Description

  The present invention relates to a gauze ball used for exfoliating a tissue or absorbing blood and body fluids, for example, during a surgical operation, and a method for manufacturing the same.

  2. Description of the Related Art Conventionally, in surgical operations, surgical gauze is rolled up or gauze balls formed in advance in a spherical shape are used for the purpose of absorption of blood and body fluids, and separation of body tissues.

  Such gauze balls are often formed by folding and rounding a gauze body in which an X-ray contrast yarn is woven in order to prevent it from being left behind in the body. The gauze ball formed in this way is hard on the surface of the gauze ball because the X-ray contrast yarn itself woven into the gauze body is thicker, less flexible and harder than the gauze yarn generally used. A convex part is formed, and this convex part may come into contact with the body tissue and damage the body tissue.

In order to solve such a problem, a gauze ball that does not expose the X-ray contrast yarn on the surface of the gauze ball and a manufacturing method thereof are known. In this manufacturing method, a substantially square gauze body having an X-ray contrast yarn arranged along the weft direction or the warp direction is folded into a triangular shape with the diagonal line as a fold, and is folded so as to round the vicinity of the diagonal line. Form a fold, close both sides of the fold and bring them together so that the X-ray contrast thread is inside and roll it into a cylindrical shape, and then wrap the other part of the gauze body around the fold. Thus, the gauze ball | bowl whose folding part becomes a folding belt | belt-shaped convex part is completed by folding in a ball shape (for example, refer patent document 1).

  In the gauze ball described in Patent Document 1 described above, since the X-ray contrast thread is not exposed to the outside, the problem that the X-ray contrast thread directly contacts the body tissue is solved.

  On the other hand, the portion where the X-ray contrast yarn is located is likely to come into contact with the tissue in the body because some steps or hard portions remain even if the X-ray contrast yarn is covered with the gauze yarn. It is basically undesirable that the X-ray contrast yarn is located in the portion.

  However, in the gauze ball described in the above-mentioned Patent Document 1, the X-ray contrast yarn is positioned in the vertical direction (vertical direction), so that the vicinity of the folded belt-like convex portion is pinched with tweezers or the like, and the surface of the gauze ball main body is picked up. When contacting with a body tissue or the like, a portion that can contact the body tissue while avoiding a step and a hard portion due to the X-ray contrast yarn is divided by the X-ray contrast yarn on both sides and is not necessarily wide. The inclination of the X-ray contrast yarn in the gauze ball described in Patent Document 1 varies depending on the position of the X-ray contrast yarn woven into the gauze body from the end of the gauze body, but is basically positioned in the vertical direction. There is no change.

  This is related to the direction in which the gauze body is first folded in the gauze ball described in Patent Document 1. That is, since it is folded first along the diagonal line of the gauze body, the X-ray contrast yarn arranged along the weft direction or the warp direction is inclined with respect to this diagonal line, and a folded belt-like convex part is formed on this diagonal This is because the folded portion is formed so that the direction of the X-ray contrast yarn with respect to the diagonal becomes the inclination of the X-ray contrast yarn positioned on the completed gauze ball.

  The configuration of the gauze ball according to the first embodiment of the present invention will be described below with reference to FIGS.

  1 to 3, reference numeral 1 denotes a gauze ball. The gauze ball 1 includes a ball-shaped gauze ball main body 2 and a folding belt-shaped convex portion 3 disposed along the upper portion of the gauze ball main body 2. I have. In this gauze ball 1, wefts and warps alternately intersect with each other, and either one of the wefts or warps (in this embodiment, warps) alternately intersect with the X-ray contrast yarn 5 in a plain weave. It is formed by folding a substantially square gauze body 6.

  The gauze ball main body 2 is a part used for, for example, surgery such as a surgical operation or medical use to contact a subject to absorb blood or body fluid, and the gauze ball main body 6 is folded in a small size. It is rolled and molded.

