Medical instrument and method for producing same

Abstract

The present invention relates to a medical instrument (1), comprising a tool (10), a catheter assembly and a handle (20), by means of which the tool (10) can be actuated, and to a method for producing the medical instrument. The tool (10) is a wire construction having at least two wire portions (11′, 11″, 12′, 12″, 13′, 13″) and is arranged at a distal end of the catheter assembly. The catheter assembly is formed from an outer tube (3) and an inner tube (4), which is arranged coaxially to the outer tube. Furthermore, the medical instrument (1) has an optical waveguide (2), which extends through the inner tube (4) and the exit end (2′) of which opens into a space delimited by the tool (10). At least one first wire portion (11′, 12′, 13′) is fastened, at a proximal end (11a, 12a, 13a) thereof, to the distal end of the inner tube (4), and at least one second wire portion (11″, 12″, 13″) is fastened, at a proximal end (11b, 12b, 13b) thereof, to the distal end of the outer tube (3). The outer tube (3) and the inner tube (4) are movable relative to one another, and the tool (10) can be actuated for opening and closing by means of the relative movement between the outer tube (3) and the inner tube (4). The medical instrument (1) does not have a guide wire for actuating the tool (10).
