(Prior Art and its Problems) Various proposals have been made in the past as methods for storing medical suture systems having a length of about 40 to 75 am.

Some typical examples are: ■ Make a bundle of about 10 pieces, fold them in half or three, tie the folded center part with a thick string, and store it in a transparent film bag; ■ Have a spiral groove. Storage knife 6 (411 Kosho 42-17) inside the molded sheet
(See No. 145), ■ Something like folding the suture thread several times in a figure 8 shape and storing it between pieces of paper, etc. (α)
With the storage method (2) and (2), it is not possible to take out the suture threads one by one from the end, and there is a risk of tangles or bends during packaging and storage. Problems such as not being suitable for storage were pointed out.

Purpose of the Invention Therefore, the present invention provides a method for packaging and storing all medical suture threads (threads cut to a fixed length) without bending them at acute angles, protecting them from damage, and making it easy to take out the suture threads when the package is opened. Tbe (a medical suture storage container configured so that the thread ends can be sprayed out and the suture threads can be taken out smoothly one by one from the end without tangling, bending or damaging the suture threads) This is what we are trying to provide.

The present invention provides a mounting part on which a medical suture system is folded at least once and placed thereon, and a cover that is integrally provided with this mounting part via a folding part and covers the mounting part from both sides together with the suture thread. A mount main body having a wrapper part, and a mount head part that is integrally provided in the mounting part of the mount main body and has a slot for guiding and inserting one end of the suture to be placed, and is tearable and removable during use. Then, a tearing means is provided between the mounting part of the mount and the head part so that the head part can be removed, and a tearing means is provided between the mounting part of the mount and the head part, and a tearing means is provided between the mounting part and the head part to remove the suture thread at the part of the mounting part corresponding to each folded part of the mounted suture thread. At least one hooking piece for hanging the folded part of the suture is provided so that the folded part can be supported even when the suture is pulled out, and the tip of the suture is attached to the mount head part. Insert the suture into the slot and attach it.The other part of the suture is stretched by hooking the folded part to the hooking piece of the mounting part, and the wrapping part covers the mounting part with the suture tensioned. Storage of medical sutures, comprising a package that encloses the main body of the mount in a sterilized state after storing the package, and when in use, the head part is separated from the main body of the mount together with the packaging by tearing means, and the tip of the suture thread is exposed. It provides a container. The covering part that covers the suture thread mounting surface of the mounting part together with the suture thread may be composed of one piece or two pieces.Furthermore, the latching piece that latches the folded part of the suture thread is:
It is preferable to make an incision at a part of the placement part corresponding to each folded part of the suture to be placed and fold back one incision piece, but the invention is not limited thereto, for example, a hooking piece having a curved guide surface can be formed. The folded portion of the 0 mount main body, which can be attached to the folded portion of the mounting portion, and the folded portion of the folded portion of the hooking piece of the suture thread placement portion may be formed by a single press crease line as required, or T can be formed with double press fold lines to provide the required suture storage space. Also,
It is preferable that the package for packaging the mount on which the suture thread is placed in a sterile state is made of a heat-sealable material, and that the package is also provided with tearing means corresponding to the tearing means for removing the head.

厘Specific Structure of the Invention A medical suture storage container according to the present invention will be described in detail with reference to a preferred embodiment shown in the accompanying drawings.The medical suture storage container l of the present invention is as shown in FIG. , a tearable and removable head part A1, a suture mounting part B provided integrally with the head part A, and a suture thread mounting part B provided integrally with this mounting 'f16B via a folding part and enclosing the mounting part. The mount comprising the mount consisting of the enveloping portion C for the purpose of the encapsulation is not limited to paper, but may be any sheet material that can be torn, is resistant to sterilization, and whose incised pieces can support the suture thread when the thread is pulled out. It can be anything.

The head mA of the mount has a groove 4 for inserting the distal end 3 of the suture thread 2 and a hole 5 of a desired shape such as a circular or oval shape for accommodating the distal end 3 of the inserted suture thread. A tearing means is provided between the head part A and the mounting part B, so that the head part A can be torn and removed when used. The tearing means can be composed of, for example, a V-shaped cut 6 and a cut groove 7, as shown in FIG.

The mounting part B is a substantially rectangular part on which the part 8 of the suture thread 2 other than the distal end 3 is placed.The suture thread 2 is folded back at least once and stored on the O mounting part B. The fold @ 9 is placed, the part B is incised at a site corresponding to the fold, and at least one incision and fold is folded back to the side where the suture 2 is present (in the example of FIG. 1, each fold of the suture is It is supported by latching pieces 1G consisting of two pieces per section 9).

