Definitions
- the present invention is, for example, a thread used in brain surgery and orthopedic surgery, a small pad for surgery using the thread and a blood vessel tape, which can be found in the body by X-ray imaging etc.
- the present invention relates to a yarn, a small surgical pad, and a blood vessel tape that can contribute to the prevention of residue.
- gauze In the case of surgery, a large number of gauze is used for the purpose of suppression of bleeding, absorption of body fluid and saline, protection of organs from abrasion, dryness and contamination. If these gauze remains in the body, it may not only cause various physical disorders such as pain, discomfort or slight fever, but it may adversely affect not only the organ concerned but also the adjacent organs. It causes unpredictable long-term damage to the digestive system, circulatory system, respiratory system, brain and nervous system, skeletal system etc. and sometimes causes infection. It can also be a source of immune deficiency. Because of this possibility, it is essential to take all the gauze out of the body at the end of the surgery.
- gauze may be used in which one of the warp forming the gauze is replaced with contrast yarn and woven, and radiography (radiography) is performed before closing the surgical site at the end of the surgery.
- radiography radiography
- a method is used in which the presence or absence of residual gauze is confirmed by using the contrast thread as a clue, and all found are removed.
- contrast yarn polypropylene, a multifilament obtained by kneading barium sulfate in a polystyrene resin, or a filament obtained by kneading barium sulfate in polyvinyl chloride or a silicon resin is used (see, for example, Patent Document 1) . Since these resin-based materials have poor water absorbability and do not stain in blood, there is an advantage that even if the gauze main body is stained with blood, for example, if it is a contrasting thread dyed in blue, it is easy to visually recognize even with the naked eye. Those which can not be detected by the naked eye can be detected by radiography.
- Patent Document 2 describes a gauze containing an X-ray contrast yarn for preventing the fibers of the gauze from being detached and the X-ray contrast yarn being detached.
- the X-ray contrast yarn is prevented from falling off by welding and fixing the X-ray contrast yarn containing the thermoplastic fiber to the woven or non-woven fabric.

- Patent Document 3 discloses an absorbent woven fabric attached with a locator string. This yarn is configured by spirally winding a yarn around a bundle of five monofilaments (X-ray contrast yarn) (FIG. 3 of Patent Document 3). In addition, it is described that it is preferable to bind the said monofilament by heat etc.
- the X-ray contrast yarn containing gauze of Patent Document 2 since the X-ray contrast yarn is welded from one end to the other end of the gauze, the ratio of the welded portion to the entire gauze becomes large. Since the welded portion has rigidity, the gauze of Patent Document 2 is very likely to damage the organ. Moreover, in the method of sandwiching the X-ray contrast thread by the water pressure of water jet, for the purpose of preventing the falling out of the X-ray contrast thread, the sandwich of the X-ray contrast thread is strengthened using considerable water pressure. Since the thickness is significantly reduced, the inherent water absorbability and flexibility of the nonwoven fabric are reduced.
- the positioning yarn of Patent Document 3 is considered to lack flexibility because it has a configuration in which a plurality (five in the example) of monofilaments are bound by heat or the like.
- a blood vessel tape used for identifying a blood vessel or the like during operation, pulling a blood vessel, temporarily holding a tissue, and the like.

- Test equipment Automated pure bending tester (KESFB2-AUTO-A) Clamp width: 1 cm Number of measurements: 5 samples Condition: Wet condition (immersed in purified water and wet for 30 minutes)
- Test equipment Constant speed extension type tensile tester Tensile speed: 100 mm / min Holding distance: 15 cm Number of measurements: 5 samples Condition: Wet condition (immersed in purified water and wet for 30 minutes)
- the tensile test was performed using the following pads in each Example and Comparative Example.
- the imaging apparatus used for X-ray CT imaging in Examples 2 and 4 and Comparative Examples 2 and 4 is TOSCANER-32300 ⁇ FPD (manufactured by Toshiba IT Control System Co., Ltd.), and has a tube voltage of 160 kV and a tube current of 80 ⁇ A. The output was 12.8W.
- Example 2 Six non-woven fabrics (Cupla Rayon) were sewn by using a PET yarn as a sewing yarn, and X-ray CT imaging was performed on a pad in which a draw-out yarn made of a braid was welded on the PET yarn.
- 7 (a) is an X-ray CT image of 3D data taken from the welding surface side (the front side of the paper surface of FIG. 1)
- FIG. 7 (b) is a 3D taken from the nonwoven fabric side (the back side of the paper surface of FIG. 1). It is an X-ray CT image concerning data.
- fine spots like those indicate penetration into the non-woven fabric.
- FIGS. 8 to 10 The same applies to X-ray CT images shown in FIGS. 8 to 10 below.
- the tension test was done using the said pad.
- Example 3 Six non-woven fabrics were sewn by cotton yarn, and a tensile test was performed using a pad in which a draw-out yarn made of braid was welded on the cotton yarn.
- Example 4 An X-ray CT imaging was performed on a pad in which a pull-out yarn made of a braid was welded to the uppermost non-woven fabric without sewing six non-woven fabrics. X-ray CT images are shown in FIGS. 8 (a) and 8 (b). Moreover, the tension test was done using the said pad.
- Example 2 using the draw-out yarn which consists of braids, as shown in FIG.7 (b), the amount of penetration is small also at parts other than PET sewing thread. It is considered that this is because all of the PP filaments dissolve in the non-woven fabric, and part or all of the coated yarn of PET having a melting point higher than that of PP remains undissolved. In addition to this, it is considered that the tensile strength of the drawn yarn of Example 2 is higher than that of Comparative Example 2 as described later by the drawn yarn being joined to the PET sewing yarn.
- Example 4 using a drawn yarn made of a braid as shown in FIG. 8 (b), the amount of penetration of the drawn yarn is greater than that of Comparative Example 4 (FIG. 10 (b)) for the same reason as above. It has decreased.
- Example 2 and 3 in order to raise tensile strength, it turned out that it is desirable to weld a leader thread on PET yarn. It is considered that this is because all the filaments made of PP dissolve into the non-woven fabric by welding, and part or all of the coated yarn made of PET having a melting point higher than that of PP remains unmelted. Furthermore, it was confirmed that the variation in tensile strength of Example 2 in which sewing was performed using PET yarn was much smaller than that in Example 3 in which sewing was performed using cotton yarn.
- Example 4 in the pad in which the drawn yarn was welded without sewing the non-woven fabric, the tensile strength was close to the value of both the braid of the present invention and the conventional X-ray contrast yarn.

- FIG. 12 (a) although the sewing thread was partially broken, it was confirmed that the drawn yarn was not broken.
- FIG.12 (b) although the nonwoven fabric fractured partially, it has confirmed that a drawing thread did not fracture
- FIG. 12C since the content of PP in the X-ray contrast yarn is high and the content of PET is low, the amount of PP dissolved in the non-woven fabric is excessive and the remaining PET is decreased. As a result, breakage of the X-ray contrast yarn occurs before breakage of the nonwoven fabric and the nonwoven fabric. From the above, it was confirmed that the pull-out yarn of the present invention does not break in either of the sewing by the PET yarn and the sewing by the cotton yarn.
- the sensor sheet in the configuration in which the first film made of PET provided with silver electrodes arranged in the row direction and the second film made of PET provided with silver electrodes arranged in the row direction are arranged opposite to each other.
