[0001] The utility model relates to the technical field of medical devices, in particular to an oral retractor set. Background Art

[0002] Oral retractors are commonly used in oral surgery, primarily for retracting soft tissue to provide an adequate surgical field of view. However, existing retractors are relatively simple in design, not suitable for all patients' maxillary facial structures, and may require high pressure during surgery, increasing pain and the risk of complications.

[0003] To address these issues, customized oral retractors can be created through 3D printing technology. Chinese patent CN 219480200U discloses an oral retractor manufactured using 3D printing technology. Made of photosensitive resin, the retractor can be individually designed based on the patient's oral model, improving surgical efficiency and reducing patient discomfort. However, the strength of photosensitive resin is insufficient for long, high-intensity surgeries, which can easily cause the retractor to slip, increasing surgical risks. Utility Model Content

[0027] Example 1

[0028] The oral retractor kit disclosed in this embodiment includes:

[0029] See also Figure 1 The hook head 1 includes a front surface and a back surface 3. The front surface is configured as an arc surface. The back surface 3 is connected with a connecting section 4. The connecting section 4 extends away from the back surface 3.

[0030] The end of the connecting section 4 is connected to the handle structure through the bent portion 5.

[0031] The front surface is used to abut against the outer surface of the maxilla, and the curvature of the arc surface of the front surface is adapted to the curvature of the maxilla.

[0032] Specifically, the design of the retractor head 1 includes a front and a back 3. The front is constructed as an arc-shaped curved surface, which helps to abut against the outer surface of the maxillary bone, and its curvature can adapt to the curvature of the maxillary bone, thereby providing better fit and stability during surgery. The back 3 of the retractor head 1 is connected to a connecting section 4, which extends from one side of the back 3, so that the retractor head 1 can be firmly connected to the handle structure, and the length of the connecting section 4 can support the tissue without blocking the surgical field of view. The end of the connecting section 4 is connected to the handle structure through a bend 5. This design allows the retractor head 1 to adjust its angle and position as needed during surgery to adapt to different surgical requirements and the patient's anatomical structure.

[0033] During use, the front curved surface of the retractor head 1 abuts against the outer surface of the maxillary bone, utilizing its adaptive curvature to provide a stable pulling effect during surgery. Furthermore, through the connection between the bending portion 5 and the handle, medical staff can flexibly adjust the position of the retractor head 1 to ensure that the surgical area is fully exposed.

[0034] The material of the retractor head 1 is not limited to medical grade stainless steel, such as 316L; medical grade titanium alloy, such as Ti-6Al-4V, to ensure its durability and corrosion resistance and comply with the safety standards of medical equipment.

[0035] In this embodiment, the back surface 3 of the hook head 1 is configured as another arc surface.

[0036] The back surface 3 of the retractor head 1 is designed as another arc surface, which can fit the human tissue without increasing the pain of the patient.

[0037] The front surface of the retractor head 1 is a curved surface that conforms to the maxillary bone. This provides excellent support for the entire maxillary bone when the retractor is inserted, reducing the intensity of applied pressure. Furthermore, a connecting section 4 is attached to the back surface 3 of the retractor head 1 and connected to the handle structure via a bent portion 5, acting as a lever. This allows the retractor head 1 to pull tissue easily and effortlessly, reducing pain for the patient and the risk of complications. This simple structure is suitable for large-scale production applications.

[0038] Example 2

[0039] See also Figure 1 In this embodiment, both side ends of the hook head 1 are hooks, and the hook structure is an arc end 10.

[0040] Specifically, in order to avoid causing damage to the patient's oral tissue, the hook is designed to be a smooth arc shape, and the distance between the centers of the two hook arcs is called the center distance.

[0041] Example 3

[0042] See also Figure 1 In this embodiment, the bending portion 5 is an L-shaped connector, one end of the L-shaped connector is connected to the connecting section 4, and the other end is connected to the handle structure.

[0043] In this embodiment, the L-shaped connector is a key connecting component between the retractor head 1 and the handle structure. It has a unique geometric shape, with one end connected to the connecting section 4 and the other end connected to the handle structure.