The supporting force of the suture by this hook piece must be such that it can support the suture even when the suture is pulled out. As shown in an enlarged view in FIG. 2, the thickness of the paper, the width W and length Ll of the hanging piece 10, or the hanging pieces when two or more hanging pieces are provided, are determined in order to obtain an appropriate supporting force. The latching piece lO, which requires appropriate selection of the opening angle fife, etc., is not limited to this, but for example, a latching member pre-formed to have a bay I & 1lWjJ that smoothly guides the suture thread is sewn onto the mounting part. It can also be provided by being attached to the yarn folding part. □ The envelope @C consists of at least one piece of paper (consisting of two pieces 11° 12 in Fig. 1) having a substantially rectangular shape similar to the placing part B, and is wrapped around the placing part B one after another. wrapped around. In the example shown in FIG. 1, the piece 11 covers the suture thread side of the loading portion l, and the piece 12 covers the loading weight 11B from the back side, and at the same time, presses the above-mentioned latching piece lO to make an appropriate position. The fold s13 existing on the mount also acts to provide supporting force, that is, the mounting portion l
and the covering part C, between the covering parts C, or the hanging piece 1
The fold between G and mounting part B can be made by folding the fold line by single press as shown in Fig. 3, or if a larger suture storage space is required, as shown in Fig. 4. Then, the distal end 3 of the suture 2 is placed on the mounting board configured as described above by the double press and the fold lines separated by the required distance d. It is inserted into the hole 5 through the groove 4f from the front side of the side, and the end s14 is arranged on the back side of the head section as shown by the dotted line. The portion 8 is supported by the hooking piece 10 at the folding portion 9 and is folded back at least once. In the example shown in the first WjA, the portion 8 is folded back twice.

After supporting and disposing the suture thread 2 at the II portion in this way,
The placing portion A is sequentially covered with the covering pieces 11 and 12, and then sealed in a required packaging in a sterile state (
(Refer to No. 5 WjA) It is preferable that the package 15 is also provided with a V-shaped cut 16 as a tearing means at a position corresponding to the position of the V-shaped cut 6 in the head section. It is preferable to seal the periphery with a heat seal part 17 (shown with diagonal lines in FIG. 5).
It is best to use a transparent pufst ivy film bag for packaging.
N, TJF, polyethylene, polypropylene, vinyl chloride or polyethylene, etc., can be constructed of a two-layer woven film with a thickness of about 50P111, and the 60 head parts protrude from the placing part B and the covering part C, and the transparent packaging Since a part of the distal end 3 of the suture thread 2 can be visually observed through the process, there is no possibility of making mistakes in suture selection. I will briefly explain how to use it. Medical suture storage container l of the present invention assembled as described above (No. 51 M)
When using the suture, check the type of suture by looking at the tip 3 of the suture thread 2 on the protruding head part A, and then place one hand on the mounting part B and the other hand on the head part. and packaging 1
Place the head part from the V-shaped cut 16 of No. 5 and the tear cut 6 of the mount as shown in FIG. The distal end 3 of the suture thread 2 is exposed as shown in FIG. 7 by pulling it out through the hole 5 of the ilA. This results in 1
The thread tip s3 exposed from the packaging part can be picked up and pulled out smoothly, one suture thread fi- at a time, without other threads coming out together or intertwining with each other (see Figure 7). ). Furthermore, since the thread tip 3 can be picked out from the beginning, connection to a suture needle can be easily performed. Note that it is also possible to take out all the sutures in the package at the same time.

〔Example〕

The pull-out resistance of the medical suture of the present invention from the storage container for each U8P8 weight of braided silk (non-silicon) and nylon thread is added to 11, and the results are shown in Table 1.The pull-out resistance values in the table are as follows: When 10 threads with a length of 45 mm are stored in a storage container and pulled out one by one, the maximum pull-out resistance is shown in parentheses, and each yarn type and size is measured three times per 10 threads in the storage container. Measure, 3
The average value for 0 times is also shown. The pull-out resistance was measured using Toyo Seiki's Stretch U Gutsufu M at a pull-out speed of 501/-.In each measurement, the same mount (thickness 0.
25 m of high-quality paper) and the same film thickness were used, and the combinations of the dimensional structure of the mounting part B of the mount and the structure of the folded part in *X are as shown in Tables 2 and 3.

In Table 1 showing the suture pull-out resistance of the medical suture from the storage container according to the present invention, as is clear from the comparison of shape indications a and b, the pull-out resistance of the thread is higher than that of the folded paper piece (latching piece 10). On average, the average width of the nigga opening shown in @8b8b is lower than that of the one-sided opening shown in Figure 8a. In addition, as can be seen from the comparison of the shapes shown in the table, sip and C-b, and b-i and C-b, the thread pull-out resistance is
When the shape of the folded part is configured with double press crease lines as shown in Figure 9b to increase the holding space for the suture system, compared to the case where it is configured with a single press crease line as shown in Figure 9a. It was about 66X' lower on average. In addition, in FIGS. 8 and 9, the unit of each dimension is ■.

The pull-out resistance of the suture thread is preferably 100 f or less, based on the feeling of actually pulling it out by hand. Even for thick threads of braided silk that have high suture friction, if the folded part has a double press-fold structure, the resistance value can be made sufficiently lower than the upper limit of the pull-out resistance (100 t) that is considered to be good. .

Table 1 Resistance to thread withdrawal from the container of the present invention Table 2 Table 3 M Specific effects of the invention The medical suture storage container of the present invention has many effects as described below〇ω All types of medical sutures It can be applied to many objects and can be stored without falling at an acute angle.

■ When in use, the tip of the suture can be exposed so that the suture can be taken out one by one by simply tearing off the head.■ In this way, the tip of the suture Since the exposed part and the other part of the thread are tensioned in an orderly manner on the placing part, there is no problem such as fraying or tangling when the thread is pulled out.

(2) The folding structure of the mount and folding hook piece has been devised, resulting in low thread pull-out resistance and easy handling. The suture thread can be easily connected to the suture needle, improving work efficiency in suturing surgery.The suture thread on the head part that comes out from the center of the mounting part through the transparent packaging can be visually observed. , excessive WA does not occur when selecting threads, etc.
