General information
1.1 Indications Morcellator set for morcellation and extraction of tissue and for removing myomas or the uterus during laparoscopic procedures in surgery and gynaecology.
1.2 Principle The ERGO 300 - Morcellator is a control unit for the BOWA Morcellator for use in morcellation and extraction of tissue. A rotating cylindrical tube with a blade at the distal end is inserted through an abdominal cavity that has been enlarged by an Insufflator. The tissue that is to be removed is guided to the cutting tube by a gripper, cut off and removed through the tube. This manual describes three different options for removing tissue by a laparoscopic procedure. Option 1: Tissue removal by morcellation with protective tube. Instruments (gripper) are inserted through a protective tube sealed by a valve system. The valve can be covered by a thumb for removing the gripper from the sealed protective tube to prevent gas loss. Option 2: Tissue removal by morcellation with Trocar Cannula. Instruments (cutter tube, gripper) are inserted through the Trocar Cannula. The Trocar Cannula contains a valve that prevents gas loss when withdrawing the instruments. Option 3: Tissue removal (myectomy) with myoma drill through the Trocar Cannula. The myoma drill is inserted through the Morcellator (protective tube or Trocar Cannula). The Trocar Cannula and the protective tube can be used with or without a cutting tube. No gas loss after removal of instruments with the Trocar Cannula, minimum gas loss during removal from the protective tube, sealing unit can be sealed with the thumb.
1.3 Contraindications Do not use the Morcellator for the following: •
Treatment of malignant tumors
•
Treatment of vascularized tissue
•
Preparation of tissue
1.4 Medical application This product is designed solely for use in medical facilities by medically qualified persons.
