Abstract
A medical instrument arrangement includes an operation microscope system (100) and a carrier unit (101) carrying the operation microscope (102). The medical instrument arrangement is at least partially covered by a drape (110). The air inside the drape (110) is removed by a suction unit. The drape (110) is fixed to a portion of the carrier unit (101) at a collar (115). By operating the suction unit at different suction rates, disturbing vibrations of the system during a surgical procedure can be minimized.

A medical instrument arrangement for use in a surgical procedure carried out on a patient under sterile conditions, the medical instrument arrangement comprising:
- a surgical instrument for use by a surgeon during the surgical procedure;
- a carrier unit for supporting said surgical instrument;
- said surgical instrument having surfaces which are unsterilized;
- said carrier having a mounting structure thereon defining a barrier disposed between the unsterilized surgical instrument and the ambient;
- said mounting structure defining a smooth surface extending over the periphery thereof;
- a gastight sterile drape completely enclosing the unsterilized surfaces of said surgical instrument;
- and,
- an attachment device for attaching said drape to said mounting structure at said smooth surface thereof so as to provide a gastight interface between said drape and said smooth surface thereby preventing an infection of the patient from said unsterilized surfaces during the surgical procedure.
