Definitions
- the present invention relates to a duct instrument sleeve of a new type.
- the object of the present invention is to propose a new type of handle which presents the main advantages of the two types of handle of the state of the art without presenting the disadvantages of one or the other, and which solves the problem. of the handle of the document D 1 .
- the invention which consists of a root canal instrument sleeve of the rotary endodontic type, for example a cutter tail, comprising at its end intended to engage in a drive assembly of a workpiece head. hand or a contra-angle, an annular groove and a flat to cooperate with complementary means of axial connection and rotational connection provided in the drive assembly, characterized in that it is made of two coaxial parts including an inner portion and an outer sleeve covering the inner portion on at least a portion of its length, means being provided to secure the sleeve on the inner part in both axial translation and rotation, and in that it comprises means for locking in rotation and in translation to cooperate with a canal instrument and characterized in that the rotational locking means consist of protrusions of the sleeve each having a lateral edge placed in the plane of a flat part parallel to the axis of the handle and provided at its end intended to engage in a drive assembly .
- the invention also relates to an assembly (channel-instrument-canalaire), characterized in that the handle is of the above type, and characterized in that the canal instrument has an axial recess (1a) made on the instrument by deformation or removal of material.
- the canal instrument has an axial recess (1a) made on the instrument by deformation or removal of material.
- FIG. 1 general view of a handle according to the invention according to a first variant embodiment
- FIG. 3 general view of a handle according to the invention according to a second embodiment
- FIG. 4 longitudinal sectional view of the handle of Figure 3
- FIG. 8 sectional view of another embodiment of non-circular section.
- the principle of a handle according to the invention is to be produced in two coaxial parts, for example cylindrical, of which an inner part (3) and an outer sleeve (2) covering the internal part over at least part of its length, means being provided for securing the sleeve (2) on the inner part (3) in both axial translation and rotation.
- the internal diameter of the sleeve is equal to the outer diameter of the inner portion (3), over the length of cover.
- the section of the handle is not necessarily cylindrical, one can consider for example a polygonal section, or as in the example of Figure 8 an interface section between sleeve (2) and inner portion (3) of polygonal shape.
- the handle according to the invention is mounted on an instrument or a blade (1) passing through from one side.
- the handle is mounted on an instrument or a blade (1) embedded in the inner portion (3).
- the sleeve (2) can be made for example but not limited to metal, it can be colored or uncolored.
- the inner part (3) can be made for example but not limited to plastic material.
- the sleeve covers the inner part (3) in a central zone, over a predetermined length and is locked axially by shoulders (3a) and (3b) provided at the ends of the inner part (3) or by any locking means equivalent translation.
- Rotational locking means are also provided and may be constituted for example, but not limited to, by projections (2a, 2b) each having a lateral edge (2c) or (2d) placed in the plane of a flat (3c ) parallel to the axis of the handle and provided at its end for engaging in a drive assembly. This same end also has an annular groove (3d).
- the annular groove (3d) and the flat (3c) may preferably be in accordance with the ISO 1797 nome of the dental instruments so as to be able to engage the handle in the heads of handpieces and counter angle complying with this standard.
- Means are further provided to join in translation and rotation the inner part (3) to the blade (1).
- Means are further provided to join in translation and rotation the inner part (3) to the blade (1).
- the blade (1) of the canal instrument an axial recess (1a), made either by removal of material, or by deformation (for example a simple crush) of said blade.
- the material of the inner part at the time of molding fill said recess.
- ends of the inner part (3) are made of plastic materials of different types and / or colors, and that the shapes of the shoulders (3a, 3b) are different.
