Abstract
The invention relates to a medical instrument with an elongated shaft (1) and with a handle part (2) that is linked with the proximal end of the shaft (1) and that is used to actuate a tool (4) located on the distal end of the shaft (1). Said shaft (1), in the area of the proximal end, is provided with a seakable flushing connection piece (5). Air and/or a flushing liquid can be guided through said flushing connection piece, especially for the purpose of cleaning, via an adjacent flushing channel (6) up to the stem of the shaft (1). The flushing connection piece (5) is disposed in an acute angle (alpha) with respect to the shaft (1) and faces the proximal end of the shaft (1). The aim of the invention is to provide a medical instrument that is easy to handle and that can be reliably cleaned via the flushing connection piece (5). To this end, the flushing channel (6) is configured as a direct straight and free extension of the flushing connection piece (5) and is also disposed in an acute angle (alpha) with respect to the shaft (1) and faces the proximal end of the shaft (1).
