Method of compressing tissue within a stapling device and simultaneously displaying the location of the tissue within the jaws
A method of compressing tissue during a surgical procedure is disclosed. The method comprises obtaining a surgical instrument comprising an end effector, wherein the end effector comprises a first jaw and a second jaw, establishing a communication pathway between the surgical instrument and a surgical hub, and inserting the surgical instrument into a surgical site. The method further comprises compressing tissue between the first jaw and the second jaw, determining a location of the compressed tissue with respect to at least one of the first jaw and the second jaw, communicating the determined location of the compressed tissue to the surgical hub, and displaying the determined location of the compressed tissue on a visual feedback device.
1. A method, comprising:
inserting a surgical instrument comprising an end effector into a surgical site positioned within a sterile field, wherein the end effector comprises a first jaw and a second jaw, wherein the first jaw and the second jaw are configurable between an open configuration and a closed configuration;
transitioning the end effector toward a partially closed configuration intermediate the open configuration and the closed configuration to contact tissue positioned between the first jaw and the second jaw;
determining an area of the end effector in contact with the tissue at the partially closed configuration;
setting a closure rate of the end effector based on the determined area and a position of the second jaw relative to the first jaw;
communicating the determined area to a surgical hub, wherein the surgical hub is positioned outside the sterile field; and
displaying the determined area on a display of the surgical hub.
2. The method of claim 1 , wherein the area is determined using a series of impedance sensors.
3. The method of claim 2 , wherein each impedance sensor is configured to determine if tissue is positioned thereagainst to determine the area.
4. The method of claim 1 , wherein the area is determined using a series of photoacoustic sensors.
5. The method of claim 1 , wherein the area is determined using a thin film coating.
6. A method of grasping tissue during a surgical procedure, wherein the method comprises:
grasping tissue between a first jaw and a second jaw of an end effector of a surgical instrument;
determining a degree of contact between the grasped tissue and the end effector; and
setting a closure rate of the end effector based on the determined degree of contact and a position of the second jaw relative to the first jaw.
7. The method of claim 6 , wherein the degree of contact is determined using a plurality of impedance sensors.
8. The method of claim 7 , wherein the impedance sensors are configured to determine if tissue is positioned thereagainst to determine the degree of contact.
9. The method of claim 6 , wherein the degree of contact is determined using a plurality of photoacoustic sensors.
10. The method of claim 6 , wherein the degree of contact is determined using a thin film coating.
11. A method, comprising:
establishing a wireless communication pathway between a surgical instrument and a surgical hub, wherein the surgical hub comprises a visual feedback device, and wherein the surgical instrument comprises an end effector comprising a first jaw and a second jaw movable relative to the first jaw between an open position and a closed position;
inserting the surgical instrument into a surgical site;
moving the second jaw toward a first position intermediate the open position and the closed position to contact tissue positioned between the first jaw and the second jaw;
determining a degree of contact between the tissue and the end effector at the first position;
setting a closure rate of the end effector based on the determined degree of contact;
communicating the determined degree of contact to the surgical hub; and
displaying the determined degree of contact on the visual feedback device;
further comprising determining an angle between the first jaw and the second jaw at the first position, wherein setting the closure rate of the end effector is further based on the determined angle between the first jaw and the second jaw.
12. The method of claim 11 , wherein the degree of contact is determined using a series of impedance sensors.
13. The method of claim 12 , wherein the impedance sensors are positioned along the first jaw of the surgical instrument.
14. The method of claim 12 , wherein each impedance sensor is configured to determine if tissue is positioned thereagainst to determine the degree of contact.
15. The method of claim 12 , wherein the impedance sensors are positioned along the second jaw of the surgical instrument.
16. The method of claim 11 , wherein the degree of contact is determined using a series of photoacoustic sensors.
17. The method of claim 11 , wherein the degree of contact is determined using a thin film coating.
18. The method of claim 11 , further comprising moving the second jaw toward the closed position at the closure rate.
19. The method of claim 11 , wherein the first position comprises a position at which the end effector makes initial contact with the tissue.
