Abstract

An actuation mechanism for an endoscope is disclosed. The actuation mechanism includes a housing configured to be attached to a handle of the endoscope and a thumbwheel coupled to the housing. Rotation of the thumbwheel causes longitudinal translation of an elongated medical device through a working channel of the endoscope. In some instances, the actuation mechanism includes a drive wheel and/or a roller wheel, wherein the elongate medical device is compressively positioned between the roller wheel and/or the drive wheel. Rotation of the thumbwheel may cause the drive wheel and/or the roller wheel to rotation in opposite rotational directions.

Claims (32)

1. An actuation mechanism for an endoscope, comprising:

a housing configured to be attached to a handle of an endoscope;

a first thumbwheel coupled to the housing; and

a first connection tube having a proximal end coupled to the housing and a distal end configured to connect with an access port on the handle of the endoscope;

the first thumbwheel is configured such that rotation of the first thumbwheel causes longitudinal translation of a first elongated medical device through the first connection tube, out the distal end of the first connection tube, and into and through the working channel of the endoscope wherein the housing includes a channel extending from an outer surface of the housing into a portion of a wall of the housing, wherein the channel is configured to accept a proximal end of a tubular member of the first elongated medical device, and wherein the proximal end of the tubular member of the first elongated medical device is fixedly attached to the channel, and wherein the channel is configured to accept an elongate member of the first elongated medical device extending within a lumen of the tubular member of the first elongated medical device.

2. The actuation mechanism of claim 1 , further comprising a first drive wheel coupled to the housing, the first thumbwheel engaging the first drive wheel, wherein rotation of the first thumbwheel is configured to cause rotation of the first drive wheel.

3. The actuation mechanism of claim 2 , further comprising a first roller wheel coupled to the housing, wherein an outer circumferential surface of the first roller wheel is positioned adjacent to an outer circumferential surface of the first drive wheel such that the first elongated medical device may be positioned between the outer circumferential surface of the first roller wheel and the outer circumferential surface of the first drive wheel, and wherein rotation of the first thumbwheel is configured to cause rotation of the first drive wheel to move the first elongated medical device through the working channel of the endoscope.

4. The actuation mechanism of claim 3 , wherein the first roller wheel and the first drive wheel are configured to cooperatively exert a compressive force on the first elongated medical device to frictionally engage the first elongated medical device therebetween.

5. The actuation mechanism of claim 4 , wherein the first thumbwheel includes a circumferential surface, and wherein each of the first thumbwheel, the first drive wheel and the first roller wheel have respective bands of material extending therearound.

6. The actuation mechanism of claim 4 , wherein the housing includes an inner housing and an outer housing, wherein the first thumbwheel, the first drive wheel and the first roller wheel are positioned between the inner housing and the outer housing.

7. The actuation mechanism of claim 3 , further comprising a second thumbwheel coupled to the housing, a second drive wheel coupled to the housing and a second roller wheel coupled to the housing, and wherein the second thumbwheel engages the second drive wheel, and wherein rotation of the second thumbwheel is configured to cause longitudinal translation of a second elongated medical device through a working channel of the endoscope.

8. The actuation mechanism of claim 2 , wherein the first thumbwheel includes a first diameter and the first drive wheel includes a second diameter, and

wherein the second diameter is less than the first diameter.

9. The actuation mechanism of claim 1 , further comprising a first roller wheel coupled to the housing, wherein an outer circumferential surface of the first roller wheel is positioned adjacent to an outer circumferential surface of the first thumbwheel such that the first elongated medical device may be positioned between the outer circumferential surface of the first roller wheel and the outer circumferential surface of the first thumbwheel, and wherein rotation of the first thumbwheel is configured to cause rotation of the first roller wheel to move the first elongated medical device through the working channel of the endoscope.

10. The actuation mechanism of claim 1 , further comprising a rotation cap coupled to the housing, and wherein a proximal end of the elongate member is attached to the rotation cap, and wherein rotation of the rotation cap is configured to move the elongate member within the lumen of the tubular member of the first elongated medical device.

11. An endoscopic medical device, comprising:

a handle having a proximal end region and a distal end region;

an elongate shaft coupled to the distal end region of the handle and extending distally therefrom;

an actuation assembly coupled to the proximal end region of the handle, wherein the actuation assembly includes:

a housing;

a first thumbwheel coupled to the housing;

a second thumbwheel coupled to the housing;

a first connection tube having a proximal end coupled to the housing and a distal end configured to connect with an access port of the handle;

a second connection tube having a proximal end coupled to the housing and the second connection tube having a a distal end configured to connect with the access port of the handle, where the first and second connection tubes are different structures;

the first thumbwheel is configured such that rotation of the first thumbwheel causes a first elongated medical device to translate through the first connection tube, out the distal end of the first connection tube and into and through the elongate shaft;

the second thumbwheel is configured such that rotation of the second thumbwheel causes a second medical device to translate through the second connection tube, out the distal end of the second connection tube and into and through the elongate shaft wherein the actuation assembly further includes a first drive wheel and a first roller wheel coupled to the housing, the first drive wheel configured to be rotated by the first thumbwheel, and

wherein the actuation assembly further includes and a second drive wheel and a second roller wheel coupled to the housing, the second drive wheel configured to be rotated by the second thumbwheel, and wherein the first drive wheel and the first roller wheel are configured to cooperatively exert a force on the first medical device positioned therebetween, and wherein the second drive wheel and the second roller wheel are configured to cooperatively exert a force on the second medical device positioned therebetween.

12. The endoscopic medical device of claim 11 , wherein the rotation of the first thumbwheel to translate the first medical device occurs independently of the rotation of the second thumbwheel to translate the second medical device.

13. The endoscopic medical device of claim 11 , wherein rotation of the first thumbwheel is configured to rotate the first drive wheel and the first roller wheel in opposite rotational directions to translate the first elongated medical device through the elongate shaft, and

wherein rotation of the second thumbwheel is configured to rotate the second drive wheel and the second roller wheel in opposite rotational directions to translate the second elongated medical device through the elongate shaft.

14. The endoscopic medical device of claim 11 , wherein the first thumbwheel includes a first diameter and the first drive wheel includes a second diameter, and

wherein the second diameter is less than the first diameter.
