Document Type and Number:
WIPO Patent Application WO/2019/097560
Kind Code:
A1
Abstract:
To address the problem of preventing an endoscope or an overtube from becoming large in diameter and eliminating the need to interchange a tissue grasper and a needle grasper, this medical grasper (1) includes: a long insertion part (2); a grasping part (3) that is disposed on the distal end of the insertion part (2); a manipulable part (4) that is provided on the proximal end of the insertion part (2); and a power transmission part (5) that transmits to the grasping part (3) the drive power input into the manipulable part (4). The grasping part (3) includes a pair of grasping pieces (6, 7) that are supported so as to be pivotable relative to each other, and each of the grasping pieces (6, 7) has a needle grasping part (9) that grasps a needle (19) and a tissue grasping part (8) that grasps tissue and is disposed in a position farther away from a pivot shaft (A) than the needle grasping part (9).
