Abstract

The utility model discloses a composite integrated nasal prosthesis which comprises a nose bridge, a nose tip and a nasal columella. The nose bridge, the nose tip and the nasal columella are formed into an L-shaped or willow leaf-shaped smooth whole body by primary vulcanization; the back of the nose bridge is provided with a slot; and a block body which is made of expanded polytetrafluoroethylene and corresponds to the slot is adhered to the slot. The making of the composite integrated nasal prosthesis is completed by primary vulcanization; any bulge or corner angle do not exist in the nasal prosthesis; the nasal prosthesis is well attached to the nose bridge after being implanted; the die pressing times are reduced; the tensile strength of a product is improved; the cost is reduced; the expanded polytetrafluoroethylene with excellent compatibility with human body tissues is adopted; and after the composite integrated nasal prosthesis is implanted into the human body, the phenomenon of movement and ulceration of materials after the materials are implanted can be effectively prevented.

Description

The compound integral nose prosthesis

Technical field

This utility model relates to the nose prosthesis that a kind of facial plasty is filled usefulness.

Background technology

Nose prosthesis is a prosthese commonly used in the facial plasty operation, because its distinctive L shaped or wicker leaf shape structure makes the manufacturing process of nose prosthesis also different.Existing manufacture method is that nose prosthesis is divided into two sections making in the middle of the bridge of the nose, two sections is sulfided again, and causes in the middle of the nose prosthesis obvious limit being arranged, and is not enough, not attractive in appearance with human body bridge of the nose applying degree.In addition, the material that nose prosthesis is commonly used is a silicone rubber, because material is too stiff, behind the implant into body, As time goes on, nose prosthesis can produce in human body and move, and the phenomenon of ulceration takes place, and outward appearance seems also not nature.

The utility model content

The technical problem that this utility model will solve is: in the middle of overcoming existing nose prosthesis, obvious limit is arranged, profile is not attractive in appearance, and problem such as can be moved behind the implant into body provides a kind of compound integral nose prosthesis.

This utility model solves the technical scheme that its technical problem adopted: a kind of compound integral nose prosthesis; Comprise the bridge of the nose, nose and nose pillar, it is characterized in that: the described bridge of the nose, nose and nose pillar are for smoothly whole through once vulcanizing the L shaped or wicker leaf shape of forming; The back of the bridge of the nose has groove, be bonded with in the groove that expanded PTFE processes with the corresponding block of groove.

Described nose prosthesis adopts silastic material to process.

Described groove is microscler, and the block in the groove also is microscler.

The beneficial effect of this utility model is: through once sulfuration completion making, there are not any convexity and corner angle in the nose prosthesis, and better after implanting with bridge of the nose applying, reduced the mold pressing number of times, improved the hot strength of product, reduce cost; Adopt and the splendid expanded PTFE of tissue blending, behind the implant into body, can effectively prevent the generation of material moving after implanting, ulceration phenomenon.

Description of drawings

Fig. 1 is this utility model structural representation.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is further specified.

As shown in Figure 1, a kind of compound integral nose prosthesis comprises the bridge of the nose 1, nose 2 and nose pillar 3, and the described bridge of the nose 1, nose 2 and nose pillar 3 are smoothly whole for the L shaped or wicker leaf shape of forming through sulfuration once; The back of the bridge of the nose 1 has groove 11, be bonded with in the groove 11 that expanded PTFE processes with groove 11 corresponding blocks 12, described groove 11 is microscler, with groove 11 corresponding blocks 12 also be microscler.

This utility model compound integral nose prosthesis is through once sulfuration completion making, does not have any convexity and corner angle in the nose prosthesis; Surface smoothing, aesthetics and fitness improve greatly behind the implant into body, have reduced mould number of times and mold pressing number of times; Improve the hot strength of product, reduced cost.

In addition; The back fluting 11 of the bridge of the nose 1 of compound integral nose prosthesis; Bonding expanded PTFE is processed in the groove 11 and groove 11 corresponding blocks; Because expanded PTFE and tissue blending are splendid, behind the implant into body, can effectively prevent the generation of mobile, the ulceration phenomenon of material after implanting.
