Abstract

An apparatus and system are disclosed for indicating relative positions of elements in a surgical apparatus. The indicating elements can include electrical circuitry for activating visual, audible or tactile indicators, thereby alerting the user that an event has occured with respect to the instrument.

Claims

1. A system for performing surgery, comprising:

a control box which includes internal circuitry;

a surgical instrument including a distal element and means for sensing a position or condition of said distal element;

means associated with said surgical instrument for transmitting said sensed position or condition to said internal circuitry of said control box; and

means for transmitting said sensed position or condition from said internal circuitry of said control box to a video monitor for display thereon, wherein said sensed position or condition is displayed on said video monitor as an icon or symbol, further comprising a voltage source for generating a voltage contained entirely within said surgical instrument.

2. The system as recited in claim 1, further comprising an endoscope or laparoscope for obtaining an image of a surgical site, wherein said control box further comprises means for receiving said image from said endoscope or laparoscope and transmitting said image to said video monitor.

3. A system as recited in claim 1, wherein said means for transmitting to said control box is a cable.

4. A system as recited in claim 1, wherein said means for transmitting to said control box is a transmitter associated with said surgical instrument and receiving means associated with said control box for receiving transmissions from said transmitter, said voltage source providing power to said transmitter.

5. A system as recited in claim 1, wherein said icon or symbol is displayed in color.

6. A system as recited in claim 1, wherein said icon or symbol flashes on said video monitor.

7. A system as recited in claim 1, wherein said distal element contains a surgical staple.

8. A system as recited in claim 1, wherein said voltage source is a battery.

9. A system as recited in claim 1, wherein said icon or symbol depicts a surgical instrument.

10. A system for performing surgery, comprising:

i) a surgical apparatus having a housing and a tool mechanism extending from said housing, said tool mechanism being movable from a first position to a second position;

ii) means for generating a first signal when said tool mechanism is in said second position; and

iii) means for transmitting said first signal to a video monitor remote from the surgical apparatus, said sensed position or condition being displayed on said video monitor as an icon or symbol, further comprising a voltage source for generating a voltage contained entirely within said surgical instrument.

11. A system as recited in claim 10, wherein said icon or symbol is displayed in color.

12. A system as recited in claim 10, wherein said icon or symbol flashes on said video monitor.

13. A system as recited in claim 10, wherein said icon or symbol depicts said tool mechanism.

14. A system as recited in claim 10, wherein said tool mechanism contains a surgical staple.

15. A system as recited in claim 10, wherein said voltage source is a battery.

16. A system as recited in claim 10, wherein said icon or symbol depicts a surgical instrument.
