Background technique
Annulus expansion is atrioventricular valve (including bicuspid valve, tricuspid valve) most common cause of disease, it can cause leaflet to be divided mutually
From, generate gap and lead to valvular regurgitation.Therefore, for annulus expand and carry out annulus ring contracting art (including suture annulus, plant
Enter prosthetic valve ring etc.) be bicuspid valve or tricuspid valve reparation important art formula, and basic art formula.Current bicuspid valve, tricuspid valve
Recovery technique be all annulus ring contracting art on the basis of, combine other recovery techniques (as leaflet reparation, chordae tendineae are implanted into) complete.It
Principle be to be directed to incompetence caused by annulus is expanded, make leaflet by reducing bicuspid valve or tricuspid valve valve orifice area
It can mutually fit, to reduce reflux, even completely eliminate reflux.
Although surgical operation can be very good to repair mitral annulus, it is big with wound, risk is high, patient restores
The disadvantages of slow.In recent years, the concept to contract through conduit annulus of mitral valve is come into being.It is not stopped by interventional minimally-invasive mode in heart
In the case of jump, ring contracting is carried out to bicuspid valve using instrument.Although having some this respect instruments, safety validity in the world
It is not sufficiently verified, and in the prevalence of disadvantage inconvenient for operation.

Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
A kind of annulus constrictor shrinks for annulus through catheter manipulation, including fixing glue 1, nailed apparatus 2, connecting line 3, beats
Tie device and thread cutter.
As depicted in figs. 1 and 2, fixing glue 1 includes spiral needle 1-1 and fixing head 1-2.Spiral needle 1-1 is screw type needle, head
End is sharp, is made of rigid materials such as metal materials, the outer diameter 2-4mm of spiral circle, vertical length 4-8mm.
Fixing head 1-2 is generally cylindric, including the nearly heart section fixed for spiral needle 1-1, intermediate spiral section 1-2-2
With distal end rotation section 1-2-1.The nearly heart Duan Bingxiang proximal part that spiral needle 1-1 is fixed on fixing head 1-2 stretches out.Spiral section 1-
2-2 is external thread structure, is matched with the internal screw thread of nailed apparatus outer tube 2-1 inner wall setting, this section of outer diameter is equal to or is greater than
The outer diameter of spiral needle 1-1.Rotation section 1-2-1 be a rectangular sheet structure, be arranged with the rotation push piece 2-2 proximal part of nailed apparatus 2
Groove structure match, by rotation revolve push piece 2-2, drive rotation section 1-2-1 rotate, can then drive entire fixing glue
1 (including spiral needle) rotation, spiral needle 1-1, which can be transferred to, to be followed closely into tissue.Rotation section 1-2-1 be additionally provided with wiring hole 1-2-3,
Connecting line 3 is connect by wiring hole 1-2-3 with fixing head 1-2.Fixing head 1-2 can be made of stainless steel and other metal materials, can also
To be made of the high molecular material of hard.
As shown in Figures 3 and 4, nailed apparatus 2 includes outer tube 2-1 and rotation push piece 2-2.Outer tube 2-1 divides from proximal part to distal end
Not Wei cavity segment, thread segment and conveying section, cavity segment can accommodate the spiral needle 1-1 of fixing glue 1, so that spiral needle 1-1 is just
Outer tube 2-1 is not exposed, thread segment is equipped with internal screw thread, matches with the external screw thread of the spiral section 1-2-2 of fixing glue 1, and conveying section is sky
Heart lumen can accommodate the rotation conveying of rotation push piece 2-2.
Rotation push piece 2-2 proximal part is set as groove structure 2-2-1, can match with the flake structure of rotation section 1-2-1,
Push piece 2-2 is revolved by rotation, the principle of screw is tightened with similar straight screwdriver, fixing glue 1 is driven to rotate.It revolves in push piece 2-2
Portion is equipped with the perforation passed through for connecting line 3.Fixing glue 1 is assemblied in outer tube 2-1 and cooperates with rotation push piece 2-2 outside when nailing
Pipe 2-1 proximal part precession, when fixing glue 1 rotates, spiral section 1-2-2 is screwed out from the thread segment of outer tube 2-1, while spiral needle
1-1 also hammers into tissue.Recession nailed apparatus 2 later can make nailed apparatus 2 and fixing glue 1 be detached from.Nailed apparatus 2 is by high score
Sub- material is constituted, and integrally can be straight tube-like, and nearly heart section can also advantageously allow to beat in fixed curved or adjustable bending structure, the latter
After nail device 2 enters heart, nearly heart section improves the effect that fixing glue 1 screws in tissue perpendicular to annulus tissue.
Connecting line 3 is by the high molecular materials such as nylon, polyethylene, polypropylene or titanium-nickel wire, stainless steel wire and metal tantalum wire
Equal metal materials are constituted.Connecting line 3 is connected in the wiring hole 1-2-3 of fixing glue 1, by drawing the company in several fixing glues 1 over to one's side
Wiring 3, the distance between fixing glue that can further 1, thus the tissue that the fixing glue 1 that furthers hammers into.
Optionally, as seen in figs. 5-6, the annulus constrictor further include using can endothelialization high molecular material (such as PET film/
Soft silica gel etc.) made of protective cap 4, protective cap 4 is in bowl-type and distal end is equipped with and matches assembly with rotation section 1-2-1 structure
Hole 4-1 is not in fall off when it is covered in fixing glue 1.1 nailing of fixing glue in place after, protective cap 4 is sent along connecting line 3
To the position of fixing glue 1, protective cap 4 on rotation section 1-2-1 and covers spiral section 1-2-2 by pilot hole 4-1 encapsulation, makes solid
Surely nail 1 avoids thrombotic risk from exposure in blood.Then, protective cap endothelialization, so that whole device avoids exposure to blood
In liquid, thrombotic risk is avoided.Protective cap can be set in nailed apparatus 2, be also possible to absolute construction, squeeze into after fixing glue 1 by
Particular conveying systems, which incorporate, reaches fixing glue 1.
Knotter and thread cutter can be implemented by using the prior art, and specific embodiment is not unique, and which is not described herein again.
The use process of the annulus constrictor is as is seen in figs 7-10.When surgical procedure, fixing glue 1 is packed into nailed apparatus 2, it will
Nailed apparatus 2 reaches the atrial surface of bicuspid valve or Tricuspid annulus along human vas or punching point, adjusts the outer tube of nailed apparatus 2
2-1 drives solid so that the telecentricity section of nailed apparatus 2 is vertical or approximately perpendicular to annulus tissue, rotates the rotation push piece 2-2 of nailed apparatus 2
Fixing glue 1 is hammered into annulus tissue by 1 rotation of nail surely, and nailed apparatus 2 of dropping back stays in the fixing glue 1 with connecting line 3 in human body.
It repeats above operation, hammers into second fixing glue 1 to neighbouring annulus tissue.Connecting line 3 is drawn over to one's side, it, will even using knotter
The tightening of wiring 3 knots, and the tissue where two fixing glues 1, which can be realized, to be drawn close.Use thread cutter by extra connecting line later
Interruption, such as Figure 10.When squeezing into multiple fixing glues 1, will the connecting line 3 of multiple fixing glues 1 mutually tense collapse after connect or
Gathering is tensed after interconnection again, the ring contracting of annulus can be realized.
" proximal part " occurred in present invention narration refers to close to annulus tissue or even hammers into one end of annulus tissue, " remote
Heart end " refers to the other end far from annulus tissue, the directive property of " nearly heart section " and " telecentricity section " respectively with " proximal part " and " telecentricity
The directive property at end " is consistent, and it is above-mentioned used by directionality vocabulary, be the description that uses based on convenience, be not to this hair
Bright limitation.
