With the gum inspection part 3, it is convenient for the doctor to flexibly conduct specular reflection observation. At the same time, the gum inspection work can be directly operated, which is convenient for the staff to test problems such as gum bleeding and gum covering depth. This structure does not require two-handed operation and is more suitable for use in a narrow oral cavity. It is inconvenient to manually hold a dental needle for operation. With the gum inspection part 3, the gum can be flexibly prodded, and the angle of the gum inspection part 3 can be conveniently controlled, which can improve the flexibility of this structure. When the gum inspection part 3 is inserted into the gum, it is convenient to adjust the angle of the oral mirror group 1 with one hand. After adjusting the angle, the position of the gum inspection part 3 can be quickly controlled with one hand to ensure that the specular reflection position can be flexibly adjusted, which is convenient for the staff to check the inner side of the gum and is also convenient for subsequent stable inspection of gum bleeding and other situations, which can improve the actual diagnosis and treatment efficiency of this structure. When it is necessary to adjust the observation angle of the frame 102, the oral mirror handle 101 can be held, and the detection column 302 is inserted into the gum. When the frame 102 is rotated, the inspection ball head 301 can be automatically adapted. When it is necessary to position the detection column 302, when the doctor controls the detection needle 303 to prod the gum, the index finger and thumb cooperate to rotate and pull back the threaded sleeve 105, pull back the ring 106, and tighten the connecting wire 204. At this time, the connecting wire 204 can pull the wound swing control stud 201 to rotate, so as to realize the close fitting of the pressing and fitting piece 202 to the inspection ball head 301 for positioning.;

[0040] As Figures 4 to 8 shown, the depth test piece 4 includes a waterproof sleeve 401 slidably sleeved on the upper part of the detection column 302; an electricity connection ring 402 is sleeved inside the waterproof sleeve 401, and the electricity connection ring 402 is sleeved on the detection column 302; the bottom of the waterproof sleeve 401 is fixedly sleeved on the detection column 302; there is air pressure between the waterproof sleeve 401 and the detection column 302, and the waterproof sleeve 401 is made of elastic rubber material; the detection column 302 is of an elastic steel column structure; the depth test piece 4 further includes a bottom electricity connection ring 403 fixedly installed on the detection column 302; the bottom electricity connection ring 403 is located outside the detection column 302; the bottom electricity connection ring 403 is aligned with the electricity connection ring 402; the electricity connection ring 402, the bottom electricity connection ring 403 and the indicator lamp 107 are connected in series with the power supply. With the depth test piece 4, the gum bleeding detection work can be carried out in real time, which can avoid continuing to press the detection needle 303 after the gum penetration depth has reached the standard, resulting in too large a penetration depth, directly affecting safety, and at the same time causing unnecessary damage. The periodontal pocket is the gap formed between the gum and the tooth. The depth of the periodontal pocket of healthy gums is usually between one and three millimeters. If the probing depth exceeds three millimeters, it indicates that there may be gum inflammation or periodontitis. The deepening of the periodontal pocket may be accompanied by alveolar bone resorption, further leading to tooth loosening. At the same time, this structure can realize automatic detection and alarm prompt, which is convenient for the staff to stop in time.

[0041] As Figures 4 to 10As shown, the safety detection component 5 includes a detection sleeve 501 fixedly installed on the inspection ball head 301; the detection sleeve 501 is located outside the detection column 302; a detection ring 502 is fixedly installed inside the detection sleeve 501; the detection ring 502 is located outside the detection column 302; there is a spacing between the outside of the detection column 302 and the detection ring 502; the detection sleeve 501 is a rigid cylindrical structure; the safety detection component 5 further includes a rubber sleeve 5011 fixedly installed on the top of the detection sleeve 501; the top of the rubber sleeve 5011 is sleeved on the detection column 302; the rubber sleeve 5011 is a soft rubber structure. With the safety detection component 5, when the staff uses the detection needle 303 to pick the patient's gums to observe the gums and tooth gaps, it can automatically provide anti-injury protection, which can improve the safety of this structure, avoid the problem that the doctor is likely to apply excessive picking force due to limited perception of the force by the hand during actual operation, the structure is more reasonable, and it can perform safety detection in real time. At the same time, this structure is not affected by the picking direction and can achieve detection.

