Abstract
A multifunctional craniotomy saw blade relates to an improvement of a craniotomy saw blade structure, particularly, the utility model discloses the multifunctional craniotomy saw blade. The utility model provides the multifunctional craniotomy saw blade capable of avoiding the damage to a duramater when a skull is sawed and having a limiting function. The multifunctional craniotomy saw blade comprises a saw blade body with a blade at the outer edge and an axial hole is formed in the saw blade body. The multifunctional craniotomy saw blade is characterized in that an arc limiting block is arranged at the surface of the saw blade body corresponding to the blade.
Description
Technical field
This utility model relates to a kind of improvement of craniotomy saw chip architecture, and specifically, this utility model relates to a kind of Multifunction open cranium saw blade.
Background technology
Traditional craniotomy saw sheet function singleness, does not possess limit function, opening in cranium process, and easy damaged cerebral dura mater; For checking that brain injury and pathological changes cause harmful effect.
Summary of the invention
This utility model is exactly for the problems referred to above, while providing one to avoid sawing skull, damages cerebral dura mater, has the Multifunction open cranium saw blade of limit function.
For realizing above-mentioned purpose of the present utility model, this utility model adopts following technical scheme, and this utility model comprises that outer rim is the blade bodies of blade, is provided with axis hole in blade bodies, it is characterized in that: blade bodies surface is provided with arc-shaped limit piece corresponding to blade.
As a kind of preferred version of the present utility model, described blade bodies one side is set to fan-shaped.
As another kind of preferred version of the present utility model, described blade bodies is set to circle, described axis hole eccentric setting.
Further preferred version, the outer rim eccentric setting of described arc-shaped limit piece and blade bodies.
The beneficial effects of the utility model: 1, this utility model, by arc-shaped limit piece is set, can guarantee the depth of cut of blade bodies, guarantee not destroy cerebral dura mater, for checking that brain injury and pathological changes are without impact.
2, this utility model is set to fan-shapedly by blade bodies one side, is convenient to privileged sites to cut.
3, this utility model is set to circle by blade bodies, and by axis hole eccentric setting, can cut skull by a side of blade bodies, uses the opposite side cutting spinal cord of blade bodies.
4, because the thickness of skull diverse location is also different, therefore, the outer rim of this utility model arc-shaped limit piece and blade bodies is set to eccentric structure, is convenient to the cutting to skull diverse location.
