摘要：
An instrument system for minimally invasive surgery in the tissue of a patient, with an instrument shaft, having a distal end that can be inserted in the body of the patient and a proximal end that remains outside the body, with an inner channel extending axially and continuously in the instrument shaft, with at least one working channel extending axially and continuously in the instrument shaft, and with an obturator which can accommodate an optical system coaxially and can be inserted into the inner channel in such a manner that its transparent distal tip projects out from the beveled distal front end of the instrument shaft. The system can include a valve block at the proximal end of the instrument shaft, closing the inner channel and enabling sealed passage of the obturator or an optical system.
