Abstract

A medical device handle may include an elongated handle housing, a rotatable collar disposed about the handle housing, a rotatable control knob disposed about the collar, and a slidable door disposed about the collar. The door may be rotatably locked to the collar to prevent relative rotation between the door and the collar. The door may slidable from a closed position to a first open position, and slidable from the first open position to a second open position.

Claims

1. A medical device handle, comprising:

an elongated handle housing having a radially-extending transverse ridge disposed about its circumference;

a rotatable collar disposed about a proximal portion of the handle housing, a distal end of the collar abutting a proximally-facing surface of the ridge;

a rotatable control knob disposed at a proximal end of the handle housing; and

a slidable door disposed about a distal portion of the collar.

2. The medical device handle of claim 1, wherein the collar is selectively rotatable about the handle housing.

3. The medical device handle of claim 1, wherein the control knob is selectively rotatable about a longitudinal axis of the handle housing.

4. The medical device handle of claim 1, wherein the collar includes a radially-extending transverse flange portion disposed about a central portion of the collar;

wherein the flange portion spaces the control knob longitudinally from the door.

5. The medical device handle of claim 1, wherein the door is rotatably locked to the collar.

6. The medical device handle of claim 5, wherein the collar includes a plurality of recessed slots in an outer surface thereof, and the door includes a plurality of alignment protrusions extending radially inward from an inner surface thereof;

wherein the plurality of alignment protrusions engage the plurality of recessed slots and prevent relative rotation between the collar and the door.

7. The medical device handle of claim 6, wherein the door is slidable between a closed position wherein the door substantially covers the distal portion of the collar and is engaged with the handle housing to prevent rotation of the door relative to the handle housing, and a first open position wherein the distal portion of the collar is partially uncovered and the door is disengaged from the handle housing such that rotation of the door relative to the handle housing is permitted.

8. The medical device handle of claim 7, wherein in the first open position, a first protruding stop extending radially inward from an inner surface of the door abuts the proximally-facing surface of the ridge.

9. The medical device handle of claim 8, wherein rotation of the door in the first open position translates the first protruding stop along the proximally-facing surface of the ridge.

10. The medical device handle of claim 9, wherein the ridge further includes an opening extending therethrough along an outer surface of the handle housing.

11. The medical device handle of claim 10, wherein the door further includes a second protruding stop extending radially inward from an inner surface of the door and a third protruding stop extending radially inward from an inner surface of the door, and the door is further slidable to a second open position distal of the first open position;

wherein the first protruding stop passes distally through the opening in the ridge and the door is further translated distally until the second and third protruding stops abut the proximally-facing surface of the ridge in the second open position.

12. The medical device of claim 11, wherein rotation of the door in the second open position translates the second and third protruding stops along the proximally-facing surface of the ridge.

13. The medical device of claim 9, wherein rotation of the door in the first open position translates a first shaft longitudinally within the handle housing.

14. The medical device of claim 12, wherein rotation of the door in the second open position translates a second shaft longitudinally within the handle housing.

15. The medical device handle of claim 7, wherein the handle housing includes at least one guide stop extending radially outward from an outer surface of the handle housing;

wherein the door includes at least one groove in an inner surface thereof;

wherein the at least one groove is configured to engage the at least one guide stop to prevent rotation of the door in the closed position.

16. The medical device handle of claim 1, further comprising a means for actuating a medical device disposed distally of the medical device handle, the means being disposed within the handle housing and translating longitudinally in response to rotation of the control knob.

17. The medical device handle of claim 17, wherein the means for actuating includes an interlocking element extending radially outward from the longitudinal axis, the interlocking element having an engaged configuration and a disengaged configuration;

wherein in the engaged configuration, the interlocking element physically prevents the collar from rotating;

wherein in the disengaged configuration, the interlocking element permits the collar to rotate.
