Description

本発明は、子宮摘出後の膣断端を縫合する際の補助具に関する。   The present invention relates to an assisting tool for suturing a vaginal stump after hysterectomy.

腹腔鏡下子宮摘出手術は、例えば下記の特許文献１に示された子宮マニピュレータを用いて行われる。具体的には、膣に子宮マニピュレータを挿入して子宮を所定の姿勢で保持した状態で、腹腔鏡を用いてレーザメス等で膣円蓋を切開することにより子宮を切離し、切離した子宮を腹腔内から摘出する。   The laparoscopic hysterectomy operation is performed using, for example, a uterine manipulator disclosed in Patent Document 1 below. Specifically, with the uterine manipulator inserted into the vagina and holding the uterus in a predetermined posture, the uterus is cut by cutting the vaginal fornix with a laser knife using a laparoscope, and the cut uterus is cut into the abdominal cavity. Extract from.

特表平１０−５０７３８４号公報Japanese Patent Publication No. 10-507384

子宮を摘出した後、膣の切断開口部（膣断端）が閉鎖縫合されるが、膣断端の場所を確認しながら縫合する作業は容易ではない。また、膣断端の縫合は、気腹ガスで腹腔を膨らませた状態で行われるため、この気腹ガスの膣からの漏れだしを防止する措置を講じる必要がある。例えば、上記の子宮マニピュレータからバルーンを取り外し、このバルーンを膣内に挿入して膨らませることで膣からの気腹ガスの漏れ出しを防止することもある。しかし、子宮マニピュレータからバルーンを取り外す手間がかかる上、縫合用の針がバルーンに刺さらないように気を付けながら縫合する必要があるため、縫合がしにくい。   After removing the uterus, the vaginal cutting opening (vaginal stump) is closed and sutured, but the operation of suturing while confirming the location of the vaginal stump is not easy. Further, since the vaginal stump is sutured while the abdominal cavity is inflated with pneumoperitoneum gas, it is necessary to take measures to prevent the pneumoperitoneum gas from leaking from the vagina. For example, the balloon may be removed from the uterine manipulator described above, and the balloon may be inserted into the vagina and inflated to prevent leakage of pneumoperitoneum gas from the vagina. However, it takes time to remove the balloon from the uterine manipulator, and it is difficult to suture because it is necessary to suture while being careful not to puncture the balloon with a suturing needle.

そこで、本発明は、子宮摘出後の膣断端の縫合を容易化すると共に、縫合時の膣からの気腹ガスの漏れ出しを防止することを目的とする。   Therefore, an object of the present invention is to facilitate the suturing of the vaginal stump after hysterectomy and prevent the leakage of pneumoperitoneum gas from the vagina at the time of suturing.

前記課題を解決するために、本発明は、膣の開口部から挿入され、先端で膣断端を内側から支持する略円筒状の本体と、前記本体の基端に設けられたグリップとを備えた膣断端縫合補助具であって、前記本体の外周面に、前記先端よりも大径なガス漏れ防止部が設けられた膣断端縫合補助具を提供する。   In order to solve the above-mentioned problems, the present invention comprises a substantially cylindrical main body that is inserted from the opening of the vagina and supports the vaginal stump from the inside at the tip, and a grip provided at the base end of the main body. Also provided is a vaginal stump suture assisting tool, wherein a gas leak prevention part having a larger diameter than the tip is provided on the outer peripheral surface of the main body.

子宮を摘出した後、膣断端を縫合する際、上記の膣断端縫合補助具のグリップを持って略円筒状の本体を膣の開口部から挿入し、本体の先端で膣断端を支持することにより、膣断端の場所が分かりやすくなり、縫合が容易化される。また、本体の外周面に、先端より大径なガス漏れ防止部を設け、このガス漏れ防止部を膣の内壁に密着させることで、膣からの気腹ガスの漏れ出しを防止することができる。   When the vaginal stump is sutured after the uterus is removed, hold the grip of the above-mentioned vaginal stump suture aid and insert the approximately cylindrical body from the opening of the vagina, and support the vaginal stump at the tip of the body By doing so, the location of the vaginal stump becomes easier to understand, and suturing is facilitated. Further, by providing a gas leakage prevention portion having a diameter larger than the tip on the outer peripheral surface of the main body and closely contacting this gas leakage prevention portion with the inner wall of the vagina, it is possible to prevent the insufflation gas from leaking from the vagina. ..

