Surgical system and method of evaluating the extent to which a limb is held by a limb holder
Surgical systems and methods to interact with a limb of a patient held by a limb holder. An instrument is configured to apply a force externally to the limb held by the limb holder, One or more controllers measure an extent to which the limb moves relative to the limb holder in response to the force applied externally to the limb by the instrument. The one or more controllers generate, based on the measured extent, a notification relating to physical adjustment of one or both of the limb and the limb holder.
1. A surgical system configured to interact with a limb of a patient held by a limb holder, the surgical system comprising:
an instrument configured to apply a force externally to the limb held by the limb holder; and
one or more controllers configured to:
measure an extent to which the limb moves relative to the limb holder in response to the force applied externally to the limb by the instrument; and
generate, based on the measured extent, a notification relating to physical adjustment of the limb, wherein the notification suggests repositioning the limb from a current position to a suggested position;
monitor movement of the limb and determine whether the limb has reached the suggested position; and
generate a second notification for communicating that the limb has reached the suggested position.
2. The surgical system of claim 1 , further comprising a display device, and wherein the one or more controllers are further configured to concurrently display the current position of the limb relative to the suggested position of the limb.
3. The surgical system of claim 1 , wherein the one or more controllers are configured to:
generate the notification to further suggest repositioning the limb holder from a current position to a suggested position;
monitor movement of the limb holder and determine whether the limb holder has reached the suggested position; and
generate a second notification for communicating that the limb holder has reached the suggested position.
4. The surgical system of claim 3 , further comprising a display device, and wherein the one or more controllers are further configured to concurrently display the current position of the limb holder relative to the suggested position of the limb holder.
5. The surgical system of claim 1 , wherein the one or more controllers are configured to generate the notification to further suggest tightening a retaining feature of the limb holder.
6. The surgical system of claim 1 , further comprising a display device, and wherein the one or more controllers are further configured to generate the notification on the display device as an image, text and/or an animation.
7. The surgical system of claim 1 , wherein the one or more controllers are configured to measure the extent by comparing an actual position of the instrument relative to the limb with an intended position of the instrument relative to the limb.
8. The surgical system of claim 1 , wherein the one or more controllers are configured to measure the extent by measuring one or more of:
a displacement of the limb and/or limb holder; and
a stiffness of the limb and/or limb holder.
9. The surgical system of claim 1 , wherein the one or more controllers are configured to measure the extent by measuring a response of the limb accounting for one or more of:
a mass of the limb; and/or
a mass of the limb holder.
10. The surgical system of claim 1 , further comprising a navigation system configured to track a position of the limb and/or limb holder and wherein the one or more controllers are configured to measure the extent by evaluating the tracked position of the limb and/or limb holder.
11. A method of operating a surgical system configured to interact with a limb of a patient held by a limb holder, the surgical system comprising an instrument configured to apply a force externally to the limb held by the limb holder, and one or more controllers, the method comprising:
measuring, with the one or more controllers, an extent to which the limb moves relative to the limb holder in response to the force applied externally to the limb by the instrument; and
generating, based on the measured extent, and with the one or more controllers, a notification relating to physical adjustment of the limb; wherein the notification suggests repositioning the limb from a current position to a suggested position;
monitoring movement of the limb for determining whether the limb has reached the suggested position; and
generating a second notification for communicating that the limb has reached the suggested position.
12. The method of claim 11 , comprising the one or more controllers:
generating the notification to further suggest repositioning the limb holder from a current position to a suggested position;
monitoring movement of the limb holder for determining whether the limb holder has reached the suggested position; and
generating a second notification for communicating that the limb holder has reached the suggested position.
13. The method of claim 11 , comprising the one or more controllers generating the notification to further suggest tightening a retaining feature of the limb holder.
14. The method of claim 11 , comprising the one or more controllers measuring the extent by comparing an actual position of the instrument relative to the limb with an intended position of the instrument relative to the limb.
15. The method of claim 11 , comprising the one or more controllers measuring the extent by measuring one or more of:
a displacement of the limb and/or limb holder; and
a stiffness of the limb and/or limb holder.
16. The method of claim 11 , comprising the one or more controllers measuring the extent by measuring a response of the limb accounting for one or more of:
a mass of the limb; and/or
a mass of the limb holder.
17. The method of claim 11 , further comprising:
tracking, with a navigation system, a position of the limb and/or limb holder; and
measuring, with the one or more controllers, the extent by evaluating the tracked position of the limb and/or limb holder.
18. A surgical system configured to interact with a limb of a patient held by a limb holder, the surgical system comprising:
an instrument configured to apply a force externally to the limb held by the limb holder; and
one or more controllers configured to:
measure an extent to which the limb moves relative to the limb holder in response to the force applied externally to the limb by the instrument; and
generate, based on the measured extent, a notification relating to physical adjustment of the limb holder, wherein the notification suggests repositioning the limb holder from a current position to a suggested position;
monitor movement of the limb holder and determine whether the limb holder has reached the suggested position; and
generate a second notification for communicating that the limb holder has reached the suggested position.
19. A method of operating a surgical system configured to interact with a limb of a patient held by a limb holder, the surgical system comprising an instrument configured to apply a force externally to the limb held by the limb holder, and one or more controllers, the method comprising:
measuring, with the one or more controllers, an extent to which the limb moves relative to the limb holder in response to the force applied externally to the limb by the instrument; and
generating, based on the measured extent, and with the one or more controllers, a notification relating to physical adjustment of the limb holder, wherein the notification suggests repositioning the limb holder from a current position to a suggested position;
monitoring movement of the limb holder for determining whether the limb holder has reached the suggested position; and
generating a second notification for communicating that the limb holder has reached the suggested position.