  The folding belt-like convex portion 3 is a portion that is pinched by a user with tweezers or the like to fold the gauze body 6 in order to avoid contact with the body tissue and use only the gauze ball body 2 as a contact surface with the body tissue. In the state in which the gauze ball main body 2 is divided into two substantially upper and lower parts 11 and 12 by a virtual bisector DL1 as a virtual multi-divided line, the side parts 13 and 14 and the central part 15 Are positioned in the upper portion 11 and not in the lower portion 12.

  Each of the wefts and warps of the gauze body 6 is formed into a thread-like material that is spun linearly with a material such as cotton, cellulose fibers such as rayon, or a mixture of cellulose fibers and plastic fibers such as polypropylene or polyester. ing.

  The X-ray contrast thread 5 is, for example, a filament formed in a single continuous thread with an X-ray contrast medium and a plastic resin, and has a certain thickness so that it can be easily confirmed during X-ray imaging. It is arranged along the longitudinal direction of the gauze main body 6 and intersects with the wefts alternately above and below.

  Here, as an X-ray contrast agent, barium sulfate or the like is used as a material. As the plastic resin, polyvinyl chloride, polypropylene, polyester, polyethylene, polystyrene, silicone, or the like is used.

  For this reason, the X-ray contrast yarn 5 is thicker than the wefts and warps of the gauze body 6, is formed to be hard without flexibility, and has a different color from these wefts and warps. The gauze body 6 is disposed substantially parallel to the one side of the gauze body 6 at a predetermined distance L1.

  Further, the X-ray contrast yarn 5 is, for example, one end side is located in the vicinity of the side portion 13 of the folded belt-like convex portion 3 and the other end side is formed between the central portion 15 and the side portion 14 when viewed from the outside of the gauze ball main body 2. It arrange | positions so that it may be located in a substantially intermediate part. That is, the X-ray contrast yarn 5 is located in the upper portion 11 and has a longitudinal shape in the left-right direction shown in FIG.

  Accordingly, in the present embodiment, the gauze ball main body 2 is a portion in which the right half and the lower left half shown in FIG. 2 can safely contact the body tissue of the subject.

  Next, the operation of the first embodiment will be described.

  When the gauze ball 1 is formed, the gauze body 6 is appropriately folded and rolled to form a ball-shaped gauze ball body 2 and a folded belt-like convex portion 3 along the upper side of the gauze ball body 2.

  In use, the folding belt-like convex portion 3 is sandwiched by tweezers, the gauze ball body 2 side is brought into contact with the body tissue of the subject, and the tissue is peeled off or blood or body fluid is absorbed. To do.

  At this time, the X-ray contrast thread 5 is disposed near the folding belt-shaped convex portion 3 and the X-ray contrast thread 5 does not exist below the virtual bisector DL1, so that the X-ray contrast thread 5 exists. It is possible to secure a wide area of the portion that is not, in other words, the portion that can safely contact the body tissue.

  That is, the X-ray contrast yarn 5 is thicker, less flexible, and harder than the weft and the warp. Therefore, when the X-ray contrast yarn 5 contacts the body tissue of the subject, the body tissue may be damaged. Therefore, the X-ray contrast thread 5 of the gauze ball 1 is previously disposed at a position where there is little possibility of contact with the tissue in the body, that is, in the upper portion 11 in the vicinity of the folding belt-shaped convex portion 3, thereby damaging the body tissue. The gauze ball 1 makes it possible to exfoliate the tissue and absorb blood and bodily fluids while suppressing worries.

  As a result, it is not necessary for the user to pay extra attention to the position of the X-ray contrast thread 5 during use, and the gauze ball 1 can be safely contacted with the body tissue as the area of the gauze ball main body 2 increases. Since the amount of absorption of blood or body fluid per one increases, the number of gauze balls 1 to be used or the number of times of replacing the gauze balls 1 during the operation can be reduced, and the workability of the operation is improved.

  In addition, by setting the virtual multi-segment line as the virtual bisector DL1, the length of the X-ray contrast thread 5 that can be seen from the outside of the gauze ball 1 can be secured, and the gauze ball 1 is left in the body of the subject. Can be prevented more reliably.

  Furthermore, by exposing the X-ray contrast thread 5 to the outside of the gauze ball body 2, the user can easily visually recognize the X-ray contrast thread 5.
