Surgical stapling system comprising a lockable firing assembly

A surgical instrument system comprising a completely replaceable cartridge jaw is disclosed.

Surgical instrument including a drive assembly movable in a non-motorized mode of operation

A surgical instrument comprising a shaft, an end effector, a housing, a drive assembly, and a manually-driven actuator is disclosed. The end effector comprises a first jaw and a second jaw rotatable relative to the first jaw between an open position and a clamped position. The housing comprises a rotary input movable by a motor. The drive assembly is operably engaged with the rotary input. The drive assembly is movable by the motor in a motorized mode of operation to transition the second jaw toward the clamped position. The drive assembly is movable in a non-motorized mode of operation by the manually-driven actuator to permit a transition of the second jaw toward the open position to release tissue between the first jaw and the second jaw.

Surgical instrument with detection sensors

Aspects of the present disclosure are presented for a surgical instrument having one or more sensors at or a near an end effector and configured to aide in the detection of tissues and other materials and structures at a surgical site. The detections may then be used to aide in the placement of the end effector and to confirm which objects to operate on, or alternatively, to avoid. Examples of sensors include laser sensors used to employ Doppler shift principles to detect movement of objects at the surgical site, such as blood cells; resistance sensors to detect the presence of metal; monochromatic light sources that allow for different levels of absorption from different types of substances present at the surgical site, and near infrared spectrometers with small form factors.

Staple formation detection mechanisms

A surgical stapling instrument comprising an end effector, an RFID tag, and a control circuit is disclosed. The end effector comprises an anvil, a staple cartridge, and a contact assembly configured to contact tissue. The staple cartridge comprises staples removably stored therein. The anvil and the staple cartridge are configurable between an open configuration and a closed configuration. The RFID tag is configured to store information about the staple cartridge. The control circuit is operably coupled to the contact assembly. The control circuit is configured to interrogate the RFID tag to determine the information about the staple cartridge, transmit an electrical signal to tissue contacting the contact assembly, determine a characteristic of the tissue contacting the contact assembly based on the electrical signal, and change an operational parameter of the surgical stapling instrument based on the characteristic of the tissue.

Surgical robotic system

A surgical robotic system is disclosed to include an operating table, a plurality of robotic arms and surgical instruments, a user console, and a control tower. The plurality of robotic arms are mounted on the operating table and can be stowed folded under the table for storage. The user console has one or more user interface devices, which function as master devices to control the plurality of surgical instruments.

System for transmission of sensor data using dual communication protocol

Medical patient monitoring sensor devices including a disposable sensor assembly and a reusable pairing device are disclosed. The disposable sensor assembly can collect patient physiological data and provide power for the reusable pairing device. The reusable pairing device can establish wireless communication with a monitoring device. Once the reusable pairing device receives patient physiological data from the disposable sensor assembly, the reusable pairing device can wirelessly transmit the data to the computing device via the wireless communication.

Remote passive intermodulation detection using nearby transmissions

Remote detection of interference generated by Passive Inter-Modulation (PIM) may be performed by determining intermodulation product information for a plurality of transmitters, receiving downlink power information of the plurality of transmitters, determining, using the intermodulation product information and the downlink power information, a Weighted Downlink Power (WDP) signal for an intermodulation product, and determining, using the WDP signal and uplink interference information, a PIM Detection Assessment (PIMDA) score of the intermodulation product, the value of the PIMDA score corresponding to interference generated by PIM. The WDP signal includes a plurality of expected power values. The remote detection of the interference generated by PIM may be performed by a wireless telecommunications system comprising a receiver and a processor, wherein the uplink interference information is of the receiver.

System to monitor and manage patient hydration via plethysmograph variablity index in response to the passive leg raising

Techniques for predicting fluid responsiveness or fluid unresponsiveness are described. A processor can determine a first prediction of fluid responsiveness or unresponsiveness based on a plethysmograph variability parameter associated with a plethysmograph waveform, and can determine a second prediction of fluid responsiveness or unresponsiveness based on a fluid responsiveness parameter that is associated with an elevation of one or more limbs of the patient. The processor can determine an overall prediction of fluid responsiveness or unresponsiveness based on the first and/or second predictions. Based on overall prediction, the processor can cause administration of fluids and/or termination of administration of fluids.

Methods for depositing a boron doped silicon germanium film

A method for depositing a boron doped silicon germanium (Si1-xGex) film is disclosed. The method may include: providing a substrate within a reaction chamber; heating the substrate to a deposition temperature; flowing a silicon precursor, a germanium precursor, and a halide gas into the reaction chamber through a first gas injector; flowing a boron dopant precursor into the reaction chamber through a second gas injector independent from the first gas injector; contacting the substrate with the silicon precursor, the germanium precursor, the halide gas and the boron dopant precursor; and depositing the boron doped silicon germanium (Si1-xGex) film over a surface of the substrate.

Methods for selectively depositing an amorphous silicon film on a substrate

A method for selectively depositing an amorphous silicon film on a substrate comprising a metallic nitride surface and a metallic oxide surface is disclosed. The method may include; providing a substrate within a reaction chamber, heating the substrate to a deposition temperature, contacting the substrate with silicon iodide precursor, and selectively depositing the amorphous silicon film on the metallic nitride surface relative to the metallic oxide surface. Semiconductor device structures including an amorphous silicon film deposited by selective deposition methods are also disclosed.
