Description
Technical field
This utility model belongs to medical apparatus and instruments, relates generally to a kind of tooth body reparation surgical instrument.
Background technology
At present, the row's dentiscalprum that uses in the repair of tooth body all is to adopt the rectangular flat board of thin type, its top row pressure gum line position to be straight linear structure, in actual medical is manipulated, because all there is the physiology curvature at people's tooth body cervical region and gingiva gingival sulcus position, so, during above-mentioned existing tooth body reparation row dentiscalprum line ball, not only the line ball difficulty, increase the weight of the patient suffering, especially locate the easy damaged gingiva at tooth axon face angle, and working performance is low, the activity duration long, medical worker's labor intensity is big.
Summary of the invention
The purpose of this utility model is exactly the problem that exists at above-mentioned prior art, and design provides a kind of tooth body reparation row dentiscalprum of new construction, reaches the line ball simple and convenient, alleviates the patient suffering, the line ball operating speed is fast, reduce the purpose of medical worker's labor intensity.
Basic design of the present utility model is, tooth body reparation row dentiscalprum comprises row gum portion and handle portion, and row's gum end face integral body of row's gum portion is the evagination arc shaped, and row's gum end face of convex arc wire is provided with row's gum wire casing outside, and the cross section of row's gum portion is arc surfaced.
This utility model reasonable in design, simple, easy for operation, surgical operation efficient height, quality are good.
Description of drawings
Fig. 1 is a tooth body reparation row dentiscalprum population structure sketch map;
Fig. 2 is row's gum A-A of portion profile among Fig. 1.
Piece number explanation among the figure:
1, row's gum wire casing, 2, row's gum portion, 3, handle portion.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the utility model is described in detail.Tooth body reparation row dentiscalprum comprises row gum portion 2 and handle portion 3, and row's gum end face integral body of row's gum portion 2 is the evagination arc shaped, and row's gum end face of convex arc wire is provided with row's gum wire casing 1 outside, and the cross section of row's gum portion 2 is arc surfaced.
When manipulating, hold handle portion 3, between patient's tooth body cervical region and gingiva gingival sulcus, the row's of utilization gum wire casing 1 is located at the gum line pressure in the gingival sulcus, finishes operation technique with the arc shaped termination that has row's gum wire casing 1 of row gum portion 2 front ends.The whole arc surfaced of row's gum portion 2 cross sections and the arc shaped structure of row's gum end face, the physiological curve shape that meets tooth body organ is very easy to operation and uses, and has increased substantially the working performance and the quality of line ball, reduce tissue injury, and alleviated patient's misery.Row's gum wire casing 1 can be pressed on the gum line in the gingival sulcus reliably, fully exposes the tooth preparation edge, guarantees that die produces quality.
