Description
Technical field
This utility model belongs to type medical instrument for dental use trouble tooth being carried out to root canal, is specifically related to a kind of safety and opens the special dental sewing machine needle of roof of pulp chamber.
Background technology
Dental pulp disease and periapical disease are the common diseases of the department of stomatology, preserve patient teeth, dental pulp is modern stomatologic therapeutic purposes, and root canal is the most common and the most effective Therapeutic Method at present.The principle of root canal operation is the most of infectious agent removed by machinery and chemical method in root pipe, and by filling root pipe, closing bizet, prevents the healing of the periapical lesion that periapical lesion or promotion have occurred.
Root canal generally comprises following steps:
One, root canal preparation: open marrow, thoroughly knows the pulp tissue of pathological changes necrosis, measures sono-explorer, makes root pipe and expands;
Two, root canal irrigation: the operation repeatedly carried out in root canal, rinses well sources of infection such as fine debris organic in root pipe and the tiny broken ends of sclerous tissues that machines away;
Three, root canal disinfection: drug disinfection is the most frequently used, be dip in a little medicinal liquid with cotton sth. made by twisting to be placed in root pipe, hole temporary stopping seals;
Four, root canal deviation: last step being root canal therapy is also most important step in root canal, commonly adds with root canal filling agent and uses gutta percha point root canal filling, make root canal system energy tight closure on coming personally at present.
Opening to contact completely and set up extremely important for the location of root canal orifice, the straight line of equipment root canal orifice in room, endodontic procedure the marrow being invaded by pathogen top, traditional dental sewing machine needle has the function of cutting due to its tip, while emedullating, often injure the anatomical structure of roof of pulp chamber, cause the Anatomical aberration of root canal orifice.
Utility model content
This utility model has cutting function to solve existing dental sewing machine needle due to tip, the anatomical structure of roof of pulp chamber is injured while emedullating, cause the problem of the Anatomical aberration of root canal orifice, and provide a kind of safety to open the special dental sewing machine needle of roof of pulp chamber, doctor opens in the process of roof of pulp chamber and prevents car pin to injure the anatomical structure of roof of pulp chamber, prevents the Anatomical aberration of root canal orifice.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is:
Safety opens the special dental sewing machine needle of roof of pulp chamber, comprises handle, and the front end of described handle is connected with operate portions, it is characterized in that, the outer surface cloth of described operate portions is provided with corundum; The front end of described operate portions is provided with the head protector of smooth outer surface, and described head protector is spherical or hemispherical.
Described operate portions is cylindric or round table-like.
The outer surface of described operate portions offers many spiral helicine work edges.
The rotation direction of described work edge is left-handed.
Compared with prior art, this utility model has following beneficial effect:
Safety of the present utility model opens the special dental sewing machine needle of roof of pulp chamber, comprises handle, and the front end of described handle is connected with operate portions, and the outer surface cloth of described operate portions is provided with corundum; The front end of described operate portions is provided with the head protector of smooth outer surface, and described head protector is spherical or hemispherical.This utility model arranges head protector by the front end in operate portions, and head protector is spherical or hemispherical, spherical or hemispheric head protector prevents doctor to open car pin in the process of roof of pulp chamber and injures the anatomical structure of roof of pulp chamber, prevent the Anatomical aberration of root canal orifice, thus ensure safety open roof of pulp chamber, be convenient to the root canal of postorder.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing car pin;
Fig. 2 is the structural representation of this utility model embodiment one;
Fig. 3 is the structural representation of this utility model embodiment two;
Labelling in figure: 1, handle, 2, operate portions, 3, corundum, 4, head protector, 5, work edge.
Detailed description of the invention
Below in conjunction with embodiment, the utility model will be further described, and described embodiment is only this utility model part embodiment, is not whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art, not making other embodiments used obtained under creative work prerequisite, belongs to protection domain of the present utility model.
Composition graphs 1, existing car pin, owing to having tip, often injures the anatomical structure of roof of pulp chamber while emedullating, and causes the Anatomical aberration of root canal orifice.
Composition graphs 2 and Fig. 3, safety of the present utility model opens the special dental sewing machine needle of roof of pulp chamber, comprise handle 1, the front end of described handle 1 is connected with operate portions 2, the outer surface cloth of described operate portions 2 is provided with corundum 3, corundum belongs to prior art, and those skilled in the art can understand and understand, and does not repeat them here.The front end of described operate portions 2 is provided with the head protector 4 of smooth outer surface, and described head protector 4 is in spherical or hemispherical.This utility model is by arranging head protector 4 in the front end of operate portions 2, and head protector 4 is in spherical or hemispherical, spherical or hemispheric head protector 4 prevents doctor to open car pin in the process of roof of pulp chamber and injures the anatomical structure of roof of pulp chamber, prevent the Anatomical aberration of root canal orifice, thus ensure safety open roof of pulp chamber, be convenient to the root canal of postorder.
As a kind of preferred mode of this utility model, operate portions 2 is in cylindric or round table-like.
The outer surface of operate portions 2 of the present utility model offers many spiral helicine work edges 5, is convenient to increase work efficiency.As a kind of preferred mode of this utility model, the rotation direction of work edge 5 is left-handed, makes apparatus direction of rotation contrary with the hand of spiral of work edge, even if thus realize instant cutting and immediately enter, immediately enter instant excellent operation duty of cutting, improve practicality of the present utility model.
