Description
この出願は、この出願に参照によって取り込まれる“二極性内部人工装具用のつなぎ留められたヘッド”というタイトルが付けられた2001年1月25日に提出された仮出願NO.60/264,153に対して優先権を主張する。
本発明は、一般的には、人工装具インプラント(implants)(人工装具の関節形成面が互いに分離することを防止するための装置含む)に関する方法、システム、装置に向けられる。より具体的には、インプラントステムヘッド(implant stem head)が人工装具構成部品から脱臼されるのを防止するための装置に向けられる。
股関節、肩関節、膝関節を含む人工インプラントは、整形外科手術で広く使われている。股関節の人工装具は、一般的である。人間の股関節は機械的にボールソケットジョイントとして働き、大腿骨のボール形のヘッドが、骨盤のソケット型の寛骨臼の中に配置される。種々の変性疾患と損傷は、合成材料を用いた股関節の全部又は一部の交換を必要とするかも知れない。人工装具構成部品は、一般に金属、セラミックス、プラスチックのいずれかから作られる。
下で述べられるのは、本発明によるシステムと方法の簡単な要約である。本発明は、ここで具現化され、広く説明されるように、本発明の目的に従って前述の問題に取り組み、利益と利点を提供する。この発明の1つの実施形態による人工装具は、現在の拘束式人工装具よりも拡大された動作範囲を有する拘束式人工装具を提供する。この発明の1つの実施形態によると、拘束式人工装具は、大腿骨構成部品の脱臼を防止する。この発明の人工装具は、人間と動物と共に使用されてもよく、従来の股関節人工装具(股関節全体の関節形成術に使用される内部人工装具と人工装具を含む。)と共に使用されてもよい。
この発明の1つの実施形態による収容システムの他の特徴は、拡大された動作範囲を提供する拘束式人工装具構成部品である。
この発明の1つの実施形態による収容システムのさらに別の特徴は、製造費用が高くなく、少ない数の部品を備えることである。
この発明の1つの実施形態による収容システムのさらに別の特徴は、組み立てが容易で、組み立てのために追加の器具を必要としない収容システムである。
この発明による方法、システム、装置は、従来の拘束式人工装具よりも拡大された動作範囲を確保するとともに人工装具の関節形成面が互いに分離することを防止するための収容システムを提供しようとする。この発明による収容システムの1つの実施形態は、拡大された動作範囲を提供するとともに大腿骨構成部品のインプラントステムヘッドを拘束するための股関節の人工装具構成部品を提供しようとする。一般的に、この発明の1つの実施形態による収容システムは、インプラントステムヘッドを受け入れるための空洞と開口とを有するインプラント構造部材を備える。開口は、リップとリップの一部に沿ったウェブとを備える。収容システムは、ウェブの形状に対応した形状をした協働面を有するインプラントステムヘッドも備える。インプラントステムヘッドは、ヘッドの協働面がウェブと揃えられるときにのみインプラント構造部材に挿入され、取り外されるように構成されている。
前述したものは、この発明の実施形態を図解,描写、説明する目的で提供される。これらの実施形態に対する修正と適用は、当業者にとって明らかであり、この発明と次のクレームの範囲と精神を逸脱せずになされることができる。
