Definitions

  • This application generally relates to surgical retractors.
  • a surgeon may utilize a retractor to separate tissue at the edges of a wound or surgical incision and provide access to underlying organs and/or tissue.
  • Various means for providing illumination of the revealed tissues have been used. For example, in many surgeries, illumination may be achieved using overhead mounted lights or a head mounted light system. However, among other problems with these approaches, the surgeon’s body or other objects may sometimes block illumination light preventing adequate lighting of the surgical site.
  • some handheld retractors may include a fiber optic light conduit integrated within the retractor’s handle.
  • An inlet end of the conduit may include a connector for receiving light from an external source so that an obstructing power or fiber optic cable may be required in or around the working space of the surgery.
  • An outlet end of the light conduit may be positioned for direct illumination at the surgical site.
  • such retractors are not compatible for use with retractor assemblies including a frame.
  • At least some handheld retractors may include plastic optical fibers and may be disposable. While generally appropriate for disposable applications due to there generally low cost, commonly used plastic fiber optical components are not compatible with routine sterilization protocols. Moreover, reliance on disposable plastic fiber optics may compromise the quality of light provided for illumination.
  • Some illumination systems may make use of one or more dedicated light modules attached directly to the frame.
  • the use of such light modules necessarily takes up space on the frame. Extra time may also be used to set up and adjust these dedicated light modules.
  • modem day surgeries may sometimes make use of a plurality of different attachments so that the use of additional frame attachments specifically dedicated to illumination may not always be desirable.
  • some retractors or other frame mounted attachments may require positioning at particular locations on the frame. For this reason and other reasons, dedicated illumination modules may not always be placed in an ideal position for optimal or uniform illumination of a surgical site.
  • a retractor configured for illuminating a surgical site which may be used with a surgical retractor assembly comprising a frame including those frames with a capability for supporting multiple attachments and allowing for adjustment in the position of the retractor blades.
  • a retractor would allow for both retraction of tissue at the edge of a surgical incision or wound opening and also provide for illumination of a surgical opening formed when expanding the incision or wound opening.
  • Such a dual equipped retractor may allow for improved management of limited space around the surgical retractor frame and improve the speed at which emergency operations may be performed.
  • It would also be beneficial to configure a retractor and light conduit which may be subjected to multiple sterilization cycles, and which may be comprised of high numerical aperture light accepting glass fiber optics.

As shown in Fig. 6, the blade 40 bends towards the inner face 27 at bend 77. Notably, if positioned too far down the blade 40 and past the bend 77, the distal end 76 of distal end portion 48 may be disposed too deep within a cavity formed by the incision 26.
  • the light emitting portion 48 of light conduit 28 may seat within the spacer or mount 32 so that the innermost edge of the portion 48 is held at a generally fixed distance X2 from the outer face 54.
  • the distance X2 may be about 0.20 cm to about 0.50 cm.

Abstract

Un écarteur chirurgical peut être conçu pour être monté sur un cadre d'écarteur chirurgical auto-retenu. L'écarteur chirurgical peut comprendre une double capacité pour à la fois rétracter un tissu au niveau d'une plaie ou d'un site d'incision chirurgicale et pour fournir un éclairage de site chirurgical. L'écarteur chirurgical peut comprendre un conduit de lumière, un montant de montage et une lame. Le conduit de lumière peut être disposé le long d'au moins une partie de la lame à une certaine distance pour définir un espace de décalage entre le conduit de lumière et le montant. En opération, le montant peut être reçu en translation à l'intérieur d'une ouverture formée dans le raccord de telle sorte que le raccord est déplacé à l'intérieur de l'espace de décalage et la lame est déplacée dans une direction appropriée pour la rétraction de tissu.
