The specific embodiment
The present invention has disclosed a kind of assistive device of tubular binding strument, especially a kind ofly enters guide appendages in the body for the guiding tubular binding strument.
The tubular binding strument of prior art comprises nail-anvil assembly, nail bin groupware, is fixed in the pipe of described nail bin groupware near-end; Described nail bin groupware comprises nail barrel 1 and the nail bin 2 that interfixes, and the near-end of described nail barrel 1 is provided with at least one line hole 3.
Among the first embodiment as shown in Figures 1 to 4, described guide appendages comprises: for the sleeved part 4 of the far-end that is sheathed on described tubular binding strument, be located at the guide portion 6 of described sleeved part 4 far-ends, and the chimb 5 that is used for gripping of outwards dispersing setting of being located at described sleeved part 4 near-ends.
Described sleeved part 4 is cylindrical shape, and its internal diameter is greater than the external diameter of described nail barrel, and whole like this guide appendages can be set in the outside of nail barrel at an easy rate.
The outline of described guide portion 6 is a taper shape, and described conical inner chamber is the hollow setting.The maximum outside diameter of described guide portion 6 equals the minimum outer diameter of described sleeved part, and described guide portion 6 is helical member, and an end of the threaded line 61 of described helical member is connected with a traction piece 7, and the other end is connected with described sleeved part 4.All vertically be provided with one group of reinforcement 62 between the adjacent threaded line 61 of described helical member, being connected between described guide portion 6 and the sleeved part 4 also is to rely on this reinforcement 62.Described reinforcement 62 is the narrow and little plastic parts of an end, is similar to beverage bottle cap, is easy to be torn.After the reinforcement 62 between guide portion 6 and the sleeved part 4 is torn, just lose between described guide portion 6 and the sleeved part 4 and be connected, mutually break away from.
In this example, an end of described traction piece 7 is connected in the distal-most end center of threaded line 61.Described traction piece 7 passes from the line hole 3 of described nail barrel, and the other end of described traction piece 7 is provided with a draw ring 8.
The first embodiment is enclosed within guide appendages first the outside of nail bin groupware in when operation, enters surgery location in the human body by its conical structure guiding tubular binding strument; Then pull traction piece by draw ring, make the helix 61 that is connected in traction piece stressed and pull apart reinforcement 62, the helix 61 of whole like this guide portion is strip and is drawn out of outside tubular binding strument from line hole 3 once.Then, hand-held chimb 5 will be enclosed within the outer sleeved part 4 of nail barrel and draw to the near-end of tubular binding strument, and it is withdrawed from human body.Like this, tubular binding strument can be performed the operation.
Fig. 5, Fig. 6 have disclosed the second embodiment of the present invention, and its sleeved part is semi-cylindrical shaped.Characteristics maximum in this example are: described helical member is the threaded line 61 that two intervals center on, and is similar to existing mosquito incense.One end of these two threaded line 61 interconnects, and the other end all is connected by reinforcement 62 with described sleeved part.Described traction piece 7 is hooked on the end that links together of described two threaded line.
The second embodiment is enclosed within guide appendages first the outside of nail bin groupware in when operation, enters surgery location in the human body by its conical structure guiding tubular binding strument; Then pull traction piece, the link of two threaded line is stressed and pull apart reinforcement 62, and the helix 61 of whole like this guide portion is strip and is drawn out of outside tubular binding strument from line hole 3 once.Because two helixes 61 are out of shape simultaneously and pull out outside tubular binding strument, so its operating time is fast than the first embodiment.Then, hand-held chimb 5 will be enclosed within the outer sleeved part 4 of nail barrel and withdraw from human body to the near-end pulling of tubular binding strument.Like this, tubular binding strument can be performed the operation.
Fig. 7 to Fig. 9 has disclosed the third embodiment of the present invention.The characteristics of this embodiment are: described guide portion 6 is the flexible U-shaped convolution part that an integral molded plastic forms, the center cross-sectional of described U-shaped convolution part is U-shaped, described guide portion 6 comprises a near-end 17 and a far-end 15, the external diameter of described far-end 15 is less than the external diameter to near-end 17, and the external diameter of described near-end 17 equals the external diameter of nail bin 3 or nail barrel 1.The maximum difference of this example and previous embodiment be guide portion " helix " around shape.
Therefore show, the shape of " helix " of guide appendages of the present invention is not emphasis, helical form, U-shaped convolution shape except the present invention's announcement, it can also be other shape, so long as getting final product of enclosing of complete plastic strip, namely the U-shaped convolution shape plastic parts of the 3rd embodiment also can be used for the first embodiment.
In this example, the near-end 17 of described guide portion is a plane 25 of fitting with the nail bin face, and sleeved part 4 is for being sheathed on the thin-walled of described nail bin periphery, and described thin-walled and guide portion 6 are the flexible U-shaped convolution part that an integral molded plastic forms.Described thin-walled is provided with the clip 39 that is fixed on the nail bin.
Because operational approach and the first embodiment are roughly the same, therefore do not repeat them here.
Figure 10 and Figure 11 have disclosed the fourth embodiment of the present invention.Present embodiment and the first embodiment are similar, and described guide portion 6 is an integral loop around the flexible plastic parts of the spiral type that forms, namely this guide portion 6 be by a flexible plastic parts integral loop around the spiral type object that surrounds, be similar to spring.Described guide portion 6 is one section " spring wire ".
In the present embodiment, the bottom of the far-end 15 of the hollow cavity of described guide portion 6 inwardly convexes with a central tube 21, and the internal diameter of described central tube 21 equals the far-end external diameter of described anvil pull rod.When original state, described guide appendages can be set on the anvil pull rod by central tube 21 like this, and described guide appendages is coupled on the described tubular binding strument.
Offer a towing pad 23 on the proximal end wall of described central tube 21, the near-end of described central tube is an end of whole flexible plastic parts, is an end of " spring wire ".
The near-end of described guide portion 6 is a plane 25 of fitting with nail bin face 5.Sleeved part 4 is for being sheathed on the thin-walled of described nail bin periphery, and described thin-walled and guide portion 6 are the flexible plastic parts of spiral type that an integral molded plastic forms.
This embodiment is when operation, first guide appendages is socketed in the far-end of nail bin groupware, then guide tubular binding strument to enter in the human body, then pull the draught line that is connected in towing pad, make described guide appendages integral body be strip and be drawn out of once in tubular binding strument, be similar to " spring wire " drawn in line.
The guide portion of the above embodiments all can be extracted guide out from Binding Instrument inside, and namely the tubular binding strument nail barrel is provided with at least 1 bullport, and the described guide portion that is shoestring breaks away from described tubular binding strument from described bullport.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 the guide.
The present invention still has multiple concrete embodiment, is equal to replacement or equivalent transformation and all technical schemes of forming, all drops within the scope of protection of present invention.
