Description

かしめ工具Crimping tool
　本発明は、体内に埋め込まれる線状部材の一端に取り付けられた固定具に該線状部材の他端側を挿通し、挿通部位をかしめて該線状部材に該固定具を固定するかしめ工具に関する。 The present invention relates to a caulking tool for inserting the other end of the linear member into a fixture attached to one end of the linear member embedded in the body, and caulking the insertion site to fix the fixture to the linear member. About.

　従来この種のかしめ工具としては、下記に特許文献１に示すように、一対のハンドルを互いに交差させると共に回動自在に連結したジョイント部を有し、ジョイント部によりハンドルの接近動作に対して先端が接近動作するように構成した工具が知られている。
Conventionally, as this type of caulking tool, as shown in Patent Document 1 below, a pair of handles intersect with each other and have a joint portion that is pivotally connected, and the tip of the handle approaches the handle by the joint portion. There is known a tool configured to move close to each other.
　かかるかしめ工具によれば、ジョイント部と先端動作部とのストロークを大きくすることで、小さな切開創でも深部で固定具をかしめることが可能となる。 According to such a caulking tool, it is possible to caulk the fixing tool in the deep part even with a small incision by increasing the stroke between the joint part and the tip action part.
特表２００９－５３４１０７号公報Special table 2009-534107 gazette
　しかしながら、従来のかしめ工具では、ジョイント部と先端動作部との距離が長いため、ハンドルの操作による先端動作部の微妙な動作が困難であった。特に、線状部材に取り付けられた固定具は、通常、緩みを生じさせないために、１度のかしめ動作しか許容されていない。そのため、このようなかしめ動作は、術者に慎重さを要求するものとして過度の負担となっていた。 However, in the conventional caulking tool, since the distance between the joint portion and the tip action portion is long, it is difficult to perform a delicate operation of the tip action portion by operating the handle. In particular, the fixing tool attached to the linear member normally allows only one caulking operation in order not to cause loosening. For this reason, such a caulking operation is an excessive burden as requiring the operator to be cautious.
　一方で、ジョイント部と先端動作部とのストロークを小さくした場合には、動作部の動作精度を向上させることができるものの、深部で固定具をかしめるためには、ジョイント部まで切開創に挿入する必要が生じ、切開創を大きくせざるを得ないという問題があった。 On the other hand, when the stroke between the joint part and the tip action part is reduced, the action accuracy of the action part can be improved, but in order to caulk the fixture in the deep part, the joint part is inserted into the incision. There is a problem that the incision must be enlarged.
　上記の事情に鑑みて、本発明は、低侵襲で操作性に優れたかしめ工具を提供することを目的とする。 In view of the above circumstances, an object of the present invention is to provide a crimping tool that is minimally invasive and excellent in operability.
　第１発明のかしめ工具は、体内に埋め込まれる線状部材に取り付けられた固定具をかしめて該線状部材に該固定具を固定するかしめ工具であって、
　片手で把持可能な把持部を一端側に有する一対のハンドルと、
　一端が前記一対のハンドルの他端に連結されると共に、他端に前記固定具をかしめる先端かしめ部を有する一対の可動片と
を備え、
　前記一対のハンドルは、
　他端側に該一対のハンドルを互いに回動自在に連結した第１ジョイント部を有し、該第１ジョイント部により前記把持部の接近動作に対して他端が離反動作し、
　前記一対の可動片は、
　一端に前記一対のハンドルの他端に回転自在にそれぞれ連結された一対の第２ジョイント部を有すると共に、前記先端かしめ部と該一対の第２ジョイント部との間に該一対の可動片を互いに回転自在に連結した第３ジョイント部とを有し、該第３ジョイント部により該一対の第２ジョイント部の離反動作に対して該先端かしめ部が接近動作し、
　前記把持部が離反した状態で、前記一対の第２ジョイント部が互いに当接する当接部を有し、該当接部と前記第１ジョイント部および前記第３ジョイント部との間に間隙が形成されることを特徴とする。 The caulking tool of the first invention is a caulking tool for caulking a fixing tool attached to a linear member embedded in the body and fixing the fixing tool to the linear member,
A pair of handles having a grip portion on one end side that can be gripped with one hand;
One end is connected to the other end of the pair of handles, and a pair of movable pieces having a tip caulking portion for caulking the fixing tool to the other end,
The pair of handles is
Having a first joint part rotatably connecting the pair of handles to the other end side, and the other end of the first joint part is moved away from the approaching action of the gripping part;
The pair of movable pieces are:
A pair of second joint portions rotatably connected to the other ends of the pair of handles at one end; and the pair of movable pieces between the tip caulking portion and the pair of second joint portions. A third joint part rotatably connected, and the tip caulking part moves closer to the separating operation of the pair of second joint parts by the third joint part,
In a state where the gripping parts are separated from each other, the pair of second joint parts have contact parts that contact each other, and a gap is formed between the corresponding contact part, the first joint part, and the third joint part. It is characterized by that.
