From a wig portion having hairs of the same type implanted and having a shape corresponding to the head of the user, and at least one joint provided between the outer edge of the prosthesis portion and an appropriate position of the joint. Is achieved by a facial prosthesis consisting of:

According to the present invention, since the prosthetic part is fixed to the wig part via the joint part, the prosthetic part is supported by the wig part on the head of the user during the attachment. It can be mounted easily and securely, and can be accurately mounted in place.

〔Example〕

Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings.

FIG. 1 shows an embodiment of a facial prosthesis according to the present invention. The face prosthesis 1 has a face defect portion 3 of the user 2 on the inner surface.
The prosthesis portion 1a is formed in a shape corresponding to the defect shape and the outer surface is formed in an appropriate prosthesis shape so as to exhibit the normal facial shape of the user, and the outer edge portion of the prosthesis portion 1a. At least one joint portion 1b provided integrally
And a wig portion 1c having a shape corresponding to the head shape of the user 2 and fixing the joint portion 1b at an appropriate position on the inner surface. In this example, the facial defect portion 3 is missing on the left forehead, the orbit and the cheek.

The prosthesis part 1a is molded integrally with the joint part 1b with, for example, a silicone resin, and preferably the joint part 1b is embedded with at least one net 4 (see FIG. 2) at the time of molding. This increases the strength of the joint part 1b. Where the first
In the figure, the inner surface of the prosthesis portion 1a refers to the entire area corresponding to the defect form of the facial defect portion 3, and the outer surface of the prosthesis part is a portion formed by imagining the normal facial form of the user. .

The wig portion 1c is preferably provided with at least one conventionally known stopper (not shown), by which the user's hair is pinched and securely attached to the user's head. The wig portion 1c is joined to the wig base B at at least one joint portion 1b of the prosthesis portion 1a, and the joint portions 1b and the wig base B are covered without being exposed by the hairs H that are planted on the outer surface in large numbers. Covered.
An appropriate material such as artificial skin or a net is used as the material of the wig base B, and the shape of the wig portion 1c may be a partial wig or a whole wig as appropriate.

The joining portion 1b is fixed to the wig portion 1c by adhesion or sewing, but in the case of sewing, preferably the third portion is used.
As shown in the figure, a thin plate 5 made of metal or the like having a plurality of holes for sewing threads is arranged on both sides of the joint 1b, and the joint 1b and the thin plate 5 are sewn together to the wig portion 1c. Thus, the joint
The intensity of 1b is further increased.

Since the embodiment of the present invention is configured as described above, when the wig member 1c is put on the head of the user 2 and positioned at a predetermined position when the prosthesis is attached, the prosthesis portion 1a is moved by the user. Two
Since it can be placed at a predetermined position with respect to the facial defect portion 3 of
Here, the wig portion 1c is fixed to the head of the user 2 by holding the hair of the user by a stopper (not shown) fixed to the inner surface of the wig base B, and the prosthetic portion supported by the wig portion 1c accordingly. 1a is fixed in place. After positioning the prosthesis portion 1a, if the peripheral edge portion is adhered to the periphery of the facial defect portion 3 with an adhesive, the prosthetic portion 1a is fixed more firmly.

Next, an example of a method for manufacturing the facial prosthesis 1 in the above-described embodiment will be described. First, an impression material such as alginate is applied to the facial defect portion 3 of the user 2 to mold the first female mold, Gypsum slurry is poured into the first female mold and hardened to produce a male defect model. Subsequently, clay or paraffin is waxed up to the defective model to virtualize a normal facial morphology and shape the molding part. At that time, for example, the joint portion is formed on the extension of the forehead portion.

Next, the molding portion and the joint portion separated from the defect model are attached to the user, and the forms of the fine adjustment portion such as wrinkles, pores and their peripheral portions are adjusted. After that, prepare two metal flasks each filled with gypsum slurry, immerse the molding part and the joint part where the release agent is applied to the entire surface in the gypsum slurry in one metal flask, and in the other metal flask The defect model coated with the release agent is dipped in the gypsum slurry of No. 2 to polymerize the two flasks and dry-harden. After the plaster is hardened, the paraffin wax is waxed and the defect model is peeled off to complete a second gypsum female mold having voids corresponding to the shapes of the defect model, the molding part and the joint part.

Finally, after applying a release agent to the second and female molds, silicone resin is filled and vulcanized, and after the silicone resin is cured, the prosthesis part 1a is peeled off from the second female mold.
And the joint part 1b is completed. Incidentally, at the time of filling with this silicone resin, if at least one or more nets are set in the concave portion corresponding to the joint, the net will be embedded in the silicone after the silicone is cured. , The joint is strengthened.

FIG. 4 shows another embodiment of the present invention, in which the prosthesis portion is formed hollow on the inner surface side as indicated by reference numeral 1a '. As a result, the weight of the prosthesis portion can be reduced, and the prosthesis can be attached more easily.

In each of the above-mentioned embodiments, the joint portion 1b may be formed separately from the prosthesis portions 1a and 1a ', or may be integrally attached to the peripheral portion of the wig portion 1c.
Further, the prosthesis portion may be molded using a foamed resin such as latex foam or soft polyurethane foam. When the foamed resin is used, the weight of the prosthesis portion is reduced, so that the burden on the user is reduced. Further, as a case to which the present invention is applied, in addition to the case where a part of the face described above is missing, it can be significantly applied to a case where the outer surface of the skin has a keloid shape due to a burn or the like, and the term of the defect portion is It is intended to include those of these cases.

〔The invention's effect〕

As described above, according to the present invention, since the prosthesis portion is fixed to the wig portion via the joint portion, when mounting,
The prosthesis portion is placed at a predetermined position relative to the facial defect portion of the user by simply covering the head portion of the user with the wig portion and positioning the wig portion by operating the stopper of the wig portion. It is fixed to the user's head and thus the prosthetic part is held in place by being supported by the wig part. Thus, the facial prosthesis can be easily and surely attached and fixed to the predetermined position, and can be accurately positioned at the predetermined position.
