Abstract

An instrument for assisting surgical laparascopic or coelioscopic operations where the patient's anterior abdominal wall is formed with an aperture and is raised away from the patient's visceral organs comprises a wirelike body having a first part extending substantially in a plane and adapted to lie against the posterior face of the anterior abdominal wall, a second part extending transversely from the plane of the first part, having an outer end, and adapted to traverse the aperture in the abdominal wall, and a hook at the outer end of the second part adapted to be secured to a stationary support. After inflation of the patient's peritoneum to raise the anterior abdominal wall, the second part of the device is hooked under this wall and the outer end is hooked over a bracket to maintain the abdominal wall raised.
