  • Publication number: 20070013336
    Abstract: Telerobotic, telesurgical, and/or surgical robotic devices, systems, and methods employ surgical robotic linkages that may have more degrees of freedom than an associated surgical end effector n space. A processor can calculate a tool motion that includes pivoting of the tool about an aperture site. Linkages movable along a range of configurations for a given end effector position may be driven toward configurations which inhibit collisions. Refined robotic linkages and method for their use are also provided.

  • Publication number: 20060258938
    Abstract: Methods and system perform tool tracking during minimally invasive robotic surgery. Tool states are determined using triangulation techniques or a Bayesian filter from either or both non-endoscopically derived and endoscopically derived tool state information, or from either or both non-visually derived and visually derived tool state information. The non-endoscopically derived tool state information is derived from sensor data provided either by sensors associated with a mechanism for manipulating the tool, or sensors capable of detecting identifiable signals emanating or reflecting from the tool and indicative of its position, or external cameras viewing an end of the tool extending out of the body. The endoscopically derived tool state information is derived from image data provided by an endoscope inserted in the body so as to view the tool.

  • Publication number: 20050042470
    Abstract: The present invention provides a method of adhering two or more components together by exposing a first component that includes cellulose ester fibers and/or a second component that includes a cellulose ester to a plasticizing solvent. The two components are then contacted together form a compound structure which is subsequently allowed to cure so that the two components are bonded together. The present invention is advantageously utilized to form a filter and in particular a cigarette filter and to form a multilayer automobile headliner. The present invention also provides a method of adhering a cellulose ester-containing automobile headliner to a vehicle passenger compartment ceiling. In this embodiment, a cellulose ester-containing composition is applied to the vehicle compartment ceiling prior to attachment of the headliner. The headliner and/or the vehicle passenger compartment ceiling are then exposed to a plasticizing solvent, contacted together, and then cured thereby adhering the headliner.
