Electrical cutting device for laparoscopic removal of tissue from the abdominal cavity.
The extraction of large tissue masses from the abdominal cavity during laparoscopic surgery is a time-consuming, complicated process. A new prototype instrument is introduced that allows quick laparoscopic removal of fibromas, ovaries, or other tissues from the abdomen. A cylinder with a coning knife at its intra-abdominal end is placed inside the trocar sleeve and is rotated by an electrical micro-engine attached to the trocar. Cylindrical tissue blocks are cut step by step out of the main specimen and removed from the peritoneal cavity through the sleeve with a grasping forceps. Tissue removed is suitable for histologic examination. The principal application is morcellation of fibromas, whereas use in ovarian disease is limited. This new device provides a safe and effective approach inside the abdominal cavity.
