## Abstract

An endoscope system includes an endoscope including an insertion portion including a bending portion, a grasping portion arranged at a proximal end portion of the insertion portion, and an electric actuator configured to bend the bending portion, and an operation unit including an operation member configured to operate the electric actuator and a transmission member configured to wirelessly transmit operation information of the operation member to the electric actuator.

## Claims

### Claim 1

An endoscope system comprising:
an endoscope comprising:
an insertion portion including a bending portion;
a grasping portion arranged on a proximal end side of the insertion portion; and
an electric actuator configured to bend the bending portion; and
an operation unit comprising:
an operation member configured to operate the electric actuator; and
a transmission member configured to wirelessly transmit operation information of the operation member to the electric actuator.

### Claim 2 (depends on 1)

The endoscope system according to claim 1, wherein
the transmission member is a transmission circuit configured to transmit the operation information using a wireless signal, and
the endoscope comprises a reception circuit configured to receive the wireless signal.

### Claim 3 (depends on 1)

The endoscope system according to claim 1, further comprising an image processor electrically connected with the grasping portion of the endoscope via a universal cord, wherein
the transmission member is a transmission circuit configured to transmit the operation information using a wireless signal,
the image processor comprises a reception circuit configured to receive the wireless signal, and
the operation information is transmitted to the electric actuator via the universal cord.

### Claim 4 (depends on 1)

The endoscope system according to claim 1, wherein
a magnet that moves according to operation of the operation member of the operation unit is the transmission member, and
the endoscope comprises a magnetic sensor configured to detect a magnetic field change of the magnet, which is the operation information.

### Claim 5 (depends on 1)

The endoscope system according to claim 1, wherein the operation unit is fixed in any position on a surface of the grasping portion.

### Claim 6 (depends on 1)

The endoscope system according to claim 1, wherein the endoscope system comprises a belt body for fixing a hand of a surgeon to the grasping portion.

### Claim 7 (depends on 1)

The endoscope system according to claim 1, wherein the grasping portion is a substantial sphere or a substantial elliptical body.

### Claim 8 (depends on 1)

The endoscope system according to claim 1, wherein
a first mark corresponding to a bending direction of the bending portion is attached to the grasping portion, and
a second mark corresponding to an operation direction is attached to the operation unit.

### Claim 9 (depends on 1)

The endoscope system according to claim 1, wherein
an elongated recess or an elongated projection corresponding to a bending direction of the bending portion is present in the grasping portion, and
an elongated projection or an elongated recess that corresponds to an operation direction and fits into the recess or the projection is present in the operation unit.

### Claim 10

An endoscope comprising:
an insertion portion including a bending portion;
a grasping portion arranged at a proximal end portion of the insertion portion; and
an electric actuator configured to bend the bending portion based on operation information wirelessly transmitted from an operation unit.

### Claim 11

An operation unit comprising:
an operation member configured to operate an electric actuator of an endoscope including an insertion portion including a bending portion, a grasping portion arranged at a proximal end portion of the insertion portion, and the electric actuator configured to bend the bending portion; and
a transmission member configured to wirelessly transmit operation information of the operation member to the electric actuator.
