View Patent ↗A medical manipulator and a cleaning method therefor are provided. The medical manipulator includes an operation command unit equipped with a motor, and a working unit, which is detachable with respect to the operation command unit. A connector of the working unit is connected to the operation command unit, and includes pulleys that engage with the motor, the connector serving to rotatably retain the pulleys therein. The connector has an elongate shape extending in the longitudinal direction of a connecting shaft, and a first cleaning hole is arranged in an end portion of the connector that is opposite to a side on which the connecting shaft is connected. A second cleaning hole opens into an interior cavity, in the vicinity of an end portion on the side where the connecting shaft is connected. The end portions are shaped substantially hemispherically.
1. A cleaning method for a medical manipulator, said medical manipulator comprising:
a drive unit equipped with a rotary actuator; and
a working unit which is detachable with respect to said drive unit, said working unit comprising a distal end working unit which is operatively connectable to said rotary actuator,
wherein said working unit further comprises:
a driven rotating body engaged with said rotary actuator at a connection location of said drive unit;
a retaining chamber for rotatably supporting and retaining said driven rotating body; and
at least one cleaning hole through which a cleaning agent is made to flow into and through said retaining chamber,
the cleaning method comprising the steps of:
detaching said working unit from said drive unit;
connecting and sealing said cleaning hole to one end of a tube;
providing a cleaning agent suction and discharge means on another end of said tube;
immersing an end of a shaft of said medical manipulator into said cleaning agent; and
operating said suction and discharge means to repeatedly carry out sucking and discharging of said cleaning agent from the end of said shaft, and thereby causing said cleaning agent to contact and flow through said retaining chamber.
2. The cleaning method for a medical manipulator according to claim 1 , wherein said cleaning hole comprises two cleaning holes, one of said cleaning holes being connected to said tube, and the other of said cleaning holes being blocked.
3. The cleaning method for a medical manipulator according to claim 1 , wherein said cleaning hole comprises two cleaning holes, and said tube comprises two tubes, which are connected respectively to said two cleaning holes.