ガス漏れ防止部としては、例えば、本体の外周面に環状突起を設けることができる。このとき、環状突起を本体の周方向（すなわち、本体の軸心と直交する円形）に設けると、本体を膣に挿入する際、環状突起が膣の内壁に引っかかって挿入が阻害される恐れがある。そこで、環状突起を、本体の軸心と直交する面に対して傾斜した楕円形とすれば、環状突起が膣の内壁に引っかかりにくくなるため、本体の挿入がしやすくなる。   As the gas leakage prevention portion, for example, an annular protrusion can be provided on the outer peripheral surface of the main body. At this time, if the annular projection is provided in the circumferential direction of the main body (that is, a circle perpendicular to the axis of the main body), when the main body is inserted into the vagina, the annular projection may be caught on the inner wall of the vagina and hinder the insertion. is there. Therefore, if the annular projection is formed into an elliptical shape that is inclined with respect to a plane orthogonal to the axis of the main body, the annular projection is less likely to be caught on the inner wall of the vagina, and thus the main body can be easily inserted.

また、ガス漏れ防止部として、本体の外周面に、基端へ向けて徐々に拡径したテーパ面を設けることができる。このテーパ面を膣の内周に挿入することにより、先端よりも大径な部分が膣の内周面と密着するため、膣の内周面と本体の外周面との間からのガス漏れを規制することができる。   Further, as the gas leakage prevention portion, a taper surface whose diameter gradually increases toward the base end can be provided on the outer peripheral surface of the main body. By inserting this tapered surface into the inner circumference of the vagina, the part with a diameter larger than the tip will be in close contact with the inner circumference of the vagina, so gas leakage between the inner circumference of the vagina and the outer circumference of the body will be prevented. Can be regulated.

以上のように、本発明の膣断端縫合補助具を用いれば、子宮摘出後の膣断端の縫合が容易化されると共に、縫合時の膣からの気腹ガスの漏れ出しを防止することができる。   As described above, the use of the vaginal stump suturing aid of the present invention facilitates suturing of the vaginal stump after hysterectomy and prevents leakage of pneumoperitoneum gas from the vagina during suturing. You can

本発明の一実施形態に係る膣断端縫合補助具１は、図１に示すように、先端１０ａが開口した略円筒状の本体１０を有する。本体１０の先端１０ａは、例えば図２に示すように、本体１０の軸心と直交する面に対して傾斜した面上に形成される。本体１０の基端には、グリップ３が設けられる。本体１０は樹脂で一体成形され、本実施形態では、本体１０及びグリップ２０が樹脂で一体成形されている。尚、以下の説明では、本体１０の軸心方向（図２の左右方向）を「軸方向」と言う。   As shown in FIG. 1, a vaginal stump suture assisting tool 1 according to an embodiment of the present invention has a substantially cylindrical main body 10 having an open tip 10a. The tip 10a of the main body 10 is formed, for example, as shown in FIG. 2, on a surface inclined with respect to a surface orthogonal to the axis of the main body 10. A grip 3 is provided at the base end of the main body 10. The main body 10 is integrally formed of resin, and in the present embodiment, the main body 10 and the grip 20 are integrally formed of resin. In the following description, the axial center direction of the main body 10 (left-right direction in FIG. 2) is referred to as “axial direction”.

本体１０は、先端１０ａを含む領域に設けられた円筒状の小径部１１と、基端を含む領域に設けられ、小径部１１よりも大径な円筒状の大径部１２と、これらを連続する円すい状のテーパ部１３とを備える。本体１０の外径は、患者の膣の大きさに合わせて設定される。換言すると、径が異なる複数種の膣断端縫合補助具１を用意しておき、患者の膣の大きさに合った外径の膣断端縫合補助具１を使用する。本体１０のうち、グリップ２０よりも先端側の領域が、膣内に挿入され得る有効領域Ｌとなる（図２参照）。   The main body 10 has a cylindrical small-diameter portion 11 provided in a region including the tip 10a, a cylindrical large-diameter portion 12 provided in a region including the base end and having a diameter larger than that of the small-diameter portion 11, and these are connected to each other. And a tapered taper portion 13 having a conical shape. The outer diameter of the main body 10 is set according to the size of the patient's vagina. In other words, a plurality of types of vaginal stump suture aids 1 having different diameters are prepared, and the vaginal stump suture aid 1 having an outer diameter suitable for the size of the patient's vagina is used. A region of the main body 10 on the tip side of the grip 20 is an effective region L that can be inserted into the vagina (see FIG. 2).

