Embodiment
[0034] 1. After the mouse is anesthetized, open the handle so that the front end holding the incisor is located at the incisor of the mouse.
[0035] 2. Fix one part of the two fixed support frames at the front end of the mouth gag near the root of the mouse's upper and lower incisors, and tighten the corresponding fastening knob 42 to securely fix the upper and lower incisors.
[0036] 3. After fixing the upper and lower incisors, adjust the mouth opening of the mouse according to the specific needs of the operation. The handle can be adjusted in three gears, allowing subsequent surgical instruments to enter the first and second jaws of the upper and lower jaws of the mouse mouth respectively. , Third molars, and then lock the handle, so that the gag is in place and fixed as a whole, and the mouse intraoral operation is performed.
[0037] 4. Unscrew the corresponding fastening knob 42 at the front end after the operation to separate the fixed support frame 1 from the upper a...

The invention discloses a novel mouth gag applied to a mouse. The novel mouth gag comprises fixed supporting shelves, a gear adjusting mechanism and forceps, the forceps are of a forcipated structurecomposed of two arch-shaped supports, the two arch-shaped supports are the first arch-shaped support and the second arch-shaped support respectively, and the middles of the first arch-shaped support and the second arch-shaped support are crossed through a locating part; the fixed supporting shelves are arranged at the two ends of the outer side of the head of the forceps, the gear adjusting mechanism is arranged in the middle of a holding handle of the forceps, and the inner sides of the first arch-shaped support and the second arch-shaped support are connected through the gear adjusting mechanism. The novel mouth gag is simple in structure, low in weight, small in size and low in cost and has a great application prospect; the requirements of various operations on the oral cavity of the mouse for different mouth opening degrees can be met; the oral cavity of the mouse can be fully exposed, the to-be-operated part is clear, the operation is convenient, the operation time is shortened, the efficiency is improved, and the operability and stability are very high.
Description
technical field [0001] The invention relates to the field of dental instruments, in particular to a novel mouth gag applied to mice. Background technique [0002] The gag is an essential key medical device in the field of stomatology. In the doctor's clinical operation, operations such as bonding fixed appliances and implant placement require high precision, and it is necessary to fully expose the patient's field of view in the oral cavity. At the same time, in order to alleviate the discomfort of long-term opening, the mouth gag came into being. At present, the commonly used mouth gag is "C" type gag, the lower part of the gag is "C" shape, and two small "C" type components are respectively fixed on the left and right ends to support the opening corner area. The "C" type gag has Elasticity, the mouth gag can be adjusted to a suitable size by applying tension or pressure to the small "C"-shaped components at the left and right ends, then placed in the patient's mouth, and f...
