Description
本発明は手術用器具に関し、より具体的には内視鏡を用いた手術において好適な手術用器具に関する。 The present invention relates to a surgical instrument, and more specifically to a surgical instrument suitable for surgery using an endoscope.
内視鏡下手術とは、体表部に５〜１０ｍｍ程度の創を数箇所設け、そこにφ２〜１６ｍｍのトロカールとよばれる筒を挿入し、そこから内視鏡や長鉗子と呼ばれるφ３〜１０ｍｍ程度の手術器具を挿入し行なう手術である。この手術は低侵襲性という患者への大きなメリットがある反面、手術器具の形状・操作性に制限があり、術式の難易度は開腹手術に比して高いため、より高機能なエンドエフェクタを有するものが望まれている。 Endoscopic surgery means that several wounds of about 5 to 10 mm are provided on the surface of the body, and a tube called a trocar having a diameter of 2 to 16 mm is inserted therein, from which a diameter of 3 to 3 called an endoscope or a long forceps is inserted. This is an operation performed by inserting a surgical instrument of about 10 mm. Although this operation has a great merit for patients with minimal invasiveness, the shape and operability of surgical instruments are limited, and the difficulty of surgical procedures is higher than that of open surgery. What you have is desired.
内視鏡等を挿入するために設けられる創のサイズの制限に関する問題を緩和するエンドエフェクタとして、例えばリトラクタ（圧排器具）や、腹腔内組立式ロボットハンドがある。 As an end effector that alleviates the problem related to the limitation on the size of a wound provided for inserting an endoscope or the like, there are, for example, a retractor (retraction device) and an intra-abdominal assembly robot hand.
公知のリトラクタを備えた手術用器具として、例えば下記特許文献１に、人の手のひらと同程度（１５０ｍｍ×７０ｍｍ）まで展開できるものが開示されている。 As a surgical instrument equipped with a known retractor, for example, the following Patent Document 1 discloses an instrument that can be developed to the same extent as a human palm (150 mm × 70 mm).
また、下記非特許文献１には、複数のパーツに分解して体内へ導入した後に腹腔内で組み立てる組立式タバコ縫合器を有する手術器具が開示されている。 Non-Patent Document 1 below discloses a surgical instrument having an assembled tobacco suturing device that is assembled into the abdominal cavity after being disassembled into a plurality of parts and introduced into the body.
更に、下記特許文献２には、３指を有するロボットハンドを複数のパーツに分解して体内に導入した後に腹腔内で組み立てるロボットハンドを有する手術器具が開示されている。 Furthermore, Patent Document 2 below discloses a surgical instrument having a robot hand that is assembled in the abdominal cavity after a robot hand having three fingers is disassembled into a plurality of parts and introduced into the body.
しかしながら、上記特許文献１に記載の技術は、シンプルな構造であるため、大きさや形状が異なるそれぞれの臓器に適した圧排や把持・挙上などの操作が困難であるといった課題がある。また、トロカールの径内に収まるように重ねられた複数の板状の部品により作業面が構成されるため、強度の確保が難しいといった課題がある。 However, since the technique described in Patent Document 1 has a simple structure, there is a problem that operations such as exclusion, grasping and raising suitable for each organ having different sizes and shapes are difficult. In addition, since the work surface is composed of a plurality of plate-like components stacked so as to be within the diameter of the trocar, there is a problem that it is difficult to ensure strength.
また、上記非特許文献１のように、複数のパーツに分解して体内へ導入した後に腹腔内で組み立てる技術は、体内においてパーツが脱落・遺失してしまう危険性がある。また、構成によっては複数の創を設けてそのそれぞれからパーツを導入しなければならない場合があり、一つの手術器具のために２つ以上の開創を要求してしまうため、低非侵襲性の観点から課題を残す。 In addition, as in Non-Patent Document 1, the technique of assembling within the abdominal cavity after disassembling into a plurality of parts and introducing them into the body has a risk that the parts may fall off or be lost in the body. Also, depending on the configuration, it may be necessary to provide multiple wounds and introduce parts from each of them, which requires two or more wounds for a single surgical instrument, so it has a low non-invasive viewpoint. Leave a challenge from.
また、上記特許文献２の鉗子は把持部が１つであり、大きさや構造が異なる臓器で使用するときに、術具を交換する作業が必要になる。また、鉗子を使用するためには、体内に挿入後器具を鉗子の形態に変化させる作業が必要であり、体内に挿入後すぐに使用したいといった要求に答えるためには検討すべき課題が残る。 Further, the forceps of the above-mentioned Patent Document 2 has one gripping part, and it is necessary to replace the surgical tool when used with organs having different sizes and structures. Moreover, in order to use forceps, the operation | work which changes an instrument after insertion in a body to a form of forceps is required, and the subject which should be examined remains in order to respond to the request | requirement of using immediately after insertion in a body.
