Abstract
Description
本発明は、医療用器具の改良、更に詳しくは、狭範囲の手術において切開部分近傍の施術スペースを広く確保することができ、かつ、着脱操作の使い勝手の良い狭範囲手術用開創器に関するものである。 The present invention relates to an improvement of a medical instrument, and more particularly, to a narrow-range surgical retractor which can ensure a wide operation space near an incision in narrow-range surgery and which is easy to use and remove. is there.
外科手術において切開部位を広げた状態で保持しておくためには、助手が横に立って鉤引きを行う必要があるが、バネ指（弾撥指）の手術のような切開範囲が狭い場合においては、助手の身体や鉤引きの器具が術者の邪魔になってしまい、作業性が悪いという問題がある。 In order to hold the incision site wide in the surgical operation, the assistant needs to stand sideways to perform a pulling operation, but in the case where the incision range is narrow like a spring finger (repelling finger) surgery In this case, the body of the assistant and the pulling tool become in the way of the operator, and there is a problem that the workability is bad.
そこで、従来、助手を必要としない開創器として、反発力を有する対向するアームの先端にブレードを備えた開創器が開示されている（例えば、特許文献１参照）。 Therefore, as a retractor that does not require an assistant, a retractor having a blade at the tip of an opposing arm having a repulsive force has been disclosed (see, for example, Patent Document 1).
しかしながら、この＜特許文献１＞の開創器は、１箇所で折曲されて対向部分が直線状であるアーム形状しか開示されていないことから、かかる構造から推察するに、アームからブレードが垂下されていると、アームの直線部分が切開部分近傍に存在してしまい、施術スペースが十分に確保できず、施術作業の際に術者が使用する他の器具がアームに接触するおそれがあり、接触しないように余計な注意が必要となり、非常に煩わしいという不満がある。 However, since the retractor of <Patent Document 1> discloses only an arm shape which is bent at one place and the opposing portion is linear, it is inferred from such a structure that the blade is dropped from the arm. If this happens, the straight part of the arm will be near the incision and there is a risk that the treatment space can not be secured enough and other tools used by the operator may come into contact with the arm during the treatment operation. There is a dissatisfaction that it takes extra care not to do so and it is very annoying.
また、アームが直線状である場合は、皮膚の起伏においてアームの一部が皮膚に接触すると、この接点がテコの支点となってしまい、不安定になってこの開創器が動いてしまったり、ブレードが浮き上がって切開部分から抜けてしまうおそれもある。 Also, if the arm is straight, if a part of the arm contacts the skin during skin ups and downs, this contact will be the fulcrum fulcrum, becoming unstable and this retractor may move, There is also a possibility that the blade may come up and come out of the incision.
更にまた、直線状アームと皮膚との間には十分な隙間がないため、着脱操作を行うためにアームを摘むとき、術者の摘んだ指先が切開部分近傍の皮膚を不必要に押圧してしまい、出血や痛みを与えてしまうおそれがある。 Furthermore, since there is not a sufficient space between the linear arm and the skin, when the arm is pinched to perform the attaching / detaching operation, the finger pinched by the operator unnecessarily presses the skin in the vicinity of the incision. It may cause bleeding and pain.
この点を改善するためか、同文献の実施形態には、操作性を向上させるために、別部材であるリング状の操作摘み部を付設するものが開示されているが、溶着加工等によって製造コストが増大してしまうし、使用を重ねるうちにこの溶着部分の破断してしまうおそれがある。 Although it is disclosed to attach a ring-shaped operation knob which is a separate member in the embodiment of the same document in order to improve the operability, in order to improve this point, it is manufactured by welding or the like. The cost increases and there is a risk that the welded portion may break while being used repeatedly.
