Description

Technical Field

[0001] The utility model belongs to the technical field of oral medical instruments, and in particular relates to a unilateral mucosal retractor with an auxiliary moisture-isolating function. Background Art

[0002] Moisture isolation is a crucial part in the diagnosis and treatment of oral diseases, such as composite resin filling treatment, molding and bonding of restorations, etc. In clinic, moisture isolation is often achieved with the help of aspirators, cotton rolls, cotton balls or rubber dams. However, for some patients with high muscle tension or shallow vestibular grooves, the cotton rolls or cotton balls are prone to displacement when used for buccal moisture isolation, which increases the difficulty of moisture isolation. In addition, muscle tension makes it difficult to pull the buccal mucosa apart, greatly increasing the risk of mucosal damage during the operation.

[0003] An opener is a device used to open the soft tissue of the upper and lower lips, and is often used in oral treatment. The current bilateral opener requires pulling both corners of the mouth at the same time, which makes it difficult for the patient to close the mouth, and the comfort level is poor. At the same time, it cannot help to isolate moisture. The unilateral opener requires the patient to bite by himself, and the patient cannot close his mouth during operation. It is not suitable for patients with obvious pharyngeal reflex or patients with poor cooperation (such as children), and it also cannot help to isolate moisture. CN219070225U discloses a unilaterally supported opener with lighting and saliva suction tube function, including: an opening forceps body; a bite mechanism, which is arranged on the outside of the opening forceps body head, and there are two bite mechanisms, which are used to open the teeth; a tongue pushing mechanism, which is arranged on one side of the bite mechanism and is used to fix the tongue after the bite mechanism opens the teeth. This patent cannot solve the above technical problems. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a unilateral mucosal retractor with an auxiliary moisture-proof function to solve the deficiencies in the prior art.

[0005] In order to achieve the above object, the utility model is implemented by the following technical solutions:

[0006] A unilateral mucosal retractor with an auxiliary moisture-isolating function is provided, comprising a retractor body and an auxiliary moisture-isolating plate, wherein the retractor body is in a "U" shape with two head ends, a lip groove is provided on the outer side of the middle part of the retractor body, and the auxiliary moisture-isolating plate is in the shape of a long plate. When the retractor body is clamped on one side of the lip, the two head ends of the retractor body are opposed to each other up and down, one end of the auxiliary moisture-isolating plate is connected to the inner side of any head end of the retractor body, and can be temporarily stopped at any position of the sliding path of the lip groove.

[0007] As described in the unilateral mucosal retractor with auxiliary moisture-proof function, the facing end surfaces of the two head ends of the retractor body are respectively provided with arc-shaped slide grooves distributed along the extension direction of the head ends, and one end of the auxiliary moisture-proof plate is provided with a slide ball adapted to the arc-shaped slide groove.

[0008] As described in the unilateral mucosal retractor with auxiliary moisture-isolating function, a connecting rod is provided between the sliding ball and the auxiliary moisture-isolating plate, and the auxiliary moisture-isolating plate changes the distance from the gingival mucosa by rotating the connecting rod.

[0009] As described in the unilateral mucosal retractor with auxiliary moisture-isolating function, both ends of the auxiliary moisture-isolating plate are arc-shaped.

[0010] As for the unilateral mucosal retractor with auxiliary moisture-proof function, the lip groove is a through groove running through the two head ends of the retractor body, and the extended area of ​​the side wall of the lip groove attached to the outside of the cheek is larger than the extended area of ​​the side wall attached to the inside of the oral cavity.

[0011] The beneficial effects of the technical solution of the utility model are:

[0012] While pulling the buccal mucosa, it can increase the retention of cotton rolls or cotton balls to assist in moisture isolation. The auxiliary moisture isolation plate is moved to the position of the affected tooth. Because the plate body forms a certain angle with the gingival mucosa, it can prevent the cotton rolls or cotton balls from falling off, thereby achieving the purpose of auxiliary moisture isolation. It is easy to disassemble and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 1 , Figure 2a , Figure 2b and Figure 3 As shown, the unilateral mucosal retractor with auxiliary moisture-proof function of the utility model comprises a retractor body 1 and an auxiliary moisture-proof plate 2. The retractor body 1 is in a "U" shape with two head ends 101. A lip groove 102 is provided on the outer side of the middle part of the retractor body 1. Similar to the use of an oral opener, the retractor body 1 is clamped on either side of the lip through the lip groove 102. The auxiliary moisture-proof plate 2 is in the shape of a long plate. When the retractor body 1 is clamped on one side of the lip, the two head ends 101 of the retractor body 1 are opposite to each other up and down. One end of the auxiliary moisture-proof plate 2 is connected to the inner side of any head end 101 of the retractor body 1, and can be temporarily stopped at any position of the sliding path of the lip groove. The position of the upper gingival mucosa corresponds to the upper head end of the retractor body 1, and the position of the lower gingival mucosa corresponds to the lower head end of the retractor body 1.

[0023] In a preferred embodiment, continue to refer to Figure 1 , Figure 2a , Figure 2bAs shown, the facing end faces of the two head ends 101 of the retractor body 1 are respectively provided with arc grooves 103 distributed along the extension direction of the head end 101, and one end of the auxiliary moisture-proof plate 2 is provided with a sliding ball 201 adapted to the linear groove 103, and the curvature of the groove is set along the curvature of the opener. It can be understood that the sliding ball 201 can be stopped at any position of the sliding path in the linear groove 103 by matching the materials (properly increasing the friction force), such as plastic-rubber, or rubber-rubber, etc. At this time, the outer diameter of the sliding ball 201 can be slightly larger than the slot width of the groove, and a certain angle is formed between the extension direction of the auxiliary moisture-proof plate 2 and the extension direction of the linear groove 103 while stopping.

[0024] Furthermore, a connecting rod 202 may be provided between the sliding ball 201 and the auxiliary moisture barrier 2 to enhance the stability of the auxiliary moisture barrier 2 after it is stopped. The auxiliary moisture barrier 2 may be brought close to the gingival mucosa above the affected tooth by the rotation of the connecting rod 202 .

[0025] See also Figure 2a , Figure 2b As shown, both ends of the auxiliary moisture barrier 2 are arc-shaped to avoid damage to the oral cavity lining. It is easy to understand that the body of the auxiliary moisture barrier 2 may have a certain small arc near the gingival mucosa to make it fit the gingival mucosa more closely.

[0026] See also Figure 1 As shown, the lip groove 102 is a through groove that passes through the two head ends 101 of the retractor body 1. Generally speaking, the extended area of ​​the side wall of the lip groove 102 attached to the outside of the cheek is larger than the extended area of ​​the side wall attached to the inside of the oral cavity.

[0027] In terms of size, the auxiliary moisture-proof plate 2 is about 20 mm long, the linear slide 103 is about 10-30 mm long, the depth is about 1 mm and does not exceed 1.5 mm, and the total height of the retractor body 1 when in use is about 25-35 mm and 14-15 mm wide.

[0028] When using, see Figure 3 As shown, the retractor body 1 is clamped on one side of the lips, and one end of the auxiliary moisture-proof plate 2 is detachably slidably connected to the inner side of any head end 101 of the retractor body 1 and can be temporarily stopped at any position of the sliding path. By rotating the connecting rod, the auxiliary moisture-proof plate 2 can be close to the gingival mucosa above the affected tooth.

[0029] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
