Abstract:
1. A thread-fixing tool configured to fix a suture thread passing through a biological tissue, comprising: a first member which has (i) a lumen disposed along a longitudinal axis of the first member and (ii) a communication path disposed along the longitudinal axis of the first member, the lumen being configured to receive the suture thread and the communication path communicating with an intermediate portion of the lumen; and a second member which has (i) a shaft portion configured to be inserted into the communication path of the first member and (ii) a pressing portion formed at a distal portion of the shaft portion and which is capable of deforming outwardly in a radial direction of the shaft portion, wherein a longitudinal axis of the lumen and a longitudinal axis of the communication path extend parallel with each other, the longitudinal axis of the communication path and the longitudinal axis of the lumen are radially offset from each other in a radial direction of the lumen, and the pressing portion is configured (i) to be guided to the communication path and to the intermediate portion of the lumen through the communication path and (ii) to be deformed in a direction crossing an insertion direction of the suture thread to push the suture thread against an inner wall of the lumen.
