Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a cheek stop retractor used in wisdom tooth extraction surgery. Background Art

[0002] like Figure 1 As shown in the figure, wisdom teeth, also known as third molars, are the last teeth to erupt in the human mouth, usually starting to erupt between the ages of 17 and 25. They are located at the very end of the upper and lower jaws, that is, the last teeth in each quadrant. The presence and eruption of wisdom teeth vary from person to person. Not everyone will grow all four wisdom teeth, and some people may not have any, depending on genetic factors and personal development. The main function of wisdom teeth was to help humans chew rough foods such as unprocessed grains, nuts and meat in ancient times. With changes in dietary structure and the gradual reduction of the mandible during human evolution, the importance of wisdom teeth has been greatly reduced, and even become a "redundant" existence. Modern people's jaws often do not have enough space to accommodate these extra teeth, so wisdom teeth often cause a series of problems such as impaction, pain and discomfort. When wisdom teeth cause the above problems, dentists usually recommend extraction to avoid further health risks.

[0003] During wisdom tooth extraction, fully exposing the surgical site is the key to ensuring that the doctor has a clear field of vision, which is crucial to ensuring the safety and effectiveness of the operation. In traditional surgery, an assistant usually holds a W-shaped lip and cheek retractor (also known as a surgical retractor) on the patient's cheek, inserts the longer end into the patient's mouth to pull the corner of the patient's mouth apart, so as to better contact and operate the wisdom tooth located at the innermost part of the mouth (position 8).

[0004] However, the existing retractor design shows certain limitations in practical applications, especially when there is a large difference in the amount of cheek fat. For patients with less cheek fat, the existing retractor can effectively complete the task; but for patients with more cheek fat, the extra soft tissue is difficult to be effectively pushed away, which not only hinders the doctor's vision, but also may increase the difficulty and time of the operation, and may affect the surgical effect. Summary of the invention

[0005] The present invention is intended to provide a cheek retractor for wisdom tooth extraction surgery, so as to pull the buccal mucosa of the patient toward the cheek side, thereby exposing more visual fields and reducing the difficulty of the surgery.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a cheek stop retractor for wisdom tooth extraction surgery, comprising a first retractor body and a second retractor body for pulling the patient's cheek and an adjustment structure for maintaining the opening angle of the first retractor body and the second retractor body, the first retractor body is rotatably arranged in the middle of the second retractor body, the first retractor body and the second retractor body both include a cheek stop part and an operating part that are integrally formed and have a U-shaped structure, and the adjustment structure is arranged on the operating part and can limit the opening angle between the first retractor body and the second retractor body.

[0007] The beneficial effects of this solution are as follows: the present application uses an integrally formed U-shaped cheek stop and an operating part as the first hook body and the second hook body, and the first hook body is rotatably arranged in the middle of the second hook body, so that after the cheek stops of the first hook body and the second hook body are extended into the patient's mouth, under the action of the operating part, the cheek stops of the first hook body and the second hook body move away from each other, and under the action of the adjustment structure, the cheek stops of the first hook body and the second hook body maintain corresponding opening angles, thereby performing the first tensioning of the patient's mouth, and then, using the operating part, The operating part pulls the cheek stop toward the cheek of the patient for a second time to provide a larger exposure field of view, thereby reducing the difficulty of the operation; at the same time, since the first retractor body and the second retractor body of the present application are both U-shaped, when the surgical part is exposed, the operating part is bent toward the patient's face. When the patient is tensioned for the second time, the operating part can be hung on the medical staff's fingers or on a nearby frame, so that the medical staff does not need to pinch the retractor, thereby avoiding fatigue of the fingers due to long-term force. When the hook is hung on a nearby frame, the fingers of the medical staff can be further freed, which is more labor-saving.

