Abstract:Abstract. MARGE is a joint project in the framework of the interdisciplinary national program in Robotics, called ROBEA, launched by the French National Research Center (CNRS) in 2001. The focus is on the development of design methodologies and on the control of high mobility and dexterity assistive devices for complex gesture assistance in minimally invasive surgery, especially for coronary artery bypass grafting. This paper presents the main results of this two-year project.
“…In non-mechanical RCM, however, the pivoting motion is generated by virtue of coordinated control of multiple joints in high-DOF robots. For example, Dombre et al (42) reported a programmable RCM MIS robot used for endoscopy, Figure 9. The endoscopic instrument is held by the end-effector of the robot and is virtually pivoted at the trocar point by means of the computer-simulated trocar constraints.…”

“…Hence, a significant number of works have addressed robot-assisted enhancement of distal dexterity in MIS [2][3][4][5][6][7][8][9][10][11]. Of these works, few addressed the problem of dexterity enhancement in deep surgical fields [6,10,12].…”
This paper addresses the design considerations and dexterity evaluation of a novel hybrid two-armed micro-surgical slave robot equipped with intraocular dexterity devices. A unified framework for the kinematic modeling of this robot is presented while using the kinematic constraints stemming from the constrained motion of the eye. An augmented Jacobian describing the kinematics of the eye and the relative motion of each one of the two Intra-Ocular Dexterity Robots (IODR) is presented. Using this framework, the capabilities of this two-armed robot in performing dexterous intraocular operations are evaluated and compared to a similar robot without intra-ocular dexterity. The Kinematic Conditioning Index (KCI) for the proposed robot is shown to be significant. The results presented show an increase of approximately 33% and 47% in translational and rotational KCI respectively.
SUMMARYLaparoscopic and Single Port Access Surgery (SPAS) present unique dexterity challenges related to dual-arm operations in confined spaces and tele-manipulation of highly dexterous surgical slaves. In an effort to reduce tele-manipulation burden, new paradigms for semi-automating surgical tasks are needed. This paper presents a new minimal constraint suturing and automated choice of handedness for anthropomorphic dual-arm robots. The automated choice of handedness supports surgeons during tele-manipulation of complex robotic slaves where dexterity and workspace constraints are difficult to learn. This criterion is also used to support automated dual-arm rendezvous for quicker suture exchange during dual-arm suturing. The minimal constraint algorithm presented in this paper allows surgeons to operate within a shared-control tele-manipulation framework whereby the surgeon controls the needle insertion speed and the robot controls the needle orientation while respecting a minimalistic set of tissue constraints. This framework is evaluated on a novel insertable robotic end-effectors platform for SPAS. A simulation study demonstrates the effectiveness of the automated choice of handedness criterion through a study of dexterity limitations of each arm. Additional simulations show the proposed algorithm for automated rendezvous and suture exchange.
