Two-stage electrosurgical device for vessel sealing

A forceps includes an end effector assembly with a first jaw having a tissue sealing surface and an electrode on the sealing surface, and a second jaw having a tissue sealing surface and an electrode on the sealing surface. The first jaw and the second jaw move between an open position and a closed position. The sealing surface of at least one of the first jaw and the second jaw has a flexible medial section and rigid lateral sections.

SURGICAL DRILL AND METHOD OF CONTROLLING THE AUTOMATIC STOP THEREOF

A surgical drill includes a drill bit, a driving device connected and electrically coupled to the drill bit, and a smart module electrically coupled to the driving device. In a bone drilling work, the smart module monitors an electrical signal of the driving device, and if the electrical signal shows a step drop, the smart module will send a stop command to the driving device to stop the operation of the driving device.

Staple cartridge assembly and medical stapler using the staple cartridge assembly

A staple cartridge assembly comprises a connector, a cutter push rod and an elastic sheet, the elastic sheet having a first through groove and the cutter push rod being formed by laminating multiple sheets, wherein when the staple cartridge assembly is in an original status or a closed status, part of the cutter push rod is located in the first through groove, and the first through groove restricts detaching of the multiple sheets in a laminating direction of the multiple sheets; in a firing process of the staple cartridge assembly, the cutter push rod moves towards a distal end of the staple cartridge assembly to press the elastic sheet, such that the elastic sheet deforms and the cutter push rod is gradually detached from the first through groove; after the firing of the staple cartridge assembly is finished, the cutter push rod is detached from the first through groove.

Substrate distance monitoring

Embodiments disclosed herein include a faceplate having a sensor assembly, a processing chamber having the same, and a method for monitoring a substrate in a processing chamber. In one embodiment, a faceplate is configured to introduce processing gases into a plasma processing chamber. The faceplate has one or more holes. A sensor assembly is disposed in the one or more holes. The sensor assembly has a sensor and a controller.

Inverting thrombectomy apparatuses and methods

Rolling tractor tube mechanical thrombectomy apparatuses that may be deployed from out of a catheter in situ are described herein. These apparatuses may be delivered out of a catheter from a collapsed delivery configuration within the catheter to a deployed configuration out of the catheter, in which the same catheter is re-inserted between a tubular tractor and an elongate puller. In particular, any of these methods and apparatuses may be adapted to work with a tractor tube having an open end that is biased open, including using an annular bias.

Reinforced balloon catheter

A balloon catheter is described having a reinforced, co-axial, duel lumen design. In some embodiments, the balloon catheter includes a purging mechanism designed to purge air from the balloon.

Cryptographic applications for a blockchain system

A method is provided for delegating behavior of a smart contract associated with a blockchain to code that is not part of the blockchain. A system directs execution by a virtual machine of the smart contract. During execution of the smart contract, the smart contract sends to a cryptlet container service, via a cryptodelegate, a request to delegate a behavior to a cryptlet that executes on an attested host. During execution the cryptlet container service identifies a host for executing code of the cryptlet in an appropriate cryptlet container. The cryptlet container service directs the identified host to execute the code of the cryptlet to perform the delegated behavior. After the delegated behavior is performed, the cryptlet container service receives from the cryptlet a response to the requested behavior. The cryptlet container service sends the response to the smart contract on the blockchain that is verified by the cryptodelegate.

Method and device for motion control of a mobile medical device

Collision-free movement of a mobile medical device, such as a mobile medical imaging device, in a room is controlled via a man-machine interface. A model of the room environment is created and displayed, together an actual position of the medical device. The room model and the actual position are based at least in part on real-time sensor data. A destination position for the medical device is entered, the entered destination position is displayed and a collision-free movement path is generated from the actual position to the destination position. The movement path is displayed in the room model. A movement command relating to the displayed movement path is entered and the medical device is driven along the entered movement path from the actual position to the destination position.

Privacy preserving distributed evaluation framework for embedded personalized systems

Systems and processes for evaluating embedded personalized systems are provided. In one example process, instructions that define an experiment associated with a personalized speech recognition system can be received. The instructions can define one or more experimental parameters. In accordance with the received instructions, a second personalized speech recognition system can be generated based on the personalized speech recognition system and the one or more experimental parameters. Additionally, the plurality of user speech samples can be processed using the second personalized speech recognition system to generate a plurality of speech recognition results and a plurality of accuracy scores corresponding to the plurality of speech recognition results. Second instructions can be received based on the plurality of accuracy scores. In accordance with the second instructions, the second speech recognition system can be activated.

Intelligent list reading

Systems and processes for operating an intelligent automated assistant to perform intelligent list reading are provided. In one example process, a spoken user request associated with a plurality of data items is received. The process determines whether a degree of specificity of the spoken user request is less than a threshold level. In response to determining that a degree of specificity of the spoken user request is less than a threshold level, one or more attributes related to the spoken user request are determined. The one or more attributes are not defined in the spoken user request. Additionally, a list of data items based on the spoken user request and the one or more attributes is obtained. A spoken response comprising a subset of the list of data items is generated and the spoken response is provided.
