention.
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 invention below in conjunction with drawings and Examples, following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
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 limitation of the present invention, and the present invention is also not limited in above-mentioned citing, and 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 scope of the present invention.
