[0002] Impacted teeth are teeth that are partially or completely unable to erupt due to various reasons, and are unlikely to erupt normally in the future. If impacted teeth are not extracted in time, they can lead to a series of oral health problems, such as crowding and malocclusion, damage to adjacent teeth, and pericoronitis of the wisdom teeth. Some patients may also experience pain, inflammation, tooth loosening, and osteomyelitis of the jawbone, and in severe cases, even facial swelling and difficulty opening the mouth, significantly impacting the patient's quality of life. Therefore, early extraction of impacted teeth is crucial. However, in complex oral and maxillofacial surgeries, especially those requiring flap surgery, a clear surgical field is essential. While conventional surgical retractors can effectively pull tissue flaps and expose the surgical field, in practice, the edges of commonly used retractors are often sharp, easily causing pressure on the patient's gum tissue, leading to intraoperative pain and discomfort, thus increasing patient suffering and affecting surgical efficiency. Furthermore, existing retractors do not adequately consider patient comfort and operational stability when pulling tissues, and conventional tools have certain limitations in practical application.

[0024] like Figure 1 As shown, Figure 1This illustration shows a schematic diagram of a willow-leaf retractor for impacted tooth extraction in oral and maxillofacial surgery. The willow-leaf retractor includes a gripping part 1 and a retractor part 2. The gripping part 1 is willow-leaf shaped. The retractor part 2 includes a first retractor 21 and a second retractor 22, symmetrically arranged at both ends of the gripping part 1. The first and second retractors 21 and 22 are bent in the same direction, with a smooth transition at the connection between the first retractor 21 and the gripping part 1, and a convex shape at the connection between the second retractor 22 and the gripping part 1. The willow-leaf design of the gripping part 1 is ergonomic, reducing fatigue for surgeons during prolonged operation and enhancing tool stability. The symmetrical double-retractor design of the retractor part 2 allows for even force application at different surgical angles and positions, providing more precise traction. The first retractor 21 and the second retractor 22 are folded back in the same direction. The smooth transition and convex transition design at the connection point avoid the pressure of the sharp edges of traditional retractors on the patient's gums and soft tissues, reducing discomfort during the operation. This design ensures that the tool can effectively expose the surgical field in complex surgeries, improve operational precision, reduce patient pain, and enhance the safety and efficiency of the surgery.

[0025] Preferably, the total length of the willow leaf retractor for impacted tooth extraction in oral and maxillofacial surgery is 20 cm, and the maximum width of the gripping part 1 is 3.5 cm.

[0026] Preferably, the width of the first hook 21 is 1.2 cm and the width of the second hook 22 is 0.6 cm.

[0027] Preferably, the folding distance between the first hook 21 and the second hook 22 is 0.3 cm.

[0028] Preferably, such as Figure 2 As shown, the folding angles of the first hook 21 and the gripping part 1, and the second hook 22 and the gripping part 1, are both 15 degrees. This precise folding angle setting allows the hook part 2 to more stably pull tissue, exposing the surgical field, while reducing pressure on the gingiva and surrounding soft tissues during force application. The 15-degree folding angle design ensures that the tool provides ideal angle and force in various surgical environments, making surgical operations more precise and efficient, improving patient comfort, and avoiding intraoperative discomfort caused by improper angles.

[0029] Preferably, the angle formed at the connection point by the folding angle of the first hook 21 and the second hook 22 is 60 to 90 degrees.

[0030] Preferably, the first hook 21 and the gripping part 1, and the second hook 22 and the gripping part 1, are connected in a gradually curved manner, with a transition curvature of 10 to 20 degrees. This design makes the connection between the hook part 2 and the gripping part 1 smoother and more natural, avoiding sharp angles that may occur in traditional designs and reducing pressure on the patient's gums and soft tissues. The gradually curved transition curvature not only improves the comfort of operation during the procedure but also makes the tool more stable when pulling soft tissues, allowing for more effective exposure of the surgical area. By optimizing the transition curvature at the connection, the tool can adapt to different operational needs, providing more precise traction, thereby improving the safety and efficiency of the procedure while enhancing patient comfort.

[0031] Preferably, the surface of the grip portion 1 facing the palm is provided with an anti-slip texture. The anti-slip texture can effectively increase the friction between the grip portion 1 and the palm, preventing the hand from slipping during prolonged surgical operations, thereby reducing the risk of errors caused by the surgeon's unstable operation. Especially during high-intensity, delicate operations, the anti-slip texture can provide better control, allowing the surgeon to apply force more precisely and improving the comfort of using the tool.

[0032] Preferably, the edges of the first hook 21 and the second hook 22 are rounded.

[0033] Preferably, the first retractor 21 and the second retractor 22 are made of titanium alloy. The rounded edges allow the retractor portion 2 to gently pull tissue, reducing patient pain and intraoperative discomfort. Furthermore, the rounded edges enhance the tool's durability and safety, preventing accidental intraoperative injuries that could be caused by sharp edges, thus improving surgical comfort and precision. The method of use of this utility model is as follows:

[0034] First, the dentist accurately locates the surgical area based on the patient's oral condition and the location of the impacted tooth to be extracted. Then, the dentist grasps the handle of the willow-leaf retractor, ensuring a tight grip against the anti-slip texture for a stable feel. Next, depending on the surgical needs, either the first or second retractor is selected and inserted into the mouth, adhering closely to the soft tissue of the target area. By adjusting the angle and position of the retractor, the dentist can flexibly pull and expose the impacted tooth area, ensuring a clear field of vision and even traction force. The folded design and transitional curvature help to smoothly contact the gums and surrounding soft tissue, avoiding damage. After the procedure, the dentist removes the willow-leaf retractor, ensuring the surgical area is undamaged, and cleans and disinfects the tool. This method allows the willow-leaf retractor to provide precise traction, helping to complete complex impacted tooth extraction surgeries while ensuring patient comfort and surgical efficiency.
