Abstract
An endoscopic instrument (1, 134) for inserting into a body of a patient includes a tubular shank (3, 47, 137) and at least two electrical, mechanical and/or optical leads (11, 13, 15, 19, 57, 59, 65, 67, 123, 181) which run through the shank (3, 47, 137). A fluid channel (7, 53) is formed in the shank (3, 47, 137). The instrument includes a sealing device (89) which forms a proximal end of the fluid channel and comprises feed-throughs (93, 97, 99, 101, 103) for the leads (11, 13, 15, 19, 57, 59, 65, 67, 123, 181).
Claims35
An endoscopic instrument for inserting into a body of a patient, wherein the instrument comprises
- a tubular shank;
- at least two electrical, mechanical and/or optical leads which run through the shank,
- wherein a fluid channel is formed in the shank, the at least two electrical, mechanical and/or optical leads comprising at least two pull wires in a form of flat wires for bending a distal end of the shank;
- and
- a sealing means which forms a proximal end of the fluid channel and comprises feed-throughs for the leads, wherein the sealing means comprises at least two slots as the feed-throughs which pass through a peripheral surface of the sealing means and each slot partly extends through the sealing means, wherein the sealing means has a disc-shaped, round shape, wherein the sealing means is coupled to the shank in a rotationally fixed manner,
- wherein the rotationally fixed coupling is realized by positive-fit means which in the sealing means and in a seal receiver are formed in a manner corresponding to one another.
