Abstract

The invention relates to a device for cutting out and removing cylinders of tissue from a tissue, which is located inside a body or joint cavity and / or in or on a wall region thereof, comprising a cutting device (12) with a hollow-cylindrical base body (14), a distal opening (18) on a distal end (16) of the base body (14), and a cutting element (20) surrounding the distal opening (18), further anactuating device (22) for rotating the base body (14) about the longitudinal axis (24) thereof on a proximal end (26), and / or on a region (28) facing the proximal end (26), of the base body (14), anda sealing device (30) for closing and opening a proximal opening (32) on the proximal end (26) of the body (14), and the use thereof.

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. However, such devices have proven to be significantly disadvantageous in practice. Such devices are used, for example, in the field of gynecology 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. A drawback of all such devices is generally their structural design. Such devices generally have a relatively complex and relatively uncompact and u...
