Abstract

A robotic surgical assembly includes a support, one macro-positioning arm, connected to the support and having a plurality of degrees of freedom. The macro-positioning arm includes a support member, at least two micro-positioning devices, each having a plurality of motorized degrees of freedom, connected in cascade to the support member of the macro-positioning arm, and at least two medical instruments. Each instrument is connected in cascade to each of the micro-positioning device and includes a jointed device having a plurality of motorized degrees of freedom including a plurality of rotational joints. Each of the at least two medical instruments has a shaft, suitable for distancing the jointed device from the micro-positioning devices by a predetermined distance in a shaft direction.

Claims13

Dependent claims

A robotic surgical assembly comprising:

at least one micro-manipulator;
a motor box, attached to the micro-manipulator;
and
a medical instrument comprising a shaft extending along an axis of longitudinal development, a transmission box at one end of the shaft, and a jointed device at the other end of the shaft;
wherein
said at least one micro-manipulator comprises a motorized rotary joint for rotating the medical instrument around a longitudinal axis of rotation that coincides with the axis of longitudinal development of the shaft;
and
wherein
said motor box contains a drive system equipped for driving the jointed device, and said transmission box contains a transmission mechanism to transmit motor motion to the jointed device;
said medical instruments comprises tendons extending through the mechanical transmission box and said shaft, and said jointed device comprises a plurality of tendon-actuated rotational joints;
and
wherein
the motor box and the transmission box are connected to each other.
