Description
Affiliated field
The present invention relates to support constrictor, particularly Centre-symmetric conjugate cylinder network frame equal diameter contractor.
Background technology
Human blood vessel kind disease such as coronary stricture, cerebrovascular is fastened plug, has been pharmacotherapy or traditional operation therapy since hemangioma etc. are long-term.Introduced since the biomedical engineering technology, all kinds of cylinder networks based on the research and development of biomedical engineering science are widely used in above-mentioned treatment of diseases and demonstrate its superior curative effect.During this biomedical engineering technology is used, important key technology is to be retracted on the sacculus induction system the cylinder network is isometrical, so that utilize the sacculus induction system that the cylinder network is accurately delivered to diseased region, and be located on blood vessel.This key technology success or not has influence of the utmost importance to medical effect.Early stage, technology was the simple hand instrument, caused non-isometrical contraction of cylinder network or torsional deformation easily.Though the later stage tab style iso-radius contractor for cylindrical reticular stent technology of development has had large increase than hand tools, but still there is fin and tightened and produce the tangential component of stress between support, influence the deflation assembly quality of support, require the new know-why of research further to improve.
Summary of the invention
The present invention seeks to provides a kind of Centre-symmetric conjugate cylinder network frame equal diameter contractor at the prior art defective, solves described key problem in technology.It is 80-116um that the cylinder network adopts wall thickness usually, and diameter is that the medical stainless steel pipe of 1.6mm is engraved through the digital control laser precision and made.Its length is that 20-45mm does not wait, and requires to decide according to patient's sign and diseased region.The strictness of the netted support Design structure of cylinder is according to blood vessel kinetics, biomechanics, and the Elasticity calculating data, the appliance computer Aided Design forms.Its design guarantee cylinder network radial tension each to evenly, franchise is less than 0.1%.Global design and laser accurate processing technique have guaranteed that the cylinder network has propelling movement property in the good blood vessel, compliance that blood vessel passes through and bendability.The purpose of this invention is to research and solve the key problem in technology of the isometrical contraction of cylinder network, promptly tighten to carrying on the sacculus the cylinder network is isometrical by the biomedical engineering designing requirement, in process of packing, make support all radial forces on whole barrel surface even, the distortion that is not distorted keeps its original design and make performance.
According to the netted supporting structure mechanics feature of cylinder, design is the continuous transformation diameter arbitrarily, simultaneously the support that is tightened only there is the centrosymmetry conjugation mechanism of radial effect power, produces uniform radial force and act on the cylinder network external cylindrical surface, make its isometrical contraction.According to the mechanical engineering principle, design centre symmetry conjugate tooth makes its quadrant block of accurately controlling in each slide guide track synchronously entad do or centrifugal moving along track.When n (n is an even number) quadrant block synchronously when track moves to the center, the secter pat gap-closing makes center-hole diameter be reduced to d.
Centre-symmetric conjugate cylinder network frame equal diameter contractor, comprise body 1, quadrant block 2 and conjugate tooth 3, it is characterized in that establishing n guide rail in the body 1, be provided with n quadrant block 2 in the track, one side of quadrant block 2 is provided with the control pin, and this pin is assemblied in the cotter way of conjugate tooth 3; When conjugate tooth 3 turns clockwise, n the active force entad motion synchronously that quadrant block 2 is produced by conjugate tooth 3 cotter ways; When conjugate tooth 3 is rotated counterclockwise, n the synchronous centrifugal motion of active force that quadrant block 2 is produced by conjugate tooth 3 cotter ways; Establish a supporting plate 7 at the top of quadrant block 2, be fixed on the quadrant block 2 by bolt 8; It is located at the holder power that the spring 5 in body 1 spring 5 grooves makes progress all the time; Distance collar 6 is assemblied on the axle of body 1, and it is fastening by end cap 4, seals into rectangle with guide rail on the body 1, guarantees the accurate movement locus of quadrant block 2; Conjugate tooth 3 is linked on the distance collar 6, serve as the axle rotation with distance collar 6, and distance collar 6 can guarantee that conjugate tooth 3 both sides have rotary gap.
Turn clockwise when driven wheel 9 drives conjugate tooths 3, the top active force of conjugate tooth 3 cotter ways is in the bearing pin of quadrant block 2, overcomes the holder power that spring 5 makes progress quadrant block 2 is entad slided.The face of cylinder diameter of 2 envelopes of n quadrant block diminishes continuously, when quadrant block 2 closures, promptly reaches the cylinder network and tightens the diameter d that requires at last.
Be rotated counterclockwise when driven wheel 9 drives conjugate tooth 3, the lower reaction power of conjugate tooth 3 cotter ways makes quadrant block 2 return to initial position under spring 5 auxiliary force combineds effect simultaneously in the bearing pin of quadrant block 2.
Centre-symmetric conjugate cylinder network frame equal diameter contractor constructed in accordance is used in biomedical engineering reality, and effect is remarkable.The practical application proof has the advantage of following uniqueness:
1, meets design requirement as long as make, this inventive principle makes cylinder network and system thereof not be subjected to any additional force in isometrical process of packing, guarantee that the cylinder network only is subjected to the radial force of cylindrical radial face in the secter pat, guarantee that the isometrical contraction of cylinder network meets technical performance requirement original design and that make.
2, the inboard cylindrical radial face of secter pat equates that with the face of cylinder, the cylinder network outside curvature that is tightened the external cylindrical surface of cylindrical radial face and support all coincide at the deflation initial stage.The support external cylindrical surface evenly is subjected to radially, and the area of constrictive force reaches more than 90%.Successively decrease in process of packing medium-height trestle external cylindrical surface curvature, separate with the support external cylindrical surface gradually cylindrical radial face both sides in the secter pat.Finish to tightening, calculate by theoretical, the Separation of cylindrical radial face and support external cylindrical surface two-end-point is 0.0041mm in the secter pat, is decremented to 15 ° of angle positions of cylindrical radial face, only is 0.002mm.Consider the strain of cylinder network in process of packing, can think this invention technology of using, can make coghill net shape support external cylindrical surface in whole process of packing all the time with tighten that the cylindrical radial face coincide in the device secter pat.In the isometrical contraction technology of present known cylinder network, still there is not this level that reaches.
3, because the driving wheel of this design can adopt manual control also can adopt the numerical control step motor drive, therefore good interface capability is arranged with the numerical control manufacturing.
