[0036] To make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope protected by the present utility model.

[0037] Refer to Figures 1-5, a specific embodiment of the present utility model provides an adjustable retractor for simultaneously retracting the buccal and lingual gingival flaps and the lip tissue, including a retractor handle 8, and further including:

[0038] A lingual dissector 1, the first end of the lingual dissector 1 is fixedly connected to the first end of the retractor handle 8;

[0039] A buccal dissector 4, the first end of the buccal dissector 4 is detachably connected to the middle end of the retractor handle 8, and is disposed opposite to the lingual dissector 1;

[0040] A lip tissue retractor 5, the lip tissue retractor 5 is detachably connected to the retractor handle 8, and is located on the side of the buccal dissector 4 away from the lingual dissector 1.

[0041] At present, in oral clinical practice, the dissector can only retract the unilateral gingival tissue flap on the buccal or lingual side, and an oral mirror or an arch retractor is still needed to assist in retracting the lip tissue. In addition, the clinical assistant often needs to assist in oral saliva aspiration operation, resulting in it being difficult for a single assistant to complete the above operations simultaneously, or the surgical field of view being blocked due to excessive use of oral instruments. At present, there is no instrument in oral clinical practice that can simultaneously retract the buccal and lingual gingival tissue flaps and the lip tissue. In this application, the lingual dissector 1, the buccal dissector 4 and the lip tissue retractor 5 are combined on the retractor handle 8, which is beneficial for the assistant to hold this instrument with one hand during the implant surgery, and can simultaneously retract the buccal and lingual gingival tissue flaps and the lip tissue, which is beneficial for improving work efficiency and providing a clearer and wider surgical field of view for the implant surgery.

[0042] For a further optimized solution, it further includes:

[0043] A lingual surface clamping piece 2, the lingual surface clamping piece 2 is fixedly connected to the lingual dissector 1;

[0044] A buccal surface clamping piece 3, the buccal surface clamping piece 3 is fixedly connected to the buccal dissector 4, and is arranged in parallel with the lingual surface clamping piece 2, and the lingual surface clamping piece 2 and the buccal surface clamping piece 3 clamp on both sides of the tooth.

[0045] The lingual surface clamping piece 2 and the buccal surface clamping piece 3 are located between the lingual dissector 1 and the buccal dissector 4, which is beneficial for improving the stability of the dissector in retracting the gingival flap. In addition, when no one holds the retractor, the lingual dissector 1 and the buccal dissector 4 can be fixed (clamped) to the adjacent tooth by means of the lingual surface clamping piece 2 and the buccal surface clamping piece 3, which is convenient for the continuous exposure of the surgical field of view. Both the lingual dissector 1 and the buccal dissector 4 are of an arc design, and the outer shape is specially designed to be approximately L-shaped, which is convenient for stably retracting the gingival tissue flap by means of the adjacent tooth. Their working ends are both of an arc-shaped spoon design, which is beneficial for fully retracting the gingival tissue flap and will not cause compression or necrosis of the gingival tissue even after long-term use, improving the applicability and the patient's comfort, and at the same time increasing the function of fixed clamping based on the lingual surface clamping piece 2 and the buccal surface clamping piece 3.

[0046] The further optimized solution also includes:

[0047] Silicone protective sleeves 9, and two sets of silicone protective sleeves 9 are respectively sleeved at the clamping positions of the tongue surface clamping piece 2 and the buccal surface clamping piece 3.

[0048] The main purpose of installing the silicone protective sleeves 9 is to prevent damage to adjacent teeth when clamping teeth.

[0049] In the further optimized solution, the second end of the retractor handle 8 is set as a holding part 82, and the holding part 82 is fixedly connected to the middle end of the retractor handle 8 through a connecting part 81.

[0050] The holding part 82 is set as a retractor with an S-shaped design, which is more in line with human mechanics, is beneficial for the operator to hold the holding part 82 for a long time during the implantation, and will not cause damage to the lip and facial soft tissues of the patient.

[0051] The further optimized solution also includes:

[0052] Adjustment groove 10, and the adjustment groove 10 is opened on the retractor handle 8;

[0053] Buccal elevator fixing structure 6, the buccal elevator fixing structure 6 passes through the adjustment groove 10 and is slidably connected in the adjustment groove 10 along the direction of approaching or departing from the lingual elevator 1, and the buccal elevator 4 is fixedly connected to the retractor handle 8 through the buccal elevator fixing structure 6.

