Patent Application
20190298488
The present invention relates to a dental electronic device for universal application with controlled thrust allowing the positioning of different capsules containing, for example, either a biomaterial or an anesthetic.
There are various types of applicators, manual or electric shaped as a pistol, pen or syringe.
U.S. Pat. Nos. 4,295,828 and 5,306,147 divulge manual applicators in the shape of a pistol and patents FR2535206 and U.S. Pat. No. 4,693,684 divulge applicators in the shape of a pen. Said applicators are, on the one hand, capable of receiving different heads that can be changed depending on the material to be applied and, on the other hand, consist of a mechanical thrust system whose application force is controlled by the practitioner by pressing more or less strongly on the thrust mechanism.
As regards the electric applicators according to U.S. Pat. Nos. 3,395,704 and 6,159,161, it should be noted that the latter generally consist of a thrust device having only one pushing force allowing to apply, for example, only anesthetic liquids.
It should be noted that there are many applicators that can be classified into 3 major categories namely: those in the shape of a pistol, a syringe or a pen.
It should be noted that the applicators in a shape of a pistol or syringe pose ergonomic problems which result in:
The use of applicators in the shape of pistols or syringes causes numerous postural imbalances, namely:
As a consequence, practitioners suffer from a complete panel of musculoskeletal disorders (MSDs):
These disorders appear quickly in the career of the dental surgeon since 70% of them complain of pain in the upper limb after only 3 years of practice.
On the other hand, if we examine a complete care sequence for a dental cavity with all the instrumentation known to date, we notice a series of malfunctions that can be attributed to the use of poor tools.
When a practitioner performs this care protocol, we notice the following malfunctions:
We also note that the economic stakes of profitability of dental practices have become ubiquitous in the practice of dental surgeons.
They continually seek to optimize protocols to save time in all management phases of the practice. The objective is to optimize the work at the chair, improving synchronization with the assistant, and this in a concern for comfort for everyone.
For this purpose, it is therefore very simple, on the one hand, to consolidate in a cassette all the instruments necessary for an operative act and, on the other hand, to consolidate in a tray all consumables needed for the same act.
The cassette and the tray corresponding to the act are placed on the worktops. All the material is found in these 2 containers, allowing the practitioner and the assistant to avoid looking for instruments in the drawers.
However, the current applicators in the form of a pistol or a syringe cannot be integrated into the cassettes because they are too bulky.
Moreover, the multiple systems clutter the cabinets. This has a negative impact on the operation of the organization, both for the practitioner during a treatment and for his assistant during the cleaning of the instruments.
The dental electronic device for universal application with controlled thrust according to the present invention has been optimized to improve both the instrumental care sequence and the intrinsic quality of the treatment.
Also, the dental electronic device design for universal application with controlled thrust according to the present invention has been adapted so that it fits perfectly into the treatment cycle of instruments, which allows optimizing the overall operation of dental offices and significantly increasing profitability.
