Enclosure module design thesis for Endoblend : a novel surgical device for laparoscopic hysterectomy

The Endoblend device concept was developed by a 2.75 design team,of which I was a member; the purpose of the device is to remove tissue laparoscopically. The detailed design of one of its modules, the enclosure module, is the subject of this paper. The Endoblend has the potential to reduce morcellation surgery time from upwards of half an hour to minutes, with reduced risk of the most common complications of nicking the abdomen wall and leaving tissue behind. There are three primary functional requirements of the enclosure module. First, for ease of use, simplicity, and safety the bag and guard in combination must passively feed the tissue into the blades. This was accomplished using, a cone shape to make the bottom of the bag act as an equilibrium state through a gravity feed. Second, the bag must remain intact to prevent tissue from being left behind. To accomplish this it will be shaped with a flat region near the blades so that inflating the bag keeps it away from the blades, and the Ziploc type seal through which the tissue enters will be a double seal with micro beads of cyanocrolate to make a strong permanent seal.
