【発明の属する技術分野】 BACKGROUND OF THE INVENTION
本発明は、外科手術に用いられる、人体の生体組織の縫合を行う自動縫合器等の外科用器具のハンドル構造に関する。 The present invention is used in surgery, to handle structure of the surgical instrument of stapler or the like for suturing of human body tissue.
【0002】 [0002]
【従来の技術】 BACKGROUND OF THE INVENTION
近年の医療技術の発展に伴って、外科用器具自体もまた非常に複雑化してきている。 With the development in recent years of medical technology, itself has also been very complicated surgical instruments. これら外科用器具の複雑化が進行するのと同時に、操作方法も多種多様な複雑化したものがあり、例えば、その自動縫合器もその1つに該当する。 At the same time as the complexity of these surgical instruments progresses, while others operating method was also a wide variety of complex, for example, it is the stapler corresponding to one of them. このような自動縫合器では、最終目的である縫合を行うために、大別して、組織の適切な位置決め・把持(クランプとも言う)を行う第1の作動と、組織の切除及び縫合(ファイヤとも言う)を行う第2の作動の2つの作動が存在する。 In such a stapler, in order to perform the final an object sutures, roughly, also referred to first and actuating take appropriate positioning and gripping of tissue (also referred to as clamp), and excision and suture (fire organizations ) two operation of the second operating present to perform.
【0003】 [0003]
このような2つの作動に対応するために、第1トリガと、第2トリガとを備えるハンドルが知られている(例えば、特許文献1。)。 To cope with such a two actuation, a first trigger, a handle and a second trigger has been known (for example, Patent Document 1.). この特許文献1のハンドル構造では、第1トリガが、ハンドグリップから間隔の空いた未作動の第1トリガ位置から、ハンドグリップに隣接する完全に作動した第1トリガ位置へと反時計回りに旋回可能になっており、第2トリガが、第1トリガ位置から間隔の空いた未作動の第2トリガ位置から、第1トリガに隣接する完全に作動した第2トリガ位置へと反時計回りに旋回可能となっており、第1トリガが、第2トリガとハンドグリップとの間に位置している。 The handle structure of Patent Document 1, the turning first trigger, the first trigger position of the unactuated vacated from the hand grip spaced, and counterclockwise to first trigger position fully actuated adjacent the handgrip have become available, the second trigger, pivoting from the second trigger position in the unactuated that spaced from the first trigger position, a counterclockwise to a second trigger position fully actuated adjacent to the first trigger has become possible, the first trigger is positioned between the second trigger and the hand grip.
【0004】 [0004]
そして、ハンドルよりも先端部にあるエンドエフェクターと第1トリガとは、第1伝導アッセンブリーによってつながれ、エンドエフェクターと第2トリガとは、第2伝導アッセンブリーによってつながれている。 The end effector and the first trigger at the tip portion than the handle, connected by a first conductive assembly, the end effector and the second trigger is connected by a second conductive assembly. 第1トリガを引くことにより、第1伝動アッセンブリーが基端方向へと移動して、第1の作動である組織の適切な位置決めが行われる。 By pulling the first trigger, first transmission assembly moves to the proximal direction, proper positioning of the tissue first is operation is performed. また、第2トリガを引くことにより、第2伝導アッセンブリーが先端方向へと移動して、第2の作動である組織の切除及び縫合が行われる。 Further, by pulling the second trigger, the second conductive assembly is moved to the distal direction, excision and suturing of tissue, which is the second operation is performed.
【0005】 [0005]
ところで、この作動の手順は絶対的なものであり、第1の作動の完了する前、または、第1の作動より前に第2の作動が行われることがないように、そのような誤作動を防ぐための手段が必要となる。 Incidentally, steps in this operation are absolute, before completing the first operation, or, as the second actuation is not performed prior to the first actuation, such malfunction It is required means for preventing. このため、特許文献1において、第1トリガが未作動第1トリガに位置するとき、第2トリガは第2伝導アッセンブリーによって反時計回りの旋回が阻止されている。 Therefore, in Patent Document 1, when the first trigger is positioned in the unactuated first trigger, the second trigger counterclockwise turning is blocked by the second conduction assembly. その一方で、第1トリガが未作動第1トリガ位置からハンドグリップに向かって旋回するときに、第2伝導アッセンブリーは、第2トリガの旋回ができるように先端方向へと移動する。 On the other hand, when the first trigger is pivoted toward the hand grip from the unactuated first trigger position, the second conductive assembly is moved to the distal direction to allow pivoting of the second trigger. こうして、第1トリガを引くまでは、第2トリガを引くことができないが、第1トリガを引いて初めて、第2トリガを引くことができるようになっている。 In this way, up to draw the first trigger, but it is not possible to draw a second trigger, for the first time by subtracting the first trigger, so that it is possible to draw a second trigger.
【0006】 [0006]
第1の作動である組織の位置決めを適切に行うことは非常に重要であり、間違った部位で、第2の作動である組織の切除及び縫合をすることがないように、また、不完全な縫合による組織のダメージが発生することがないように、慎重に正確な位置で組織の把持を行う必要がある。 Be positioned in the tissue first is operating properly is very important, at the wrong site, so as not to resection and suturing of tissue is a second operation, also, incomplete as tissue damage due to the suture is not generated, it is necessary to grasp the tissue in carefully accurate position. そのため、この第1の作動は、しばしば、やり直しを必要とし、そのために、第1トリガは、作動中に、未作動第1トリガ位置へと戻ることができるようになっていなければならない。 Therefore, the first operation, often requiring rework, because the first trigger, during operation, must now be able to return to the unactuated first trigger position.
【0007】 [0007]
その一方で、第1の作動が適正に完了した後、第2の作動が開始されたならば、組織の把持解除といった誤作動が行われないようにしなければならない。 On the other hand, after the first operation is completed properly, if the second operation is started, malfunction such as grasping release of tissue must be not performed.
