Apparatus for securing one or more suction tubes, hoses, and electrical and/or endoscopic cables during an operation. The apparatus is a surgical attachment device that includes a slightly flexible member (flexible plastic, for example) having one or more grooves formed therein. A first portion or tunnel of each groove is dimensioned to slidably secure the respective tube, hose, or cable. A second portion of each groove, superficial to the first portion, is slightly narrower than the first portion of each groove. This configuration allows for insertion of the tube, hose, or cable into the tunnels, which is done by transiently deforming the narrower portion of the groove, deforming the tube, hose, or cable, or both, and pushing the tube, hose, or cable into the tunnel. A second embodiment of the apparatus include selected additional lower grooves separated from the grooves by hinge areas that permit easy flexing of the flexible member and opening of the grooves to permit insertion of the tubes, hose, or cables. Once the tube, hose, or cable is within its tunnel, the narrower portion of the groove restricts unintended pull-out of the tube, hose, or cable from the attachment device. The length of the tunnels and the relative dimensions of the tube/hose/cable to their tunnels determines the drag coefficient as they are pulled through the tunnels. These proportions are designed to provide for intentional sliding through the tunnels, and also provide sufficient friction to resist most unwanted motion. Each groove may be flared at their ends. In the case of the suction tube, this flaring allows the tube to undergo angular movement without compromising the internal geometry of the tube. An adhesive layer is disposed on the second surface of the flexible member so that it may be secured during an operation.