本体１０には、図３に示すように、軸方向に貫通する内孔１５が設けられる。図示例では、本体１０の基端に設けられた内孔１５の開口部を閉塞する蓋部材１６が設けられる。蓋部材１６は、例えば樹脂で形成され、ねじ締結や圧入等の適宜の手段で本体１０に固定される。尚、蓋部材１６は、上記のように本体１０と別体に形成する他、本体１０と一体成形してもよい。   As shown in FIG. 3, the main body 10 is provided with an inner hole 15 penetrating in the axial direction. In the illustrated example, a lid member 16 that closes the opening of the inner hole 15 provided at the base end of the main body 10 is provided. The lid member 16 is made of resin, for example, and is fixed to the main body 10 by appropriate means such as screw fastening or press fitting. The lid member 16 may be formed separately from the main body 10 as described above, or may be integrally formed with the main body 10.

本体１０には、図１に示すように、円筒状の外周面から外径に突出した環状突起１４が設けられる。この環状突起１４が、気腹ガスの外部への漏れだしを防止する第１のガス漏れ防止部として機能する。図示例では、小径部１１の外周面の軸方向に離隔した複数箇所に環状突起１４が設けられる。各環状突起１４は、本体１０の外周全周に連続して設けられる。各環状突起１４は、軸方向に直交する面に対して傾斜した楕円形を成している。図示例では、複数の環状突起１４が平行に設けられ、特に、先端１０ａと平行な面上に設けられている。図４に示すように、小径部１１の円筒状外周面に対する環状突起１４の半径方向の突出量Ｈ１〜Ｈ４は、基端側に行くほど徐々に大きくなっている（Ｈ１＜Ｈ２＜Ｈ３＜Ｈ４）。   As shown in FIG. 1, the main body 10 is provided with an annular protrusion 14 protruding from the outer peripheral surface of the cylindrical shape to the outer diameter. The annular projection 14 functions as a first gas leakage prevention portion that prevents the insufflation gas from leaking to the outside. In the illustrated example, the annular protrusions 14 are provided on the outer peripheral surface of the small-diameter portion 11 at a plurality of positions spaced apart in the axial direction. Each annular protrusion 14 is continuously provided on the entire outer circumference of the main body 10. Each annular protrusion 14 has an elliptical shape inclined with respect to a plane orthogonal to the axial direction. In the illustrated example, the plurality of annular protrusions 14 are provided in parallel, and in particular, they are provided on a plane parallel to the tip 10a. As shown in FIG. 4, the radial projection amounts H1 to H4 of the annular projection 14 with respect to the cylindrical outer peripheral surface of the small-diameter portion 11 gradually increase toward the base end side (H1 <H2 <H3 <H4). ).

本体１０のテーパ部１３の外周面（テーパ面１３ａ）は、気腹ガスの外部への漏れだしを防止する第２のガス漏れ防止部として機能する。テーパ面１３ａは、基端側へ行くにつれて徐々に大径となっている。テーパ面１３ａの最大径（すなわち、大径部１２の外径）は、例えば小径部１１の外径の１１０〜１３０％の範囲に設定される。図示例では、テーパ面１３ａの最大径が、複数の環状突起１４のうちの最小径の環状突起１４（突出量Ｈ１）よりも大径に設定され、具体的には、複数の環状突起１４のうちの最大径の環状突起１４（突出量Ｈ４）と同程度に設定される。テーパ面１３ａは、環状突起１４とグリップ２０との間の軸方向領域に設けられる。テーパ面１３ａの軸方向寸法は、比較的大きく設定され、例えば本体１０の有効領域Ｌの軸方向寸法の２０％以上に設定される。これにより、テーパ面１３ａの母線の軸方向に対する傾斜角度が小さくなり、基端へ向けて外径が緩やかに大きくなる形状が得られる。   The outer peripheral surface (tapered surface 13a) of the tapered portion 13 of the main body 10 functions as a second gas leakage prevention portion that prevents the insufflation gas from leaking to the outside. The tapered surface 13a gradually becomes larger in diameter toward the base end side. The maximum diameter of the tapered surface 13a (that is, the outer diameter of the large diameter portion 12) is set in the range of 110 to 130% of the outer diameter of the small diameter portion 11, for example. In the illustrated example, the maximum diameter of the tapered surface 13a is set to be larger than the smallest diameter annular protrusion 14 (protrusion amount H1) of the plurality of annular protrusions 14, and specifically, the plurality of annular protrusions 14a. It is set to the same level as the maximum diameter of the annular projection 14 (projection amount H4). The tapered surface 13 a is provided in an axial region between the annular protrusion 14 and the grip 20. The axial dimension of the tapered surface 13a is set to be relatively large, for example, 20% or more of the axial dimension of the effective region L of the main body 10. As a result, the inclination angle of the tapered surface 13a with respect to the axial direction of the generatrix is reduced, and a shape in which the outer diameter is gradually increased toward the base end is obtained.

