Definitions
- Blocking plug of an element in a groove Blocking plug of an element in a groove.
- the invention relates to a threaded plug blocking an element in the bottom of a groove made in the threaded part of an organ and more particularly of rods or connecting plates relative to the head of an organ such as 'a vertebral implant or hook in the spinal shoring devices.
- the invention solves the problem of creating a threaded plug blocking a rod or a cable in the bottom of a groove made in a threaded part of a member, with which , on the one hand, a large tightening torque can be applied without risk of bending of the walls delimiting the groove and, on the other hand, a serious hooking on a rod, a plate or a cable is obtained, so that a joining effective, which can only be canceled by voluntary action on the nut using a key designed for this purpose.
- the threaded plug blocking an element in the bottom of a groove made in a threaded part of a member, according to the invention is mainly characterized in that it comprises, in its middle, a guide finger and d cylindrical spreading, at its base, regularly distributed asperities and, at its upper part, a means for driving in rotation.
- the guide and spreading finger consists of a cylinder with a diameter corresponding to the width of the groove or the location provided for receiving it.
- the rotary drive means can be constituted an impression made in the axis of the guide and spreading finger.
- the rotary drive means consists of cylindrical orifices drilled in the head of the plug regularly distributed in a circle concentric with the axis of the plug.
- the rotational drive means consists of an imprint made in the axis of the spreading finger and cylindrical orifices drilled in the head of the plug in a circle concentric with the axis of the plug.
- the cylindrical orifices of the rotary drive means are each located in the median plane of one of the sides of said polygonal imprint.
- the impression made in the axis of the guide and spreading finger is polygonal, the latter can be provided with a thread produced in the sides of said impression.
- the tool for driving in rotation the threaded locking plug is characterized in that it consists of a key, with a base having, in its center, a finger, of the same section as the cavity of the threaded plug, around which are apartis, on a circumference coaxial with the finger, drive pins fitting into the corresponding holes drilled in the head of the threaded plug.
- the threaded blocking plug according to the invention and its drive tool mainly applies to the fixing of spreading rods or connecting plates on vertebral implants used in spinal surgery.
- FIG. 1 represents a front view, in partial longitudinal section, of a screw implant secured to a knurled rod for connection by the intermedia 2 of a threaded plug.
- - Figure 2 shows a top view in section, along the plane AA of the assembly shown in Figure 1.
- FIG. 3 shows a partial front view of the operating key of the threaded plug, shown in phantom as well as the implant head on which it is screwed.
- FIG. 4 shows a bottom view of the threaded plug.
- FIG. 5 represents a front view, in longitudinal section, of the threaded plug.
- FIG. 6 shows a top view of the threaded plug.
- the figures show a threaded plug 10 for locking a rod 20, knurling 21, in the bottom of the groove 32 of the head 31 of a screw implant 30; said threaded plug 10 comprising, in its axis, a guide and spreading finger
- the contiguous notches 12, produced at the base of the threaded plug 10 are designed so as to materialize radial teeth 121 of a shape favoring sliding during tightening and engagement in the knurling of the rod during loosening.
- the height of the guide and spreading finger 11 is a little less than the depth of the threaded plug 10, so that its end does not come into contact with the rod; said etan end ; provided with a wide chamfer 111 of alpha angle, of a value of 45 °, to facilitate the introduction of the guide and spreading finger 11 in the groove of the head of the threaded implant.
- the polygonal imprint 13 is hexagonal and the cylindrical orifices 14 are six in number, each located in the median plane of a section of the hexagonal imprint 13.
- a thread 131 can be produced in the polygonal imprint 13, in order to facilitate the handling of the plug 10 and its presentation on the head of the screw implant, before tightening using the key.
- the application of the threaded plug 10 according to the invention is not limited to the attachment of a rod to a screw implant, since other assemblies using a grooved threaded part can be produced by this means, under reserve of minor adaptations, not departing from the scope of the invention.
