Abstract
A new style dilator with a guided drug system comprises an expander capsule, a pipe and an injection pot, wherein the two ends of the pipe is respectively communicated with the expander capsule and the injection pot. The expander capsule comprises an internal capsule and an external capsule with the internal capsule locating outside the external capsule. The injection pot has two pots, one of which is the internal pot connected with the internal capsule by a pipe, the other one of which is the external pot communicated with the external capsule, on the wall of which several millipores are, by another pipe. The internal capsule of the utility model plays the same role as the present dilator, but between the internal capsule and the external one drugs can be injected through the external pot. Drugs are diffused to the surrounding tissue by the millipores of the external capsule. Under the interaction of the biochemical effect and mechanical stimulation of the drug, tissue metabolism is accelerated and tissue expansion is promoted. The new style dilator is proven to be capable to improve the speed of tissue expansion and reduce the relaxation shrinkage as well by animal and clinical application.
Description
Technical field
This utility model relates to a kind of novel expanded device with drug guide system, is used in the expansion of plastic surgery operations to skin soft tissue.
Background technology
Currently used soft tissue expander is made up of the conduit of expanding capsule, injection kettle and be connected in them between the two.To expand capsule during use and imbed in the skin, make the purpose of expanding the expansion of capsule mechanicalness and reaching tissue expander with simple pump pickle.The expansion cycle long (6-8 week) that adopts this kind dilator to need, various Rapid Expansion method sharp ache, the patient is difficult to connect love, and expands the relaxation shrinkage height of the flap that, and actual value is low.
Summary of the invention
The purpose of this utility model just provides a kind of patient suffering, raising spreading rate, novel expanded device of the band drug guide system that the flap relaxation shrinkage is little of not increasing.
The technical solution of the utility model is: comprise expansion capsule, conduit and injection kettle, the two ends of conduit are communicated with expansion capsule and injection kettle respectively, and described expansion capsule is made up of capsula interna and external capsule, and capsula interna is positioned at external capsule; Described injection kettle has two, and one is interior kettle, is communicated with described capsula interna by a conduit; Another is outer kettle, is communicated with described outer kettle by another root conduit; A plurality of micropores are arranged on the cyst wall outside described.
Described micropore size is about 300 μ m, thickly distributes by dredging gradually to far-end from the nearly duct entry end of external capsule.
The top of kettle and outer kettle is respectively hemispherical and mesa-shaped in described.
Capsula interna of the present utility model is identical with existing dilator effect, and can pass through outer kettle injectable drug between the interior external capsule, go in the tissue around medicine is diffused into by the micropore on the outer cyst wall, by the biochemistry influence of medicine and the common work of mechanical stimulus, accelerate tissue metabolism, promote tissue expander.Proved all that through animal and clinical practice it can improve the relaxation shrinkage that tissue expander speed has also reduced flap.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model;
Fig. 2 is the structure cross-sectional schematic of the outer kettle of this utility model;
Fig. 3 is the structure cross-sectional schematic of kettle in this utility model.
The specific embodiment
Referring to Fig. 1-Fig. 3, this utility model comprises expansion capsule, conduit and injection kettle, and described expansion capsule is made up of capsula interna 1 and external capsule 2, and capsula interna 1 is positioned at external capsule 2; Described injection kettle has two, and one is interior kettle 3, is communicated with described capsula interna 1 by a conduit 4, and another is outer kettle 5; Be communicated with described outer kettle 5 by another root conduit 6; A plurality of micropores 7 are arranged on the wall of described external capsule 2.
The aperture of described micropore 7 is about 300 μ m, thickly distributes by dredging gradually to far-end from external capsule 2 nearly duct entry ends.
For the ease of difference, the top of described interior kettle 3 and outer kettle 4 is respectively hemispherical and mesa-shaped, sees also Fig. 2 and Fig. 3.
When using this utility model, should be earlier when per injection the outside kettle 5 injections medicine papaverine etc. (for prevention infection and the pain when preventing skin expansion also can add) for example that is used to suppress fibrous capsule contracture and nutrition expansion regions flap around the dilator, inside injecting normal saline in the kettle 3 immediately then with antibiotic and lignocaine etc.Pressure in the time of can fully relying on capsula interna 1 to expand like this extrudes the medicinal liquid in the exocoel (between the interior external capsule) by the micropore on the outer cyst wall, be diffused into and go to bring into play pharmacological action in the surrounding tissue.
Claims (3)
1, a kind of novel expanded device with drug guide system comprises expansion capsule, conduit and injection kettle, and the two ends of conduit are communicated with expansion capsule and injection kettle respectively, it is characterized in that:
