本発明は、傷口を縫合するために使用される外科用ステープルを傷口から取り外すための外科用ステープルリムーバに関する。  The present invention relates to a surgical staple remover for removing surgical staples used to suture a wound from a wound.

一般に、外科用ステープルリムーバによって外科用ステープルを抜針するとき、抜針されたステープルは衛生管理上適宜の位置に置かれたトレイ等に入れておく必要がある。ところが、抜針された外科用ステープルを患者の傷口からトレイに移すときに床に落下させてしまったりするなどして、散逸させてしまうおそれがある。また、抜針した外科用ステープルをトレイ内へ移動したのちであっても、トレイ内で外科用ステープルがむき出しになっているので、抜針した外科用ステープルが看護士や処理業者等の手に触れたりする可能性がある。  In general, when a surgical staple is removed by a surgical staple remover, the removed staple needs to be placed in a tray or the like placed at an appropriate position for hygiene management. However, when the removed surgical staple is transferred from the patient's wound to the tray, the surgical staple may be dropped on the floor or the like, which may be dissipated. Even after moving the removed surgical staples into the tray, the surgical staples are exposed in the tray. There is a possibility of touching.

そのため、安全性を考慮して、外科用ステープルを抜針したら直ちに安全な場所に収納できるように、抜針した外科用ステープルをスライド移動させてそのまま安全な収納部に移動させる構成の外科用ステープルリムーバが開発されている。
特願2004−351365公報
Therefore, in consideration of safety, the surgical staple having a configuration in which the removed surgical staple is slid and moved to the safe storage portion as it is so that the surgical staple can be immediately stored in a safe place when the surgical staple is extracted. A remover has been developed.
Japanese Patent Application No. 2004-351365

ところで、抜針された外科用ステープルは人の手に触れないようにするだけでなく、数えなければならない。手術時には何本の外科用ステープルを使用して縫合したかがカルテに記入されており、使用本数と同数だけ抜針することを確認することにより、初めて手術が完了したということができるからである。  By the way, the removed surgical staples must be counted as well as not touching human hands. This is because the number of surgical staples used for suturing at the time of surgery is written in the medical chart, and it can be said that the operation has been completed for the first time by confirming that the number of needles to be removed is the same as the number used. .

しかしながら、上述のように単に収納部に外科用ステープルを収納しただけでは、何本の外科用ステープルを抜針したかを知ることはできない。また、たとえ収納部を透明にしても、外科用ステープルが互いに重なり合っているときは数えにくいという問題があった。  However, it is not possible to know how many surgical staples have been removed simply by storing surgical staples in the storage section as described above. Moreover, even if the storage portion is transparent, there is a problem that it is difficult to count when the surgical staples overlap each other.

本発明は上述の問題点を解消し、安全であるとともに抜針した外科用ステープルの数が数えやすい外科用ステープルリムーバを提供することをその課題とする。  SUMMARY OF THE INVENTION An object of the present invention is to provide a surgical staple remover that solves the above-mentioned problems and is safe and easy to count the number of surgical staples that have been removed.

請求項1に係る発明は、皮膚を縫合した外科用ステープルのクラウン部の両側下部に入り込んで上記外科用ステープルを支持する針支持部と、上記針支持部で支持された上記外科用ステープルのクラウン部の中央上部を押圧して上記外科用ステープルを変形させて皮膚から抜き出し、上記針支持部から連続形成された1対の平行な針受け部に沿って上記外科用ステープルをスライドさせる押圧用スライダと、該押圧用スライダにより引き込まれた外科用ステープルを収納する収納部とを備えた外科用ステープルリムーバにおいて、上記収納部の内部を目視可能に形成するとともに、上記針受け部には、上記押圧用スライダによって引き込まれた外科用ステープルの1本のそれぞれと係合可能な複数の係合凹部を連続的に形成したことを特徴とする。  According to a first aspect of the present invention, there is provided a needle support portion for supporting the surgical staple by entering both lower portions of the crown portion of the surgical staple having sutured skin, and the crown of the surgical staple supported by the needle support portion. A pressing slider for pressing the central upper part of the section to deform the surgical staple and pulling it out of the skin, and sliding the surgical staple along a pair of parallel needle receiving sections formed continuously from the needle support section And a storage portion for storing the surgical staple pulled in by the pressing slider, the inside of the storage portion is formed so as to be visible, and the needle receiving portion has the pressing portion A plurality of engaging recesses that can be engaged with each of the surgical staples drawn by the slider are continuously formed. That.

