The present invention generally relates to a device and method of use for closure guides. More specifically, the present invention generally relates to a device and method of use for a visually assisted single-site port closure guide.
Without limiting the scope of the disclosed device, the background is described in connection with a novel device and method of use for a visually assisted single-site port closure guide.
Today many surgeries are performed within a patient's body with the assistance of elongated tools and cameras. The patient's abdomen is inflated and must stay inflated to allow access and visualization inside the abdominal cavity. Small five to fifteen millimeter defects are created around the cavity to allow access inside of the patient's body. In order to maintain inflation of the cavity or pneumo as well as accessibility, these sites must have a trocar placed inside the defect. A trocar is a direct access port with a hollow lumen and pressurized seals to maintain air pressure. They are purely designed to keep the defect open and to provide direct access. Trocars to not provide any role with the closing of the defect.
When a procedure is completed, the trocar is pulled out of the defect and a closure device is placed inside the existing defect. When the trocar is placed inside of the abdomen, all layers of the abdominal wall were punctured. If a defect is ten millimeters or larger as a rule of thumb, the fascial layer at the bottom must be sutured to in order to prevent herniation through the port sites following the procedure. To close these defects, surgeons use laparoscopic port site closure devices. It is possible to hand suture but the defect is extremely small and the fascial layer is near the deepest point which makes it extremely difficult to be accurate. Closing a port site involves using a suture passer, a sharp needle-like post with jaws at the end to hold a suture, inside the patient to pass suture from one side of the defect to the other in order to bring the edges of the fascial layer together. Having a sharp inside of the patient's body requires optimal pneumo and direct camera visualization. Current methods and approaches involve placing a camera in an adjacent port to allow visualization of the closure.
While all of the aforementioned devices and approaches may fulfill their unique purposes, none of them fulfill the need for a practical, effective, and efficient means for a closure guide.
Therefore, the present invention proposes a novel device and method of use for a visually assisted single-site port closure guide to address the shortcomings in the prior art.
The present invention, therefore, provides for a closure guides. More specifically, the present invention generally relates to a device and method of use for a visually assisted single-site port closure guide.
In an embodiment, the closure guide device is comprised of a main body element having a cone portion, a bulb portion, a center vertical cannula portion, and two angled channel portions. The cone portion is cylindrical in shape. In embodiments, the cone portion is tapered from top to bottom. The bulb portion is positioned at the tip or end of the cone portion and is clear. In embodiments, the bulb portion is made of a clear polymer or glass. The center vertical cannula portion is positioned through the longitudinal axis of the of the cone portion being open at the top and terminating at the bottom of the cone portion at the bulb portion. The two angled channel portions are for receiving and passing through a suture passer or sharp. In other embodiments, the main body element is further comprised of a cap portion. In yet other embodiments, the main body element is further comprised of left and right wing portions.
In summary, the present invention discloses a novel device and method of use for a visually assisted single-site port closure guide.
