Abstract
Description
本願は、2013年3月28日に、米国に仮出願された米国特許出願第61/806,114号に基づき優先権を主張し、その内容をここに援用する。
例えば、特許文献1には、内視鏡のチャンネルの内面を保護する目的で、処置部を収納する収納部を設けた医療器具が記載されている。
本発明の第1の態様の医療器具は、体内に挿入可能な挿入部と、前記挿入部に連結された駆動機構と、を備え、前記挿入部は、処置対象部位に対して処置を行う処置部と、前記処置部を支持し前記処置部の向きを変更可能な関節部と、前記関節部に設けられ前記処置部を内部に収納可能な収納部と、前記関節部に接続され前記処置部の向きを変更するための駆動力を前記関節部に伝達する駆動力伝達部と、を有し、前記駆動機構は、前記駆動力伝達部に接続され前記駆動力を発生させる駆動力発生部を有し、前記駆動力発生部が前記駆動力伝達部を介して前記関節部に伝達する前記駆動力によって前記処置部が前記収納部に対して出入りする。
本発明の医療器具(medical device)の実施形態について、図1から図6を参照して説明する。
図1は、本発明の第1実施形態の医療器具を示す模式図である。図2は、同医療器具が内視鏡に取り付けられた状態を示す模式図である。図3は、同医療器具の先端部分を拡大して示す模式図であり、同医療器具の平面図である。図4は、同医療器具の先端部分を拡大して示す模式図であり、同医療器具の側面図である。図5は、図4のA-A線に沿った断面図である。図6は、同医療器具の先端部分を拡大して示す模式図であり、同医療器具の平面図である。
図1に示すように、医療器具1は、体内に挿入可能な挿入部2と、挿入部2に連結された駆動機構30とを備える。
切開電極4は、棒状の軸部6と、軸部6の先端側に設けられたフック部5とを有する。軸部6及びフック部5は導電性を有する金属線からなる。切開電極4となる金属線は、軸部6とフック部5との境界部分において折り曲げられた形状を有する。軸部6には、金属線の外面を被覆する絶縁皮膜が設けられていてもよい。切開電極4のフック部5は、たとえば丸型などであってもよい。切開電極4は、フック部5を有していなくてもよい。
支持部12は、回動軸11に連結された連結部13と、可撓管部20に固定された固定部16と、連結部13と固定部16との間に配された収納部18とを備える。
医療器具1は、例えば図2に示す内視鏡100等のマニピュレータにおいて、チャンネル101内に挿通される。チャンネル101は、鉗子及びその他の器具を処置対象部位まで案内するために設けられている。チャンネル101への挿入時には、処置部3が収納部18内へと移動するように第一ワイヤ24と第二ワイヤ25とのうちの一方(本実施形態では第二ワイヤ25)を駆動力発生部32により牽引する。本実施形態では、駆動力発生部32の第二アクチュエータ34が第二ワイヤ25を基端側へと牽引し、第一アクチュエータ33の駆動力が解除されて第一ワイヤ24をその中心線方向(挿入部2の長手軸方向)へ自在に進退させる。これにより、処置部3である切開電極4は収納部18内に収納される(図6参照)。処置部3が収納部18内に収納されている状態では、処置部3が収納部18の外に出ている状態と比較して、先端と基端とを結ぶ直線方向における処置部3の長さが短い(図3及び図6参照)。このため、チャンネル101が湾曲した状態である場合に、処置部3がチャンネル101の内面に干渉しにくく、また処置部3がチャンネル101の内面を傷つけにくい。

図12に示すように、スイッチング機構40は、切開電極4が収納部18内に位置しているときには、柱状端子43の突端部43aが絶縁領域41Bに位置することにより、給電ケーブル26と切開電極4と通電を遮断している。また、図7に示すように、スイッチング機構40は、切開電極4が収納部18外に位置しているときには、柱状端子43の突端部43aが導通領域41Aにおいてバネ接点の平坦部42bに接することにより、給電ケーブル26と切開電極4とを導通させる。
