The utility model has the advantages of simple structure, convenient operation and safety, the utility model can be used for multiple selected preparation and caries filling protection, the damage of the existing mouth cavity clinical apparatuses to the mucous membrane of the mouth cavity and the soft tissue injury can be effectively prevented, and the limitation that the existing protective device is only provided with single protection is broken through.
Description
This utility model belongs to medical apparatus and instruments, and what relate generally to is a kind of tooth preparation protector, and it is worn that its adaptation is used for polishing, cutting, the tooth body slit of tooth preparation, the safeguard procedures of dental caries preparation.
At present, the dentistry clinician is when doing tooth preparation both at home and abroad, generally be to rely on mouth mirror to pull bicker, in oral artificial tooth is repaired, class devices such as employed drill bit, bladed sandstone sheet, emery wheel all need place in the oral cavity and rotate, because rotating speed is very fast, in operation if interior mucosa of careless slightly rapid wear wound and soft tissue.Though also have the protector of monotype to sell (shown in figure four) in the market, it is mainly injection molded by resin material, because it belongs to the monotype preventer, can only be used to do the preparation of sandstone sheet tooth uses, and bad mechanical property, not wear-resisting, certain limitation is arranged during use.
The purpose of this utility model promptly produces thus, proposes a kind of tooth preparation protector, and this protector can prevent apparatus lesion ports transmucosal and soft tissue effectively in the reparation of clinical oral artificial tooth.
For achieving the above object, this utility model is realized by following technical scheme: it is made of protective cover, protective frame and adnexa, protective cover is the butterfly type, its rear portion is designed to matrix, its both sides are designed to complete symmetrical structure, its bottom is a concave-curve, is respectively arranged with forward and backward two groups of fixing holes on the camber endpoint location of concave arc, can be used with protective frame, adnexa respectively by the fixing hole protective cover.
Protective frame is made up of forearm, the arm of force, time arm of force and screw rod, wherein forearm, the arm of force, four arm of forces are left and right symmetric two, the protective frame front portion forms circular arc type after by two forearm symmetries, be sharp tooth before it, fixedly connected with the arm of force respectively in its rear end, two rear ends of the arm of force are an integral body, it is provided with and is used to circular hole that screw rod is passed, junction at the forearm and the arm of force also is connected with back simultaneously the arm of force, the other end of this time arm of force is fixed on the forward position of screw rod jointly, and the circular hole that the setting of arm of force rear end is passed at the screw rod rear portion connects by fixed by nut; Adnexa is made up of preceding adnexa and rear attachment, and its bending two ends is used for being connected with the fixing hole of protective cover, and position, intermediate portion and teeth patterning coincide.
This utility model reasonable in design, because of protective cover and protective frame and adnexa thereof all adopt stainless steel metal material or plastic production, so it has mechanical performance preferably, and safe and reliable, no chemical stimulation, be convenient to sterilization, and have anticorrosion, durable characteristics.Because this protector is placed on the tooth body in use, thereby prevented the damage of medical apparatus and instruments effectively to oral mucosa and soft tissue, and highly versatile can be made multinomial selection preparation (large, medium and small emery wheel, sand sheet can be optional when preparation) and cavity and fill protective action.
This utility model has following accompanying drawing:
Accompanying drawing 1 is this utility model structural representation.
Accompanying drawing 2 is the protective cover expanded view.
Accompanying drawing 3 is the protective frame structural representation.
Accompanying drawing 4 is the accessory structure sketch map.
Accompanying drawing 5 is existing protector structural representation.
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in the figure: this utility model is by protective cover, protective frame and adnexa constitute, it can adopt metal material or plastic to make, protective cover 2 is butterfly type (as shown in Figure 2), its rear portion is designed to matrix 1, its both sides are designed to complete symmetrical structure, the bottom of both sides is a concave-curve 4, group fixing hole 3 and back group fixing hole 5 before on the camber end points position of concave-curve 4, being respectively arranged with, can be respectively and protective frame by preceding group of fixing hole 3 and back group fixing hole 5 protective covers, the supporting use of adnexa, the two side ends afterbody of protective cover 2 can extend back, extending part is provided with and is used at ordinary times adnexa being articulated it, can be convenient to protective cover is carried out disinfection and hanging of time spent not.Protective frame is formed (as shown in Figure 3) by forearm 9, the arm of force 10, time arm of force 13 and screw rod 11.Wherein: forearm 9, the arm of force 10, time arm of force 13 are respectively left and right symmetric two, the front end 8 of forearm 9 is sharp tooth, purpose be convenient to protective cover 2 on establish cover fixing hole 3 be connected, forearm 9 is camber, it is round that its symmetry back forms arc, purpose is that it is connected with protective cover 2 when using, and is convenient to the apparatus flexible operating when tooth preparation.Rear end at forearm 9 is connected with the arm of force 10 respectively, the arm of force 10 symmetries, and its rear portion is an one, it is provided with and is used to circular hole that screw rod 11 is passed, forearm 9 and 10 movable connections of the arm of force.But also global formation.Junction at the forearm 9 and the arm of force 10 also is fixedly connected with back the arm of force 13 respectively by retention pin 14, returning the arm of force 13 its other ends of symmetry back all is fixed on the forward position of screw rod 11 by retention pin 14, the circular hole that the arm of force 10 rear portions are provided with is passed at the rear portion of screw rod 11, and is fixedly connected by nut 12.Adnexa is formed (as shown in Figure 4) by identical preceding adnexa 15 and rear attachment 16 respectively, and it can adopt the rustless steel steel wire to make, and its bending two ends is used for being connected with fixing hole 3,5 on the protective cover 2, and position, intermediate portion and teeth patterning are identical.
When this utility model uses, its protective cover 2 and the supporting use of protective frame, the pointed tooth 8 of protective frame forearm 9 front ends is inserted respectively in the prelocalization hole 3 that is provided with on the protective cover 2, the locating hole 5 at rear portion is fixing with the bail head 7 that is arranged on the forearm 9 on the protective cover 2, after protective cover and protective frame connect as one, concrete position according to tooth preparation, protector is sent into the oral cavity, the forearm front end is after fixed point on the tooth body, clockwise direction reverses the nut at screw rod rear portion, make the card arm point of its front end be fixed on the cheek-tongue side of tooth body, its protective cover is then on the plane, the incense patient prepares use, after tooth preparation is intact, counterclockwise reverse the nut at screw rod rear portion, make the loosening tooth body that breaks away from of card arm point.When protective cover is used in combination with adnexa, adnexa 15 is penetrated in the locating hole that is provided with on the protective cover, adnexa 16 can be selected to penetrate in the back locating hole of protective cover as required, adnexa is placed bite plane, the protective action in the time of can playing tooth preparation.
