Description

Technical Field

[0001] The present invention relates to the technical field of oral medical instruments, and particularly relates to an oral mirror with multi-angle adjustment. Background Art

[0002] Oral medicine refers to the prevention, diagnosis and treatment of oral and maxillofacial diseases, as well as services such as oral beauty. Its main task is to meet people's needs for oral health and improve the level of oral health. Oral medical institutions mainly include oral hospitals, oral clinics, oral outpatient departments, etc. The services provided by these institutions cover all aspects of oral diseases, such as the treatment of caries, periodontal diseases, pulp diseases, periapical diseases, tooth defects, malocclusion, etc., as well as oral beauty, oral restoration and other services.

[0003] In oral medical operations, due to the complexity inside the oral cavity, an oral mirror is needed to assist medical staff in performing examinations and auxiliary treatment operations during the preliminary examination and subsequent treatment operations. Specifically, an oral mirror is an optical endoscope that can directly show the patient the state inside the oral cavity through images, including the detailed conditions of teeth, gums, oral mucosa and other parts. Doctors can use the oral mirror to visually check whether there are lesions inside the patient's oral cavity, such as tooth decay, dental calculus, tooth irregularity, oral ulcers, impacted wisdom teeth, tooth defect, tooth body defect, and various oral mucosal diseases.

[0004] Currently, for the operation of an oral mirror, usually medical staff place the end of the oral mirror at the tiger's mouth and hold the handle in the middle of the oral mirror with the thumb and index finger. During use, the operator needs to rotate the thumb and index finger relative to each other to flip the oral mirror, and drive the oral mirror to adjust its position by rotating the wrist to adapt to the diseased area inside the patient's oral cavity. However, due to many factors such as the limitation of the flexibility of the oral mirror itself, the limitation of the oral cavity space of the patient, and the limitation of the wrist movement of the medical staff, there are still many operation blind spots during the operation of the oral mirror, and the flexibility is limited, which increases the operation difficulty of the medical staff and affects the diagnosis and treatment efficiency. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an oral mirror with multi-angle adjustment to fundamentally solve the problem that the flexibility of the existing oral mirror is limited, resulting in increased operation difficulty and affecting the diagnosis and treatment efficiency.

An air vent 342 for connecting the air duct 111 is provided between the lens sleeve 341 and the movable disk 33.

