| 20100145521 | ROBOTIC SURGICAL SYSTEM WITH JOINT MOTION CONTROLLER ADAPTED TO REDUCE INSTRUMENT TIP VIBRATIONS - A robotic surgical system has a robot arm holding an instrument for performing a surgical procedure, and a control system for controlling movement of the arm and its instrument according to user manipulation of a master manipulator. The control system includes a filter in its forward path to attenuate master input commands that may cause instrument tip vibrations, and an inverse filter in a feedback path to the master manipulator configured so as to compensate for delay introduced by the forward path filter. To enhance control, master command and slave joint observers are also inserted in the control system to estimate slave joint position, velocity and acceleration commands using received slave joint position commands and torque feedbacks, and estimate actual slave joint positions, velocities and accelerations using sensed slave joint positions and commanded slave joint motor torques. | 06-10-2010 |
| 20100198215 | IN VIVO ACCESSORIES FOR MINIMALLY INVASIVE ROBOTIC SURGERY - Surgical accessories are presented in vivo and used by surgical tools in the surgical site to perform additional tasks without the need to remove the tools from the surgical site for tool change or instrument loading. Examples of in vivo accessories include fastening accessories such as surgical clips for use with a clip applier, single working member accessories such as a blade which can be grasped and manipulated by a grasping tool for cutting, sheath accessories that fit over working members of a tool, flow tubes for providing suction or introducing a fluid into the surgical site, and a retraction member resiliently biased to retract a tissue to expose an area in the surgical site for treatment. The accessories can be introduced into the surgical site by a dedicated accessory introducer, or can be supported on the body of a surgical tool inserted into the surgical site and be manipulated using another surgical tool in the surgical site. The accessory introducer can be resiliently biased to bias the accessories toward a predetermined position in the surgical site. | 08-05-2010 |
| 20100234857 | MEDICAL ROBOTIC SYSTEM WITH OPERATIVELY COUPLABLE SIMULATOR UNIT FOR SURGEON TRAINING - A medical robotic system has a surgeon console which is operatively couplable to a patient side unit for performing medical procedures or operatively couplable to a simulator unit for training purposes. The surgeon console has a monitor, input devices and foot pedals. The patient side unit has robotic arm assemblies coupled to instruments and an endoscope. When the surgeon console is coupled to the patient side unit, the instruments move in response to movement of the input devices to perform a medical procedure while captured images of the instruments are displayed on the monitor. When the surgeon console is coupled to the simulator unit, virtual instruments move in response to movement of the input devices to perform a user selected virtual procedure while virtual images of the virtual instruments are displayed on the monitor. | 09-16-2010 |
| 20110028991 | Cardiac Tissue Ablation Instrument with Flexible Wrist - An articulate minimally invasive surgical instrument with a flexible wrist to facilitate the safe placement and provide visual verification of the ablation catheter or other devices in Cardiac Tissue Ablation (CTA) treatments is described. In one embodiment, the instrument is an endoscope which has an elongate shaft, a flexible wrist at the working end of the shaft, and a vision scope lens at the tip of the flexible wrist. The flexible wrist has at least one degree of freedom to provide the desired articulation. It is actuated and controlled by a drive mechanism located in the housing at the distal end of the shaft. The articulation of the endoscope allows images of hard-to-see places to be taken for use in assisting the placement of the ablation catheter on the desired cardiac tissue. The endoscope may further include couplings to releasably attach an ablation device/catheter or a catheter guide to the endoscope thereby further utilizing the endoscope articulation to facilitate placement of the ablation catheter on hard-to-reach cardiac tissues. In another embodiment, the articulate instrument is a grasper or any other instrument with a flexible wrist and a built-in lumen to allow an endoscope to insert and be guided to the distal end of the instrument. | 02-03-2011 |
| 20110105898 | Real-Time Generation of Three-Dimensional Ultrasound image using a Two-Dimensional Ultrasound Transducer in a Robotic System - Systems and methods for performing robotically-assisted surgical procedures on a patient enable an image display device to provide an operator with auxiliary information related to the surgical procedure, in addition to providing an image of the surgical site itself. The systems and methods allow an operator to selectively access and reference auxiliary information on the image display device during the performance of a surgical procedure. | 05-05-2011 |
| 20110137322 | Cooperative Minimally Invasive Telesurgical System - Improved robotic surgical systems, devices, and methods include selectably associatable master/slave pairs, often having more manipulator arms than will be moved simultaneously by the two hands of a surgeon. Four manipulator arms can support an image capture device, a left hand tissue manipulation tool, a right hand tissue manipulation tool, and a fourth surgical instrument, particularly for stabilizing, retracting, tool change, or other functions benefiting from intermittent movement. The four or more arms may sequentially be controlled by left and right master input control devices. The fourth arm may be used to support another image capture device, and control of some or all of the arms may be transferred back-and-forth between the operator and an assistant. Two or more robotic systems each having master controls and slave manipulators may be coupled to enable cooperative surgery between two or more operators. | 06-09-2011 |
| 20120022553 | Side Looking Minimally Invasive Surgery Instrument Assembly - Two surgical instruments are inserted through a guide tube. The surgical instruments exit at an intermediate position of the guide tube and are oriented to be substantially parallel to the guide tube's longitudinal axis as they exit. A stereoscopic image capture component is on the guide tube between the intermediate position and the guide tube's distal end. The image capture component's field of view is generally perpendicular to the guide tube's longitudinal axis. The surgical instruments and the guide tube are telemanipulatively controlled. | 01-26-2012 |
