Definitions

  • the present invention relates to a medical surgery, in particular a dental surgery, with apparatuses and plants in conditions of integrity in order to reduce cross infections drastically.
  • Sterility compliance is the first salient feature of the present invention.
  • Odonto-stomatology from being an almost exclusively technical branch, has currently become prevalently surgical (surgery of the gums, implant surgery, bone grafts, opening and modifying the maxillary sinus, etc.) .
  • this branch of medicine even a simple examination holds dangers, inasmuch as it involves probing the gingival pockets, which always creates microwounds with the escape of blood that may be infected.
  • the stagnant water in the pipes is an ideal terrain for the microorganisms that adhere tenaciously to the inside walls of the pipes.
  • These colonies of bacteria become increasingly better organised as time passes, creating a terrain that is progressively more favourable to the development of the bacteria and it is for this reason that dental units are increasingly responsible for the contamination of dental surgeries as time passes.
  • the material, which is called "biofilm” which lodges inside the supply conduits, in the joints, in the valves and in all the connecting parts is a breeding-ground for entire colonies of bacteria .
  • the object of the present invention is thus to create a medical surgery, in particular a dental surgery, that remedies the aforementioned drawbacks and, more specifically, the object is to create a medical surgery inside which the doctor can work with completely sterile apparatuses that remain completely sterile, patient after patient in order to eliminate cross infections.
  • Another object of the present invention is to create a dental surgery that comprises all the apparatuses that the dentist needs that are distributed in movable trolleys.
  • Impeccable sterility conditions are a fundamental feature so as to eliminate the danger of cross infections .
  • one of the service units contains apparatuses that produce ozone to sterilise the internal and external instruments, which consist of pipes carrying air and water to the rotating instruments and aspiration pipes, and the fittings for fitting the pipes to the service units.
  • the ozone carried to the various installations and to corresponding containers is able to sterilise the instruments and also the entire environment.
  • the reduced volume of the apparatuses and the dental chair that is transformable into an operating table enable the surgery to be used for other medical specialities . This is possible owing to the particular design of the apparatuses and because an environment with integrity sterility has been created, that was until now inconceivable in a dental surgery.

  • a first wall-mounted service unit 160 (figure IA) that is suitable for supplying ozone to decontaminate the piping carrying the water to the apparatuses that supply the rotating instruments, the entire environment and also the instruments .
  • This apparatus 160 after the old dental unit has been divided into different units connected together, is the heart of the system because it is able to sterilise the entire surgery, occupies less space (figure IA) and offers more complete services with greater security for patients and operators .
  • a second base service unit on the doctor side shown schematically in figure IA by 14.
  • This service unit 14 supplies demineralised water that is sterilised by ozone. It also supplies air filtered through absolute filters.
  • the apparatuses within this service unit 14 enable all the piping inside the internal piping of the trolley of the doctor and of the assistant to be sterilised by means of heavily ozonised water.
  • a third base service unit on the assistant side shown schematically in figure IH by 122, for collecting and disinfecting sludge collected from the surgical aspirator and from the washbasins, and for evacuating the sludge into the drains.
  • a trolley 11 (figure IA) on the doctor side that carries the rotating instruments. This trolley 11 is supplied by an (umbilical) cord that leads away from the service unit 14. 5) A trolley 12 on the assistant side (figure IA) , operationally connected to the service unit 122, that carries the water/aspiration unit and a series of drawers that contain overgloves and other sterile material that is ready for the assistant to use.

  • the instruments have to be sterilised for conservation, the instruments have to be bagged and when the instruments exit the rotating cylinders 164 and 165 the bags are sealed.
  • the ozone must be humidified so that it has a greater effect, it is thus passed through the humidifiers 171 before entering the rotating cylinders through the quick-release fitting 176.

