Abstract
An instrument is described for the penetration of body tissue with a hollow shaft, the point of which is formed as a conical, beveled, or tapered window. An optic with a lighting unit is brought into the point through the hollow shaft. The optic ends at an axial distance behind the summit of the point. The instrument can be inserted within view. In so doing, the entry of the point can observed over the entire surface area thereof. Preferably, a second optic is run to the summit of the point, which in addition enables improved observation of the area lying directly in front of the point.
