Description

Technical Field

[0001] This application relates to the field of medical devices, and more specifically, it relates to a gingival retractor for dental surgery. Background Art

[0002] Most dental surgeries require retracting the gingiva to expose the surgical area. However, even after a good incision and flap elevation process, during the implementation of dental surgery, the free gingival soft tissue flap often causes more or less interference to the surgery. The free soft tissue during the operation still hinders the subsequent surgical procedures. At the same time, in some dental surgeries, high-speed instruments such as turbines need to be used during the operation, which has a high probability of causing irreversible damage to the free gingival flap and affecting the healing of the patient's postoperative wound. Since general surgical retractors or retractors cannot be used in the narrow oral cavity, currently, some small dental instruments (such as periosteal elevators, etc.) can only be used to replace the gingival retractor to retract the gingiva. There are also some operators who suture the gingiva to retract the gingiva. These above methods not only affect the surgical operation but also easily damage the gingiva.

[0003] Therefore, there is an urgent need in this field for a gingival retractor for dental surgery that can easily retract and fully protect the free gingival flap, so as to fully expose the surgical field, reduce the difficulty of surgical operation, facilitate the operation of the surgeon, save operation time, ensure the safety during the operation, and improve the intraoperative experience and postoperative efficacy of the patient. Summary of the Invention

[0004] The purpose of the present utility model is to provide a gingival retractor with a simple structure, convenient and efficient operation, and capable of fully retracting and protecting the free gingival flap.

[0005] This application provides a gingival retractor for dental surgery, adopting the following technical solutions:

[0006] A gingival retractor for dental surgery, comprising:

[0007] A gingival retractor for dental surgery, characterized by comprising:

[0008] A handle;

[0009] Two curved necks, which are respectively arranged at both ends of the handle; and

[0010] Two working heads, which are respectively arranged at the ends of the curved necks far away from the handle, and the working heads are used for separating and retracting the gingival flap;

[0011] The curved necks are 90° curved arcs and naturally transition to the working heads, which is conducive to the convenient and efficient insertion of the working heads between the buccal and lingual gingival flaps and the alveolar bone.

[0012] Optionally, the two working heads are paired in opposite directions.

[0013] Optionally, the main body part of the working head is in the shape of a trapezoid that is wider at the top and narrower at the bottom, which can fully stretch and protect the free gingival flap.

[0014] Optionally, the longitudinal section of the working head is an arc with a bending rate of 30°. During operation, the two arc-shaped working heads are inserted between the buccal and lingual gingival flaps and the alveolar bone.

[0015] Optionally, the handle is in the shape of a cylinder with a diameter of 2 mm, which is convenient for holding.

[0016] Optionally, the surface of the handle is provided with threaded protrusions, which have an anti-slip effect.

[0017] In summary, the present application has the following beneficial effects:

[0018] The gingival retractor for dental surgery of the present utility model has an anti-slip handle that is convenient to hold. The 90° bent necks at both ends of the handle are beneficial for the working head to be conveniently and efficiently inserted between the buccal and lingual gingival flaps and the alveolar bone. The main body part of the working head is in the shape of a trapezoid that is wider at the top and narrower at the bottom, and the longitudinal section of the working head is an arc with a bending rate of 30°. It separates and stretches the gingival flap, providing a safe space for surgical operation, thus facilitating the operation of the surgeon and fully protecting the gingival flap.

[0023] The following further details the structure and effects of the present application in conjunction with the embodiments. It can be understood that the specific embodiments described herein are only for explaining the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only the parts related to the present invention are shown in the drawings, rather than all the structures.

[0024] Embodiment

[0025] The embodiment of the present application discloses a gingival retractor for dental surgery. Refer to Figures 1-3, a gingival retractor for dental surgery includes a handle 1, two curved necks 2 arranged at both ends of the handle 1, and a working head 3 arranged at the end of the curved neck 2. The handle 1 is a cylindrical shape with a diameter of 2 mm, which is convenient for holding. And the surface of the handle 1 is provided with thread protrusions, which has an anti-slip effect. The curved neck 2 is an arc bent at 90° and naturally transitions to the working head 3, which is beneficial for the working head 3 to be inserted between the buccal and lingual gingival flaps and the alveolar bone conveniently and efficiently. The working head 3 is used for separating and retracting the gingival flap. Its longitudinal section is an arc with a bending rate of 30°. The two arc-shaped working heads 3 are inserted between the buccal and lingual gingival flaps and the alveolar bone. The main part of the working head 3 is a trapezoid with a wider upper part and a narrower lower part, and the two working heads 3 are paired in opposite directions, which can fully retract and protect the free gingival flap.

[0026] For a gingival retractor for dental surgery provided by the present utility model, during use, first perform routine anesthesia. After disinfecting and draping, make a sufficient incision and flap to expose the surgical area. Then hold the handle 1 of the gingival retractor by hand, insert the working head 3 between the buccal and lingual gingival flaps and the alveolar bone, separate and retract the gingival flap, so as to fully protect the gingival flap and facilitate the subsequent surgical operation.
