Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of corner hooks, and in particular to a corner hook. Background Technology
[0002] When examining and photographing teeth inside the mouth, a corner retractor is needed. Publication number CN221331293U discloses a corner retractor with lubrication function, relating to the field of dental medical device technology. It includes: a retractor body, a handle, and a lip groove. A portion of the retractor body is in contact with the teeth and gums, and the overall cross-section of the retractor body is U-shaped. The handle is located on the side opposite to the part of the retractor body in contact with the teeth and gums, and the handle is a flattened structure with gradually increasing thickness. The lip groove is the inner surface of the retractor body, and a hollow sac is provided on the surface of the lip groove. Lubrication holes are evenly distributed on the surface of the hollow sac that abuts against the corner of the lip. These lubrication holes, when squeezed, release lubricating fluid to lubricate the skin at the corner of the lip. However, when using a traditional corner retractor to take a photograph of the upper or lower jaw with the mouth open, it obstructs the view and fails to fully open the corner of the mouth, thus failing to fully lift the entire upper or lower lip to expose the vestibule. Improvements are needed. Utility Model Content
[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.
[0004] The present invention adopts the following technical solution: a corner hook, including a pull head, one end of which is fixedly connected to a handle, a lip groove and a corner groove are formed on the surface of the pull head, a protrusion is fixedly installed on the handle, a card is fixedly connected to the upper end of the pull head, and a hanging groove is formed at the end of the handle.
[0005] Preferably, the surface of the zipper pull has a lip groove, and the surfaces of the lip groove and the corner groove have a 1 / 4 arc design, while the edges of the zipper pull have a rounded corner design. This design allows the 1 / 4 arc shape to better fit the edge of the lips, thereby reducing discomfort.
[0006] Preferably, the card has rounded edges and a length of 5mm. This design allows the pull tab to fully lift the upper or lower lip without scratching the inside of the mouth.
[0007] Preferably, the zipper pull and the card are made of titanium alloy. This ensures that the titanium alloy will not leach substances harmful to the human body and is less prone to scratches and bacterial growth.
[0008] Preferably, the handle is designed to be wider at both ends and narrower in the middle, with a slightly curved shape and the surface of the raised dots being arc-shaped. This unique handle shape enhances the grip during use, the slightly curved design better conforms to facial curves and reduces patient discomfort, and the arc-shaped raised dots provide anti-slip properties while minimizing discomfort during holding.
[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0010] 1. In this utility model, the pull head, handle, and lip groove enable a clear view of the inside of the mouth and jaw when the lips are pulled, remove the obstruction of the corners of the mouth, and can completely pull up the entire upper or lower lip.
[0011] 2. In this utility model, the special shape of the handle makes the device more in line with the facial curve, reducing patient discomfort when stretching, while the protrusions on the handle increase the grip and make it easier to pull. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0019] Example 1
[0020] Please see Figs. 1-3This utility model provides a technical solution: a corner puller, including a pull head 1, one end of which is fixedly connected to a handle 2, allowing the pull head 1 to move via the handle 2. A lip groove 3 is formed on the surface of the pull head 1, allowing the pull head 1 to fix the lips through the lip groove 3. A corner groove 6 is formed on the surface of the pull head 1, allowing the pull head 1 to pull the corners of the mouth. A protrusion 4 is fixedly installed on the handle 2 to prevent slippage during gripping. A card 5 is fixedly connected to the upper end of the pull head 1. A hanging groove 7 is formed at the end of the handle 2, allowing the device to be hung up to save space and for convenient disinfection. After drying, the surface of the pull head 1 has a lip groove 3. The surfaces of the lip groove 3 and the corner groove 6 are designed with a 1 / 4 arc shape. The edge of the pull head 1 is designed with rounded corners, so that the 1 / 4 arc shape fits the edge of the lips better, thereby reducing discomfort. The edge of the card 5 is designed with rounded corners. The length of the card 5 is 5mm, so that the pull head 1 can completely lift the entire upper or lower lip. The rounded corner design will not scratch the inside of the mouth. The pull head 1 and the card 5 are made of titanium alloy, so that the titanium alloy material will not leach substances harmful to the human body and is not easy to scratch and breed bacteria.
[0021] Example 2
[0022] Please see Figs. 1-3 The handle 2 is designed to be wider at both ends and narrower in the middle, with a slight arc shape. The surface of the raised point 4 is also arc-shaped. This special shape design of the handle 2 enhances the grip during use, and the slight arc shape better conforms to the facial curves, reducing patient discomfort. The arc-shaped raised point 4 provides anti-slip properties while reducing discomfort during holding.
[0023] Working principle: During operation, the operator holds the handle 2 and inserts the card 5 into the lips. The handle 2 drives the pull head 1 to move. The 1 / 4 arc-shaped lip groove 3 on the pull head 1 fits tightly against the edge of the lips, and the corner groove 6 is close to the corner of the mouth to reduce discomfort and effectively lift the entire upper or lower lip. The design of the lip groove 3 not only fits but also ensures the comfort of operation. The 5mm long card 5 fixed at one end of the pull head 1 ensures that the hook can fully lift the lips, providing a clear intraoral and occlusal field of vision and removing the obstruction of the corner of the mouth. At the same time, the titanium alloy material of the pull head 1 and the card 5 ensures the safety of use and will not release substances harmful to the human body. Its scratch-resistant properties reduce the possibility of bacterial growth. The protrusions 4 on the handle 2 enhance the user's grip and make it easy to apply force without causing discomfort due to prolonged holding. The micro-arc structure of the handle 2 conforms to the facial curve and reduces the discomfort to the patient when stretching.
[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
