Accessing data stored in a memory of a surgical instrument
View Patent ↗A process and system are disclosed for downloading sensor data, stored in a memory device of a surgical cutting and fastening instrument, to an external or remote computer device. The process may involve storing data from one or more sensors of a surgical cutting and fastening instrument in a memory device of a control unit of the surgical cutting and fastening instrument during a surgical procedure involving the surgical cutting and fastening instrument. Next, after the surgical procedure, a data link between the control unit and the remote computer device is established. Then, the sensor data can be downloaded from the control unit to the remote computer device.
1. A system for capturing sensor data from a surgical procedure, the system comprising:
a surgical cutting and fastening instrument, wherein the surgical cutting and fastening instrument comprises:
a control unit comprising a memory device;
a shaft;
an end effector connected to the shaft, wherein the end effector comprises:
first and second opposing jaw members for clamping tissue therebetween; and
a cutting instrument that traverses longitudinally the end effector when actuated; and
at least one sensor in communication with the control unit, wherein the memory device stores data from the at least one sensor, and wherein the at least one sensor comprises a cutting instrument position sensor, located in the end effector, that senses a position of the cutting instrument in the end effector; and
an external computer device in communication with the control unit of the surgical cutting and fastening instrument via a data link, wherein the external computer device is for downloading data from the memory device of the control unit of the surgical cutting and fastening instrument.
2. The system of claim 1 , wherein the data link comprises a wired data link.
3. The system of claim 1 , wherein the data link comprises a wireless data link.
4. The system of claim 1 , wherein the surgical cutting and fastening instrument further comprises a handle comprising a firing trigger.
5. The system of claim 4 , wherein the handle further comprises a closure trigger, separate from the firing trigger, for causing the first and second jaw members to clamp tissue between the first and second jaw members when the closure trigger is actuated.
6. The system of claim 5 , wherein:
the at least one sensor comprises an anvil closure sensor in communication with the control unit, wherein the anvil closure sensor senses closure of the second jaw member; and
the memory device of the control unit stores data from the anvil closure sensor.
7. The system of claim 5 , wherein:
the at least one sensor comprises a anvil closure trigger, sensor in communication with the control unit, wherein the closure trigger sensor senses actuation of the closure trigger; and
the memory device of the control unit stores data from the closure trigger sensor.
8. The system of claim 5 , wherein:
the at least one sensor comprises an anvil closure load sensor located in the first jaw member and in communication with the control unit, wherein the anvil closure load sensor senses a load on the first jaw member due to closure of the second jaw member; and
the memory device of the control unit stores data from the anvil closure load sensor.
9. The system of claim 5 , wherein the first jaw member comprises a channel for carrying a replaceable staple cartridge.
10. The system of claim 9 , wherein:
the at least one sensor comprises a cartridge present sensor in the end effector and in communication with the control unit, wherein the cartridge present sensor senses whether the staple cartridge is present in the end effector; and
the memory device of the control unit stores data from the cartridge present sensor.
11. The system of claim 9 , wherein:
the at least one sensor comprises a cartridge condition sensor in the end effector and in communication with the control unit, wherein the cartridge condition sensor senses a condition of the staple cartridge; and
the memory device of the control unit stores data from the cartridge condition sensor.
12. The system of claim 4 , wherein:
the at least one sensor comprises a firing trigger sensor in communication with the control unit, wherein the firing trigger sensor senses actuation of the firing trigger; and
the memory device of the control unit stores data from the firing trigger sensor.
13. The system of claim 4 , wherein:
the at least one sensor comprises an articulation sensor in communication with the control unit, wherein the articulation sensor senses articulation of the end effector; and
the memory device of the control unit stores data from the articulation sensor.
