摘要： A tissue fastening apparatus includes a tissue fastening tool, with fastens a first biological tissue and a second biological tissue so as to bring the tissues into close contact and an applicator for indwelling the tissue fastening tool. The tissue fastening tool is made of an elastic wire rod and is wound in a coil shape. The applicator includes a needle tube accommodated in an inner cavity with the tissue fastening tool stretched, a stylet inserted into the inner cavity of the needle tube nearer to the proximal side than the tissue fastening tool, and a rotating mechanism that rotates the stylet around an axis when the stylet is moved toward a distal end of the needle tube. The tissue fastening tool and the stylet are disengageably engaged with each other and integrally and rotatably connected with each other. The rotating mechanism rotates the stylet in a direction opposite to the winding direction of the tissue fastening tool as seen from the proximal side.

摘要： An endoscope system comprises an endoscope, medical instrument, operating unit, first and second drive units, and control unit. The endoscope comprises a flexible insertion tube being inserted into an object being examined. The medical instrument is partially inserted into the object through the insertion tube and the operating unit is used for commanding the medical instrument to operate. The first drive unit drives the medical instrument to enable an inserting and pulling-out operation of the medical instrument with the object through the insertion tube. The second drive unit drives the medical instrument to enable the medical instrument to perform a therapeutic operation in the object. The control unit controls drive of the first and second driving devices depending on both an operated state of the operating device and an interference state caused between the medical instrument and the insertion tube when the instrument is actually used.
