- the inventive step relates to a principle of manufacturing an instrument or tool for curettage, absorption, sanitization.
- the general characteristic of which describes a rod or rod made of plastic with axial symmetry, having at the same time a multidirectional controlled flexibility, elasticity and flexibility to ensure efficiency, good grip and good support of instrument or tool. These flexibility and elasticity will be determined according to the desired effects when the components forming the mother material of the rod are included.
- the profile of the rod rod in its transverse and longitudinal form will accept a geometric figure (for example of section: round, square, octagonal, ovoid ).
- a predetermined profile of convexity or concavity of the rod of the rod will preferably be given at the time of its manufacture.
- the rod rod can be hollowed out or provided with a medullary canal which serves as a reservoir for a substance or to convey a fluid or liquid.
- the end of the rod rod will have in its median axis a cavity which will lead to a notch whose length and width will vary significantly from the defined model.
- the notch and cavity will serve as a receptacle and secure clasp.
- the sides of the notch must perfectly fit the part which comes to be included in the cavity by contiguous edges to leave no room for any roughness.
- the edges of the end of the rod rod in the direction of the cross section will be flat and free on half the circumference.
- the other half of the circumference will have an integral part in the shape of a bulb with a slightly rounded dome which, for medical reasons may tend towards an ovoid or almond or even pear dome ....
- the whole bulb will be made up of several flexible and elastic bands supporting a torsion-rotation.
- the bulb will be divided into two parts in the longitudinal direction and held together by a clip serving as a hinge.
- the part of the bulb not secured to the rod rod will have at its base an axis of shape and dimensions identical or even similar to the cavity of the clasp of the rod rod. Indeed, the part of the bulb which is not integral with the rod rod will fold back and snap or snap into the cavity and the notch-clasp of said rod rod thus forming the complete instrument which is the subject of the present invention.
- the bulb of the curettage instrument according to the method of manufacture and embodiment of the. mold.
- Sier- ⁇ .fo raâ.-d-.U ⁇ .ae --tjaQa ⁇ L.ej ⁇ ..plastic material by flexible and elastic strips or bands supporting a torsion-bending coniuge according to an overall helical or semi-helical movement.
- the part of the instrument or hand tool called the bulb or head of the stick will be manufactured according to different models.
- the bulb can be designed by a plurality of strips or strips whose central core will be hollowed out.
- the part of the hollowed-out bulb will be filled with a plastic material having similar characteristics, either of being more flexible, or firmer, as well as of a more or less pronounced porosity.
- the bulb will be designed by flexible plastic bands and the inside forming the core by a natural fiber (cotton), or an artificial fiber (viscose), or a nonwoven
- the bulb may be composed of strips or strips of nonwoven with a core of natural fiber or of artificial, synthetic fiber.
- the strips or lamellae of the bulb, or only the dome, or the assembly may, at the time of their manufacture, integrate structural drawings or patterns, for example: (teeth, spikes, striations ).
- the rod rod will receive ergonomic grips in order to facilitate the introduction and possibly the rotation.
- the rod of the stick according to the invention can carry two opposite and slightly curved parts which can take the form of a fingerprint.
- a color code may be provided, for example: (the red stick + white bulb) or even (white stick + green bulb).
- the application of the color can be done entirely on the part to be treated, by a ring system, by an alphabetical inscription, by a digital or alphanumeric inscription.
- the bulb according to the invention can be supplied at the factory pre-impregnated with a liquid or pasty substance. In order not to suffer a loss of product by drying or drying, it will be ensured that the bulb or the head of said stick is covered with an impermeable film provided for this purpose. I! It is obvious to a person skilled in the art that for technical reasons which are specific to him, it is possible to cover the entire instrument with a specific film.
- the filming of the hand tool will be recommended to make it sterile or when its emoloi is done under a sterile environment. In order to facilitate the packaging of such hand tools, they will be connected to each other by means of their protective envelope at their ends, to form a chain and be placed in a dispenser box.
