Detailed Description

The following is a further detailed description of the embodiments:

Example 1

Referring to fig. 1 and 2, the present utility model provides a bone flap retractor, which includes a handle 1 and a retractor portion 2 disposed at one end of the handle 1, wherein the handle 1 includes a middle portion 11, two extending portions 12 connected to two ends of the middle portion 11 in a length direction and extending upward and downward respectively, and an included angle between the two extending portions 12 and the middle portion 11 is smaller than 180 degrees, and the retractor portion 2 is disposed at one end of one extending portion 12 far away from the middle portion 11. The oral visual field of the patient is pulled by the extension part 12, and then the tissue valve is fixed and pulled by the drag hook part 2 to turn over the valve and remove bones, so that the turning over of the valve and the bone removal can be completed without other tools, and the operation is more convenient.

With continued reference to fig. 3, 4 and 5, in order to make the extension 12 better for supporting the oral cavity during operation, in this embodiment, the angles between the extension 12 and the middle portion are 120 degrees, and the extension 12 extends up and down toward the two ends of the middle portion 11, so that the extension 12 and the middle portion 11 integrally form a Z-like structure. When the medical staff is used, medical staff grips the middle part 11, stretches the extension part 12 and the drag hook part 2 into the oral cavity, when the extension part 12 is clung to the oral cavity, the hand is clung to the included angle between the extension part 12 and the middle part, the hand can play a supporting role, and the stability is better during operation. In order that the medical staff can grip the middle part 11 more tightly and make the handle 1 not easy to slide from the hand, a plurality of anti-slip lines 111 are arranged on the outer surface of the middle part 11 in the embodiment. The friction between the middle part 11 and the hand can be increased by arranging a plurality of anti-slip lines 111 on the outer surface of the middle part 11, so that an anti-slip effect is achieved.

Specifically, the length a of the two extension parts 12 is 7cm, the width b is 2cm, and the thickness is 0.1cm; the length c of the intermediate portion 11 was 3cm, the width d was 2cm, and the thickness was 0.1cm. When the extraction of the vital teeth of the oromaxillofacial surgery is performed, the intermediate portion 11 is held to tightly attach one of the extension portions 12 to the lip corners, and at the same time, the retractor portion 2 fixes and pulls the tissue flap. The stability of the tissue flap can be ensured by the force of the angle of the mouth, and the medical staff can fully pull the oral view of the patient by using smaller force through the extension part 12, and because of more soft tissues in the oral cavity, the two ends of the handle 1 in the width direction are extended to the thickness direction to form the first bending part 13 in order to prevent the accidental scratch of the oral cavity of the patient, and the middle part 11 and the two extension parts 12 are covered by the first bending part 13. The two first bending parts 3 extend to opposite sides from one end of the handle 1 to form a first bending part 131. After the extension part 12 stretches into the oral cavity in use, the contact area between the extension part 12 and the oral cavity is increased by arranging the first bending part 13 and the first bending part 131, and the oral cavity is prevented from being scratched by a sharp included angle formed by the outer edge surface of the extension part 12.

With continued reference to fig. 6, in this embodiment, the number of the hook portions 2 is two, and the two hook portions 2 are respectively disposed on the two extension portions and are respectively disposed at one end of the two extension portions away from the middle portion for convenience. Because the two ends of the handle 1 have the same structure, medical staff can use any end to perform operation when in use, and the operation is more convenient. Meanwhile, in order to better enter the gingiva to turn over the flap and remove the bone, in the embodiment, the shape of the drag hook part 2 is in a flake shape, the thickness of the drag hook part 2 gradually decreases from the side close to the extension part 12 to the side far away from the extension part 12, so that the head of the drag hook part 2 is lighter and thinner, and because a certain gap exists between the gingiva and the teeth, the head of the drag hook part 2 is lighter and thinner, so that the drag hook part 2 enters the gap between the teeth and the gingiva, and the head of the drag hook part 2 is stronger in extensibility. Because the tooth surface and the inner surface of gum all have certain cambered surface, in order to make the better laminating tooth of drag hook portion and gum shape, drag hook portion 2 is the arc and to thickness direction crooked to this makes the surface of drag hook portion 2 form in the cambered surface that tooth and gum are laminated mutually, can let drag hook portion 2 more complete entering gum inside during the use. In order to form protection when in use, the bending direction of the drag hook part 2 is opposite to the extending direction of the first bending part 13, when the drag hook part 2 is used, an arc surface is required to be attached to teeth and gums, and when the arc surface formed by the drag hook part 2 is attached to teeth and gums, the first bending part 13 is opposite to the bending direction of the drag hook part 2, so that the first bending part can form protection to the oral cavity.

Example two

Referring to fig. 7, the difference between the present embodiment and the first embodiment is that: the angle between the two extensions 12 and the intermediate portion 11 is set to be less than 90 degrees. The extension 12 is formed to extend in the vertical direction at both ends of the intermediate portion 11, so that the extension 12 has a Z-like structure as a whole with the intermediate portion 11. During the use, medical staff grips middle part 11, with extension 12 and drag hook portion 2 visit in the oral cavity, when extension 12 hugs closely the oral cavity angle, simultaneously hand and extension 12 and middle part 11's contained angle department hugs closely, because middle part 11 and extension 12's contained angle is less than 90 degrees, middle part 11 and extension 12 can both play the supporting role to the hand this moment, because the angle is less, middle part 11 and extension 12 can be tighter to the centre gripping degree of hand for the hand is difficult for slipping out from between extension 12 and the middle part 11, can guarantee that stability is better when the operation. At the same time, one of the extending parts 12 can be held by the hand, so that the middle part 11 can be propped against the hand to form a support.

The foregoing is merely exemplary of the present utility model, and specific structures and features that are well known in the art are not described in detail herein. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present utility model, and these should also be considered as the scope of the present utility model, which does not affect the effect of the implementation of the present utility model and the practical applicability of the present utility model.
