本発明の実施の形態を以下に説明する。
従来、縫合針の材質は、錆びない、折れない等の基本的な必要性から、主としてオーステナイト系のステンレスが用いられている。また精密加工と表面研磨を要することから針穴部が複雑な形状のものは作られていなかった。
しかし、最近ナノテクノロジーといわれる技術が発展し、超微細分野への応用が図られており、この中で金属の超微細精密加工も容易となってきている。
本発明はこれらの技術を背景として、精密加工を施し曲線部分を基本としたより使い易い針穴の形状の縫合針を製作し、提供する。
以下、図に基づき実施の形態の詳細を説明する。
Embodiments of the present invention will be described below.
Conventionally, austenitic stainless steel has been mainly used as a material for suture needles because of the basic necessity of not rusting or breaking. Moreover, since the precision processing and surface polishing were required, the thing with a complicated needle hole part was not made.
Recently, however, a technology called nanotechnology has been developed and applied to the ultrafine field, and ultrafine precision processing of metals has become easier.
With the background of these techniques, the present invention produces and provides a suture needle in the shape of a needle hole that is precision-processed and is easier to use based on curved portions.
Hereinafter, details of the embodiment will be described with reference to the drawings.

図示したように針体基部２の糸の掛止部３の構造は、針体腹部に横断方向の開口切欠溝５を有し、かつ同溝は入口部が狭く内部が広く形成され、そして横断方向の開口切欠溝５の後部壁体７が、開口切欠溝５の前部壁体６よりも低く形成されている。そして、前記横断方向の開口切欠溝５が、その後部壁面９及び前部壁面１６が半円形面又は半楕円形面に形成されている。
FIG. 1 is an external view of a standard suture needle of the present invention.
(A) is a top view, (B) is a front view, and (C) is a side view.
In the figure, 1 is a suture needle, 2 is a needle body base, 3 is a latching portion, 4 is an opening notch groove entrance,
5 is an opening notch, 6 is a front wall, 6 'is a front wall end, 7 is a rear wall, 7' is a rear wall end, 8 is inside the opening notch, 9 is a rear wall, 10 is a rear end of the suture needle, 11 is a thread, and 16 is a front wall surface.
As shown in the drawing, the structure of the thread hooking portion 3 of the needle body base 2 has an opening notch groove 5 in the transverse direction in the needle body abdomen, and the groove has a narrow inlet portion and a wide inside, and The rear wall 7 of the opening notch groove 5 in the direction is formed lower than the front wall 6 of the opening notch groove 5. In the transverse opening notch groove 5, the rear wall surface 9 and the front wall surface 16 are formed in a semicircular or semi-elliptical surface.
操作は、掛止する糸１１の側面を開口切欠溝入口４に斜め横から導入する、
この時、開口切欠溝５の隙間は糸１１の直径に比し狭いが、前記開口切欠溝入口４の上下の部分は薄く、かつ材質は例えば前記オーステナイト系のステンレスであるから弾力性を有している。
また糸１１自体も特に繊維状のものは弾力性を有しており、かつ、前記開口切欠溝５がバネ溝を構成しているので、糸の導入に従って拡大し、また、糸の通過後は狭小に復元するため、糸を掛止し易くまた抜けにくい。
さらに、開口切欠溝５を構成する前部壁体６及び後部壁体７の前部壁体端部６’及び後部壁体端部７’並びに、後部壁面９と前部壁面１６は、半円形面又は半楕円形面に形成されており、

The operation introduces the side surface of the thread 11 to be hooked into the opening notch groove inlet 4 from the oblique side,
At this time, the gap of the opening notch groove 5 is narrower than the diameter of the thread 11, but the upper and lower portions of the opening notch groove inlet 4 are thin and the material is, for example, the austenitic stainless steel, so that it has elasticity. ing.
Further, the thread 11 itself is particularly fibrous and has elasticity, and the opening notch groove 5 constitutes a spring groove, so that it expands as the thread is introduced, and after the thread has passed, Since the thread is restored to a small size, it is easy to hook the thread and to remove it easily.
Further, the front wall end 6 ′ and the rear wall end 7 ′ of the front wall body 6 and the rear wall body 7 constituting the opening notch groove 5, and the rear wall surface 9 and the front wall surface 16 are semicircular. Formed into a surface or semi-elliptical surface,
Since the thread 11 is introduced along the curved surface, the thread 11 is hooked to the rear wall surface 9 through the opening notch groove 8 in the latching part 3 of the needle body base 2 without being caught by the opening notch groove 5. And since it pulls out outside across the suture needle rear end 10 which forms a curved surface, it is possible to prevent the thread 11 from being cut by the corners of the opening notch groove 5.
従って、貫通型のように糸先を針穴に通さなくてもよいため、作業は誰でも容易に行うことができる。
また、前述したように前記針体の開口切欠溝入口４は前方の位置が後方より高く、また開口切欠溝５は曲線状に形成されているため、被縫合物の組織を傷つけることはない。
Accordingly, since it is not necessary to pass the thread tip through the needle hole as in the case of the penetrating type, anyone can easily perform the operation.
Further, as described above, the opening notch groove inlet 4 of the needle body has a front position higher than the rear, and the opening notch groove 5 is formed in a curved shape, so that the tissue of the sutured object is not damaged.