　第１発明のかしめ工具によれば、一対のハンドルの第１ジョイント部と先端かしめ部との間に一対の第２ジョイント部および第３ジョイント部を設けることで、第１ジョイント部と先端かしめ部とのストロークを大きくすることができる。 According to the caulking tool of the first invention, the first joint portion and the tip caulking portion are provided by providing the pair of second joint portion and third joint portion between the first joint portion and the tip caulking portion of the pair of handles. And the stroke can be increased.
　ここで、一対の第２ジョイント部は、把持部が離反した状態で、前記一対の第２ジョイント部が互いに当接して径が最小となるため、当該かしめ工具を切開創に挿入する際に第２ジョイント部が障害となることがない。さらに、先端かしめ部と第３ジョイント部とのストロークは小さいことから、先端かしめ部が切開創に挿入される際に大きく開いて障害となることもない。 Here, since the pair of second joint portions are in contact with each other and the diameter is minimized with the gripping portion separated from each other, the second joint portion has a first diameter when the caulking tool is inserted into the incision. 2 Joint part does not become an obstacle. Furthermore, since the stroke between the tip caulking portion and the third joint portion is small, the tip caulking portion does not open greatly when inserted into the incision and does not become an obstacle.
　これにより、小さな切開創でも深部で固定具をかしめることができ、低侵襲を実現することができる。 This makes it possible to squeeze the fixture in the deep part even with a small incision, and to achieve minimal invasiveness.
　さらに、把持部と先端かしめ部とは、第１ジョイント部、一対の第２ジョイント部および第３ジョイント部でそれぞれ回転自在に連結され、先端かしめ部は、第３ジョイント部からの（第１ジョイント部からのストロークに比して非常に）小さなストロークで、精度よく動作させることができる。 Further, the gripping portion and the tip caulking portion are rotatably connected by a first joint portion, a pair of second joint portions and a third joint portion, respectively, and the tip caulking portion is connected to the first joint portion (first joint It is possible to operate with high accuracy with a small stroke (very much smaller than the stroke from the part).
　ここで、前記一対の第２ジョイント部に互いに当接する当接部を設けることで、一対のハンドルおよび一対の可動片の動作開始位置を規定することができる。さらに、当接部と第１ジョイント部および第３ジョイント部との間に間隙を形成することで、動作時の一対のハンドル間および一対の可動片間の偏り等を間隙形状により確認することができ、先端かしめ部の動作精度を維持することができる。 Here, by providing the abutting portions that abut each other on the pair of second joint portions, the operation start positions of the pair of handles and the pair of movable pieces can be defined. Further, by forming a gap between the contact portion and the first joint portion and the third joint portion, it is possible to check the deviation between the pair of handles and the pair of movable pieces during operation by the gap shape. It is possible to maintain the operation accuracy of the tip caulking portion.
　このように、第１発明のかしめ工具によれば、低侵襲で操作性に優れたかしめ工具を提供することができる。 Thus, according to the caulking tool of the first invention, it is possible to provide a caulking tool that is minimally invasive and excellent in operability.
　第２発明のかしめ工具によれば、第１発明において、
　前記一対のハンドルは、前記把持部を離反状態に保持する弾性部材を備えることを特徴とする。 According to the caulking tool of the second invention, in the first invention,
The pair of handles includes an elastic member that holds the grip portion in a separated state.
