Abstract

The invention relates to an apparatus for cutting out and removing tissue cylinders from a tissue located within a cavity of the body or a joint and / or in or on a wall section thereof. Said apparatuscomprises at least two, especially two cutting devices (12, 12'), each of which has a hollow cylindrical base (14, 14'), a distal opening (18, 18') at a distal end (16, 16') of the base (14, 14'), anda cutting element (20, 20') that surrounds the distal opening (18, 18'). The at least two cutting devices (12, 12') are disposed inside each other and can be rotated relative to one another. The apparatus further comprises at least one driving device (22) for rotating the respective base (14, 14') of the at least two cutting devices (12, 12') about the longitudinal axis (24, 24') of the base (14,14'). The invention also relates to the use of said apparatus.

Description

technical field [0001] The present invention relates to a device for cutting and removing a cylindrical mass of tissue from tissue located inside a body cavity or a joint fossa and / or in or on the wall region thereof. Background technique [0002] Such devices are generally known. Accordingly, such a device is used, for example in the field of gynecological medicine, for removing tissue from the uterus, removing the entire uterus or for treating fibroids, etc., using both a trocar and a trocar sleeve. Such a device is known, for example, from EP 0 522 125 B1. Devices of this type are also used in the medical field in numerous and to some extent different other specialties, for example in abdominal surgery, on gastric surgery and for cholecystectomy or cecal resection. In practice, however, this arrangement has proven to be somewhat disadvantageous. Such devices therefore generally have only one cutting device with a hollow cylindrical base body, a distal opening at the di...
