Abstract

A surgical instrument operable to sever tissue includes a body assembly and a selectively coupleable end effector assembly. The end effector assembly may include a transmission assembly and an end effector. The body assembly includes a trigger and a casing configured to couple with the transmission assembly. An information transmission system transmits instrument information received from a sensor, for example, to a secure server via a secure gateway connected to the instrument. The instrument may be previously tested on a calibration kit to pre-determine and load surgeon-specific settings onto the instrument prior to use.

First claim

We claim:

1. A surgical system, comprising:
(a) a generator configured to store a set of calibrated settings associated with a user key, and wherein the generator is further configured to operate under a predetermined mode of operation;
(b) a surgical device configured for use during a surgical procedure, wherein the surgical device is in communication with the generator, wherein the generator is configured to power the surgical device during the surgical procedure, wherein the surgical device comprises:
(i) an end effector configured to operate on tissue, wherein the end effector comprises a blade;
(ii) at least one sensor configured to gather usage data acquired during use of the surgical device, wherein the at least one sensor is configured to measure information about the blade;

(c) a user interface in communication with the generator and configured to receive the user key that is used to recall the set of calibrated settings from the generator; and
(d) a calibration kit that includes at least one testable material having known parameters and characteristics,
wherein the predetermined mode of operation is a calibration mode, and
wherein the information about the blade is a blade pressure, a steadiness of the blade, and a speed of the blade.

2. The surgical system of claim 1 , wherein the generator is incorporated into the surgical device.

3. The surgical system of claim 1 , wherein the predetermined mode of operation is a surgical procedure mode.

4. The surgical system of claim 3 , wherein the end effector is further configured using the set of calibrated settings.

5. The surgical system of claim 1 , wherein the at least one testable material comprises at least one testable part from a testable source.

6. The surgical system of claim 1 , wherein the set of calibrated settings is determined based on the use of the end effector on the testable material by a user associated with the user key.

7. The surgical system of claim 1 , wherein the at least one testable material is synthetic.

8. The surgical system of claim 1 , wherein the at least one testable material is organic.

9. A method for storing calibrated settings on a surgical instrument in communication with a generator, the surgical instrument including a selected detachable transmission assembly extending distally from an instrument body, wherein a selected end effector is disposed at a distal end of the transmission assembly, wherein the method comprises the steps of:
(a) coupling an end effector assembly with the instrument body to provide a first assembled surgical instrument;
(b) using the first assembled surgical instrument on material of a calibration kit while the generator is in a calibration mode, wherein the generator is configured to establish a calibrated use setting based on the act of using the first assembled surgical instrument;
(c) associating the calibrated use setting with a user key; and
(d) storing the calibrated use setting in the generator,
wherein the calibrated use setting is at least one of a force and an average speed, wherein the force is applied while using the first assembled surgical instrument, and wherein the average speed is an average blade speed while using the first assembled surgical instrument.

10. The method of claim 9 , further comprising:
(a) de-coupling the end effector assembly from the instrument body;
(b) coupling another end effector assembly with the instrument body to provide a second assembled surgical instrument;
(c) retrieving the calibrated use setting from the generator with the user key; and
(d) using the second assembled surgical instrument in a surgical procedure, wherein the generator is configured to drive the end effector in accordance with the calibrated use setting.
