Motorized surgical instrument

A surgical cutting and fastening instrument that is motorized. The instrument comprises in one embodiment a charge accumulator device, separate from a battery, that provides additional power to the motor under certain conditions. In addition, the motor may comprise multiple windings.

Surgical stapling apparatus

Disclosed is a disposable surgical stapling unit configured for use with an actuation device that has an elongated shaft assembly. The disposable surgical stapling unit may include a housing assembly and a staple cartridge carrier configured to operably support a staple cartridge, and a drive member operably supported within the staple cartridge carrier. The drive member may comprise a cutting edge to cut tissue and a proximal end configured for operable engagement with a control member operably supported within the elongated shaft assembly. The disposable surgical stapling unit may further include articulation joints operably supported between the housing assembly and the staple cartridge carrier for selectively articulating the staple cartridge carrier about multiple articulation axes.

Motor-driven surgical cutting and fastening instrument with tactile position feedback

A surgical instrument is disclosed. The surgical instrument comprises a motor, an end effector, a drive shaft, and a closure trigger, wherein actuation of the closure trigger causes the end effector to clamp an object. The surgical instrument further comprises a firing trigger distinct from the closure trigger for actuating the motor, a run motor sensor capable of communicating with the motor and configured to sense actuation of the firing trigger, and a tactile feedback system for applying a feedback force to the firing trigger.

Video display modification based on sensor input for a see-through near-to-eye display

This disclosure concerns a near field communication (NFC) device which includes a wrist-worn NFC-enabled electronics device, wherein the wrist-worn NFC enabled electronics device includes a first communications link for communicating with a second NFC-enabled electronics device via NFC protocols, and a second communications link for communicating with an eyepiece via a medium-range communications protocol and receiving control commands. The wrist-worn NFC-enabled electronics device facilitates the transfer of data between the eyepiece and the second NFC-enabled electronics device. The eyepiece comprises optics enabling a see-through display on which is displayed the data.

Endoscopic surgical cutting stapler with a chain articulation

An endoscopic surgical cutting stapler with a chain articulation is provided, in which a joint is implemented by a chain articulation, teeth are provided at two ends of a chain plate of the chain articulation, and teeth of adjacent chain plates in the same row are engaged. Through mesh transmission of engaged teeth of the adjacent chain plates in the same row, an angle of a most proximal chain plate of the chain articulation is gradually multiplied at several stages and transmitted to an end effector. The end effector can rotate for 90° with small drive motion of the operating mechanism, thereby achieving precise placement of the chain articulation after rotation. The end effector can be precisely aligned with a part to be cut and stapled, and a radius of curvature of the chain articulation can be significantly increased.

FEATURES PROVIDING LINEAR ACTUATION THROUGH ARTICULATION JOINT IN SURGICAL INSTRUMENT

An apparatus for operating on tissue includes an end effector having a first jaw and a second jaw. The first jaw is configured to pivot relative to the second jaw from an open position to a closed position. The end effector also includes a blade member configured to translate within the end effector. An articulation portion is positioned between the end effector and a handpiece. The articulation portion is configured to bend to position the handpiece along a first longitudinal axis and the end effector along a second longitudinal axis. The articulation portion comprises a translation feature operable to translate the blade member.

Tamper-evident packaging

A tamper-evident package for pharmaceuticals is described. The package includes a case. A tray holding pharmaceuticals slides in and out of the case. The package includes an alarm that can be set to armed and triggered mode. When the alarm is armed, the system of the package changes the alarm to triggered in response to the tray being opened. The package may engage an access indicator in response to the alarm being triggered. The package may also flash an indicator light upon request, prior to opening the tray, to indicate whether the alarm was triggered since being previously armed. The alarm can be armed again if it is triggered, by entering a security code while the tray is closed.

Screw Tightening Tool

An screw tightening tool (1) includes: a handle part (22) to be held by a user; a trigger (25); a power supplying section (6, 7) that supplies an electrical power in accordance with an operated amount of the trigger; and a motor (3) that rotates in accordance with the electrical power supplied from the power supplying section. The power supplying section supplies the motor with a preventing electrical power for preventing the motor from rotating with respect to the handle part when a predetermined condition is satisfied.

OXIMETRIC PLETHYSMOGRAPHY

Systems and methods for estimating a plethysmograph waveform are provided. In some aspects, a system includes a detector module configured to receive, from a single channel, an oximeter output signal indicative of light absorption in a patient. The oximeter output signal includes infrared light components and red light components. The system also includes a processing module configured to determine an indicator of a ratio of (i) an indicator of at least one of the infrared light components to (ii) an indicator of at least one of the red light components. The processing module is configured to determine, based on the indicator of the ratio, an indicator of a plethysmograph waveform of the patient.

Robotic apparatus for minimally invasive surgery

A robotic arm especially suited for laparoscopic surgery, having a torsional joint and a flexural joint forming serially arranged joints is described. The joints provide respective degrees of freedom for the arm, which further receives drive means for such joints. The robotic arm also has transmission means placed between the drive means have and the joints. The transmission means a first and a second assembly of three gear wheels, preferably conical gear wheels, and a train of three additional gear wheels, preferably straight-cut gear wheels, which couple the first and second assembly to form a differential mechanism.
