The utility model relates to a tartar cleaner, and especially relates to a cylinder edge type dental floss rod. The cylinder edge type dental floss rod is composed of an arc-shaped rack, a floss knot, an anti-sliding ring, a cutting sleeve, a sliding-stopping sheet, a dental floss, a rear branch, and a front branch. The arc-shaped rack is inverted U-shaped; a rod-shaped handle is combined with the arc-shaped rack to form a whole body. One end of the dental floss is connected with the front branch; the middle part of the dental floss passes through a transverse through hole at the lower end of the rear branch; the other end of the dental floss extends out from a vertical through hole at the joint of the handle and the arc-shaped rack; a floss knot is at an end of the extending part; the handle is sleeved with the cutting sleeve; the end of the cutting sleeve facing the floss knot has an cutting edge. The utility model can minimize the transverse pulling force applied to teeth during the drawing process of the dental floss, and also avoid vertical pulling force which is generated during the drawing process of a traditional dental floss rod and has great damage to teeth.

Description

Tube sword formula dental floss stick

Technical field

This utility model relates to a kind of tartar cleaner, particularly relates to a kind of sword formula dental floss stick.

Background technology

Existing tartar cleaner is commonly called as dental floss stick, normally is made up of by exceptionally straight polyester fiber dental floss a segmental support and one, earlier dental floss is pressed in the teeth space during use, and then moves around in the teeth space, and tartar is taken out of, dental floss is extracted from teeth space again.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 the reasons are as follows:

1. the shape of corona has up big and down small characteristic usually, and this has up-small and down-big characteristic (referring to Figure of description 1) with regard to making the teeth space between adjacent two teeth.Therefore when using dental floss stick, can obviously feel; Process dental floss being pressed into teeth space is relatively required great effort; In case but dental floss is when entering into teeth space near the position of gingiva, it is just obviously much laborsaving to move dental floss, and the process that dental floss is extracted from teeth space is once more relatively required great effort.

2. the masticatory function of tooth has determined tooth to have the stronger ability of bearing vertical pressure, but the up big and down small structure of root of the tooth is born a little less than the ability relative thin of pulling force tooth.

In view of above-mentioned 2 points, be that dental floss has applied bigger pulling force to tooth therefore at the process nature that dental floss is extracted from teeth space, teeth space is narrow more, and pulling force is big more, and is also just big more to the infringement of root of the tooth.The existing dental floss stick of life-time service applies pulling force to tooth repeatedly, can cut down the adhesion between root of the tooth and the alveolar bone significantly, causes the loosening of root of the tooth, and therefore many patients feel that the teeth space tooth of picking one's teeth more is loosening more.This has been since dental floss stick comes out, need solve for many years 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.

The utility model content

This utility model provides a kind of tube sword formula dental floss stick that in rejecting the tartar process, can not produce pulling force to tooth for solving the deficiency of prior art.

The scheme that solves this utility model technical problem is: tube sword formula dental floss stick, by segmental support, toe-in, anti-slip ring, cutting cover, on-slip sheet, dental floss, prop up the back and preceding constitute.Wherein segmental support is a reverse U shape, and segmental support comprises horizontal stripe and is preceding of one and afterwards props up with the horizontal stripe two ends.Shaft-like handle and segmental support are combined as a whole.The binding site of handle and segmental support is positioned at the joint of the back and the horizontal stripe of segmental support.Material is that an end of the dental floss of polyester fiber is connected with preceding lower end; The cross through hole of a lower end, back is run through at the middle part of dental floss; The other end of dental floss stretches out from the vertical through holes of handle and segmental support junction from bottom to top; There is a toe-in termination of extension, and the diameter of toe-in is greater than the interior diameter of the vertical through holes of handle.Have at the middle part of handle one with handle be holistic on-slip sheet.On the handle between on-slip sheet and the said vertical through holes, be with the cutting cover that is in active relationship with handle, the cutting cover has cutting edge towards an end of toe-in, on the outer surface of cutting cover anti-slip ring is arranged, and anti-slip ring is to be holistic annular protrusion with the cutting cover.

User will the back and dental floss between preceding is pressed into the teeth space depths and level moves around, with calculus removal after; Earlier dental floss is moved to gingival position; Promote the cutting cover more forward, the cutting edge that makes cutting cover end is the end excision of toe-in from dental floss, and the direction level of again segmental support being propped up the place forward drags; The end that dental floss is in the vertical through holes of handle skids off from the cross through hole of the vertical through holes of handle and back successively, and finally the side from the gingival position of teeth space laterally skids off.

Adopt such scheme, compared with prior art, the utlity model has following marked improvement:

1. because can finishing the back in the tartar cleaning, this utility model cuts off dental floss; 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 dental floss lateral pull to tooth in extraction reach minimum so on the one hand, the more important thing is avoided that traditional dental floss stick produces in withdrawal process tooth is had the vertical pulling force than macrolesion property, thereby avoided damage to root of the tooth and alveolar bone junction.

2. this utility model only just can cut off dental floss through promoting the cutting cover, and is easy to operate.
