Technical field
This utility model relates to a kind of surgical attachment of tubular type binding appearance, relates in particular to a kind of guiding piece of tubular type binding appearance.
Background technology
The tubular type binding appearance is a kind of surgical instruments that tubular type is organized the seaming and cutting operation that is widely used in, and is made up of the nail-head component and the percussion assembly of circle; The tubular type tissue that two sections needs are coupled together is placed between the nail anvil and nail bin of nail-head component, and the distance of adjustment nail anvil and nail bin is come grip tissue gradually, and operation percussion assembly is shaped nail then, accomplishes the connection of two sections tissues.
In the operation technique of reality, there is the tubular type binding appearance of two kinds of operations to get into relatively difficulty of pipeline, be respectively low rectal operation and gastric bypass operation.The operation of first kind of low rectal, employing be that diameter is 33 millimeters a tubular type binding appearance, need per anum to undergo surgery because anus is a flesh property opening, its diameter of normal condition is less, and 33 millimeters apparatuses are inserted into relatively difficulty of anus.Second kind of gastric bypass operation; What adopt is that diameter is 25 millimeters a tubular type binding appearance, needs to get into small intestinal and undergos surgery, and small intestinal is the digester tube of human body; Inwall has a lot of mucosas; And the tubular type binding appearance is because end face is bigger, and because the reasons in structure surface is not sufficiently oily, in small intestinal, walks and be prone to mucosa is caused damage.
A kind of assistive device that is set in tubular type binding appearance nail bin groupware periphery that the prior art that addresses the above problem at present discloses for U.S. Patent application US2009020410; Nail bin groupware that can the tubular Binding Instrument of aimming circle gets into human body and passes intestinal; And after it arrives the operation precalculated position, can lay down this assistive device from nail bin groupware, do not influence the subsequent operation of tubular type binding appearance.This assistive device can help the doctor that nail bin groupware is successfully put into preposition, but this assistive device is relatively more expensive at present, can't be offered Chinese market widely.
The utility model content
The purpose of this utility model is to solve above-mentioned technical problem, and a kind of simple in structure, easy to operate guiding piece is provided.
The purpose of this utility model realizes through following technical scheme:
A kind of guiding piece is coupled on the tubular type binding appearance, and said tubular type binding appearance comprises nail-anvil assembly and the nail bin groupware that is oppositely arranged; Said nail bin groupware comprises nail tube and the nail bin that interfixes,
Said guiding piece comprises the sleeved part in the nail bin groupware outside that is used to be sheathed on said tubular type binding appearance, and the guide portion of being located at said sleeved part far-end;
The said guide portion and the sleeved part outside seamlessly transit, and inside is hollow structure;
The outside of said guide portion is big round table-like of the little near-end of far-end;
The wall of said guide portion is provided with the tear tape that the said guide portion at least one edge axially is provided with, and during original state, said tear tape and guide portion are a complete integral body; After said tear tape was stressed, the axial separation of the said guide portion in said tear tape edge also made said guide portion form the size breach suitable with said tear tape;
One end of said tear tape is the force side, fixes with a stay cord.
Preferably, during original state, between all the other positions of said tear tape and guide portion dowel is arranged.
Preferably, the proximal extension of said tear tape to said sleeved part.
Preferably, said guiding piece is provided with four symmetric in twos tear tapes.
Preferably, the two ends of said stay cord are fixed with the force side of two adjacent tear tapes respectively.
Preferably, the stiff end of said stay cord and the force side of tear tape are fixed, and the movable end of said stay cord passes the outside that the lacing hole of being located at said guiding piece near-end is placed on said guiding piece.
Preferably, the inwall of said guiding piece is provided with four ring platforms, and said stay cord passes the ring platform.
The beneficial effect of this utility model is mainly reflected in: under the effect of stay cord, tear tape is stripped from said guide portion, and the far-end of said guide portion can outwards be opened, and the guiding piece of having accomplished guiding function is withdrawed from from the periphery of tubular type binding appearance at an easy rate.And, when guiding,, therefore have enough intensity again because guide portion is a complete position, can realize guiding function well.

The specific embodiment
This utility model has disclosed a kind of assistive device of tubular type binding appearance, and especially a kind of aimming circle cast Binding Instrument that is used for gets into intravital guiding piece.The tubular type binding appearance of prior art comprises nail-anvil assembly, the nail bin groupware that is oppositely arranged, and the pipe that is fixed in said nail bin groupware near-end; Said nail bin groupware comprises nail tube and the nail bin that interfixes.
To first embodiment shown in Figure 4, said guiding piece comprises like Fig. 1: be used to be sheathed on the sleeved part 1 in the nail bin groupware outside of said tubular type binding appearance, and the guide portion 2 of being located at said sleeved part 1 far-end 10.
Said sleeved part 1 is a cylindrical shape, and its internal diameter is greater than the external diameter of said nail tube, and whole like this guiding piece can be set in the outside of nail tube at an easy rate.
Said guide portion 2 seamlessly transits with sleeved part 1 outside, and inside is hollow structure; The outside of said guide portion 2 is big round table-like of the little near-end of far-end; The wall of said guide portion 2 is provided with the tear tape 3 that the said guide portion at least one edge axially is provided with.Certainly, the near-end of said tear tape 3 may extend to said sleeved part 1, and promptly this tear tape 3 can only be located at said guide portion 2, also can wherein have long part to extend to sleeved part 1.Between all the other positions of said tear tape 3 and guide portion 2 dowel is arranged.Said dowel is a narrow and little plastic parts, is similar to beverage bottle cap, is easy to be torn.During original state, said tear tape 3 is the part of complete guide portion 2; After said tear tape 3 was stressed, said tear tape 3 was along the axial separation of said guide portion 2 and make said guide portion 2 form the suitable breach of a size and said tear tape 3.
In this preferred embodiment, said guiding piece is provided with four symmetric in twos tear tapes 3.The far-end of each tear tape 3 is the force side, fixes with a stay cord 4.The two ends of said stay cord 4 are fixed with the force side of two adjacent tear tapes 3 respectively, form the stiff end 41 of stay cord, and the movable end 42 of said stay cord 4 passes the outside that the lacing hole 7 of being located at said guiding piece near-end is placed on said guiding piece near-end 20.Promptly two of a complete stay cord 4 ends are the fixing stiff end 41 of tear tape, and the middle part of stay cord 4 is the movable end of this utility model.
