Abstract
Description
ゴブレット状内挿体2の先端には環状ブレード3が取り付けられ、ゴブレット状内挿体2が外殻体1内の奥まで後退した位置では、環状ブレード3はゴブレット状外殻体1の先端部4から突出せずに外殻体1内に収納されている。環状ブレード3と反対側のゴブレット状内挿体2の端部には、ロッド6が摺動可能に挿入される中心軸穴5を備えた第2の中空管軸部2aが設けられる。ロッド6は、前記中心軸穴5の摺動部と反対側の端部7にアンビル8が取り付けられるよう構成される。
図示したステイプラーのヘッド部分において、ゴブレット状外殻体1の中空管軸部1aは公知の方法でハンドル(不図示)に接続される。ステイプラーのハンドルには公知のロッド引っ張り手段(不図示)が設けられ、該手段によってロッド6を第2管軸部2aの中心軸穴5へと徐々に引き込むと、アンビル8と環状ブレード3が徐々に接近する。こうしてステイプラーのヘッド部分を閉位置にして粘膜切除をする。
ステイプラーのハンドルに設けた当業者には公知のブレード移動手段(不図示)によって環状ブレード3を前進させて粘膜を切除する。ゴブレット状外殻体2の端部4には、金属製ステイプル等の縫合手段を収納する収納部4aを設けてもよい。図2では、ステイプラーのヘッド部分が開位置で、フランジ10a、10bを備えた中空筒状の導入部材10を通して管状臓器9の中に挿入されている。
Claims (8)
- ヘッド部分に、ロッド(6)が摺動可能に挿入される中心軸穴(5)を備えたゴブレット状外殻と該外殻に摺動自在に嵌挿されるゴブレット状内挿体からなるゴブレット状嵌合体(1、2)を少なくとも備える粘膜切除術用ステイプラーにおいて、
前記ロッド(6)の外周面には、1以上のリング状溝(11)が軸方向に的確に間隔を規定して設けられ、前記溝(11)は前記ロッド(6)の周囲に巾着縫合を施した部分の粘膜(9a)が収納されるよう構成したことを特徴とする粘膜切除術用ステイプラー。 - 前記ロッド(6)の溝(11)の深さは0.5mmから3mmの間としたことを特徴とする請求項1記載のステイプラー。
- 前記ロッド(6)の溝(11)の深さを約1mm(1±0.1mm)としたことを特徴とする請求項2記載のステイプラー。
- 前記ロッド(6)の断面は円形であることを特徴とする請求項1〜3のいずれか1項に記載のステイプラー。
- 前記ロッド(6)の各リング状溝(11)は、ロッド(6)の外周面よりも直径が短い円軸状溝部(12)と、該円軸状溝部(12)とロッド(6)外周面とを繋ぐように傾斜する傾斜面(13)により形成されることを特徴とする請求項1〜4のいずれか1項に記載のステイプラー。
- 前記傾斜面(13)において、前記円軸状溝部(12)側と前記ロッド(6)外周面側の高低差が1mmであることを特徴とする請求項5に記載のステイプラー。
- ゴブレット状外殻体(1)の中により小さい背高サイズのゴブレット状内挿体(2)が同軸上に摺動可能に設けられ、
該ゴブレット状内挿体(2)は、先端部には環状ブレード(3)が取り付けられ、管軸部(2a)には前記ロッド(6)が摺動可能に挿入される中心軸穴(5)が備えられることを特徴とする請求項1〜6のいずれか1項に記載のステイプラー。 - 前記ロッド(6)の端部(7)にアンビル(8、8’)が固定して取り付けられることを特徴とする請求項1〜7のいずれか1項に記載のステイプラー。
