The specific embodiment
This utility model has disclosed a kind of assistive device of tubular binding strument, especially a kind ofly enters guiding piece in body for the guiding tubular binding strument, concrete embodiment as shown in the figure.
The tubular binding strument of prior art, as shown in Figure 5, comprise pipe 7, be located at the nail-anvil assembly, nail bin groupware of described pipe 7 far-ends and be used for holding the nail barrel of nail bin groupware, and the anvil pull rod 9 that is arranged on movably in described nail barrel and is used for being connected with described nail-anvil assembly.Described nail bin groupware comprises nail bin 3 and the anastomosis staple that is placed in nail bin, and is arranged on movably cutting knife 11 and the pushing slice of nail of nail barrel 1 inside, and the far-end of described nail bin 3 is the nail bin face, and is relative with the nail anvil face of nail-anvil assembly.Described cutting knife 11 is close to the nail bin inwall 5 of described nail bin 3.
In this utility model, as shown in Figures 1 to 4, described guiding piece is the truncated cone-shaped of hollow, comprises a near-end 17 and a far-end 15, and the outer wall 13 that connects this near-end 17 and far-end 15, and described far-end 15 increases gradually to the external diameter of near-end 17.Characteristics of the present utility model are: described guiding piece fixedly is spliced by splicing construction by one group of splicing block 27, and all splicing blocks 27 connect by same traction piece 23 and connect.Described traction piece 23 is a drag wire, can establish circular hole 33 on described splicing block 27, described traction piece 23 passes the circular hole 33 of all splicing blocks 27, one end of traction piece 23 is fixed on the splicing block 27 of distal-most end, the free end of its other end for being pulled, after guiding piece consisted of integrative-structure, traction piece 23 was tightened up for the splicing between each contiguous concatenation piece 27 on further fixed guide.
Concrete, described guiding piece is spliced by the splicing block circle 271,272 of two circles at least, and described splicing block circle 271,272 is formed by described splicing block 27 close-packed arrays.Described splicing construction is the projection that cooperatively interacts 29 and the groove 31 that is separately positioned on adjacent splicing block circle 271,272.Like this, adjacent splicing block circle 271,272 just can interfix.This preferred embodiment comprises 4 splicing block circles.Certainly, also can adopt splicing construction to interfix between the splicing block 27 on same splicing block circle, this splicing construction can be the projection that cooperatively interacts 29 and the groove 31 that is separately positioned on adjacent splicing block 27.Only for giving an example, the description in being not limited to illustrate can also be the spheroid that protrudes and the recessed spheroid that matches etc. to splicing construction in this utility model.
Described splicing block circle 271,272 outer wall form the outer wall 13 of described guiding piece, and adjacent described splicing block circle 271,272 outer wall seamlessly transit, and like this, this outer wall 13 can not scraped injured tissue when guiding tubular binding strument and enter in the patient body.
Except the aforesaid circular hole 33 of establishing on splicing block 27, described traction piece 23 passes outside the circular hole 33 of all splicing blocks 27, the equal injection moulding of all splicing blocks 27 can also be fixed on described drag wire.As long as described traction piece 23 plays draw.Described tubular binding strument nail barrel is provided with at least one bullport, and the other end of described traction piece 23 passes from described bullport when original state.
The near-end 17 of described guiding piece also is outward extended with an Access Division 25, and the external diameter of described Access Division 25 is less than or equal to the internal diameter of the nail bin inwall 5 of described nail bin 3.Guiding piece can be connected on nail bin 3 like this.The maximum outside diameter of described guiding piece is less than or equal to the external diameter of nail barrel 1, and like this, guiding piece can not increase the nail barrel entire outer diameter, reduces the difficulty that tubular binding strument enters tissue.
When operation, first the guiding piece of this preferred embodiment is socketed in the far-end of nail bin groupware, then guide tubular binding strument to enter in human body, the free end of traction piece 23 passed bullport and was exposed to outside the patient body this moment.Then pull described traction piece 23, described guiding piece is disintegrated by the order that draws near, final formation can break away from a string splicing block string that is connected by described traction piece 23 of tubular binding strument.Certainly the above embodiments also can be extracted out from the Binding Instrument outside, as long as the change traction piece is positioned at the link position on guiding piece.
Of the present utility model simple to operate, only need can realize that once going on foot guiding piece breaks away from described tubular binding strument.
This utility model still has multiple concrete embodiment, is equal to replacement or equivalent transformation and all technical schemes of forming, within all dropping on the claimed scope of this utility model.
