Abstract
The invention relates to the technical field of oral medicine, in particular to a fold edge type dental floss blade, which comprises a guide master slice, a bolt, a cutting edge notch, a handle, a blade, a blade hole, a guide sub slice, a bolt hole and a guide groove. The external outline of the guide master slice is elliptic, the linear guide groove is arranged on the edge of the guide master slice, the edge of the guide groove and the external edge of the guide master slice are in arc transition, the external outline of the guide sub slice and the external outline of the upper half of the guide master slice are mutual mirroring shapes, the guide groove and the major axis of the ellipse of the guide master slice form an included angle of 45 degrees, and the inner end of the guide groove is provided with the cutting edge notch which is right angular and fold line shaped. The fold edge type dental floss blade avoids the larger damage vertical drawing force which is generated when a traditional dental floss pick is pulled out, and accordingly, the damage to the joint of the tooth root and the alveolar bone is avoided.
Description
Technical field
The present invention relates to the stomatology technology field, particularly relate to a kind of sword formula dental floss blade that turns.
Background technology
Existing dental floss stick, normally consisted of by exceptionally straight polyester fiber dental floss by a segmental support and one, first dental floss is pressed into (referring to Fig. 6 of Figure of description) in teeth space during use, and then moves around in teeth space, tartar is taken out of, then dental floss is extracted from teeth space.Existing those skilled in the art are known as, and using dental floss stick to reject tartar is a kind of mode of operation of health, because dental floss is soft, can not damage tooth.But this viewpoint is wrong, and it be the reasons are as follows:
1. the shape of corona has up big and down small feature usually, and this just makes the teeth space between adjacent two teeth have up-small and down-big feature (referring to Fig. 7 of Figure of description).Therefore can obviously feel when using dental floss stick, relatively require great effort in the process that dental floss is pressed into teeth space, in case but dental floss is when entering into teeth space near the position of gingiva, mobile dental floss is just obviously much laborsaving, and the process that dental floss is extracted from teeth space is again relatively required great effort.
2. the masticatory function of tooth has determined that tooth has the stronger ability of bearing vertical pressure, but a little less than the up big and down small structure of root of the tooth makes the ability relative thin of tooth bearing tension.
In view of above-mentioned 2 points, be therefore that dental floss has applied larger pulling force to tooth at the process nature that dental floss is extracted from teeth space, teeth space is narrower, and pulling force is larger, and is also just larger to the infringement of root of the tooth.The existing dental floss stick of life-time service applies pulling force to tooth repeatedly, can significantly cut down the adhesion between root of the tooth and alveolar bone, causes the loosening of root of the tooth, and therefore many patients feel that the teeth space tooth of more picking one's teeth is more loosening.This is to need for many years to solve but not only not solved by those skilled in the art always, but also the technical problem of not recognized by those skilled in the art.
Summary of the invention
The present invention is for solving the deficiencies in the prior art, provide a kind of after using dental floss stick to reject tartar, the dental floss of can be safely, first will stretch into easily intraoral dental floss stick cuts off, can haul out from the teeth space side for dental floss, thereby avoid the vertical tension of traditional dental floss stick tooth to be produced the sword formula that the turns dental floss blade of damage.
The scheme that solves the technology of the present invention problem is: turn sword formula dental floss blade, be made of guiding master slice, latch, cutting edge breach, handle, blade, blade aperture, the sub-sheet of guiding, pin hole and gathering sill.The outline of guiding master slice is an ellipse, has a rectilinear gathering sill on the edge of guiding master slice, and the edge of gathering sill passes through arc transition with the outward flange of guiding master slice.The gathering sill master slice that will lead is divided into the first half and Lower Half at vertical direction, the thickness of the first half of guiding master slice is half of the thickness of guiding master slice Lower Half, the lateral surface of the upper and lower half of guiding master slice is concordant, and the median plane of the thickness direction of the medial surface of the first half of guiding master slice and guiding master slice Lower Half is on same perpendicular.The thickness of sub-sheet of leading is identical with the first half thickness of guiding master slice, and the outline of the sub-sheet of guiding and the outer contour shape of the guiding master slice first half be the mirror image body each other.The transverse angle at 45 ° of gathering sill and guiding master slice is provided with the cutting edge breach of the fold-line-shaped that meets at right angles in the inner end of gathering sill.On the medial surface of the first half of the other guiding master slice in the both sides of cutting edge breach, a columniform latch is arranged respectively.The corresponding positions of medial surface at the sub-sheet of guiding is equipped with the pin hole corresponding with latch.Latch is in pin hole and both becomes the tight fit relation.The first half of sub-sheet and guiding master slice of leading merges as a whole.Blade is L shaped, on the L shaped inward flange of blade with cutting edge.Blade is installed between the medial surface of the medial surface of the sub-sheet of guiding and the master slice that leads, the cutting edge of blade stretches out from described cutting edge breach, have the blade aperture corresponding with the latch position on blade, each latch passes corresponding with it blade aperture, and becomes to assemble relation movingly with blade aperture.Columniform handle be positioned at the guiding master slice Lower Half the lower end and with the guiding master slice as a whole.
User is after using existing dental floss stick to remove tartar, first dental floss is moved to gingival position, the hand-held described handle integral body that master slice and the sub-sheet of guiding consist of that will lead stretches in the oral cavity again, move forward and backward handle, under the guide effect of the edge of gathering sill and the outer peripheral transition arc of guiding master slice, dental floss slips in gathering sill, when dental floss slips into the inner end of gathering sill, pull handle, dental floss is namely cut off by the L shaped cutting edge of described blade.At this moment, can successfully dental floss laterally be extracted out from the side of the gingival position of teeth space.
Adopt such scheme, compared with prior art, the present invention has following marked improvement:
1. can use the present invention that dental floss is cut off after using existing dental floss stick that the tartar cleaning is finished, dental floss can laterally be extracted out from the side of the gingival position of teeth space, because the gingival position width of teeth space is maximum, make so on the one hand dental floss lateral pull to tooth in extraction reach minimum, the more important thing is avoided that traditional dental floss stick produces in withdrawal process tooth is had vertical tension than macrolesion, thereby avoided the damage to root of the tooth and alveolar bone junction.
2. the present invention is only by pulling handle just dental floss can be disconnected, and is easy to operate.
3. be in the inner end of gathering sill due to the cutting edge of blade of the present invention, can weak oral mucosa do not damaged in operating process, have higher safety.
4. the arc transition design between gathering sill of the present invention and guiding master slice can facilitate user to need not to use mirror, only just can smoothly dental floss be inserted in gathering sill with feel, and it is quick that operation is very easy.
5. because the present invention has adopted L shaped blade structure, avoided the operational inconvenience of skidding on cutting edge because of dental floss and causing, greatly improved the cutting efficiency of blade.
