Description

Technical Field

[0001] The invention relates to a surgical instrument, in particular to an oral retractor used in oral treatment. Background Art

[0002] In many oral treatment processes, the gingival tissue needs to be pulled. For example, during the implant process, the lingual tissue flap needs to be pulled to expose the surgical field of view; in the periodontal subgingival cleaning process, in order to observe the subgingival state, the gingival tissue also needs to be separated and pulled outward to facilitate observation of the subgingival state. In these intraoral treatment processes, oral retractors are required to pull the tissue. Since the lingual tissue and operating space are significantly different from the buccal tissue and operating space, oral retractors need to be divided into lingual retractors and buccal retractors according to different working parts.

[0003] Since the oral treatment site is usually located under the tissue, after using the oral retractor for pulling, in order to observe the treatment site, the commonly used method is to use the reflection of the oral mirror to observe the subgingival area. Therefore, in oral treatment, doctors need to use both hands at the same time to expose and observe the treatment or surgical site, and different retractors need to be replaced when pulling the lingual and buccal tissues. The clinical operation is cumbersome, especially for young doctors with no experience, which increases the clinical difficulty.

[0004] Therefore, the purpose of the present application is to improve the existing oral retractors and realize the effective integration of the functions of the lingual retractors, buccal retractors and oral mirrors to meet different clinical needs and simplify clinical operations. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the oral retractor and the mouth mirror need to be operated by both hands at the same time during the existing oral treatment process. The functions of the oral retractor and the mouth mirror are integrated, especially the lingual oral retractor and the buccal oral retractor are also integrated at the same time to meet different clinical needs and simplify clinical operations.

[0006] The mirror-surface oral retractor of the present invention is characterized in that: the mirror-surface oral retractor 100 comprises a retractor 1, an observation mirror 2, and a handle 3;

[0007] A. The retractor 1 and the observation mirror 2 are arranged on the distal end of the handle 3;

[0008] B. The observation mirror 2 is arranged at the proximal end of the working part 11 of the retractor 1. The front side 21 of the observation mirror 2 is a mirror surface for observing the treatment operation area. The back side 22 of the observation mirror 2 blocks the tongue, and / or buccal, and / or gingival tissue from entering the operation area, thereby playing a protective role.

[0009] The retractor 1 and the observation mirror 2 can be manufactured as a whole. During use, the working part 11 of the retractor 1 penetrates deep into the subgingival or tissue to separate, pull and fix the tissue. The mirror surface 21 of the observation mirror 2 observes the treatment area. The back surface 22 of the observation mirror 2 can become a protective baffle to block the tongue, and / or cheek, and / or gum tissue from entering the operation area, thereby playing a protective role. The mirror oral retractor of the present invention has the functions of an oral retractor and a mouth mirror. The doctor can operate it with one hand during use, which is very convenient for clinical use. In addition, the baffle function of the observation mirror 2 can prevent accidental injury caused by accidental entry of tissue into the operation area during clinical treatment, making clinical use safer.

[0010] The working portion 11 of the retractor 1 can be designed into various shapes as needed. For example, when used as a gingival separator for subgingival cleaning, the working portion 11 can be designed into a sharp needle-like structure to facilitate penetrating into the subgingival cavity. When used for tissue flap during implantation, the working portion 11 can be designed into a thin plate-like design with a certain width, and can be designed with an anti-slip structure.

[0011] The observation mirror 2 can adjust the observation angle. The observation angle of the observation mirror 2 can be adjusted to meet the observation requirements of different treatment parts.

[0012] The viewing scope 2 is connected to the distal end of the handle 3 via a plastic connection unit 4, and the viewing angle of the viewing scope 2 can be changed by changing the spatial shape of the connection unit 4. The connection unit 4 can be made of a plastic material and structure such as a serpentine tube, and the angle can be manually adjusted directly as needed during clinical use, which is very convenient for clinical use.

[0013] The observation mirror 2 is detachably mounted on the handle 3. The observation mirror 2 can be detachably connected to the handle 3. During clinical use, the observation mirrors 2 of different sizes and directions and the retractors 1 of different functions such as the lingual side or the buccal side can be replaced as needed, and the clinical use is more widely applicable.

[0014] The front and back surfaces 22 of the observation mirror 2 are both mirror surfaces, forming a double-sided observation mirror 201. This double-sided observation mirror design can observe tissues on both sides at the same time without adjusting the direction of the observation mirror 2.

[0015] The two ends of the handle 3 are provided with the retractor 1 and the observation mirror 2 .

[0016] The retractor 1 comprises a lingual retractor 1-1 and a buccal retractor 1-2; the observation mirror 2 comprises a lingual observation mirror 2-1 and a buccal observation mirror 2-2; the two ends of the handle 3 are respectively provided with the lingual retractor 1-1 and the lingual observation mirror 2-1, and / or the buccal retractor 1-2 and the buccal observation mirror 2-2.

[0017] The handle 3 can be designed to be provided with the retractor 1 and the observation mirror 2 on both sides, and the retractor 1 and the observation mirror 2 at both ends can be combined and matched in various ways between the lingual retractor 1-1, the buccal retractor 1-2, the lingual observation mirror 2-1 and the buccal observation mirror 2-2 as needed to meet different clinical use needs.

[0018] During clinical use, the working portion 11 of the retractor 1 is used to separate and pull tissues to expose the working field, and when necessary, the working part is observed through the observation mirror 2 .

[0019] The mirrored oral retractor of the present invention comprises a retractor 1, an observation mirror 2, and a handle 3; the retractor 1 and the observation mirror 2 are arranged at the distal end of the handle 3; the observation mirror 2 is arranged at the proximal end of the working part 11 of the retractor 1, the mirrored part of the front 21 of the observation mirror 2 observes the treatment operation area, and the back 22 of the observation mirror 2 blocks the tongue, and / or cheek, and / or gum tissue from entering the operation area, playing a protective role.
