Description
Technical field
This utility model relates to a kind of skin dilator, is specifically related to a kind of negative-pressure type skin external expander.
Background technology
The tissue expander art is to utilize the dilating effect of tissue expander to obtain a kind of surgical method that the additional skin soft tissue carries out skin injury reparation and Organ Reconstruction.The tissue expander art is a revolutionary achievement of field of orthopedic surgery over nearly 20 years, with the most extensive, has solved clinically many knotty problems in the treatments such as cicatrix, superficial tumor, 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 a part of skin soft tissue that additionally obtains has three sources: 1. expansion stimulates the tissue growth of inducing, and being grown in the process of expansion with after the expanded skin flap transfer of skin all exists.The synthetic expansion that helps skin area of the cell proliferation in the expansion and intercellular substance material; After shifting, expanded skin flap helps again the recovery of skin thickness.2. creep effect, this effect are that area expansion occurs or length increases under the effect of the biological power of being organized in, and the area of artifact sex organization or the characteristic that length can not be restored are fully removed in the effect of power.And irrecoverable that a part of area or length namely are area or the length recruitment of tissue.Being increased by the skin area of organizing creep effect to produce is that the expansion regions skin area increases the part in the 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 the power source side to mobile characteristic, and it consists of the periphery of expansion regions skin, also is an ingredient of expansion regions Area Growth.Obtaining when transfer of skin flap of this part skin soft tissue will partly be returned to original position, and another part finally also will be organized cell after expansion tissue transplantation real growth replaces.
Classical dilatation is intramedullary expansion, and its basic step comprises: water filling expansion and the regular water filling expansion of postoperative etc. in the selection of expansion regions and dilator, the embedding art of dilator, the art.Because it is many to relate to technical step, treatment cycle is long, is easy to go wrong.The flap circulation obstacle was the modal complication of skin soft-tissue expansion after hematoma, infection, dilator exposed and expand, and incidence rate is about about 10%.Because inserting of dilator needs hospitalization usually, 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, have the very large feared state of mind for some child patients.
Skin external expander mainly is to design for above shortcoming, main by made equipment, continuous traction skin dark purple is knitted outside skin, along with the increase of trailing weight and passing, so that pathological changes (as: cicatrix) skin on every side extends gradually, the skin histology that " additionally " be provided is for reparation.Tradition external skin expansion device is comprised of outward expander and traction frame.Dilator is made of jointly traction chuck, draft arm and adjustment structure thereof.Outward expander can be realized in the family Self-operating, and the skin that " generation " is newborn is for the reparation of tissue defect provides possibility.With respect to intramedullary expansion, reduced a hospitalization of embedding dilator, alleviated 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, the operation relative complex, and cost is along with increase.
The utility model content
The purpose of this utility model provides a kind of negative-pressure type skin external expander, the treatment phase that is used for skin expansion is short, medical expense is low, is difficult for producing complication, and can be different according to patient's individual pain ability to bear, set different expansion pressures, painful little, simple to operate, the position of the human body different curve of can fully fitting, the more position of hair of also fitting can form airtight local space.
In order to achieve the above object, this utility model has following technical scheme:
A kind of negative-pressure type skin external expander of the present utility model, 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 the 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 utility model has the advantage of:
It is short that 1 this utility model is used for the treatment phase of skin expansion, medical expense is low, be difficult for producing complication, and can be different according to patient's individual pain ability to bear, set different expansion pressures, painful little, the position of the human body different curve of can fully fitting, the more position of hair of also fitting can form airtight local space.
2 this utility model are simple to operate, are convenient to regulate, and can eliminate Patients With Psychic Fear, solve the problem of hospitalize difficulty, improved work efficiency.
