Abstract

A surgical instrument comprises an articulable end effector; a drive shaft connected to the end effector that drives the end effector; an electric motor connected to the drive shaft that drives the drive shaft; a battery unit for supplying power to the electric motor; at least one sensor for sensing a status of the instrument; and an alphanumeric display located on the instrument and in communication with the at least one sensor. The alphanumeric display is for displaying alphanumeric characters that display visually to a user of the instrument a status of the instrument based on an input from the at least one sensor.

Claims (26)

1. A surgical instrument comprising:

an articulable end effector that comprises:

first and second opposing jaw member for clamping tissue therebetween;

a cutting instrument that is for, when fired, cutting tissue clamped in the end effector, wherein, when fired, the cutting instrument moves from a first position in the end effector to a second position in the end effector to cut the tissue clamped in the end effector; and

a removable cartridge;

a drive shaft connected to the end effector that drives the cutting instrument;

an electric motor connected to the drive shaft that drives the drive shaft;

a battery unit for supplying power to the electric motor;

at least one sensor for sensing a status of the instrument;

a handle housing at least a portion of the battery; and

an alphanumeric display on the handle and in communication with the at least one sensor, wherein the alphanumeric display is for displaying alphanumeric characters that display visually to a user of the instrument a status of the instrument based on an input from the at least one sensor, wherein the alphanumeric display visually displays at least the following status to the user:

whether the removable cartridge is loaded; and

an articulation angle of the end effector.

2. The surgical instrument of claim 1 , wherein the alphanumeric display indicates whether the removable cartridge is positioned in the end effector.

3. The surgical instrument of claim 1 , wherein:

the cutting instrument in the end effector, when fired, moves from a first position in the end effector to a second position in the end effector to the cut tissue clamped in the end effector;

the at least one sensor comprises at least one position sensor for sensing a position of the cutting instrument in the end effector; and

the alphanumeric display indicates a position of the cutting instrument in the end effector.

4. The surgical instrument of claim 1 , wherein the alphanumeric display is removably connected to the handle.

5. The surgical instrument of claim 1 , wherein the alphanumeric display further visually displays to the user a time elapsed since tissue was clamped in the end effector.

6. The surgical instrument of claim 1 , wherein the alphanumeric display further visually provides information related to a clamping force exerted by the end effector.

7. The surgical instrument of claim 1 , wherein the alphanumeric display further visually displays a status of a cutting force exerted by the cutting instrument.

8. The surgical instrument of claim 7 , wherein the alphanumeric display indicates whether the cutting force is within an expected range or whether the cutting force is outside the expected range.

9. The surgical instrument of claim 7 , wherein the alphanumeric display indicates a percentage of a maximum firing force exerted by the cutting instrument.

10. The surgical instrument of claim 1 , wherein the alphanumeric display further visually displays a position of the cutting instrument in the end effector.

11. The surgical instrument of claim 1 , wherein the at least one sensor comprises an articulation angle sensor that senses an articulation angle of the end effector.
