Apparatus for endoscopic procedures

A surgical device has a jaw assembly with a first jaw and a second jaw, a pivoting linkage, and a camming assembly configured to pivot the jaw assembly. A cam slot having a first portion, a second portion, and a third portion may have a Y shaped configuration. A flexible shaft allows further pivoting of the jaw assembly.

SAFETY LOCKOUT FOR SURGICAL STAPLER

A surgical stapling and cutting device is constructed with a knife safety lockout element to prevent a knife element from cutting tissue if staples cannot be applied first to the tissue prior to being cut. The surgical stapling and cutting device comprises of a staple holder for holding a staple cartridge, an anvil movably coupled to the staple holder for opposing and deforming staples, a knife safety lockout element for blocking a knife element from being deployed, and a safety spring element for activating or biasing the knife safety lockout element into an active state to block the knife element from being deployed.

Surgical instrument with tissue density sensing

An apparatus comprises an end effector, a body assembly, a power source, and a control module. The end effector is operable for use in a surgical procedure and can deliver energy to a surgical site. The end effector comprises at least one sensor. The sensor is able to measure at least one physical characteristic associated with the surgical site. The body assembly is in communication with the end effector. The power source is in communication with the body assembly and is operable to deliver power to the end effector. The control module is in communication with the sensor and is operable to change delivery of power to the end effector based on data from the sensor indicating a change in tissue density.

Surgical instrument buttress attachment

A surgical stapler instrument has surgical stapler jaws, at least one staple line reinforcement material, and a fastener including a hook and a loop. The hook can be disposed on one of the surgical stapler jaws and the loop can be disposed on the staple line reinforcement material. Alternatively, the hook can be disposed on the staple line reinforcement material and the look on one of the surgical stapler jaws.

Surgical stapling device for performing circular anastomoses

This application is directed to a surgical stapling device for performing circular anastomoses. The surgical stapling device includes a handle portion, an elongated body portion and a head portion including an anvil assembly and a shell assembly. A tactile indication mechanism is also provided for notifying a surgeon that the device has been fired and for notifying a surgeon that the anvil head has been unapproximated a distance sufficient to permit the anvil head to tilt.

Devices and techniques for cutting and coagulating tissue

Various forms are directed to systems and methods for driving an end effector coupled to an ultrasonic drive system of a surgical instrument. A generator may generate at least one electrical signal. The at least one electrical signal may be monitored against a first set of logic conditions. When an ultrasonic impedance of the surgical instrument exceeds a threshold impedance, a resonant frequency of the at least one electrical signal may be stored as a baseline frequency. A first response of the generator may be triggered upon the occurrence of either the first set of logic conditions being met or the resonant frequency of the at least one electrical signal differing from the baseline frequency by a baseline deviation threshold.

3D POSITIONING OF AUGMENTED REALITY INFORMATION

A system and method for providing informational labels with perceived depth in the field of view of a user of a head mounted display device. In one embodiment, the method includes determining a physical location of the user and the head mounted display device, and identifying and determining a distance from the user to one or more objects of interest in the user's field of view. Using the distance from the user for each object, one can calculate a disparity value for viewing each object. The processor of the head mounted device may gather information concerning each of the objects in which the user is interested. The head mounted display device then provides a label for each of the objects and for each eye of the user, and, using the disparity values, places the labels within the field of view of the user.

Clip applier adapted for use with a surgical robot

A clip applier adapted for use with a surgical robot. The clip applier includes a shaft having clips stored therein and jaws adapted for receiving a clip from the shaft. The shaft is in mechanical communication with a robotic mounting portion that is adapted for mounting to a surgical robot. The robotic mounting portion contains a gear drive assembly for independently rotating the shaft, feeding clips into the jaws and forming clips in the jaws.

Nonvolatile memory devices, channel boosting methods thereof, programming methods thereof, and memory systems including the same

Non-volatile memory device channel boosting methods in which at least two strings are connected to one bit line, the channel boosting methods including applying an initial channel voltage to channels of strings in a selected memory block, floating inhibit strings each having an un-programmed cell among the strings, and boosting channels of the floated inhibit strings.

Accelerometer-controlled master power switch for electronic devices

An accelerometer or other motion sensor is used to provide power to an entire processor system such that the processor does not need to be powered to process the motion signals for initial power-on control. After the processor system is powered on, the processor system may receive and process motion signals as normal, including, for example, performing various power-control functions such as power-down of certain components or the entire system upon detection of a lack of motion for a predetermined amount of time.
