[0022] FIG. 2 shows an instrument of dental and medical insertion according to a preferred embodiment of the present invention;

[0023] FIG. 3 shows the cut-off view of a dental and medical insertion instrument according to a preferred embodiment of the present invention; and

[0024] FIG. 4 illustrates a dental and medical insertion tool comprising a dental and medical insertion instrument according to a preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0025] Regarding, FIGS. 1 and 2, present invention describes an instrument of medical/dental insertion, the instrument comprising: an axle 1; a fixing region 2; and an insertion element 4; where the fixing region 2 makes the connection of the insertion element 4 and the axle 1; the axle 1 rotating the insertion element 4 when connected; where the fixing region 2 comprises a magnet 3 configured to fix the insertion element 4 on axle 1.

[0026] According to a preferred embodiment, the fixing region 2 comprises at least one hole 3′ in a position perpendicular to axle 1, wherein the magnet 3 is inserted into hole 3′ in order to fix the insertion element 4 on axle 1, and magnet 3 is preferably manufactured in samarium, cobalt or neodymium, and may comprise an external layer of humidity-resistant protection, as shown in the cut-view of FIG. 3.

[0027] Preferably, the insertion element 4 is configured to connect to a medical/dental device, where shaft 1 is manufactured in Stainless Steel according to ASTM F-899, the length of the dental and medical insertion instrument varies between 16 mm and 250 mm, and the 3′ hole for magnet fitting 3 comprises a width between 2.0 mm and 8.0 mm.

[0028] Still in reference to the FIG. 3, the 3′ hole can receive a cover 6 on both sides, which prevents the magnet from being exposed to the environment or humidity at the time of autoclaving, preventing the magnet from being corroded.

[0029] The cover 6 can be made of resin or polymers, so as to seal the hole 3′ with the magnet inside, being ideal for autoclave sterilization processes.

[0030] The present invention also describes a tool 5 of dental and medical insertion, comprising an instrument of dental and medical insertion according to the above defined, in which tool 5 is of the type against angle and/or ratchet, as shown in FIG. 4.

[0031] Given the description above, one of the advantages of the present invention is to eliminate the natural wear that occurs in retention, mechanical type, between tools, while also facilitating the handling of instruments.

Device Operation

[0032] The axle 1 is tightly fitted to the tool 5, as shown in FIG. 4. Thus, when the torque is applied by the professional in tool 5, the same torque is applied to axis 1, which in turn transmits the torque to the insert 4, which finally transmits the torque to the implant or prosthesis screw.

[0033] Due to the fact the insertion element 3 is fixed, by magnetic force of the magnet 3 present in the hole 3′ of the fixation region 2 of the axis 1, this region has little wear compared to the traditional fitting, in which relative movement between the pieces in the fixing region causes small collisions that over time increases the wear of parts in that region.

[0034] Another advantage is the durability of its components, which are exposed multiple times to processes such as autoclave.

[0035] Having described an example of a preferred embodiment of the present invention, it should be understood that the scope of the present invention covers other possible variations of the inventive concept described, being limited only by the content of the claims, including the possible equivalents.
