According to some embodiments of the present invention, the first connection portion 210 and the second connection portion 320 are rotationally connected.
Specifically, the first connection portion 210 of the first handle 200 and the second connection portion 320 of the second handle 300 are alternately and rotationally connected through a rivet, at this time, the mouse molar tooth extractor 100 is in a tiger-jaw shape, and an operator controls the clamping action and the clamping force of the first clamping portion 220 and the second clamping portion 310 on the molar tooth by manipulating the rear end of the first handle 200 and the rear end of the second handle 300.
Referring to fig. 1, according to some embodiments of the present invention, the first connection portion 210 is fixedly connected to the second connection portion 320, and the first handle 200 and the second handle 300 are made of an elastic material.
Specifically, the first connecting portion 210 and the second connecting portion 320 may be fixedly connected by welding, fusing, or by means of a preload member such as a bolt and a nut. When first handle 200 and second handle 300 are not atress, first clamping part 220 and second clamping part 310 keep certain interval, mouse molar extractor 100 is the tweezers form this moment, and operating personnel is when carrying out the operation of extracting teeth, through pinching first handle 200 and second handle 300, can order to order first clamping part 220 and second clamping part 310 to be close to each other, extracts the operation to the molar, and because the elasticity of first handle 200 and second handle 300, after loosening first handle 200 and second handle 300, first clamping part 220 and second clamping part 310 resume original interval, do not need manual reset.
Because mouse molar 400's fragility is great, directly crumble easily when receiving great clamping-force, and human holding power through the finger often is less than the holding power, when mouse molar tooth extractor 100 design was tweezers form, operating personnel was through holding power to mouse molar 400 carry out the centre gripping, has reduced the clamping-force upper limit that mouse molar 400 can receive in other words, and operating personnel also can more subtle control clamping-force through holding, has reduced the possibility that mouse molar 400 crumbles because of the clamping-force.
According to a further embodiment of the present invention, the minimum distance between the first clamping portion 220 and the second clamping portion 310 is 1.5-2.5mm.
Specifically, the width of the mouse molar 400 is usually about 1mm, the distance between the first clamping portion 220 and the second clamping portion 310 is set to be 1.5-2.5mm, for example, 1.5mm, 2mm or 2.5mm, and the distance between 1.5-2.5mm is slightly greater than 1mm of the width of the mouse molar 400, so that the first boss 221, the second boss 311 and the third boss 313 are advantageously disposed on opposite sides of the mouse molar 400, and when the first boss 221, the second boss 311 and the third boss 313 are respectively inserted into the first gap, the second gap and the third gap, the probability of interference between the first clamping portion 220 and the second clamping portion 310 and the mouse molar 400 is lower. When the distance between the first clamping portion 220 and the second clamping portion 310 is greater than 2.5mm, the operator needs to use a larger holding force to overcome the elasticity of the first handle 200 and the second handle 300 to make the first clamping portion 220 and the second clamping portion 310 approach each other, and after the distance between the first clamping portion 220 and the second clamping portion 310 is increased, the first clamping portion 220 and the second clamping portion 310 are more likely to interfere with the oral cavity of the mouse, which affects the operation of the operator and is likely to damage the oral tissue of the mouse.
Referring to fig. 1, according to some embodiments of the present invention, a first handle 200 is provided with a first non-slip pattern 230 and a second handle 300 is provided with a second non-slip pattern. Through being provided with anti-skidding line, frictional force when increasing operating personnel and using mouse molar tooth extractor 100 reduces the probability that mouse molar tooth extractor 100 skids when using, is favorable to operating personnel to hold between the fingers or hold mouse molar tooth extractor 100 more.
It should be noted that the second anti-slip pattern is not shown in the drawings.
According to some embodiments of the present invention, the maximum width of the first handle 200 and the second handle 300 is 1cm. Since the mouse molar 400 has a small volume, a large visual space needs to be reserved to ensure the operation accuracy of the operator, which needs to reduce the volume of the mouse molar extractor 100 as much as possible, but needs to reserve a certain width for the first handle 200 and the second handle 300 to be held or held by the operator. When the width of the portion for pinching or holding the first handle 200 and the first handle 200 is 1cm, the sight shielding of the mouse molar tooth extractor 100 can be reduced as much as possible while the operation requirement of an operator on the mouse molar tooth extractor 100 is met, and the operator can conveniently extract the mouse molar tooth 400.
Referring to fig. 1, according to some embodiments of the present invention, a thickness of the first handle 200 from the first clamping portion 220 to the first connecting portion 210 is greater than a thickness of the second handle 300 from the second clamping portion 310 to the second connecting portion 320.
Specifically, the first cheek root 410 and the second cheek root 420 correspond to tooth roots of the mouse in the oral cavity close to the cheek direction, when the first boss 221 is inserted into the first gap, one end of the first clamping portion 220 far away from the first boss 221 needs to be abutted against the oral cavity wall of the mouse to open a sufficient space to insert the first boss 221 into the first gap, and an operator also needs a certain sight line space to position the first gap. By increasing the thickness of the first handle 200 from the first clamping portion 220 to the first connecting portion 210, the contact area between the first handle 200 and the inner wall of the oral cavity is increased to expand a larger space, and the increased thickness of the first handle 200 is equivalent to the increased structural strength of the first handle 200, so as to reduce the probability of irreversible bending or breaking damage of the first handle 200 when abutting against the inner wall of the oral cavity.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
