Abstract
A working mechanism for a medical manipulator and a cleaning method therefor are provided. A working unit of a medical manipulator is equipped with a hollow connecting shaft, wires of a motive force transmitting member disposed in the connecting shaft, and a distal end working unit disposed on one end of the connecting shaft and which is moved by the wires. A cover covers at least a portion of the distal end working unit. A gap is provided between the cover and the connecting shaft, with oblong holes being disposed laterally on right and left sides of the cover. A cleaning agent is made to flow through the holes and the gap and/or a brush may be inserted through the holes and the gap for cleaning the distal end working unit.
Claims4
A working mechanism for a medical manipulator, comprising:
- a hollow shaft;
- a motive force transmitting member disposed in the shaft;
- a working unit disposed at one end of the shaft and equipped with a distal end working unit, which is moved by the motive force transmitting member;
- and
- a cover that covers at least a portion of the distal end working unit and is movable with respect to the shaft together with the distal end working unit,
- wherein a gap is provided between the cover and the shaft, the gap partially exposing the motive force transmitting member and communicating with a hollow space of the shaft,
- holes are disposed laterally on both sides of the cover, the holes partially exposing a driving part of the distal end working unit which is disposed in the interior of the cover, and
- the holes, the gap, and the hollow space defining a flow path, wherein the distal end working unit can be cleaned by flow of a cleaning solution through the flow path.
