Abstract
A medical device includes a disposable Ear-Nose-Throat (ENT) tool, a reusable handle, and a processor. The ENT tool is configured to perform a medical procedure in a patient ENT organ. The reusable handle is configured to hold and control the disposable ENT tool, and includes a position sensor configured to produce one or more position signals that are indicative of a first position of the reusable handle. The processor is configured to receive the position signals from the position sensor, and to estimate, based on the position signals, a second position of the disposable ENT tool in the patient ENT organ.
Claims17
A medical device, comprising:
- (a) a disposable Ear-Nose-Throat tool, which is configured to perform a medical procedure in a patient Ear-Nose-Throat location, wherein the disposable Ear-Nose-Throat tool comprises:
- (i) a distal tip,
- (ii) a proximal end, and
- (ii) a remotely readable memory comprising a first offset vector indicative of a displacement between the distal tip and the proximal end;
- (b) a reusable handle, which is configured to hold and control the disposable Ear-Nose-Throat tool at the proximal end via a mechanical connector, wherein the reusable handle comprises a position sensor configured to produce one or more position signals that are indicative of a first position of the sensor;
- and
- (c) a processor storing a second offset vector indicative of a displacement between the mechanical connector and the sensor, wherein the processor is configured to read the remotely readable memory of the disposable Ear-Nose-Throat tool to obtain the first offset vector, wherein the processor is configured to receive the position signals from the position sensor, and to estimate, based on a combination of the first offset vector, the second offset vector, and the one or more position signals, a position of the distal tip in the patient Ear-Nose-Throat location.
A method, comprising:
- (a) receiving a data from a remotely readable memory attached to a disposable Ear-Nose-Throat tool that applies a medical procedure in a patient Ear-Nose-Throat location, wherein the data comprises a first offset vector indicative of a displacement between a distal tip and a proximal end of the disposable Ear-Nose-Throat tool,
- (d) receiving from a position sensor, which is coupled to a reusable handle that is external to the patient Ear-Nose-Throat location and holds and controls the Ear-Nose-Throat tool, one or more position signals that are indicative of a first position of the reusable handle;
- (c) estimating, based on a first position signal, the first offset vector, and a second offset vector indicative of a displacement between the position sensor and a mechanical coupling between the disposable Ear-Nose-Throat tool and the reusable handle, a position of distal tip of the disposable Ear-Nose-Throat tool in the patient Ear-Nose-Throat location;
- (d) navigating the disposable Ear-Nose-Throat tool to a target location in the patient Ear-Nose-Throat location by setting a second position at the target location.
A medical device, comprising:
- (a) a disposable Ear-Nose-Throat tool, which is configured to perform a medical procedure in a patient, wherein the disposable Ear-Nose-Throat tool comprises:
- (i) a distal tip,
- (ii) a readable memory, wherein the readable memory comprises a data comprising a first offset vector indicative of a position of the distal tip, and
- (b) a reusable handle, which is configured to hold and control the disposable Ear-Nose-Throat tool, wherein the reusable handle comprises a position sensor configured to produce one or more position signals that are indicative of a first position of the sensor;
- and
- (c) a processor storing a second offset vector indicative of a position of the sensor relative to a mechanical coupling between the reusable handle and the disposable Ear-Nose-Throat tool, wherein the processor is configured to receive the position signals from the position sensor, and to estimate a position of the distal tip in the patient, based on the position signals, the first offset vector, and the second offset vector.
