Abstract
The utility model discloses a kind of fixed holdfasts, characterized in that the cylinder including bullet type coaxially the heart and is integrally formed and is provided with round table-like anticreep hangnail on cylinder；Or setting screw thread item is integrally formed to cylinder upper end and cylinder upwards from cylinder lower end spiral；The lower end setting threading head of cylinder.The utility model can increase holding power of the holdfast in cancellous bone, prevent holdfast from deviating from, avoid because holdfast deviates from bring second operation, advantageously reduce patient medical cost by the way that anticreep hangnail or screw thread item are arranged on holdfast cylinder.
Description
Technical field
The utility model relates to medical instruments field, in particular to a kind of fixation holdfast.
Background technique
It is frequently necessary to repair damage by surgical operation when rotator cuff or other tendon injuries and promotes rehabilitation；Bone and tendon
Between fixation usually require holdfast spline structure to realize.The surgical operation of rotator cuff injury is repaired generally with two rows of holdfasts: first
Rotator cuff is passed through in the inner part as far as possible with the line on interior row's holdfast, resets rotator cuff；It again will be on interior row's holdfast with outlet holdfast
Suture is pushed together with rotator cuff, can sufficiently increase the contact area of rotator cuff and greater tubercles of humerus in this way.In the design of holdfast, compare
It is important that increasing holding power of the holdfast in cancellous bone, to greatest extent to draw in the suture of connection relative to holdfast
The risk that holdfast is extracted from cancellous bone is reduced when tight to greatest extent.Many ways are to increase holdfast size, but holdfast hand thus
Art is arthroscopic surgery, and holdfast larger will lead to the destruction increased to cancellous bone.
Utility model content
The purpose of the utility model is to provide a kind of fixed holdfast, there is the holding power in human body cancellous bone preferably to imitate
Fruit.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of fixed holdfast, characterized in that cylinder, and integrated molding concentric with the cylinder including bullet type are set
Set multiple round table-like anticreep hangnails on cylinder；The diameter of smaller one end of the anticreep hangnail be equal to cylinder diameter and this
It holds towards the top of cylinder.
A kind of fixed holdfast, characterized in that including bullet type cylinder, from cylinder lower end spiral upwards on cylinder
End is integrally formed the screw thread item of setting with cylinder.
The utility model is further arranged to: bone uptake hole is distributed with around axis on the cylinder.
The utility model is further arranged to: being mutually perpendicular between the two neighboring bone uptake hole.
The utility model is further arranged to: the tail portion of the cylinder is provided with line end, sets through line end two sides
It is equipped with cable-through hole.
In conclusion the utility model has the following beneficial effects:
One, holdfast cylinder be made into bullet type, enter cancellous bone convenient for holdfast, the anticreep hangnail of setting can increase anchor
The holding power in cancellous bone is followed closely, prevents holdfast from deviating from, avoids because holdfast deviates from bring second operation, advantageously reduces trouble
Person's medical treatment cost；
Secondly, the bone uptake hole that is distributed on cylinder, can guarantee that cancellous bone cancellous bone can grow to the inside in agglutination,
Conducive to the growth of bone, the holding power of holdfast is further enhanced, reduces the possibility for causing holdfast to fall off for some reason in life.
Thirdly, cable-through hole free adjusting can be carried out before knotting to suture after holdfast is fixed on cancellous bone bone hole, increase
The controllability for having added operation, can effectively increase surgical effect.

Fig. 2 is the structural schematic diagram of the utility model another embodiment；
Fig. 3 is the top view of Fig. 1；
Fig. 4 is the top view of Fig. 2.
In figure: 1, cylinder；2, anticreep hangnail；3, bone uptake hole；4, line end；5, cable-through hole；6, screw thread item.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Specific embodiment is only the explanation to the utility model, is not limitations of the present invention, this field
Technical staff can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but only
It will be in the scope of the claims of the utility model all by the protection of Patent Law.
Embodiment one, a kind of fixed holdfast, as shown in attached drawing 1, attached drawing 3, cylinder 1 and cylinder 1 including bullet type are same
The round table-like anticreep hangnail 2 that axle center and integrated molding are arranged on cylinder 1；The diameter of smaller one end of anticreep hangnail 2 is equal to column
The diameter of body 1 and this end are towards the top of cylinder 1；Bone uptake hole 3, two neighboring bone uptake hole 3 is distributed with around axis on cylinder 1
Between be mutually perpendicular to, the tail portion of cylinder 1 is provided with line end 4, and 4 two sides of line end are provided with cable-through hole 5.Holdfast is using
When cancellous bone is placed in by way of hammering.
Embodiment two, a kind of fixed holdfast, as shown in attached drawing 2, attached drawing 4, including bullet type cylinder 1, from 1 lower end of cylinder
Spiral arrives the screw thread item 6 that 1 upper end of cylinder and cylinder 1 are integrally formed setting upwards, and bone uptake hole 3 is distributed with around axis on cylinder 1,
It is mutually perpendicular between two neighboring bone uptake hole 3, the tail portion of cylinder 1 is provided with line end 4, is provided with through 4 two sides of line end
Cable-through hole 5.Holdfast is implanted into cancellous bone by way of being screwed into when in use.
