Publication number: 20230056674Abstract: Surgical systems, navigation systems, and methods involving a robotic manipulator configured to control movement of an instrument to facilitate a surgical procedure. The navigation system includes a camera unit configured to optically track a pose of the instrument and a non-optical sensor coupled to the instrument. The navigation system includes a computing system coupled to the camera unit and being configured to obtain readings from the non-optical sensor. The computing system detects a condition whereby the camera unit is blocked from optically tracking the pose of the instrument. In response to detection of the condition, the computing system tracks the pose of the instrument with the readings from the non-optical sensor.Type: ApplicationFiled: November 8, 2022Publication date: February 23, 2023Applicant: Stryker CorporationInventor: Chunwu Wu

Patent number: 11529198Abstract: Systems and methods are disclosed that utilize a robotic device supporting and moving a cutting tool in at least three degrees of freedom. A control system commands the robotic device to control or constrain movement of the cutting tool. A first tracker is coupled to the robotic device and a second tracker is coupled to an anatomy. The second tracker includes three markers that generate optical signals and a non-optical sensor that generates non-optical signals. A navigation system with an optical sensor is in communication with the control system. The navigation system receives, with the optical sensor, the optical signals from one or more of the three markers and receives the non-optical signals from the non-optical sensor. The navigation system communicates position data indicative of a position of the anatomy to the control system to control cutting of the anatomy based on the received optical and non-optical signals.Type: GrantFiled: February 6, 2020Date of Patent: December 20, 2022Assignee: Stryker CorporationInventor: Chunwu Wu

Publication number: 20220125401Abstract: A system is disclosed for determining a position and a change in the position of an anatomical structure. The system utilizes a surgical navigation system and a substrate that is capable of being removably mounted to an outer surface of a body. A sensor is attached to the substrate to be tracked by the surgical navigation system. An ultrasonic imaging device is attached to the substrate to determine a position of the anatomical structure. A first circuit calculates a global position of the anatomical structure by correlating a position of the sensor and the position of the anatomical structure. The first circuit determines the global position without the use of an image of the anatomical structure, and may do so without the use of a reference device invasively affixed to the body. A second circuit displays the global position of the anatomical structure.Type: ApplicationFiled: January 10, 2022Publication date: April 28, 2022Applicant: Stryker European Operations Holdings LLCInventors: José Luis Moctezuma de la Barrera, Chunwu Wu

Patent number: 8905413Abstract: A system for collecting and compressing waste collected in a medical or surgical procedure. The system includes a bag for collecting the waste that is seated on a mobile cart. Once the waste is collected the bag is closed and, while on the cart, transported to a compactor. While on the cart, the bag is compacted. Air in the bag is discharged through a one-way valve fitted to the bag. The one way valve may be attached to a cartridge that is inserted into the bag opening. The air discharged from the bag is filtered prior to discharge into the ambient environment. The filter may be built into the one-way valve.Type: GrantFiled: July 31, 2013Date of Patent: December 9, 2014Assignee: Stryker CorporationInventors: Bruce Henniges, Douglas L. Tyler, James G.
