It is shown in figure:
First suture 1；Second suture 2；First aperture 201；Second aperture 202；Third aperture 203；Thread preformed hole
204；First contraction flow region 21；Tractive unit 22；Second contraction flow region 23.
Specific embodiment
The utility model is described in detail combined with specific embodiments below.Following embodiment will be helpful to this field
Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made.
These are all within the protection scope of the present invention.
As shown in Figure 1, full suture holdfast provided by the utility model includes the first suture 1 and the second suture 2, the second suture
2 are socketed on the first suture 1.First suture 1, the second suture 2 are respectively by High molecular weight polyethylene UHWMPE, poly terephthalic acid
The yarn of glycol ester PET material is worked out, and the cross-sectional shape of the first suture 1 is circle；As shown in Fig. 2, the second suture 2
It is worked out by the yarn oblique line intersection of PET material, in order to contraction distortion.
Second suture 2 is mainly in turn connected to form by the first contraction flow region 21, tractive unit 22, the second contraction flow region 23, and first receives
Contracting portion 21, tractive unit 22, be respectively arranged on the second contraction flow region 23 first aperture 201, the second aperture 202, third aperture 203 this
Three deformations are oriented to aperture；The position of first aperture 201, the second aperture 202, third aperture 203 in 2 circumferential direction of the second suture
It sets identical；First aperture 201 is symmetrically distributed in the second aperture 202 along the two of 2 axial direction of the second suture with third aperture 203
Side.Tractive unit 22 is fixedly connected with the first suture 1, for example is sutured tractive unit 22 and the first suture 1 by suture；First
Contraction flow region 21, the second contraction flow region 23 can then generate the opposite sliding of axial direction between the first suture 1, in tractive unit 22
Under limitation, in sliding, own form will shrink deformation, i.e., length shortens for the first contraction flow region 21, the second contraction flow region 23,
Cross-sectional diameter becomes larger；First aperture 201, the second aperture 202, third aperture 203 setting so that the contraction of the second suture 2
Become to be more easier.Threading preformed hole 204 is additionally provided on tractive unit 22, threading preformed hole 204 is radial along tractive unit 22
Tractive unit 22 is run through in direction, and threading preformed hole 204, which can be used for wearing, connects additional suture.In preference, the deformation guiding
Aperture can also exist only in any of the first contraction flow region 21, tractive unit 22,23 these three components of the second contraction flow region or appoint
On two components, but it will lead to the final contraction distortion difficulty of the second suture 2 and increase.Preferably, the first aperture 201, second open
It the position of hole 202, third aperture 203 in 2 circumferential direction of the second suture can be with difference, the first aperture 201 and third aperture
203 may not be it is symmetrical, specifically depending on service condition.In preference, between tractive unit 22 and the first suture 1 also
It can be unfixed, be conducive to the further contraction distortion of the second suture 2, but will lead to the first suture 1 and the second suture 2 is whole
Opposite sliding between body, is unfavorable for final fixation.
The utility model additionally provides a kind of implanted mechanism, comprising wire-threading device and above-mentioned full suture holdfast, wherein crossing line
Device is made of elastic nitinol alloy wire and plastic handle, and additional suture can be passed through threading preformed hole 204 by wire-threading device.
Embodiment: the first suture 1 is the circular suture being woven by High molecular weight polyethylene UHWMPE yarn, length
For 1m；Second suture 2 is woven by polyethylene terephtalate yarn, is fixed on 1 center of the first suture, length
20-30mm.Second suture, 2 interposition is equipped with a threading preformed hole 204, the diameter 1mm in hole, which is volume
External suture line passes through hole.The hole of 1.4mm is drilled out in the place for needing suture to put forth effort.The additional seams line used will be needed to pass through
Threading apparatus passes through prebored hole.Behind the hole that full suture holdfast is thrown into 1.4mm with driver, when the complete immersed hole of the second suture 2
Afterwards, driver is taken out, slowly tenses the first suture 1 later until drawing is motionless, the second suture 2 is under pulling force trend, meeting
Contraction distortion is stuck in hole to fixed.After confirming that full suture anchor fixation is errorless, 1 exposed portion of the first suture is cut and is taken
Out, continue subsequent operation using additional seams line later.
Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims,
This has no effect on the substantive content of the utility model.In the absence of conflict, the spy in embodiments herein and embodiment
Sign can be arbitrarily combined with each other.