請求項2に係る発明は、請求項1において、上記針受け部に連続的に形成された係合凹部のうち最も上記針支持部側にある係合凹部は、上記押圧用スライダが上記外科用ステープルの引き込み時に上記針受け部に沿ってスライド可能な移動範囲の端部までスライドしたときに引き込まれた上記外科用ステープルが係合可能な位置に形成されていることを特徴とする。

請求項3に係る発明によれば、請求項1又は2において、上記係合凹部は鋸歯状に形成されていることを特徴とする。  According to a third aspect of the present invention, in the first or second aspect, the engaging recess is formed in a sawtooth shape.

請求項1に係る発明によれば、抜針された外科用ステープルは押圧用スライダにより収納部に引き込まれるが、引き込まれた外科用ステープルは連続する複数の係合凹部のそれぞれと1本ずつ係合する。係合凹部を備えた1対の針受け部は平行に設けられているので、外科用ステープルは係合凹部に安定し、整然と並んだ状態で保持される。したがって、何本の外科用ステープルを抜いたかは、収納部の外から目視によって数えることができる。したがって、外科医は縫合に使用した外科用ステープルの本数と抜針した外科用ステープルの本数が同じか違うかを容易かつ確実に確認することができる。  According to the first aspect of the present invention, the extracted surgical staple is pulled into the storage portion by the pressing slider, and the pulled surgical staple is engaged with each of the plurality of continuous engaging recesses. Match. Since the pair of needle receiving portions provided with the engagement recesses are provided in parallel, the surgical staple is stably held in the engagement recesses and arranged in an orderly manner. Therefore, how many surgical staples are pulled out can be counted visually from the outside of the storage section. Therefore, the surgeon can easily and reliably check whether the number of surgical staples used for suturing is the same as or different from the number of removed surgical staples.

請求項2に係る発明によれば、さらに上記針受け部に連続的に形成された係合凹部のうち最も上記押圧用スライダ側にある係合凹部は、少なくとも上記押圧用スライダが上記外科用ステープルの引き込み時に上記針受け部に沿ってスライド可能な移動範囲の端部までスライドしたときに引き込まれた上記外科用ステープルが係合可能な位置に形成されているから、一度引き込まれて係合凹部に送られた外科用ステープルは必ず係合凹部に係合するので、押圧用スライダが元の位置に戻っても、係合凹部に係合した外科用ステープルは安定しているから、押圧用スライダとともに動くことはない。According to the second aspect of the present invention, among the engagement recesses formed continuously in the needle receiving portion, the engagement recess closest to the pressing slider is at least the pressing slider is thesurgical staple. Since the surgical staple retracted when it is slid tothe end of the movable range slidable along the needle receiving portion at the time of retraction is formed at a position where it can be engaged, Since the surgical staple sent to is always engaged with the engaging recess, even if the pressing slider returns to its original position, the surgical staple engaged with the engaging recess is stable. It does not move with.

請求項3に係る発明によれば、さらに係合凹部が鋸歯状に形成されているから、係合凹部に係合した外科用ステープルは安定し、押圧用スライダとともに動くことはない。また、押圧用スライダによってさらに押し込まれたときは、円滑に動いて次の係合凹部に係合することができる。  According to the invention ofclaim 3, since the engaging recess is formed in a sawtooth shape, the surgical staple engaged with the engaging recess is stable and does not move with the pressing slider. Further, when it is further pushed in by the pressing slider, it can move smoothly and engage with the next engaging recess.

図1は外科用ステープルリムーバの斜視図であり、図2はその縦断面図を示す。上図1において符号1は外科用ステープルリムーバを示す。この外科用ステープルリムーバ1は、主に本体部2と押圧用スライダ3と針受け支持部材4とから構成されている。  FIG. 1 is a perspective view of a surgical staple remover, and FIG. 2 is a longitudinal sectional view thereof. In FIG. 1, reference numeral 1 denotes a surgical staple remover. The surgical staple remover 1 mainly includes amain body 2, apressing slider 3, and a needle receivingsupport member 4.

本体部2は細長の箱形で透明な合成樹脂によって形成されている。本体部2の前端には取込開口部5が形成され、また本体部2の内部には収納部6を構成する空間が形成されている。上記取込開口部5は収納部6に連続している。本体部2の上部中央には、その長手方向に沿ってガイド溝7が形成されている。このガイド溝7の下部にはガイド通路8が形成されている。なお、収納部6は外部から内部を目視できる構成であればよく、必ずしも本体部2を透明にする構成に限定されない。収納部6に内部を覗き込めるようなスリット状の透明窓部を形成する構成であってもよい。  Themain body 2 is formed of an elongated box-shaped and transparent synthetic resin. A taking-in opening 5 is formed at the front end of themain body 2, and a space constituting the storage portion 6 is formed inside themain body 2. The intake opening 5 is continuous with the storage 6. A guide groove 7 is formed at the upper center of themain body 2 along the longitudinal direction thereof. A guide passage 8 is formed in the lower portion of the guide groove 7. In addition, the storage part 6 should just be the structure which can visually observe the inside from the outside, and is not necessarily limited to the structure which makes the main-body part 2 transparent. The structure which forms the slit-shaped transparent window part which can look inside at the accommodating part 6 may be sufficient.

