〔発明の分野〕
本発明は全体的に外科手術器具用の支持体、および外科手術器具のエンドエフェクタ組立体に取り外し可能に取り付けられるよう構成された支持体に関する。
(Field of the Invention)
The present invention relates generally to a support for a surgical instrument and a support configured to be removably attached to an end effector assembly of a surgical instrument.

〔関連技術〕
外科手術用ステープラ等の外科手術器具は、外科手術の工程において組織にステープルを配備するよう構成できる。種々の実施形態において、外科手術用ステープラは、その外科手術用ステープラの先端部に位置されるように構成されたエンドエフェクタを含むことができる。このエンドエフェクタは、カニューレやトロカールの内部に位置されて、少なくとも一部分をカニューレやトロカールの内部にスライドさせるように構成されることができ、また、患者の体壁に位置して、外科医が手術部位を治療するのに使用することができる。種々の実施形態において、エンドエフェクタはステープルカートリッジを有する第一ジョー部材を備えることができ、加えて、アンビルを有する第二ジョー部材を備えることができる。第一ジョー部材と第二ジョー部材を互いに近位側に移動させ、それらの間に組織層を挟んで圧縮力を加えるよう構成できる。少なくとも一つの実施形態では、ステープルカートリッジはその内部に取り出し可能にステープルを収納でき、アンビルはステープルがステープルカートリッジから配備されると、ステープルを変形させることができる。
[Related technologies]
Surgical instruments such as surgical staplers can be configured to deploy staples to tissue during the surgical process. In various embodiments, the surgical stapler can include an end effector configured to be located at the distal end of the surgical stapler. The end effector is positioned within the cannula or trocar and can be configured to slide at least a portion of the cannula or trocar into the cannula or trocar. Can be used to treat. In various embodiments, the end effector can comprise a first jaw member having a staple cartridge and, in addition, a second jaw member having an anvil. The first jaw member and the second jaw member can be moved proximally relative to each other, and a compressive force can be applied with a tissue layer interposed therebetween. In at least one embodiment, the staple cartridge can removably receive staples therein and the anvil can deform the staples when the staples are deployed from the staple cartridge.

場合によって、組織層は比較的薄かったり、多量の水分を含有していたり、および/または厚みが不均一なことがあり、ステープルが組織内で上手く留まらない原因となる。この問題を改善するために、支持体の要素を利用して組織を支持し、組織を挟んでステープル留めすることができる。少なくとも一つの実施形態では、第一ジョー部材および第二ジョー部材が手術部位に挿入される前に、支持体の要素を第一ジョー部材および第二ジョー部材に取り外し可能に取り付けることができる。種々の実施形態において、支持体の要素は、支持体の表面領域上にアンビルによって加えられる圧縮力を分散し、組織内で組織のより均一な圧縮形状を形成できる。少なくとも一つの実施形態では、組織の均一な圧縮形状によって、組織内で適切なステープル留めが行われる可能性が高くなる。  In some cases, the tissue layer may be relatively thin, contain a large amount of moisture, and / or be non-uniform in thickness, causing staples to not stay well in the tissue. To remedy this problem, the elements of the support can be used to support the tissue and staple it across the tissue. In at least one embodiment, the elements of the support can be removably attached to the first jaw member and the second jaw member before the first jaw member and the second jaw member are inserted into the surgical site. In various embodiments, the elements of the support can distribute the compressive force applied by the anvil over the surface area of the support to form a more uniform compressed shape of the tissue within the tissue. In at least one embodiment, the uniform compressed shape of the tissue increases the likelihood of proper stapling within the tissue.

種々の実施形態において、支持体の要素をエンドエフェクタのジョー部材に取り付けることは外科医にとって困難となりうる。少なくとも一つの実施形態では、支持体の要素を一方のジョー部材に取り付けるのに、支持体の要素を取り外し可能に保持するよう構成された接着剤を使用してもよい。このような実施形態では、接着剤が即座に支持体をジョー部材に接着させる可能性があるため、外科医は支持体の要素とジョー部材を整合させるのに細心の注意を払わねばならない。この場合、支持体の要素をジョー部材から取り外して新たな支持体の要素に取り替える必要がある。結果として、外科医は、支持体の要素をエンドエフェクタのジョー部材に位置して整合させるために貴重な時間を割かねばならない。これらに対する改良が必要である。  In various embodiments, attaching the support element to the end effector jaw member can be difficult for the surgeon. In at least one embodiment, an adhesive configured to removably hold the support element may be used to attach the support element to one jaw member. In such an embodiment, the surgeon must take great care in aligning the elements of the support and the jaw members as the adhesive can quickly bond the support to the jaw members. In this case, it is necessary to remove the support element from the jaw member and replace it with a new support element. As a result, the surgeon must spend valuable time positioning and aligning the support elements with the end effector jaw members. Improvements to these are needed.

〔発明の概要〕
本発明の少なくとも一つの形態によれば、支持体の要素および/または手術器具のエンドエフェクタは、外科医またはその他の医師が、支持体の要素をエンドエフェクタに適切に整合させて取り付けることを補助する特徴を備えることができる。少なくとも一つの実施形態では、支持体の要素は、支持体の要素から延びる少なくとも一つの部材を含むことができ、この部材はステープルカートリッジ内に画定されたステープルキャビティおよび/またはアンビル内に画定されたアンビルポケットのうち一方と係合するよう構成できる。このような実施形態の少なくとも一つでは、例えば、部材はステープルキャビティおよび/またはアンビルポケット内に摩擦嵌合および/または圧入されて、支持体の要素をステープルカートリッジおよびアンビルのうち一方に取り外し可能に保持することができる。種々の実施形態において、切欠部またはスロットをステープルカートリッジおよび/またはアンビルのうち一方に画定し、切欠部は支持体の要素の一部を受容して支持体の要素を取り外し可能に保持するよう構成できる。少なくとも一つの実施形態では、支持体の要素は、支持体の要素から延びる突起を含むことができ、この突起は、ステープルカートリッジおよびアンビルのうち少なくとも一方に設けられた切開部材用経路に取り外し可能に係合するよう構成できる。このような実施形態においては、突起は例えば圧入、摩擦嵌合、および/または上記経路に係合することができる。
