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 invention claimed is:

1. A handle assembly for an endoscopic device, the handle assembly comprising:
a housing, including:
a distal portion configured for handling by a user, and
a proximal portion having a first mounting surface;

an attachment assembly, including:
a second mounting surface configured to engage the first mounting surface,
a strap receiver having a first side and a second side, the second side being opposite the first side,
a strap, including:
a base end, wherein the base end is at the first side of the strap receiver, and
a free end configured for:
receipt by the strap receiver, such that the free end is fixed relative to the second side of the strap receiver, withdrawal of the free end from the strap receiver being blocked by the strap receiver to form a loop with the strap and the strap receiver, the loop being configured to secure a portion of another endoscopic device to the housing, and
release by the strap receiver to form a gap in the loop to permit the free end to move relative to the strap receiver.

2. The handle assembly of claim 1 , wherein:
the strap receiver includes a recess defined by a plurality of surfaces of the strap receiver,
the free end of the strap includes one or more protruding portions, and
upon receipt of one or more protruding portions in the recess, one or more of the plurality of surfaces engages the one or more protruding portions to block withdrawal of the one or more protruding portions through the recess.

3. The handle assembly of claim 2 , wherein:
the free end of the strap includes a first surface and a second surface, the second surface being opposite the first surface, and
the one or more protruding portions includes a first portion protruding from the first surface and a second portion protruding from the second surface.

4. The handle assembly of claim 1 , wherein:
the strap receiver includes a three-sided recess defined by surfaces of the strap receiver,
the strap includes a central section between the base end and the free end,
the free end includes one or more laterally protruding portions protruding relative to the central section of the strap, and
the three-sided recess is configured to receive the central section of the strap.

5. The handle assembly of claim 4 , wherein the three-sided recess is formed by a U-shaped portion of the strap receiver.

6. The handle assembly of claim 1 , wherein the strap receiver includes a longitudinally extending concave section for receiving and securing the portion of the other endoscopic device to the housing.

7. The handle assembly of claim 1 , wherein the strap receiver shields the free end of the strap from contacting the base end of the strap.

8. A handle assembly for an endoscopic device, the handle assembly comprising:
a housing, including:
a distal portion configured to be handled by a user, and
a proximal portion having a first mounting surface;

an attachment assembly, including:
a second mounting surface configured to engage the first mounting surface,
a strap, including:
a base end, and
a free end,

a strap receiver having a first side and a second side, the second side being opposite the first side, wherein the strap receiver is configured to selectively secure the free end of the strap to the strap receiver, wherein:
in a first state, the strap and the strap receiver form a loop configured to secure a portion of another endoscopic device to the housing, and
in a second state, a gap between the free end of the strap and the strap receiver allows for passage therethrough of the portion of the other endoscopic device.

9. The handle assembly of claim 8 , wherein:
the strap receiver includes a plurality of surfaces that define a recess,
the free end of the strap includes one or more protruding portions, and
upon receipt of one or more protruding portions in the recess, one or more of the plurality of surfaces engages the one or more protruding portions to block movement of the one or more protruding portions through the recess.

10. The handle assembly of claim 9 , wherein:
the free end of the strap includes a first surface and a second surface, the second surface being opposite the first surface, and
the one or more protruding portions includes a first portion protruding from the first surface and a second portion protruding from the second surface.

11. The handle assembly of claim 9 , wherein the strap receiver includes a longitudinally extending concave section for receiving and securing the portion of the other endoscopic device to the housing.

12. The handle assembly of claim 8 , wherein:
the strap receiver includes a three-sided recess,
the strap includes a central section between the base end and the free end,
the free end includes one or more laterally protruding portions protruding relative to the central section of the strap, and
the three-sided recess is configured to receive the central section of the strap.

13. The handle assembly of claim 12 , wherein the three-sided recess is formed by a U-shaped portion of the strap receiver.

14. The handle assembly of claim 8 , wherein the strap receiver shields the free end of the strap from contact with the base end of the strap.

15. A handle assembly for an endoscopic device, the handle assembly comprising:
a housing, including:
a distal portion configured for handling by a user, and
a proximal portion having a first mounting surface;

an attachment assembly, including:
a base having a second mounting surface configured to engage the first mounting surface, wherein the base is directly secured to the proximal portion by one or more mechanical fasteners, and wherein the base includes a recess, and
a strap, wherein the strap includes:
a fixed end, wherein the fixed end is received in the recess of the base, and receipt of the fixed end in the recess fixedly couples the fixed end to the base such that the fixed end is positionally fixed relative to the base, and
a free end, wherein the free end is movable relative to the fixed end to wrap the strap around a portion of another endoscopic device for securing the portion of the other endoscopic device to the housing.

16. The handle assembly of claim 15 , wherein the one or more mechanical fasteners includes a plurality of screws.

17. The handle assembly of claim 15 , wherein the strap is a unitary, monolithic member.

18. The handle assembly of claim 15 , wherein the recess comprises a groove.

19. The handle assembly of claim 18 , wherein the fixed end of the strap includes a protruding portion configured to be received in the groove.

20. The handle assembly of claim 19 , wherein the base includes a slot, and wherein a portion of the strap is received in the slot when the protruding portion is received in the groove.
