Description

Technical Field

[0001] The utility model relates to the technical field of oral medical instruments, in particular to a gum retractor. Background Art

[0002] Impacted teeth are a common disease in oral alveolar surgery, and minimally invasive tooth extraction is currently the most common choice. During the operation, a dental high-speed turbine is used to cut the tooth, but the patient's tongue is sometimes enlarged and the gums are often involuted due to their physiological morphology. Dental drills have a high rotation speed and strong cutting ability. If the operation is improper, it is easy to damage the patient's tongue and lingual gingival tissue during the operation, causing damage to blood vessels and nerves. In severe cases, it may even be impossible to recover for a long time after surgery.

[0003] The existing gum retractor is entirely on a flat surface, and when the doctor operates it, he / she inserts it from the corner of the patient's mouth on the opposite side to operate it. In order to protect the tongue and ensure that the end of the retractor goes deep into the gums, the gum retractor itself needs to be tilted. Since the retractor is entirely on a plane, the operation is limited and the operator's line of sight is blocked, which can easily cause tissue damage. Therefore, the utility model improves it. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the prior art retractor is entirely in a plane, which will limit the operation and block the operator's sight, which is easy to cause tissue damage.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A gum retractor, comprising, from left to right, a gripping portion, an "S"-shaped connecting portion, an extending portion, and a retractor portion, wherein the connection between the connecting portion and the extending portion is turned outward, so that the deflection angle between the connecting portion and the gripping portion is 3-10 degrees;

[0007] The connection between the hook portion and the extension portion is turned inward, so that the deflection angle between the hook portion and the extension portion is 3-10 degrees;

[0008] The deflection angle between the connecting portion and the holding portion is the same as the deflection angle between the hook portion and the extending portion.

[0009] Working principle and beneficial effects: By turning the connection between the connecting part and the extension part outward, and turning the connection between the hook part and the extension part inward, and the deflection angle between the connecting part and the holding part is the same as the deflection angle between the hook part and the extension part, the holding part, the connecting part, the extension part and the hook part are not in the same plane, and have a certain deflection angle to facilitate operation by the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the three-dimensional structure of the utility model.

[0011] In the figure: 1, gripping portion; 2, connecting portion; 3, extending portion; 4, hook portion. DETAILED DESCRIPTION

[0012] The present invention can be better understood according to the following embodiments.

[0013] The structures, proportions, sizes, etc. illustrated in the drawings of the specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "front", "back", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0014] like Figure 1 As shown,

[0015] Example

[0016] A gum retractor comprises, from left to right, a gripping portion 1, an "S"-shaped connecting portion 2, an extension portion 3 and a retractor portion 4. The connection between the connecting portion 2 and the extension portion 3 is turned outward, so that the deflection angle between the connecting portion 2 and the gripping portion 1 is 30-45 degrees. The connection between the retractor portion 4 and the extension portion 3 is turned inward, so that the deflection angle between the retractor portion 4 and the extension portion 3 is 30-45 degrees. The deflection angle between the connecting portion 2 and the gripping portion 1 is the same as the deflection angle between the retractor portion 4 and the extension portion 3.

[0017] The utility model flips the connection between the connection part 2 and the extension part 3 outward, flips the connection between the hook part 4 and the extension part 3 inward, and the deflection angle between the connection part 2 and the gripping part 1 is the same as the deflection angle between the hook part 4 and the extension part 3, so that the gripping part 1, the connection part 2, the extension part 3 and the hook part 4 are not in the same plane and have a certain deflection angle to facilitate operation by the operator.
