The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a tooth root file with bent angle protection device, includes the file body and stalk portion, stalk portion fixed mounting is in the top of the file body, the file body has the bent angle, demountable installation has the protective sheath on the bottom surface of stalk portion, the opening has been seted up on the length direction of protective sheath, the protective sheath card is established on the file body, and when the protective sheath parcel file body bent angle, protective sheath open-ended both ends joint.

The utility model discloses a tooth root file with bent angle protection device, demountable installation has the protective sheath on the bottom surface of stalk portion, is using the utility model discloses a before the tooth root file, dismantle the protective sheath from the stalk portion, the parcel is in the bent angle department of tooth root file, with the both ends joint of protective sheath open-ended, can establish at bent angle department with the cover that the protective sheath is firm, the protective sheath shelters from the blade of tooth root file bent angle department, after the tooth root file gets into the root canal, the blade that bent angle department was sheltered from can not carry out cutting work to the tissue of bent angle department to can not reject the tissue of bent angle department, the tissue of bent angle department has been protected, the painful burden of patient has been alleviateed, do not influence the filling of root canal on.

In order to realize that protective sheath demountable installation is at the stalk portion, the upper surface circumference equipartition of protective sheath has a plurality of connecting blocks, stalk portion and protective sheath are connected to the connecting block, be provided with the tear trace between connecting block and the protective sheath, when dismantling the protective sheath, along tear trace with the protective sheath from the stalk portion tear down can, convenient and fast.

In order to realize the open-ended both ends joint of protective sheath, be provided with draw-in groove and fixture block on two open-ended sides respectively, the card is seted up to the double-phase opposite side of draw-in groove and is established the recess, fixed mounting establishes the arch with the card that the recess matches and establishes on the fixture block, the protruding card of card is established and is established in the card establishes the recess.

In order to enable the protective sleeve to be better attached to the bending angle of the tooth root file, the protective sleeve is made of an elastic material.

The utility model has the advantages that the tooth root file with the bend angle protection device is detachably provided with the protective sleeve on the bottom surface of the handle part, before the tooth root file is used, the protective sleeve is detached from the handle part and wrapped at the bend angle of the tooth root file, the two ends of the opening of the protective sleeve are clamped, the protective sleeve can be firmly sleeved at the bend angle, the protective sleeve shields the cutting edge at the bend angle of the tooth root file, after the tooth root file enters the root canal, the shielded cutting edge at the bend angle can not cut the tissue at the bend angle, thereby the tissue at the bend angle can not be removed, the tissue at the bend angle is protected, the pain burden of a patient is lightened, and the filling of the root canal on the next step is not influenced; when the protective sleeve is detached, the protective sleeve is torn off from the handle part along the tearing mark, so that the operation is convenient and fast.
