## Abstract

An endoscopy device (1) with an endoscope (2) and a camera control unit (12) is provided. The endoscope (2) has an endoscope shaft (3) and an endoscope head (4), and the endoscope shaft (3) is made of a metallic material. Electronics (8) are arranged in the endoscope head (4) and are connected to an attachment cable (10), and the electronics (8) and the attachment cable (10) are shielded by an electronics shield (14). A galvanic barrier (15) is set up between the electronics shield (14) and the endoscope shaft (3) and couples the endoscope shaft (3) capacitively to the electronics shield (14).

## Claims

### Claim 1

An endoscope (2) comprising: an endoscope shaft (3), an endoscope head (4) arranged at a proximal end of the endoscope shaft (3), an attachment cable (10) arranged proximally on the endoscope head (4), electronics (8) arranged in the endoscope head (4), an attachment plug (11) at a proximal end of the attachment cable (10), an electronics shield (14) that shields the electronics (8), wherein the electronics shield (14) also extends in the attachment cable (10) and shields at least one line (27) extending through the attachment cable (10) between the attachment plug (11) and the electronics (8), the endoscope shaft (3) is made of a metallic material, a galvanic barrier (15) is disposed between the electronics shield (14) and the endoscope shaft (3) and couples the endoscope shaft (3) capacitively to the electronics shield (14), and the endoscope shaft (3) is mechanically separable from the endoscope head at the galvanic barrier (15).

### Claim 2 (depends on 1)

The endoscope (2) as claimed in claim 1, wherein at least one electronics component is electrically connected to the electronics (8) and is arranged in a distal end of the endoscope shaft (3), and the endoscope shaft (3) acts as a shield for the at least one electronics component (8).

### Claim 3 (depends on 2)

The endoscope (2) as claimed in claim 2, wherein the at least one electronics component includes at least one of an image sensor (7), a temperature sensor or a heating element.

### Claim 4 (depends on 2)

The endoscope (2) as claimed in claim 2, further comprising an isolation layer (21) provided between a wall (19) of the endoscope shaft (3) and the at least one electronics component.

### Claim 5 (depends on 1)

The endoscope (2) as claimed in claim 1, wherein the endoscope head (4) is designed as a handle, and the galvanic barrier (15) is formed between a grip area (17) and the endoscope shaft (3).

### Claim 6 (depends on 1)

The endoscope (2) as claimed in claim 1, wherein the galvanic barrier (15) forms a high pass filter that limits a frequency of below 1 MHz to be transmitted therethrough.

### Claim 7 (depends on 1)

The endoscope (2) as claimed in claim 1, wherein the galvanic barrier (15) is formed by a film (16).

### Claim 8 (depends on 7)

The endoscope (2) as claimed in claim 7, wherein the film (16) is between the endoscope shaft (3) and a metal part electrically connected to the electronics shield (14).

### Claim 9 (depends on 1)

The endoscope (2) as claimed in claim 1, wherein the attachment cable (10) has a video line.

### Claim 10 (depends on 1)

The endoscope (2) as claimed in claim 1, wherein the electronics shield (14) has, toward the endoscope shaft (3), an at least one of electrical or optical passage (29) which leads from the electronics to an interior of the endoscope shaft (3).

### Claim 11 (depends on 1)

An endoscopy device (1) comprising an endoscope (2) as claimed in claim 1, and a camera control unit (12) to which the attachment cable (10) is attached, wherein the at least one line (27) is galvanically isolated from the camera control unit (12).

### Claim 12 (depends on 11)

The endoscopy device (1) as claimed in claim 11, wherein the electronics shield (14) is coupled capacitively to a housing (25) of the camera control unit (12).

### Claim 13 (depends on 12)

The endoscopy device (1) as claimed in claim 12, wherein the electronics shield (14) is coupled capacitively to the housing (25) of the camera control unit (12) with a capacitance (C2) greater than a capacitance (C1) of the galvanic barrier (15).

### Claim 14 (depends on 11)

The endoscopy device (1) as claimed in claim 11, wherein the galvanic barrier (15) and a coupling of the electronics shield (14) to a housing (25) form a series connection of capacitors between the housing (25) and the endoscope shaft (3).
