医療用ステープラ Medical stapler
技術分野 Technical field
[0001] 本発明は、傷口を縫合するために使用される医療用ステープラに関する。 [0001] The present invention relates to a medical stapler used for suturing a wound.
背景技術 Background art
[0002] 一般に、外科手術等において傷口を縫合する手段として縫合糸のほかに医療用ス テーブルが使用されている。医療用ステープルは、クラウン部とその両側の弯曲部か ら下方に湾曲する脚部とを備える。医療用ステープラは、医療用ステーブルが装填さ れたヘッド部を有するステープラ本体と、ステープラ本体に回動可能に設けられた操 作レバーとを備える(例えば、 日本特許第 3054202号公報参照)。操作レバーは、ス ライダ本体力 離間する開き方向に付勢されている。傷口を縫合する際には、操作レ バーを強く握って閉じ方向に回動させる。医療用ステーブルは、ヘッド部から突出し て皮膚に刺し込まれ、各脚部が内側に折り曲げられとことによって傷口両側の皮膚を 寄せ、縫合する。 [0002] In general, a medical stable is used in addition to a suture as means for suturing a wound in a surgical operation or the like. The medical staple includes a crown portion and leg portions that curve downward from the bent portions on both sides thereof. The medical stapler includes a stapler main body having a head portion loaded with a medical stable, and an operation lever rotatably provided on the stapler main body (see, for example, Japanese Patent No. 3054202). The operating lever is urged in the opening direction to separate the slider body force. When stitching the wound, hold the operating lever firmly and rotate it in the closing direction. The medical stable protrudes from the head and is inserted into the skin, and the legs are bent inward to bring the skin on both sides of the wound together and suture.
[0003] 縫合糸で傷口を縫合する場合は、傷口の両側の糸通し孔間を縫合糸で縛る。した がって、抜糸した後も糸の痕が残ってしまうことが多い。これに対し、医療用ステープ ルの場合は、傷口両側の皮膚を寄せるだけで、医療用ステーブルのクラウン部が皮 膚に接触しない。このため、医療用ステーブルを取り外した後は、傷口の痕が残るだ けであり、一般的に手術痕がきれいである。したがって、医療用ステープラによる縫合 手術の普及が期待されてレ、る。 [0003] When a wound is sutured with a suture, the threading holes on both sides of the wound are tied with a suture. Therefore, it is often the case that the mark of the thread remains after the thread is removed. On the other hand, in the case of medical staples, the skin on both sides of the wound is brought close together, and the crown of the medical stable does not touch the skin. For this reason, after removing the medical stable, only the scar remains, and the surgical scar is generally clean. Therefore, the spread of sutures using medical staplers is expected.
[0004] 医療用ステープラは、使!/、捨てが基本である。医療用ステープラは、縫合手術の後 、内部に医療用ステーブルが何本残っているかに関係なぐ一手術が終わる毎に廃 棄処分される。 [0004] Medical staplers are basically used and discarded. The medical stapler is disposed of after each surgical operation, regardless of how many medical stables remain inside after the suture operation.
[0005] しかしながら、縫合手術後(すなわち、医療用ステープラの使用後)、何の処理もし ないで医療用ステープラを廃棄する場合、操作レバーは、開き方向に付勢されてい る。すなわち、操作レバーは、ステープラ本体に対して開き状態であり、ステープラ本 体から大きく突出するため、嵩張る。感染の危険がある医療廃棄物の処理費用は、
通常のごみ廃棄処理よりも高額である。したがって、廃棄物を減容することは、病院 の経費を節減する上で大きな課題である。 [0005] However, when the medical stapler is discarded without any treatment after the suture operation (that is, after use of the medical stapler), the operation lever is biased in the opening direction. That is, the operation lever is in an open state with respect to the stapler main body and protrudes greatly from the stapler main body, so that it is bulky. The cost of treating medical waste at risk of infection is More expensive than normal waste disposal. Therefore, reducing the volume of waste is a major challenge in saving hospital costs.
