Depicting force

1. A non-transitory computer readable medium storing instructions for depicting a force exerted on a distal end of an elongate medical device, the instructions executable by a processing resource to cause a computer to:

determine the force exerted on the distal end of the elongate medical device;

compute a graphical representation of the distal end of the elongate medical device and a graphical representation of the force exerted on the distal end of the elongate medical device, wherein the graphical representation of the force emanates from the graphical representation of the distal end of the elongate medical device, wherein the force is determined from a signal received from a force sensor included in the elongate medical device;

increase a first dimension of the graphical representation of the force in response to a longitudinal force being exerted on the distal end of the elongate medical device; and

increase a second dimension of the graphical representation of the force in response to a lateral force being exerted on the distal end of the elongate medical device, wherein the first dimension is different than the second dimension, and wherein:

the first dimension relates to a longitudinal length of the graphical representation of the force;

the first dimension of longitudinal length is altered based on a change in magnitude of a longitudinal force being exerted on the distal end of the elongate medical device;

the second dimension relates to a lateral width of the graphical representation of the force; and

the second dimension of lateral width is altered based on a change in lateral force being exerted on the distal end of the elongate medical device; and

cause the graphical representation of the distal end of the elongate medical device and a graphical representation of the force exerted on the distal end of the elongate medical device to be displayed to a user.

2. The non-transitory computer readable medium of claim 1 , wherein the instructions executable by the processing resource to determine the force exerted on the distal end of the elongate medical device include instructions executable to determine an amount of longitudinal force exerted on the distal end of the elongate medical device and an amount of lateral force exerted on the distal end of the elongate medical device.

3. The non-transitory computer readable medium of claim 1 , wherein the instructions executable to display the graphical representation of the force exerted on the distal end of the elongate medical device include instructions executable to display an indicator shape that is representative of the force exerted on the distal end of the elongate medical device.

4. The non-transitory computer readable medium of claim 3 , further comprising executable instructions to:

increase a first dimension of the indicator shape in response to a change in the amount of longitudinal force being exerted on the distal end of the elongate medical device; and

increase a second dimension of the indicator shape in response to a change in the amount of lateral force being exerted on the distal end of the elongate medical device.

5. The non-transitory computer readable medium of claim 1 , wherein the instructions are executable to display the graphical representation of the longitudinal force as a cylinder that extends from a distal end of the graphical representation of the elongate medical device and along a longitudinal axis defined by the elongate medical device.

6. The non-transitory computer readable medium of claim 5 , wherein the instructions are executable to display the graphical representation of the amount of longitudinal force as the cylinder, in response to the amount of longitudinal force exceeding a defined amount of longitudinal force and an amount of lateral force being less than a defined amount of lateral force.

7. The non-transitory computer readable medium of claim 5 , wherein the instructions are executable to change a longitudinal length of the cylinder in response to a change in the longitudinal force exerted on the distal end of the elongate medical device.

8. The non-transitory computer readable medium of claim 1 , wherein the instructions are executable to display the graphical representation of the lateral force as a disk that emanates from the graphical representation of the distal end of the elongate medical device.

9. The non-transitory computer readable medium of claim 8 , wherein the instructions are executable to display the graphical representation of the amount of lateral force as the disk, in response to the amount of the lateral force exceeding a defined amount of lateral force and an amount of longitudinal force being less than a defined amount of longitudinal force.

10. The non-transitory computer readable medium of claim 1 , wherein the instructions are executable to change a color of the indicator shape from a first color to a second color in response to an amount of the force exerted on the distal end of the elongate medical device exceeding a threshold.

11. The non-transitory computer readable medium of claim 1 , wherein a diameter of the graphical representation of force decreases to zero in the absence of the lateral force.

12. The non-transitory computer readable medium of claim 1 , wherein a length of the graphical representation of force decreases to zero in the absence of the longitudinal force.