そこで、本発明は上記課題を解決し、非侵襲性を確保しつつ、操作性・強度に優れ、パーツ脱落のおそれも少なく、器具の形態変化の手順がより簡単な手術用器具を提供することを目的とする。 Accordingly, the present invention provides a surgical instrument that solves the above-mentioned problems, is excellent in operability and strength, is less likely to drop off, and has a simpler procedure for changing the form of the instrument while ensuring noninvasiveness. With the goal.
上記課題を解決する一の手段に係る手術用器具は、主軸部と、重ねあわされて開閉可能な挟み部材を有する第一の把持部と、主軸部に対し第一の把持部を折り曲げる折曲部と、折曲部の両側に備えられる、一対の挟み部材と、を有する第二の把持部と、を備える。 A surgical instrument according to one means for solving the above problems includes a main shaft portion, a first grip portion having a sandwiching member that is overlapped and opened and closed, and a bending that bends the first grip portion with respect to the main shaft portion. And a second grip part having a pair of pinching members provided on both sides of the bent part.
以上本発明により、非侵襲性を確保しつつ、操作性・強度に優れ、パーツ脱落のおそれも少なく、器具の形態変化の手順がより簡単な手術用器具を提供することができる。 As described above, according to the present invention, it is possible to provide a surgical instrument that ensures non-invasiveness, is excellent in operability and strength, is less likely to drop off parts, and has a simpler procedure for changing the form of the instrument.
以下、本発明を実施するための最良の形態について、図面を用いて詳細に説明する。ただし、本発明は多くの異なる形態による実施が可能であって、以下に示す実施形態、実施例の例示にのみ限定されるわけではない。 Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

In this main shaft portion, the main shaft portion is the direction in which the main shaft portion 2 extends (stretching direction). Further, inside the main shaft portion 2, a wire for opening and closing the first gripping portion 3, a link mechanism and a wire for folding the first gripping portion 3 at the bending portion 41, and a second gripping portion are opened and closed. It is preferable that a drive member such as a link mechanism is accommodated. In addition, although it does not necessarily limit as a material of the main-shaft part 2, it is a preferable example that it is a metal or resin.
また本実施形態において、第一の把持部３は、本手術用器具の先端部分に設けられており、手術の際、様々な物を把持するために用いられる部材である。本実施形態において第一の把持部３は、上述のとおり開閉する必要から、開閉可能な挟み部材３１が重ねあわされており、重ねあわされた状態では一方向（延伸方向）に延びた棒状である。第一の把持部３の材質としては特に限定されるわけではないが、金属又は樹脂であることは好ましい一例である。 Moreover, in this embodiment, the 1st holding part 3 is provided in the front-end | tip part of this surgical instrument, and is a member used in order to hold | grip various things in the case of a surgery. In the present embodiment, since the first gripping portion 3 needs to be opened and closed as described above, the pinching member 31 that can be opened and closed is overlapped, and in the overlapped state, the first gripping portion 3 has a rod shape extending in one direction (extension direction). is there. Although it does not necessarily limit as a material of the 1st holding | grip part 3, It is a preferable example that it is a metal or resin.
第一の把持部３における挟み部材３１は、一対で構成されており、それぞれが、物を挟むための接続部材と、挟み部材３１同士を開閉可能な状態で保持するための軸部材３１２と、を有し、それぞれの軸部材３１２は同軸に組み合わされて構成されていることが好ましい。本実施形態では、開閉が可能である限りにおいて限定されないが、主軸部２からワイヤを伸ばしてこの軸部材３１２に巻きつける一方、このワイヤを引っ張ることで軸部材３１２を回転させ、結果挟み部材３１の開閉を行わせる構成としておくことが好ましい。この場合のイメージを図２に示しておく。本図は、第一の把持部３における挟み部材、接続部材、軸部材及びワイヤ以外の構成を省略し側面から見た場合の図である。なおこの場合、軸部材３１２のほか、ワイヤを巻きつけるためのガイド軸部材３１３を設けておくことで、一本のワイヤを巻きつけてワイヤを折り返して巻きつけるとともに、ワイヤの引く側を変えることで簡便に開閉を行わせることができる。なお、本図において、（Ａ）は閉じた状態の図を、（Ｂ）は開いた状態の図をそれぞれ示しておく。 The sandwiching member 31 in the first grip portion 3 is configured in a pair, each of which includes a connecting member for sandwiching an object, and a shaft member 312 for holding the sandwiching member 31 in an openable / closable state. Each shaft member 312 is preferably configured to be coaxially combined. In this embodiment, there is no limitation as long as it can be opened and closed. However, the wire is extended from the main shaft portion 2 and wound around the shaft member 312, while the shaft member 312 is rotated by pulling the wire, resulting in the pinching member 31. It is preferable to have a configuration that opens and closes. An image in this case is shown in FIG. This figure is a view of the first grip portion 3 when viewed from the side with the configuration other than the pinching member, connecting member, shaft member, and wire omitted. In this case, in addition to the shaft member 312, a guide shaft member 313 for winding the wire is provided, so that one wire is wound and the wire is folded and wound, and the wire drawing side is changed. Can be easily opened and closed. In this figure, (A) shows a closed state, and (B) shows an opened state.
