| 摘要 |
<p>The invention relates to a medical instrument (10) comprising a shaft (12) and a detachably fixed tool (18) which is arranged on the distal end of the shaft (12). Said shaft comprises an inner shaft (14) and a tubular shaft (16) which surrounds the inner shaft and which can move in a longitudinal manner in relation thereto. The tool (18) is locked on the shaft (12) when the tubular shaft (16) is in a forward-staggered locking position in relation to the inner shaft (14), and can be detached from the shaft (12) when the tubular shaft is in a backward-staggered release position in relation to the inner shaft (14). The aim of the invention is to facilitate the handling of the instrument when changing the tool. In order to achieve this, said instrument (10) comprises an activating element (40) which can move essentially perpendicularly in relation to the longitudinal direction of the tubular shaft (16). The activating element interacts with the tubular shaft (16) in such a way that the tubular shaft (16) is moved from the locking position into the release position by means of the activating element (40) moving from a first position to a second position and vice versa.</p> |
