The conventional total contact suction AK prosthesis presents several disadvantages, such as difficulty in wearing the socket in a sitting position, difficulty in obtaining a favourable disposition of the stump soft tissues in the socket and difficulty in avoiding stump perspiration problems. In an attempt to solve these disadvantages, a new AK prosthesis with a thermoplastic double socket was developed at the Tokyo Metropolitan Rehabilitation Center for the Physically and Mentally Handicapped. The double socket is composed of an external socket attached to the lower parts and a detachable internal socket, and appears to solve all the disadvantages of the conventional prosthesis. This prosthesis is called the TC prosthesis, and abbreviation for the Tokyo Metropolitan Rehabilitation Center. The first model of this prosthesis, (TC-1) has a metal valve. A new rubber sheet valve was developed to solve several disadvantages of the metal valve in the TC-2 prosthesis. Since November 1978 the TC-1 has been fitted to 295 AK amputees, including 9 bilateral AK amputees, and since March 1980, 145 AK amputees have received the TC-2, including 6 bilateral amputees. Satisfactory results have been obtained with both prostheses.
传统的全接触吸引式大腿假肢存在一些缺点，比如坐姿穿戴接受腔困难、难以在接受腔内使残肢软组织达到良好的分布状态以及难以避免残肢出汗问题。为了解决这些缺点，东京都身心障碍者康复中心研发了一种带有热塑性双接受腔的新型大腿假肢。双接受腔由连接下肢部分的外部接受腔和一个可拆换的内部接受腔组成，似乎解决了传统假肢的所有缺点。这种假肢被称为TC假肢，是东京都康复中心的缩写。该假肢的第一个型号（TC - 1）有一个金属瓣膜。为了解决TC - 2假肢中金属瓣膜的几个缺点，研发了一种新的橡胶片瓣膜。自1978年11月以来，已有295名大腿截肢者安装了TC - 1，其中包括9名双侧大腿截肢者；自1980年3月以来，有145名大腿截肢者接受了TC - 2，其中包括6名双侧截肢者。两种假肢都取得了令人满意的效果。
