The enamel chisel is a hand-held instrument in stomatology department, when making a fixed crown, the shoulder is trimmed after the tooth body is prepared, the blade part has a sharp edge, just like an axe, but the blade is bent, a proper and smooth edge completion line can be formed, the inner angle of the shoulder is clearer, the shoulder is easy to realize to be smooth, and therefore the crown edge is ensured to be closed. However, the length of the enamel chisel edge for oral clinical use is fixed, the width of the shoulder varies greatly, and the enamel chisel edge rarely reaches the length. In this case, the enamel chisel edge partially contacts the gum, and the gingival tissue is extremely vulnerable to injury during the procedure for alignment with the gingival shoulder or subgingival shoulder. The above problems greatly limit the clinical use of enamel chisels.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems in the prior art, the utility model provides an enamel chisel edge length adjusting sleeve, which changes the length of an enamel chisel edge by adjusting the position of an adjusting part, operates on shoulders with different widths, and can push away and protect gingival tissues to realize the operation of subgingival shoulders.
The technical scheme adopted by the utility model is as follows:
the utility model provides an enamel chisel cutting edge length adjustment cover, includes fixed cover, adjusting collar and regulation joint, fixed cover is connected as a whole through adjusting the joint and adjusting the cover, and fixed cover is used for the cover on the connecting rod of enamel chisel, adjusts the cover and is used for wrapping up partly enamel chisel cutting edge, and the length of adjusting the cover on enamel chisel cutting edge is adjustable.
The fixed sleeve, the adjusting sleeve and the adjusting joint are all made of elastic materials.
The elastic material is a high-temperature-resistant silicon rubber material.
The fixed sleeve, the adjusting sleeve and the adjusting joint are hollow tubes.
The hollow part of the fixing sleeve has a shape matched with the enamel chisel connecting rod.
The hollow portion of the adjustment sleeve has a shape that fits the enamel chisel edge.
The adjusting joint is a telescopic hollow corrugated pipe.
The fixing sleeve is provided with a circular hollow part.
The adjustment sleeve has a flat hollow.
The outer wall of the adjusting joint is provided with a plurality of layers of folds.
The utility model has the technical effects that:
the length of the cutting edge is adjusted by adjusting the range of the cutting edge of the enamel chisel, so that the enamel chisel is suitable for clinical use of shoulders with different widths, and meanwhile, after the cutting edge is wrapped by the adjusting sleeve, the gingival tissue is prevented from being damaged by overlong cutting edges; the height difference between the adjusting sleeve and the cutting edge realizes the function of depressing the gum, is convenient for the operation of the subgingival shoulder, and can enlarge the clinical application range of the enamel chisel. In addition, the adjusting sleeve is fixed at the enamel chisel part, the conventional use of the enamel chisel is not interfered, the whole structure is simple, high-temperature disinfection can be realized, and the manufacturing cost is low.

Wherein:
10-fixed sleeve, 20-adjusting sleeve, 30-adjusting joint, 100-connecting rod, 200-enamel chisel edge.
Detailed Description
The following detailed description is given with reference to specific examples, but the scope of the present invention is not limited by the specific embodiments.
As shown in fig. 1, the prior art enamel chisel consists of a cylindrical connecting rod 100 and a flat enamel chisel edge 200, wherein the connecting rod 100 is located between a handle and a cutter head
The utility model provides an enamel chisel blade length adjusting sleeve, which comprises a fixed sleeve 10, an adjusting sleeve 20 and an adjusting joint 30, wherein the fixed sleeve 10 is connected with the adjusting sleeve 20 into a whole through the adjusting joint 30, the fixed sleeve 10 is used for being sleeved on a connecting rod 100 of an enamel chisel, the adjusting sleeve 20 is used for wrapping a part of the enamel chisel blade 200, and the position of the adjusting sleeve 20 on the enamel chisel blade 200 is adjustable, as shown in the right figure 2.
The fixing sleeve 10, the adjusting sleeve 20 and the adjusting joint 30 are hollow tubes made of elastic materials, the hollow tubes can deform after being pulled, the hollow part of the fixing sleeve 10 has a shape matched with the enamel chisel connecting rod 100, and in the embodiment, the fixing sleeve 10 has a circular hollow part.
The hollow part of the adjustment sleeve 20 has a shape adapted to the enamel chisel edge, in this embodiment the adjustment sleeve has a flat-mouthed hollow part.
The adjusting joint 30 is a telescopic hollow corrugated pipe, and a plurality of layers of folds are arranged outside the hollow corrugated pipe, and the length of the adjusting joint 30 is changed by stretching and retracting the plurality of layers of folds.
Specifically, the elastic material is a high-temperature-resistant silicon rubber material.