更に、アームが直線状である場合、リング状の操作摘み部を機能させるためには、同文献に図示されているとおり、不可避的にアーム上におけるブレードの反対側に起立して付設せざるを得ず、こうしてブレードの反対側に操作摘み部が突出すると、操作摘み部が施術の際に邪魔になるという問題もある。しかも、操作摘み部を摘んだ場合には、アームを軸回転方向にねじる力がかかるため、アームが弾性変形してブレードの下端部同士が外側にハの字型に離れてしまい、切開部分へのブレードの挿入を円滑に行うことができないおそれがある。かと言って、軸のねじれを防止するためにアームの剛性を大きくすると、ブレードを閉じる際に必要な力が大きくなって操作性が悪くなるとともに、弾性復元力が強くなり過ぎて、切開部分を必要以上に開いてしまうという問題もある。 Furthermore, in the case where the arm is linear, in order to make the ring-shaped operation control part function, as shown in the same document, it is inevitable to be erected and attached to the opposite side of the blade on the arm. If the control knob protrudes to the opposite side of the blade in this way, there is a problem that the control knob becomes an obstacle during the operation. In addition, when the operation knob is pinched, a force is applied to twist the arm in the axial rotation direction, so the arms are elastically deformed and the lower ends of the blades are separated outward in a V shape, leading to the incision portion There is a risk that the insertion of the blade can not be performed smoothly. In other words, if the rigidity of the arm is increased to prevent the twisting of the shaft, the force required to close the blade will increase and the operability will deteriorate, and the elastic restoring force will become too strong. There is also a problem that it opens more than necessary.
本発明は、従来の開創器に上記のような問題があったことに鑑みて為されたものであり、その目的とするところは、狭範囲の手術において切開部分近傍の施術スペースを広く確保することができ、かつ、着脱操作の使い勝手の良い狭範囲手術用開創器を提供することにある。 The present invention has been made in view of the problems as described above in the conventional retractor, and the purpose of the present invention is to secure a wide operation space in the vicinity of the incision in narrow-range surgery. It is an object of the present invention to provide an easy-to-use narrow-range surgical retractor that can be used and removed.

From the above, industrial use value is great.
本発明の実施形態を図１から図１１に基づいて説明する。図１中、符号１で指示するものは線バネであり、符号２で指示するものはツマミ部である。また、符号３で指示するものは板体である。なお、図２から図６は本発明の開創器の六面図である。 Embodiments of the present invention will be described based on FIGS. 1 to 11. In FIG. 1, the one designated by the reference numeral 1 is a wire spring, and the one designated by the reference numeral 2 is a knob portion. Moreover, what is designated by the code 3 is a plate. 2 to 6 are six views of the retractor according to the present invention.
本発明の狭範囲手術用開創器の構成について以下に説明する。まず、弾性線材からなる線バネ１を、凸端11を折曲する。本実施形態では、弾性線材として金属（例えば、防錆ステンレス）を採用し、凸端11を略Ｕ字状に折曲したものが好ましい。丸みを帯びていることにより、安全性が高いとともに、反復する弾性変形に対しても材料疲労や局部的な負荷による塑性変形や脆性破壊などが起こり難く形態安定性が高い。 The configuration of the narrow-range surgical retractor according to the present invention will be described below. First, the convex end 11 of the wire spring 1 made of an elastic wire is bent. In the present embodiment, it is preferable to use a metal (for example, rustproof stainless steel) as the elastic wire and to bend the convex end 11 into a substantially U shape. By being rounded, safety is high, and plastic deformation or brittle fracture due to material fatigue or local load does not easily occur even in repeated elastic deformation, and the form stability is high.
