Description
挿入部10の先端部11は、初期段階においては通常の内視鏡と同様の手順で組み立てられる。すなわち、対物カバーレンズ26と第1の凸レンズ36と枠部材24とが接着により固定されて一体化されたユニットを、先端部本体12の第1の円孔14に先端部本体12の先端部側から基端部側に嵌め込んで接着により固定する。
使用時後、想定外の処理が行なわれて内視鏡の挿入部10の先端部11の先端部本体12から照明レンズ32が外れても、照明レンズ32が係止部62によって係止された状態を維持することができる。このため、光学部材32が挿入部10の先端部11の先端部本体12から脱落することを防止することができる。さらに、光学部材32が先端部本体12に組み付けられた状態で係止部62を形成するので、組立作業を効率的に行なうことができる。
(付記項1) 挿入部先端に設けられた先端部本体に、対物光学系あるいは照明光学系の少なくとも一方を配設した内視鏡において、
光学窓部材を内挿する先端部材に設けられた孔との境界に係止部を設けたことを特徴とする内視鏡。
Claims (2)
- 管腔内に挿入される細長い挿入部の先端部に配設された硬質の先端部本体に光学部材が装着される装着孔を有する内視鏡であって、
前記装着孔と、その装着孔に装着される前記光学部材との境界の少なくとも一部に、前記先端部本体に対して前記光学部材を機械的に拘束する拘束部を設け、
前記拘束部は、前記光学部材の装着孔の開口部の周縁から開口部の内方側に延出させて前記光学部材を固定する固定部を有し、
前記固定部は、前記光学部材の装着孔と前記光学部材との間の少なくとも一部を溶着して固定した溶着部を有し、
前記溶着部は、前記先端部本体の一部を溶融させた溶湯を、溶融された前記先端部本体の近傍の前記光学部材の周縁部の一部に延出させた状態で硬化させて固定した延出部を有することを特徴とする内視鏡。 - 管腔内に挿入される細長い挿入部の先端部に配設された硬質の先端部本体に光学部材が装着される装着孔を有する内視鏡であって、
前記装着孔と、その装着孔に装着される前記光学部材との境界の少なくとも一部に、前記先端部本体に対して前記光学部材を機械的に拘束する拘束部を設け、
前記拘束部は、
軸部とこの軸部の一端部に設けられ、前記軸部の外径よりも大径の頭部とを有する係止ピンと、
前記光学部材の装着孔の開口部の周縁に、前記係止ピンの軸部が挿入され、前記装着孔よりも小径の少なくとも1つの小孔と
を備え、前記係止ピンの頭部の一部で前記光学部材の周縁部を前記装着孔に係止する係止部を有することを特徴とする内視鏡。
