Description
Technical field
This utility model belongs to Special medical equipment field, oral cavity, relates to a kind of deciduous teeth replaceable head section dental excavator spoon particularly.
Background technology
Oral disease is a kind of commonly encountered diseases, be wherein the highest with the sickness rate of dental caries, treatment dental caries primarily removes the dental caries bad dentine that dental caries damage position, then carries out filling, general removal dental caries damage position and adopt in two ways more: 1, use high speed electric drill to remove, this mode goes dental caries fast, but cost is high, not easily grasps the degree of depth, easy accidental injury dental pulp, and for child patient, easily produce the psychology of fear, and many positions use high speed drill to clear up cavity as do not related to morsal Proximal caries; 2, use the replaceable head dental excavator spoon of deciduous teeth, easily control to excavate the degree of depth, the position that especially high speed drill cannot be cleared up is generally used, and especially for the deciduous teeth of small volume, as much as possible remains healthy tissue of tooth.But current excavator spoon working head and handle are fixing, and working head angle is single, operate restricted during use, the deciduous molar dental caries particularly removing diverse location damage, can not flexible operating.
By retrieval, find following relevant to the application patent document, concrete disclosure is as follows:
CN201189209 discloses a kind of dental excavator spoon, comprise handle, the curved neck at handle two ends and working head, described working head can revolve movable joint by screw-type and cervical region is hinged, unscrew and can revolve movable joint, working head can opposite handle and neck rotation, screw and can revolve movable joint, working head and handle and cervical region are fixed.
Find by comparing documents, the application is different from the emphasis of the technical scheme of documents, provides a kind of operation more simple device, has good effect.
Utility model content
The content of technical scheme to be solved in the utility model is as follows:
A kind of deciduous teeth replaceable head section dental excavator spoon, handle, working head, is characterized in that: one end of handle has and is coaxially shaped with screw, and working head cervical region outer rim is shaped with screw thread, the screw of coaxial threaded Engaging handle end, coaxially wraps up skid resistant course in the lower end outer rim of handle.
And described working head comprises 45 ° of curved neck working heads, 90 ° of curved neck working heads and 120 ° of curved neck working heads.
The beneficial effects of the utility model are:
1, this utility model has that structure is simple, handled easily, and arbitrarily can replace working head according to the diverse location of suffering from dental cavity.Facilitate the removal of detritus in cavity, reduce the feared state of mind of child patient, farthest retain healthy tissue of tooth, meanwhile, improve clinical efficiency.
2, it is simple that the deciduous teeth replaceable head section dental excavator spoon that this utility model improves has structure, easy to operate advantage, the interchangeable dental excavator spoon of working head, working head is by being screwed on handle, when unscrewing screw thread, other angle working heads replaceable, to be applicable to the dental caries of excavating diverse location, handled easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, and Fig. 1-1 is 90 ° of curved neck working head structure schematic diagrams, and Fig. 1-2 is 120 ° of curved neck working heads, and Fig. 1-3 is 45 ° of curved neck working heads.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of deciduous teeth replaceable head section dental excavator spoon, handle 3,45 ° of curved neck working heads 6,90 ° of curved neck working heads 1,120 ° of curved neck working heads 5, handle is generally the convenient cylindrical or flat tongue shape gripped, material can be rustless steel, one end of handle has and is coaxially shaped with screw, and screw thread is convenient to screw in working head.Working head is arranged on handle one end, and working head cervical region outer rim is shaped with screw thread 2, the screw of coaxial threaded Engaging handle end, and be convenient to screw with handle, working head all adopts material manufacture of not easily getting rusty, as rustless steel etc.45 ° of curved neck working heads are tightened by cervical region spiral shell button and handle threads end, when unscrewing screw thread, and replaceable 90 ° of curved neck working heads, 120 ° of curved neck working heads.
In order to increase the hand-held torsion of handle, coaxially wrap up skid resistant course 4 in the lower end outer rim of handle.
Using method of the present utility model is:
During use, select according to the position of patient's dental caries and screw unspecified angle working head, using dental excavator spoon routinely, again can replace other angle working heads as required.
