Said outer sleeve (22) may be removed for po sitioning the surgical instrument (10) at the point of application (10), whe rein the outer sleeve (22) is retracted from the front part (11) of the surg ical instrument (10) by means of a drawing arrangement (21). In particular, the outer sleeve (22) can be drawn backwards over the front part (11) of the surgical instrument (10) and the surgical instrument (10), or the front par t (11) thereof exposed again such that the function of the surgical instrume nt (10) can be carried out unimpeded. The outer sleeve (22) can be returned to the starting position, in particularly by means of a return arrangement. The outer sleeve (22) can preferably be controlled by means of the drawing a rrangement (21) using the handle (15) of the surgical instrument (10).</SDOA B> |
