Abstract
Description
- This application is a continuation of U.S. patent application Ser. No. 15/631,069 filed Jun. 23, 2017, entitled “ORGAN RETRACTION DEVICE,” which claims priority to U.S. Provisional Patent Application No. 62/471,405 filed on Mar. 15, 2017, entitled “ORGAN RETRACTION DEVICE,” each of which is incorporated herein by reference in its entirety.
- The field of the present invention and its embodiments relate to an organ laparoscopic retraction device, namely a liver retraction device. In particular, the embodiments describe an organ retractor that forms a “sling” to position the organ during laparoscopic surgery.
- Laparoscopic surgery, also called minimally invasive surgery, bandaid surgery, or keyhole surgery, is a modern surgical technique in which operations are performed through small incisions, usually 0.5-1.5 cm, located on the body of the patient.
- There are a number of advantages for a patient who undergoes laparoscopic surgery rather than a traditional “open” procedure. Patient pain and hemorrhaging are reduced due to the smaller incisions utilized in laparoscopic type surgeries and recovery times are thus shorter.
- Notwithstanding the above, minimally invasive surgery is still in its infancy. Throughout the past two decades numerous devices have been developed to enable safer and faster procedures, including anastomosis creating devices, energy sources, and superior surgical site imaging.
- However, there are also a number of shortcomings of laparoscopic surgeries including but not limited to, a limited range of motion at the surgical site for the surgeon resulting in a loss of dexterity, poor depth perception as it relates to the surgical site, an inability to accurately judge how much force is being applied to tissue, and a lack of desired results as opposed to when the patient and surgical area can be opened up.
- Additionally, retraction capabilities have been put aside and currently, organ laparoscopic retraction is based on standard laparoscopic tools. The evolution of laparoscopic surgery lends itself towards an era of minimizing the number of ports and shrinking the port size even further.
- Thus, there is a need for an organ laparoscopic retractor, preferably for a liver, that may be inserted/removed through the port and positioned in the cavity throughout the procedure. The present invention and its embodiments meets and exceeds these objectives.
- Various systems and methodologies are known in the art. However, their structure and means of operation are substantially different from the present disclosure. The other inventions fail to solve all the problems taught by the present disclosure. At least one embodiment of this invention is presented in the drawings below and will be described in more detail herein.
- Generally, the present invention and its embodiments provide for an organ retractor, namely a liver retractor, for use in laparoscopic surgeries. However, the device described herein may be suitable for any organ and any number of organs.
- Preferably, the device is intended to support the liver or other organ(s) in a “hammock” type structure. A sling is formed from a suitable mesh fabric. Coupled to the mesh may be a curved needle and a straight needle. The curved needle may be attached to the diaphragm (or other suitable structure) of the patient during use and the straight needle (Keith needle) may be placed through the abdominal wall. The Keith or other suitable needle may further be anchored in position via a hemostat. The liver, being supported, by the sling will be positioned such that there is an optimal exposure of the operative field.
- The sling may further be reinforced along some portion or along the entire periphery of the sling. This added rigidity allows the sling to gently cradle the liver while yet having the resiliency to properly retract the liver. The attachment points, of the suture(s) to the sling, may further be reinforced to prevent tearing during manipulation of the sling before, during, and/or after use.
- In one embodiment of the present invention there is a medical device comprising: a sling; a first needle coupled to a first end of the sling, wherein the first needle is coupled via a first suture having one point of attachment on the sling; and a second needle coupled to a second end of the sling, wherein the second needle is coupled via a second suture having two points of attachment on the sling.
- In another embodiment of the present invention there is a medical device comprising: a triangular sling having a reinforcement material disposed along a periphery of the sling; a curved needle coupled to the sling, via a first suture, at a first attachment point at a first end of the sling, a straight needle coupled to the sling, via a second suture, at a second attachment point and a third attachment point at a second end of the sling.
- In yet another embodiment of the present invention there is a medical device comprising: a triangular, polymer sling having a silicone reinforcement material disposed along a periphery of the triangular, polymer sling, wherein the silicone reinforcement material is disposed between at least two layers of the triangular, polymer sling; a curved needle coupled to the triangular, polymer sling, via a first suture, at a first reinforced attachment point at a first end of the triangular, polymer sling; and a straight needle coupled to the triangular, polymer sling, via a second suture, at a second reinforced attachment point and a third reinforced attachment point at a second end of the triangular, polymer sling; wherein each of the first reinforced attachment point, the second reinforced attachment point, and the third reinforced attachment point are separate vertices of the triangular, polymer sling.
- In general, the embodiments of the present invention succeed in conferring the following, and others not mentioned, benefits and objectives.
- It is an object of the present application to provide an organ retractor that is capable of supporting a liver or other organ.
- It is an object of the present application to provide an organ retractor that can be passed through a trocar during a laparoscopic procedure.
