摘要:
In one embodiment of the invention, a robotic surgical instrument is provided for the control of flows of one or more fluids into and out of a surgical site. The robotic surgical instrument may include a housing, a flow control system, a hollow tube, and one or more hose fittings. The housing to couple the instrument to a robotic arm. The flow control system mounted in the housing includes one or more controlled valves to control the flow of one or more fluids. The hollow tube has a first end mounted in the housing coupled to the flow control system. A second end of the hollow tube has one or more openings to allow the flow of fluids into and out of the surgical site. The hose fittings have a first end coupled to the flow control system and a second end to couple to hoses.

The present invention provides an integrated high voltage capacitor, a method of manufacture therefore, and an integrated circuit chip including the same. The integrated high voltage capacitor, among other features, includes a first capacitor plate (120) located over or in a semiconductor substrate (105), and an insulator (130) located over the first capacitor plate (120), at least a portion of the insulator (130) comprising an interlevel dielectric layer (135, 138, 143, or 148). The integrated high voltage capacitor further includes a second capacitor plate (160) located over the insulator (130).

Two or more minimally invasive surgical instruments are assembled in a magazine A first one of the instruments is inserted into and withdrawn from a guide tube, and then a second one of the surgical instruments is inserted into the guide tube in place of the first one of the instruments. Several magazines may be used, each magazine being configured with all instruments necessary to perform different surgical procedures.
摘要:
A guide tube for a minimally invasive surgical system has a single channel that accepts two or more surgical instruments. The channel has two or more bores, and a body segment of each instrument extends through a unique one of the bores. A slot connects two of the bores along the length of the channel. A distal component of one of the instruments is larger than the instrument's bore, and so the component slides through the slot, and in some aspects through some or all of the other bore, as the instrument is inserted through the guide tube. After the instrument has been inserted, a second instrument can then be inserted through the other bore.

A telemanipulatively controlled guide tube acts as a wrist mechanism for a surgical instrument that extends through the guide tube. The instrument may be removed and replaced with another instrument. In some aspects the instruments are commercial, off the shelf minimally invasive surgical instruments.

A medical robotic system provides 3D telestration over a 3D view of an anatomical structure by receiving a 2D telestration graphic input associated with one of a pair of stereoscopic images of the anatomical structure from a mentor surgeon, determining a corresponding 2D telestration graphic input in the other of the pair of stereoscopic images using a disparity map, blending the telestration graphic inputs into respective ones of the pair of stereoscopic images, and providing the blended results to a 3D display so that a 3D view of the telestration graphic input may be displayed as an overlay to a 3D view of the anatomical structure to an operating surgeon.

In one embodiment of the invention, a robotic surgical system is provided including a master control console and a surgical manipulator. The master control console generates control signals to cause one or more fluids to flow into or out of a surgical site. The surgical manipulator is coupled to the console to receive the control signals and includes at least one robotic arm and a surgical instrument coupled thereto. The surgical manipulator controls the surgical instrument in response to the control signals to control the flow of the one or more fluids into or out of the surgical site. The surgical instrument has a first robotically controlled valve that is responsive to the surgical manipulator and a hollow tube having a first end coupled to the first robotically controlled valve with an opening at a second end to direct the flow of one or more fluids.

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.

A process for producing lube oil basestocks wherein a wax containing lube oil boiling range feedstream is converted into a basestock suitable for use in motor oil applications by contacting it with a hydrodewaxing catalyst containing a medium pore molecular sieve having deposited thereon an active metal oxide and at least one hydrogenation metal selected from the Group VIII and Group VIB metals.