また、第一の把持部３には、接続部材３１４が備えられており、接続部材３１４によって第二の把持部４と接続されている。 Further, the first grip portion 3 is provided with a connection member 314 and connected to the second grip portion 4 by the connection member 314.
また本実施形態において、第二の把持部４は、上記のとおり折曲部４１と、この折曲部４１の両側に備えられる一対の挟み部材４２を有している。 Moreover, in this embodiment, the 2nd holding part 4 has the bending part 41 and a pair of clamping member 42 with which both sides of this bending part 41 are provided as mentioned above.
本実施形態において、折曲部４１は、主軸部２に対し第一の把持部３、より詳細には、第一の把持部３及び第二の把持部４における一方の（第一の把持部側の）挟み部材４２を主軸部の軸方向に対して反対に（１８０度に）折り曲げることができるよう設けられるものである。本実施形態において折曲部４１の材質としては特に限定されるわけではないが、金属又は樹脂であることは好ましい一例である。 In the present embodiment, the bent portion 41 is the first grip portion 3 with respect to the main shaft portion 2, more specifically, one of the first grip portion 3 and the second grip portion 4 (the first grip portion). The sandwiching member 42 on the side is provided so that it can be bent oppositely (in 180 degrees) with respect to the axial direction of the main shaft portion. In the present embodiment, the material of the bent portion 41 is not particularly limited, but a metal or resin is a preferred example.
本実施形態において折曲部４１は、一辺の両角が丸くなっている四角形状をしており、その一対の折曲部材４１１が第二の把持部４における挟み部材４２を挟んで重ねあわされて構成されている。また、そのそれぞれにおいて、第一の軸４１１１、第二の軸４１１２の二つの軸が貫通して設けられており、隣接する挟み部材４２が回転可能となるよう挟み込まれて接続されている。なお、ここで第一の軸４１１１および第二の軸４１１２の２つの軸は回転する必要から平行となっている。また、折曲部４１において折曲面とは、第一の把持部が軸を中心に折り曲げられる際、第二の把持部５と第一の把持部３が回転する面をいい、具体的にはこの第一の軸及び第二の軸に対して垂直な面をいう。後述の記載からも明らかとなるが、本実施形態において折曲部４１は、折り曲げられた状態において、物を挟むための先端部分となる。図３に、折曲部４１によって折り曲げられる場合の概略図を示しておく。なお本図において、紙面と平行な面が折曲面である。なお本図において（Ａ）は直線の状態における概略図を、（Ｂ）は折り曲げた状態における概略図をそれぞれ示す。
In the present embodiment, the bent portion 41 has a quadrangular shape in which both corners are rounded, and the pair of bent members 411 are overlapped with the pinching member 42 in the second gripping portion 4 interposed therebetween. It is configured. Further, in each of them, two shafts of a first shaft 4111 and a second shaft 4112 are provided so as to pass through, and the adjacent sandwiching members 42 are sandwiched and connected so as to be rotatable. Here, the two axes of the first axis 4111 and the second axis 4112 are parallel because they need to rotate. Further, the bending surface in the bent portion 41 means a surface on which the second gripping portion 5 and the first gripping portion 3 rotate when the first gripping portion is bent around the axis. A plane perpendicular to the first axis and the second axis. As will be apparent from the description below, in the present embodiment, the bent portion 41 is a tip portion for sandwiching an object in the bent state. FIG. 3 shows a schematic diagram when the bent portion 41 is bent . In our present diagram as, paper parallel to the plane is bent surface. In this figure, (A) is a schematic diagram in a straight state, and (B) is a schematic diagram in a bent state .
