17. The connector of claim 1 , wherein the seal is of a color contrasting with a color of the base.

18. The connector of claim 1 , wherein the seal is permanently, adhesively and chemically bond molded to the inner surface of the proximal most end of the base.

19. A connector for connecting an instrument tip with a laparoscopic tube end, the connector comprising:

a base forming a body of the connector, the base having a lumen configured to accommodate an instrument tip actuator therein, the base comprising at least one of a recess and protrusion on the inner surface of a proximal most end of the base; and

a seal permanently mechanically bond molded to the at least one of the recess and protrusion, wherein the seal is configured to deform upon connection of the connector with the tube end, such that upon disengagement of the connector and the tube end, the seal is deformed such that the tube end and the tip cannot be securely reattached.

20. A laparoscopic device, comprising:

a tube having a lumen and a slidable inner shaft;

an instrument tip configured to be affixed to a distal end of the tube; and

a connector affixed to a proximal end of the instrument tip having a back hub and seal permanently bonded to the back hub, the seal configured to deform upon engaging the tube such that upon disengagement of the connector and the tube, the seal is deformed such that the tube and the tip cannot be securely reattached.

21. The laparoscopic device of claim 20 , wherein the instrument tip and the connector are unitarily formed together.

22. The laparoscopic device of claim 21 , wherein the tube electrically insulates and fluidically seals the inner shaft from the outside of the tube end.

23. The laparoscopic device of claim 20 , wherein the back hub is one of threaded, press-fit, bayonet, ball-and-detent, barrel pin, dog-tooth ratchet mechanism.

24. The laparoscopic device of claim 20 , wherein the seal includes at least one fluid-encased pocket, wherein upon deformation of the at least a portion of the seal, the pocket is ruptured and fluid is released.

25. The laparoscopic device of claim 20 , wherein the seal is at least partially visible when the connector is connected to the tube.

26. The laparoscopic device of claim 20 , wherein at least one of the back hub and seal is one of permanently deformed, dissolved and destroyed after a predetermined number of uses or predetermined amount of time.

27. The laparoscopic device of claim 20 , wherein the back hub material is more rigid than the seal material.

28. A connector for connecting an instrument tip with a laparoscopic tube end, the connector comprising:

a base forming a body of the connector, the base having a lumen configured to accommodate an instrument tip actuator therein; and

a seal configured to deform upon connection of the connector with the tube end such that upon disengagement of the connector and the tube end, the seal is deformed such that the tube end and the tip cannot be securely reattached,
