Abstract
The utility model belongs to a medical equipment technology field for beauty treatment, shaping and surgery rebuilding, which is aimed at providing a dilator of an orienting extension soft tissue. When a capsule body of the dilator is full of liquid, the dilator expands and deforms towards expected direction and the ideal skin dilating effect is achieved. The utility model comprises a capsule body, a guiding pipe and an introduction valve, wherein the capsule body is communicated with the introduction valve via the guiding pipe, the bottom of the capsule body is thickened. When the capsule body is added with liquid and expands, the tension of the bottom of the capsule body is obviously smaller than that of other portions, and enables the suffered force of the hypoderm which contacts with the bottom to be obviously decreased, thereby the capsule body expands towards to the outer side, the skin dilating achieves ideal effect, and the consequence of bad skin dilating effect due to the soft hypoderm is avoided.
Description
Technical field
This utility model relates to the soft tissue expander of the medical apparatus of a kind of beauty treatment, shaping and reconstructive surgery, particularly a kind of directed expansion.
Technical background
At present, the soft tissue expander that beauty treatment, shaping and reconstructive surgery are used be in view of skin under certain force of strain, the physiological function that natural extension, increase area are arranged, " additionally " skin that the expansion back is obtained is used for repairing the defective of proximate skin, its color and luster, quality are evenly distributed, the place is basic identical with needs, can not produce new supplying and distinguish deformity, thereby reach ideal shaping, cosmetic result.But because skin dilator adopts silicone rubber to make, can inboard tissue of compressing skin and distortion behind full liquid in the utricule, to organize when soft when this inboard, the skin effects that expands outwardly of dilator is starkly lower than desired value.
Technology contents
The purpose of this utility model is: a kind of dilator of directed expansion soft tissue is provided, can expands distortion towards the direction of expection behind the full liquid of dilator utricule, reach ideal skin expansion effect.
This utility model is achieved in that a kind of dilator of directed expansion soft tissue, comprises utricule, conduit and introduction valve, and utricule communicates with introduction valve by conduit, the bottom thickening of described utricule.
Described utricule bottom inside is attached with the thickening net.
The elasticity of described thickening net is lower than the elasticity of utricule.
The heat seal of described thickening net is in the utricule bottom inside.
This utility model is owing to adopt the utricule of bottom thickening, after utricule adding liquid expands, bottom tension is significantly less than other positions, the pressure that the subcutaneous tissue that contacts with utricule bottom is subjected to obviously reduces, utricule is expanded laterally, make skin expansion reach ideal effect, and avoided causing the consequence of skin expansion weak effect owing to subcutaneous tissue is soft.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described further.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the another kind of embodiment of this utility model.
The specific embodiment
As shown in Figure 1, the dilator of directed expansion soft tissue comprises spherical balloon 1, conduit 2 and introduction valve 3, and utricule communicates with introduction valve by conduit, and the utricule bottom inside is attached with thickening net 4.Because the elasticity that heat seal is netted in the thickening of utricule bottom inside is lower than the elasticity of utricule, so the utricule deformation of bottom is little behind full liquid in the utricule.
Certainly, utricule can be cylinder, kidney body or other respective shapes, and thickening net accordingly can be circle, rectangle and semilune.The utricule of Fig. 2 is a cylinder.
Claims (4)
1. the dilator of a directed expansion soft tissue comprises utricule, conduit and introduction valve, and utricule communicates with introduction valve by conduit, it is characterized in that: the bottom thickening of described utricule.
2. the dilator of directed expansion soft tissue according to claim 1 is characterized in that: described utricule bottom inside is attached with the thickening net.
3. the dilator of directed expansion soft tissue according to claim 2 is characterized in that: the elasticity of described thickening net is lower than the elasticity of utricule.
4. according to the dilator of claim 2 or 3 described directed expansion soft tissues, it is characterized in that: the heat seal of described thickening net is in the utricule bottom inside.