[0025] In specific implementation, medical staff can guide the oral endoscope assembly 3 into the patient's oral lesion through holding the operation assembly 1 for operation and inspection. During the process, medical staff can place the end of the oral endoscope at the tiger's mouth during the conventional grasping operation, and grasp the handle in the middle of the oral endoscope with the thumb and index finger, which can meet the inspection of lesions in relatively shallow parts of the oral cavity. When inspecting lesions in the deep part of the oral cavity or some relatively hidden lesion areas, medical staff can use the grasping method of the operation assembly 1 to operate and use the multi-angle adjustable oral endoscope of the present invention. Specifically, medical staff can first hold the handheld part 11 with their hand and place the index finger, middle finger, ring finger, little finger, etc. on the four elastic finger buckles 12 respectively. This grasping method improves the contact between the medical staff's palm and the operation assembly 1 to a certain extent, and at the same time ensures the stability during the grasping operation of the multi-angle adjustable oral endoscope, so as to avoid the risk of slippage of the oral endoscope during the operation due to less contact points between the palm and the oral endoscope in the conventional grasping operation. Then, medical staff can guide the oral endoscope assembly 3 and part of the extension part 2 into the patient's oral cavity for inspection operation, and adjust the linkage component according to the position of the oral lesion, that is, adjust the flipping angle of the oral endoscope component 34 through the elastic finger buckles 12 from top to bottom of the handheld part 11 in turn to adapt to the patient's oral lesion. Specifically, first, the operation principle of the elastic finger buckles 12 arranged from top to bottom on the handheld part 11 is described, and they respectively correspond to the first linkage component, the second linkage component and the third linkage component. When medical staff need to control the oral endoscope component 34 to move to the left along the X-axis, they can press the uppermost elastic finger buckle 12 towards the handheld part 11 by controlling the index finger, and drive the first linkage component to perform corresponding transmission. The elastic finger buckle 12 drives the one-way bolt 13 and the first driving screw 14 to move horizontally in turn, so that the first driving screw 14 presses the first elastic part 153 at one end of it to cause deformation. It can be understood that the first elastic part 153 is used to ensure that medical staff can generate relative resistance when pressing the elastic finger buckle 12, so that medical staff can stably control the movement stroke of pressing the elastic finger buckle 12, and at the same time provide a certain amount of movement space for the first driving screw 14 to move horizontally stably. At the same time, because there is a transmission relationship between the first driving screw 14 and the transmission link 16, in some optional embodiments, it can be screwed or gear-driven. And because the transmission link 16 itself is limited by the positioning buckle 112 during the transmission process, the driving force originally for the horizontal movement of the transmission link 16 is converted into an axial rotational force along the horizontal movement direction, such as Figure 3As shown, the drive link 16 is driven to perform a flipping operation around the thread track on the surface of the drive link 16, so that the drive link 16 connecting the movable disk 33 moves towards the direction of being embedded in the handheld part 11, so as to pull the movable disk 33 to flip towards the left based on the third elastic part 343 at the bottom. In addition, in some alternative embodiments, a spring can also be selected at one end of the drive link 16 close to the movable disk 33, so as to avoid the situation of relative pulling between the two drive links 16 during the subsequent process of controlling the oral endoscope assembly 34 to flip left and right along the X-axis. At the same time, a spring design can also be adopted for the movable part 32, which can be used to synthesize the pulling forces of the two drive links 16 and make an adaptive deformation adjustment.

[0026] Furthermore, through the above description of the first linkage assembly, the transmissions of the second linkage assembly and the third linkage assembly with the same structural design can be obtained, that is, the adjustment operation of the oral endoscope assembly 34 is realized by pressing the corresponding elastic finger buckle 12 with the middle finger and the ring finger respectively, so that the oral endoscope assembly 3 can sequentially realize the left and right sides along the X-axis and the one-way flip along the Y-axis, that is, the flip operation towards the mirror surface 345. In addition, while the above operations realize the left and right flips of the oral endoscope assembly 34 along the X-axis and the one-way flip along the Y-axis, it can also be that the medical staff simultaneously drives the second linkage assembly and the third linkage assembly, as well as the first linkage assembly and the third linkage assembly to perform regional adjustments between the right side of the X-axis and the Y-axis, and between the left side of the X-axis and the Y-axis. So that when the medical staff simultaneously presses the elastic finger buckles 12 on the first linkage assembly and the second linkage assembly, the movable disk 33 is simultaneously subjected to the pulling forces from the X-axis and the Y-axis. On this basis, by only increasing the pulling force on a certain axis, the movable disk 33 can be made to move towards the direction of this axis. It can be understood that the movable disk 33 can perform a "rocker-type" adjustment with the movable part 32 as the center. Among them, such as the direction control rocker in a common game controller, the gear shift rocker in a vehicle, etc., to further improve the flexibility of the oral endoscope assembly 3 and efficiently adapt to the oral lesion of the patient to achieve multi-angle adjustment.