押圧用スライダ3はスライダ本体3aと押圧レバー10と針押し部11とから構成されている。スライダ本体3aは上記ガイド通路8に摺動自在に設けられ、バネ12によって常時前方に移動するように付勢されている。スライダ本体3aの上部には凸部13が形成され、この凸部13はガイド溝7に係合し、スライダ本体3aの前後の移動端を規制している。  Thepressing slider 3 includes aslider body 3a, apressing lever 10 and aneedle pressing portion 11. Theslider body 3a is slidably provided in the guide passage 8 and is urged by aspring 12 so as to always move forward. Aconvex portion 13 is formed on the upper portion of the slidermain body 3a, and thisconvex portion 13 engages with the guide groove 7 to restrict the front and rear moving ends of the slidermain body 3a.

押圧レバー10は、上記凸部13の前端から斜め前方に突出し、その先端上部には指掛け部14が形成されている。押圧レバー10はその基部から下方に曲り変形するように弾性材料によって形成されている。  Thepressing lever 10 protrudes obliquely forward from the front end of theconvex portion 13, and afinger hook portion 14 is formed at the top of the tip. Thepressing lever 10 is made of an elastic material so as to bend and deform downward from its base.

針押し部11は押圧レバー10の前端の指掛け部14の下方に突出形成され、さらにその先端は、前部の係合部15が後部の押圧部16より突出して鉤形に形成されている。なお、針押し部11は強度を要求されるから、金属などの硬質の素材によって構成するのが好ましい。  Theneedle pressing portion 11 is formed so as to protrude below thefinger hooking portion 14 at the front end of thepressing lever 10, and the front end of theneedle pressing portion 11 is formed in a bowl shape with the front engagingportion 15 protruding from the rearpressing portion 16. In addition, since theneedle pushing part 11 is requested | required of intensity | strength, it is preferable to comprise with hard raw materials, such as a metal.

次に、針受け支持部材4は金属によって構成され、前部がU字形に形成された部材で、このU字形の針支持部17の前部から1対の平行な針受け部18が後方に連続形成されている。なお、U字形の針支持部17は図3(a)に示されるように、外科用ステープラによって折り曲げられた外科用ステープル20と皮膚21との間に差し込まれて外科用ステープル20のクラウン部22の両側を下から支持するもので、その幅は上記外科用ステープル20のクラウン部22の幅よりも少し狭い程度に形成され、またクラウン部22と外科用ステープル20との間に差し込みやすいように肉厚も薄く形成されている。  Next, the needlereceiver support member 4 is made of metal and has a front portion formed in a U shape, and a pair of parallelneedle receiver portions 18 are rearward from the front portion of the U-shapedneedle support portion 17. It is continuously formed. 3A, the U-shapedneedle support portion 17 is inserted between thesurgical staple 20 bent by a surgical stapler and theskin 21, and thecrown portion 22 of thesurgical staple 20 is inserted. The width of thesurgical staple 20 is formed so as to be slightly narrower than the width of thecrown portion 22 of thesurgical staple 20 so that it can be easily inserted between thecrown portion 22 and thesurgical staple 20. The wall thickness is also thin.

針支持部17は本体部2の収納部6の取込開口部5から前方に突出し、また針受け部18は本体部2の収納部6内に収まるように配置され、適宜手段によって固定されている。また、上記針受け部18には、上記収納部6内において連続する係合凹部23が形成されている。係合凹部23は鋸歯状に形成された歯と歯との間に形成され、前後に隣り合う係合凹部23の間隔は約ステープル1〜1.5本分の幅と略同じ程度になるように設定されている。そして、最も手前(最前部)にある係合凹部23aは、上記押圧用スライダ3が移動端までスライドしたときの係合部15の後面の略直上部にあるように設定されている。さらに、通常の外科手術で使用される外科用ステープルの本数は30〜40本程度であり、上記係合凹部23の数もこれに合わせて決めればよい。  Theneedle support portion 17 projects forward from the take-in opening 5 of the storage portion 6 of themain body portion 2, and theneedle receiving portion 18 is disposed so as to be accommodated in the storage portion 6 of themain body portion 2, and is fixed by appropriate means. Yes. Further, theneedle receiving portion 18 is formed with an engagingconcave portion 23 that is continuous in the storage portion 6. Theengagement recess 23 is formed between teeth formed in a sawtooth shape, and the interval between theengagement recesses 23 adjacent to each other in the front-rear direction is approximately the same as the width of about 1 to 1.5 staples. Is set to The engagement recess 23a located in the foremost (frontmost part) is set so as to be substantially directly above the rear surface of theengagement part 15 when thepressing slider 3 slides to the moving end. Furthermore, the number of surgical staples used in a normal surgical operation is about 30 to 40, and the number of theengaging recesses 23 may be determined according to this.