As described above, the side surface of the thread 11 to be hooked is introduced into the opening notch groove inlet 4 obliquely from the side. The thread 11 is introduced along the curved surface of the opening notch groove 5. The hook 3 passes through the opening notch groove 8 and reaches the rear wall 9 without being caught in the opening notch 5. And since it pulls out outside across the suture needle rear end 10 which forms a curved surface, it is possible to prevent the thread 11 from being cut by the corners of the opening notch groove 5.
そして前記糸１１を外部に引き出す際、前記立設柱状部１２をなすくびれ部１３に１〜数回巻き付ける。
上記の巻き付けにより、糸１１が前記後部壁面９の掛止箇所からずり落ちる可能性は少なくなる（図２（ハ）図参照）。
前述したように、糸１１の中間部を斜め横から導入でき、貫通型のように糸先を針穴に通さなくてもよく、かつ糸は柱状部に巻き付けられるため抜けにくく、作業を容易にまた確実に行うことができる。
この型は医療手術用縫合針として用いた場合、従来の弾機穴による糸の切断を避け、かつ糸抜けを防止することができる。
And when pulling out the said thread | yarn 11 outside, it winds around the constriction part 13 which makes the said standing columnar part 12 1 to several times.
By the winding described above, the possibility that the thread 11 slips from the hooking portion of the rear wall surface 9 is reduced (see FIG. 2 (c)).
As described above, the middle portion of the thread 11 can be introduced obliquely from the side, and the thread tip does not have to be passed through the needle hole as in the case of the penetrating type. Moreover, it can be performed reliably.
When this type is used as a suture needle for medical surgery, it is possible to avoid thread breakage by a conventional bullet hole and to prevent thread dropout.
図３は本発明の糸巻き部粗目加工型の縫合針の外観図で、
（イ）は上面図、（ロ）は正面図、（ハ）は側面図を示す。
図において１４は粗目の加工を示す。
糸の導入、針穴部の基本構造及び、糸巻き部に巻き付けるまでの過程は前記図２の糸巻き型縫合針と同様であるから省略する。
そして、前記図２と異なる点は、前記柱状形をなすくびれ部１３の表面に、掛止した糸の滑りを防止するため凹凸又は筋状の粗目の加工１４を施こしてあるところである。この粗目の加工により巻き付けられた糸は、よりずり落ちる可能性を少なくすることができる。
FIG. 3 is an external view of the suture thread of the thread winding portion coarse-grained type of the present invention.

図において１５はクッションを示す。
糸の導入、針穴部の基本構造、及び糸巻き部に巻き付けるまでの過程は前記図３の糸巻き型縫合針と同様であるから省略する。
そして、前記図３と異なる点は、前記柱状形をなすくびれ部１３に、掛止した糸１１の滑りを防止するためのクッション１５を配設したところである。
FIG. 4 is an external view of the suture winding cushion type suture needle of the present invention,