[0027] Furthermore, during the diagnosis and treatment observation of a patient by the oral endoscope assembly 34, since the oral endoscope assembly 34 may enter the oral cavity relatively deeply, the affected area reflected by the mirror surface 345 may be small, making it impossible to observe carefully. Based on this situation, the medical staff can adjust the current mirror surface 345 through the fourth linkage assembly. Specifically, the operator presses the elastic finger buckle 12 corresponding to the little finger at the bottom, which causes it to push the linkage rod 110 to move in the pressing direction and pull the corrugated airbag 19 to open. During the opening process, negative pressure will be generated inside the corrugated airbag 19, and the air in the mirror sleeve 341 and the mirror surface 345 will be discharged through the air duct 111, causing negative pressure inside them as well. After negative pressure is generated on the mirror surface 345, it will deform inwards towards the mirror sleeve 341. The mirror surface 345 after the inward deformation has a magnifying effect, allowing the medical staff to perform a magnifying operation on the affected area to facilitate careful observation of the situation of the affected area and improve the quality of diagnosis and treatment. It should be noted that for the mirror surface 345 to achieve deformable operation, a PE mirror material or a mirror acrylic board can be selected for production and use.

[0028] In addition, in some alternative embodiments of the present invention, to ensure the shaping and stability of the oral endoscope assembly 34 after each adjustment, the reset assembly 17 and the locking assembly 18 can be operated, and the one-way bolts 13 on each elastic finger buckle 12 are cooperated to fix the adjustment path. Specifically, the medical staff can drive the second drive screw 173 to rotate axially by rotating the reset button 171. During this process, the second drive screw 173 can drive the transmission sleeve shaft 181 connected to its surface to perform transmission adjustment. It should be noted that the transmission sleeve shaft 181 is composed of two axially opposite threaded shafts, and a movable shaft is provided between the two threaded shafts so that the two threaded shafts can perform relative rotation, and the internal threads for connecting the second drive screw 173 between the two threaded shafts are arranged in opposite directions. In some alternative embodiments, it can also be that one threaded shaft is fixedly connected to the second drive screw 173, and the other threaded shaft is in a screwed connection with the second drive screw 173. Therefore, during the process of driving the transmission sleeve shaft 181 by the second drive screw 173, at least one threaded shaft on the transmission sleeve shaft 181 will rotate under the drive of the second drive screw 173, and drive the linkage arm 182 installed on the surface of the corresponding threaded shaft to flip towards or away from the other linkage arm 182, so as to realize the buckling and unfolding of the locking ring 183. Further explanation for this is that when the locking ring 183 is buckled, it can form a package for the one-way bolt 13, and a total of four locking rings 183 are provided corresponding to the four one-way bolts 13, and a locking buckle 184 extending from the inside of the locking ring 183 to achieve one-way fixation with the one-way bolt 13 is provided. It can be understood that under the restriction of the locking ring 183, the one-way bolt 13 can only realize the movement trajectory of the elastic finger buckle 12 extending towards the handheld part 11. The principle is similar to that of the existing plastic strip tie and can be understood by those skilled in the art. Thus, the adjustment path can be fixed after each pressing of the elastic finger buckle 12 to ensure the stability of the oral endoscope assembly 34 following the adjustment. In addition, when the medical staff does not need to use the locking assembly 18, only need to reverse-rotate the reset button 171 to make the locking assembly 18 in an unfolded state, and the adjusted oral endoscope assembly 34 with the implementation path fixed will also perform a self-resetting operation due to the influence of the third elastic part 343 after each adjustment.

[0029] In summary, for the multi-angle adjustable oral mirror in the above embodiments of the present invention, the four elastic finger buckles 12 can be respectively used to drive the first linkage component, the second linkage component, the third linkage component and the fourth linkage component, so as to drive the three transmission link rods 16 to drive the oral mirror assembly 3 to respectively flip unidirectionally along the left and right sides of the X-axis and along the Y-axis, greatly improving the flexibility of the multi-angle adjustable oral mirror of the present invention, facilitating the operation of medical staff and improving the diagnosis and treatment efficiency. At the same time, through the fourth linkage member, a vacuum environment can be created inside the oral mirror assembly 3, and the oral mirror assembly 3 can be controlled to deform from a plane mirror to a concave mirror to magnify the affected area for the convenience of medical staff to observe and improve the diagnosis and treatment quality, solving the problem that the current flexibility of the oral mirror is limited, resulting in increased operation difficulty and affecting the diagnosis and treatment efficiency.