　第２発明のかしめ工具によれば、かしめ工具を切開創に挿入する際には、先端かしめ部が開いた状態であることが望ましい。ここで、一対の可動片側に弾性部材を設けて先端かしめ部を開いた状態に保持することも考えられるが、先端かしめ部の動作精度を確保する観点からは、一対のハンドルに弾性部材を設けて把持部を離反状態に保持することで、先端かしめ部の動作精度を維持しつつ、操作性をさらに向上させることができる。 According to the caulking tool of the second invention, when the caulking tool is inserted into the incision, it is desirable that the tip caulking portion is open. Here, it is conceivable that an elastic member is provided on the pair of movable pieces to hold the tip caulking portion in an open state. However, from the viewpoint of ensuring the operation accuracy of the tip caulking portion, an elastic member is provided on the pair of handles.

　ハンドル連結部１２，１２´は、第１ジョイント部１０が一対のハンドル１，１´の他端側に設けられることにより、把持部１１，１１´の接近動作の変位量に対応するハンドル連結部１２，１２´が離反動作の変位量が小さくなるようになっている。 The handle coupling portions 12 and 12 'are provided with the first joint portion 10 on the other end side of the pair of handles 1 and 1', so that the handle coupling portions corresponding to the displacement amount of the approaching operation of the gripping portions 11 and 11 'are provided. 12, 12 'is designed to reduce the displacement amount of the separating operation.
　次に、一対の可動片３，３´は、第３ジョイント部３０により互いに回動可能に連結され、第３ジョイント部３０に対して一端側にハンドル連結部１２，１２´と連結する可動片連結部３１，３１´を備え、他端側に固定具Ｙをかしめる先端かしめ部３２，３２´を備える。 Next, the pair of movable pieces 3 and 3 ′ are connected to each other by the third joint portion 30 so as to be rotatable, and are connected to the handle joint portions 12 and 12 ′ on one end side with respect to the third joint portion 30. It is provided with connecting portions 31, 31 ', and is provided with tip caulking portions 32, 32' for caulking the fixture Y on the other end side.
　第３ジョイント部３０は、一対の可動片３，３´の内側面の互いに対向する位置を軸着したものであり、可動片連結部３１，３１´の離反動作に対して先端かしめ部３２，３２´が接近動作する。なお、第３ジョイント部３０の構造については後述する（同様の構造である第２ジョイント部２０を用いて詳細に説明する）。 The third joint portion 30 is formed by axially attaching the mutually facing positions of the inner side surfaces of the pair of movable pieces 3, 3 ′, and the tip caulking portion 32, with respect to the separating operation of the movable piece connecting portions 31, 31 ′. 32 'approaches. In addition, the structure of the 3rd joint part 30 is mentioned later (it demonstrates in detail using the 2nd joint part 20 which is the same structure).
　可動片連結部３１，３１´は、第２ジョイント部２０，２０´により互いに回動可能にハンドル連結部１２，１２´と連結される。 The movable piece connecting portions 31 and 31 ′ are connected to the handle connecting portions 12 and 12 ′ so as to be rotatable with respect to each other by the second joint portions 20 and 20 ′.
　ここで、第２ジョイント部２０は、図１に部分拡大図で示すように、可動片連結部３１の先端の上側および下側が円形に加工された可動片連結凸部３１ａ，３１ａとなっており、これに対応するように、ハンドル連結部１２の先端の上側および下側が円形に抉られたハンドル連結凹部１２ａ，１２ａとなっている。 Here, as shown in a partially enlarged view in FIG. 1, the second joint portion 20 has movable piece coupling convex portions 31 a and 31 a in which the upper and lower sides of the distal end of the movable piece coupling portion 31 are processed into a circular shape. In order to correspond to this, the upper and lower ends of the front end of the handle connecting portion 12 are formed as handle connecting recesses 12a and 12a that are rounded.
　一方、ハンドル連結部１２の先端の中間位置（上側と下側との間）は円形に加工されたハンドル連結凸部１２ｂとなっており、これに対応するように、可動片連結部３１の先端の中間位置（上側と下側との間）は円形に抉られた可動片連結凹部（図示省略）となっている。 On the other hand, an intermediate position (between the upper side and the lower side) of the tip of the handle connecting portion 12 is a handle connecting convex portion 12b processed into a circular shape, and the tip of the movable piece connecting portion 31 is corresponding to this. The intermediate position (between the upper side and the lower side) is a movable piece coupling recess (not shown) that is wound in a circular shape.
