All fronts holdfastTechnical field
The present invention relates to the field of medical instrument technology, in particular to a kind of all fronts holdfast.
Background technique
Overexertion or it is otherwise due to, the intracorporal ligament of people, tendon and/or other soft tissues from itsCompletely or partially being detached from for associated bone is relatively common damage, in order to help the part being detached from and bone as soon as possibleBone combines as soon as possible, needs to attach to damaged tissues on bone associated there again by way of operation.
Method of tissue repair common at present is to first pass through the anchoring pieces such as screw, staple, suture anchor and hobnail in phaseDrilling fixation is carried out on the bone answered, by the way that damaged tissues are fixed on bone with anchoring piece associated suture, thusGuarantee the quick reparation of damaged tissues.Due to carrying out drilling operation on bone, certain damage can be caused to bone, in order to the greatest extentThe possible injury for reducing drilling operation to bone, it should which the area of drilling is reduced to minimum.However, too small drilling can be ledIt causes the volume of anchoring piece to become smaller, and then influences the intensity of anchoring piece, simultaneously because anchoring piece will also cause to anchor by sutureThe volume of part can not be done too small.
Therefore, a kind of completely new holdfast is needed.

Specific embodiment
The embodiment of the present invention is described in detail with reference to the accompanying drawing.
It will be appreciated that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.BaseEmbodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all itsIts embodiment, shall fall within the protection scope of the present invention.
Referring to Fig. 1-2, the embodiment of the invention provides a kind of all fronts holdfasts, comprising:
First suture 1, first suture 1 have the first length；With first suture 1 disposed in parallelTwo sutures 2, second suture 2 have the second length；Shrink deformations 3, the contractions deformations 3 are with described theThe receiving portion that one suture 1 and second suture 2 combine, parallel with the first suture 1 and second suture 2Direction, it is described shrink deformations 3 have non-constricting state under third length and the 4th length under contraction state, the described 4thLength is less than the third length.
By the way that 2 sutures are arranged, can effectively impaired tissue be sutured and be bound, be sutured as neededThe difference of tissue, the first suture 1 and the second suture 2 can have different length, effective in order to carry out to tissueSuture.It shrinks deformations 3 and is in non-constricting state before the use, its length of run is third length at this time.When shape will be shunkAfter change portion 3 is entered in bone chamber by the bone that tool is placed into punching, user stretches the first suture 1 and the second suture 2,Since bone through-hole is sufficiently small, it can hinder shrinking deformations 3 and being formed, cause contraction deformations 3 to be shrunk to one, formed and receivedContracting state, the length of contraction deformations 3 is the 4th length by third length reduction at this time.After contraction deformations 3 are cuddled up in a heap, justIt is firmly fixed on bone, at this point it is possible to be sutured by the first suture 1 and the second suture 2 to impaired tissueAnd binding, so that damaged tissues be made to attach on corresponding bone.
A kind of specific implementation according to an embodiment of the present invention, described contraction deformations 3 is with the first weave diagramsThe cylindrical braid of case, the cylindrical braid have inner cavity, and the inner cavity forms receiving portion, first suture 1And second suture 2 is parallel through the inner cavity.
A kind of specific implementation according to an embodiment of the present invention, described contraction deformations 3 is with the second weave diagramsThe strip braided fabric of case, has multiple through-holes on the strip braided fabric, and the multiple through-hole forms receiving portion, and described theOne suture 1 and second suture 2 are parallel through the multiple through-hole.
Since the skeletal shape of human body different parts is different, according to the size and shape of practical bone, can chooseThe contraction deformations of cylindrical braid also can choose the contraction deformations with strip braided fabric.
First length of a kind of specific implementation according to an embodiment of the present invention, first suture 1 is greater than secondSecond length of suture 2 sutures damaged tissues in this way, user can choose the suture of different length.
A kind of specific implementation according to an embodiment of the present invention, the first suture 1 and the second suture 2 in addition to length notIt, can be with thickness difference with except.For example, first suture 1 has the first cross section, second suture 2 hasSecond cross section, first cross section are greater than second cross section, that is, 1 to the second suture 2 thick one of the first sutureA bit.In an all fronts holdfast, the suture of different thicknesses is set, it can be according to the size or stress intensity of damaged tissues notTogether, the suture of different thicknesses is selected to be sutured or bound.
Referring to Fig. 3-5, a kind of specific implementation according to an embodiment of the present invention, first suture 1 includes and instituteFirst part 11 and the second part used for suturing 12 of receiving portion combination are stated, it is different by the way that the first suture 1 to be arranged toPart is fixed on position corresponding to the first part 11 of the first suture 1 convenient for will effectively shrink deformations 3.
A kind of specific implementation according to an embodiment of the present invention, referring to Fig. 3, the first part 11 has third transversalFace, the second part 12 have the 4th cross section, and the third cross section is less than the 4th cross section.At this point, firstDivide 11 relatively slightly compared to second part 12, can preferably fix and shrink deformations 3.
A kind of specific implementation according to an embodiment of the present invention, referring to fig. 4, the first part 11 have verticallyBulge-structure 111, the bulge-structure 111 is for preventing the contraction deformations 3 from contraction state to non-constricting state shapeBecome, bulge-structure 111 can be fixed to above first part 11 in such a way that braided fabric weaves, and can also pass through other classesIt is formed like mode.
A kind of specific implementation according to an embodiment of the present invention, referring to Fig. 5, the first part 11 has different directionsBarb structure 112, the barb structure 112 is for preventing the contraction deformations from contraction state to non-constricting state shapeBecome.Barb structure 112 can be fixed to above first part 11 in such a way that braided fabric weaves, and can also pass through other classesIt is formed like mode.
First part 11 and second part are differentiated for the ease of user, it is according to an embodiment of the present invention a kind of specificImplementation, the first part 11 have the first pattern, the second part 12 have the second pattern, first pattern withSecond pattern is different.Specifically, the first pattern and the second pattern can pass through different colors, different establishment stripeds etc.Pattern is realized.
Other than the first suture 1 has above-mentioned setting, the second suture also can have similar setting.MeanwhileAccording to the actual needs, other than 2 sutures, more sutures can also be arranged in all fronts holdfast.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, anyIn the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by those familiar with the art, all answersIt is included within the scope of the present invention.Therefore, protection scope of the present invention should be subject to the protection scope in claims.