[0006] また、縫合手術では、医療用ステーブルに装填されている医療用ステーブルをす ベて使い切るとは限らない。すなわち、廃棄する医療用ステープラの中に医療用ステ 一プルが残留している場合が間々ある。このような医療用ステープラの入ったごみ袋 を処理する途中で操作レバーに外力が加わった場合、ステーブルが打ち出されてご み袋を突き破ってしまう可能性がある。その場合、患者の体液で汚染された医療用ス テーブルが露わになってしまい、不衛生である。 [0006] In addition, in a surgical operation, not all of the medical tables loaded on the medical table are used up. In other words, medical staples often remain in the medical stapler to be discarded. If an external force is applied to the control lever during processing of a garbage bag containing such a medical stapler, a stable may be punched out and break through the garbage bag. In this case, the medical table contaminated with the patient's body fluid is exposed and unsanitary.
[0007] 縫合が終了した後で、医療用ステープラ内に残っている医療用ステーブルをすベ て空打ちして、医療用ステーブルと医療用ステープラとを個別に廃棄処分する方法 もある。ところ力 空打ちに伴って打ち出された不要な医療用ステーブルは、手術室 内を汚したり、誤って患者に付着したりする虞もある。 [0007] There is also a method in which after completion of suturing, all the medical stables remaining in the medical stapler are blanked and the medical stable and the medical stapler are individually disposed of. However, there is a risk that unnecessary medical stables that are launched with force blanking may contaminate the operating room or accidentally adhere to the patient.
[0008] また、医療用ステープラを分解して廃棄することも考えられる。しかし、分解作業時 に細かな医療用ステーブルを取り扱わなくてはならない不便さがある。また、分解作 業のなかで手術室内に細かな部品が飛び散る虞もある。 [0008] It is also conceivable to disassemble and discard the medical stapler. However, there is the inconvenience of having to handle fine medical stables during disassembly. There is also a risk that small parts will scatter in the operating room during the disassembly work.

A coil spring 15 is disposed in the base portion 13. One end of the coil spring 15 is attached to the guide portion 16 of the slider 14. Engagement holes 21 are formed above and below the rear portion of the base portion 13. The engagement piece 17 of the slider 14 is engaged with the engagement hole 21, and the slider 14 is slidably attached within the range of the length of the engagement hole 21. The slider 14 is always urged backward by the coil panel 15.
[0021] また、ベース部 13には、スライダ 14の両側の位置に係止片(係止受け部) 22が後 方に突出形成されている。 In addition, the base portion 13 is formed with locking pieces (locking receiving portions) 22 protruding rearward at positions on both sides of the slider 14.
[0022] 一方、図 2に示されるように、操作レバー 2には、ガイド溝 23が形成されている。ガイ ド溝 23は、スライダ 14がコイルパネ 15により付勢されて係合駒 17が係合穴 21の後 縁部に位置しているときの係合顎部 19を内包する。そして、操作レバー 2が回動する 時に、操作レバー 2を係合顎部 19に対してスライド可能にガイドする。ガイド溝 23の 下端部には、スライダ 14の係合顎部 19に係合可能な係合突部 25 (図 1参照)が形成 されている。 On the other hand, as shown in FIG. 2, a guide groove 23 is formed in the operation lever 2. The guide groove 23 includes the engagement jaw portion 19 when the slider 14 is urged by the coil panel 15 and the engagement piece 17 is positioned at the rear edge portion of the engagement hole 21. Then, when the operation lever 2 rotates, the operation lever 2 is slidably guided with respect to the engaging jaw portion 19. An engaging protrusion 25 (see FIG. 1) that can engage with the engaging jaw 19 of the slider 14 is formed at the lower end of the guide groove 23.
[0023] ガイド溝 23の両側には、スライダ 14の両側に配置された係止片 22に対応する位置 に係止部 24が形成されている。係止部 24の上面は前下りに傾斜している。 Locking portions 24 are formed on both sides of the guide groove 23 at positions corresponding to the locking pieces 22 arranged on both sides of the slider 14. The upper surface of the locking portion 24 is inclined forward and downward.
