The pry head plate includes blade, and the rear end of the pry head plate is arranged at main piece of front end, and the pry head plate is in upward
The arc of protrusion；The both sides of the pry head plate are set blade respectively；There is an angle ∠ a between the pry head plate and main piece,
The ∠ a are obtuse angle, -145 ° of the ∠ a=125 °；
The front end of the pry head plate is in half elliptic, and the front end of the pry head plate is equidistantly provided with three hooks, and
Longest distance is 10mm-22mm to three hooks between any two；Three hooks have angle ∠ a c, the ∠ c=between any two
20°-30°；There is angle ∠ a b, -175 ° of the ∠ b=165 ° between hook and the pry head plate.
It is preferred that, the length of the blade is 4/5ths of pry head plate length.
It is preferred that, the finger-hole is oval, 2/3rds of block rear portion width based on the major radius of the finger-hole.
It is preferred that, the radian of the pry head plate is 10 ° -15 °.
It is preferred that, the length of the pry head plate is 1/3rd of main block length.
It is preferred that, the hook is arc protruding upward, and the width of the hook front end is the width three of hook rear end
1/1 mono- to two.
It is preferred that, the length of the hook is 1st/1st to two/3rd of pry head plate length, the hook it is most long
Width for pry head plate length a quarter to 1/3rd.
It is preferred that, the radian of the hook is 55 ° -65 °.
By adopting the above-described technical solution, the beneficial effects of the utility model are：More than provided by the utility model
Structure, it is out of shape more to meet acetabular bone leading edge, more abundant for acetabular bone leading edge exposure in art, more can provide facility to perform the operation, more accord with
The need for closing operation now, and it is easy to use, therefore be adapted to promote.
Brief description of the drawings
The utility model is described further with reference to the accompanying drawings and examples.
(same section label is consistent in following figure)
Fig. 1 is overall structure diagram of the present utility model.
In figure, 1. main pieces, 1-1. finger-holes, 1-2. arcwall faces, 2. pry head plates, 2-1. blades, 3. hooks.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
