Abstract
The invention discloses an instrument for cutting bones, particularly a special swaying saw for cutting bone on the corner of the lower jaw, mainly used for undertaking bone-cutting on the corner of the lower jaw within the oral cavity.
Description
Technical field
The present invention relates to a kind of medical osteotomy instrument, particularly a kind of swinging saw special for mandibular angle bone cutting is mainly used in from the human oral cavity inboard to angle of mandible and carries out the osteotomy processing.
Background technology
Big or little direct decision face shape that whether angle of mandible of human body protrudes and protrude, often will carry out osteotomy to angle of mandible at present in the human face medical cosmetology handles, the employed instrument of existing osteotomy mainly is a swing saw, its structure is: a columned saw bar is arranged, its length is 60 millimeters-70 millimeters, end at the saw bar is fixed with flat saw blade, the plane at saw blade place is the right angle with the angle that saw bar centrage is become, the periphery of saw blade is provided with sawtooth, the other end at the saw bar is connected to link, to saw the link of bar and the union joint of handle one end during use joins, be provided with actuating device in the handle, the outfan of actuating device is joint in succession, the input of actuating device joins by flexible axle and driving device, driving flexible axle by driving device in the work process rotates, flexible axle drives the actuating device running again, the outfan of actuating device drives saw bar and saw blade swing by union joint, reach the purpose of osteotomy, the swing saw of existing this structure has following shortcoming: the shape because the angle of the plane at saw blade place and saw bar centrage meets at right angles, and the saw bar is cylindrical and shorter, it is very inconvenient to stretch in the oral cavity when angle of mandible carried out sawing, its right angle and human body angle of mandible are incompatible, block surgical field of view, in narrow and small operative space when amputation angle of mandible and ascending branch place, expose the deficiency of handling extreme difference, several exhaling can't be operated, and makes troubles to operation; In order to address the above problem, the reflex saw that utilizes that has undergos surgery, its structure is that the actuating device outfan of handle inside is reciprocating when work, can drive the cutter straight reciprocating motion, this mode can not undergo surgery from inside, oral cavity, need the skin auxiliary incision, the operation of exposing vestige is arranged, neither ideal modus operandi.
Summary of the invention
The purpose of this invention is to provide a kind ofly carry out from the oral cavity not blocking in mandibular angle bone cutting operation and the operation, the easy to operate special-purpose swing of mandibular angle bone cutting certificate, overcome the deficiencies in the prior art.
Swinging saw special for mandibular angle bone cutting of the present invention, the saw blade that comprises saw bar and the tabular band saw tooth of fixedlying connected with saw bar one end, the other end of saw bar is provided with link, and the number of degrees of the plane at saw blade place and the angle α that centrage became that saws bar are between 95 °-115 °.
Swinging saw special for mandibular angle bone cutting of the present invention, the number of degrees of wherein said angle α are 95 ° or 100 ° or 105 ° or 110 ° or 115 °.
Swinging saw special for mandibular angle bone cutting of the present invention, the length of wherein said saw bar are 95 millimeters--105 millimeters, and tapered near saw blade one end.
Swinging saw special for mandibular angle bone cutting of the present invention, the height dimension of wherein said sawtooth are 1.8 millimeters-2.2 millimeters.
Swinging saw special for mandibular angle bone cutting of the present invention, because it comprises the saw blade of saw bar and the tabular band saw tooth of fixedlying connected with saw bar one end, the other end of saw bar is provided with link, the number of degrees of the angle α that centrage became of the plane at saw blade place and saw bar are between 95 °-115 °, greater than the right angle, and the front portion of saw bar is promptly tapered near the saw blade part, diminish gradually to its cross section of saw blade direction, its length is longer than saw bar of the prior art, therefore very convenient when carrying out mandibular angle bone cutting from the oral cavity, do not block the visual field, operation easily, good operation effect, speed is fast, the swing saw of different angles can be fit to each regional angle of mandibular bone, thickness, it is more accurate to operate, quick; Not only do not block the visual field behind the saw bar lengthening, also have the effect that guiding is provided for osteotomy.
Description of drawings
Fig. 1 is the structural representation of swinging saw special for mandibular angle bone cutting of the present invention;
Fig. 2 is that sketch map is looked on the right side shown in Figure 1;
Fig. 3 is the user mode sketch map of swing saw.
The specific embodiment
As shown in the figure: 1 is the saw bar, the right-hand member of saw bar 1 is a link 4, the section of link 4 is triangular shape, the left end of saw bar 1 is equipped with saw blade 2, saw blade 2 is tabular, and edge, its underpart is circular arc and is processed with sawtooth 3 that the height of sawtooth 3 is determined between 1.8 millimeters-2.2 millimeters, the top of saw blade 2 is inserted in the contiguous block 13, between saw blade 2 and the contiguous block 13, all adopt welding manner to fixedly connected between the termination of contiguous block 13 and saw bar 1.The plane at saw blade 2 places is determined between 95 °-115 ° with respect to the number of degrees of the angle α that centrage became of saw bar 1, in order to be fit to each zone of angle of mandible, the number of degrees of angle α can be defined as 95 °, 100 °, 105 °, 110 °, 115 ° respectively, form the swing saw of various different angles.The forward part of saw bar 1 is taper near saw blade 2 parts promptly, circular cone or pyramid all can, diminish gradually to its cross section of saw blade 2 directions, this partial-length accounts for half of saw bar 1 length or gets final product mostly.The length of saw bar 1 is at 95 millimeters--and determine between 105 millimeters, promptly be defined as 95 millimeters or 100 millimeters or 105 millimeters and all can.Link 4 is the prior art part with the connected mode of union joint 12 and actuating device, flexible axle 7, driving device 11, the foot switch plate 9 in the handle 6, no longer describes in detail.
As shown in Figure 3: during use, select to be fit to the swing saw of angle according to each zone of human body angle of mandible, the link 4 and union joint 12 plug-in mountings of handle 6 one ends are fixed, hand-held handle 6, fork 10 connects power supply, make driving device 11 work by pedal switch 9, driving flexible axle 7 rotates, flexible axle 7 drives the actuating device running in the handle 6, the outfan of actuating device drives union joint 12, saw bar 1, saw blade 2 swings successively, utilize saw bar 1 that saw blade 2 is sent in the oral cavity, angle of mandible is carried out osteotomy handle, very convenient accurate.
