Surgical device including a control system

A surgical device comprising a staple cartridge, a clamping mechanism configured to clamp patient tissue, a firing member, a manual bailout, an electric motor, a power source, and a control unit is disclosed. The clamping mechanism comprises a first iaw and a second iaw. The firing member configured to engage the first jaw and the second jaw during a closure stroke. The second jaw is moved to the closed position during the closure stroke and the firing member is further configured to eject staples from the staple cartridge during a firing stroke. The manual bailout is configured to retract the firing member through a retraction stroke. The electric motor is configured to drive the firing member. The control unit is configured to monitor a parameter of the electric motor and control the amount of current supplied to the electric motor based on the parameter.

Detachable motor powered surgical instrument

A surgical instrument comprising a handle, a motor configured to output a rotary motion, a drive system operably responsive to the rotary motion, a power source configured to supply power to the motor, an end effector, a firing member operably responsive to the drive system, and means for monitoring the current supplied to the motor and limiting the current supplied to the motor when the current draw exceeds a predetermined threshold is disclosed.

Surgical device including a control system

A surgical device comprising a first clamping member, a second clamping member, an electric motor, and a control system is disclosed. The electric motor is configured to drive at least one of the first clamping member and the second clamping member toward a predetermined tissue gap between the first clamping member and the second clamping member to clamp the tissue of a patient. The control system is configured to monitor a parameter of the electric motor. The parameter is indicative of a clamping force exerted to the tissue by the first clamping member and the second clamping member. The control system is further configured to control the electric motor based on the parameter to limit the clamping force to a predetermined maximum limit.

Surgical instrument including a control module for assessing an end effector

A surgical instrument for use with a robotic system that has a control unit and a shaft portion that includes an electrically conductive elongated member that is attached to a portion of the robotic system. The elongated member is configured to transmit control motions from the robotic system to an end effector.

Surgical instrument for assessing the state of a staple cartridge

A surgical stapling instrument comprising a handle, an elongate shaft, an end effector, a motor couplable with a supply of current, a firing member operably responsive to the motor, a current sensor, and a control circuit is disclosed. The firing member is movable from a proximal position to a distal position during a firing stroke. The control circuit comprises a processor and a memory configured to store instructions which, when executed from the memory cause the processor to activate the motor in response to an actuation input, receive an input from the current sensor regarding the current draw of the motor, deactivate the motor when the current draw of the motor exceeds a threshold current when the firing member is within a threshold distance relative to the proximal position, and retract the firing member to the proximal position.

Surgical device

A surgical device is provided that includes a jaw portion with a first jaw and a second jaw moveable relative to the first jaw. The surgical device also includes a shaft portion coupled to a proximal end of the jaw portion. A driver is configured to cause relative movement of the jaw portion and the shaft portion. The driver may be configured to cause the jaw portion to pivot relative to the shaft portion about a pivot axis that is perpendicular to first and second longitudinal axes defined by the jaw portion and the shaft portion, respectively. The driver may also be configured to cause at least a portion of the jaw portion to rotate relative to the shaft portion about the first longitudinal axis. Advantageously, the surgical device includes a surgical member, e.g., a cutting element and/or a stapling element, disposed within the first jaw.

Bipolar electrosurgical hand shears

An apparatus comprises a first jaw, a second jaw, a first handle, and a second handle. The second jaw is pivotally coupled with the first jaw. The first jaw and the second jaw are configured to grasp tissue. The jaws provide offset electrode surfaces that are operable to deliver bipolar RF energy to tissue grasped between the jaws. The apparatus is further operable to sever tissue. A lockout feature selectively prevents tissue severing, based on an energization state of the jaws.

Wearable pulse oximeter and respiration monitor

A wireless patient monitoring device can be fully functional stand-alone patient monitoring device capable of various physiological measurements. The patient monitoring device is small and light enough to be comfortably worn on the patient, such as on the patient's wrist or around the neck. The patient monitoring device can have a monitor instrument removably engaging a disposable base. The base can have outlets for connecting to an acoustic respiration sensor and an oximeter sensor. The patient monitoring device can have pogo pin connectors connecting the monitor instrument and the disposable base so that the monitor instrument can receive sensor data from the sensors connected to the disposable base.

Secure and zero knowledge data sharing for cloud applications

Disclosed is a zero-knowledge distributed application configured to securely share information among groups of users having various roles, such as doctors and patients. Confidential information may be encrypted client-side, with private keys that reside solely client side. Encrypted collections of data may be uploaded to, and hosted by, a server that does not have access to keys suitable to decrypt the data. Other users may retrieve encrypted data from the server and decrypt some or all of the data with keys suitable to gain access to at least part of the encrypted data. The system includes a key hierarchy with multiple entry points to a top layer by which access is selectively granted to various users and keys may be recovered.

Organic reactants for atomic layer deposition

A method for selectively depositing a metal oxide film is disclosed. In particular, the method comprises pulsing a metal or semi-metal precursor onto the substrate and pulsing an organic reactant onto the substrate. A reaction between the metal or semi-metal precursor and the organic reactant selectively forms a metal oxide film on either a dielectric layer or a metal layer.
