Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of crown remover.
Background technology
Facing being installed for sick and weak tooth is dentistry restorative procedure commonly used, yet, facing in use, owing to various factors is damaged, when needs are removed, the apparatus that uses is exactly a crown remover, one of existing crown remover drops on corona and puts, be with one on its bar and slide hammer, shake facing by the impact kinetic energy that moves sliding hammer generation it is come off, still, but have the following disadvantages in actual use: the lower edge that 1, must hook the corona cover because of its hook end, the hook end generally can be oppressed gingiva like this, can cause gingival hemorrhage because of carelessness, even tear; 2, easily landing of hook end when removing the hat cover, the oral mucosa that can damage the patient this moment causes unnecessary misery to the patient; 3, since force way be 2 stressed, so corona overlaps discontinuity, removal is wasted time and energy.
The utility model content
Technical assignment of the present utility model is to provide a kind of crown remover at above the deficiencies in the prior art.
The technical solution of the utility model is: crown remover, comprise slide bar and sliding hammer, and be provided with handle at an end of described slide bar, be provided with the clamping tweezer at the other end of described slide bar, described clamping tweezer is flat-shaped arc, is provided with anti-skidding stricture of vagina at the inner surface of described clamping tweezer.
Junction at described slide bar and clamping tweezer is provided with locking knob, and purpose is to make the tight clamping corona of clamping tweezer cover, so that go the hat operation.
Described slide bar and clamping tweezer screw thread join, and purpose is to be convenient to change and sterilization.
During use, two most advanced and sophisticated places of clamping tweezer are clamped in corona overlap below the peripheral highlight, then, screw locking knob, make its clamping corona cover tightly, move sliding hammer, the corona cover will be removed under the impact kinetic energy effect that sliding hammer produces like a cork, and can not injure oral cavity tissue.
This utility model compared with prior art has following useful effect: 1, the clamping tweezer adopts flat-shaped arc, when going to be preced with, need only be clamped in corona to two most advanced and sophisticated places and get final product below overlapping peripheral highlight, can not contact gingiva, thereby, safe and reliable, and stressed even, remove the corona cover easily; 2, adopt locking knob, the clamping dynamics that can regulate the clamping tweezer makes it more firm, is difficult for landing, the convenient corona cover of removing.
