Definitions
- the present invention relates to a surgical pad for absorbing bodily fluids such as blood, lymph, and spinal fluid generated from a surgical site in a surgical operation, and more particularly, in a brain surgery, an intraventricular ventricular system and a subarachnoid system.
- the present invention relates to a surgical pad for effectively absorbing cerebrospinal fluid that oozes from a cavity without damaging brain cells.
- absorbent articles such as cut cotton, gauze, and surgical pads are used as necessary to absorb and remove body fluids such as blood, lymph and spinal fluid.
- absorbent articles of relatively small size are used to absorb body fluids such as lymph, blood and spinal fluid.
- body fluids such as lymph, blood and spinal fluid.
- a small-sized absorbent article absorbs bodily fluids, it becomes difficult to distinguish it from the tissue at the surgical site, and it may be left in the body by mistake after the operation.
- Patent Document 1 in order to ensure the removal of the surgical pad, a contrast thread (X-ray impermeable resin yarn) is attached to the pad portion, and X is closed before closing the surgical site at the end of the surgery. It is known that the presence or absence of a surgical pad is confirmed using a contrast thread as a clue by performing line contrast (X-ray imaging).
- a contrast thread X-ray impermeable resin yarn
- a thread-like filament obtained by twisting a filamentous material composed of a filament of barium sulfate having a contrast function and a polypropylene resin is used as a contrasting thread for X-ray contrast after the operation.
- Such a filamentous filament is easy to absorb liquid due to its structure, and since the contrast yarn is made of resin, it has a property of absorbing moisture and becoming hard. Touching it can damage tissue, especially delicate brain tissue during brain surgery.
- the gauze or absorbent cotton is also used for the pad portion because the fine thread material from the cut end portion is likely to fall off. Therefore, as disclosed in Patent Document 1, a large number of non-woven fabrics are laminated. However, even a pad using a non-woven fabric cannot completely prevent lint or flaking of the yarn feather material from the surface.
- a further object is to provide a surgical pad that can be detected by X-ray contrast after surgery.
- the present invention provides a surgical pad that absorbs body fluids such as lymph, blood, and cerebrospinal fluid during a surgical operation, and is a pad portion formed by laminating a plurality of absorbent fabrics. And a coating portion in which the surface of the pad portion is formed of a resin, and a surface or a surface between the laminated cloths in the pad portion (in the present application, “surface” means any surface on both sides of the pad portion) And a radiopaque substance-containing sheet disposed in (2).
- the X-ray opaque substance-containing body is formed into a sheet and disposed between the layers of the pad cloth or on the surface thereof, so that it does not absorb blood and body fluid and harden.
- the X-ray opaque substance-containing sheet is a film-like sheet having a thickness of micron in which the X-ray opaque substance is kneaded into the base material.
- the impermeable substance-containing sheet is characterized in that the X-ray impermeable substance is coated on the surface of the substrate, and the substrate used for the impermeable substance-containing sheet is made of a resin.
- the X-ray opaque substance-containing sheet is formed by placing a X-ray opaque substance in a sheet-like thermoplastic resin plate disposed between or on the surfaces of the laminated pads, and the thermoplastic resin plate. Is heat-sealed to the pad portion. Thereby, the said cloth and the said X-ray opaque substance containing sheet
- the smoothness is enhanced when the diameter of the resin material particles of the coating is 5 ⁇ m or less.
- the particles are formed of a hydrophilic resin or a material containing a hydrophilic resin, the pad can be further easily taken out.
- the surface of the pad portion is coated with a resin.
- the cloth since the surface of the pad part is covered with the coating of the resin material, lint and fluff peeling of the surface can be prevented. Therefore, the cloth may be a non-woven fabric or a woven cloth, and a cloth excellent in functions such as absorbability can be selected.
- the coating resin material contains an antibacterial agent.
- the drawn yarn is made of natural materials, especially silk, it will be soft when it absorbs blood and body fluids, and it will have little friction with the body tissue.
- the surgical pad according to the present invention since the X-ray impermeable substance-containing body is formed into a sheet, the body fluid such as lymph, blood, and cerebrospinal fluid generated in the surgery is not absorbed and cured. Therefore, the friction with the body tissue is small and the tissue is prevented from being damaged. Furthermore, since the radiopaque material can be captured on the surface of the sheet during X-ray imaging, the surgical pad can be reliably detected.
- Fig. 2 shows a part of the AA cross section of the surgical pad shown in Fig. 1. It is a figure explaining the structural example which a radiopaque substance contains in a radiopaque substance containing sheet

- FIG. 2 shows a part of a cross section taken along line AA of FIG.
- the pad portion 1 is formed by laminating and integrating a plurality of absorbent cloths 2 (for example, 60 mm ⁇ 30 mm), and the surface of the pad portion 1 is coated with a resin material 4.
- the coating 4 allows fine resin particles to enter the fine gaps on the surface of the cloth 2, thereby preventing yarn lint from dropping and fluff peeling on the surface, and effectively preventing yarn from falling off the cut surface.
- the coating process includes a coating process by thermal fusion, and the removal of lint and fluffing of the surface of the cut part are eliminated by the coating process, so that it is possible to eliminate the risk of suppuration at the cut part after the operation.
- the cloth 2 is not limited to a non-woven fabric, and a highly absorbent material can be used.
- the diameter of the particle of the coating treatment with the resin material is 5 ⁇ m or less at this time, there is an advantage that it enters into the surface of the pad part 1 more and forms a strong film, which makes it difficult to adhere to the body tissue.
- the resin material used for this coating treatment examples include silicon resin (silicon compound), PET (polyethylene terephthalate), PP (polypropylene), and the like. Silicone resin is preferred. This makes it easier to pull out the surgical pad from the body. Therefore, the resin material in the surgical pad is preferably a hydrophilic resin or a material containing a hydrophilic resin.
- an antibacterial agent in the resin material used for the coating treatment.
- various organic and inorganic substances can be used as the antibacterial agent added to the resin material.
- organic antibacterial agents have immediate effects, they have shortcomings in antibacterial properties and are inferior in heat resistance.
- the components of inorganic antibacterial agents are metals, and silver, copper, zinc and zeolite are actually used.
- silver since silver has a large antibacterial effect, silver is the main antibacterial component in inorganic antibacterial agents.
- Silver-based antibacterial agents are preferred, antibacterial effect life is semi-permanent, and heat resistance is excellent.
- the surgical pad since the surgical pad is disposable, the lifetime of the antibacterial property does not matter so much, but regarding the heat resistance, it is necessary to consider the processing temperature at the time of resin molding. Therefore, if the resin material covering the surface of the pad portion 1 has antibacterial properties, the type of the antibacterial agent is determined based on these points.
