Surgical system

A surgical instrument configured to be coupled to a robotic surgical system is disclosed. The surgical instrument comprises an end effector, a threaded drive shaft, a firing member drivable by the threaded drive shaft, a closure system configured to move a iaw of the end effector toward a closed position, and a housing assembly coupleable with the robotic surgical system and comprising an array of electrical contacts. The surgical instrument further comprises a first motor configured to drive the closure system, a second motor configured to drive the threaded drive shaft, a first decoupleable electrical contact configured to supply power to the first motor from a power system, and a second decoupleable electrical contact configured to supply power to the second motor from the power system. The power system is selectively interrupted unless a signal is provided to the power system from the robotic surgical system.

Surgical stapling system including a flexible firing actuator and lateral buckling supports

A surgical instrument that includes an elongate channel that is configured to operably support a surgical staple cartridge therein. In at least one form, an anvil is pivotally coupled to a proximal end of the elongate channel such that the anvil is pivotal about a discrete, non-movable anvil axis defined by the elongate channel. A firing member is configured for axial travel within the elongate channel in response to an application of firing motions thereto. The firing member is configured to movably engage the anvil and the elongate channel to space the anvil relative to the elongate channel at a desired spacing as the firing member is axially driven through the elongate channel. A closure member is configured to move the anvil from an open position to closed positions relative to the elongate channel upon application of closure motions to the closure member.

Hybrid lift pin

A lift pin and a substrate support assembly and reactor including the lift pin are disclosed. The lift pin includes first section comprising a material having a first transparency and a second section comprising a material having a second transparency. The lift pin can provide improved temperature uniformity across substrate support assembly including the lift pin during substrate processing.

Navigation of tubular networks

Methods and apparatuses provide improved navigation through tubular networks such as lung airways by providing improved estimation of location and orientation information of a medical instrument (e.g., an endoscope) within the tubular network. Various input data such as image data, EM data, and robot data are used by different algorithms to estimate the state of the medical instrument, and the state information is used to locate a specific site within a tubular network and/or to determine navigation information for what positions/orientations the medical instrument should travel through to arrive at the specific site. Probability distributions together with confidence values are generated corresponding to different algorithms are used to determine the medical instrument's estimated state.

ENDOSCOPIC DEVICE WITH HELICAL LUMEN DESIGN

An endolumenal robotic system provides the surgeon with the ability to drive a robotically-driven endoscopic device to a desired anatomical position in a patient without the need for awkward motions and positions, while also enjoying improved image quality from a digital camera mounted on the endoscopic device.

Systems and methods for assisting patient airway management

A medical system for assisting with an intubation procedure for a patient. The system comprising airflow sensors configured to obtain data indicative of airflow in the patient's airway and physiological sensors configured to obtain information regarding airflow in the patient's lungs. The system further including a monitoring device communicatively coupled to the airflow sensors and the physiological sensors. The patient monitoring device comprising at least one processor coupled to memory and configured to: provide a user interface on a display and assist the rescuer in determining proper placement of an endotracheal tube, receive the data indicative of the airflow in the patient's airway, receive the physiological information regarding the airflow in the patient's lungs, and determine whether the tube is properly placed based on the received physiological information, and present an output of the determination of whether the ET tube was properly placed.

Well fracturing systems with electrical motors and methods of use

A system for stimulating oil or gas production from a wellbore includes a hydraulic fracturing pump unit having one or more hydraulic fracturing pumps driven by one or more electrical fracturing motors, a variable frequency drive (VFD) controlling the electrical fracturing motors, a fracturing pump blower unit driven by a blower motor, and a fracturing pump lubrication unit having a lubrication pump driven by a lubrication motor and a cooling fan driven by a cooling motor. The system may further include a blender unit and a hydration unit. A system control unit may control the operational parameters of the system.

Intra-cardiac scar tissue identification using impedance sensing and contact measurement

A system includes an electrical interface and a processor. The electrical interface is configured for communicating with a probe inserted into a heart of a patient. The processor is configured to receive, via the electrical interface, (i) a first indication of an electrical impedance measured by the probe at a given location on an inner surface of the heart, and (ii) a second indication of a quality of mechanical contact between the probe and the inner surface of the heart during measurement of the electrical impedance. The processor is further configured, based on the first and second indications, to classify tissue at the given location as scar tissue.

Devices, methods, and graphical user interfaces for system-wide behavior for 3D models

A computer system having a display generation component, one or more input devices, and one or more cameras receives a request to display a virtual object in a first user interface region that includes a field of view of the one or more cameras. In response to the request, in accordance with a determination that object-placement criteria are not met, the representation of the virtual object is displayed with a first set of visual properties and with a first orientation that is independent of which portion of the physical environment is displayed in the field of view of the one or more cameras. In accordance with a determination that the object-placement criteria are met, the representation of the virtual object is displayed with a second set of visual properties that are distinct from the first set of visual properties and with a second orientation that corresponds to a plane.
