| 20080255585 | Resiliently deformable tool guide for use in minimally invasive telesurgical system - A tool guide for guiding an end effector of a robotically controlled surgical instrument from a position outside a patient body to a position in close proximity to an internal surgical site within the patient body is provided. The tool guide typically comprises a body, a seat formation on the body, the seat formation being arranged to seat in an aperture leading into the patient body so as to mount the tool guide on the patient body, and a sheath formation on the body. The sheath formation typically defines a longitudinally extending internal passage, an inlet leading into the passage and an outlet leading from the passage. The sheath formation is arranged to cooperate with the seat formation such that when the seat formation is seated in the aperture, the outlet of the sheath formation can be positioned in close proximity to the internal surgical site thereby to enable the end effector to be guided to a position in close proximity to the surgical site by passing it through the inlet, along the passage and out from the outlet, so as to emerge from the outlet at the position in close proximity to the internal surgical site. | 10-16-2008 |
| 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.

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 |
| 20100228284 | SURGICAL TOOL HAVING POSITIVELY POSITIONABLE TENDON-ACTUATED MULTI-DISK WRIST JOINT - The present invention is directed to a tool having a wrist mechanism that provides pitch and yaw rotation in such a way that the tool has no singularity in roll, pitch, and yaw. A positively positionable multi-disk wrist mechanism includes a plurality of disks or vertebrae stacked in series. Each vertebra is configured to rotate in pitch or in yaw with respect to each neighboring vertebra. Actuation cables are used to manipulate and control movement of the vertebrae. In specific embodiments, some of the cables are distal cables that extend from a proximal vertebra through one or more intermediate vertebrae to a distal vertebra, while the remaining cables are medial cables that extend from the proximal vertebra to one or more of the intermediate vertebrae. The cables are actuated by a pivoted plate cable actuator mechanism. In specific embodiments, the actuator mechanism includes a plurality of small radius holes or grooves for receiving the medial cables and a plurality of large radius holes or grooves for receiving the distal cables. The holes or grooves restrain the medial cables to a small radius of motion and the distal cables to a large radius of motion, so that the medial cables to the medial vertebra move only a fraction of the amount as the distal cables to the distal vertebra, so as to achieve precise control and manipulation of the vertebrae. | 09-09-2010 |
| 20100274281 | PLUG WITH DETACHABLE GUIDEWIRE ELEMENT AND METHODS FOR USE - An apparatus for sealing a passage through tissue includes a bioabsorbable, threaded plug carried by a delivery device. A guide wire is receivable through lumens in the plug and delivery device that includes wings on a bioabsorbable distal portion. With the wings collapsed, the guide wire is advanced through the passage into a blood vessel, the wings expanding once located within the vessel, and the guide wire is withdrawn until the wings contact the vessel wall. The plug is threaded into the passage over the guide wire until the plug is disposed adjacent the wings. The distal portion of the guide wire is secured to the plug, e.g., by compressing a collet within the plug lumen that seals the lumen, and is severed from a proximal portion thereof. Thus, the plug and distal portion are deployed with the plug sealing the passage. | 10-28-2010 |
