Abstract

This invention relates to a device (20) for inserting and positioning surgical instruments (10) in the body of a patient, with an outer cover (22), into which outer cover (22) at least a front part (11) of the surgical instrument (10) is insertable, and which outer cover (22) is removable for positioning the surgical instrument (10) at the point of application, the outer cover (22) being pulled away from the front part (11) of the surgical instrument (10) by means of a pulling device (21). In particular, the outer cover (22) is able to be pulled backwards over the front part (21) <sic. (11)> of the surgical instrument (10), and the surgical instrument (10), or respectively its front part, is able to be uncovered again, so that the function assigned to the surgical instrument (10) is able to be carried out unimpeded. The outer cover (22) can be returned to the starting position, in particular also by means of a return device. The outer cover (22) is preferably able to be controlled by means of the pulling device (21) using the handle (15) of the surgical instrument (10).

Claims

1-17. -17. (canceled)

18. A device for inserting and positioning surgical instruments in the body of a patient, with an outer cover, into which outer cover at least a front part of the surgical instrument is insertable, and which outer cover is removable at the point of application for positioning the surgical instrument, wherein

an opening is able to be created at the tip of the outer cover by means of a pulling device and/or perforations, and