[0024] ストツバ機構は、スライダ 14に形成された係合顎部 19と、操作レバー 2に形成され た係合突部 25を備える。操作レバー 2を通常の縫合に必要な回動量まで回動させた とき、操作レバー 2の係合突部 25の上面がスライダ 14の係合顎部 19の下面に係合 する。また、ロック機構は、ベース 13に形成された係止片 22と操作レバー 2に形成さ れた係止部 24とを備える。操作レバー 2を通常の縫合に必要な回動量以上に回動さ せたとき、操作レバー 2の係止部 24がベース 13の係止片 22を弾性変形させて係止 片 22の上面側に乗り越える。 The stocker mechanism includes an engaging jaw portion 19 formed on the slider 14 and an engaging protrusion 25 formed on the operation lever 2. When the operation lever 2 is rotated to a rotation amount necessary for normal stitching, the upper surface of the engagement protrusion 25 of the operation lever 2 is engaged with the lower surface of the engagement jaw 19 of the slider 14. Further, the lock mechanism includes a locking piece 22 formed on the base 13 and a locking portion 24 formed on the operation lever 2. When the operating lever 2 is rotated more than the amount required for normal stitching, the locking portion 24 of the operating lever 2 elastically deforms the locking piece 22 of the base 13 and moves to the upper surface side of the locking piece 22. get over.
[0025] 次に、医療用ステープラの作動態様につ!/、て説明する。傷口を縫合するときは、へ ッド部 3の先端を傷口両側の皮膚 30の上に押し当てる。そして、図 3A、図 3B、及び 図 5に示されるように、操作レバー 2を収納部 8内に収納する閉じ方向に回動させて、
ヘッド部 3の打ち出し部 4に供給されたステープル SIを押圧する。このとき、ステープ ル S 1の中央部は、アンビル 7に支持され、それ以上下方には移動しない。これに対 し、ステープル S1の両側部は、ドライバプレート 5の両側の突片 6に押圧される。した がって、ステープル S 1の各脚部は押し下げられ、それぞれアンビル 7の両端を中心 に互いに近づくように曲がって!/、く。操作レバー 2を回動端まで回動させて!/、く中で、 各脚部は皮膚 30に刺し込まれ、内側に折り曲げながら傷口両側の皮膚 30を引き寄 せて、縫合する。 Next, an operation mode of the medical stapler will be described. When suturing the wound, press the tip of head 3 onto the skin 30 on both sides of the wound. Then, as shown in FIG. 3A, FIG. 3B, and FIG. 5, the operating lever 2 is rotated in the closing direction in which it is stored in the storage portion 8, The staple SI supplied to the launch unit 4 of the head unit 3 is pressed. At this time, the central portion of the staple S 1 is supported by the anvil 7 and does not move further downward. On the other hand, both side portions of the staple S1 are pressed by the protruding pieces 6 on both sides of the driver plate 5. Therefore, the legs of the staple S 1 are pushed down and bent to approach each other around the ends of the anvil 7! Rotate the control lever 2 to the end of rotation! In each of the legs, the legs are inserted into the skin 30 and folded to the inside while pulling the skin 30 on both sides of the wound and stitching.
[0026] その後、操作レバー 2に対する力を解除してグリップ部 11をハウジング 9の収納部 8 力、らはみ出す開き方向に復帰させることにより(図 1参照)、ステーブル S1はヘッド部 3から排出され、傷口の 1個所の縫合が終了する。この縫合操作を傷口に応じて適宜 繰り返すことにより傷口全体の縫合が完成する。 [0026] After that, by releasing the force on the operating lever 2 and returning the grip portion 11 to the retracting direction of the housing portion 8 of the housing 9 and protruding (see FIG. 1), the stable S1 is ejected from the head portion 3. The stitching at one point of the wound is completed. This stitching operation is repeated as appropriate according to the wound to complete stitching of the entire wound.
