## Abstract

In one example, a controller configured for use with a medical device, may include a body configured to removably couple to the medical device. The body may include a gear configured to mate with a first actuator of the medical device; and a second actuator, and the actuation of the second actuator may be configured to initiate movement of the gear and the first actuator.

## Claims

### Claim 1

A controller configured for use with a medical device, comprising:
a body configured to removably couple to the medical device, wherein the body comprises:
a first body including:
a first gear configured to mate with a first actuator of the medical device;
a second gear configured to mate with a third actuator of the medical device; and
a second body including:
a second actuator, wherein actuation of the second actuator is configured to initiate movement of the first gear and the first actuator; and
a fourth actuator, wherein actuation of the fourth actuator is configured to wirelessly initiate movement of the second gear and the third actuator;
wherein the second body is U-shaped and configured to (i) directly couple to and abut a handle of the medical device and (ii) wirelessly connect to the first body to initiate movement of the first gear and the first actuator.

### Claim 2 (depends on 1)

The controller of claim 1, wherein the body further comprises a motor communicatively coupleable with the second actuator, and the motor is configured to cause movement of the first gear.

### Claim 3 (depends on 1)

The controller of claim 1, wherein the first gear is circular and includes a lumen; wherein the lumen is configured to receive the first actuator.

### Claim 4 (depends on 1)

The controller of claim 1, wherein the first actuator is a knob configured to articulate a distal portion of the medical device.

### Claim 5 (depends on 1)

The controller of claim 1, wherein the body further comprises:
a first motor in communication with the second actuator;
a third gear fixedly coupled to the first motor and configured to engage with the first gear;
a second motor in communication with the fourth actuator; and
a fourth gear fixedly coupled to the second motor and configured to engage with the second gear.

### Claim 6 (depends on 5)

The controller of claim 5, wherein actuation of the second actuator is configured to initiate clockwise rotation of the first gear and counter-clockwise rotation of the first actuator; wherein actuation of the fourth actuator is configured to initiate clockwise rotation of the second gear and counter-clockwise rotation of the third actuator; and wherein the body further comprises:
a fifth actuator positioned on the second body, wherein actuation of the fifth actuator is configured to wirelessly initiate counter-clockwise rotation of the first gear and clockwise rotation of the first actuator; and
a sixth actuator positioned on the second body, wherein actuation of the sixth actuator is configured to wirelessly initiate counter-clockwise rotation of the second gear and clockwise rotation of the third actuator.

### Claim 7 (depends on 5)

The controller of claim 5, wherein the first motor and the second motor are wirelessly connected to a circuit board positioned within the second body.

### Claim 8 (depends on 1)

The controller of claim 1, wherein the second gear has a larger circumference than the first gear.

### Claim 9 (depends on 1)

The controller of claim 1, wherein each of the first gear and the second gear includes a central lumen and a plurality of gear teeth; wherein the first actuator and the third actuator are a first knob and a second knob, respectively;
wherein a radially-inward facing surface of the first gear is curved to mate with the first knob; and wherein a radially-inward facing surface of the second gear is curved to mate with the second knob.

### Claim 10 (depends on 1)

The controller of claim 1, wherein the second body is configured to couple to a distal portion of the first body.

### Claim 11 (depends on 1)

The controller of claim 1, further comprising a circuit board electrically coupled to the second actuator.

### Claim 12 (depends on 1)

The controller of claim 1, wherein the second actuator is positioned entirely distal to the first actuator and the first gear.

### Claim 13 (depends on 1)

The controller of claim 1, wherein the first gear is positioned within a first groove of the first body; and wherein the second gear is positioned with a second groove of the first body.

### Claim 14 (depends on 1)

The controller of claim 1, wherein the second actuator is configured to be positioned proximate to an umbilicus of the medical device when the controller is coupled to the handle of the medical device.

### Claim 15

An endoscope system comprising:
an endoscope including a handle; and
a controller configured to be coupled to the handle, and uncoupled from the handle, the controller comprising:
a body, wherein the body comprises:
a gear configured to mate with a first actuator of the handle such that rotation of the gear causes rotation of the first actuator;
a second actuator, wherein actuation of the second actuator is configured to initiate rotation of the gear and the first actuator;
a first recess configured to receive a first locking actuator of the endoscope and prevent rotation of the first locking actuator when the body is coupled to the endoscope; and
a second recess configured to receive a second locking actuator of the endoscope and prevent rotation of the second locking actuator when the body is coupled to the endoscope;
wherein the body includes a distal portion configured to wrap around the handle and a proximal portion configured to cover the first actuator.
