  • FIG. 1 illustrates an embodiment of a prior art guide conduit 10 capable of being manipulated in the one-handed fashion, as described in United States Patent Application Publication US 2007/0055204 Al.
  • the guide conduit 10 is formed of a first member 2 cooperatively associated with a second member 4.
  • the first member includes an elongated portion 6 joined to a delivery arm portion 8 by a bend region 10 defining a desired angle.

  • the second member may include a protrusion 25 cooperable with the depression in the first member for defining the channel that receives the catheter.
  • tongue 26 and groove 28 members formed on the first and second members respectively hold the first and second members together.
  • the tongue and groove members may have their respective positions reversed as to the first and second members.
  • the tongue and groove members are illustrated as having generally rectangular cross-sections, although other shapes may be used in other embodiments.
  • a bottom side surface 30 of the second member is placed against a topside surface 32 of the first member with the two members at a position where the tongue and groove members do not interface.
  • the two members are then slid relative to each other with the second member moving toward the distal end of the first member to bring the respective tongue and groove members into sliding engagement to join the first and second members together.
  • first and second members include three mating sets of tongue and groove members, although in other embodiments a different number of sets may be used. Any other known geometry of sliding engagement mechanisms may be used between the first and second members to provide a connection between the first and second members when they are in one relative position, and to provide a disconnection when the first and second members are slid relative to each other to a second disengaged position.

  • the first stop member is formed to be integral with the tongue member closest to the distal end 36 of the device, although in other embodiments the stop member may be formed separately.
  • the stop member cooperates with a second stop member 38 on the second member, which in this embodiment is the groove member closest to the distal end, to limit the extent of movement of the second member toward the distal end of the first member.
  • the interference between the stop members limits movement of the second member toward the distal end of the first member when the members are engaged, thereby preventing the delivery arm portion of the second member from pinching closed the depression in the distal end of the first member when the second member is slid onto the first member, thus ensuring free passage of a catheter there through.
  • the first and second members may then be separated to release an enclosed catheter by pulling the finger rest with the index finger to slide the second member relative to the first member which is being held stationary by the palm and thumb.
  • the optional thumb rest having a relatively flat area for contacting the thumb is useful for keeping the device from rotating within the palm as pressure is applied against the finger rest by the index finger.
  • the second member is released from the first member after being slid beyond the engaged length of the tongue and groove members, which is within the range of motion of the index finger.
  • an engaged length of the tongue and groove members may be limited to be no more than a distance of movement of the second member caused by the pulling motion imparted by the index finger while a person holds the guide conduit by the handle.
  • Guide conduit 50 includes a first member 52 cooperatively associated with a second member 54 which are illustrated in FIG. 2 in an assembled configuration.
  • the first member includes an elongated portion 56 joined to a delivery arm portion 58 by a bend region 60 defining a desired angle.

  • the elongated portion and delivery arm portion include a depression (not shown) suitable for receiving and guiding a catheter (also not shown) to a surgical site as described in United States Patent Application Publication US 2007/0055204 Al.
  • tongue members 76 (hidden in FIGs. 2 and 3 but visible in FIGs. 4 and 5) and groove 78 members formed on the first and second members respectively hold the first and second members together, as described above.
  • tongue and groove members may have their respective positions reversed as to the first and second members.
  • the tongue and groove members are illustrated as having generally rectangular cross-sections, although other shapes may be used in other embodiments.
  • the embodiment of FIGs. 2-5 includes three mating sets of tongue and groove members, although in other embodiments a different number of sets may be used. Other geometries of sliding joints between the first and second members may also be envisioned.
  • An engaged length of the tongue and groove members is illustrated as distance d in FIG. 2 and is defined as the linear distance of relative movement between the first and second members in the direction of the elongated portion longitudinal axis L over which the tongue and groove member remained engaged to prevent relative separation of the first and second members in a direction perpendicular to axis L.
  • the engaged length of the tongue and groove members determines how far the finger rest 80 must be moved relative to the handle 62 in order to disengage the tongue and groove attachment to allow disassembly of the guide conduit 50.
  • the engaged length depends upon the lengths of the tongue members 76 and groove members 78 and upon the location of any stop 74 that may limit full engagement there between.
  • the present inventor has discovered that it is advantageous for a surgeon to hold the handle of the guide conduit 50 with one hand during a surgical procedure, such as right hand 100 as shown in FIGs. 3-5, while using the other hand, such as left hand 102, to disengage the first and second members from each other.
  • a surgical procedure such as right hand 100 as shown in FIGs. 3-5
  • the other hand such as left hand 102
  • the present inventor has innovatively sized the engaged length d of guide conduit 50, and further has specially positioned and sized the thumb rest 58 and finger rest 80 of guide conduit 50.
  • the engaged length d is less than a distance D between a proximal surface 82 of the finger rest 80 and a proximal surface 84 of the thumb rest 58 along an axis L parallel to longitudinal axes of the respective elongated sections when the guide conduit 50 is in an engaged configuration, hi this manner, a surgeon or other person holding the handle 56 with one hand 100, as shown in FIG. 3, can pinch the thumb rest 58 and finger rest 80 together between his/her index finger 104 and thumb 106 of the other hand, as shown in FIG. 4, to disengage the tongue and groove members 76, 78 and to separate the second member 54 from the first member 52, as shown in FIG. 5 and for the purpose described in United States Patent 7,195,614.
  • Control of the apparatus is enhanced during the sliding action when compared to prior art devices because the thumb 106 is maintained in contact with the thumb rest 58 during the entire sliding movement necessary to disengage the tongue and groove members 76, 78, and because finger 104 tends to urge the second member 54 downward against the first member 52 during the sliding operation while the first member 52 is being held securely by hand 100.
  • the finger 104 and thumb 106 come together to firmly pinch the finger rest 80, as illustrated in FIG. 4, the second member 54 can be moved upward and away from the first member 52, as illustrated in FIG. 5, without disturbing the placement of the first member 52 or the associated catheter (not shown) from its position in the surgical wound.
  • the present invention provides a geometry for improved control of a guide conduit device 59 during a surgical procedure with resultant accurate placement of a catheter.

Abstract

L'invention porte sur un conduit de guidage (50) pour positionner un cathéter pour l'administration d'une analgésie à un site cible durant une opération chirurgicale. Un appui-pouce (58) sur un premier élément (52) coopère avec un appui-doigt (80) sur un second élément (54) du conduit de guidage pour permettre au chirurgien d'activer un désengagement coulissant d'éléments de languette (76) et de rainure (78) pour permettre au conduit de guidage d'être retiré du site chirurgical sans déloger le cathéter. La longueur engagée coulissante D est inférieure à une distance D entre une surface proximale (82) de l'appui-doigt et une surface proximale (84) de l'appui-pouce le long d'un axe longitudinal L lorsque le conduit de guidage est dans une configuration engagée de telle sorte que le chirurgien peut pincer l'appui-pouce et l'appui-doigt ensemble entre l'index (104) et le pouce (106) pour désengager les éléments de languette et de rainure.
