Abstract
The present application discloses a medical instrument for tissue ablation by a minimally invasive surgical procedure, including a hollow outer shaft, an inner shaft which can be guided longitudinally displaceably in the hollow outer shaft, and a control portion at a proximal end of the medical instrument, in order to position the hollow outer shaft. An attachment for mechanical ablation of tissue is arranged at a distal end of the inner shaft, wherein the attachment does not protrude beyond an inner profile formed by the inner faces of the outer shaft, and wherein at any rate the distal end of the attachment protrudes beyond the distal end of the hollow outer shaft in order to ablate tissue. The medical instrument may be combined with further medical appliances, in particular with an HF coagulation attachment or a laser coagulation attachment for tissue coagulation.
