Abstract

The utility model relates to an internally planted type mammary prosthesis with surface expanding wrinkles, which is composed of colloid or liquid. The utility model is characterized in that part of or all the surface of the mammary prosthesis is provided with rugged expanding wrinkles. When in horizontal and static arrangement, envelope lines of the mammary prosthesis are circular in the projection of downward looking direction or upward looking direction, and form a bow shape in the projection of side looking direction. The concave convex depth of the expanding wrinkles and the curvature radius of a wrinkle curve form various regular or stochastic variations corresponding to the circle center of the surface of the mammary prosthesis. A convergence region of the expanding wrinkles is arranged in the geometric center of the upper surface. The concave convex depth of the expanding wrinkles changes in the range of 3 to 15 mm. The change range of the radius of wrinkle curve arcs is 1/20 to 1/2 of the diameter of the circular envelope lines of the mammary prosthesis. The number of the expanding wrinkles in the geometric centre of the upper surface of the mammary prosthesis is three to eight. The continuous expanding wrinkles are uniformly distributed in the round angle range, and the rest is discontinuous expanding wrinkles in a centripetal way or a non centripetal way. The utility model is provided with contraction rugae with large specific surface area and relief of tissue peplos.

Description

Internal implanted mammary prosthese with surperficial expanding wrinkle

[technical field]

This utility model relates to plastic surgery's utensil, and specifically it relates to a kind of structure of breast interplantation prosthese.

[background technology]

Existing breast prosthesis has various three-dimensional shapes, its bump surface also has various forms such as hemisphere face, the semiellipse face, or the combined shaped of various three-dimension curved surfaces, no matter but any shape, its surface is smooth surface, the surface no concave-convex changes, its shortcoming is: comparatively speaking, the specific surface area of smooth surface utricule (being the surface area under the equal volume) is less relatively, when the pressure that is subjected on every side, content such as the colloid contained in the surface, the change in volume of liquid will be very little, but the surface of cyst membrane will be subjected to the pressure of normal direction and tangential surface shear power, and corresponding gauffer distortion takes place, corresponding intrinsic pressure can the increase, hardening.Equally for breast prosthesis, in case behind the implant into body, promptly can around it, slowly form muscle fiber and organize peplos, and peplos to have the nature shrinkage surface long-pending be the trend of contracture, and this will certainly the surperficial forming method of the breast prosthesis of implanting to pressure and tangential surface shear power, these two kinds of power all can form extruding to breast prosthesis, cause the breast prosthesis areal deformation to be shunk, its result will cause the whole hardening of breast prosthesis, even cyst membrane breakage, seepage, not only cause the distortion of breast outward appearance to uglify, and bring spirit and human body misery can for implanted person.The last breast prosthesis that forces the operation receiveing person to perform the operation once more and take out prosthese or more renew toward contact; Bring the dual loss of economy and body and mind to the operation receiveing person.

U.S. Pat 5,480,430 have announced a kind of liquid filling breast prosthesis, it is characterized in that double-deck utricule, and the thickness distribution of cyst membrane realizes a kind of special elastic construction about before and after utilizing, to reach contracture and the whole hardened purpose of alleviating the breast prosthetic implant surface.European patent FR2726173 also discloses similar structure in addition, in the hope of reaching identical functions; But because the pressure of normal direction can only be partly alleviated in these improvement, surface shear power for tangential direction then can't be alleviated, therefore, expect these the structural change of publication be difficult to that the crease-resistant and anti-contracture function of breast prosthesis is had substantial improvement.

[summary of the invention]

Promptly contrast the problems referred to above and the defective of patent documentation at prior art, technical problem to be solved in the utility model is that a kind of internal implanted mammary prosthese with surperficial expanding wrinkle that has bigger serface more, can alleviate the contracture gauffer effect of organizing the peplos surface will be provided.

For this reason, a kind of internal implanted mammary prosthese with surperficial expanding wrinkle as technical solution of the present utility model is made of colloid or liquid, and it is characterized in that: the part or all of surface of described breast prosthesis has rough expanding wrinkle.

When level left standstill, some ad-hoc location on the relative breast prosthesis of the radius of curvature surface of the concavo-convex degree of depth of described expanding wrinkle and texture curve presented multiple rule or variation at random.

The ad-hoc location on described breast prosthesis surface is the upper surface of breast prosthesis, the geometric center of lower surface, is provided with the assembling area of expanding wrinkle at the geometric center place of upper surface.

The envelope of described breast prosthesis is circular in the projection of bowing or look up direction, is arc in the projection of side-looking direction.

The excursion of the concavo-convex degree of depth of described expanding wrinkle is 0.5-25mm, preferred 1-12mm; The excursion of the radius of the texture curve arc of described expanding wrinkle is the 1/50-1/2 of the circular envelope diameter of breast prosthesis, preferred 1/20-1/3.

The continuous expanding wrinkle of crossing the upper surface geometric center assembling area of described breast prosthesis is the 3-8 bar, and these continuous expanding wrinkles uniform distribution in all angle ranges; All the other expanding wrinkles are entad or non-entad discontinuous expanding wrinkle.

Since in moulding process to the cyst membrane surface forming of breast prosthesis the arcual expanding wrinkle of combination, in filling in breast prosthesis cyst membrane of the present utility model behind colloid or the liquid filler material, it is few to keep the constant and volume of cyst membrane envelope shape to increase, it is flat by support to keep making up the arc expanding wrinkle again, and promptly specific surface area increases greatly.Like this, not only can induce muscle fiber peplos also to enlarge its surface area at the expanding wrinkle gauffer of the lip-deep distributed in three dimensions of breast prosthesis, even the peplos surface area shrinks, because the rich very big adjustment surplus of the expanding wrinkle gauffer on the surface of the breast prosthesis of implanting, so whole breast prosthesis still can be made very big strain, can greatly alleviate peplos to the colloid of content or the normal direction pressure and the tangential direction shear stress of liquid formation, have obvious, definite function eliminating muscle fiber capsule contracture and sclerosis; In addition, this utility model is relatively large because of specific surface area, and is bigger for fluid or its removable space of colloid of equal volume, deformation range is big, therefore being convenient to the doctor implants breast prosthesis under Wicresoft's wound condition, has reduced operation receiveing person's misery, has improved the quality of plastic operation.