[0042] The return compensation member 6 includes an electromagnet 601 fixedly installed on the oral mirror handle 101; the electromagnet 601 is electrically connected to the detection ring 502 and the detection column 302; a positioning column 602 is slidably installed on the oral mirror handle 101; a spring is provided between the electromagnet 601 and the positioning column 602; the positioning column 602 is used to slide inside the oral mirror handle 101; the electromagnet 601 is aligned with the positioning column 602; the return compensation member 6 further includes a bent push-out shaft 603 slidably installed on the oral mirror handle 101; a through groove is provided on the bent push-out shaft 603; a connecting wire 204 passes through the through groove on the bent push-out shaft 603; the positioning column 602 is inserted into the bent push-out shaft 603; when the bent push-out shaft 603 is inserted and positioned by the positioning column 602, the connecting wire 204 is guided to bend. By using the return compensation member 6, it can cooperate with the safety detection member 5, and can automatically perform control compensation work during the actual operation of the doctor. When the safety detection member 5 detects that the prodding force is too large, it can automatically control the release of the positioning of the inspection ball head 301. At this time, the detection needle 303 will be in a rotatable state. If the prodding force of the detection needle 303 is too large, the inspection ball head 301 will automatically rotate and adapt. At the same time, this structure can use the bent push-out shaft 603. During normal operation, the return pull threaded sleeve 105 can be maintained to control the tightening of the connecting wire 204. However, once there is a problem of excessive stress, it can automatically control the relaxation of the connecting wire 204. During the actual operation process, the connecting wire 204 is guided to bend by the through groove on the bent push-out shaft 603. If the pressure is too large when holding the detection needle 303 to prod the gums, the detection column 302 will be bent elastically and pressed against the detection ring 502. At this time, the detection ring 502 and the detection column 302 will energize the electromagnet 601, magnetically attract the positioning column 602, and the connecting wire 204 will be relaxed. At this time, under the extrusion of the torsion spring 203, the swing control stud 201 can rotate to release the extrusion and position the inspection ball head 301. At this time, the detection column 302 can be freely bent to prevent potential safety hazards caused by continuous prodding and pressure application.

[0043] The working principle provided by the present invention is as follows. First, the doctor holds the oral mirror handle 101 and inserts it into the patient's oral cavity, and observes through reflection by the lens on the frame 102. The gum can be examined by inserting the detection column 302 into the gum. At this time, if the observation angle of the frame 102 needs to be adjusted, the doctor can hold the oral mirror handle 101 and keep the detection column 302 inserted into the gum. When the frame 102 is rotated, the inspection ball head 301 can be automatically adapted. When it is necessary to position the detection column 302 and the doctor controls the detection needle 303 to pick the gum, the threaded sleeve 105 can be rotated and pulled back by the cooperation of the index finger and thumb, the pulling ring 106 is pulled, and the connecting wire 204 is tightened. At this time, the connecting wire 204 can pull the wound swing control stud 201 to rotate, so as to realize that the extrusion fitting piece 202 is tightly attached to the inspection ball head 301 for positioning. The operation is simple and convenient, and can be flexibly controlled. When the swing control stud 201 is loosened, the inspection ball head 301 is no longer squeezed and positioned, and the return spring 3011 can pull the inspection ball head 301 to reset elastically. When the detection needle 303 is inserted into the gum, once the depth is too large, the gum will squeeze the waterproof sleeve 401. When the waterproof sleeve 401 is squeezed, it will drive the electric connection ring 402 to fit the bottom power-on ring 403. At this time, the bottom power-on ring 403 controls the power-on of the indicator light 107 to give a lighting prompt; when the doctor holds the detection needle 303 to pick the gum and the pressure is too high, the detection column 302 will be bent elastically and pressed against the detection ring 502. At this time, the detection ring 502 and the detection column 302 will energize the electromagnet 601 to magnetically attract the positioning column 602. At this time, the positioning column 602 no longer inserts into the bending and pushing shaft 603. At this time, the tensioned connecting wire 204 is no longer limited and guided by the through groove of the bending and pushing shaft 603 and is bent, and the connecting wire 204 will become loose. At this time, under the extrusion of the torsion spring 203, the swing control stud 201 can rotate to release the extrusion and positioning of the inspection ball head 301. At this time, the detection column 302 can be freely bent to prevent injury during picking.
