- 中手骨に装着される中手骨部材の先端に顆部を形成し、この顆部を基節骨に装着される基節骨部材に形成した関節面で回動可能に支持した人工指関節であり、関節面の中央から先端に径大の球状体を形成したポストを顆部内に形成した溝穴に突入させ、ポストと溝穴の関係を、基節骨部材が中手骨部材に対して伸展したときには、球状体が溝穴から挿入できて基節骨部材が中手骨部材に接続でき、かつ、基節骨部材が中手骨部材に対して左右に傾動でき、屈曲するに従って傾動が窮屈になるとともに、完全に屈曲したときには、傾動が規制され、かつ、球状体が溝穴から抜出不能になるようにしたことを特徴とする人工指関節。
- 球状体より下方のポストの両側に沿う溝穴の部分を添延部とし、この添延部を基節骨部材が伸展位から屈曲位に行くに従って漸次幅狭に設定するとともに、完全屈曲時には、ポストの幅とほぼ等しくした請求項1の人工指関節。
- 中手骨部材の顆部の上面に伸筋腱を収嵌する凹状溝を形成した請求項1又は2の人工指関節。
