Hand held surgical device for manipulating an internal magnet assembly within a patient

摘要

A device for manipulating a magnetic coupling force across tissue in response to a monitored coupling force is described. The device includes a magnetic field source assembly, a positioning assembly operatively connected to the magnetic field force assembly, and a magnetic coupling force monitor. The magnetic field source assembly includes magnets that provide an external magnetic field source for providing a magnetic field across tissue. The positioning assembly adjusts the position of the magnetic field source. The magnetic field creates a magnetic coupling force between the external magnetic field source and an object positioned in use in a patient during a procedure, wherein the object has or is associated with an internal magnetic field.

1. A device for manipulating a magnetic coupling force across tissue comprising:
a magnetic field source assembly comprising a first magnetic field source for providing, in use, a magnetic field across tissue, the first magnetic field source providing a magnetic coupling force between the first magnetic field source and an object providing a second magnetic field source; a positioning assembly operatively connected to the magnetic field source assembly for adjusting an elevational position of the first magnetic field source, the positioning assembly having a driver for adjusting the elevational position of the magnetic field source assembly and an actuator for moving the driver; a magnetic coupling force monitor; and an outer housing containing at least the magnetic field source assembly, the outer housing configured to allow elevational adjustment of the magnetic field source assembly within the housing;wherein the magnetic field source assembly further comprises:
a magnet housing, a magnet support, and the first magnetic field source comprises at least one magnet, the at least one magnet being held by the magnet support and suspended within the magnet housing.
