Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of corner traction devices, and more specifically, relates to a corner traction device. Background Technology
[0002] In lateral occlusal photography, currently available lateral occlusal corner retractors have certain limitations. They can only dissect the lip tissue but cannot fully dissect the buccal muscle mucosa and soft tissue, making it difficult to fully expose the patient's teeth, especially the complete occlusal relationship of the molars. Furthermore, the handle of existing retractors is relatively straight, requiring the photographer to raise their arm and exert force during the traction operation. This results in a lack of support for the hands, making stable and prolonged traction impossible and causing fatigue in the arms and hands of the photographer. This not only leads to poor patient comfort but also results in unsatisfactory photographic results, failing to meet clinical needs. Utility Model Content

[0008] Optionally, the cross-section of the tensioning sheet is semi-circular.
[0009] Optionally, the projection of the tensioning sheet is C-shaped, U-shaped, or V-shaped.
[0010] Optionally, the support angle is horn-shaped, the tip of the support angle is rounded, and the thicker end of the support angle smoothly transitions to the traction piece.
[0011] Optionally, the angle between the support angle and the traction piece is 135°.
[0012] Optionally, the handle is provided with an anti-slip layer.
[0013] Optionally, the tension sheet is a resin tension sheet.
[0014] Optionally, the handle is in the form of a sheet.
[0015] Optionally, the two ends of the contact groove are thickened.
[0016] Optionally, the handle is inclinedly disposed at the middle of the other side of the outer bend of the traction plate, symmetrically disposed with respect to the support angle.
[0017] This utility model provides a corner traction device, the advantages of which are:
[0018] This mouth corner puller is used by moving the puller with the handle. The puller fits against the corner of the mouth and pulls the corner of the mouth open. At the same time, the abutment opens the buccal muscle mucosa and soft tissue, so that the teeth are fully exposed and the lateral occlusion relationship can be fully displayed.

[0024] 1. Pulling plate; 2. Support angle; 3. Handle. Detailed Implementation
[0025] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0026] like Figure 1-2 As shown, a mouth corner puller includes:
[0027] The tension piece 1 is arc-shaped and has a contact groove on its outer curved side;
[0028] Support angle 2 is located in the middle of one side of the outer curved side of the traction piece 1, which can stretch the cheek muscle mucosa and soft tissue.
[0029] Handle 3 is inclinedly set on the other side of the outer curved side of the traction piece 1, and the connection between handle 3 and traction piece 1 is a thumb support.
[0030] Specifically, the traction device is moved by the handle 3, and the traction plate 1 is attached to the corner of the mouth, thereby pulling the corner of the mouth open. At the same time, the fulcrum 2 opens the buccal muscle mucosa and soft tissue, so that the teeth are fully exposed and the occlusal relationship can be fully displayed in the lateral occlusion phase.
[0031] In this embodiment, the cross-section of the tension piece 1 is semi-circular.
[0032] Specifically, it ensures comfort and prevents the corners of the mouth from slipping during traction.
[0033] In this embodiment, the projection of the tension piece 1 is C-shaped, U-shaped, or V-shaped.
[0034] Specifically, different shapes or sizes of traction devices are selected based on the shape and size of the oral cavity.
[0035] In this embodiment, the support corner 2 is horn-shaped, with a rounded tip and a smooth transition between the thicker end of the support corner 2 and the tension plate 1.
[0036] Specifically, the rounded corner 2 improves comfort and avoids sharp scratches.
[0037] In this embodiment, the included angle between the support angle 2 and the tension piece 1 is 135°.
[0038] Specifically, the thumb is bent at the right angle and connected to the traction plate 1 when holding handle 3, serving as the main fulcrum and point of force application. This allows the operator to place their weight on the gripping point between their thumb and forefinger when taking a lateral occlusal photograph to pull the corner of the mouth, using the support at the bend to pull the corner of the patient's mouth.
[0039] Furthermore, the twisting design of handle 3 allows the puller to have a center of gravity to leverage when pulling, enabling them to pull more effectively to the outside and back, thus reducing the puller's physical exertion.
[0040] In this embodiment, the handle 3 is provided with an anti-slip layer.
[0041] Specifically, the anti-slip layer prevents the handle 3 from slipping during rotation.
[0042] In this embodiment, the tension sheet 1 is a resin tension sheet.
[0043] Specifically, the traction sheet 1 is made of resin material that can withstand high temperature and high pressure sterilization. It is lightweight, low cost, and suitable for use as a disposable tool.
[0044] In this embodiment, the handle 3 is in the shape of a sheet.
[0045] Specifically, the sheet-like design ensures a stable grip and prevents slippage and rotation.
[0046] In this embodiment, the two ends of the contact groove are thickened.
[0047] Specifically, the thickened treatment ensures support strength and avoids sharp scratches on the edges.
[0048] In this embodiment, the handle 3 is inclinedly disposed at the middle of the other side of the outer bend of the traction piece 1, and is symmetrically disposed with the support angle 2.
[0049] Specifically, the positions of the support 2 and handle 3 are customized according to usage habits, with the standard being a symmetrical arrangement.
[0050] In this embodiment, a corner traction device is used, taking its application during a dental examination as an example:
[0051] Holding the handle 3, the traction piece is inserted into the corner of the mouth. The abutment 2 spreads the buccal muscle, mucosa, and soft tissue to pull the teeth. The center of gravity can be placed on the grip between the thumb and forefinger, using the support at the bend to pull the corner of the patient's mouth. Thus, when the operator pulls the corner of the mouth to take a lateral occlusal photograph, the molar relationship is fully exposed, ensuring that the photograph is completed quickly and smoothly, reducing patient discomfort.
[0052] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
