Abstract

In various instances, the surgical instrument can include a data storage protocol and/or at least one security feature. The surgical instrument can include a locking circuit, for example. In various instances, the surgical instrument can include sensors and/or magnets for detecting various characteristics of the surgical instrument, surgical operation, and/or surgical site. The surgical instrument can require a temporary access code for operating and/or can be selected for connection to an external display. A surgical system can include a first modular component, a second modular component, and a feedback system. The feedback system can include an engagement sensor, which can detect the engagement and/or degree of engagement of the first modular component and the second modular component.

Claims

1. A surgical system, comprising:

a handle, comprising;

a trigger; and

an electric motor;

an end effector comprising a plurality of deployable fasteners;

a shaft intermediate said handle and said end effector;

a microcontroller configured to record data during a surgical procedure; and

a data security system, comprising;

a data exchange port on said handle, wherein said data exchange port is in signal communication with said microcontroller, and wherein said data exchange port comprises a mechanical lock; and

a data exchange input comprising a key, wherein said key is configured to unlock said mechanical lock when said data exchange input engages said data exchange port.

2. A surgical system, comprising:

a first modular component, comprising;

a first attachment portion; and

an electric motor;

a second modular component, comprising;

a second attachment portion moveable between a plurality of positions relative to said first attachment portion, wherein said plurality of positions comprises a disengaged position and an engaged position, and wherein said second modular component is secured relative to said first modular component when said second attachment portion is in said engaged position; and

a drivable element in communication with said electric motor when said second modular component is secured relative to said first modular component; and

a feedback system, comprising;

an engagement sensor configured to detect at least three engagement states of said second attachment portion relative to said first attachment portion;

a display; and

a microcontroller in signal communication with said engagement sensor and said display, wherein said microcontroller is configured to communicate the detected state of said second attachment portion to said display.

3. The surgical system of claim 2, wherein said plurality of positions further comprises a partially-engaged position, wherein said partially-engaged position is intermediate said disengaged position and said engaged position, and wherein said engagement sensor is configured to detect said partially-engaged position.

4. The surgical system of claim 2, wherein said microcontroller is in signal communication with said electric motor, wherein said electric motor is configured to drive said drivable element during a firing stroke, and wherein said microcontroller prevents the firing stroke until said engagement sensor detects said engaged position.

5. The surgical system of claim 2, wherein said first modular component comprises a handle, and wherein said second modular component comprises a shaft and an end effector.

6. A surgical system, comprising:

a first modular component comprising an electric motor;

a second modular component;

means for securing said first modular component relative to said second modular component; and

a feedback system, comprising;

means for detecting at least three degrees of engagement of said first modular component and said second modular component;

means for displaying information; and

means for communicating the degree of engagement detected by said means for detecting to said means for displaying information.
