A morcellator (1) for morcellating tissue within a body cavity of a patient is provided in combination with first (17) and second (18) tissue-pulling devices, and an insert (19). The morcellator (1) comprises a handle portion (2) having a lumen (6) passing therethrough, and an aperture (10) communicating with the proximal end of the lumen. A tube (3) extends from the handle portion and has a tissue cutting device (7) located at the distal end of the tube. The handle includes first (11) and second (12) valves associated with the lumen of the handle portion, and the first and second tissue-pulling devices have shafts of a first diameter and second diameter respectively. The insert (19) comprises a stem (21) and a body portion (20), the stem being received in the aperture (10) to form a substantially gas-tight seal in combination with the first valve (11). The body portion (20) remains outside the aperture and includes a third valve (22), the third valve (22) being such that is forms a substantially gas-tight seal around the shaft of the second tissue pulling device (18) when the second tissue pulling device is inserted into the lumen of the insert. |
