Abstract

In some examples, a device includes a body configured to receive an elongated medical device, and a conductive element configured to contact a touchscreen of a computing device. An amount of contact between the conductive element and the touchscreen varies based on the compressive force applied to the elongated medical device when the elongated medical device is received within the body.

First claim

What is claimed is:

1. A device comprising:
a body configured to receive an elongated medical device, wherein the elongated medical device is configured to be introduced into a patient; and
a conductive element configured to contact a touchscreen of a computing device, wherein an amount of contact between the conductive element and the touchscreen varies based on a compressive force applied to the elongated medical device when the elongated medical device is received within the body, wherein the body is configured to support and align the elongated medical device with respect to the conductive element; and
wherein the conductive element is pivotably connected to the body via a hinge.

2. The device of claim 1 , wherein the body comprises:
a first body portion defining a first opening; and
a second body portion defining a second opening aligned with the first opening, wherein the first opening and the second opening are configured to receive the medical device.

3. The device of claim 2 , wherein the first and second body portions are spaced apart from one another such that, in response to the compressive force, the medical device bends in a region between the first and second body portions.

4. The device of claim 1 , wherein the conductive element comprises conductive silicone rubber.

5. The device of claim 1 , wherein the amount of contact comprises at least one of a surface area between the touchscreen and the conductive element or an amount of force applied to the touchscreen by the conductive element.

6. A system comprising:
the device of claim 1 ; and
the computing device.

7. The system of claim 6 , wherein the computing device comprises processing circuitry configured to:
receive input via the touchscreen, wherein the input indicates the amount of contact between the conductive element and the touchscreen,
determine a parameter based on the input, and
generate a graphical user interface indicating the determined parameter.

8. The system of claim 7 , wherein the parameter comprises a magnitude of the compressive force applied to the conductive element via the elongated medical device when the elongated medical device is received within the body.

9. The system of claim 7 , wherein the processing circuitry is configured to determine a minimum compressive force that causes the elongated medical device to bend based on an electrical signal generated by the touchscreen based on the amount of contact between the conductive element and the touchscreen.

10. The device of claim 1 , wherein when the body receives the elongated medical device and before the compressive force is applied to the elongated medical device, the body is configured to hold a longitudinal axis of the elongated medical device substantially parallel or substantially perpendicular to a major surface of the touch screen.

11. A device comprising:
a body configured to receive an elongated medical device, wherein the elongated medical device is configured to be introduced into a patient; and
a conductive element configured to contact a touchscreen of a computing device, wherein an amount of contact between the conductive element and the touchscreen varies based on a compressive force applied to the elongated medical device when the elongated medical device is received within the body,
wherein the body comprises:
a first body portion defining a first through opening; and
a second body portion defining a second through opening, wherein the first through opening and the second through opening are aligned and configured to receive the medical device, and wherein a first part of the first body portion defining the first through opening is spaced from a second part of the second body portion defining the second through opening;
wherein the conductive element is pivotably connected to the body via a hinge.

12. The device of claim 11 , wherein the first body portion comprises a first arm, the second body portion comprises a second arm, and the body further comprises a base between the first arm and the second arm.

13. The device of claim 11 , wherein when the body receives the elongated medical device and before the compressive force is applied to the elongated medical device, the body is configured to hold a longitudinal axis of the elongated medical device substantially parallel or substantially perpendicular to a major surface of the touch screen.

14. The device of claim 11 , wherein the body is configured to receive the medical device such that a distal end of the medical device engages a lever connected to the conductive element.
