TLDR
In this paper, a first magnetic field can be produced across a tissue region using a first magnetometer, providing a magnetic coupling force between the first magnetic source and a first object, wherein the first object provides a magnetic field or a magnetic susceptibility to obtain the magnetic coupling forces.Abstract:
A first magnetic field can be produced across a tissue region using a first magnetic field source, providing a magnetic coupling force between the first magnetic field source and a first object, wherein the first object provides a magnetic field or a magnetic susceptibility to obtain the magnetic coupling force. The magnetic coupling force can be sensed using a force sensor and a resulting sensed force signal can be provided to a controller. The controller can provide an output signal to control the magnetic coupling force using the sensed forced signal to obtain a constant or desired magnetic coupling force.read more

Interactive surgical systems with condition handling of devices and data capabilities
TL;DR: In this paper, a surgical hub is configured to authenticate data communications with surgical devices, where a processor and a memory storing instructions executable by the processor can transmit a public key to a detected surgical device, receive a message from the surgical device encrypted using the public key associated with the surgical hub, the encrypted message comprising a shared secret associated with a surgical device and a checksum value, derived via the checksum function, based on the data communications; and decrypt the encrypted messages using the shared secret.
Patent
Communication hub and storage device for storing parameters and status of a surgical device to be shared with cloud based analytics systems
TL;DR: In this paper, the authors describe a surgical hub consisting of a storage device, a processor coupled to the storage device and a memory coupled to a processor, where the memory stores instructions executable by the processor to receive data from a surgical instrument and determine a rate at which to transfer the data from the surgical hub to a remote cloud-based medical analytics network based on available storage capacity.