また、本実施形態において、折曲部４１で折り曲げる手段としては、ワイヤ及びリンク機構を用いるは好ましい一例である。この例を図４に示しておく。本図は図３における折曲部材４１１を省略した図であって、一対の折曲部材４１１に挟まれた第二の把持部４における挟み部材４２を主として示している。本図で示すように、二つの挟み部材４２は、第一の軸４１１１、第二の軸４１１２、及び、折曲部材４１１（本図では図示省略）により接続されている。そして、本図の例では、先端側の挟み部材４２の一方の側部にワイヤの一端が固定され、そこから挟み部材４２の側部に沿って第一の軸４１１１、第二の軸４１１２の間で交差しつつ手元側（先端の反対側）の挟み部材の他方の側部に沿って配置される。そして、手元側の軸等によって折り返された後、再び挟み部材の一方の側部に沿って配置され、第一の軸４１１１、第二の軸４１１２の間で交差し、先端側の挟み部材４２の他方の側部に他端が固定されている。また、折曲部材４１１にはリンク機構が接続されており、リンク軸を介してして二つの棒状部材が接続されている。この構成を用いれば、例えば、リンク機構の棒状部材を引くと、折曲部材４１１が引っ張られ、回転を開始する。すると、一方のワイヤの張力により先端側の挟み部材４２も同様に回転を行う。そして、リンク機構を十分引くことで先端側の挟み部材４２を手元側の挟み部材４２に付けることが可能となる。 Moreover, in this embodiment, as a means to bend in the bending part 41, using a wire and a link mechanism is a preferable example. An example of this is shown in FIG. This figure is the figure which abbreviate | omitted the bending member 411 in FIG. 3, Comprising: The pinching member 42 in the 2nd holding part 4 pinched by a pair of bending member 411 is mainly shown. As shown in the drawing, the two sandwiching members 42 are connected by a first shaft 4111, a second shaft 4112, and a bending member 411 (not shown in the drawing). In the example of this figure, one end of the wire is fixed to one side portion of the pinching member 42 on the distal end side, and from there, the first shaft 4111 and the second shaft 4112 along the side portion of the pinching member 42. It is arranged along the other side of the sandwiching member on the hand side (opposite the tip) while intersecting. Then, after being folded back by the hand side shaft or the like, it is again arranged along one side of the pinching member, intersects between the first shaft 4111 and the second shaft 4112, and the pinching member 42 on the tip side. The other end is fixed to the other side. In addition, a link mechanism is connected to the bending member 411, and two rod-like members are connected via a link shaft. If this structure is used, for example, when the rod-shaped member of the link mechanism is pulled, the bending member 411 is pulled and starts rotating. Then, the pinching member 42 on the distal end side is similarly rotated by the tension of one of the wires. Then, by sufficiently pulling the link mechanism, it is possible to attach the front end side pinching member 42 to the hand side pinching member 42.
また本実施形態において、第二の把持部４には、手術の際、様々な物を把持するために用いられる部材としての挟み部材４２が折曲部の両側に一対設けられている。本実施形態において挟み部材４２の材質としては特に限定されるわけではないが、金属又は樹脂であることは好ましい一例である。 In the present embodiment, the second grasping portion 4 is provided with a pair of sandwiching members 42 on both sides of the bent portion as members used for grasping various objects during surgery. In the present embodiment, the material of the sandwiching member 42 is not particularly limited, but a metal or resin is a preferred example.
さらに、一対の挟み部材４２のそれぞれは、上記第一の把持部３の構造と同様、重ねあわされて一対に構成されており、そのそれぞれが、物を挟むための平板部分を有する平板部材４２１と、挟み部材４２同士を開閉可能な状態で保持するための軸部材４２２と、を有して構成されている。本実施形態では、開閉が可能である限りにおいて限定されないが、軸部材４２２にリンク機構を接続し、このリンク機構を引く又は押すことで開閉させる構成としておくことが好ましい。この場合の概略を図５に示しておく。なお、図中、（Ａ）は、リンク機構の棒状部材を引いて第二の把持部を閉じた状態の図を、（Ｂ）は、リンク機構の棒状部材を押して第二の把持部を閉じた状態の図をそれぞれ示しておく。
Further, each of the pair of sandwiching members 42 is configured to be paired with each other in the same manner as the structure of the first gripping portion 3. Each of the pair of sandwiching members 42 has a flat plate portion 421 for sandwiching an object. And a shaft member 422 for holding the sandwiching members 42 in an openable / closable state. In this embodiment, it is not limited as long as it can be opened and closed, but it is preferable that a link mechanism is connected to the shaft member 422 and the link mechanism is opened or closed by pulling or pushing. An outline of this case is shown in FIG. In the figure, (A) shows a state in which the rod-shaped member of the link mechanism is pulled and the second gripping portion is closed, and (B) shows a state in which the rod-shaped member of the link mechanism is pushed to close the second gripping portion . The figure of each state is shown.
