Publication number: 20140371708Abstract: A surgical system includes a first instrument defining a first channel and a second instrument receivable by the first channel. The second instrument defines a second channel. A valve coupled to the first instrument controls fluid flow through the first channel, such that impedance of fluid flow through the first channel is substantially the same without the second instrument received in the first channel and with the first channel partially blocked by the second instrument. In another aspect, a surgical apparatus includes an outer member and an inner member received within the outer member to define a first channel therebetween. The inner member houses an optical lens and defines a second channel for receiving a surgical instrument. The first and second channels are configured such that a pump having an inflow rate of up to about 0.7 L/min connected to the second channel can maintain fluid pressure inside an organ.Type: ApplicationFiled: August 29, 2014Publication date: December 18, 2014Inventors: Cemal Shener-Irmakoglu, Christopher R.

Publication number: 20140066965Abstract: A dual function arthroscopic blade provides multiple cutting surfaces of differing cut aggressiveness for selective engagement of the desired cutting blade without retracting the instrument for changing cutting members to apply a different set of cutting edges, or blade. An inner rotating member within a stationary outer cutting member provide cutting edges defined by cutting windows on the inner and outer cutting members, and a rotational drive applies an oscillating rotation such that one of the cutting windows, corresponding to one of the sets of cutting edges, engages an extraction region such as tissue or bone. The use of different sized cutting windows allows variance in the aggressiveness of the cut, and allows selection of another cutting window by rotating the cutting member to align the selected cutting edges without requiring extraction and reinsertion in order to attach a different blade with a different cut aggressiveness.Type: ApplicationFiled: November 4, 2013Publication date: March 6, 2014Applicant: Smith & Nephew, Inc.Inventors: Petter A.

Publication number: 20100063625Abstract: A robot control system includes a line tracking encoder that measures a reference position of a conveyor line and transmits a tracking signal representing tracking data including the reference position of the conveyor line. A master controller is in communication with the encoder to receive the tracking signal, process the tracking data represented by the tracking signal, and generate a data packet in response to processing of the tracking data. A slave controller is in communication with the master controller and at least one robot for receiving the data packet and controlling the movement of the at least one robot in response to the data packet. A communications network directly interconnects the master controller and the slave controller and transmits the data packet from the master controller to the slave controller.Type: ApplicationFiled: September 5, 2008Publication date: March 11, 2010Inventors: Kenneth W.
