Abstract
The utility model provides a plugging device is filled to gel, a serial communication port, including the sacculus, the sacculus intussuseption be filled with the gel, the sacculus be connected with the one end of connecting rod, the connecting rod be hollow structure, its middle part is formed with first gel transfer passage, the inside intercommunication of first gel transfer passage and sacculus. The utility model discloses an innovation structure of sacculus is filled to the gel, does benefit to through several kilograms baby's blood vessel only to, can avoid appearing complication such as the nickel titanium ion is appeared, nickel allergy.
Description
Technical field
This utility model relates to a kind of application of gel-filled stopper, belongs to technical field of medical instruments.
Background technology
Congenital structural heart disease sickness rate is 0.9-1.2%, and Wicresoft's interventional method is a kind of modus operandi that late result is better on Clinical practice, risk is less.But be not a birth, baby just can obtain medical treatment at once, be generally to wait infant physical growth just can perform the operation to certain condition.Be because baby is too small on the one hand, be unfavorable for hands art; But more aspect is because the restriction of apparatus size.
The stopper of current use is generally adopt NiTi alloy to make, and in this metal rack, sew up several layers of choked flow film.This stopper has certain compressibility, but is not enough to by the only blood vessel of baby of several kilograms.Further, the complication such as NiTi elemental release, nickel allergy is a never clear and definite problem in science.
Summary of the invention
The purpose of this utility model is to provide a kind of stopper implanted through conduit, solves the problem that vaginula pipe is implanted, in advance for infant is performed the operation, avoids the various potential risks that traditional NiTi alloys occluder exists.
In order to achieve the above object, to be of the present utility modelly achieved through the following technical solutions:
A kind of gel-filled stopper, it is characterized in that, comprise sacculus, gel is filled with in described sacculus, described sacculus is connected with one end of connecting rod, described connecting rod is hollow structure, is formed with the first gel transfer passage in the middle part of it, and the first described gel transfer passage is communicated with balloon interior.
Preferably, described connecting rod can be sealedly and fixedly connected with push rod, and described push rod is also hollow structure, is formed with the second gel transfer passage in the middle part of it, and the second described gel transfer passage is connected with the first described gel transfer passage.
More preferably, described connecting rod is provided with female thread, and described push rod has external screw thread, and described connecting rod and push rod are threaded.
Preferably, described connecting rod is located at the outside of sacculus.
Preferably, it is the opening of 0.5-1mm that described sacculus has a diameter, and one end of described connecting rod is located at described opening part and is fixedly connected with sacculus in a welding manner.
Preferably, the wall thickness of described sacculus is at 5um-10um.
Preferably, the surface of described sacculus is provided with a medicine layer.
Compared with prior art, the beneficial effects of the utility model are:
L, this utility model adopt the innovation structure of gel-filled sacculus, are beneficial to by the only blood vessel of baby of several kilograms, and, can avoid occurring the complication such as NiTi elemental release, nickel is irritated.
2, in this utility model, connecting rod is positioned at the outside of sacculus, is beneficial to and reduces reduced size further.
3, outside of the present utility model is provided with medicine layer, can play the effect of medicine.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of stopper at heart defect place;
Fig. 2 is gel-filled stopper structural representation;
Fig. 3 is the hollow push rod schematic diagram be connected with connecting rod;
Detailed description of the invention
Below in conjunction with specific embodiment, set forth this utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of this utility model.In addition should be understood that those skilled in the art can make various changes or modifications this utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read this utility model instruction.
Embodiment 1
As shown in Figure 2, for gel-filled stopper structural representation, described gel-filled stopper, comprise sacculus 1, be filled with gel 2 in described sacculus 1, described sacculus 1 is connected with one end of connecting rod 3, and described connecting rod 3 is hollow structure, be formed with the first gel transfer passage in the middle part of it, the first described gel transfer passage is communicated with sacculus l inside.Described connecting rod 3 can be sealedly and fixedly connected with push rod 4 as shown in Figure 3, and described push rod 4 is also hollow structure, is formed with the second gel transfer passage in the middle part of it, and the second described gel transfer passage is connected with the first described gel transfer passage.Described connecting rod 3 is provided with female thread, and described push rod 4 has external screw thread 5, and described connecting rod 3 and push rod 4 are threaded.Described connecting rod 3 is located at the outside of sacculus 1.
The Mould Machining such as described sacculus 1 can use nylon, polylactic acid, rubber sizing forms, and only leaving a diameter is the opening of 1mm, and one end of described connecting rod 3 is located at described opening part and is fixedly connected with sacculus 1 in a welding manner.The wall thickness of described sacculus 1 is at 10um.The advantage of sacculus 1 is to be customized to arbitrary shape, optimally can mate pathological changes defect form.In addition, the compressibility of macromolecular material is much larger than metal material, so sacculus 1 can be delivered to heart defect place by very little sheath pipe.
The surface of described sacculus 1 is provided with a medicine layer.This medicine is the mixed liquor containing somatomedin, and somatomedin can initiatively combine with the specific receptor on the cell around defect, thus activator protein enzyme, accelerate the synthesis of protein, promote endotheliocyte metabolism, propagation and growth, the whole sacculus of final rapid Cover.
As shown in Figure 1, when sacculus l delivers to the lesion locations of interatrial septum 6 by push rod 4, by the second gel transfer passage of push rod 4, the first gel transfer passage of connecting rod 3, temperature sensitive type water gel is sent into sacculus l.Temperature-sensitive hydrogel be a class to external world the change of temperature stimulate and can make a class material of intelligent response, its main feature is the liquid for flowing under low temperature, and when the temperature increases, generally when reaching body temperature temperature, just intelligent phase in version can be there is, be converted into immobilising gel, form stopper overall, be fixed on the lesion locations place of interatrial septum 6.
