Description
Technical field
The present invention relates to a kind of skin dilator, be specifically related to a kind of negative-pressure type external skin expansion
Device.
Background technology
Tissne expousd is that the dilating effect utilizing tissue expander obtains additional skin soft tissue
Carry out a kind of surgical method of skin injury reparation and Organ Reconstruction.Tissne expousd is nearly 20
A revolutionary achievement of field of orthopedic surgery over Nian, uses in cicatrix, superficial tumor etc. are treated
The most extensive, solve many knotty problems clinically, instead of some skin graftings and skin
Lobe transplantation.The application of tissue expansion not only increases orthopedic therapeutic quality, and
Alleviate surgical injury.
Expansion can increase skin area, and the extra skin soft tissue obtained of this part has three to come
Source: 1. expansion stimulates the tissue growth of induction, being grown in process of expansion and expansion skin of skin
All exist after lobe transfer.Cell proliferation and the synthesis of intercellular substance material in expansion contribute to skin
The extension of skin area;The recovery of skin thickness is contributed to again after expanded skin flap transfer.2. creep effect
Should, this effect be the biological power of being organized in effect under area occur extension or length increase, and
The effect of power release after the characteristic that can not restore completely of the area of biological tissue or length.And not
That a part of area that can restore or length are i.e. area or the length incrementss of tissue.By organizing
It is in the skin area growth total amount of expansion regions that the skin area that creep effect produces increases
Point, but finally to be replaced by histiocytic real growth after expansion tissue transplantation.3. skin
Skin soft tissue, is the characteristic that moves to direction, power source of body skin stress, and it constitutes expansion
The periphery of district's skin, is also an ingredient of expansion regions area growth.This part skin
The acquisition of skin soft tissue wants partial recovery to original position when transfer of skin flap, and another part is final
Also to be replaced by histiocytic real growth after expansion tissue transplantation.
Classical dilatation is intramedullary expansion, and its basic step includes: expansion regions and the choosing of dilator
Select, water filling expansion and postoperative regular water filling expansion etc. in the embedding art of dilator, art.Owing to relating to
Technical step is many, and treatment cycle is long, it is easy to go wrong.Outside hematoma, infection, dilator
After dew and expansion, flap circulation obstacle is the modal complication of skin soft-tissue expansion, occurs
Rate is about about 10%.Owing to inserting of dilator typically requires hospitalization, water filling also needs
Want a long-term process, cause expense of a relatively high.Further, since carry out water filling needs
Syringe needle is treated, and has the biggest feared state of mind for some child patients.
Skin external expander is primarily directed to above shortcoming design, main by made dress
Standby, knit at the outer continuous traction skin dark purple of skin, along with the passage of the increase sum of trailing weight, make
Obtain pathological changes (such as: cicatrix) skin around gradually to extend, it is provided that the skin histology of " additionally "
It is used for reparation.The outer extension fixture of Traditional skin is made up of outward expander and traction frame.Dilator
Collectively constituted by traction chuck, draft arm and adjustment structure thereof.Outward expander is capable of being in
Self-operating in front yard, the skin that " generation " is newborn, the reparation for tissue defect provides possible.
Relative to intramedullary expansion, decrease a hospitalization of embedding dilator, alleviate difficulty of seeking medical advice
Medical problems.Outward expander can be divided into two classes at present: a class is to use simple clothes airing clamp
The simplest and the crudest articles for daily use;An other class is exactly the special apparatus that price comparison is expensive, operation
Relative complex, cost is along with increase.
Summary of the invention
It is an object of the invention to provide a kind of negative-pressure type skin external expander, for skin expansion
The treatment phase is short, and medical expense is low, is not likely to produce complication, and can be according to the individual of patient
Pain ability to bear is different, sets different expansion pressures, painful little, simple to operate, it is possible to
Fully the position of laminating human body different curve, the position that hair of also fitting is more, can be formed close
Close local space.
In order to achieve the above object, the present invention has a following technical scheme:
A kind of negative-pressure type skin external expander of the present invention, turns including air-cushion type negative pressure cover, right angle
Changing pipe, connecting tube, negative pressure generating device, one end of described right angle crossover connection is connected to air-cushion type
The top of negative pressure cover, the other end of right angle crossover connection is connected with described connecting tube, described connecting tube
It is connected with negative pressure generating device.
Wherein, described air-cushion type negative pressure cover includes cover body, air bag, valve, and described air bag connects
On edge bottom cover body, valve is fixed on cover body, and valve connects 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 uses transparent material.
Wherein, described balloon cross-sectional is tubulose, and described air bag uses medical silica-gel.
Wherein, described valve includes air flue, air flue lid, spring, and described air flue lid is with air flue even
Connecing, spring top is on air flue lid.
Owing to taking above technical scheme, it is an advantage of the current invention that:
1 present invention is short for the treatment phase of skin expansion, and medical expense is low, is not likely to produce concurrent
Disease, and can be different according to the individual pain ability to bear of patient, set different expansion pressures
Power is painful little, it is possible to the position of human body different curve of fully fitting, hair of also fitting is more
Position, airtight local space can be formed.
2 present invention are simple to operate, it is simple to regulation, can eliminate Patients With Psychic Fear, solve patient
The problem of difficulty of seeking medical advice, improves work efficiency.
