Abstract
Official abstract text for this publication.
Provided is a manipulator including a first forceps piece and a second forceps piece, which are connected by a pivotal axle and have a gripping part opened or closed on a leading end side thereof. The manipulator includes a manipulation member that is connected to a base end side of the pair of forceps pieces, and moves forward or backward in an axial direction to open or close the gripping part, a first buffer part that has a first spring constant, and undergoes elastic deformation to change a grasping force generated at the gripping part on the basis of the first spring constant and a pulling amount of the manipulation member, and a stopper that regulates the elastic deformation of the first buffer part.
First claim
Opening claim text (preview).
The invention claimed is: 1. A manipulator comprising: a first forceps piece comprising a first gripping surface, and a second forceps piece comprising a second gripping surface, wherein the first forceps piece and the second forceps piece together form a pair of forceps pieces, and wherein the first forceps piece and the second forceps piece are coupled to an axle so as to be pivotable in relation to each other to exert a grasping force through the first gripping surface and t…
