Device for gently removing tissue from animal or human tissue

Device for dilating and restoring the lacrimal duct in the human eye

A biopsy system includes a biopsy gun and a biopsy needle, the latter of which has an inner needle, also called a mandrel, and an outer tube, also called a cannula. The mandrel has a recess in the vicinity of its distal end which receives the tissue sample to be collected and has a first collecting element at its proximal end for connection with a slide of the biopsy gun. The cannula also has a connecting element at its proximal end for connection with another slide of the biopsy gun. The connecting elements each have an opening into which a pin provided on each of the respective slides can be inserted. In addition, at least one slide has a rib that extends in the lengthwise direction of the biopsy needle, the rib engaging a corresponding connecting element.

Biopsy needle

A device for taking tissue samples by means of a biopsy cannula comprising a needle element with a cavity in its distal terminal zone and an exterior tube surround the needle element, which cannula is inserted into the tissue to be sampled by means of an inserting unit. The inserting unit causes the needle element and the exterior tube to move together into a position inside the tissue in which the exterior tube is pushed over the cavity, the inserting unit retracts the exterior tube behind the cavity in the needle element after termination of the inserting operation, and subsequently pushes the exterior tube again over the needle element so as to cover the cavity.