[0008] Furthermore, the adjustment structure includes an arc-shaped rod and a pressure piece, wherein one end of the arc-shaped rod is fixed to the operating end of the first hook body, and the other end of the arc-shaped rod is slidably connected to the operating end of the second hook body. The pressure piece is arranged at the operating end of the second hook body and can limit the sliding of the arc-shaped rod and the operating end of the second hook body. Arc-shaped rod: one end is fixed to the operating end of the first hook body, and the other end is slidably connected to the operating end of the second hook body. This design allows an adjustable opening angle to be formed between the two parts to accommodate the oral cavity sizes of different patients. Pressure piece: arranged at the operating end of the second hook body, and can limit the sliding of the arc-shaped rod relative to the operating end of the second hook body. By adjusting the position or strength of the pressure piece, the opening angle between the two hooks can be precisely controlled to ensure stable tension during surgery.

[0009] Furthermore, it also includes a rotating shaft, and the first retractor body is rotatably arranged in the middle of the second retractor body through the rotating shaft. This design allows the first retractor body to rotate freely on the second retractor body, increasing the flexibility and adaptability of the device, so as to better fit the internal structure of the patient's oral cavity.

[0010] Furthermore, it also includes a tensioning auxiliary structure, which includes a locking piece and a pressing piece. The locking piece is fixedly connected to the rotating shaft, and one end of the pressing piece is fixed to the rotating shaft through the locking piece, and the other end is close to the cheek stop. The locking piece is fixedly connected to the rotating shaft and is used to fix one end of the pressing piece; the other end of the pressing piece is close to the cheek stop to form an additional support surface; when the pressing piece is fixed, it can help push the buccal mucosa more tightly to the cheek side, thereby providing a wider exposure field. Therefore, when the patient has too much fat on the cheek side, and only the two tensioning of the first retractor body and the second retractor body cannot meet the surgical exposure field, the pressing piece of the tensioning auxiliary structure can be used to tension the patient's buccal mucosa for a third time to obtain a wider exposure field.

[0011] Furthermore, a threaded hole is provided in the axial direction of the rotating shaft, and the locking piece is fixedly connected to the rotating shaft through the threaded hole. A threaded hole is provided in the axial direction of the rotating shaft, and the locking piece is fixedly connected to the rotating shaft through the threaded hole. This design not only simplifies the installation process, but also provides a firm and easy-to-adjust fixing method, ensuring stability during surgery.

[0012] Furthermore, the outer edge of the cheek guard is arc-shaped. The outer edge of the cheek guard adopts an arc-shaped design, which reduces the stimulation to the soft tissue in the oral cavity and improves the comfort of the patient, thereby preventing the cheek guard from scratching the patient's oral mucosa during the tensioning process.

[0013] Furthermore, the free end of the cheek guard portion approaches the free end of the operating portion to form a U-shaped structure. The free end of the cheek guard portion gradually approaches the free end of the operating portion, and finally forms a complete U-shaped structure. Such a design not only ensures sufficient opening space, but also facilitates gripping and ensures a good tensioning effect.

[0014] In combination with the above technical features, this application also includes the following technical effects:

[0015] 1. Enhance flexibility and adaptability: Through the design of the rotating part and the rotating shaft, the retractor can be flexibly adjusted in different directions and is suitable for various complex oral environments; 2. Improve stability: The combination of the adjustment structure and the tensioning auxiliary structure ensures the stability of the retractor position during the operation and avoids surgical errors due to accidental movement; 3. Increase patient comfort: The optimized design of the cheek stop reduces discomfort inside the oral cavity and reduces anxiety during the operation; 4. Reduce the burden on medical staff: Through clever ergonomic design, medical staff can maintain a relaxed working state during long operations, thereby improving overall work efficiency.

[0016] Further, the free end of the operating part approaches the free end of the cheek stop to form a U-shaped structure. The free end of the operating part approaches the free end of the cheek stop to form a U-shaped structure, so that the opening angle of the cheek stop of the first and second retractor bodies is larger, so that the exposed field of view is larger.