　このように、ハンドル連結部１２および可動片連結部３１の先端が、可動片連結凸部３１ａ，３１ａの間にハンドル連結凸部１２ｂが入れ子状になるように配置され、これらを貫くようにそれぞれ設けられた貫通孔（図示省略）にビス２０ａが貫通される。ビス２０ａは、挿入先端側が抜け止めのため潰してあり抜け止め部２０ｂとなっている。なお、ビス２０ａの頭部２０ｃは、背面側に配置されている。 As described above, the distal ends of the handle connecting portion 12 and the movable piece connecting portion 31 are arranged so that the handle connecting convex portion 12b is nested between the movable piece connecting convex portions 31a and 31a, and penetrate through these. Screws 20a are passed through the provided through holes (not shown). The screw 20a is crushed on the insertion tip side to prevent the screw 20a from coming off and forms a retaining portion 20b. The head 20c of the screw 20a is disposed on the back side.
　以上のように構成された第２ジョイント部２０,２０´は、第１ジョイント部１０および第３ジョイント部３０についても同様の構成となっている。 The second joint part 20, 20 ′ configured as described above has the same structure with respect to the first joint part 10 and the third joint part 30.
　すなわち、第１ジョイント部１０は、一対のハンドル１，１´の内側面の互いに対向する位置が、互いに入れ子状になっており、これらを貫くようにそれぞれ設けられた貫通孔（図示省略）にビスが貫通される。ビスは、挿入先端側が抜け止めのため潰してあり抜け止め部１０ｂとなっている。なお、ビスの頭部１０ｃは、背面側に配置されている。 That is, the first joint portion 10 is formed such that the inner surfaces of the pair of handles 1 and 1 ′ are opposed to each other, and are inserted into through holes (not shown) provided so as to penetrate the first joint portion 10. Screw is penetrated. The screw is crushed on the insertion tip side to prevent it from coming off and forms a retaining portion 10b. The screw head 10c is disposed on the back side.
　また、第３ジョイント部３０は、一対の可動片３，３´の内側面の互いに対向する位置が、互いに入れ子状になっており、これらを貫くようにそれぞれ設けられた貫通孔（図示省略）にビスが貫通される。ビスは、挿入先端側が抜け止めのため潰してあり抜け止め部３０ｂとなっている。なお、ビスの頭部３０ｃは、背面側に配置されている。 In addition, the third joint portion 30 has mutually nested positions on the inner side surfaces of the pair of movable pieces 3 and 3 ′, and through holes (not shown) respectively provided so as to penetrate these third joint portions 30. Screws are penetrated through. The screw is crushed on the insertion tip side to prevent it from coming off and forms a retaining portion 30b. The screw head 30c is disposed on the back side.
　なお補足すると、第２ジョイント２０は、ハンドル連結部１２および可動片連結部３１の先端の回動量が、第１ジョイント部１０および第３ジョイント部３０に比して大きいため、第２ジョイント２０,２０´のみ、その内側面および外側面を上下方向に切り欠いた切欠部２１,２１,２１´,２１´が形成されている。切欠部２１,２１,２１´,２１´は、ハンドル連結部１２および可動片連結部３１の先端の回動する際に、その端部同士が接触することを回避する遊びとなっている。　先端かしめ部３２,３２´は、その先端が上下方向において削り落とされて肉薄部３３となっており、肉薄部３３の対向する先端挟持部には、固定具Ｙを挟む凹部３３ａ,３３ａ´が形成されている。 In addition, since the second joint 20 has a larger amount of rotation at the tips of the handle connecting portion 12 and the movable piece connecting portion 31 than the first joint portion 10 and the third joint portion 30, the second joint 20, Only 20 'is formed with notches 21, 21, 21', 21 'in which the inner side surface and the outer side surface are notched in the vertical direction. The notches 21, 21, 21 ′, 21 ′ are play that prevents the ends from contacting each other when the tips of the handle connecting part 12 and the movable piece connecting part 31 are rotated. The tip caulking portions 32 and 32 ′ are scraped off in the vertical direction to form a thin portion 33, and the tip sandwiching portions opposed to the thin portion 33 have concave portions 33 a and 33 a ′ sandwiching the fixture Y. Is formed.
