Description
Technical field
This utility model belongs to medical instruments field, particularly a kind of negative pressure microgranule bark fetching skin-grafting device.
Background technology
Skin transplantation is called again skin grafting, for large-area wound, burn and some other particular procedure that needs cutify, is to utilize autologous or allosome skin graft to be transplanted to skin injury region, makes wound healing; Or the method that need to reproduce body surface organ because of shaping.Skin grafting mainly comprises free skin grafting and skin flap grafting.Common dermatoplastic method has the transplanting of sword pachydermia, split thickness skin graft transplanting, full thickness skin graft to transplant at present, their shortcoming is: at least will be at large-area skin histologies such as skin donor site acquisitions, wound is caused in skin donor site, and in migration process, need to frequently change dressings and observe wound surface skin survival condition, the loaded down with trivial details check of program.Micrograiting (MicroskinGraft, MSG) is existing clinical practice technology, but general by manual operations, once traumatic infection, small skin island is easily engulfed by antibacterial.Wound-surface negative pressure treatment (negative-pressurewoundtherapy, NPWT) is novel vacuum suction system, can be under suction function, promote the growth of wound surface granulation tissue, alleviate local inflammation edema, but generally also need secondary skin-grafting, self inanimate object is repaired property.In recent years, there is some scholars to explore the auxiliary sword pachydermia of application NPWT and transplanted, but the report that also not auxiliary microparticle skin is transplanted at present.
Summary of the invention
For the problems referred to above, this utility model provides a kind of negative pressure microgranule bark fetching skin-grafting device, this device installs by a bottom can that screen cloth grinds aperture cutter head, can extract negative pressure, NPWT sponge and vacuum suction machine form, can seal cover directly connects vacuum suction machine, NPWT sponge is placed in metal case, and screen cloth grinds aperture cutter head and is installed on can box body bottom, directly contacts with the one side of NPWT sponge.
During bark fetching, NPWT sponge is placed in to can, sealing metal box, grinds aperture cutter head by screen cloth and is placed in and treats on bark fetching skin, opens vacuum suction machine, and behind vacuum suction Chu Pi island, to frustrating bark fetching, skin island rule adheres on NPWT sponge;
During skin-grafting, open can, take out sponge and be covered in wound surface, external application diaphragm seal, connects negative tube, forms negative pressure, and bark fetching skin-grafting process is complete.
The tool bore aperture that described screen cloth grinds aperture cutter head is 1.0mm, and dot matrix is arranged.
Pressure 100～the 150mmHg of external connecting negative pressure attractor during operation, regulates according to bark fetching position skin thickness.
This utility model can be integrated the steps such as microgranule bark fetching, skin-grafting, vacuum suction, greatly shortens the treatment time of operation, has practicality.Concrete technical advantage is:
1) three-dimensional bark fetching: break through traditional bark fetching mode, each tapered skin island comprises holostrome Skin Cell.
2) raise the efficiency: microparticle skin manufacturing process automatization, greatly shorten operating time.
3) flexible operation: supply district's bark fetching repeatedly, not limited by bark fetching position.
4) innovation and application: the auxiliary microparticle skin of vacuum drawing technique is transplanted, and for common clinical, frequently-occurring disease, has potential applicability in clinical practice widely.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model device,
Fig. 2 is the schematic diagram using after this utility model device bark fetching,
Fig. 3 is SD rat dorsal part wound surface skin-grafting schematic diagram,
Wherein 1 is can seal cover, and 2 is can box body, and 3 is NPWT sponge, and 4 is screen cloth grinding aperture cutter head, 5 vacuum suction connection tubes, 6 tool bores for screen cloth grinding aperture cutter head, 7 is microparticle skin, 8 is medical diaphragm seal, and 9 is vacuum suction connection tube, and 10 is wound surface.
The specific embodiment
This utility model provides a kind of negative pressure microgranule bark fetching skin-grafting device, this device installs by a bottom can that screen cloth grinds aperture cutter head 4 and can extract negative pressure, NPWT sponge 3 and vacuum suction machine 6 form, can seal cover 1 directly connects vacuum suction machine 6, NPWT sponge 3 is placed in metal case 2, screen cloth grinds the bottom that aperture cutter head 4 is installed on can box body 2, directly contacts with the one side of NPWT sponge 3.
High being respectively of described can length and width (greatly) 10 * 10 * 1cm, (in) 5 * 5 * 1cm, tri-models of (little) 3 * 3 * 1cm.
The quantity that described screen cloth grinds the tool bore of aperture cutter head be (greatly) 48 * 48, (in) 24 * 24, (little) 13 * 13.
The quantity that described screen cloth grinds the tool bore 6 of aperture cutter head is 13 * 13.
Pressure 100～the 150mmHg of external connecting negative pressure attractor 5 during operation (regulating according to bark fetching position skin thickness).
During bark fetching, NPWT sponge 3 is placed in to can, sealing metal box, grinds aperture cutter head 4 by screen cloth and is placed in and treats on bark fetching skin, opens vacuum suction machine, and behind vacuum suction Chu Pi island, to frustrating bark fetching, microparticle skin rule adheres on NPWT sponge.
During skin-grafting, open can, take out NPWT sponge 3, be covered in wound surface 10, external application diaphragm seal 8, connects vacuum suction connection tube 9, forms negative pressure, and skin-grafting process is complete.
Adopt this to use novel negative pressure microgranule bark fetching skin-grafting device to carry out bark fetching skin grafting to 100 routine SD rats and 10 routine patients, bark fetching skin operating time of planting, make skin graft is short, without infection conditions, occur, be subject to Ji Gong district, district on average in 15 days, to recover (skin covers completely), without clear scar hypertrophy.
