Specific embodiment
In order that the present invention can be more clearly and readily understood, right below according to specific embodiment and in conjunction with attached drawing
The present invention is described in further detail.
Embodiment 1:
Refering to Figure 1, present embodiments providing a kind of flexible recyclable puncture anchor fixator, including U-shaped structure
It ontology 100 and is arranged and the retainer spring 200 on U-shaped structure ontology 100.
Material of the U-shaped structure ontology 100 using having elasticity and suitable for deformation is made so that the U-shaped structure ontology 100 is suitable
In deformation；One end of U-shaped structure ontology 100 is closed arc end 101 and the other end is open end 103.Retainer spring 200
103 peripheral side of open end of U-shaped structure ontology 100 is sheathed on to collapse the open end 103 of the U-shaped structure ontology 100.
Optionally, the material that U-shaped structure ontology 100 is made is NiTi alloy.NiTi alloy is a kind of flexible material
Matter, in this way, fixator is made to generate deformation under the traction action of push silk 400.
It should be noted that the U-shaped structure ontology 100 of the present embodiment is bent to form U-shaped structure using linear material, because
The both ends of this U-shaped structure ontology 100 that can be formed after bending respectively constitute closed arc end 101 and open end 103, fixed
The effect of spring 200 predominantly forms the effect that constraint is collapsed to open end 103.U-shaped structure is accounted for for 200 amount length of retainer spring
The 1/3~1/2 of 100 entire length of ontology can meet the constraint for the open end 103 of U-shaped structure ontology 100 and collapse effect.
And retainer spring 200 itself also has elasticity, and therefore, retainer spring 200 is realizing the open end 103 for U-shaped structure ontology 100
Constraint collapse effect on the basis of, not only will not influence fixator and deformed with the drawing of push silk 400, but also can be with
The deformation of fixator, which synchronizes, to be badly deformed.
For the connection relationship between retainer spring 200 and U-shaped structure ontology 100, retainer spring 200 and U-shaped structure ontology 100
Riveting is connected by high viscosity viscose glue, certainly also optional, real by welding between retainer spring 200 and U-shaped structure ontology 100
Now between the two be connected.
Embodiment 2:
Refering to Figure 1, the present embodiment mentions on the basis of the flexibility of embodiment 1 recyclable puncture anchor fixator
A kind of flexible recyclable puncture anchor is supplied, specifically include: what the arc end 101 of the fixator of embodiment 1 and fixator was connected returns
Take-up 300, and partly it is fixed on the push silk 400 inside the U-shaped structure ontology 100 of fixator.Wherein, exhausting line 300
For soft line.
Specifically, being formed with a channel 105, the channel 105 between open end 103 and arc end 101 in U-shaped structure body
It is to be formed during being bent to form U-shaped structure by linear material.Push the portion that silk 400 and U-shaped structure ontology 100 are connected
Partial volume is contained in channel 105；The inner sidewall for pushing the channel 105 of silk 400 and U-shaped structure ontology 100 is connected；Push silk 400 and U
Shape structural body 100 be connected part the nearly U-shaped structure body in end open end 103.
Optionally, push silk 400 is connected by the way of such as, but not limited to welding with the inner sidewall in channel 105.Push
The end of silk 400 is optional to be flushed with the open end 103 of U-shaped structure body, also optional, pushes end and the U-shaped structure body of silk 400
Open end 103 do not flush, such as be contained in channel 105 and there is certain spacing in the open end 103 apart from U-shaped structure body,
The present embodiment attached drawing is only in case where the end for pushing silk 400 is flushed with the open end 103 of U-shaped structure body.
Optionally, due to push silk 400 need pull so that fixator deform, in order to enable fixator deformation process more
Add stabilization, pushes the turnover between the part of silk 400 being contained in channel 105 and the part outside U-shaped structure ontology 100
Place corresponds at 1/2 length of U-shaped structure ontology 100, in this way, being pushed away after then making fixator be sent into tissue by pulling
Wire feed 400 so that fixator middle part stress, then fixator is whole generates Bending Deformation from middle part to both sides, that is, is distributed in
The arc end 101 of fixator on both sides of the middle and open end 103 are distributed the side deformation for facing away from push silk 400, that is, can avoid
Tissue is supported in arc end 101 and open end 103, reduces damage of the fixator for tissue.Certainly silk 400 is pushed
Turning point between the part being contained in channel 105 and the part outside U-shaped structure ontology 100 also corresponds to U-shaped knot
At the length of other situations of structure ontology 100, such as 1/3 length, as long as can be promoted admittedly by pushing the pulling function of silk 400
The requirement that device deformation is all satisfied the present embodiment is determined, in this regard, the present embodiment does not do absolute limit.
It please refers to shown in Fig. 2, optionally, push silk 400 is hard silk suture, has certain push intensity.And in hard
The surface of silk thread is coated with macromolecule material coating 402, and the setting of macromolecule material coating 402 can reduce friction when push
Power.
Also optional, push silk 400 is that soft silk suture matches other instruments herein with the mating push of other instruments
Set push belongs to conventional technical means, and this embodiment is not repeated.
The recyclable puncture anchor of the flexibility of the present embodiment is as follows with fixator specific embodiment:
It please refers to shown in Fig. 3 to Fig. 5, under the guidance of scope, scope puncture needle 1 (or other similar instrument) puncture group
It knits and reaches target position, then receiving the push silk 400 for puncturing anchor and fixator is a straight line, will be fixed using push silk 400
Device from the inner hole of puncture needle 1 is pushed out 1 head end of scope puncture needle, and (one end that fixator is not connected to exhausting line 300 is introduced into puncture
The inner hole of needle 1), subsequent fixator withdraws from scope puncture needle 1, pulls push silk 400 automatically with push silk 400 at plumbness,
Can be mobile by tissue retraction, reach the effect of closing up of tissue and tissue, in the process, fixator is with push silk 400
Drawing generates deformation.Destination organization can certainly be individually moved, the approach provided convenience to operative treatment.Operation is completed
Afterwards, pull exhausting line 300, fixator automatically with exhausting line 300 in line, to withdraw from puncture anchor.
