Description
Technical field
This utility model relates to a kind of stopper far-end induction system, for the conveying of stopper in sheath pipe.
Background technology
The conveyer device that stopper product uses mainly is threaded connection with push rod far-end by stopper far-end steel bushing or buckle is connected.Mainly there is following problem:
1, when stopper is by sheath pipe, stress point concentrates on shutoff far-end steel bushing, when stopper meets obstructions or bend pathological changes, far-end steel bushing can deflect, and rubs with delivery sheath tube wall, causes propelling movement power cannot be delivered to stopper smoothly, stopper is caused to push difficulty, as shown in Figure 1.If strengthen stopper silk material intensity, then cause the frictional force of stopper and sheath pipe to increase, thus cause stopper carrying capacity to rise.
2, stopper uses when being threaded, and after stopper overturns, push rod and stopper can be caused to be threaded tight fit, cause the difficulty increasing discharging stopper.
3, when after the release of stopper far-end card, stopper is formed horn-like by umbrella shape, then stopper income sheath pipe difficulty, causes great injury to operation and patient.
Summary of the invention
It is simple that the purpose of this utility model is to provide structure, has the stopper of better propelling movement property.
In order to achieve the above object, the technical solution of the utility model there is provided a kind of stopper far-end induction system, this stopper comprises far-end steel bushing and near-end steel bushing, it is characterized in that: described induction system comprises inner core silk assembly, surrounding layer assembly and distal handle assembly, wherein:
Inner core silk assembly comprises for the connecting portion one removably connected with the far-end steel bushing of stopper and the stiff wire be connected with connecting portion;
Surrounding layer assembly comprises the connecting portion two for removably connecting with the near-end steel bushing of stopper, and connecting portion two is fixedly connected with described distal handle assembly, and described wire rod freely passes through in surrounding layer assembly;
Distal handle assembly comprises handle and is located at the control device on handle, is controlled the length of described wire rod by this control device.
Preferably, described connecting portion one comprises with externally threaded inner core silk termination, and this inner core silk termination is provided with buckle one.
Preferably, described stiff wire or be nitinol alloy wire, medical stainless steel silk, multiply nitinol alloy wire composition stainless steel cable, or be multiply medical stainless steel silk form stainless steel cable.
Preferably, described connecting portion two, for being threaded and/or the termination of buckle two, has in the middle part of termination for the freely through passage of described stiff wire.
Preferably, described surrounding layer assembly also comprises tubing, and described connecting portion two is located at the end of tubing, and tubing is fixedly connected with described handle.
This utility model solves stopper produced problem in conveying, and concrete tool has the following advantages:
1, solving the problem of steel bushing upset in stopper course of conveying, by running through the inner core silk of whole stopper, contributing to the stable of stopper steel bushing;
When 2, pushing, the stress point of stopper is by near-end steel bushing, is separated into far-end and near-end simultaneously stressed, contribute to improving stopper enter sheath pipe after propelling movement performance;
When 3, reclaiming stopper, stopper occurs horn-likely lockedly to push away unblock by before inner core silk.

Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As shown in Figure 2, a kind of stopper far-end induction system composition that this utility model provides mainly contains three parts, inner core silk assembly, surrounding layer assembly and distal handle assembly.
As shown in Figure 3, inner core silk assembly comprises: the inner core silk termination 1.1 1) be connected with the far-end steel bushing of stopper, and its outside has external screw thread, and buckle 1.3 is fixed on inner core silk termination 1.1; 2) stiff wire 1.2 of inner core silk termination 1.1 and distal handle assembly is connected, the material of stiff wire 1.2 comprises the stainless steel cable of nitinol alloy wire, medical stainless steel silk, multiply nitinol alloy wire composition or the stainless steel cable of multiply medical stainless steel silk composition.
As shown in Figure 4, surrounding layer assembly comprises: the termination 2.1 1) be connected with the near-end steel bushing of stopper, termination 2.1 is hollow structure, stiff wire 1.2 can be allowed freely to pass through wherein, and the syndeton between termination 2.1 and the extreme steel bushing of stopper can be the structure that helicitic texture, buckle etc. can unlock; 2) tubing 2.2 of connection end 2.1 and distal handle assembly, stiff wire 1.2 freely passes through in tubing 2.2, and tubing 2.2 material comprises single material tubing, as stainless steel tube, stainless steel spring circle, macromolecule tubing etc. also can be the tubing that one or more materials are composited.
Distal handle assembly comprises: the control device 3.2 1) connecting and control stiff wire 1.2 length, and its material can be that one or more macromolecular materials are as nylon, polyethylene, Merlon, acrylonitrile-butadiene-styrene copolymer etc.; 2) connect and fix the handle 3.1 of surrounding layer assembly, its material can be that macromolecular material is as nylon, polyethylene, Merlon, acrylonitrile-butadiene-styrene copolymer etc.
Fig. 1 and Fig. 5 contrast can be found, after adopting this utility model, when stopper meets obstructions or bend pathological changes, due to the existence of stiff wire 1.2, far-end steel bushing can not be deflected, thus stopper can be pushed smoothly.Composition graphs 6A and Fig. 6 B, under normal circumstances, adopts this utility model and adopts existing supplying system, can reach same effect.
