Publication number: 20240115325Abstract: A camera tracking system for computer assisted navigation during surgery. Operations identify locations of markers of a reference array in images obtained from tracking cameras imaging a real device. Operations determine measured coordinate locations of a feature of a real device in the images based on the identified locations of the markers and based on a relative location relationship between the markers and the feature. Operations process a region of interest in the images identified based on the measured coordinate locations through a neural network configured to output a prediction of coordinate locations of the feature in the images. The neural network has been trained based on training images containing the feature of a computer model rendered at known coordinate locations. Operations track pose of the feature of the real device in 3D space based on the prediction of coordinate locations of the feature of the real device in the images.Type: ApplicationFiled: October 11, 2022Publication date: April 11, 2024Inventors: Thomas Calloway, Sanjay Joshi, Tushar Sawant, Rand Kmiec, Norbert Johnson

Publication number: 20240065707Abstract: A system of robotic surgery includes components capable of drilling a bore in the cranium of a patient in connection with craniotomy and other cranial surgeries. A perforator associated with such system is controlled by suitable computer-implemented instructions to maintain the perforator tip along a desired trajectory line while moving the perforator bit at locations proximal to such perforator tip in a circular motion, thereby imparting a conical oscillation to the perforator bit relative to the trajectory line. The angle at which the perforator bit is oscillated relative to such trajectory line results in the bore formed in the cranium having a diameter larger than the bit diameter, and the larger diameter and related conical oscillation is selected so as to reduce frictional force opposing withdrawal of the bit from the situs of the bore, thereby reducing the risk of jamming of the bit during its associated operations.Type: ApplicationFiled: June 28, 2023Publication date: February 29, 2024Inventors: Hayden Cameron, Spiros Mantzavinos, Neil R.

Patent number: 11850012Abstract: A system for robotic surgery makes use of an end-effector which has been configured so that any selected one of a group of surgical tools may be selectively connected to such end-effector. The end-effector makes use of a tool-insert locking mechanism which secures a selected one of the surgical tools at not only a respective, predetermined height and angle of orientation, but also at a rotational position relative to an anatomical feature of the patient. The tool-insert locking mechanism may include interchangeable inserts to interconnect multiple tools to the same end-effector. In this way, different robotic operations may be accomplished with less reconfiguration of the end-effector. The end-effector may also include a tool stop which has a sensor associated with a moveable stop mechanism which may be positioned to selectively inhibit tool insertion or end-effector movement.Type: GrantFiled: March 31, 2022Date of Patent: December 26, 2023Inventors: Hayden Cameron, Spiros Mantzavinos, Neil R.

Publication number: 20220368122Abstract: Analog Front End (AFE) driver or transmitter is used for ESD protection of an input-output (IO) pin, thus reducing ESD diode count and subsequently lowering the pad capacitance to achieve high performance in IO circuits like double data rate (DDR) TO, PCI Express (Peripheral Component Interconnect Express), etc. The channel of active devices that constitute AFE driver are used to connect an IO pad to discharge the ESD current to ground, thus providing an alternative path to ESD current and subsequently reducing the ESD diode count. An additional p-type device (Driver Path Enabler (DPE)) is coupled between the IO pad and a gate terminal of the AFE driver. This additional p-type device triggers the channel of the AFE driver. This p-type device is controlled by an RC based structure which cuts the p-type device off during regular operations when power is ramped-up.Type: ApplicationFiled: July 28, 2022Publication date: November 17, 2022Inventors: Raj Singh Dua, Sanjay Joshi, Harry Muljono, Balkaran Gill
