【考案の詳細な説明】
（産業上の利用分野）
本考案は、外科手術時に発生する出血に対し、
すぐれた凝血、治癒効果を発揮する生体吸収性ガ
ーゼに関する。[Detailed description of the invention] (Field of industrial application) This invention is designed to prevent bleeding that occurs during surgical operations.
This invention relates to bioabsorbable gauze that exhibits excellent blood clotting and healing effects.
（従来技術）
従来、この種の用途にはセルロース系繊維で織

の吸収により糊状になり手術中に手袋その他に付
着する等の問題がある。 However, these have poor adhesion to the affected area, and in particular, the former type cannot be left in the body after surgery because it is not bioabsorbable, and the latter type also has a tendency to absorb body fluids, blood, etc. There are problems such as it becoming glue-like and adhering to gloves and other surfaces during surgery.
一方、吸収性材料による止血材としては特公昭

用しにくいなどの欠点を有する。 On the other hand, as a hemostat material made of absorbable material,
No. 58-29105 discloses a surgical felt made of polyglycolic acid fibers, which is rigid because it is manufactured by heat molding, and has a dense surface structure that makes it difficult to adhere to the affected area.
It has drawbacks such as being highly irritating to the affected area and difficult to use because the molded product is so strong that it cannot be torn off by hand during surgery.
（考案が解決しようとする問題点）
本考案は、上記の欠点を解消したもので手術時
および手術後の出血部に対して局所的に密着し、

不織布で構成したことに特徴を有する生体吸収性
外科用ガーゼに関する。(Means for Solving the Problem) However, the present invention is a bioabsorbable fabric that is characterized by being constructed by overlapping a knitted or woven fabric made of bioabsorbable synthetic polymer fibers and a nonwoven fabric made of the same material. It is a gauze for sexual surgery, and as an example of its specific structure, it has a sandwich structure in which non-woven fabric is knitted on both sides and woven fabric is overlapped, the thickness of the non-woven fabric is 0.2 to 2.0 mm, and the density is 0.2 to 2.0 mm. of
This invention relates to a bioabsorbable surgical gauze characterized by having a weight in the range of 20 to 120 g/m 2 and being made of a nonwoven fabric made by needle-punching bioabsorbable synthetic polymer fibers.

る。 That is, the present invention uses synthetic polymers such as polyglycolic acid, polylactide, polydioxanone, and polycaprolactone as raw materials, and can be used alone or in copolymerized form. Polyglycolic acid has particularly good absorbability. Spun to a fineness of 2 to 6 deniers, or knitted, woven, or non-woven fabrics that have been left to stand for a long time or have been heat-treated to become soft and deteriorated can be suitably used.
また、その編、織組織はシングル、ダブル等の
丸編、或いはトリコツト等の経編，平、綾、朱子
等の織地等任意であるが、伸縮性、耳部のほつ

パンチによるものが好適である。 In addition, the knitting and weaving structure can be arbitrary, such as circular knitting such as single or double knitting, warp knitting such as tricotto, or woven fabrics such as plain, twill, and satin, but there are problems such as elasticity, fraying of the edges, curling, etc. Considering this, warp knitting is ideal. Further, the nonwoven fabric to be overlapped with this is preferably made by needle punching.
また、編、織物、不織布の編、織目は完全に目

うすく、また、上限を越えると、血液の透過、吸
収性が極端に悪くなり患部から外れる欠点を生ず
る。 In addition, the knitting, woven fabric, and nonwoven fabric should not be completely closed, but should have porous regular voids. Thickness from 0.2 to m2 density
It is desirable that it be within the range of 2.0m/m. If it is below the lower limit, the thickness and voids will be too large and the hemostatic effect will be poor, and if it exceeds the upper limit, blood permeability and absorption will be extremely poor, resulting in the problem that it will come off the affected area.
（作用） 即ち、本考案は前記の如き構成であるため、 (a) 出血部への密着性がよい。(effect) That is, since the present invention has the above-mentioned configuration, (a) Good adhesion to bleeding areas.
(b) 血液、体液の量にあわせて重ね枚数を変更し
て対応できる。(b) The number of layers can be changed according to the amount of blood and body fluids.
(c) 不織布の適用により伸縮性、編織目を任意に
コントロールすることができる。(c) By applying nonwoven fabric, stretchability and weave can be controlled arbitrarily.
(d) 特に、熱処理等によりフレキシブルで柔らか

