DARTS: Dundee Anchored Retraction and Tether System
Surgical retraction for Single Port Laparoscopic Surgery poses a problem which is currently resolved by an additional port (i.e. an extra abdominal wound) for insertion of a laparoscopic retractor. This clearly compromises the original intent of the approach which aims to execute the operation through a single umbilical incision thereby reducing scarring and postoperative pain from multiple abdominal wounds. A new retraction system is proposed in which the target tissue is retracted by tethering it to the abdominal wall.
This system consists of
- a latching clamp which grasps the tissue,
- a holding piece resting on the abdominal wall which has a fine, long atraumatic needle used to pierce the abdominal wall and
- a tether linking the latch to the external holding piece.
Such a system provides excellent exposure, is easy to deploy and can be inserted at any site, singly, or in multiples if more than one site of retraction is needed for surgical exposure. A development programme is proposed in which prototype devices will be designed and systematically evaluated in animal tissue and human cadavers. The complete device will be licensed to a collaborating company.