　肉薄部３３は、凹部３３ａ,３３ａ´の一端側の位置が、先端かしめ部３２,３２´同士の接近位置を規制する規制部３３ｂ,３３ｂ´（本発明の形成部材に相当する）となっている。 The thin portion 33 has restriction portions 33b and 33b ′ (corresponding to the forming members of the present invention) in which the positions of the concave portions 33a and 33a ′ at one end side restrict the approach positions of the tip caulking portions 32 and 32 ′. Yes.
　なお、肉薄部３３は、上下方向が均等に削り落とされているわけではなく、背面側から正面側に向って先端が傾斜している。これにより、固定具Ｙをかしめる際に、固定具Ｙの向きに応じて、術者はかしめ工具の正面側と背面側を使い分けることができる。 Note that the thin portion 33 is not evenly cut off in the vertical direction, and the tip is inclined from the back side to the front side. Thereby, when the fixing tool Y is caulked, the surgeon can selectively use the front side and the back side of the caulking tool according to the direction of the fixing tool Y.
　以上のように構成されたかしめ工具は、図１および図２に示すように、板バネ１３,１３´により一対のハンドル１,１´の把持部１１,１１´が互いに離反状態に保持される。 In the caulking tool configured as described above, as shown in FIGS. 1 and 2, the gripping portions 11, 11 ′ of the pair of handles 1, 1 ′ are held apart from each other by the leaf springs 13, 13 ′. .
　このとき、一対のハンドル１,１´の他端側のハンドル連結部１２,１２´は、互いに接近すると共に、第２ジョイント部２０,２０´で連結された可動片３,３´の可動片連結部３１,３１´も接近する。そして、これらの内側面同士（第２ジョイント部２０,２０´の内側面同士）が当接する（当接部４０）。 At this time, the handle connecting portions 12 and 12 'on the other end side of the pair of handles 1 and 1' approach each other, and the movable pieces 3 and 3 'connected by the second joint portions 20 and 20'. The connecting portions 31 and 31 'also approach. Then, these inner side surfaces (inner side surfaces of the second joint portions 20 and 20 ′) abut (the abutting portion 40).
　この状態で、当接部４０に対して、第１ジョイント部１０側および第３ジョイント部３０側に間隙５０ａおよび５０ｂを形成しておくことで、かしめ工具の滅菌の際に、一対のハンドル１,１´のハンドル連結部１２,１２´の間や可動片３,３´の可動片連結部３１,３１´の間への高温蒸気の流入を促進することができる。 In this state, the gaps 50a and 50b are formed on the first joint portion 10 side and the third joint portion 30 side with respect to the abutting portion 40, so that the pair of handles 1 are sterilized when the caulking tool is sterilized. , 1 'between the handle connecting portions 12 and 12' and between the movable piece connecting portions 31 and 31 'of the movable pieces 3 and 3'.
　さらに、この状態から図３に示すように、術者が把持部１１，１１´を把持してこれらを接近動作させると、第１ジョイント部１０を支点として、ハンドル連結部１２,１２´が離反動作し、これに伴って、第２ジョイント部２０,２０´により連結された可動片連結部３１,３１´が離反動作する。 Further, from this state, as shown in FIG. 3, when the operator grasps the gripping portions 11 and 11 ′ and moves them closer, the handle connecting portions 12 and 12 ′ are separated from each other with the first joint portion 10 as a fulcrum. In operation, the movable piece connecting portions 31 and 31 ′ connected by the second joint portions 20 and 20 ′ are separated from each other.
