The invention relates to a flexible-arm
robot for a single-pore laparoscopic minimally-invasive operation, which relates to the minimally-invasive operation
robot. The
robot aims at solving the problems in the traditional
endoscope minimally-invasive operation that multiple
skin incisions of a patient exist and the size of the operation robot is larger. A drive box is connected with a base through a first lead rail and is driven by a first motor which is fixed on the base so as to enable an entire flexible arm to deeply stretch into an
abdominal cavity of the patient; a second motor drives a first finger to open and close through a first drive wire; a third motor drives a
second finger to open and close through a second drive wire; a fourth motor drives a third arm of a flexible joint arm to make a pitching motion through a third drive wire; a fifth motor drives a fourth arm of the flexible joint arm to make an oscillating motion through a fourth drive wire; a sixth motor drives a
drive shaft rotating joint to make a pivoting motion through a fifth drive wire; a seventh motor drives a
wrist joint to make a pitching motion through a sixth drive wire; and an eighth motor drives a first connecting rod and a second connecting rod in the horizontal direction through a lead screw and a second lead rail, so that a first flexible support and a second flexible support are driven to move. The flexible-arm robot is used for the single-pore laparoscopic minimally-invasive operation.
