Abstract
The utility model relates to electric running saw for dentofacial surgery, which possesses enough strength. The saw blade is in fair length and sustainable of break. The incision line is comparatively straight and can guarantee the incision of bones with equal distance. The electric running saw comprises a saw blade holding device, which is a cylinder mouthpiece with anti-skid device. The saw blade holding device is fixedly connected to the saw rod. A double-edged saw blade is provided in the saw rod. The saw rod is a cylinder equipped with anti-skid device. The double-edged blades are in equal distance and the anti-skid device of the saw rod is an anti-skid hook arranged at the tail.
Description
One, technical field:
This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of electric reciprocating saw in use for jaw surgery, and it is used for decorative sursery and equidistantly cuts the jawbone operation.
Two, background technology:
The people of current exquisite shape of face U.S. is the women particularly, more and more, the hope oneself that is not oval face has an oval face, must carry out maxillofacial bone part resection operation, particularly chin and needs symmetric a part of jawbone that cut out to the face that protracts oversize but will make oneself face become oval face.Present way is to cut out unnecessary jawbone with reciprocating sow, and the saw blade of this saw is very thin, and it is thick to be generally 0.35mm, and every limit will be sawed twice and could unnecessary jawbone be cut out.Because saw blade is very thin, the line of sawing out is difficult to guarantee straight, guarantee that the jawbone that both sides cut out is just the same just more difficult, just may cause because of both sides cut out not equidistant jawbone that face is askew after the knitting, and this just influences surgical effect greatly.Therefore the efficient of this single saw blade osteotomy is low, and weak effect prolongs operating time, strengthens patient's misery.On the other hand, to mobile phone itself, because the saw blade clamping device is that the thick saw blade of special clamping 0.35mm is used, because saw blade is very thin, so saw blade can not do oversizely, otherwise saw blade is easy to bending even fractures, and therefore giving needs saw to come difficulty than the deep bit strip.
Three, utility model content:
This utility model provides a kind of electric reciprocating saw in use for jaw surgery in order to solve the weak point in the above-mentioned background technology, and it has enough intensity, and saw blade does not need very long, and saw blade is not easily broken, and line of cut is also relatively more straight, and can guarantee to cut equidistant bone.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of electric reciprocating saw in use for jaw surgery, its special character is: comprise the saw blade clamping device, the saw blade clamping device is cylindric interface and anti-skidding mechanism is housed that the saw blade clamping device is fixedlyed connected with the saw bar, be fixed with the twolip saw blade on the saw bar, the saw bar is cylindrical bar and is provided with anti-skidding mechanism.
Above-mentioned twolip saw blade is equidistant twolip saw blade.
The anti-skidding mechanism of above-mentioned saw handle is its aft mounted anti-skidding colluding.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
This utility model changes original single saw blade into two saw blades, and original thin slice saw blade the fixedly saw blade method on the mobile phone of directly being clipped in is changed into the clamping means of cylinder shape belt anti-skid structure, directly the shortcoming of clamping thin slice saw blade is that saw blade is very near from mobile phone, and the diameter of mobile phone is bigger, reaching the oral cavity just only takes saw blade is done length than the deep, but saw blade oversize will coping saw blade too thin (generally have only 0.35mm thick) and crooked, the line that saw is come out is not straight, and saw blade is also disconnected easily, after using cylindrical bar instead, the length of bar can be made different length as required, because diameter reaches ￠ 2.35, so enough intensity is arranged, and two saw blades just are welded in the front end of bar, saw blade does not need very long, so saw blade is not easily broken, and line of cut is also relatively more straight.And, can guarantee to cut equidistant bone owing to be equidistant two saw blade.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of two saw blade cutters.
Among the figure, 1-micro medical brushless electric machine surgical drill, the 2-changement, the 3-drive mechanism, the 4-clamping device, the two saw blade cutters of 5-, 6-saws bar, the two saw blades of 7-.
Five, the specific embodiment:
Referring to Fig. 1, but the micro medical brushless electric machine that comprises autoclave sterilization as power source, it drives a steering mechanism 2, changes original rotatablely moving into reciprocating motion, steering mechanism 2 drives drive mechanism 3 and cutter clamping devices 4.Cutter clamping device 4 is for cylindric interface and anti-skidding mechanism is housed, and when motor rotated, cutter clamping device 4 drove cutter and moves reciprocatingly, and reaches the effect of reciprocating sow.Referring to Fig. 2, the handle of cutter is the cylindrical saw bar 6 of rustless steel, is processed into anti-skidding colluding at its afterbody, behind the socket of the cutter clamping device 4 of sawing bar 6 insertion mobile phones, revolves to turn 90 degrees saw handle 6 is caught on, and use fixed by nut, prevents from reciprocating motion saw handle 6 to be pulled out.Two saw blades 7 are welded on the handle of a knife by different specification requirements at the front end of saw bar 6 and form one complete equidistant twolip sawed.Saw blade is to be made by special material, and characteristics are: though its bending, it can not break yet, and prevents from that coping saw blade from fractureing to cause unexpected injury.In addition, be coated with one deck special material with vacuum method on saw blade, made its case hardness surpass HRC-70, promptly also hard than tool steel, it is sharp that blade teeth is remained, and prolongs the service life of saw blade.