In this manner, everything is easily sterilisable for each patient and at a few centimetres from the saliva ejector in the mouth of the patient or from the surgical cannula working on a wound there are no pipes that remain for years and are encrusted with saliva, blood, tooth filings and metals, as occurs in most of the apparatuses that have been used until now.
  • the forks 163 that place the aspirating pipes 164 (figure 16c) by means of the connections 1617 are fixed on the right side of the column.
  • SA saliva ejector
  • IM funnel/spittoon tray
  • CH surgical cannula
  • the internal part of the column of the assistant is sterilised by drawing the 3 aspirating pipes in a container filled with ozonised water. By activating the aspiration of the 3 pipes, the disinfectant will pass through the internal pipes, the solenoid valves, and the filter and will be discharged into the drains.
  • the rear part of the column is closed and the filter and the solenoid valves are accessed only by lifting the top 161.
  • the column 12 of the assistant acts also as a servo unit.
  • the drawer 1621 contains a box containing in turn overgloves . These boxes and the contents thereof have been sterilised by gamma rays.
  • the overgloves are worn overgloves when the dentist or the assistant of the dentist are obliged to open cabinets to take instruments or medicines with gloves that are soiled with blood and saliva. After the task with the overgloves has been performed, the overgloves are removed and disposed of and the doctor can continue to work on the mouth without contaminating that which surrounds him, the doctor.
  • the other boxes contain sterile paper towels and currently used instruments and medicines. All this will be clearer by studying the protocol .
  • the water/aspirating column 12 rests on a base with wheels .
  • the third service trolley 13 located on the doctor side is actually a servo unit in the form of a column with a shape that is identical to that of the column 12 of the assistant (figures 17A, 17B and 17C) .
  • This column 13 has six drawers that contain the same things that have been disclosed in the drawers of the assistant. The top is used as a resting surface.
  • the dental chair/couch 125 of the surgery has interesting ergonomic features, the first of all of which is that of not having corners, zones retaining dust, concertina pipes (as are provided, on the other hand, in the prior art) or other parts that are not easily reachable for cleaning and disinfection.
  • the dental chair/medical -surgical couch has been completely redesigned, to set as an objective the production costs for something that is currently missing on the market.
  • the basic feature of this dental chair is that the dental chair can be transformed into an operating table and, consequently the surgery can be exploited for nearly all medical specialities.
  • An arm can be added to the sides to support a table of a theatre nurse or a support arm for the intravenous drip.
  • the dental chair/couch disclosed in the present invention is extremely ergonomic, but with an infinity of possible positions (figure 20) and the possibility of extending vertically by approximately 30 cm (from 45 to 75 cm) .
  • the rectangular metal base 1812 (figure 18B) rests on the floor (figure 20), has reduced dimensions and inserts 4 wheels (figures 18C and 18D) . This is possible with the addition of 2 bars 1813, which are fixed below the base 1812 by means of the screws 1811. These wheels have brakes that ensure stability for the dental chair.
  • the dental chair comprises a frame divided into three parts
  • the seat 191 has another hinge 199 that enables (Trendelenburg) movement with the fulcrum in 199.
  • Two parallelpipedons 1910 which slide on one another in the ascent and descent movement and two motors, one on the right and one on the left under the seat 191, enables all the dental chair/couch to be moved until it is able to be transformed into an operating table.
  • the electric power supply is provided by a cable coming from the channel that descends from the corner of the room on the assistant side (127, figure IA) .
  • Two motors located at the base determine the ascent and descent movement (reference 1910, figure 19) and, in turn, the aforesaid motors are controlled by the actuation of the pushbuttons of the switch panel on the console of the column of the doctor (figure 11) .
  • the motors are covered by two parallelpipedons 1910 that each follow the lifting and the descent of the horizontal plane of the dental chair by sliding on one another.
  • the motor of the foot column determines the Trendelenburg position (figure 20) by making a fulcrum on the hinge 199.
  • the motor of the foot column determines the Trendelenburg position (figure 20) by making a fulcrum on the hinge 199.
  • At the central part of the seat there are two motors, one on the right part and another on the left part.
  • One of these motors determines the ascent and the descent of the back of the chair (figure 20) and the other the ascent and the descent of the footrest part, which may reach almost 90° by removing the footrest 185 (figure 18A) and 207 (figure 20) .
  • the rounded conformation of all portions of the dental chair determines an advantage in terms of general cleanliness of the furnishing and complete sterilisation of the environment of the dental surgery, also by virtue of the possibility of movement by means of the wheels.
  • Position "0" (zeroing), completely high back of the chair, seat horizontally completely low, enables the patient to be approached easily who has to sit on or descend from the dental chair, or rinse his mouth.
  • the preselected position "1" is a standard position in odonto-stomology that can be modified with the movement of the back of the chair to take the position "1" to a position of optimal comfort for the patient and which is ergonomically more suitable for the operator.
  • the preselected position "2" positions everything horizontally at maximum height to have a medical couch/surgical operating table (see figures 20 and 19) .
  • a medical couch/surgical operating table see figures 20 and 19.
  • One matter that has not been discussed is the safety of the dental chair/couch. Large movements had to be protected to ensure completely the safety of the hands of the patient, but also the legs of the operator and of the assistants.
  • the metal skirts 1911 that cover the motors positioned on the sides of the seat have another metal part inside that protrudes by about 1 centimetre and runs upwards in the event of even a minimal contact . This reascent determines an electric contact that arrests all movement. The same safety is ensured on the sides of the back of the chair and on the footrest part (1912, 1913) .
  • the zones corresponding to the hinges 194 and 195 have safety spaces for the hands .
  • This headrest can replace the headboard 185 of figure 18A.
  • loudspeakers 1816 that protrude from the sides of the headrest. They are not in contact with the ears, whilst allowing only the patient to listen to music perfectly, with almost zero diffusion into the environment. There are no cables that reach the loudspeakers inasmuch as there is an infrared emitter positioned on the ceiling.
  • the present invention in the various components thereof, represents a single unit that complies with the concept of sterility in the dental surgery, a concept that is repeated by an infinite number of scientific works throughout the world and which no person has until now solved comprehensively.
  • the entire operating unit thus combines everything that the dentist needs and the operating unit that is thus conceived is also eminently suitable for the work of doctors of other specialities.
  • the entire assembly is part of the present invention, as they are components that overall replace together the previous use of dental units, by placing the dental units in conditions of integrity in order to reduce drastically the hazard of cross infections during dental treatment.

Abstract

La présente invention concerne la chirurgie médicale, et plus particulièrement la chirurgie dentaire, impliquant de nouveaux appareils comprenant tous les instruments nécessaires au dentiste. Il peut s'agir de chariots mobiles pouvant être déplacés de sorte que le travail soit aussi ergonomique que possible. L'intérieur de l'un desdits chariots contient toutes les sources d'énergie nécessaires au maniement des instruments à utiliser. Lesdits instruments possèdent des accessoires à déclenchement rapide situés sur les conduits d'alimentation, de manière que la partie de ceux-ci avec laquelle le dentiste est en contact est stérile pour chaque patient et pour le dentiste. Ladite chirurgie comprend au moins un appareil (160) adapté à l'alimentation en ozone (O3), afin de stériliser les appareils transportant les instruments en rotation, les aspirateurs d'eau, l'environnement dans son ensemble et tous les instruments. Le dentiste peut donc travailler avec des appareils et dans un environnement, entièrement stériles, et ceux-ci restent stériles au fil du temps, patient après patient, ce qui permet d'éliminer les risques d'infections croisées.
