Definitions

  • the present invention relates to the surgical setting of fractured bones, particularly to the setting and connecting of the upper part of the femur to the femur shaft, without exposing the bone through a long and wide incision of the overlying tissue and skin by using a technique known as percutaneous connection.
  • a suitably pre-drilled connector plate is positioned and secured by screws to the fractured neck of the femur, and screws are driven through the plate and into holes drilled through the femur shaft and into the femoral head for compressing the bone parts and achieving a quick healing.
  • the invention relates to a surgical device for percutaneous connection of fractured bones comprising both the plate and the added components to remain in the patient's body.
  • EP 0 617 927 Bl discloses a surgical device for percutaneous connection of a fractured upper part of the femur to the femur shaft, according to the preamble of claim 1.
  • the known device provides for a connector plate with two screw-threaded bores for two elongated, partially threaded members or screws to be inserted into the fractured bone, with their outer end portions positioned and movable both axially and rotatably in a sleeve the end of which is adapted for engagement of a screwdriver.
  • a single elongated smooth member partially fitted within a sleeve carrying a portion for the engagement of a screwdriver, the cross-sections of said member and the inner cross- sections of said sleeve being such as to prevent any rotation of the former without requiring additional components.
  • said cross sections are hexagonal and according to another non-limiting embodiment said cross sections provide for a round shape with at least a flat portion such as for example those defined by a circle and a cord, or more generally a polygonal cross section with N sides.
  • the free end portion of the sleeve i.e.
  • the one providing for engagement means of a screwdriver are formed with an inner groove for receiving and holding a plug preventing or limiting the axial displacement of the elongated member.
  • an auxiliary equipment for positioning and securing the connector plate comprising guide means comprising a plug and an inner groove, or guide member, comprising a hollow bolt, and allowing for the insertion of a Kirschner wire used to hold bone fragments in place.
  • the auxiliary equipment can be easily extracted though leaving the Kirschner wire inserted: the hollow bolt is threaded into the inner groove, or guide member, and it can slip on the Kirschner wire upon extraction.
  • a cut is provided in the auxiliary equipment for allowing the axial extraction of the inner groove, or guide member, and a less extended incision is provided too for applying the Kirschner wire.
  • Figure 1 is a front view illustrating a connector plate according to the invention
  • Figure 2 is a cross-section side view of the connector plate of Figure 1 also showing the screws for securing the plate to the bone;
  • Figures 3 and 4 illustrate two embodiments of an elongated member to be inserted into the bone according to the invention
  • Figure 5 is a cross-section side view of an embodiment of a (hexagonal as shown in the side cross section) sleeve according to the invention.
  • Figure 6 is a side view of another (flattened as shown in the side cross section) embodiment of a sleeve according to the invention.

Abstract

L'invention porte sur un dispositif chirurgical pour la connexion de la partie supérieure fracturée du fémur à la tige fémorale, le dispositif coopérant avec un équipement auxiliaire pour une introduction et une connexion du dispositif à l'os fracturé. Le dispositif chirurgical comprend une plaque de connecteur en forme de barre (1) avec une partie de tête (4) pour son introduction à travers une petite incision dans la peau, et comporte au moins deux alésages traversants, fraisés (7). Un alésage taraudé, oblique (5), à un angle de 100° à 140° dirigé dans une direction vers le haut, est formé dans la partie de tête pour recevoir un élément allongé (10) devant être introduit dans la partie d'os fracturé. La partie d'extrémité externe dudit élément allongé est positionnée à l'intérieur d'un manchon (14) et est mobile le long d'une direction axiale, l'extrémité externe dudit manchon (14) fournissant en outre un filetage interne engageant un bouchon (20) pour fermer le manchon (14) et empêcher ou limiter le déplacement axial dudit élément allongé (10). L'extrémité externe dudit manchon (14) comporte en outre un filetage (15) correspondant au filetage dans ledit alésage oblique (5) de la plaque de connecteur (1), et des moyens (16) pour l'engagement d'un tournevis. De préférence, l'élément allongé a une section transversale ayant de 1 à N surfaces planes et correspondant à la surface interne dudit manchon (14), ce par quoi ledit élément allongé (10) ne peut pas tourner à l'intérieur dudit manchon.