次に、上記構成の外科用ステープルリムーバ1の作用について説明する。まず、片手で本体部2を持ち、図3(a)に示されるように、傷口を縫合した外科用ステープルのクラウン部22の下側に針受け支持部材4の針支持部17を入れ、クラウン部22の両側の下部を針支持部17で支持する。次に、押圧用スライダ3の指掛け部14に人差し指の先端を掛けて押圧レバー10を下方に折り曲げる。これにより、針押し部11の押圧部16が外科用ステープルのクラウン部22の上部中央に係合する。さらに、指掛け部14に力を加えて押圧レバー10を下方に曲げると、外科用ステープルのクラウン部22は両側下部が針支持部17で支持された状態で、中央上部が押圧部16によって上から下方に押し込まれるので、図3(b)のようにU字状に折れ曲がって変形し、全体がM字状になって両側の脚部24は皮膚から抜き出される。このようにして外科用ステープル20を抜き出した後、図4に示すように上記押圧用スライダ3をバネ12に抗して後方にスライドさせると、外科用ステープル20は針押し部11の係合部15に係合し、取込開口部5から収納部6内に取り込まれ、さらに押圧用スライダ3の移動端まで送られる。上記押圧用スライダ3が移動端までスライドしたとき、図5のように押圧用スライダ3の係合部15の後面は最も手前にある係合凹部23aに対応する位置にあるように設定されているから、引き込まれた外科用ステープルは最も手前の係合凹部23aに係合して支持される。その後、押圧用スライダ3から力を抜いてバネ12のバネ力によって初期位置に復帰移動させる。押圧用スライダ3が原位置に戻っても、外科用ステープル20は1対の針受け部18に安定して支持され、また両針受け部18の鋸歯状に形成された歯と歯の間に形成された係合凹部23に係合しているので、戻り方向(前方)には移動できず、そのままの位置に保持される。  Next, the operation of the surgical staple remover 1 configured as described above will be described. First, themain body portion 2 is held with one hand, and as shown in FIG. 3 (a), theneedle support portion 17 of the needle receivingsupport member 4 is placed below thecrown portion 22 of the surgical staple with the wound wound. Lower portions on both sides of theportion 22 are supported by theneedle support portion 17. Next, the tip of the index finger is hung on thefinger hooking portion 14 of thepressing slider 3 and thepressing lever 10 is bent downward. Thereby, thepressing portion 16 of theneedle pressing portion 11 is engaged with the upper center of thecrown portion 22 of the surgical staple. Further, when thepressure lever 10 is bent downward by applying a force to thefinger hooking portion 14, thecrown portion 22 of the surgical staple is supported by theneedle support portion 17 on both sides, and the central upper portion is viewed from above by thepressing portion 16. Since it is pushed downward, it is bent and deformed into a U shape as shown in FIG. After thesurgical staple 20 has been extracted in this manner, as shown in FIG. 4, when thepressing slider 3 is slid backward against thespring 12, thesurgical staple 20 is engaged with the engaging portion of theneedle pushing portion 11. 15, is taken into the storage portion 6 from the take-in opening 5, and further sent to the moving end of thepressing slider 3. When thepressing slider 3 is slid to the moving end, the rear surface of the engagingportion 15 of thepressing slider 3 is set so as to be in a position corresponding to theengaging recess 23a that is closest to thepressing slider 3 as shown in FIG. Thus, the retracted surgical staple is engaged with and supported by the foremostengaging recess 23a. Thereafter, the force is removed from thepressing slider 3 to return to the initial position by the spring force of thespring 12. Even if thepressing slider 3 returns to the original position, thesurgical staple 20 is stably supported by the pair ofneedle receiving portions 18 and between the teeth formed in the serrated shape of the bothneedle receiving portions 18. Since it is engaged with the formed engagingrecess 23, it cannot move in the return direction (forward) and is held in its position.

