Abstract
A kind of row's gum device, comprise handle and be connected to the working arm at handle two ends, its feature is: each working arm end profile of described row's gum device is equipped with a fabric wheel that can rotate, fabric wheel on one of them working arm is positioned at the left side of handle, fabric wheel on another working arm is positioned at the right side of handle, and line ball operation is carried out in the both sides that the fabric wheel on two working arms corresponds respectively to same tooth; Described fabric wheel is entomodont gear, and gear thickness is slightly less than the diameter of row's gum line.It is simple that this utility model has structure, easy to use, the advantage of favorable working performance.
Description
Technical field
This utility model and a kind of medical apparatus and instruments, especially a kind of row's gum device.
Background technology
Row's gum technology is in dental care, during the operation such as cervical caries hole and wedge shaped defect filling, tooth preparation, impression making and dummy cementation, need the method adopting mechanicalness and (or) Drug, gum edge is allowed to shrink, level in gingival sulcus fluid is controlled, make gingival sulcus occur gap and clear exposure operating area, be beneficial to treatment operation and impression making.Wherein the most frequently used is mechanicalness row gum method, is exactly the row's gum line selecting different-diameter according to the degree of depth of gingival sulcus and gum edge elasticity, utilizes the viscoelasticity of gingival soft tissue, push in gingival sulcus, to shrink gum edge with row's gum device.Require row's gum line uniform depth of press-in, do not exceed gum edge.The operation principle of traditional row's gum device directly repeatedly pushes along row's gum line with the end of working arm to be pressed in gingival sulcus, the end of its working arm is thin circle or round rectangle, active width is limited, and once pushing can only be pressed into row's gum line of 1-2mm, and efficiency is not high; And belonging to discontinuity press-in, compression distance is uneven, and the part between twice press-in is usually extruded and exceeds gum edge; In addition, if the follow-up pressing direction of the end of working arm is too partial to be not pressed into district, row's gum line that the excessive tractive of meeting has been pressed into, makes the row's gum line be pressed into deviate from.
Summary of the invention
This utility model provides a kind of row's gum device, its objective is to solve lower, the second-rate problem of traditional row's gum device row gum efficiency.
In order to solve the problems of the technologies described above, technical solutions of the utility model are: a kind of row's gum device, comprise handle and be connected to the working arm at handle two ends, its feature is: each working arm end profile of described row's gum device is equipped with a fabric wheel that can rotate, fabric wheel on one of them working arm is positioned at the left side of handle, fabric wheel on another working arm is positioned at the right side of handle, and line ball operation is carried out in the both sides that the fabric wheel on two working arms corresponds respectively to same tooth; Described fabric wheel is entomodont gear, and edge serration is conducive to increasing the friction with row's gum line, and gear thickness is slightly less than the diameter of row's gum line.
Beneficial effect: this utility model has the following advantages: 1. fabric wheel is continuous print rolling pushing when pressure gum line, and row's gum line pressure that once just can complete a tooth side enters, and improves work efficiency high; 2., because fabric wheel is that continuous print rolls pushing when pressure gum line, it is consistent that row's gum line pressure enters uniform depth, the problem that the row's of avoiding gum line is extruded; 3., because fabric wheel can rotate, can discharge at any time row's gum line traction force, the row's gum line be pressed into can not be made to deviate from; 4. fabric wheel is entomodont gear, and edge serration is conducive to increasing the friction with row's gum line, smoothly the row's gum tape be not pressed into is entered gingival sulcus; 5. this utility model has structure simply, easy to use, the advantage of favorable working performance.

Fig. 3 is utility model works schematic diagram one.
Fig. 4 is utility model works schematic diagram two.
In figure, 1 is handle, and 2 is working arms, and 3 is fabric wheels, and 4 is teeth, and 5 is row's gum lines, and 6 is gum edge, and 7 is gingival sulcus.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of row's gum device, comprise handle 1 and be connected to the working arm 2 at handle 1 two ends, one of them working arm 2 end bends to handle left direction, and another working arm 2 end bends to handle right direction; Each working arm 2 end profile of described row's gum device is equipped with a fabric wheel 3 that can rotate, namely fabric wheel 3 is fixed on after on working arm 2 by bearing pin and realizes rotating; Fabric wheel 3 on one of them working arm 2 is positioned at the left side of handle 1, and the fabric wheel 3 on another working arm 2 is positioned at the right side of handle 1, and line ball operation is carried out in the both sides that the fabric wheel 3 on two working arms 2 corresponds respectively to same tooth; Described fabric wheel 3 is entomodont gear, and gear thickness is slightly less than the diameter of row's gum line.
As shown in Figure 3 and Figure 4, one end of row's gum line 5 is with in other apparatuses press-in gingival sulcus 7, fabric wheel 3 on working arm 2 just along gingival sulcus 7 by row's gum line 5 to pushing row gum line 5 in the gingival sulcus 7 of the also row of press-in gum line 5, working arm 2 remains to the pressure bottom gingival sulcus 7 in the process of translation, fabric wheel 3 rotates under the promotion of working arm 2, brings row's gum line 5 in front into gingival sulcus 7 successively.
