Prosthetic or robot part

摘要

A prosthetic or robot part, comprising a base, a proximal and a distal. The proximal is mounted on the base so as to be rotatable thereabout in a given sense. The distal is mounted on the proximal so as to be rotatable thereabout in the same sense to effect a gripping action of the prosthetic or robot part. The proximal and the distal are rotatable in the opposite sense to release the grip. One part of a drive of the part is pivoted to the base about a base pivot axis. Another part of the drive is pivoted to the distal about a distal pivot axis. The distal is also pivoted to the proximal about the said distal pivot axis. Thus the proximal, the distal and the said another part of the drive are all pivotable relative to one another about the said distal pivot axis.

1. A prosthetic or robot part, comprising a base, a proximal segment and a distal segment, in which the proximal segment is mounted on the base so as to be rotatable thereabout in a first direction, and the distal segment is mounted on the proximal segment so as to be rotatable thereabout in the first direction to effect a gripping action of the prosthetic or robot part, the proximal segment and the distal segment being rotatable in a second direction which is opposite to the first direction to release the grip, wherein a first part of a drive of the prosthetic or robotic part is pivoted to the base about a base pivot axis and a second part of the drive is pivoted to the distal segment about a distal pivot axis, the distal segment also being pivoted to the proximal segment about the said distal pivot axis, so that the proximal segment, the distal segment and the said second part of the drive are all pivotable relative to one another about the said distal pivot axis, and wherein said drive is a helical drive.
