Definitions
- the present invention relates to an absorbent material with an X-ray contrast thread used in endoscopic surgery, which is a nonwoven absorbent material that absorbs blood or other body fluids.
- a gauze for absorbing body fluid, forceps for grasping the gauze, and a trocar for passing the forceps holding the gauze are used to wipe off blood or other body fluid in a body cavity.
- a trocar is a thin tube with a circular cross section, which is inserted into the body cavity from outside the body.
- the gauze with the X-ray contrast thread is inserted into the body cavity with forceps through the trocar of the thin tube, and is taken out of the body from the body cavity.
- the endoscope and trocar are inserted into the patient's abdomen at different positions.
- the trocar penetrates the patient's abdomen on the distal side, with the distal opening in the abdominal cavity and the proximal opening outside the abdomen.
- the forceps holding the gauze with the X-ray contrast thread at the distal end of the trocar are inserted into the trocar through the proximal opening, and the forceps inside the trocar are advanced.
- the gauze with the X-ray contrast thread protrudes from the tip opening of the trocar, enters the abdominal cavity, and is immersed in body fluid such as blood flowing into the abdominal cavity. Fluid in the peritoneal cavity is absorbed by gauze with X-ray contrast thread.
- the gauze with the X-ray contrast thread that has sucked the bodily fluid in the abdominal cavity is grasped by the grasping portion of the forceps protruding from the tip opening of the trocar while looking through the endoscope inserted into the abdominal cavity, and the forceps in the trocar are retracted.
- the gauze with X-ray contrast thread containing body fluid is drawn into the trolley from its tip opening.
- the grasping forceps grasping the gauze with the X-ray contrast thread containing the body fluid is further retracted and pulled out of the toro-force.
- the gauze with X-ray contrast thread containing body fluid is pulled out from the inside of the trocar through its proximal end opening, and taken out of the abdomen.
- the gauze with X-ray contrast yarn for endoscopic surgery is made by weaving X-ray contrast yarn as warp yarn in a cotton yarn woven gauze.
- the gauze is cut into strips sized to pass through the trocar.
- the X-ray contrast yarn is arranged along the long side at the center of the gauze in the short side direction.
- the X-ray contrast yarn is made of a thermoplastic resin yarn, and one or a few of the yarns are thermally fused to the gauze cotton yarn. 0 0 2—2 3 8 9 4 3
- gauze with X-ray contrast thread for endoscopic surgery is to supply and stack nonwoven fabric, X-ray contrast thread, fiber sliver or woven gauze in a desired order on a belt conveyor, Water is blown in the vertical direction to entangle the fibers. ⁇
- the laminate is integrated.
- the laminate is cut into strips sized to pass through the trocar.
- the X-ray contrast yarn is sandwiched between the nonwoven fabric and the nonwoven fabric or the nonwoven fabric and the gauze on both sides of the laminate, and is arranged along the long side direction of the laminate. Disclosure of the invention
- gauze for endoscopic surgery When gauze for endoscopic surgery is immersed in bodily fluid such as blood flowing into a body cavity, it absorbs bodily fluid and becomes the same color as bodily fluid, and absorbs bodily fluid and sinks into bodily fluid. Then, the gauze with the X-ray contrast thread immersed in the body fluid of the body cavity becomes difficult to find with an endoscope inserted into the body cavity. Gauze with X-ray contrast thread, which cannot be seen with an endoscope, is difficult to grasp with forceps. It is difficult to take out of the body cavity. There is a high risk of being left in the body cavity.
- gauze for endoscopic surgery particularly woven gauze, absorbs body fluid when immersed in body fluid such as blood in a body cavity, loses its waist, and becomes complicatedly curved and clumped. Then, it is almost impossible to find out from the gauze that is immersed in bodily fluids, the position or part of the gauze that is desired to be grasped with forceps with an endoscope inserted into the body cavity.
- gauze for endoscopic surgery is taken out of the body cavity, it is squeezed by the trocar when the body fluid in the body cavity is sucked, grasped by the grasping part of the forceps protruding from the tip opening of the trocar, and pulled into the trocar.
- a part of the body fluid that was sucked out Return to the body cavity.
- the amount of bodily fluid that returns to the body cavity varies depending on the position or part of the gauze picked with forceps. The smaller the amount of body fluid squeezed out of the gauze and returning to the body cavity, the better the efficiency of body fluid wiping.
- the woven gauze / nonwoven fabric is an absorbing material, absorbs blood or other body fluids, becomes the same color as the body fluids, and loses its waist.
- X-ray contrast yarns are synthetic resin yarns such as polyvinyl chloride, polypropylene, and polyester containing the contrast agent barium sulfate. It is a thread that does not absorb body fluids such as blood, does not become the same color as body fluids, and does not lose its waist.

- strip-shaped gauze grasps the center position in the long side direction or short side direction with forceps. Then, when the trocar is pulled into the trocar from its tip opening, the resistance is large and strongly squeezed when passing through the trocar tip opening, and the amount of body fluid sucked into the gauze is squeezed out and returned to the body cavity. The amount of body fluid wiping the body cavity is reduced.
- the strip-shaped gauze grasps the corner where the long side and the short side intersect with forceps, When pulled into the locale through its tip opening, the resistance that passes through the tip opening of the trocar is small, it is not strongly squeezed, and the amount of body fluid squeezed out of the gauze and the amount of body fluid returning to the body cavity is reduced. A greater amount of body fluid is wiped off.
- the end of the X-ray contrast yarn protruding from the absorbing material is easy to find even if the absorbing material absorbs the body fluid, so that the end of the X-ray contrast yarn protrudes from the absorbing material. Therefore, the end of the X-ray contrast yarn protrudes from the corner of the strip-shaped absorbing material.
- the protruding end of the X-ray contrast yarn is easy to find, and when following the protruding end, it reaches the corner of the strip-shaped absorbent material. That is, it is easy to find the corners of the absorbent material gripped by the forceps.
