Detailed description of the invention
Below in conjunction with each embodiment shown in the drawings, the present invention is described in detail; but should be noted that; these embodiments are not limitation of the present invention; those of ordinary skill in the art are according to these embodiment institute work energy, method or structural equivalent transformations or substitute, and all belong within protection scope of the present invention.
Shown in please refer to the drawing 1, what Fig. 1 showed is a kind of tubular binding strument 100 that guiding device is not housed.Described tubular binding strument 100 comprises nail barrel 11, be installed on nail bin 12 in nail barrel 11 and anvil pull rod 13, be installed in described nail barrel 11 and annular cutting knife 14 between described nail bin 12 and anvil pull rod 13.Described tubular binding strument 100 and tubular binding strument similar of the prior art, do not go to live in the household of one's in-laws on getting married herein.
Shown in please refer to the drawing 2, Fig. 2 discloses a kind of guiding device 200 in embodiment of the present invention.Described guiding device 200 is removably installed in described nail barrel 11, guides described tubular binding strument 100 enter human body and can not damage the effect of tissue to play.From structure, described guiding device 200 comprises guide part 2 and the location division 3 of whole installation, and namely described guide part 2 forms as one with location division 3.Described location division 3 is in order to support described guide part 2.During installation, described location division 3 is in order to be inserted in described nail barrel 11, and described guide part 2 protrudes from described nail barrel 11.
Described guide part 2 is provided with the first outer surface 21 that is smooth, that can play import feature, the first cavity 22 of hollow and the first inner surface 23 of being exposed in described first cavity 22.The outline of described guide part 2 is distally contraction-like from near-end.Described first outer surface 21 is level and smooth taper shape or circular arc, thus is convenient to guide described tubular binding strument 100 enter human body and can not damage tissue.In addition, described first outer surface 21 is that complete being beneficial to provides enough intensity, is unlikely to cave in importing process.Preferably, the not obvious maximum outside diameter exceeding described nail barrel 11 of the maximum outside diameter of described guide part 2, even if so also obviously can not increase the external diameter of tubular binding strument 100 when described guide part 2 is contained on described tubular binding strument 100, thus the misery of patient can not be increased while tubular binding strument 100 inserts human body.
Described first inner surface 23 is provided with spiral helicine first groove 231, the depths of described first groove 231 near described first outer surface 21, thus make the wall thickness of guide part 2 become very thin.In fact described first groove 231 is exactly for tearing the tear trace that described guide part 2 provides.Described guide part 2 can be pulled and disintegrate in the shape of a spiral gradually along the first groove 231, so that take out described guide part 2.
In addition, described guide part 2 is provided with the bump structure 24 being positioned at described near-end, and described bump structure 24 (is such as arranged at the hole on nail bin 12) in order to be installed in hole corresponding to described tubular binding strument.
Described location division 3 is connected in described first cavity 22.Described location division 3 is provided with the second outer surface 31, the second cavity 32 of hollow and the second inner surface 33 of being exposed in described second cavity 32.Described second outer surface 31 is for cylindrical shape is so that be inserted in described nail barrel 11.In addition, described second outer surface 31 is that complete being beneficial to provides enough intensity.Described location division 3 protrudes from described guide part 2 from described near-end, and described location division 3 extends beyond described bump structure 24.
Described second inner surface 33 is provided with spiral helicine some second grooves 331, the depths of described second groove 331 near described second outer surface 31, thus make the wall thickness of location division 3 become very thin.In fact described second groove 331 is exactly that described location division 3 can be pulled and disintegrate in the shape of a spiral gradually along described second groove 331, so that take out described location division 3 in order to tear the tear trace that described location division 3 provides.
Preferably, described guide part 2 is provided with the traction piece 25 being positioned at its top, and described traction piece 25 is drawn by described near-end through the first cavity 22 and the second cavity 32, described guide part 2 and location division 3 described traction piece 25 dilatory under disintegrate in the shape of a spiral.In addition, described tubular binding strument 100 is provided with the bullport (not shown) that at least one is exposed to outside, passes for described traction piece 25.When guiding device 200 is arranged in described nail barrel 11, after described tubular binding strument 100 is imported tissue, the end of described traction piece 25 is positioned at outside tissue so that operation.
Described spiral first groove 231 has identical pitch with the second groove 331, i.e. G1=G2.Described spiral first groove 231 has the identical hand of spiral with the second groove 331.Described guiding device 200 is provided with the connecting portion 26 being positioned at described guide part 2 and junction, location division 3, disintegrates in described guide part 2 and location division 3 under the traction of described traction piece 25 from this connecting portion 26 simultaneously.
During use, first the guiding device 200 of this preferred embodiment is socketed in the far-end (position near anvil pull rod 13) of tubular binding strument 100, then enter in human body by guiding tubular binding strument 100, now the end of traction piece 25 exposes for outside human body through after bullport.After guiding tubular binding strument 100 arrives precalculated position, by pullling outside traction piece 25 thus making described guide part 2 first disintegrate; When described guide part 2 disintegrates the position arriving described connecting portion 26, disintegrate subsequently in described guide part 2 and location division 3 from this connecting portion 26 simultaneously, not only easy to operate, and can extract described guiding device 200 fast out.Finally, described guiding device 200 is formed as strip body and is drawn out of outside tubular binding strument 100 from described bullport once.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or basic feature, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