次の外科用ステープル20も同様にして押圧用スライダ3の同じ操作によって抜針され、押圧用スライダ3の後方スライドによって取込開口部5から収納部6内に取り込まれる。そして、押圧用スライダ3が移動端に到達したときに、取り込まれた外科用ステープル20は最も手前の係合凹部23aまで押し込まれるので、この係合凹部23aに保持されていた前の外科用ステープル20は強制的に後方に押し出される。係合凹部23の後方には緩やかな傾斜が形成されているので、押された外科用ステープル20は円滑に後方に押し込まれる。隣り合う係合凹部23bの間隔は約ステープル1〜1.5本分の幅と略同じ程度になるように設定されているから、押し込まれた外科用ステープル20は次の係合凹部23bに係合して支持される。その後、押圧用スライダ3から力を抜いてバネ12のバネ力によって初期位置に復帰移動させると、上記2つの係合凹部23に係合した外科用ステープル20は、そのままの位置に保持される。以下、同様にして針受け支持部材4の針受け部18の係合凹部23には、抜針された外科用ステープルが順次に後方に並べられた状態で保持される。  Similarly, the nextsurgical staple 20 is pulled out by the same operation of thepressing slider 3 and is taken into the storage portion 6 from the take-in opening 5 by the rear slide of thepressing slider 3. When thepressing slider 3 reaches the moving end, the takensurgical staple 20 is pushed to the foremostengaging recess 23a, so that the previous surgical staple held in theengaging recess 23a is pushed. 20 is forcibly pushed backward. Since a gentle slope is formed behind the engagingrecess 23, the pressedsurgical staple 20 is smoothly pushed backward. Since the interval between adjacent engagingrecesses 23b is set to be approximately the same as the width of about 1 to 1.5 staples, the pushedsurgical staple 20 is engaged with the nextengaging recess 23b. It is supported together. Thereafter, when the force is removed from thepressing slider 3 and returned to the initial position by the spring force of thespring 12, thesurgical staple 20 engaged with the twoengaging recesses 23 is held in the same position. Hereinafter, similarly, the removed surgical staples are sequentially held rearwardly in theengagement recess 23 of theneedle receiving portion 18 of the needle receivingsupport member 4.

このようにして、最後の外科用ステープル20を最も手前の係合凹部23に保持したとき、すべての抜針された外科用ステープル20は針受け部18の係合凹部23に整然と並んだ状態で保持される。したがって、何本の外科用ステープルを抜いたかは、本体部2の横から目視によって数えることができる。  In this way, when the lastsurgical staple 20 is held in the foremost engagingrecess 23, all of the removedsurgical staples 20 are arranged in an orderly manner in the engagingrecess 23 of theneedle receiving portion 18. Retained. Therefore, how many surgical staples are pulled out can be counted visually from the side of themain body 2.

なお、収納部6の高さは、抜針された外科用ステープル20の高さよりも少しだけ大きくなるようにするのが好ましい。具体的には、収納部6の上面は、針受け部18に支持された外科用ステープル20よりもその厚み分より少し高くし、また収納部6の下面は、針受け部18に支持された外科用ステープル20の下端よりも僅かに低い程度に形成するのが好ましい。これにより、外科用ステープルリムーバ1を少し傾けたり、動かしたりしても、内部に保持された外科用ステープルは係合凹部23から外れにくく、針受け部18に支持された状態で良好に保持される。  In addition, it is preferable that the height of the storage portion 6 is slightly larger than the height of thesurgical staple 20 that has been removed. Specifically, the upper surface of the storage unit 6 is slightly higher than the thickness of thesurgical staple 20 supported by theneedle receiver 18, and the lower surface of the storage unit 6 is supported by theneedle receiver 18. Preferably, it is formed to be slightly lower than the lower end of thesurgical staple 20. Accordingly, even if the surgical staple remover 1 is slightly tilted or moved, the surgical staple held inside is hardly detached from theengagement recess 23 and is held well in a state of being supported by theneedle receiving portion 18. The

また、係合凹部23は必ずしも鋸歯状に形成されているものに限定されない。例えば、連続する波形でもよい。  Moreover, the engagement recessedpart 23 is not necessarily limited to what is formed in sawtooth shape. For example, a continuous waveform may be used.

さらに、本体部2又は針受け支持部材4の針受け部18に、10本、20本、30本毎に目安となるように色変えしたり、目盛りを表示したりすることにより、迅速かつ確実に計算できるようにしてもよい。  Further, theneedle holder 18 of themain body 2 or the needleholder support member 4 can be quickly and reliably changed in color so that it becomes a standard every ten, twenty or thirty, or a scale is displayed. It may be possible to calculate it.
