Abstract

Various apparatuses to attach a first medical device to a second medical device are described that allow the physician to grasp only a single device while the other device remains securely attached to the one being grasped. The apparatuses, once they are attached to the first medical device, are designed to be easily and quickly attached and detached to a second medical device, normally only requiring the use of one hand. Furthermore, the apparatuses oftentimes include a base that can easily couple and decouple from the portion that is attached to the second medical device so that if the need arises to separately use the second medical device, it can be decoupled from the first medical device without completely removing the apparatus from the second medical device.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. An apparatus for selectively securing a first medical device to a second medical device, comprising:
a clamp positioned on the first medical device, the clamp including a first holding portion and a second holding portion, the first holding portion and the second holding portion each configured to open to receive the second medical device between the first and second holding portions; and
a locking mechanism that is selectively positioned to prevent the first and second holding portions from opening.

2. The apparatus of claim 1 , wherein one of the first and second holding portions includes a tab that is selectively positioned in a catch, and the locking mechanism includes a pawl that secures the tab in the catch.

3. The apparatus of claim 2 , wherein the pawl is mounted on a rotating barrel.

4. The apparatus of claim 3 , wherein the barrel is rotatable between a first position where the pawl does not prevent the tab from being removed from the catch and a second position where the pawl does prevent the tab from being removed from the catch.

5. The apparatus of claim 4 , wherein the pawl includes a ramp and a ridge.

6. The apparatus of claim 5 , wherein the pawl is configured such that as the barrel transitions from the first position to the second position, the ramp is configured to urge the pawl against the catch until the pawl is positioned on the ridge.

7. The apparatus of claim 1 , wherein one of the first and second holding portions is fixed to a clamp base and another holding portion moves with respect to the clamp base.

8. The apparatus of claim 1 , wherein each of the first and second holding portions is arcuately shaped.

9. The apparatus of claim 1 , wherein each of the first and second holding portions comprises deformable material.

10. The apparatus of claim 1 , wherein each of the first and second holding portions includes a first end associated with a clamp base, and a second free end.

11. The apparatus of claim 10 , wherein the second free end of each of the first and second holding portions includes a radially outward flare configured to guide the second medical device into engagement with the first and second holding portions.

12. An apparatus for selectively securing a first medical device to a second medical device, comprising:
a clamp positioned on the first medical device, the clamp including a first arcuate holding portion and a second arcuate holding portion, wherein a first end of the first holding portion is fixedly coupled to a clamp base, and a first end of the second holding portion is movably coupled to the clamp base; and
a locking mechanism that is selectively positioned to prevent the first end of the second holding portion from moving relative to the clamp base.

13. The apparatus of claim 12 , wherein the second holding portion includes a tab that is selectively positioned in a catch positioned on the clamp base, and the locking mechanism includes a pawl that secures the tab in the catch.

14. The apparatus of claim 13 , wherein the pawl is mounted on a rotating barrel.

15. The apparatus of claim 14 , wherein the pawl includes a ramp and a ridge.

16. The apparatus of claim 15 , wherein the pawl is configured such that as the barrel is rotated from a first position to a second position, the ramp is configured to urge the pawl against the catch until the pawl is positioned on the ridge.

17. The apparatus of claim 12 , wherein each of the first and second holding portions comprises deformable material.

18. The apparatus of claim 12 , wherein each of the first and second holding portions includes a second free end.

19. The apparatus of claim 18 , wherein the second free end of each of the first and second holding portions includes a radially outward flare configured to guide the second medical device into engagement with the first and second holding portions.

20. The apparatus of claim 12 , wherein the first and second holding portions are biased towards each other.
