Embodiment Construction

[0027] as in figure 1 As shown in , the robotic guidance system employs a robotic unit 10 and a control unit 20 for any endoscopic procedure involving endoscopic imaging of a vascular tree with one or more bifurcations (ie, branches). Examples of such endoscopic procedures include, but are not limited to, minimally invasive cardiac surgery (eg, coronary artery bypass grafting or mitral valve replacement).

[0028] The robotic unit 10 comprises a robot 11 , an endoscope 12 rigidly attached to the robot 11 and a video capture device 13 attached to the endoscope 12 .

[0029] Herein, a robot 11 is broadly defined as any robotic device structurally configured with motorized control for manipulating one or more nodes of an end effector as required by a particular endoscopic procedure. In practice, the robot 11 may have four (4) degrees of freedom, such as, for example, a tandem robot with nodes connected in series to rigid segments, nodes mounted in a parallel sequence (e.g., Stew...

Abstract

An image registration system an endoscope (12) and an endoscope controller (22). In operation, the endoscope (12) generates an intra-operative endoscopic image (14) of a vessel tree (e.g., an arterial tree or a venous tree) within an anatomical region, and the endoscope controller (22) image registers the intra-operative endoscopic image (14) of the vessel tree to a pre- operative three-dimensional image (44) of the vessel tree within the anatomical region. The image registration includes an image matching of a graphical representation of each furcation of the vessel tree within the intra-operative endoscopic image (14) of the vessel tree to a graphical representation of each furcation of the vessel tree within the pre-operative three-dimensional image (44) of the vessel tree.

Description

[0001] This application claims the rights of common patent application PCT / IB2011 / 053998, filed September 13, 2011, entitled "Robotic Control of an Endoscope from Blood Vessel Tree Images". technical field [0002] The present invention generally relates to intraoperative registration between preoperative three-dimensional ("3D") vascular tree images and intraoperative endoscopic vascular tree images. The present invention relates in particular to an intraoperative registration merging method for accounting for any changes in the topology of the vascular tree during coronary surgical procedures. Background technique [0003] Coronary artery bypass grafting ("CABG") is a surgical procedure for revascularization of blocked coronary arteries. Approximately 500,000 procedures are performed in the United States each year. In conventional CABG, the patient's sternum is opened and the patient's heart is fully exposed to the surgeon. Although the heart is exposed, some arteries wi...