また、前記凸端11の両側から対称的に延成される腕部12の中間にそれぞれカーブ12ａを形成する。このカーブ12ａは、所定範囲を緩やかに曲げて角度を付与するものや、一部分を折曲して角度を付与することができ、側面視において約１２０〜１７０°の範囲が好ましい。こうすることにより、線バネ１の凸端11を支点、ツマミ部２を力点、板体３を作用点として、線バネ１を撓曲（弾性変形）させる場合に、これら３点のズレによって、板体３の開閉軌道を同一平面の円弧軌道上から偏倚させることができ、板体３・３の対向面同士をなるべく平行に近い角度で移動させて安定的に当接させることができる。 In addition, a curve 12 a is formed in the middle of the arm portion 12 extended symmetrically from both sides of the convex end 11. The curve 12a may be formed by gently bending a predetermined range to give an angle, or partially bending it to give an angle, and a range of about 120 to 170 degrees in a side view is preferable. By doing this, when the wire spring 1 is bent (elastically deformed) with the convex end 11 of the wire spring 1 as a fulcrum, the knob portion 2 as a force point, and the plate 3 as an action point, The open / close trajectory of the plate 3 can be deviated from the same circular arc trajectory, and the facing surfaces of the plates 3 and 3 can be moved at an angle as close as possible parallel to each other to be stably in contact.
そして、この線バネ１の各先端13には、線材を折曲してなる左右一対のツマミ部２をそれぞれ外側に膨出して対称的に配設する。こうすることによって、この膨出部分に施術スペースを作出することができる。 Then, at each end 13 of the wire spring 1, a pair of left and right knobs 2 formed by bending a wire are respectively expanded outward and disposed symmetrically. By doing this, a treatment space can be created in this bulging portion.
また、本実施形態では、ツマミ部２をコの字型またはＵ字型の線材にすることができ、術者が摘みやすく、操作性を向上させることができる。 Further, in the present embodiment, the knob portion 2 can be formed into a U-shaped or U-shaped wire, so that the operator can easily pick and improve the operability.
次に、これら各ツマミ部２の基端部21と前記線バネ１の先端13とを固定する。本実施形態では、線バネ１とツマミ部２とを、同一線材により一体成形することができ、加工を簡素化して製造コストを下げることができる。 Next, the base end 21 of each of the knobs 2 and the tip 13 of the wire spring 1 are fixed. In the present embodiment, the wire spring 1 and the knob portion 2 can be integrally formed of the same wire, so that the processing can be simplified and the manufacturing cost can be reduced.
そして、当該ツマミ部２の先端部22と板体３の側縁31における上角部31ａとを固定して、当該板体３が垂下方向に拡開状態で支持する。このようにツマミ部２と板体３とは端部同士で固定することにより、両部材をできるだけ離すことができ、板体３の切開部分への挿入に対して、ツマミ部２の干渉を最小限にすることができる。 Then, the distal end portion 22 of the knob portion 2 and the upper corner portion 31a of the side edge 31 of the plate 3 are fixed, and the plate 3 is supported in the drooping direction in the expanded state. Thus, by fixing the knob portion 2 and the plate 3 at the end portions, both members can be separated as much as possible, and the interference of the knob portion 2 with the insertion into the cut portion of the plate 3 is minimized. Can be limited.
本実施形態では、図７に示すように、板体３の下端部32に外側に末広がりな係止部を形成することができ、切開部分から抜け難く、かつ、内部奥側に確実に係止させることができる。更に、この際、ツマミ部２と板体３とのなす角度を鋭角（好ましくは約８５°）にすることができ、板体３が内部で広がって係止力を上げることができる。 In the present embodiment, as shown in FIG. 7, an outwardly extending locking portion can be formed at the lower end portion 32 of the plate 3, so that it is difficult to come off from the cut portion and reliably locked to the inner back side. It can be done. Further, at this time, the angle formed between the knob portion 2 and the plate 3 can be made acute (preferably about 85 °), and the plate 3 can be spread inside to increase the locking force.
こうして開創器が構成されることによって、前記ツマミ部２が指腹で摘まれるとき、線バネ１が弾性変形して前記板体３・３の対向面同士が当接可能である（図８参照）。 Thus, by configuring the retractor, when the knob 2 is pinched by the finger pad, the wire spring 1 is elastically deformed so that the opposing surfaces of the plates 3 can contact each other (see FIG. 8). ).