[0054] The adjustment groove 10 runs through the retractor handle 8 up and down. The buccal elevator fixing structure 6 slides in the adjustment groove 10 to adjust the distance from the lingual elevator 1, driving the buccal elevator 4 to move on the retractor handle 8. After moving to a suitable position, the buccal elevator 4 is fixedly connected to the retractor handle 8 through the buccal elevator fixing structure 6.

[0055] In the further optimized solution, the buccal elevator fixing structure 6 includes:

[0056] Fixing screw 61, and the threaded end of the fixing screw 61 penetrates into the first side of the adjustment groove 10;

[0057] Fixing nut 62, the fixing nut 62 passes through the buccal elevator 4 and also penetrates into the second side of the adjustment groove 10, and the fixing nut 62 is threadedly sleeved on the threaded end of the fixing screw 61.

[0058] The fixing nut 62 is a cap nut, and the diameter of its hemispherical top is larger than that of the hollow cylindrical part. The fixing nut 62 penetrates through the flaky top of the buccal dissector 4 and the adjusting groove 10 from bottom to top in sequence. Therefore, the buccal dissector 4 can be fixed below the adjusting groove 10 through the fixing nut 62. The top of the fixing screw 61 is designed with an internal hexagon, and its appearance is smooth, with better fastening performance and comfort. It penetrates through the adjusting groove 10 from top to bottom. The fixing nut 62 and the fixing screw 61 are dimensionally adapted and are connected by screwing. Moreover, their lengths are both shorter than the depth of the adjusting groove 10, which can ensure that there will be no obvious protrusions above and below the adjusting groove 10 when moving and / or fixing the buccal dissector 4, improving the comfort of the patient.

[0059] When the length after partial connection of the fixing nut 62 and the fixing screw 61 is equal to the sum of the depth of the top sheet of the buccal dissector 4 and the adjusting groove 10, the adjusting groove 10 fixes the position and angle of the buccal dissector 4 through the buccal dissector fixing structure 6. At this time, the operator can use the retractor to fix and pull the gingival flap and lip tissues.

[0060] When the length after partial connection of the fixing nut 62 and the fixing screw 61 is greater than the sum of the depth of the top sheet of the buccal dissector 4 and the adjusting groove 10, the buccal dissector fixing structure 6 and the adjusting groove 9 become loose. At this time, the position and angle of the buccal dissector 4 can be changed accordingly according to the width between the alveolar bones.

[0061] The further optimized solution also includes:

[0062] The retractor sheet limiting holes 7 are symmetrically arranged on both sides of the retractor handle 8 and are arranged in the direction of approaching or departing from the buccal dissector 4. The lip tissue retractor sheet 5 is clamped in two opposite groups of retractor sheet limiting holes 7.

[0064] The retractor sheet main body 51;

[0065] The retractor sheet fixing blocks 52, two groups of retractor sheet fixing blocks 52 are respectively fixedly connected to both sides of the retractor sheet main body 51 and are respectively clamped in the corresponding retractor sheet limiting holes 7.

[0066] By clamping the retractor sheet fixing blocks 52 of the lip tissue retractor sheet 5 with the retractor sheet limiting holes 7 at different positions, the retraction of lips with different thicknesses can be satisfied, increasing the comfort of the patient.

[0067] The position of the lip tissue retractor sheet 5 can be changed by replacing the retractor sheet limiting holes 7.

[0068] The further optimized solution also includes:

[0069] The working end 11 of the lingual dissector, the second end of the lingual dissector 1 is set as the working end 11 of the lingual dissector;

[0070] The working end 41 of the buccal dissector, the second end of the buccal dissector 4 is set as the working end 41 of the buccal dissector.

[0071] Both the working end 11 of the lingual dissector and the working end 41 of the buccal dissector are set as round heads, which can effectively avoid causing harm during use, improving applicability and patient comfort.

[0072] During use, hold the S-shaped tail of the retractor handle 8 with one hand. Outside the mouth, first, according to the width of the alveolar bone and the thickness of the lip tissue in the patient's mouth, after loosening the fixing screw 61, change the position and angle of the buccal dissector 4 in the adjustment slot 9. After adjusting to the appropriate position, tighten the fixing screw 61, and then select different pull sheet limit holes 7 to change the position of the lip tissue pull sheet 5. Pull the buccal dissector 4 and the lingual dissector 1 respectively at the buccal and lingual gingival flaps, and use the lingual clamping piece 2 and the buccal clamping piece 3 of the adjacent tooth to play a role in fixing and clamping. At the same time, the lip tissue pull sheet 5 can fully pull apart the buccal and labial tissues, fully exposing the alveolar bone conditions in the surgical area. The operator only needs one hand to complete the pulling of the buccal and lingual gingival flaps and the lip tissue, and the other hand can assist the surgeon to complete other operations.