針体基部２の糸の掛止部３の構造が、針体腹部に横断方向の開口切欠溝５を有し、かつ同開口切欠溝入口４は狭く内部が広く形成されている。
そして開口切欠溝５を構成する前部壁体端部６’及び後部壁体端部７’並びに前部壁面１６及び後部壁面９は、半円形面又は半楕円形面に形成されてなる。
まず、掛止する糸１１の側面を開口切欠溝入り口４より導入する。
この時、開口切欠溝入口４は糸１１の直径に比し狭いが、糸１１自体は特に繊維状のものは弾力性を有している。
従って、前記糸１１を導入すると、開口切欠溝５に沿って糸１１の径は縮小しながら通過し、開口切欠溝内部８に至ると弾力により再び元の径に戻る。
そして掛止部３の後部壁体９に至った糸１１は、外部に繰り出される（図５（ハ）図参照）。
前述したように、糸１１の側面（中間部）を横から導入すればよく、貫通型のように糸先を針穴に通さなくてもよいため、作業は誰でも容易に行うことができる。また、簡単な形状であるため、製作が容易であり、廉価にすることができる。
FIG. 5 is an external view of the weft insertion type suture needle of the present invention.
(A) is a top view, (B) is a front view, and (C) is a side view.
In the figure, reference numeral 16 denotes a front wall surface.
The structure of the thread hooking portion 3 of the needle base 2 has an opening notch groove 5 in the transverse direction at the needle body abdomen, and the opening notch groove inlet 4 is narrow and wide inside.
The front wall end 6 ′ and the rear wall end 7 ′, the front wall 16 and the rear wall 9 constituting the opening notch groove 5 are formed in a semicircular or semi-elliptical surface.
First, the side surface of the thread 11 to be hooked is introduced from the opening notch groove entrance 4.
At this time, the opening notch groove entrance 4 is narrower than the diameter of the thread 11, but the thread 11 itself is particularly fibrous and has elasticity.
Therefore, when the yarn 11 is introduced, the diameter of the yarn 11 passes along the opening notch groove 5 while being reduced, and when it reaches the inside 8 of the opening notch groove, it returns to the original diameter due to elasticity.
And the thread | yarn 11 which reached the rear part wall body 9 of the latching | locking part 3 is drawn | fed out outside (refer FIG.5 (c) figure).
As described above, the side surface (intermediate portion) of the thread 11 may be introduced from the side, and the thread tip does not have to be passed through the needle hole as in the case of the penetrating type. Therefore, anyone can easily perform the operation. Moreover, since it is a simple shape, manufacture is easy and it can be made inexpensive.

図において１６は前部壁面、１７は傾斜溝を示す。
開口切欠溝入口４は、図のように針体１の腹部前方内へ進入する傾斜角を有する傾斜溝１７が設けられてなる。
掛止する糸１１の側面を開口切欠溝入口４より導入する。
この時、開口切欠溝入口４は糸１１の直径に比し狭いが、糸１１自体は特に繊維状のものは弾力性を有している。
従って、前記糸１１を開口切欠溝入口４から導入すると、以降傾斜溝１７に沿って糸１１の径は縮小しながら通過し、開口切欠溝内部８に至ると弾力により再び元の径に戻る。
そして、掛止部３の後部壁体９に至った糸１１は、外部に繰り出される（図６（ハ）図参照）。
この型の縫合針は前記図５にくらべて、開口切欠溝の懐が深いため、容易に糸が外れない。
そして、この傾斜溝１７は、前記図１の標準型の縫合針、及び前記図２、図３、図４に示した後部壁体端部６’がオーバーハングして形成されている縫合針に適用してもよい。
FIG. 6 is an external view of an oblique weft insertion type suture needle,
(A) is a top view, (B) is a front view, and (C) is a side view.
In the figure, 16 is a front wall surface, and 17 is an inclined groove.
The opening notch groove inlet 4 is provided with an inclined groove 17 having an inclination angle to enter the front of the abdomen of the needle body 1 as shown in the figure.
The side surface of the thread 11 to be hooked is introduced from the opening notch groove inlet 4.
At this time, the opening notch groove entrance 4 is narrower than the diameter of the thread 11, but the thread 11 itself is particularly fibrous and has elasticity.
Therefore, when the thread 11 is introduced from the opening notch groove inlet 4, the diameter of the thread 11 passes along the inclined groove 17 while being reduced, and when the thread 11 reaches the inside 8 of the opening notch groove, it returns to the original diameter again due to elasticity.
And the thread | yarn 11 which reached the rear part wall body 9 of the latching | locking part 3 is drawn | fed out outside (refer FIG.6 (c) figure).
In this type of suture needle, the thread is not easily removed because the opening notch groove is deeper than in FIG.
The inclined groove 17 is formed on the standard suture needle shown in FIG. 1 and the suture needle formed by overhanging the rear wall body end portion 6 ′ shown in FIGS. You may apply.
なお、縫合針の形状は、直針、湾曲針等があり、縫い糸は繊維糸又は医療用の金属糸や可溶糸等がある。
大きさは、例えば、標準型の直針の長さは４０〜６０ｍｍ、太さ（直径）は０．３〜１ｍｍφ、糸の掛止部の径は０．１〜０．７ｍｍφ、糸の太さは０．０５〜０．６ｍｍφ等で、使用種別に応じて、大小の縫合針及び糸が選択される。
The shape of the suture needle includes a straight needle and a curved needle, and the sewing thread includes a fiber thread, a medical metal thread, a soluble thread, and the like.
For example, the length of the standard straight needle is 40 to 60 mm, the thickness (diameter) is 0.3 to 1 mmφ, the diameter of the hooking portion of the yarn is 0.1 to 0.7 mmφ, and the thickness of the yarn The size is 0.05 to 0.6 mmφ, and large and small suture needles and threads are selected according to the type of use.