[0044] The corners of the L-shaped connector are not traditional right angles, but arc corners. This design can reduce stress concentration and improve the stability and durability of the structure.

[0045] The connecting section 4 and the L-shaped connector are flat surfaces formed in one piece. This design simplifies the manufacturing process and, because it is formed in one piece, ensures the firmness of the connection and the overall coordination.

[0046] During surgery, the doctor can operate the L-shaped connector through the handle structure to control the position and angle of the retractor head 1.

[0047] The arc corner design provides a smooth transition, allowing the retractor head 1 to be adjusted more flexibly and reducing damage to surrounding tissues.

[0048] The design of rounded corners and integrated flat surface is not only beautiful, but also provides better structural strength and durability.

[0049] The surface of the L-shaped connector can be designed with special textures or coatings to provide better grip and anti-slip performance.

[0050] Example 4

[0051] See also Figure 1 To further illustrate the handle structure, this embodiment discloses that the handle structure includes a connecting rod 7 , one end of the connecting rod 7 is connected to the bending portion 5 , and the other end is connected to a grip 8 .

[0052] Specifically, the connecting rod 7 is used to transmit force and torque. One end of the connecting rod 7 is connected to the end of the L-shaped connector. The other end of the connecting rod 7 is connected to a handle 8. The handle 8 can be round, oval, or other ergonomic shapes to accommodate the gripping habits of different medical staff. The surface of the handle 8 can have an anti-slip texture or coating to increase friction with the user's hand and prevent slipping during use. In addition, the handle 8 can be designed to be adjustable to accommodate hands of different sizes.

[0053] The length of the connecting rod 7 can be adjusted according to surgical requirements and user preferences to ensure comfort and effectiveness of the operation.

[0054] In this embodiment, the cross-sectional area of ​​the connecting rod 7 gradually decreases along the direction away from the handle 8. The cross-section of the connecting rod 7 is an octagon.

[0055] Specifically, the cross-sectional area of ​​the connecting rod 7 gradually tapers from one end connected to the bending portion 5 to the other end connected to the handle 8. This design can reduce the weight of the connecting rod 7 while maintaining sufficient strength.

[0056] The connection between the connecting rod 7, the bending portion 5 and the handle 8 can adopt an integrated molding technology to ensure the firmness and integrity of the connection and avoid loosening or breaking during use.

[0057] The handle 8 is located at the other end of the connecting rod 7 and is designed to be suitable for the doctor's hand shape. The surface can have an anti-slip texture or coating to ensure a stable grip during surgery.

[0058] During use, the doctor can operate the connecting rod 7 through the handle 8, thereby controlling the position and angle of the retractor head 1 to achieve effective traction and exposure of the surgical area.

[0059] In this embodiment, the handle includes a handle body, and the handle body is provided with a first opening 13 and a second opening 14 along its length. The first opening 13 is for inserting the thumb, and the second opening 14 is for inserting other fingers.

[0060] Specifically, the handle is designed based on the natural shape of the human hand to provide a comfortable fit when gripped. The length, width, and shape of the handle are carefully designed to accommodate different hand sizes.

[0061] A first opening 13 is provided along the length of the handle, which is specially designed for the thumb to be inserted into. The size and shape of the opening take into account the comfort and stability of the thumb.

[0062] In addition to the first opening 13, a second opening 14 is provided to accommodate other fingers, typically the index finger, middle finger, and ring finger. The design of the second opening 14 helps these fingers easily insert and grip the handle, providing additional stability and control.

[0063] These openings are designed with ergonomics in mind, ensuring that the user's hands do not feel fatigued or uncomfortable when using the handle for extended periods of time. By properly positioning the fingers, hand muscle tension can be reduced, improving user comfort.

[0064] The positions and designs of the first opening 13 and the second opening 14 are intended to ensure that the user can naturally distribute force when operating the handle while maintaining flexibility and accuracy of the operation.

[0065] The surface of the handle can also be designed with an anti-slip texture or coating to increase friction with the medical staff's hands and prevent slipping during use.
