Abstract
The present invention relates to a composite nasal prosthesis. The nasal back part of an L-shaped or willow-leaf-shaped prosthesis made of solid silastic material is provided with a long slot, and a sliver body corresponding to the long slot made of expanding polytetrafluoroethylene material is stuck in the long slot. The important nasal back part (the nose apex part) is made of the expanding polytetrafluoroethylene material which has excellent karyogamic performance with human body tissues. Thus, after the material is implanted into the human body, the human body autogenous histiocytes grow into the expanding polytetrafluoroethylene material. Thus, material repulsion, movement, ulceration, etc., are effectively prevented, and a light reflecting phenomenon is also prevented to enable a shaped face to be natural and vivid. A base of the composite nasal prosthesis is a silicone rubber body and has a certain hardness, the cutting process is simple, and the implantation is convenient. The composite nasal prosthesis can be prefabricated into a specific shape in manufacture to be in accordance with the requirements of clinical application. The present invention has the advantages of low cost and reasonable price, and thus, the present invention is in accordance with common people's endurance and can be easily accepted by most people.
Description
Technical field:
The invention belongs to the nose prosthesis that the facial plasty filling is used, particularly the improvement of nose prosthesis structure.
Background technology:
The nose prosthesis that facial plasty filling is at present used is made material, and what be widely used most is silastic product and expanded PTFE material product.By the nose prosthesis that silastic material is made, its structure is the L type.For silastic product, because its material is too stiff, thereby often natural perception is not ideal enough; And behind the silicone rubber nose prosthesis implant into body, with the mode of healing of tissue be fibers encapsulation, so As time goes on, nose prosthesis in human body, have produce move, the probability of ulceration; Some people can produce the reflection of light phenomenon in the bridge of the nose portion of nose prosthesis after implanting nose prosthesis, makes outward appearance seem very nature; Because human body cell can't be grown in the prosthese, so silastic prosthesis inserts the surface tension behind the human body for a long time, can cause the chronic rejection of prosthese again.The nose prosthesis that expanded PTFE is made, because the quality softness of material own is difficult for cutting, molding, its shape can only be bulk, cuts when filling is implanted again.And so, operating time prolongs, and process is comparatively complicated, because material is too soft, puts into very difficulty in operation simultaneously, uses very inconvenient; And it costs an arm and a leg, and is difficult to promote.
Summary of the invention:
The present invention provides a kind of composite nose prosthesis of being made up of firm silicone rubber and two kinds of materials of expanded PTFE for solving the problem that prior art exists.Composite nose prosthesis is made for L type or Folium Salicis Babylonicae type by silicone rubber, has an elongated slot 2 in the bridge of the nose portion 1 of L type or Folium Salicis Babylonicae type, be bonded with in the elongated slot that expanded PTFE makes with the corresponding elongate body 3 of elongated slot.The present invention is in the most key bridge of the nose portion (comprising nose portion), adopted the expanded PTFE material splendid with the tissue blending, make the human body self histiocyte expanded PTFE material internal of growing into, thus after effectively having prevented material to implant rejection, move, the generation of phenomenon such as ulceration; Also prevented simultaneously, made the facial shape after the shaping more natural, true to nature the reflection of light phenomenon.This composite nose prosthesis, its pedestal is a firm silicone rubber, so certain rigidity is arranged, working angles is simple, implants also to be easy to, and can be prefabricated into specific shape when making, and makes it more to meet the needs of clinical practice.For the present invention, because its cost is lower, reasonable price meets common people's ability to bear, is accepted by most of people easily.
Specific embodiment:
Accompanying drawing 1 is a front view of the present invention.
Accompanying drawing 2 is side views of accompanying drawing 1.
1 bridge of the nose portion, 2 grooves, 3 elongate body (block).
Composite nose prosthesis is made for L-type by the firm silicone rubber material, in the bridge of the nose section of L-type 1 has an elongated slot 2, is bonded with corresponding with elongated slot that the expanded PTFE material makes in the elongated slot Elongate body 3.
Claims (2)
1, a kind of composite nose prosthesis is made for L type or Folium Salicis Babylonicae type by firm silicone rubber, it is characterized in that having a groove (2) in the bridge of the nose portion (1) of L type or Folium Salicis Babylonicae type, be bonded with in the groove that expanded PTFE makes with the corresponding block of groove (3).
2, according to the described composite nose prosthesis of claim 1, it is characterized in that groove (2) for microscler, be bonded with in the elongated slot that expanded PTFE makes with the corresponding elongate body of elongated slot (3).
