Controllable magnetic source to fixture intracorporeal apparatus

Peter K. Allen, +1 more
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.

Controlling a surgical instrument according to sensed closure parameters

Frederick E. Shelton, +4 more
TL;DR: In this article, a control circuit is configured to determine a value of the tissue compression parameter via the sensor as the jaws transition from the open configuration to the closed configuration, which causes the motor to increase a time to transition the jaws to a closed configuration according to whether the value of tissue compression parameters is above a first threshold, and provide feedback when the value is below a second threshold.
