北京航空材料研究所与鞍山铁东区医院于1993年3月共同承担了研制“形状记忆合金妇科宫内节育器”的任务,旨在研制出性能优越的节育器.目前妇科宫内节育器虽多达数十种,但因材料、形状及功能的不完善,容易造成某些并发症,如脱落、带器妊娠和腰腹痛等,给一些妇女带来了痛苦.现该所利用TiNi记忆合金的特性,改进现有的形状设计,研制出适于人体温度(35～37℃)使用的节育器,提高了使用效果并减少了并发症.它是一种具有多功能的新型节育器,即形状记忆合金弓环形堵塞性宫内节育器.这种节育器手术简单,可靠性好.现已获国家实用新型专利.
Beijing Institute of Aeronautical Materials and Anshan Tiedong District Hospital in March 1993 jointly undertaken the development of “shape memory alloy gynecological intrauterine device,” the task, to develop a superior performance of the IUD.There are many gynecological IUD Dozens of kinds, but due to imperfections in material, shape and function, likely to cause some complications, such as shedding, pregnancy and abdominal pain with abdominal pain, etc., to some women have caused pain.Today, the use of TiNi memory alloy Characteristics, improve the existing shape design, developed for the body temperature (35 ~ 37 ℃) use of the IUD, to improve the use of effects and reduce complications. It is a versatile new IUD, namely the shape Memory alloy bow ring blockage intrauterine device. This IUD operation is simple, good reliability. Now won the national utility model patents.