[0027] 上述のように、縫合時には、操作レバー 2を通常の縫合に必要な回動量まで回動さ せる。このとき、図 5に示されるように、上方に回動させた操作レバー 2の係合突部 25 の上面は、スライダ 14の係合顎部 19の下面に係合するため、操作レバー 2はそれ以 上上方に回動できない。このようなストツバ機構により、操作レバー 2が通常の縫合に 必要な回動量よりも閉じ方向に回動するのを確実に規制できる。 [0027] As described above, at the time of sewing, the operation lever 2 is rotated to a rotation amount necessary for normal sewing. At this time, as shown in FIG. 5, the upper surface of the engaging protrusion 25 of the operating lever 2 rotated upward is engaged with the lower surface of the engaging jaw portion 19 of the slider 14. It cannot be rotated upward any further. With such a stagger mechanism, it is possible to reliably restrict the operation lever 2 from rotating in the closing direction beyond the amount of rotation required for normal stitching.
[0028] 全ての縫合操作終了後、医療用ステープラは廃棄される。図 6に示されるように、ス ライダ 14の背面部 20に指を掛けてコイルバネ 15の付勢力に抗してスライダ 14を前 方に押し出してストツバ機構を解除する。その状態を維持しながら操作レバー 2を握り 込んで収納部 8内に収納する閉じ方向に回動させる。その際、操作レバー 2の係合 突部 25はスライダ 14の係合顎部 19に係合しないので、操作レバー 2は縫合時に必 要な回動量よりも閉じ方向に回動させることができる。このとき、図 7に示されるように、 操作レバー 2の係止部 24の上面がステープラ本体 1の係止片 22を弾性変形させて、 係止部 24が係止片 22の上面側へ乗り越える。その後、操作レバー 2の握りこみを解 放しても、操作レバー 2の係止部 24はステープラ本体 1の係止片 22に係止する。こ のようなロック機構により、操作レバー 2は、係止位置にロックされ、それ以上下方に 回動できない。 [0028] After completion of all the suturing operations, the medical stapler is discarded. As shown in FIG. 6, a finger is put on the back surface portion 20 of the slider 14 and the slider 14 is pushed forward against the urging force of the coil spring 15 to release the strobe mechanism. While maintaining this state, the control lever 2 is grasped and rotated in the closing direction in which it is stored in the storage portion 8. At this time, since the engagement protrusion 25 of the operation lever 2 does not engage with the engagement jaw 19 of the slider 14, the operation lever 2 can be rotated in the closing direction rather than the rotation amount necessary for sewing. At this time, as shown in FIG. 7, the upper surface of the locking portion 24 of the operation lever 2 elastically deforms the locking piece 22 of the stapler body 1, and the locking portion 24 gets over the upper surface side of the locking piece 22. . Thereafter, even if the grip of the operation lever 2 is released, the locking portion 24 of the operation lever 2 is locked to the locking piece 22 of the stapler body 1. By such a locking mechanism, the operation lever 2 is locked at the locking position and cannot be rotated further downward.
[0029] 以上のロック操作により、操作レバー 2はステープラ本体 1の収納部 8に収納されて
、ステープラ本体 1と操作レバー 2とが接近する状態が保たれる。したがって、医療用 ステープラ全体の容積は小さくなる。その結果、医療用ステープラを廃棄したときの 嵩を小さくすること力 Sでき、医療用廃棄物の減容化に資することができる。また、医療 用ステープラを分解することなく廃棄できるから、手術室内を汚したりする虞がなレ、。 [0029] With the above locking operation, the operation lever 2 is stored in the storage portion 8 of the stapler body 1. The stapler body 1 and the operating lever 2 are kept close to each other. Therefore, the volume of the entire medical stapler is reduced. As a result, it is possible to reduce the bulk when the medical stapler is discarded, which can contribute to volume reduction of medical waste. In addition, since the medical stapler can be discarded without disassembling, there is no risk of contaminating the operating room.
