The specific embodiment
Refer to shown in Fig. 1-7, invention high strength can absorb suturing nail, comprises that employing can absorb rivet nut 1 and the securing member 2 of material.Wherein, rivet nut 1 comprises base 11 and is fixed on the nail body 12 more than two on same base 11, and along the axis direction of each nail body 12, the installing hole 13 that connects rivet nut is set.Securing member 2 is provided with the hole clipping 21 corresponding with following closely body 12 quantity, position, and by this hole clipping 21 and rivet nut 1 top clamping.
Preferably, nail body 12 can adopt column structure as shown in the figure, also can adopt conical structure to penetrate being more conducive to.The ailhead of rivet nut 1 be take taper shape as best, and conical bottom surface slightly larger in diameter is in the diameter of nail body 12 and securing member hole clipping 21, thereby forms card convex 14.In addition, as shown in Figure 5,14, two card convexs 14 of a card convex can be set more below ailhead card convex 14 again and form clamping with the above and below of securing member 2 respectively, syndeton is more firm, stable.
In order to adapt to the requirement reached applicable to various anastomats flexible for installation, the preferred U-shaped pin structure of this utility model suturing nail, be fixed with two nail bodies 12 on same base 11, securing member 2 can adopt the slab construction with two circular holes, the shape of nail body base 11 and securing member 2 is with identical or correspond to suitable, usually can adopt the rectangle with chamfering as Figure 1-5 with for Linear cutting suturing device, also can adopt crescent as shown in Figure 6,7 to be applicable to tube type anastomat.
Refer to shown in Fig. 8-21, nail bin groupware of the present invention comprises that ejector pin piece 3, nail supporting base 4, nail bin 5 and high strength of the present invention can absorb suturing nail.
Wherein, ejector pin piece 3 comprises body 31 and is fixed on the booster injection 32 on body, and the setting position of booster injection 32 is corresponding with suturing nail rivet nut 1 position and insert in the installing hole 13 of rivet nut.Ejector pin piece 3, with suturing nail rivet nut base 11 and securing member 2 shapes are identical or corresponding being advisable, for example adopts the rectangle with chamfering as shown in Fig. 8-11, or adopts the crescent as shown in Figure 16-18.In addition, ejector pin piece 3 both can be made as single structure as shown in Figure 8, also can be made as the integrative-structure as shown in Fig. 9, Figure 11.Booster injection 32 adopts metal material usually, and its length is slightly larger than the length of suturing nail rivet nut installing hole 13.Because nail body 11 is hollow-core construction, the end of metal booster injection 32 stretches out the suturing nail ailhead, when suture tissue, and the effect of can play strength-enhanced, passing smoothly tissue.
The ejector pin piece 3 that is fixed with suturing nail rivet nut 1 can slide up and down and is arranged in nail bin 5.Below nail bin 5 installing holes, be for example a cavity structure, be used for installing ejector pin piece 3, the inner surface structure of nail bin 5 cavitys and the surface texture of ejector pin piece 3 match, and enable to slide up and down in nail bin 5.
The securing member 2 of suturing nail is arranged on nail supporting base 4.As shown in Figure 12-14, cylindrical bump 41 can be set on nail supporting base 4, this projection 41 and nail supporting base 4 flexible fastenings, its setting position is corresponding with the position of securing member hole clipping 21, and diameter is equal to or slightly less than the internal diameter of securing member hole clipping 21.In addition, also can on nail supporting base 4 upper protruding block 41 correspondence positions, circular trough 42 be set, projection 41 is fixed in circular trough 42 by four elastic supporting beams 43 structural elasticities as shown in figure 13.
High strength of the present invention can absorb suturing nail and nail bin groupware thereof, both can be applicable to the Linear cutting suturing device shown in Figure 15, also can be applicable to the tube type anastomat shown in Figure 21, so that being installed in nail bin, two row's ejector pin pieces and suturing nail be advisable, and two row's suturing nails are staggered, and the projection on nail supporting base also respective quadrature replaces spread configuration.
During installation, at first by suturing nail, follow closely body installing hole 13, suturing nail rivet nut 1 is inserted on the booster injection 32 of ejector pin piece 3, be fixed, then whole fixed structure is arranged in nail bin 5, then securing member 2 is arranged on nail supporting base 4, and fix by hole clipping 21 buckles of projection 41 and securing member 2.
During suture tissue, ejector pin piece 3 is tried hard to recommend outside under moving and is moved up with nail bin groupware, and suturing nail rivet nut 1 is slided forward together under the drive of ejector pin piece, and skids off nail bin 5, and nail body 11 is through tissue.The conical ailhead of simultaneously following closely body 11 arrives in the hole clipping 21 of securing member 2, and under the effect of thrust, ailhead acts on the cylindrical bump 41 that is positioned at hole clipping 21, makes securing member 2 break away from projection 41 and nail supporting base 4.When conical ailhead passes completely through securing member 2, form interference fit, connect and fix, rivet nut 1 and securing member 2 tight closure form " mouth " word structure.After stitching completes, apparatus resets, and metal booster injection 32 exits suturing nail nail body installing hole 13 with ejector pin piece 3, and turns back in nail bin 5, and suturing nail breaks away from apparatus with tissue, remains in human body.
The above; it is only preferred embodiment of the present invention; not the present invention is done to any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection scope of the present invention.
