[0002] Oral cavity examining mirror is a kind of medical instrument for oral cavity examination and treatment, and its main function is to help doctors clearly observe the situation inside oral cavity, including teeth, gums, tongue, cheek and throat, so as to carry out accurate diagnosis and treatment.Oral cavity examining mirror is usually composed of two parts of observation lens and handle.The lens is used to reflect and transmit light, so that doctors can observe the situation inside oral cavity;the handle part is convenient for doctors to hold and operate.The handle part is usually in the form of straight rod, and since the handle part is in the form of long straight rod, the moving range of observation lens in oral cavity is limited during oral cavity examination, and since the observation lens needs to be used for reflection and observation, the handle needs to be rotated and moved to find a suitable observation angle, but the activity range in oral cavity is limited, so that the medical operator can only support the handle part outside, and it is difficult to quickly adjust the angle of lens, so as to bring inconvenience to the medical operator during examination, and it is difficult to finely adjust the lens, which affects flexible movement and use of gestures, and also affects the efficiency of treatment. SUMMARY

[0003] The utility model aims at providing a kind of hand control bending deflection type oral cavity examining mirror, solve the problem that the straight rod handle oral cavity examining mirror of traditional in medical operator examination is difficult to quickly adjust to suitable observation angle, it can be flexibly and quickly adjusted the angle of observation lens, it is convenient to flexibly operate.

[0004] The technical scheme adopted by the utility model is as follows: the hand control bending deflection type oral cavity examining mirror includes handle and observation mirror, and the technical key points are as follows: the central axis of the front section of the handle is provided with a muscle plate that can be elastically bent to both sides, two rows of oblique tooth-shaped protrusions are symmetrically arranged on both sides of the muscle plate, the outer end of the protrusion is narrow, and the root is wide;symmetrical sliding grooves are arranged on both sides of the middle section of the handle, sliding blocks are arranged in the sliding grooves on both sides respectively, the sliding blocks are connected with traction ropes, the traction ropes pass through the two rows of oblique tooth-shaped protrusions in sequence and are connected with the observation mirror;the protrusions are provided with push buttons on the outer side of the handle.

[0005] A reset spring is arranged in the sliding groove.

[0006] The number of protrusions in each row is 5 to 10.

[0007] The front section of the handle with protrusions is provided with a medical plastic film.

[0008] The utility model discloses a have's advantage and beneficial effect is: the utility model discloses a hand -controlled bending deflection formula oral cavity inspection mirror utilizes the elastic bending of the muscle plate of the middle axle setting of handle front section to two sides, and the muscle plate both sides symmetry sets up two rows of oblique tooth shape's protruding piece, can make handle front section to two sides elastic bending, adopt the symmetric slide groove setting slider on handle middle section both sides, connect the towrope, in proper order pass two rows of oblique tooth shape's protruding piece connection observation mirror, and the protruding piece sets up the push button on handle outside, can through the manual control of medical treatment operator and push slider forward or backward, and then drive the towrope and make handle front section to two sides bend, make observation mirror deflect to two sides, adjust observation angle.

[0016] According to Figures 1-5 The utility model will be described in detail. The embodiment is such as Figures 1 to 3As shown, a manually controllable bending and deflecting oral endoscope includes a handle and an observation mirror 1. The central axis of the front section of the handle is equipped with a flexible rib 2 that can be elastically bent to both sides. The rib is made of elastic plastic or steel, thin in the transverse direction and large in the longitudinal direction, allowing it to bend elastically to both sides while remaining fixed in the longitudinal direction. Symmetrically arranged on both sides of the rib 2 are two rows of oblique tooth-shaped protrusions 3. The protrusions are narrow at the outer end and wide at the root, forming trapezoidal blocks. An oblique angle is formed between adjacent protrusions 3 in the longitudinal direction, creating a triangular gap that allows the elastic rib to bend the protrusions. Symmetrical sliding grooves 6 are arranged on both sides of the middle section 5 of the handle. Slider 9 is installed in each of the two sliding grooves, and the sliders are connected to traction cables 4. The traction cables pass through the two rows of oblique tooth-shaped protrusions 3 and connect to the observation mirror 1. The protrusions have through holes through which the traction cables 4 can pass. The front ends of the traction cables are connected to the two sides of the root of the observation mirror. Push buttons 7 are located on the outside of the handle, which move the sliding grooves.

[0017] As a further improvement, such as Figure 1 and Figure 2 As shown, a return spring 8 can be installed inside the slide groove 6. When the push button is not pushed by an external force, the return spring 8 can pull the slide groove to stay in the middle of the slide groove, preventing the front part of the handle from wobbling and maintaining stability. Five to ten protrusions 3 can be used in each row to ensure a smooth and gradual bending process for the front part of the handle. Figure 5 As shown, a medical plastic film 10 can also be provided at the front of the handle with protrusions to prevent the protrusions, ribs and traction rope at the front of the handle from direct contact with the patient's mouth, making it easy to clean and disinfect.

[0018] like Figure 4 As shown, during use, medical personnel can control the slider forward or backward with their fingers to push it while examining the patient's oral cavity and teeth. This causes the traction cable to pull the front part of the handle to bend to both sides, tilting the observation mirror to adjust the viewing angle. Therefore, it allows medical personnel to adjust the tilt angle of the observation mirror by pushing the push button with their fingers while holding the main handle stationary, making fine adjustments to observe the subtle conditions of the teeth. This facilitates examination, allows for flexible movement and gestures, and greatly improves treatment efficiency.

[0019] In summary, the purpose of this utility model has been achieved.