(e) 血液、胆汁等が排出、吸収され易い組織構造
である。(e) It has a tissue structure that allows blood, bile, etc. to be easily excreted and absorbed.
(f) 体内への分解吸収速度を適宜にコントロール
することができる。(f) The rate of decomposition and absorption into the body can be appropriately controlled.
(g) 術後の撤去が必要なく、そのまま放置し、機
能を必要としなくなつたとき生体に速やかに吸
収され無害である。(g) There is no need to remove it after surgery; it is left as is, and when its function is no longer needed, it is quickly absorbed by the living body and is harmless.
(h) 熱処理により柔軟、劣化してあるので適用時
任意の形状大きさに手で引きちぎることができ
る。(h) It has been softened and deteriorated by heat treatment, so it can be torn by hand into any shape or size when applied.
等、多大の作用、効果を有する。It has many functions and effects.
以下、実施例を挙げて説明する。 Examples will be described below.

ような構成とした。(Example) Polyglycolic acid having an intrinsic viscosity of 1.2 was melt-spun to obtain a yarn of 2.5 denier per filament with 18 filaments, which was stretched 4 times at 45° C. to improve orientation. This yarn is knitted with a density of 50g/
The tape 1 had a width of 5 cm and a width of 5 cm. On the other hand, the same material was needle punched to a thickness of 1.0m/m and a density of
A nonwoven fabric 2 of 100 g/m 2 was obtained. Both of these were treated in an autoclave at 121℃ for 30 minutes to make them soft and
Strong enough to tear by hand, i.e. tear strength 150g
This was adjusted to a certain degree, and the two layers were overlapped to form a structure as shown in FIG.
尚、第２図には前記の不織布２を真中にし、そ
の上下を編地テープ１で挟んでサンドイツチ状に
構成した例を示した。 FIG. 2 shows an example in which the nonwoven fabric 2 is placed in the middle and the upper and lower sides are sandwiched between knitted fabric tapes 1 to form a sandwich-like structure.

ことがなくそのままの状態を維持した。 When the hemostatic gauze obtained as described above was applied to the resected part of the liver of a white rabbit, it immediately had a hemostatic effect on the gradual bleeding.In particular, when the gauze was brought into contact to cover the part, it quickly adhered as blood was absorbed. It was fixed and remained in that state without floating or coming off.
これの術後の経過もよく、通常この種の手術に
おいて発生する細菌汚染もみられなかつた。 The postoperative course was good, and there was no bacterial contamination that usually occurs in this type of surgery.
尚、術後10日目に切開し、該部を観察したとこ

い。(Effects) As described above, the present invention works well during surgical operations, especially because blood, etc. diffuses into the gaps in the knitting and weaving, and coagulates quickly when the gaps are filled. It is thought that. Note that the coagulated blood decomposes after a few days and is absorbed into the body without leaving any damage.

である。 The gauze of this invention is particularly effective for gradual bleeding that cannot be stopped by coagulation methods such as electrocautery, and can be applied in layers or more depending on the situation, and can be torn off by hand. This makes it possible to quickly respond to emergencies during surgery.
又、血管吻合、例えば端側吻合、端々吻合の場
合の継目に対し、タスキ掛け、あるいはその周囲
に平行に巻き付け、止血する場合にも好適に適用
可能である。 It can also be suitably applied to a joint in a blood vessel anastomosis, such as an end-to-end anastomosis or an end-to-end anastomosis, by wrapping it with a sash or wrapping it in parallel around the joint to stop bleeding.
即ち、実質臓器よりの出血の止血に対し効果的
で、外科手術一般、例えば、脳外科、婦人科等侵
襲を加える患者に利用することが可能であるが、
特に肝臓、腎臓手術、血友病等の治療に好適に用
いることができる。 That is, it is effective in stopping bleeding from parenchymal organs, and can be used in general surgical procedures, such as neurosurgery, gynecology, and other invasive patients.
In particular, it can be suitably used for liver and kidney surgery, and for the treatment of hemophilia.
特に、肝臓手術においては、従来、患部より排