ここで、本実施形態に係る手術用器具１の手術前動作について図面を用いて説明する。 Here, the operation before operation of the surgical instrument 1 according to the present embodiment will be described with reference to the drawings.
まず、術者は、通常の手法により、手術対象者の体表部に５〜１０ｍｍ程度の創を数箇所設け、トロカールを挿入し、そこから本実施形態に係る手術用器具を挿入する。なお挿入の際、本手術用器具は、各把持部の延伸方向が同一に揃えられ、直線状となっている。 First, the surgeon is provided with several wounds of about 5 to 10 mm on the body surface of the surgical subject by a normal technique, inserts a trocar, and inserts the surgical instrument according to the present embodiment therefrom. During insertion, the surgical instrument has a linear shape with the extending direction of each gripping part being the same.
まず、体内に本手術用器具を挿入後、術者は、所望の位置でワイヤを引くことによって第一の把持部３の挟み部材３１を開閉させ、ターゲットの臓器等を把持することができる。この状態の図は、上記図２に示したとおりである。この場合、折りたたんでいない状態のため、細い先端部によって細かい作業が可能となる。 First, after inserting the surgical instrument into the body, the surgeon can open and close the pinching member 31 of the first gripping section 3 by pulling a wire at a desired position to grip a target organ or the like. The diagram of this state is as shown in FIG. In this case, since it is not folded, fine work can be performed by the thin tip.
また、より大きな把持部が必要な場合には、術者はリンク機構を引きつつワイヤの張力を利用することで、折曲部４１を起点として第一の把持部３、第二の把持部のうち先端側の挟み部材４２を折り曲げ、第一の把持部３と主軸部２を平行になるように重ねる。この場合の折曲部４１近傍の概略は図３、４で示したとおりである。 Further, when a larger gripping part is required, the operator uses the tension of the wire while pulling the link mechanism, so that the first gripping part 3 and the second gripping part start from the bent part 41. Among them, the pinching member 42 on the distal end side is bent, and the first grip portion 3 and the main shaft portion 2 are overlapped so as to be parallel. The outline of the vicinity of the bent portion 41 in this case is as shown in FIGS.
そして、さらに、折り曲げた後、リンク機構を操作することで、第一の把持部３よりも大きな第二の把持部５を開閉させて、ターゲットを把持する。この開閉の状態については上記図５で示したとおりである。 Further, after bending, the second gripping unit 5 larger than the first gripping unit 3 is opened and closed by operating the link mechanism, and the target is gripped. The open / close state is as shown in FIG.
以上、本実施形態に係る手術用器具は、折り返すことで、異なる大きさの把持部を有し、様々なものを把持することができる。また、挿入後変形なしで把持部を使用することができ、折り曲げ回数も少ないため操作も容易である。更に一つの連結した部材を用いているためパーツ脱落のおそれも少ない手術用器具となっている。 As described above, the surgical instrument according to the present embodiment has the grip portions of different sizes by being folded back, and can grip various items. In addition, the grip portion can be used without deformation after insertion, and the operation is easy because the number of times of bending is small. Furthermore, since one connected member is used, the surgical instrument is less likely to drop off.
なお本実施形態では、各把持部の折り返しにワイヤを用いた例を示しているが、折曲部にアクチュエータを内蔵させて折り返しさせる構造とすることも可能である。 In the present embodiment, an example is shown in which a wire is used for folding each gripping portion. However, an actuator may be built in the folding portion and folded.
ここで、上記手術器具について、実際に作製し、その効果を確認した。この作製した器具の写真図を図６に示しておく。本実施例では、直線状態において、直径５ｍｍとし、折り曲げた場合における第二の把持部全体の幅は１０ｍｍとなるように設計した。上記の構造を採用して作製したところ、直線状態においては第一の把持部で、折り曲げた状態では第二の把持部でそれぞれ良好に物を把持することができることを確認した。
Here, about the said surgical instrument, it produced actually and confirmed the effect. A photograph of this produced instrument is shown in FIG. In the present embodiment, in the straight line state, the diameter is 5 mm, and the entire width of the second gripping portion when bent is designed to be 10 mm. As a result of employing the above-described structure, it was confirmed that an object can be satisfactorily gripped by the first gripping portion in a linear state and by the second gripping portion in a folded state .
本発明は、手術用器具として産業上の利用可能性がある。 The present invention has industrial applicability as a surgical instrument.