更に、前記線バネ１本体およびツマミ部２本体は、側面視において線バネ１の凸端11および板体３の上角部31ａを結ぶ直線（図中の一点鎖線）を挟んで板体３の反対側に位置させることもできる（図９参照）。こうすることによって、患者の皮膚との間にスペースができるため、ツマミ部２を指腹で摘んで着脱操作する際に、術者の指先が皮膚を無理に押圧するのを防止することができる。本実施形態では、ツマミ部２の側方に折曲部23を形成することができ、このスペースを更に大きくすることができる。 Furthermore, the wire spring 1 main body and the knob portion 2 main body of the plate 3 are sandwiching a straight line (one-dot chain line in the figure) connecting the convex end 11 of the wire spring 1 and the upper corner 31a of the plate 3 in side view. It can also be located on the opposite side (see FIG. 9). By doing this, since there is a space between it and the patient's skin, it is possible to prevent the operator's fingertips from forcibly pressing the skin when the knob portion 2 is pinched by the finger pad and the detachment operation is performed. . In the present embodiment, the bending portion 23 can be formed on the side of the knob portion 2, and this space can be further enlarged.
なお、この際、図１０に示すように、側面視において線バネ１の凸端11および板体３の上角部31ａを結ぶ直線（図中の一点鎖線）と板体３の側縁31とのなす角度αを９０°よりも大きくすることによって、切開部分への着脱操作時の使い勝手をより向上させることができる。 At this time, as shown in FIG. 10, a straight line (dot and dash line in the figure) connecting the convex end 11 of the wire spring 1 and the upper corner 31a of the plate 3 in side view and the side edge 31 of the plate 3 By setting the angle α to be larger than 90 °, usability at the time of attachment / detachment operation to the incision portion can be further improved.
以上のように構成された本発明の開創器は、ツマミ部２・２を摘んで板体３・３の対向面同士を当接させ、この当接状態の板体３・３を切開部分Ｐに挿入した後、弾性復元により拡開させることによって、切開部分Ｐの近傍に十分な施術スペースを形成しつつ、切開部分Ｐを広げた状態で保持することができる（図１１参照）。 In the retractor according to the present invention configured as described above, the knobs 2 and 2 are pinched to bring the opposing surfaces of the plates 3 and 3 into contact with each other, and the plates 3 and 3 in this contact state are cut out P After the insertion, the elastic portion can be expanded to thereby maintain the incision P in a spread state while forming a sufficient treatment space in the vicinity of the incision P (see FIG. 11).
本発明は、概ね上記のように構成されるが、図示の実施形態に限定されるものでは決してなく、「特許請求の範囲」の記載内において種々の変更が可能であって、例えば、線バネ１の凸端11の形状は略Ｕ字状に限らず、Ｖ字状やコの字状、Ｗ字状などを採用することができる。 Although the present invention is generally configured as described above, it is by no means limited to the illustrated embodiment, and various modifications can be made within the scope of the claims, for example, a wire spring The shape of the convex end 11 of 1 is not limited to a substantially U-shape, and a V-shape, a U-shape, a W-shape, or the like can be adopted.
また、線バネ１、ツマミ部２および板体３の結合は一体成形や、溶接、貼着、接着剤などの手段を採用することができる。 Further, the connection of the wire spring 1, the knob portion 2 and the plate 3 can be carried out by means of integral molding, welding, sticking, an adhesive or the like.
更にまた、線バネ１およびツマミ部２の使用材料は、金属に限らず他の弾性材料を採用することができるし、板体３も大きさや形状などを設計変更することができ、これら何れのものも本発明の技術的範囲に属する。 Furthermore, the material used for the wire spring 1 and the knob portion 2 is not limited to metal, and other elastic materials can be adopted, and the plate 3 can also be designed and changed in size, shape, etc. Those also fall within the technical scope of the present invention.
