Abstract
The invention discloses a gingival retraction device, which comprises a handle and working arms which are connected to two ends of the handle; the gingival retraction device is characterized in that a rotatable cord pressing wheel is arranged on the side face of the tail end of each of the working arms of the gingival retraction device, wherein the cord pressing wheel on one of the working arms is arranged on the left side of the handle and the cord pressing wheel on the other working arm is arranged on the right side of the handle; the cord pressing wheels on the two working arms are used for conducting cord pressing operation relative to two sides of a same tooth; the cord pressing wheels are fine-toothed gears; and the thicknesses of the gears are slightly less than the diameter of a gingival retraction cord. The gingival retraction device disclosed by the invention has the advantages of simple structure, convenient use and good working performance.
Description
Technical field
The present invention 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, the method needing to adopt mechanicalness and (or) Drug, gum edge is allowed to shrink, level in gingival sulcus fluid is controlled, make gingival sulcus gap occur and clearly expose operating area, be beneficial to treatment operation and impression making.Most common of which is mechanicalness row's gum method, it is simply that selects the retraction cords of different-diameter according to the degree of depth of gingival sulcus and gum edge elasticity, utilizes the viscoelasticity of gingival soft tissue, pushes in gingival sulcus with row's gum device, to shrink gum edge.Require the retraction cords uniform depth of press-in, do not exceed gum edge.The operation principle of traditional row's gum device is repeatedly to push directed along retraction cords 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, once pushes the retraction cords that can only be pressed into 1-2mm, inefficient；And belonging to discontinuity press-in, compression distance is uneven, and the part between twice press-in is usually extruded and exceeds gum edge；If it addition, the follow-up pressing direction of the end of working arm is excessively partial to and is not pressed into district, the retraction cords that the excessive tractive of meeting has been pressed into, make the retraction cords being pressed into deviate from.
Summary of the invention
The present invention provides a kind of row's gum device, its purpose is to solve the problem that traditional row's gum device row's gum is inefficient, second-rate.
In order to solve above-mentioned technical problem, technical solution of the present invention is: a kind of row's gum device, including handle and the working arm being connected to handle two ends, it is characterized in that: be equipped with a fabric wheel that can rotate in each working arm end profile of described row's gum device, 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 the fabric wheel on two working arms corresponds respectively to the both sides of same tooth and carries out line ball operation；Described fabric wheel is entomodont gear, and edge serration is conducive to increasing the friction with retraction cords, and gear thickness is slightly less than the diameter of retraction cords.
Beneficial effect: the invention have the advantages that 1. fabric wheels are that continuous print rolls pushing when pressing retraction cords, once just can complete the retraction cords press-in of a tooth side, improve work efficiency height；2. owing to fabric wheel is that continuous print rolls and pushes when pressing retraction cords, retraction cords compression distance uniformity, it is to avoid the problem that retraction cords is extruded；3., owing to fabric wheel can rotate, it is possible to discharge at any time retraction cords traction force, the retraction cords being pressed into will not be made to deviate from；4. fabric wheel is entomodont gear, and edge serration is conducive to increasing the friction with retraction cords, in order to bring the retraction cords not being pressed into into gingival sulcus smoothly；5. the present invention has simple in construction, easy to use, the advantage of favorable working performance.

Fig. 3 is operating diagram one of the present invention.
Fig. 4 is operating diagram two of the present invention.
In figure, 1 is handle, and 2 is working arm, and 3 is fabric wheel, and 4 is tooth, and 5 is retraction cords, 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, including handle 1 and the working arm 2 being connected to handle 1 two ends, one of them working arm 2 end bends to left handle direction, and another working arm 2 end bends to right handle direction；Being equipped with a fabric wheel 3 that can rotate in each working arm 2 end profile of described row's gum device, namely fabric wheel 3 realizes after being fixed on working arm 2 by bearing pin 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 the fabric wheel 3 on two working arms 2 corresponds respectively to the both sides of same tooth and carries out line ball operation；Described fabric wheel 3 is entomodont gear, and gear thickness is slightly less than the diameter of retraction cords.
As shown in Figure 3 and Figure 4, one end of retraction cords 5 is pressed in gingival sulcus 7 with other apparatuses, fabric wheel 3 on working arm 2 is along gingival sulcus 7 and in the gingival sulcus 7 be not also pressed into retraction cords 5, retraction cords 5 is pushed retraction cords 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 the retraction cords 5 in front into gingival sulcus 7 successively.
