Description

Correction proximal surface stripping piece cuts emery stick

Technical field

The utility model is related to a kind of medical instruments, are exactly that a kind of correction proximal surface stripping piece cuts emery stick.

Background technology

During orthodontic treatment, it is sometimes desirable to the processing of proximal surface stripping, common proximal surface stripping tool are carried out to tooth For, vehicle needle, emery stick, sand piece etc..Wherein emery stick is divided to two kinds, the first is common manual emery stick, and length can be cut out as needed, The shortcomings that manual emery stick is：Emery stick is short and small, and hand-held is relatively tired, and oral cavity space is narrow, and manual emery stick operates not square Just, bruting process takes longer, and discomfort is caused to patient.Second is machine emery stick, and this emery stick and stainless steel maintenance handle are It is connected in integrated, additional motor driving.Machine emery stick shortcoming is：It operates and is absolutely unsafe, the part for being also easy to produce tooth is excessive The normal morphology of tooth is cut and changed to piece, and emery stick can only generally use 3-5 tooth or so, after use, emery stick and solid Position handle is due to being integrated, so will abandon, expends more.

One application No. is 201610077180.2 (publication No. CN105596090A) Chinese invention patent《A kind of tooth Piece cutting tool》, including tool heads and handle, tool heads include the knife rest for setting emery stick, and knife rest includes fixing emery stick Two fixing ends, be provided with a regulating device in one of fixing end, regulating device is for adjusting between two fixing ends Spacing.Disclosed tooth piece cutting tool needs progress both ends to fix in assembling, also needs to adjust spacing, behaviour after fixed It bothers, front tool volume is larger, is not easy to operate in the oral cavity of narrow space, and front-end architecture is complicated, and piece cuts operation Tool is difficult to clean totally later, can bring security risk to oral cavity patient later.

Invention content

Technical problem to be solved in the utility model be for the above-mentioned prior art present situation and provide it is a kind of simple in structure, The correction proximal surface stripping piece of changeable type cuts emery stick.

Technical solution is used by the utility model solves above-mentioned technical problem：A kind of correction proximal surface stripping piece cuts sand Item, including maintenance handle, it is characterized in that：The front end projection of maintenance handle has the retention head of retention grooves, further includes in retention head Piece cuts emery stick, and piece cuts emery stick with buckling groove, and piece is cut emery stick and is removably connected in retention head by buckling groove thereon In retention grooves.

As an improvement, above-mentioned buckling groove is beloid structure, rear end width matches with maintenance head width, buckling groove This structure can realize that subsequent sheet is cut emery stick and is connected in retention grooves.

Above-mentioned retention grooves match with clamping groove shape and size, in this way when installation sheet cuts emery stick on maintenance handle Retention head can be nested into the buckling groove rear end that piece cuts emery stick.

As an improvement, sheet above cuts emery stick one side or two sides is equipped with part containing sand.

As an improvement, sheet above, which cuts part containing sand on emery stick, is set on clamping front of the slot either the buckling groove left and right sides or card Access slot or so side.

As an improvement, above-mentioned maintenance handle material is plastics, ceramics or stainless steel.

Compared with prior art, the utility model has the advantage of：The utility model is simple in structure, convenient for hand-held, cleaning It is convenient；Front end is small, is suitble to operate in oral cavity；It is separable that piece, which cuts emery stick and maintenance handle, cuts emery stick in piece in this way and uses After, the piece that only can more renew cuts emery stick, and without replacing maintenance handle, dismounting is quick；It, can when maintenance handle material is plastics To be abandoned simultaneously with emery stick.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing embodiment.

As shown in Figs. 1-5, a kind of correction proximal surface stripping piece cuts emery stick, and including maintenance handle 1, the 1 front end projection of maintenance handle has The retention head 2 of retention grooves 21 further includes the piece in retention head 2 and cuts emery stick 3, and piece cuts emery stick 3 with buckling groove 32, and piece is cut Emery stick 3 is removably connected to by buckling groove 32 thereon in the retention grooves 21 in retention head 2.Buckling groove 32 is beloid Structure, rear end width matches with 2 width of retention head.Fig. 3 a~3d cut emery stick 3 for the piece of different shape buckling groove 32 and illustrate Figure, in addition to shape shown in figure, buckling groove 32 can also have other variations.Retention grooves 21 and 32 shape of buckling groove and size Match.Piece cuts 3 one side of emery stick or two sides is equipped with part containing sand 31.Piece cuts part containing sand 31 on emery stick 3 and is set on buckling groove 32 The front end either left and right sides of buckling groove 32 or 32 or so side of buckling groove.1 material of maintenance handle is plastics, ceramics or stainless steel Matter.

When installation sheet cuts emery stick 3, first the retention head 2 on maintenance handle 1 is nested into after piece cuts the buckling groove 32 of emery stick 3 End, the buckling groove that piece is cut to emery stick 3 elapses on both sides backward about 32 along the retention grooves 32 in retention head 2, behind buckling groove 32 When end is mutually low with 2 side of retention head, it can realize that piece is cut the safe of emery stick 3 and connect.When dismantling, pushed away i.e. according to above-mentioned steps are counter It can.If maintenance handle 1 is plastic material, emery stick 3 can be cut after use with piece while is abandoned.

Although the preferred embodiment of the present invention described in detail above, it is to be clearly understood that for this field Technical staff for, the invention may be variously modified and varied.That is made all within the spirits and principles of the present invention appoints What modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