[0030] また、操作レバー 2は、最終的にはステーブル S 1を折り曲げる閉じ方向に回動させ た状態で係止される。したがって、ヘッド部 3内部に残留した先頭のステープル S 1の 針先部は、図 3Bに示されるように、内側に折り曲げられた状態で固定されている。す なわち、ステープラ本体 1からステーブル S 1の針先部が突出することがない。したが つて、医療用ステープラが廃棄されているごみ袋を処理する途中で操作レバー 2に 外力が加わっても、ステーブル S 1がごみ袋を突き破って露わになる虞がなぐ廃棄 作業を安全に行うことができる。また、残留ステーブルを残したまま、医療用ステープ ラを分解することなく廃棄できるから、手術室内を汚したりする虞がない。したがって、 医療機関従事者だけでなぐ医療器具の廃棄業者も含めた医療ごみの廃棄に携わ る作業者全体にとつて、衛生的に廃棄処理を行なえるようになる。 [0030] Further, the operation lever 2 is finally locked in a state of being rotated in a closing direction in which the stable S1 is bent. Therefore, the leading end portion of the leading staple S 1 remaining inside the head portion 3 is fixed in a state of being bent inward as shown in FIG. 3B. In other words, the needle tip of the stable S 1 does not protrude from the stapler body 1. Therefore, even if an external force is applied to the control lever 2 during the processing of the waste bag that is being disposed of by the medical stapler, the disposal operation that the Stable S 1 breaks through the waste bag and exposes it is safe. Can be done. Further, since the medical stapler can be discarded without disassembling while leaving the remaining stable, there is no possibility of contaminating the operating room. Therefore, sanitary disposal can be performed for all workers involved in the disposal of medical waste, including those who dispose of medical equipment, only by medical institutions.
[0031] さらに、通常の縫合時には、ストツバ機構により操作レバー 2が必要な回動量よりも 閉じ方向に回動するのが規制される。ストツバ機構を解除するという操作が無ければ 、ロック機構を作動させることはできない。したがって、縫合操作の際、特段、操作レ バー 2の回動量や力の入れ加減を意識して操作する必要がない。 [0031] Further, at the time of normal stitching, the operation of the operating lever 2 in the closing direction is restricted by the stove mechanism more than the necessary amount of rotation. The lock mechanism cannot be operated without an operation to release the stagger mechanism. Therefore, there is no need to perform the operation with particular attention to the amount of rotation of the operation lever 2 and the force applied during the suturing operation.
[0032] し力、も、ロック機構では、スライダ 14とは別にステープラ本体 1のベース部 13に形成 された係止片 22と、操作レバー 2に形成された係止部 24とが互いに係止する。した 力 Sつて、係止片 22と係止部 24とを係止させた後でスライダ 14を移動させても操作レ バー 2が開き方向に回動することはなぐ操作レバー 2の閉じ状態を確実に保持する こと力 Sでさる。 [0032] In the locking mechanism, in the locking mechanism, the locking piece 22 formed on the base portion 13 of the stapler body 1 and the locking portion 24 formed on the operation lever 2 are locked to each other separately from the slider 14. To do. Therefore, even if the slider 14 is moved after the locking piece 22 and the locking portion 24 are locked, the operating lever 2 does not rotate in the opening direction. Hold it securely with force S.
[0033] なお、上述の実施形態とは逆に、スライダ 14と係止片 22とを操作レバー 2側に、係 合突部 25と係止部 24をステープラ本体 1側に配設してもよい。 [0033] Contrary to the above-described embodiment, the slider 14 and the locking piece 22 may be disposed on the operation lever 2 side, and the engagement protrusion 25 and the locking portion 24 may be disposed on the stapler body 1 side. Good.
[0034] また、ロック機構は、上述の実施例に限定されな!/、。例えば、ロック機構は、スライダ 14と操作レバー 2のいずれか一方に形成された係止部 24と、いずれか他方に形成 された係止受け部 22とを備えてもよい。この場合、ロック機構は、係止部 24を係止受
け部 22に係止させることにより、操作レバー 2が開き方向に回動不可能にロックされ、 かつスライダ 14がスライド不可能にロックされるように構成してもよい。 [0034] Further, the locking mechanism is not limited to the above-mentioned embodiment! /. For example, the lock mechanism may include a locking portion 24 formed on one of the slider 14 and the operation lever 2 and a locking receiving portion 22 formed on either of the other. In this case, the lock mechanism latches and receives the latching portion 24. By engaging with the hook portion 22, the operation lever 2 may be locked so as not to rotate in the opening direction, and the slider 14 may be locked so as not to slide.
