The through hole 8 of pilot pin 4；When taking bone, protection guiding bar 5, which is installed in, takes bone cylinder 11, and pilot pin 4 is interspersed in through hole 8, assembles completely
Bone object is taken to be moved along pilot pin 4.
Further, protection first 51 includes conical section and the cylinder being connected with conical section, and cylinder is connected with conduit 52,
Soft tissue, blood vessel, muscle, nerve fiber etc. are preferably protected during operation, damage is reduced.
Further, bone component 1 is taken also to include connecting rod 12, connecting rod 12, which is threadedly connected to, takes bone cylinder 11, detachable knot
Structure, is easy to use.
Further,：Bone component 1 is taken also to include the pinning 6 for being used to lock connecting rod 12, connecting rod 12 is provided with and pinning
6 lockholes 7 being engaged, lock onto protection guiding bar 5 by pinning 6 and the mating reaction of lockhole 7 and take in bone component 1, make protection
Guide bar 5 more firm and easy to disassemble.
Further, take and be provided with side opening 9 on bone cylinder 11, taken during bone is taken pressure in bone cylinder 11 can than larger,
Cause cancellous bone to be difficult to receiving and completely take bone cylinder 11, side opening 9 can play a part of deflation, make to take the pressure reduction in bone cylinder 11, just
Accommodated in cancellous bone and completely take bone cylinder 11, side opening 9 also helps the observation of doctor will take the cancellous bone in bone cylinder 11 to take out with being easy to.
Further, the diameter of a circle that the point of a knife of several serrated knifes is surrounded is more than the internal diameter for taking bone cylinder 11 so that cutting
The radius of the bone got off be more than take bone cylinder 11 internal diameter, make to be squeezed into take bone cylinder 11 in, take bone cylinder 11 in cancellous bone more
Fastening, makes to take the cancellous bone in bone cylinder 11 to be easily broken off and separate with ilium main body, the cancellous bone taken out, which is stored in, takes bone
In cylinder 11.
Further, one end of pilot pin 4 is provided with tip, and tip bottom is provided with barb, enables the clinician to simple easily
Ground takes the position of bone needed for pilot pin 4 is inserted, reach the effect of precise positioning, and acquired cancellous bone can be hooked in into positioning
On pin 4.
Further, in addition to locking system 2, connecting rod 12 and handle 3 are connected by locking system 2, are easy to take bone object
Dismounting, convenient to reuse, wherein locking system 2 is prior art, does not make to tell about in detail herein.
Further, the hand grip portion of handle 3 sets flexible sheath, makes doctor more easily comfortable in operation.
Take installation and the operation principle of bone object：The conduit 52 of protection guiding bar 5 is inserted into the connecting rod 12 for taking bone component 1
Interior, the conical section of the protection first 51 of protection guiding bar 5 exposes the outside for taking bone 11 serrated knifes of cylinder, passes through the lockhole in connecting rod 12
7 lock protection guiding bar 5 with the mating reaction of pinning 6, take bone component 1 to be snapped in the locking system 2 of handle 3 by connecting rod 12
It is interior, formed and complete take bone object.During operation, doctor, which is first passed through needed for pilot pin 4 is inserted, takes the position of bone to be positioned, and hooks
The bone to be taken, then taking bone object to pass through pilot pin 4, and is slided along pilot pin 4, when the protection first 51 of protection guiding bar 5
When touching cancellous bone, pinning 6 is opened, protection guiding bar 5 is unclamped, continues slip and takes bone object, protection first 51 touches cancellous bone
It can fall back on and take in bone cylinder 11, take the serrated knife of bone cylinder 11 to continue while rotating handle 3 when touching cancellous bone, manually or electrically
Forward slip, handle 3 is driven by the effect of locking system 2 takes bone component 1 to rotate, and when taking bone 11 rotation of cylinder, its front end is sharp
Several serrated knifes bone is cut, and the cancellous bone after incision be contained in take in bone cylinder 11, will be taken after taking bone cylinder 11 full
Bone object or so teeters, in the presence of several sharp serrated knifes, takes the cancellous bone in bone cylinder 11 can be with ilium master
