Abstract

A surgical system and a computing device for a surgical system that is configured to calculate actual operating parameters of an electrosurgical instrument, including an actual angle between the jaw members of the electrosurgical instrument, and to display a user interface. The user interface includes an ideal angle range between the jaw members and the actual angle between the jaw members of the electrosurgical instrument relative to the ideal angle range. The computing device is further configured to determine if the actual angle between the jaw members of the electrosurgical instrument is outside the ideal angle range.

First claim

What is claimed is:

1. A surgical system, comprising:
an electrosurgical generator configured to generate electrosurgical energy;
an electrosurgical instrument configured to operably couple to the electrosurgical generator, the electrosurgical instrument including:
a housing;
an elongated member extending distally from the housing; and
an end effector assembly operably coupled to a distal portion of the elongated member, the end effector assembly including a pair of opposing jaw members, at least one of the jaw members moveable relative to the other to grasp tissue therebetween, at least one of the jaw members adapted to connect to the electrosurgical generator for conducting electrosurgical energy through grasped tissue; and

a computing device operably coupled to the electrosurgical instrument, the computing device configured to:
calculate an actual angle between the jaw members of the electrosurgical instrument; and
display a user interface including:
a representation of the jaw members of the end effector assembly defining an angle therebetween;
an ideal angle range between the jaw members, the ideal angle range displayed as a first portion of the angle defined between the jaw members of the representation, the first portion marked;
the actual angle between the jaw members, the actual angle displayed relative to the ideal angle range as a second portion of the angle defined between the jaw members of the representation; and
a difference between the actual angle and the ideal angle displayed as a third portion of the angle defined between the jaw members, there being a demarcation between the third portion and the second portion.

2. The surgical system of claim 1 , wherein the computing device is further configured to determine if the actual angle between the jaw members of the electrosurgical instrument is outside the ideal angle range.

3. The surgical system of claim 2 , wherein the computing device is further configured to generate at least one of an audible, visible, or tactile alert when it is determined that the actual angle between the jaw members of the electrosurgical instrument is outside the ideal angle range.

4. The surgical system of claim 2 , wherein the computing device is further configured to control an output of the electrosurgical generator when it is determined that the actual angle between the jaw members of the electrosurgical instrument is outside the ideal angle range.

5. The surgical system of claim 2 , wherein:
the actual angle between the jaw members is displayed in a first color when the actual angle between the jaw members of the electrosurgical instrument is within the ideal angle range; and
the actual angle between the jaw members is displayed in a second color, different from the first color, when the actual angle between the jaw members of the electrosurgical instrument is outside the ideal angle range.

6. The surgical system of claim 1 , wherein the electrosurgical instrument includes an angle sensor operably coupled to the end effector assembly and configured to sense the actual angle between the jaw members.

7. The surgical system of claim 1 , wherein the electrosurgical instrument includes a force sensor operably coupled to the end effector assembly and configured to sense an actual external force against the end effector assembly.

8. The surgical system of claim 1 , wherein the user interface includes:
an ideal external force range against the end effector assembly; and
an actual external force against the end effector assembly relative to the ideal external force range.

9. The surgical system of claim 8 , wherein the user interface includes an arrow representing a direction of the actual external force against the end effector assembly.

10. The surgical system of claim 1 , wherein the electrosurgical instrument includes a torque sensor operably coupled to the elongated member and configured to sense an actual external torsional force against the elongated member.

11. The surgical system of claim 1 , wherein the user interface includes:
an ideal external torsional force range against the elongated member; and
an actual external torsional force against the elongated member relative to the ideal external torsional force range.

12. An electrosurgical generator including a processor and a memory storing instructions which, when executed by the processor, cause the processor to:
calculate actual operating parameters of an electrosurgical instrument including an external force applied against at least one of an end effector assembly of the electrosurgical instrument or an elongated member of the electrosurgical instrument that supports the end effector assembly;
determine if an actual external force applied against the at least one of the jaw members or the elongated member is outside an ideal external force range; and
display a user interface including:
a graphical representation of the ideal external force range;
a graphical representation of the actual external force relative to the ideal external force range, wherein:
the actual external force is displayed in a first color when the actual external force is within the ideal external force range; and
the actual external force is displayed in a second color, different from the first color, when the actual external force is outside the ideal external force range; and

a graphical representation of a difference between the actual external force and the ideal external force range.

13. The electrosurgical generator of claim 12 , wherein the instructions, when executed by the processor, cause the processor to control an output of the electrosurgical generator when it is determined that the actual external force is outside the ideal external force range.

14. The electrosurgical generator of claim 12 , wherein the actual operating parameters include the actual external force applied against the end effector assembly and the user interface includes:
the ideal external force range against the end effector assembly; and
the actual external force against the end effector assembly relative to the ideal external force range.

15. The electrosurgical generator of claim 12 , wherein the actual operating parameters include the actual external force applied against the elongated member and the user interface includes:
the ideal external force range against the elongated member; and
the actual external force range against the elongated member relative to the ideal external force range.

16. The electrosurgical generator of claim 15 , wherein the actual external force applied against the elongated member is an actual torsional force against the elongated member.

17. A user interface for an electrosurgical system, the user interface comprising:
a graphical representation of an ideal angle range between two jaw members of an end effector assembly of an electrosurgical instrument;
a graphical representation of an actual angle between the jaw members of the electrosurgical instrument relative to the ideal angle range, wherein:
the actual angle between the jaw members is displayed in a first color when the actual angle between the jaw members of the electrosurgical instrument is within the ideal angle range;
the actual angle between the jaw members is displayed in a second color, different from the first color, when the actual angle between the jaw members of the electrosurgical instrument is outside the ideal angle range; and

a graphical representation of a difference between the actual angle and the ideal angle when the actual angle between the jaw members of the ele
