Description
Technical field
The present invention relates to negative pressure treatment equipment technical fields more particularly to a kind of for the thin-skinned tissue defect disease of cranium jaw
Negative pressure therapeutic devices.
Background technology
The reason of cicatricial contracture, depressed scar after tissue damage, hemifacial atrophy unknown soft tissue depression class
Disease can lead to face or constitutional soft tissue defect, influence form, and especially facial lesion causes patient's appearance to be damaged, production
Raw serious mental handicape.Can there are vascularization skin flap grafting transposition of skin flap, expander skin flaps reparation for the therapy of such disease
Art and autologous fat injection transplantation etc..Wherein autologous fat injection transplantation be only by the method for suction lipectomy by body its
Its position fat takes out, and washing by bodkin is injected to soft tissue defects region after purification.Around adipocyte passes through after transplanting
Blood vessel, which is grown into, is survived, and is removed by macrophage phagocytosis between organizing after can not obtaining the Apoptosis of blood fortune.Therefore good
It is the key that successful surgery by area's soft tissue blood fortune and ductility.Since autologous fat injection transplantation wound is small, safe operation
The advantages that, it is that many patients and doctor receive.But autologous fat injection transplantation the shortcomings that there are post-transplantation fat absorptions, fat
Absorptivity is 30% to 50% after the free injection of fat.For pathological tissues, injection shot is small, and absorptivity is high, need to pass through for several times
Even ten perform the operation several times can just show slightly therapeutic effect.To find out its cause, predominantly：1. scar and pathological tissues quality are stiff, extend
Property it is poor, filling is difficult；Operation injection volume is limited every time.2. organizing poor ductility, after being implanted into lipochondrion, pressure is higher, and presses
Power, which will increase, to promote adipocyte to absorb, and lead to surgical effect decline or hour.3. diseased soft tissue blood fortune is poor, adipose tissue is planted
Bed is poor, and adipocyte Peripheral blood fortune establishes difficulty, leads to Adipocyte Apoptosis, absorbs.Soft tissue expansion is long-standing, former
Reason is that gradually extended surface skin histology, a large amount of clinical practices and research confirm that soft-tissue expansion can by built-in expansion capsule
Tissue ductility is improved, the effect of tissue blood capillary proliferation is promoted.But soft tissue expansion needs underwent operative operation that will expand capsule
In implanting tissue, patient trauma is increased.And for organizing cicatricial contracture, the tissue of hemifacial atrophy to be implanted into soft-tissue expansion
Device is easily led to the complication such as skin infection, break-through, needs to be treated using negative pressure therapeutic devices after skin infection, but existing
Some negative pressure therapeutic devices are complicated, and cost is too high, cannot popularize in an all-round way, cannot meet the needs of client.