図５は、子宮１０１（点線で示す）を摘出した後の腹腔内の断面図であり、図中上側が腹部側、図中下側が背部側である。子宮１０１を摘出した後、膣１０２の切断開口部（膣断端１０２ａ）を腹腔鏡下手術により腹部側から縫合する。   FIG. 5 is a cross-sectional view of the inside of the abdominal cavity after the uterus 101 (shown by the dotted line) is removed, and the upper side in the figure is the abdominal side and the lower side in the figure is the dorsal side. After removing the uterus 101, the cutting opening (vaginal stump 102a) of the vagina 102 is sewn from the abdominal side by laparoscopic surgery.

具体的には、まず、施術者が、膣断端縫合補助具１のグリップ２０を掴んで、膣１０２の自然開口部に本体１０の先端１０ａを挿入する。このとき、膣断端縫合補助具１の本体１０の外周面に環状突起１４が設けられているため、本体１０の膣１０２内への挿入が阻害されることが懸念される。本実施形態では、環状突起１４が軸方向（すなわち本体１０の挿入方向）と直交する面に対して傾斜しているため、環状突起１４が膣１０２の内壁に引っかかりにくくなる。さらに、複数の環状突起１４の外径（突出量Ｈ１〜Ｈ４：図４参照）が基端側ほど大きくなっているため、先に外径の小さな環状突起１４が挿入された後、少しずつ外径の大きな環状突起１４が順に挿入され、これにより環状突起１４が膣１０２の内壁にさらに引っかかりにくくなる。以上により、環状突起１４を有する本体１０を膣１０２内にスムーズに挿入することができる。   Specifically, first, the practitioner grasps the grip 20 of the vaginal stump suture assisting tool 1 and inserts the tip 10a of the main body 10 into the natural opening of the vagina 102. At this time, since the annular projection 14 is provided on the outer peripheral surface of the main body 10 of the vaginal stump suture assist tool 1, there is a concern that the insertion of the main body 10 into the vagina 102 may be hindered. In the present embodiment, since the annular protrusion 14 is inclined with respect to the plane orthogonal to the axial direction (that is, the insertion direction of the main body 10), the annular protrusion 14 is unlikely to be caught by the inner wall of the vagina 102. Furthermore, since the outer diameters of the plurality of annular protrusions 14 (protrusion amounts H1 to H4: see FIG. 4) are larger toward the proximal end side, after the annular protrusions 14 having the smaller outer diameter are inserted first, the outer diameter is gradually increased. The annular projections 14 having a large diameter are sequentially inserted, which makes it more difficult for the annular projection 14 to be caught on the inner wall of the vagina 102. As described above, the main body 10 having the annular protrusion 14 can be smoothly inserted into the vagina 102.

こうして膣１０２に挿入された本体１０の先端１０ａで、膣断端１０２ａが膣１０２の内側から支持される。この状態で、腹腔内に気腹ガスを充填する。このとき、本体１０の外周面は膣１０２の内壁に密着しているが、これらの間から気腹ガスが外部へ漏れ出すことが懸念される。本実施形態では、本体１０の外周面に、先端１０ａの外径（すなわち、小径部１１の円筒状外周面の外径）よりも大径な環状突起１４が設けられ、この環状突起１４が膣１０２の内壁に密着することで、気腹ガスの外部への漏れ出しが規制される。特に、図示例では、本体１０の外周面に複数の環状突起１４が設けられるため、ガス漏れ防止効果が高められる。さらに、本体１０の外周面に、小径部１１の外周面から徐々に拡径したテーパ面１３ａが設けられ、このテーパ面１３ａが膣１０２の内壁に密着することで、気腹ガスの外部への漏れ出しがより確実に規制される。   The vaginal stump 102a is supported from the inside of the vagina 102 by the tip 10a of the main body 10 thus inserted into the vagina 102. In this state, the abdominal cavity is filled with pneumoperitoneum gas. At this time, the outer peripheral surface of the main body 10 is in close contact with the inner wall of the vagina 102, but there is a concern that the pneumoperitoneum gas may leak to the outside from between them. In this embodiment, the outer peripheral surface of the main body 10 is provided with an annular protrusion 14 having a diameter larger than the outer diameter of the tip 10a (that is, the outer diameter of the cylindrical outer peripheral surface of the small-diameter portion 11). By tightly contacting the inner wall of 102, the leakage of pneumoperitoneum gas to the outside is regulated. Particularly, in the illustrated example, since the plurality of annular protrusions 14 are provided on the outer peripheral surface of the main body 10, the gas leakage prevention effect is enhanced. Further, the outer peripheral surface of the main body 10 is provided with a tapered surface 13a that is gradually expanded in diameter from the outer peripheral surface of the small-diameter portion 11, and the tapered surface 13a is in close contact with the inner wall of the vagina 102, so that the pneumoperitoneum gas is exposed to the outside. Leakage is regulated more reliably.

