Abstract
The utility model relates to a skin-grafting area sealed type negative-pressure fixing device which comprises a sealing membrane (1) and a negative pressure tube (2) and is characterized in that one end of the negative pressure tube (2) is connected with central negative pressure (5), and the other end is fixed at the central position of the lower surface of the sealing membrane (1); a plurality of side holes (3) are formed in the inner tube wall of the negative pressure tube (2) and positioned in the range of the sealing membrane (1); a viscous structure is arranged on the lower surface of the sealing membrane (1). The device not only can ensure that a skin-grafting area is fixed firmly but also is simple in structure and operation and improves the survival rate of skin graft; simultaneously, the device shortens the fixing time after operations and reduces troubles caused by a fixing device to a patient and possible complications.
Description
Technical field
This utility model relates to burn and plastic surgery treatment instrument field, particularly a kind of skin-grafting area enclosed negative pressure fixture.
Background technology
For burn and shaping patient, often need to come flap coverage or replacement cicatrix zone to reach cosmetic result by skin-grafting.After skin grafting is completed, existing method is at first to pack fixing to operative region by gauze and suture, then it is firm externally to be wound around with the binder pressurization, finally fixed by Gypsum Fibrosum or support more at last, to guarantee that skin-grafting survives, to open after postoperative 5-7 days to get final product, not only structure is too fat to move but also the set time is long for this method, patient is caused inconvenience, also increased the incidence rate of the complication such as limb deep phlebothrombosis.
Summary of the invention
The purpose of this utility model is to provide a kind of skin-grafting area enclosed negative pressure fixture, and this device not only can guarantee that skin-grafting is regional fixed, and structure and simple to operate, has improved skin graft survival rate.Shorten simultaneously the postoperative set time, reduced puzzlement and the issuable complication of fixture to patient.
The technical scheme that its technical problem that solves this utility model adopts is, a kind of skin-grafting area enclosed negative pressure fixture, it comprises closing membrane and negative tube, it is characterized in that: negative tube one end is connected with central negative pressure, the other end is fixed in the center of closing membrane lower surface, the scope inner tubal wall place that negative tube is positioned at closing membrane has some side openings, and the closing membrane lower surface is the viscosity structure.
Described closing membrane covers on whole skin-grafting zone, the skin of the lower surface of closing membrane and fixed packet upper surface and the periphery formation confined space that is adhesively fixed.
Be furnished with Pressure gauge between described negative tube and central negative pressure.
Described closing membrane is the high PU thin film that thoroughly wets.
The shape of described closing membrane and skin-grafting area shape are complementary.
The lower surface bonds of described closing membrane has counterdie.
The beneficial effects of the utility model are to make the closing membrane below formation negative pressure space that is bonded on skin by the side opening on negative tube due to central negative pressure, fix thereby closing membrane well has been adsorbed on the fixed packet and to the skin graft pressurization of fixed packet and below thereof, make skin-grafting regional fixed; Act on skin-grafting area by continuous negative pressure, promoted the skin graft drain, reduced hydrops under skin graft, effectively reduced the incidence rate of ecchymosis, promoted the vascularization of skin graft and basilar part, improved skin graft survival rate; Utilize simultaneously negative pressure to promote the vascularization of skin graft and basilar part tissue.By above some, guaranteed the success rate of skin-grafting and the long-term effect of skin graft healing, also shortened the postoperative set time, reduced puzzlement and the issuable complication of fixture to patient.
Description of drawings
Below in conjunction with the embodiment accompanying drawing, this utility model is further illustrated.
Fig. 1 is this utility model structural representation;
Fig. 2 is this utility model user mode cutaway view;
In figure: 1, closing membrane; 2, negative tube; 3, side opening; 4, Pressure gauge; 5, central negative pressure; 6, skin; 7, skin-grafting area; 8, skin graft; 9, fixed packet.
The specific embodiment
As shown in this skin-grafting area closed negative pressure fixture structure schematic diagram of Fig. 1, it comprises closing membrane 1 and negative tube 2, negative tube 2 one ends are connected with central negative pressure 5, the other end is fixed in the center of closing membrane 1 lower surface, the scope inner tubal wall place that negative tube 2 is positioned at closing membrane 1 has some side openings 3, and closing membrane 1 lower surface is the viscosity structure.
During use, as shown in Figure 2, skin graft 8 for implanting on the skin-grafting area 7 of skin 6, skin graft 8 is fixing by fixed packet 9 packings of its upper surface, closing membrane 1 is covered on whole skin-grafting zone, the skin 6 formation confined space that is adhesively fixed of the lower surface of closing membrane 1 and fixed packet 9 upper surfaces and periphery, negative tube 2 one ends are between closing membrane 1 and fixed packet 9, and the central negative pressure 5 that negative tube 2 other ends pass after the confined space that closing membrane 1 is bonded in formation on skin 6 with hospital provides is connected.
Make the closing membrane 1 below formation negative pressure space that is bonded on skin 6 by the side opening 3 on negative tube 2 due to central negative pressure 5, thereby well being adsorbed on fixed packet 9 and to skin graft 8 pressurizations of fixed packet 9 and below thereof, fixes closing membrane 1, make regional fix firm of skin-grafting, thereby guaranteed the success rate of skin-grafting.
Be furnished with Pressure gauge 4 between negative tube 2 and central negative pressure 5, can accurately control the negative pressure value that provides by Pressure gauge 4, avoided the excessive or not enough adverse effect that causes of pressure, thereby realized better fixed effect.
Closing membrane 1 is high wet PU thin film thoroughly, can select the closing membrane 1 of respective shapes according to skin-grafting area 7 shapes, can be circular, square, also can be cut into respective shapes according to the difference position needs of making skin graft.Need to carry out Preservation in sterile condition before closing membrane 1 and negative tube 2 use, for guaranteeing the viscosity of closing membrane 1 lower surface, when using, the lower surface bonds of closing membrane 1 does not have counterdie, takes bed die during use off again and is bonded in desired zone.
