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).
Claims14
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).
