Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.Embodiment of the present utility model includes but not limited to the following example.
Embodiment 1
As shown in Figure 1, 2, present embodiments provide a kind of combined type drainage tube indwelling system, this combined type drainage tube indwelling system difference from prior art is, drainage tube is made up of two parts: one is drainage tube, and another is inner support tube, and inner support tube is arranged in the pipe of drainage tube, by being applied in combination of inner support tube and drainage tube, make drainage tube under the effect of inner support tube, it is achieved diameter is variable, reach the effect of expander.On the other hand, inner support tube and drainage tube are all installed by seal wire, are achieved in accurately guiding, it is ensured that the two can arrive appointment target position.
So that those skilled in the art have apparent understanding and understanding to native system, below each parts are described in detail:
Seal wire, is mainly used in guiding function, and it includes front end and wire guides two parts, and wherein, front end is flexible termination, and wire guides is harder than front end, during use, at choledochoscope indwelling seal wire, leading section can accurately indwelling in desired location.The thickness of seal wire is not particularly limited, and when can ensure that good guiding effect and should not hindering water conservancy diversion as principle, those skilled in the art can select according to practical situation.
Inner support tube, is placed in inside drainage tube, and inner support tube is tubular structure, and it should make seal wire pass through.Inner support tube includes a support plate, supports body and fastener three part, and wherein, a support plate is arranged on the front end of inner support tube, and a support plate is coaxial with support body, and the diameter of a support plate should be more than the diameter supporting body；Fastener is arranged on the tail end supporting body, and specifically, one end of fastener is arranged on the tail end supporting body, and its other end extends to support the outside of body.The material of inner support tube is not particularly limited, but, because native system is applied to medical field, therefore it should possess environmental protection, feature to human body non-hazardous.
In the present embodiment, the shape of inner support tube is not particularly limited, and it can be circular, it is also possible to being oval, those skilled in the art can select according to practical situation.
In the present embodiment, being not particularly limited the concrete shape of fastener, it can be arbitrary planform possessing fastener effect, and in present specification accompanying drawing, the shape of fastener should not limit the protection domain of the application.
In order to realize being realized the expanding effect of drainage tube by inner support tube, in the present embodiment, fastener is the fastener of scalable resilience, concrete, fastener is arranged on support body by spring, simultaneously, it is available for groove or the hole that fastener is absorbed in supporting to be provided with on body, when by lower fastener (now spring is compressed), fastener is absorbed in support body, then, when external force is cancelled, fastener resilience under the effect of spring-return power again, the rebound height supporting body upper fastener determines the diameter (distance between symmetrical fastener outermost end) of drainage tube.
Drainage tube, for main drainage pipe, in the present embodiment, the tube wall flexible of drainage tube, has support effect, and drainage tube should make seal wire pass through.Drainage tube mainly includes drainage tube main body, fixation balloon, water filling or gas tube, draw-in groove.Wherein, fixation balloon is arranged on the front position of drainage tube main body, and draw-in groove is arranged on the tail end of drainage tube main body, and its particular location should be with when inner support tube be installed with drainage tube, and after fastener ejects, fastener upper end is as the criterion in can snapping in draw-in groove；Further preferred scheme, in the present embodiment, draw-in groove is double notchs, and the twin-stage that thus can realize drainage tube diameter is variable.
In the present embodiment, the shape of drainage tube is not particularly limited, and it can be circular, it is also possible to being oval, those skilled in the art can select according to practical situation.As a kind of optimal way, in the present embodiment, drainage tube is consistent with the holding of the shape of inner support tube, the two only difference on the bore (diameter) and/or length of pipeline.
In the present embodiment, fixation balloon is annular air-pocket, under original state, there is not liquid or gas in fixation balloon, and it is in compressive state, now, can be easy to the installation of drainage tube；After exiting seal wire, when needs stones in intrahepatic bile duct is supported, by water filling or gas tube by water filling in the fixation balloon of front end when guaranteeing that drainage tube is in place, can make air bag diameter relatively drainage tube about 2mm, thus reach interior fixing effect.Wherein, for being inflation or water filling in fixation balloon, can select according to practical situation, it is generally preferable that be water filling.
In the present embodiment, the front end of drainage tube main body is double circle cross drainage heads, by this design, on the one hand, can ensure passing through of seal wire, on the other hand, can reach abundant drainage effect under fixing inner support tube premise.Wherein, the structure of double round cross drainage heads, as in figure 2 it is shown, its center is circular or oval through-hole structure, is disposed with the structure in " ten " font at end face.
When mounted, a support plate of inner support tube front end supports the front end of described drainage tube, and the fastener of the tail end of inner support tube snaps in the draw-in groove of described drainage tube tail end.
The using method of native system is as follows: (1), at choledochoscope indwelling seal wire, the indwelling of seal wire front end is in desired location；(2) insert inner support tube along seal wire and drainage tube arrives target site；(3) the fixing external end of drainage tube, presses the fastener in lower inner support tube and enters the draw-in groove of drainage tube so that drainage tube bullet extends suitable diameter；(4) seal wire is exited, water filling or inflation in fixation balloon, fixing drainage tube.
Embodiment 2
The present embodiment difference from embodiment 1 is, the shape of air bag is different, and in the present embodiment, air bag uses the air bag of non-circular shape.
Embodiment 3
The present embodiment difference from embodiment 1 is, double round cross drainage heads are non-circular double circle, but uses oval double circles (bielliptic(al)).
According to above-described embodiment, this utility model just can be realized well.What deserves to be explained is; on the premise of above-mentioned design principle; for solving same technical problem; even if some made on architecture basics disclosed in the utility model are without substantial change or polishing; the essence of the technical scheme used is still as this utility model, therefore it should also be as in protection domain of the present utility model.
