20220192768 | ROBOTIC SURGERY SYSTEM AND METHOD FOR CONTROLLING SAME - A method for controlling, by means of an input unit, at least one manipulator arm of a robotic surgery system and an instrument held by the at least one manipulator arm. The input unit features a multi-linkage kinematic chain with active and/or passive joints and an open end. The open end is configured as a handpiece with at least one first passive joint. An operator controls movements of the instrument via moving the handpiece. The first passive joint features a first position sensor creating position signals which are used to control the movements of the instrument. A first measured value is calculated from a chronological succession of position signals of the first position sensor, and compared with a specified first threshold value. Control of the movement of the instrument is interrupted when the first measured value is smaller than the first threshold value. | 2022-06-23 |
20220192769 | SURGICAL INSTRUMENT AND MEDICAL MANUPULATOR SYSTEM - There is provided a surgical instrument having a plurality of methods of use and reducing the number of times that treatment portions are detachably replaced. The surgical instrument includes a treatment unit having a first treatment portion on an end portion thereof and a second treatment portion on another end portion thereof, and a holder that supports the treatment unit so as to allow the states of use of the first treatment portion and the second treatment portion to be switched. The holder supports the holder so as to be rotatable around a switching shaft for switching the states of use of the first treatment portion and the second treatment portion, and supports the treatment unit such that, while one of the first treatment portion and the second treatment portion is in a usable state, the other is in a standby state. | 2022-06-23 |
20220192770 | SYSTEM AND METHOD FOR ROBOTIC CART ARM ASSEMBLY IDENTIFICATION - A surgical robotic system includes a control tower having a first connector coupled to a first controller; and a movable robotic arm cart having a robotic arm and a second connector coupled to a second controller, the second connector being configured to couple to the first connector through a cable. The second controller being configured to transmit an identification signal having identification information of the movable robotic arm cart to the first controller to initialize the movable robotic arm cart for operation with the control tower. | 2022-06-23 |
20220192771 | EMULATION OF ROBOTIC ARMS AND CONTROL THEREOF IN A VIRTUAL REALITY ENVIRONMENT - A virtual reality system providing a virtual robotic surgical environment, and methods for using the virtual reality system, are described herein. The virtual reality system may be used to expedite the R&D cycle during development of a robotic surgical system, such as by allowing simulation of potential design without the time and significant expense of physical prototypes. The virtual reality system may also be used to test a control algorithm or a control mode for a robotic surgical component. | 2022-06-23 |
