Abstract
A method of passing suture through a pledget is disclosed. A first suture tail is passed through a first suture engaging loop extending out of a first aperture in the pledget on a distal side of the pledget. A second suture tail is passed through a second suture engaging loop extending out of a second aperture in the pledget on the distal side of the pledget. The first and second suture tails are drawn proximally through their respective pledget apertures by pulling a handle coupled to the first and second suture engaging loops on a proximal side of the pledget.
Description
- None
- This invention relates generally to surgical suturing and more particularly to a device for remotely placing a surgical pledget at a suturing site and drawing suture tails through the pledget to be secured proximally of the pledget.
- The general medical definition of a pledget is a small compress, tuft, or flat mass usually made of gauze or absorbent cotton that is laid over a wound or into a cavity to apply medication, exclude air, retain dressings or absorb discharged matter. The pledget concept, in a more specifically surgical application, often applies to material or bolster used to help reduce the risk of suture pulling through tissue that it is holding by cushioning and spreading the load of the suture against the underlying tissue. Surgical pledgets have been used throughout history and remain a routinely utilized adjunct to suture mediated tissue repair even in the most advanced modern surgical procedures.
- In addition to pledgets distributing the retaining force of the suture over a larger area of tissue, they can aid in minimizing the leakage of bodily fluids, such as blood, that results from penetration of bodily tissue by a suture needle and suture. Pledgets may be left implanted permanently at a wound closure site or a prosthetic attachment site. If indicated, they can also be subsequently removed along with the sutures from the patient.
- A pledget may be placed completely under a section of suture or it can be configured so that the suture passes through one or more sections of the substance or the body of the pledget itself. A pledget also may be placed before or after the suture has been passed through tissue. By passing the suture through the pledget, the suture and the pledget can be more conveniently and securely handled during the suture placement process. While a pledget could be placed under the suture and above the tissue without the suture traversing through the pledget, this is often not practical or reliable under certain surgical conditions, especially those involving the remote suturing as are needed in many minimally invasive surgical procedures.
- Furthermore, a pledget not threaded with a suture is more readily dislodged during manipulation or by movement or change of shape (e.g., swelling resolution) of the tissue.
- Pledget Description. Pledgets are usually small pieces of thin, relatively soft material intended to atraumatically distribute the suture compressional forces over a broad area. They are conventionally formed from biocompatible flexible materials such as foam, felt or fabric. Pledgets are often made from non-resorbable polyurethane, polyamide, polyethylene, polypropylene, polyethylene terephthalate, polytetrafluoroethylene (PTFE or Teflon®), or various absorbable polymers, such as polyglycolic acid or even pieces of autologous tissue. These materials are selected based on surgical judgment to offer sufficiently enhanced structural integrity to assure that after the suture is tied, the pledget is held securely but gently against the tissue surrounding the suture to prevent tearing of the suture through the tissue and to reduce or prevent bleeding at suture puncture wounds. Common pledgets are conventionally formed from flat cloth-like material and are usually configured in circular, oval or rectangular shapes. Pledgets can be supplied as loose individual pieces with or without preformed suture holes extending through full thickness of the pledget, with preformed specialized suture entrance slits to accommodate alternative methods of placement with suture as described for example in U.S. Pat. No. 4,823,794 or as sets of multiple connected pledgets as described, for example, in U.S. Pat. No. 5,733,308) or pre-loaded on sutures with needles (e.g., Gore-Tex TH-22 {Flagstaff, Ariz.} or Covidien 3336-51 {Mansfield, Mass.}). Pledgets not preloaded on suture are also commercially available (e.g., Ethicon PCP20 {Somerville, N.J.}, TFE Polymer Pledgets (Firm)) with or without pre-formed holes through the body of the pledget just large enough to accommodate a suture of the desired size.
- Suturing with Pledgets. Pledgets are usually used when more than one tissue bite is performed with one suture. A single loop suture, called a simple interrupted suture, does not typically require a pledget since a single loop going through two edges of a wound would have only a pledget on top of the wound. When more than one tissue bite is required, it is more practical to use pledgets under the sections of suture not passing through the tissue. For example, a so-called double armed suture with a needle at each end and with a pledget on the suture between the needles can be used to provide a pledget located on top of the tissue between the tissue entrance holes of the needles at the side opposite from where the knot will be placed (Reed and Cortez, “Measured Tricuspid Annuloplasty: A Rapid and Reproducible Technique”, Annals of Thoracic Surgery, Vol. 21, February, 1976, pp. 168-169.) After the needles have exited the tissue site, by passing these two needles through a second pledget, this second pledget is located on the knot side of the closure on the top of the tissue between the needle exit sites. For conventional hand-tied knots, both needles would typically then be cut off from the suture and the hand-tied knotting process would commence over the second pledget near the needles exit site. Tightening the suture draws the two pledgets together and holds the tissue in compression.
- Alternative Suturing and Knotting Techniques. Alternative techniques of suture placement, especially those used with mechanically assisted suturing devices, often provide two suture ends left untied on one side of the wound closure site or a prosthetic attachment site (U.S. Pat. Nos. 6,997,931; 7,731,727; U.S. application Ser. No. 12/835,464). For automated mechanical knots, it would further be helpful to not only pass the suture through the pledget but to continue to pass the same suture ends through the mechanical knot. The use of a single loop wire snare to pull suture ends through a mechanical knot (U.S. Pat. Nos. 5,520,702; 5,643,289; 5,669,917; 6,368,334; 6,641,592; 7,235,086) is currently commercially available through the Titanium Knot® Quick Load® unit and the Cor-Knot™ Quick Load® unit for the TK and CK device products, respectively, from our company, LSI SOLUTIONS®, Victor, N.Y. This single loop suture snare approach is easily and quickly learned by surgeons; it has been successfully employed to help secure suture in thousands of patients throughout this country.
- The use of pledgets with surgical suturing confers many compelling advantages, but placement of a pledget on the suture ends at the knot side of the suture still presents inconvenient challenges and unnecessary risks. A pledget preloaded onto a suture, either through the use of needles or passing suture ends through pre-placed holes in the pledget, provides more definitive capture of the pledget.
- Prior to this invention, the requisite use of needles to pass suture through pledgets would require several extra steps, increase the risk of needle injury and infection, and may not prove possible in many modern surgical interventions. While reducing the risk to the surgical team of unnecessary needle exposure is critical, the advantages of pledgets for the patient should not be sacrificed because of the difficulties of hand threading the suture through the pledgets. Hand threading suture ends through tiny holes in pledgets is not practical and may not even be achievable in the diminished ambient light conditions of many video intensive operating rooms. Custom slotted pledgets can offer some benefits, but may not satisfy the requirements for ease-of-use, effectiveness and safety in minimally invasive surgery applications, especially those involving automated suturing or automated knot placement technologies. The currently marketed single loop wire snare devices now available for pulling suture through mechanical knots do not aid in the placement of suture through pledgets. Devices to reduce the dexterity requirements and complexity of modern surgical operations can decrease anesthesia and surgery durations and potentially improve patient outcomes. A surgeon should have the option for the expedited use of enhancements, like pledgets, based on clinical needs without concerns regarding reliability or excessive time expenditures. The present invention addresses these needs.
