Abstract

An endoscopic deployment device includes a body mountable on an endoscopic device, a communication interface, and a motor. The body has a movable carrier couplable to an elongated end effector device. The effector device has an end effector shaft covered by an outer sheath and an end effector extending from a distal end of the shaft. The sheath is sized and shaped for insertion through a working channel of an endoscopic shaft of the endoscopic device. The body has a carrier channel sized for the carrier to slide therein. The end effecter is actuatable between open and closed positions by sliding the carrier in the carrier channel which in turn slides the sheath over the end effector shaft to uncover/cover the end effector. Rotation of a drive shaft of the motor is sliding the carrier in the carrier channel and actuating the end effector in response to a signal.

First claim

The invention claimed is:

1. An endoscopic deployment device, comprising:
a body mountable on an endoscopic device, the body having a movable carrier couplable to an elongated end effector device, the elongated end effector device having an end effector shaft covered by an outer sheath and an end effector extending from a distal end of the end effector shaft, the outer sheath being sized and shaped for insertion through a working channel of an endoscopic shaft of the endoscopic device, the body having a carrier channel sized for the movable carrier to slide therein, wherein the end effector is actuatable between an extended open position and a retracted closed position by sliding the movable carrier in the carrier channel which in turn slides the outer sheath over the end effector shaft to uncover or cover the end effector;
a communication interface extending from the body and configured to be mated with a corresponding communication interface on the endoscopic device on which the body is mounted to receive power therefrom and exchange data therewith; and
a motor having a drive shaft coupled to the movable carrier, wherein the motor is configured to rotate the drive shaft to slide the movable carrier in the carrier channel and actuate the end effector in response to a signal.

2. The endoscopic deployment device of claim 1 , wherein an actuator on the endoscopic device is configured to generate the signal.

3. The endoscopic deployment device of claim 2 , wherein the actuator is a button pad configured to control the motor via the communication interface of the endoscopic deployment device mated with the corresponding communication interface on the endoscopic device.

4. The endoscopic deployment device of claim 1 , wherein the signal is generated in response to an endoscopic sensor reading.

5. The endoscopic deployment device of claim 1 , wherein the motor is a stepper motor.

6. The endoscopic deployment device of claim 5 , wherein the drive shaft has an arm extending orthogonally therefrom coupled to a slot in the movable carrier and the arm has a pin at an end of the arm opposite the drive shaft, the pin being coupled to the slot so that, when the drive shaft rotates, the pin slides in the slot in a direction orthogonal to the carrier channel and the movable carrier slides in the carrier channel.

7. The endoscopic deployment device of claim 5 , wherein the drive shaft is a lead screw coupled to a threaded through hole extending through a portion of the movable carrier parallel to the carrier channel so that, when the drive shaft rotates, the movable carrier slides in the carrier channel.

8. The endoscopic deployment device of claim 5 , wherein a pinion gear is coupled to the drive shaft and to a rack that is an integral portion of the movable carrier, wherein the pinion gear is configured to drive the rack and slide the movable carrier in the carrier channel.

9. The endoscopic deployment device of claim 1 , wherein the elongated end effector device is a retrieval device for capturing objects at a distal end of the endoscopic shaft.

10. The endoscopic deployment device of claim 1 , wherein the elongated end effector device is a laser fiber or energy fiber for fragmenting or cauterizing objects at a distal end of the endoscopic shaft.

11. The endoscopic deployment device of claim 1 , wherein the elongated end effector device has a handle for coupling to the movable carrier of the endoscopic deployment device, wherein the movable carrier and a slide of the handle are configured to be positioned fully proximally prior to attaching the handle to the endoscopic deployment device.

12. The endoscopic deployment device of claim 1 , wherein the endoscopic device has a proximal communication interface and a distal communication interface and the communication interface of the endoscopic deployment device is compatible with the proximal communication interface of the endoscopic device.
