Shoulder joint sutures self-locking structureTechnical field
The present invention relates to a kind of self-locking structure, and in particular to a kind of self-locking structure sutured suitable for shoulder joint.
Background technology
At present, existing common shoulder joint suture operation is the form of artificial linear slit., can be in shoulder joint specifically in operationFixed holdfast, and suture is manually sutured in shoulder in the affixed suture in top of holdfast, then by various wire passing devicesThe tissue in joint and the fixation that knots.Clearly as artificial shoulder joint mirror was played, the reason program of line knotting operation was complicated, walkRapid cumbersome, learning curve is very long, therefore is unfavorable for the quality and efficiency of suture operation under the development and popularization of such operation, mirrorAlways one the problem of have much room for improvement.
The content of the invention
To overcome the defect present in prior art, a kind of shoulder joint suture self-locking structure is now provided, pass is enormously simplifyLine knotting step excessively cumbersome among mirror shoulder joint repairing operation is saved, so as to shorten operating time, procedure efficiency is improved.
Self-locking structure is sutured there is provided a kind of shoulder joint to achieve the above object, suture self-locking structure includes：
Holdfast, including fixing end and from lock end, fixing end is fixed on the supraspinous muscle stop of shoulder joint, is offered from lock endShuttling holes；
From clavicle fixing belt, including top, end and self-locking tooth, top is fixed in from lock end, many uniform cloth of lattice self-locking toothLocated at from clavicle fixing belt, end is connected to the tissue of shoulder joint, self-locking through the shoulder sleeve and shuttling holes of shoulder joint and punctureFixing band progressively locks in shuttling holes certainly by self-locking tooth.
The beneficial effect of shoulder joint of the present invention suture self-locking structure is,
By the way that the supraspinous muscle stop of shoulder joint is connected with the disposable self-locking of tissue from clavicle fixing belt around together in holdfast, fromAnd the step of simplify arthroscope shoulder joint repairing operation, improve procedure efficiency.
Preferably, there is the major diameter of thread on screw thread, thread segment progressively to be reduced from lock end to fixing end certainly on holdfast, and thenFixing end screws togather the supraspinous muscle stop for being fixed on shoulder joint.
Preferably, the inwall of shuttling holes has the reverse latch for adapting to self-locking tooth.
Preferably, it is in smooth spininess from the end of clavicle fixing belt.
Preferably, it is curved metal from the end of clavicle fixing belt.
Brief description of the drawings
Fig. 1 is the schematic perspective view that shoulder joint of the present invention sutures self-locking structure；
Fig. 2 is the first implementation view that shoulder joint of the present invention sutures self-locking structure；
Fig. 3 is to implement view corresponding to the second of Fig. 1；
Fig. 4 is to implement view corresponding to the 3rd of Fig. 1.
Embodiment
For the benefit of to the understanding of structure of the invention, illustrated below in conjunction with drawings and Examples.
Reference picture 1, is the schematic perspective view that shoulder joint of the present invention sutures self-locking structure.Reference picture 2, is shoulder joint of the present inventionSuture self-locking structure first implements view.Reference picture 3, to implement view corresponding to the second of Fig. 1.
With reference to shown in Fig. 1 to Fig. 3, self-locking structure is sutured the invention provides a kind of shoulder joint, shoulder joint includes shoulder jointSupraspinous muscle stop 1 and shoulder joint tissue 2, suture self-locking structure include：The holdfast 3 that titanium alloy makes, including fixing end30 and from lock end 32, fixing end 30 is fixed on the supraspinous muscle stop 1 of shoulder joint, and shuttling holes 34 are offered from lock end 32；It is about50cm, made of nylon material from clavicle fixing belt 4, including top 40, end 42 and self-locking tooth 44, top 40 be fixed in fromExtension is unfolded in lock end 32, end 42 (in figure from left to right) in the first direction, and many lattice self-locking teeth 44 are uniformly laid in self-locking and fixedOn band 4, bypassed from reverse () of clavicle fixing belt 4 in the first direction from lock end 32, and then end 42 along first in figure from right to leftDirection is connected to the tissue 2 of shoulder joint through the shoulder sleeve 5 and shuttling holes 34 of shoulder joint and puncture, passes through certainly from clavicle fixing belt 4Lock tooth 44 progressively locks in shuttling holes 34 certainly.
Specifically, there is the major diameter of thread on thread segment 36, thread segment 36 from above-mentioned from lock end 32 to fixing end on holdfast 330 progressively reduce, and fixing end 30 has the tip protruded out, and then fixing end 30 screws togather the supraspinous muscle stop 1 for being fixed on shoulder joint.It is in boss-shaped from lock end 32, is available for facilitating turn holdfast 3.The inwall of shuttling holes 34 has the reverse latch for adapting to self-locking tooth340.From the end 42 of clavicle fixing belt 4 for metal material and in smooth arc spininess, for the convenient group for being pierced into shoulder jointKnit 2.
Reference picture 4, to implement view corresponding to the 3rd of Fig. 1.As shown in figure 4, treating from the fix tightly of clavicle fixing belt 4Rearward, in the state of locking is kept, the end 42 of tissue 2 will be protruded from and cut.
Complete after above-mentioned implementation process, following characteristics of the present invention should be able to be embodied：
By the way that the supraspinous muscle stop of shoulder joint is connected with the disposable self-locking of tissue from clavicle fixing belt around together in holdfast, fromAnd the step of mistake line cumbersome in arthroscope shoulder joint repairing operation knots is simplified, improve procedure efficiency.
The present invention is described in detail above in association with accompanying drawing embodiment, those skilled in the art can be according to upperState it is bright the present invention is made many variations example.Thus, some of embodiment details should not constitute limitation of the invention, thisInvention regard the scope defined using appended claims as protection domain.
