Abstract
The utility model discloses a personalized directional expander with a lockable sleeve on an outer surface of a utricle body, wherein the personalized directional expander with the lockable sleeve on the outer surface of the utricle body can satisfy a personalized scheme and design demands according to an actual flap. Compared with a common expander, the personalized directional expander with the lockable sleeve on the outer surface of the utricle body is characterized in that after the utricle body of the expander is filled with liquid, the utricle body can expand and deform towards a predicted direction so that the expander after expanding is enabled to be molded step by step, the flap is enabled to expand towards the predicted direction, and therefore desired skin lobe expanding effect is achieved. The personalized directional expander with the lockable sleeve on the outer surface of the utricle body comprises a utricle body, a catheter and an injection valve. The utricle body is communicated with the injection valve through the catheter. A round sleeve with holes is stuck on the outer surface of the utricle body. The position, provided with the round sleeve, of the utricle body is thickened. An inextensible or a low-dilation-coefficient (coefficient of dilation of the belt is lesser than that of the utricle wall) belt penetrates through a plurality of sleeve rings and then is locked. When the utricle body is filled with liquid and expands, the utricle body expands towards the portion without the belt penetrating, and the flap is enabled to expand to achieve a predicted and desired effect, and reasonable using the flap in a two-stage operation is guaranteed.
Description
Technical field
This utility model relates to the medical apparatus of a kind of beauty treatment, shaping and reconstructive surgery, particularly a kind of dilator of directed expansion flap of satisfying personalized Design of Flap requirement.
Background technology
Dilator is skin-grafting apparatus commonly used in the plastic surgery operations, the existing plastic surgery process of using dilator be dilator is placed on selected intact subcutaneous, utilize syringe in the introduction valve regularly saline injection the expansion capsule is expanded gradually, effects on surface skin produces pressure, its expansion is stretched, so that the skin soft tissue of " additionally " to be provided, and utilize the skin soft tissue that increases newly to shift to repair contiguous or the position of soft tissue defects at a distance.Because the soft tissue defects position is different, the flap that conventional kidney type or cylindrical expander expand out can not satisfy the true form requirement well, it is inadequate particularly to design the imperfect flap area that often causes, if tractive is sewed up reluctantly, postoperative is prone to the poor flap necrosis that causes of blood fortune.Therefore, a kind of personalized dilator by set direction expansion of development is the key of the existing dilator of improvement.
Summary of the invention
For solving the problems of the technologies described above, this utility model provides a kind of directed expansion device of utricule outer surface belt lockable cover, and is with the utricule at cover position to thicken, and can expand by actual demand after it inserts body surface, reduces the loss of flap and reduces wound area.
This utility model is to realize by following technical scheme:
A kind of personalized directed expansion device of utricule outer surface belt lockable cover, comprise utricule, conduit and introduction valve, utricule communicates with introduction valve by conduit, and described utricule outer surface is attached with the circle cover that is fixed on the utricule surface with holes, and circular cover can be at any position of utricule outer surface.
Described circular cover around the position utricule thicken.
Described circular cover with holes can pin and be fixed on the utricule surface less than the belt of dilator cyst wall by non-telescoping or coefficient of dilatation.
Described circular cover and utricule adopt medical grade silicon rubber or have the harmless material material of elastic nontoxic high molecular to be made.
Described cover thickens utricule elasticity around the position and is lower than other position utricule.
This utility model is owing to controlled the direction that expansion capsule utricule expands, after utricule adding liquid expands, except the utricule that is lockable the position is not expanded, other utricule that is not lockable the position is expanded to set direction, make the dilator after the expansion be able to progressively plastotype, so that flap is to default plastotype direction expansion, thus satisfying personalized Design of Flap demand, design difform flap, guaranteed the blood fortune of postoperative skin flap and avoided unnecessary wound.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is 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 tissue comprises utricule 1, conduit 2 and introduction valve 3, utricule communicates with introduction valve by conduit, the utricule outer surface is attached with fixing with holes circular cover 4, circular ring thickens cyst wall 5 around the position, and cover is locked in the belt 6 that the utricule outer surface passes circular cover aperture.Because lasso trick has belt non-telescoping or coefficient of dilatation little (coefficient of dilatation is less than the dilator cyst wall) to add thickening of the corresponding bladder walls of belt, mean that its elasticity is lower than other not elasticity of restricted part cyst wall, the soft-tissue expansion of its corresponding position is limited, not limited position obtains expansion, make the dilator after the expansion be able to progressively plastotype, so that flap is to default plastotype direction expansion, thereby thereby satisfying personalized Design of Flap demand expands the flap of realistic demand.
Need to prove, any equivalent way that those skilled in the art have done in the scope of this description, or obviously variant all should be in protection domain of the present utility model.
Claims (5)
