Medical device having a position indicator
A medical device is described, the medical device comprising a moveable member, moveable between a first position and a second position; an actuating member coupled to the moveable member, directly or indirectly, for manipulating the moveable member, that is for causing the movement of the moveable member; and an indicator mechanism coupled, directly or indirectly, to the actuating member, said indicator mechanism comprising at least two components that interact to produce an indication; the indicator and actuating member being cooperatively operable such that the interaction between the at least two components of the indicator mechanism occurs automatically to automatically indicate advancement of the moveable member to the second position from the first position upon a predetermined actuation of the actuating member.
1. A medical device comprising:
a moveable member that is moveable between an initial position and multiple predetermined positions for transferring at least one component there-between;
an actuator coupled to the moveable member for actuating said moveable member between the initial position and the multiple predetermined positions; and
at least one automatic indicator mechanism coupled to the moveable member for providing multiple indications, each for indicating movement of said moveable member between the initial position and one of said multiple predetermined positions, wherein the at least one indicator mechanism comprises multiple indicator mechanisms, each for providing one of said multiple indications, and
wherein the multiple indicator mechanisms comprise a first indicator mechanism for providing a first indication and a second indicator mechanism for providing a second indication;
said first indication for indicating movement of said moveable member between said initial position and a first predetermined position from said multiple predetermined positions, said movement being sufficient to transfer at least a first component of said at least one component between said initial position and the first predetermined position; and
said second indication for indicating movement of said moveable member between said initial position and a second predetermined position from said multiple predetermined positions, said movement being sufficient to transfer the first component between said initial position and the second predetermined position.
2. The medical device of claim 1 , wherein at least one of the multiple indications comprises an audible indication.
3. The medical device of claim 1 , wherein the at least one indicator mechanism comprises a single indicator mechanism for providing each of said multiple indications.
4. The medical device of claim 1 , wherein the at least one indicator mechanism comprises at least two components that are functional to interact with one another to produce the multiple indications;
wherein the interaction between the at least two components occurs automatically upon actuation of the moveable member, thereby providing an automatic indication of the movement of the moveable member between the initial position and one of said multiple predetermined positions.
5. The medical device of claim 4 , wherein one of the at least two components of the at least one indicator mechanism is coupled to the moveable member.
6. The medical device of claim 5 , wherein said one of the at least two components is indirectly coupled to the moveable member.
7. The medical device of claim 6 , wherein said one of the at least two components is moveable within a housing of the medical device upon actuation of the moveable member.
8. The medical device of claim 7 wherein the device comprises the housing, wherein another of the at least two components comprises a feature of the housing.
9. The medical device of claim 8 , wherein the said one of the at least two components comprises a biased component and the other of the at least two components comprises a non-biased component.
10. The medical device of claim 9 , wherein the biased component comprises a deflectable member and the non-biased component comprises a rigid member.
11. The medical device of claim 10 , wherein the deflectable member comprises a deflectable arm that is a part of a depth selector.
12. The medical device of claim 11 , wherein the rigid member comprises a feature that is integral with the housing.
13. The medical device of claim 1 , wherein the at least one indicator mechanism comprises multiple indicator mechanisms, each for providing one of said multiple indications, wherein each of said multiple indicator mechanisms comprises at least two components.
14. The medical device of claim 13 , wherein at least two of said indicator mechanisms share a component from each of their respective at least two components.
