Embodiment Construction
[0022] In order to better understand the purpose, structure and function of the present invention, a rat periodontitis model modeling scissors of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0023] Such as figure 1 As shown, the first embodiment of the present invention includes a first scissor arm 1 and a second scissor arm 2. As can be seen from the figure, a first finger ring 11 and a second scissor ring 11 are respectively arranged outside the rear ends of the first scissor arm and the second scissor arm. Two finger rings 21, fingers can pass through the rings. The first scissors arm and the second scissors arm intersect in an "X" shape, and are connected by a pin shaft 3 (such as a rivet or screw) at the intersection, and the first scissors arm and the second scissors arm can both rotate around the pin shaft 3, thereby Implement opening and closing. It is conceivable that when the first finger ring and ...

The invention discloses a rat periodontitis model modeling scissors, which comprise a first scissor arm and a second scissor arm, a first finger ring and a second finger ring are arranged on the outer side of the rear end of the first scissor arm and the outer side of the rear end of the second scissor arm, the first scissor arm and the second scissor arm intersect, then are connected through a pin shaft and can rotate around the pin shaft, wherein a sliding wire puller is arranged on the first scissor arm, the sliding wire puller can slide along the first shear arm, a first steering structure is arranged at the front end of the first shear arm, a second steering structure is arranged at the front end of the second shear arm, a third steering structure is arranged on the sliding wire puller, ligature wires are wound on the first steering structure, the second steering structure and the third steering structure, and the ligature wires can change directions after passing through the steering structures. According to the device, an orthodontic ligature wire can be tightened in a narrow space of the oral cavity of a rat, the ligature wire cannot be loosened in the process of pressing the ligature wire into tooth gaps, the success rate of rat periodontitis model modeling is greatly increased, meanwhile, single-hand operation is achieved, and the operation difficulty is greatly reduced.
Description
technical field [0001] The invention belongs to the field of periodontitis animal model experimental equipment, and in particular relates to a rat periodontitis model modeling scissors. Background technique [0002] Periodontal disease is a common oral disease, one of the main causes of adult tooth loss, and a major oral disease that endangers human teeth and general health. The early symptoms of periodontal disease are not easy to pay attention to, resulting in long-term chronic infection of periodontal tissue, and recurrent inflammation, which not only damages the function of the oral masticatory system, but also seriously affects the health of the whole body. The prevalence of periodontitis is relatively high, and almost all teeth in the oral cavity of patients with periodontal disease have periodontitis in varying degrees. The establishment of experimental periodontitis animal model is expected to gradually develop into periodontitis on the basis of gingivitis, which pr...