　このとき、間隙５０ａおよび５０ｂが開いて一体の間隙５０となり、この間隙５０の形状により、動作時の一対のハンドル１,１´および一対の可動片３,３の偏り等を確認することができ、かしめ工具の動作精度を維持することができる。　そして、可動片連結部３１,３１´が離反動作することで、第３ジョイント部３０を支点として、先端かしめ部３２,３２´が接近動作して、凹部３３ａ,３３ａ´がその間に位置する固定具Ｙをかしめる。 At this time, the gaps 50a and 50b are opened to form an integral gap 50. By the shape of the gap 50, it is possible to confirm the deviation of the pair of handles 1, 1 'and the pair of movable pieces 3, 3 during operation. The operation accuracy of the caulking tool can be maintained. Then, the movable piece connecting portions 31 and 31 ′ move away from each other, so that the tip caulking portions 32 and 32 ′ approach each other with the third joint portion 30 as a fulcrum, and the concave portions 33 a and 33 a ′ are positioned between them. Caulking tool Y.
　このとき、先端かしめ部３２,３２´同士の接近位置を規制する規制部３３ｂ,３３ｂ´が最初に当接して、圧縮具Ｙが必要以上に圧縮変形されることを防止することができる。なお、規制部３３ｂ,３３ｂ´が当接した状態で、肉薄部３３の先端同士にはわずかな間隙が形成されており、先端部の破損が防止される。また、規制部３３ｂ,３３ｂ´の当接部と第３ジョイント部３０との間に間隙６０が形成される。 At this time, the restricting portions 33b and 33b 'for restricting the approach positions of the crimping portions 32 and 32' at the front end first come into contact with each other to prevent the compression tool Y from being compressed and deformed more than necessary. Note that a slight gap is formed between the tips of the thin portion 33 in a state where the restricting portions 33b and 33b ′ are in contact with each other, and the tip portion is prevented from being damaged. Further, a gap 60 is formed between the contact portion of the restricting portions 33 b and 33 b ′ and the third joint portion 30.
　以上説明したかしめ工具によれば、第１ジョイント部１０、一対の第２ジョイント部２０,２０´および第３ジョイント部３０を設けることで、第１ジョイント部１０と先端かしめ部３２とのストロークを大きくすることができる。 According to the caulking tool described above, the stroke between the first joint portion 10 and the tip caulking portion 32 is provided by providing the first joint portion 10, the pair of second joint portions 20, 20 ', and the third joint portion 30. Can be bigger.
　さらに、一対の第２ジョイント部２０,２０´は、把持部１１,１１´が離反した状態で、互いに当接して径が最小となるため、当該かしめ工具を切開創に挿入する際に第２ジョイント部２０,２０´が障害となることがない。さらに、先端かしめ部３２,３２´と第３ジョイント部３０とのストロークは小さいことから、先端かしめ部３２,３２´が切開創に挿入される際に大きく開いて障害となることもない。 Further, since the pair of second joint portions 20 and 20 ′ are in contact with each other and the diameter is minimized in a state where the grip portions 11 and 11 ′ are separated from each other, when the caulking tool is inserted into the incision, The joint portions 20 and 20 'do not become an obstacle. Furthermore, since the stroke between the tip caulking portions 32 and 32 'and the third joint portion 30 is small, the tip caulking portions 32 and 32' are not greatly opened when inserted into the incision, and there is no obstacle.
　これにより、小さな切開創でも深部で固定具Ｙをかしめることができ、低侵襲を実現することができる。 Thereby, the fixing tool Y can be caulked deeply even with a small incision, and minimally invasive can be realized.
　加えて、把持部１０,１０´と先端かしめ部３２,３２´とは、第１ジョイント部１０、一対の第２ジョイント部２０,２０´および第３ジョイント部３０でそれぞれ回転自在に連結され、先端かしめ部３２,３２´は、第３ジョイント部３０からの小さなストロークで、精度よく動作させることができる。 In addition, the gripping portions 10, 10 ′ and the tip caulking portions 32, 32 ′ are rotatably connected by the first joint portion 10, the pair of second joint portions 20, 20 ′, and the third joint portion 30, respectively. The tip caulking portions 32 and 32 ′ can be accurately operated with a small stroke from the third joint portion 30.
　このように、本実施形態のかしめ工具によれば、低侵襲で操作性に優れたかしめ工具を提供することができる。 Thus, according to the caulking tool of this embodiment, it is possible to provide a caulking tool that is minimally invasive and excellent in operability.
