Wire guides and anchors for endoscopy
View Patent ↗A wire guide system is provided for use during a endoscopic surgical procedures. The wire guide system includes a cylindrical shaft having a hollow chamber along a longitudinal axis of the cylindrical shaft, a flange fit disposed around the cylindrical shaft and a seal disposed around the cylindrical shaft and abutting the flange. The system may also include an anchor affixed to the cylindrical shaft and having an aperture from which at least one of a sensor, a light, a camera, tissue and/or organs may be suspended therefrom and at least one cable extending from one end of the cylindrical shaft to another end of the cylindrical shaft through the hollow chamber.
1. A wire guide system comprising:
a cannula having a hollow chamber along a longitudinal axis, the cannula having an outer surface and inner surface defining a wall of the cannula; a flange disposed around the cannula; a seal disposed around the cannula and abutting the flange; an anchor affixed to the cannula and having an aperture; a first electrical connector attached about a distal end of the cannula; a second electrical connector attached about a proximal end of the cannula; a first conduit within the wall of the cannula, the first conduit extends between the first electrical connector and second electrical connector; a device mounted within the aperture of the anchor; and a second conduit coupling the device to the first conduit via the first electrical connector.
2. The wire guide system according to claim 1 , wherein the seal includes:
an adhesive disposed on a surface of the seal; and
a removable cover disposed over the adhesive.
3. The wire guide system according to claim 2 further including a cap.
4. The wire guide system according to claim 3 , wherein the cap is a silicone valve.
5. The wire guide system according to claim 1 , wherein the distal end of the cannula is tapered.
6. The wire guide system according to claim 1 , wherein the anchor is attached to the cannula via an interference fit, a snap fit, a bayonet coupling, a latch coupling, or a magnetic coupling.
7. The wire guide system according to claim 1 , wherein the anchor is configured to be manipulated around at least one axis.
8. The wire guide system according to claim 1 , wherein the device is a sensor, a light, or a camera.
