| 20120076613 | MALE FASTENING TOOL - A male fastening tool body includes a body part, a flange part which has a seat surface, an annular concave part formed between the body part and the seat surface, and a resinous ring-shaped member disposed at the annular concave part. The annular concave part has an annular concave peripheral edge portion. The resinous ring-shaped member has an annular projected part which fills almost the entire annular concave part and a lower surface of which is projected downward beyond the seat surface and an annular peripheral part, having a tapered bottom surface or a curved bottom surface, which is formed between the annular projected part and the outer edge of the resinous ring-shaped member and becomes gradually thinner, with an outer edge of the resinous ring-shaped member being located at an outer edge of the annular concave peripheral edge portion or slightly toward the side of the body part. | 03-29-2012 |
| 20100298936 | TENSILE FORCE-ADJUSTABLE FIXING TOOL FOR FIXING TENDON GRAFT AND LIGAMENT RECONSTRUCTION METHOD - A fixing tool used in a ligament reconstruction operation to fix a tendon graft having a bone plug can be inserted into a bone tunnel formed at a bone. The fixing tool includes a fixing member having a main body part provided with a through-hole and two spike parts which extend almost parallelly and can be stricken into the bone and a fixing screw including a shaft part having a self-tap portion and a male screw portion, a head part, and a lumen. The fixing screw can be screwed into the bone plug in a state where a guide pin pierced into the bone plug is penetrated through the lumen of the fixing screw and a pulling member mounted to the bone plug and extended from the bone tunnel is being pulled. The fixing screw can be adjusted a tensile force of the tendon graft by adjusting an amount of screwing of the fixing screw into the bone plug after the head part of the fixing screw contacts to the fixing member. | 11-25-2010 |

| 20100003106 | BOLT - A bolt has a bolt body including a screw part, a head part formed at an upper end of the screw part, and a flange part formed at a lower end of the head part; and an unconductive ring-shaped resinous member covering a peripheral portion of the flange part. The flange part has a disk-shaped flange body portion; and a seat surface-forming portion having a seat surface which is pressed against a portion where the bolt is to be mounted. The ring-shaped member has an edge part which is located at a position nearer to a lower end of the screw part than the seat surface and outward from the flange body portion and an annular skirt part whose diameter gradually increases to the edge part. The annular skirt part is so formed that it deforms when the bolt is mounted on the portion where the bolt is to be mounted and forms an annular liquid-tight sealing portion for the portion where the bolt is to be mounted. | 01-07-2010 |