上記の環状突起１４（第１のガス漏れ防止部）及びテーパ面１３ａ（第２のガス漏れ防止部）は、何れか一方のみを設けた場合でも効果はあるが、本実施形態のように両方設けた方が効果が高い。本実施形態では、本体１０の外周面が、膣１０２の膣断端１０２ａから自然開口部に至る略全域に密着しているため、この外周面に、複数の楕円形の環状突起１４とテーパ面１３ａとを軸方向に並べて設けることができる。   The annular protrusion 14 (first gas leakage prevention portion) and the tapered surface 13a (second gas leakage prevention portion) are effective even if only one of them is provided, but both are the same as in the present embodiment. It is more effective if it is provided. In the present embodiment, the outer peripheral surface of the main body 10 is in close contact with the vaginal stump 102a of the vagina 102 over substantially the entire area thereof, so that a plurality of elliptical annular projections 14 and tapered surfaces are provided on the outer peripheral surface. 13a can be provided side by side in the axial direction.

そして、施術者が、腹腔鏡を用いて腹部側から膣断端１０２ａを縫合する。このとき、膣断端１０２ａが、膣断端縫合補助具１の本体１０の先端１０ａで内側から支持されているため、膣断端１０２ａの場所を確認しやすい。特に、図５に示すように、本体１０の先端１０ａのうち、基端側に後退した部分が上側（腹部側）となるように、本体１０を配置することで、膣断端１０２ａ（特に背部側部分）が腹部側から見えやすくなる。また、本体１０の先端１０ａで膣断端１０２ａを支持することで、膣断端１０２ａの組織が引っ張られるため、膣断端１０２ａに縫合針を刺しやすくなる。以上により、腹部側からの膣断端１０２ａの縫合が容易化される。   Then, the practitioner sutures the vaginal stump 102a from the abdominal side using a laparoscope. At this time, since the vaginal stump 102a is supported from the inside by the tip 10a of the main body 10 of the vaginal stump suture auxiliary device 1, it is easy to confirm the location of the vaginal stump 102a. In particular, as shown in FIG. 5, by arranging the main body 10 so that the part of the front end 10a of the main body 10 that is retracted toward the base end side is the upper side (abdominal side), the vaginal stump 102a (particularly the back part). The side part) is easily visible from the abdominal side. Further, by supporting the vaginal stump 102a with the tip 10a of the main body 10, the tissue of the vaginal stump 102a is pulled, so that the vaginal stump 102a can be easily pierced with a suture needle. As described above, suturing of the vaginal stump 102a from the abdominal side is facilitated.

本発明は上記の実施形態に限られない。例えば、上記の実施形態では、環状突起１４が４箇所に設けられた場合を示したが、これに限らず、環状突起１４を３箇所以下、あるいは５箇所以上に設けてもよい。また、上記の実施形態では、小径部１１の外周面に環状突起１４を設けているが、これに代えてあるいはこれに加えて、テーパ面１３ａや大径部１２の外周面に環状突起を設けてもよい。   The present invention is not limited to the above embodiment. For example, in the above embodiment, the case where the annular protrusions 14 are provided at four locations has been described, but the present invention is not limited to this, and the annular protrusions 14 may be provided at three locations or less, or five locations or more. In the above embodiment, the annular protrusion 14 is provided on the outer peripheral surface of the small diameter portion 11, but instead of or in addition to this, the annular protrusion is provided on the outer peripheral surface of the tapered surface 13a or the large diameter portion 12.
