Abstract
Provided herein are systems, devices, assemblies, and methods for localization of a tag in a tissue of a patient. For example, provided herein are systems, devices, and methods employing a detection component that is attached to or integrated with a surgical device, where the detection component detects a signal from a tag in a patient, where the tag is activated by remote introduction of a magnetic field.
Claims7
A method for localizing a tissue region of a patient, comprising:
- a) placing a remote activating device and a patient in proximity to each other,
- wherein said remote activating device generates a magnetic field, and
- wherein said patient comprises a tag at a location in, on, or proximal to a tissue of said patient;
- and
- b) localizing said tag in said patient by generating a magnetic field with said remote activating device and detecting a signal from said tag using a detector component,
- wherein said detector component comprises an electronics component and at least one sense coil and is attached to, or integrated with, a surgical device, wherein said electronics component comprises a signal processor, and
- wherein said detector component and said remote activating device are separate.
4 more elements
A system comprising:
- i) a surgical instrument comprising a cutting and/or cautery tip,
- ii) a remote activating device that generates a magnetic field, wherein said remote activating device comprises a flat pad configured to be positioned under a patient, wherein said flat pad comprises multiple activating coils, wherein each of said activating coils comprises magnet wire wound around a mandrel,
- iii) an RFID tag that is insertable at a location in or on a tissue of said patient wherein said RFID tag is activated by said magnetic field,
- iv) a control unit comprising a processor and a control software, wherein said control unit is linked to said remote activating device, and,
- v) a visual display component configured to display a distance of said cutting or cautery tip to said RFID tag.
