Arc-shaped structure；Sheath handle, the sheath handle are connect with the tail portion integral type of the sheath tube body, in the sheath handle
Portion offers handle through-hole, and the handle through-hole is connected with the tubular structure.
Above-mentioned bone drill or trepan protection sheath, wherein the arc-shaped structure is close to the middle part one of the sheath tube body
The slope of side is greater than the arc-shaped structure close to the slope of the end side of the sheath tube body.
Above-mentioned bone drill or trepan protection sheath, wherein the length on the head of the sheath tube body is 25mm
Above-mentioned bone drill or trepan protection sheath, wherein the section of the sheath tube body is in circular.
Above-mentioned bone drill or trepan protection sheath, wherein the sheath handle is the plate structure of diamond shape, the sheath
The corner rounding of handle.
Above-mentioned bone drill or trepan protection sheath, wherein the outer diameter of the width direction of the sheath handle is greater than described
The outer diameter of sheath tube body.
Due to using above-mentioned technology, the good effect for being allowed to have compared with prior art is the utility model:
(1) the utility model can utilize arc-shaped structure opening, with sheath to the gradually propulsion of intervertebral foramen and by
Intervertebral foramen is gradually filled up, is finally stuck on Minor articulus, to reach the molding quantitative directional trend of intervertebral foramen.
Detailed description of the invention
Fig. 1 is the schematic diagram of existing bone drill or trepan protection sheath.
