Extension bar, the other end of splined shaft is set to male end, and the male end exposes link, external screw thread peripheral hardware fixing nut, institute
Connecting rod is stated provided with handle, the side of the saw frame is provided with fixed mount, institute's saw blade body include Straight blade, semicircle saw blade,
Standing screw, the Straight blade two ends are respectively equipped with semicircle saw blade, and one end of the semicircle saw blade is connected with Straight blade, and half
The other end of circular saw blade is provided with support bar, and the support bar is provided with standing screw, and the standing screw passes through adjusting nut
It is detachably connected with fixed mount, the outside of semicircle saw blade is provided with sawtooth, and the sawtooth of semicircle saw blade is directed away from Straight blade
Direction.
Further, the handle is provided with elastic bumps, is easy to doctor to grasp.
Further, the splined shaft is mutually perpendicular to connecting rod.
Further, the Straight blade and semicircle saw blade are tangent.
Further, the saw blade body is provided with cooling tube, and the cooling tube is provided with multiple nozzles.
Further, the saw frame is set to cavity structure, and saw frame cavity structure is connected by micro pump with cooling tube, saw frame
Interior to be provided with cooling water, the micro pump is connected by switch with battery.
Further, multiple spline tooths being parallel to each other are uniformly provided with the splined shaft, the spline tooth is parallel in axle
Heart line.
The utility model has the advantages that：The setting of handle facilitate doctor adjust hand angle, it is to avoid handle and
Arm blocks surgical field of view, is easy to observe bone situation；The structure of saw blade body is novel, can avoid link etc. to lesion bone
Tissue around head causes further injury, in specific implementation process, can also be using semicircle saw blade to narrow
Position is cut, and is conducive to the implementation of bone surgery；Saw blade can be cooled down.
