Description
Technical field
The present invention relates to a kind of skin dilator, be specifically related to a kind of negative-pressure type skin external expander.
Background technology
Tissue expander art is to utilize the dilating effect acquisition additional skin soft tissue of tissue expander to carry out a kind of surgical method of skin injury reparation and Organ Reconstruction.Tissue expander art is a revolutionary achievement of field of orthopedic surgery over nearly 20 years, in the treatment such as cicatrix, superficial tumor, with the most extensive, has solved many knotty problems clinically, has replaced some skin graftings and skin flap grafting.The application of tissue expansion has not only improved orthopedic therapeutic quality, and has alleviated surgical injury.
Expansion can increase skin area, and this part additionally skin soft tissue of acquisition has three sources: 1. expansion stimulates the tissue growth of induction, and being grown in process of expansion with after expanded skin flap transfer of skin all exists.The synthetic expansion that contributes to skin area of the cell proliferation in expansion and intercellular substance material; Expanded skin flap contributes to again the recovery of skin thickness after shifting.2. creep effect, this effect is that under the effect of the biological power of being organized in, area expansion occurs or length increases, and the area of artifact tissue or the characteristic that length can not be restored are completely removed in the effect of power.And irrecoverable that a part of area or length are area or the length recruitment of tissue.Being increased by the skin area of organizing creep effect to produce is that expansion regions skin area increases the part in total amount, but the real growth that finally will be organized cell after expansion tissue transplantation replaces.3. skin soft tissue displacement, is that body skin is stressed to power source side to mobile characteristic, and the periphery of its formation expansion regions skin, is also an ingredient of expansion regions Area Growth.Obtaining in the time of transfer of skin flap of this part skin soft tissue will partly be returned to original position, and the real growth that another part finally also will be organized cell after expansion tissue transplantation replaces.
Classical dilatation is intramedullary expansion, and its basic step comprises: water filling expansion and postoperative regular water filling expansion etc. in the selection of expansion regions and dilator, the embedding art of dilator, art.Many owing to relating to technical step, treatment cycle is long, is easy to go wrong.After hematoma, infection, dilator expose and expand, flap circulation obstacle is the modal complication of skin soft-tissue expansion, and incidence rate is about 10% left and right.Because inserting of dilator needs hospitalization conventionally, water filling also needs a long-term process, causes expense relatively high.In addition, need syringe needle to treat owing to carrying out water filling, there is the very large feared state of mind for some child patients.
Skin external expander is mainly to design for above shortcoming, main by made equipment, outside skin, continuous traction skin dark purple is knitted, along with the increase of trailing weight and passing, pathological changes (as: cicatrix) skin is around extended gradually, and the skin histology that " additionally " be provided is for reparation.Tradition external skin expansion device is made up of outward expander and traction frame.Dilator is made up of jointly traction chuck, draft arm and adjustment structure thereof.Outward expander can be realized Self-operating in the family, and the skin that " generation " is newborn, for the reparation of tissue defect provides possibility.With respect to intramedullary expansion, reduce a hospitalization of embedding dilator, alleviate the difficult medical difficult problem of seeking medical advice.Outward expander can be divided into two classes at present: a class is to use the simple and crude like this articles for daily use of simple clothes airing clamp; An other class is exactly the special apparatus of price comparison costliness, operation relative complex, and cost is along with increase.
Summary of the invention
The object of this invention is to provide a kind of negative-pressure type skin external expander, the treatment phase for skin expansion is short, medical expense is low, is difficult for producing complication, and can be according to patient's individual pain ability to bear difference, set different expansion pressures, painful little, simple to operate, the position of the human body different curve of can fully fitting, also the more position of hair of fitting, can form airtight local space.
In order to achieve the above object, the present invention has following technical scheme:
A kind of negative-pressure type skin external expander of the present invention, comprise air-cushion type negative pressure cover, right angle crossover connection, connection tube, negative pressure generating device, one end of described right angle crossover connection is connected to the top of air-cushion type negative pressure cover, the other end of right angle crossover connection is connected with described connection tube, and described connection tube is connected with negative pressure generating device.
Wherein, described air-cushion type negative pressure cover comprises cover body, air bag, valve, and described air bag is connected on the edge of cover body bottom, and valve is fixed on cover body, and valve is communicated with air bag.
Wherein, crossover connection top, described right angle is provided with through hole, and this through hole is provided with top cover.
Wherein, described cover body is truncated cone-shaped, and described cover body adopts transparent material.
Wherein, described air bag cross section is tubulose, and described air bag adopts medical silica-gel.
Wherein, described valve comprises air flue, air flue lid, spring, and described air flue lid is connected with air flue, and spring top covers at air flue.
Owing to having taked above technical scheme, the invention has the advantages that:
1 the present invention is short for the treatment phase of skin expansion, medical expense is low, be difficult for producing complication, and can be according to patient's individual pain ability to bear difference, set different expansion pressures, painful little, the position of the human body different curve of can fully fitting, also the more position of hair of fitting, can form airtight local space.
2 the present invention are simple to operate, are convenient to regulate, and can eliminate Patients With Psychic Fear, solve the problem of hospitalize difficulty, improved work efficiency.
