Description

The surgical saw that is used for cutting off jawbone

Technical field

The present invention relates to a kind of surgical saw that is used for cutting off jawbone, certain specific part with the outstanding mandible both sides of cutting in for the plastic operation of outstanding mandible shaping, and relate to a kind of surgical saw that is used for cutting off jawbone especially, wherein serrated portion and handle are parallel to each other and move back and forth, thereby are used for cutting off jawbone.

Background technology

Usually, people's lower jaw refers to a part of stretching out from the face bottom.If a people has a specific width and a suitable ledge between the part about lower jaw, this people seems just smoother so.If the part that the people has too outstanding lower jaw or too caves in, it is just incurring dislike that this people seems.Specifically, when a people has bigger width and when each downside of lower jaw has the corner part of inclination between the part about lower jaw, it is just bigger that this face seems, so this people seems just fiendish and strong.So this people has just caused bad impression to others.

Therefore, recently, a kind of orthogonal lower jaw plastic operation is carried out widely, in this operation, seems very thin and slick appearance by the contour line of face being formed to the lower jaw both sides excision of giving prominence to the face below, thereby produces smooth impression.In above-mentioned rectangle lower jaw plastic operation, the mandible cutting operation is carried out widely, and in this operation, two jiaos of sides of mandible are cut off.In above-mentioned mandible cutting operation, make people's face seem outstanding or rectangular mandible ledge is cut off, thereby eliminate basically outstanding, might realize tangible surgical effect.

As shown in Figure 1, the existing mandible cast-cutting saw 1 that is used to form the rectangle lower jaw comprises the swingle 10 that forms thin straight bar-shaped profile, and the ellipse or the circular saw toothed portion 11 that are meshed with the front end of swingle 10.

As shown in Figures 2 and 3, in existing mandible cast-cutting saw, the rear end of swingle 10 engages with the clamp 21 of handle 2.Serrated portion 11 is driven by the rotary electric machine mechanisms that are arranged in the handle 2, with swingle slant operation in certain angular range integratedly, thereby with the angle part of the mandible 101 of the cutting of the angle shown in Fig. 4 and Fig. 5 skull 100.

Under the situation of existing mandible cutting operation saw, because the radius of turn of serrated portion 11 is bigger, thereby the crust of lower jaw is cut open, and mandible 102 is excised from the crust that is cut then.Therefore, after operation, formed an operative scar.In addition, as shown in Figure 5, because mandible is cut by the direction that approaches vertical face along, being seen in the horizontal lower jaw contour line is a smoothed curve.Yet lower jaw contour line of paramount importance for a people's impression, in the face front does not change shape.In addition, because mandible is cut under the sightless state in front in a kind of patient's face mask, even thereby have a contour line shape that the empirical expert doctor of prolonged operations also can not accurately change lower jaw.And when mandible was cut along an approaching specific direction perpendicular to the face front, institute's cutting part had the special angle corresponding to the face front.In this case, mandible is repeatedly cut a small depth, to overcome above-mentioned angle problem.Therefore, this operation is very difficult.As a result, using existing mandible cutting operation saw to change in the horizontal under the situation of mandible shape, can not change the shape of lower jaw contour line smoothly.Because mandible is cut along the vertical direction with respect to face, thereby embedded muscular tissue and neuromechanism may be damaged in operation in the mandible.

Summary of the invention

Therefore, one object of the present invention is to provide a kind of surgical saw that is used for cutting off jawbone, and this saw has overcome the problem that is run in the prior art.

Another object of the present invention is to provide a kind of surgical saw that is used for cutting off jawbone, this saw can be with a special angle cutting off jawbone corresponding to the face front, do not cut outside skin simultaneously by cutting mouth intracavity side and revise the face mask line, so that face can not stay any operative scar, and obtain the contour line of nature with simple operation technique.

For achieving the above object, a kind of surgical saw that is used for cutting off jawbone is provided, this saw comprises bar, this bar comprises the straight line portion that has by the fixed rear end of clamp of handle, and along between the left and right directions and a sweep that specific direction stretches out from the straight line portion front end with a specific deflection angle of downward direction, this saw also comprises serrated portion, and wherein sawtooth edge direction vertically downward is parallel to the straight line portion setting, and engages with the sweep front end of bar.
