Instrument for the penetration of body tissue with cutting and viewing of body structure |
摘要 |
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 to the point through the hollow shaft. The optic ends at an axial distance behind the summit of the point. An advancing element having a cutting edge extends along the point. The instrument can be inserted while viewing the structure to be penetrated. In so doing, the structure adjacent the point can be observed over substantially 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.
