Patent number: 5921972Abstract: A flexible, sterile, trimable device which gently and continuously removes unwanted fluid from an operating field during surgery by wicking the fluid into a mat having a high wicking property. A flexible suction tube having one end embedded in the mat removes fluid from the mat, thereby preventing the mat from becoming saturated. One embodiment of the invention is as a surgical swabber where one end of a length of semi-rigid tube is embedded in the mat and the other end is connected to a flexible suction tube. Another embodiment of the invention is as a platform for microsurgery where a membrane having a plurality of holes is applied to one side of the mat. The membrane supports the tissue being worked on and is preferably a contrasting color. Fluid passing into the holes is wicked into the mat where it is subsequently removed by the suction tube. The platform can be oriented in any position and does not slip on the tissue on which it is placed.Type: GrantFiled: May 13, 1997Date of Patent: July 13, 1999Inventor: Joseph I. Skow
