Description
Technical field
The present invention relates to a kind of bone grafting instrument.
Background technology
Bone tissue is mainly moved on to the position that skeleton defect, needs are strengthened or merged in patient body by bone grafting operation by performing the operation.
And in surgical procedure, often need by bone grafting instrument.Existing bone grafting instrument typically uses bone grafting pipe, in use, Chang Jiang
Bone tissue is positioned over the rear end of bone grafting pipe, then it is removed from the front end of bone grafting pipe by push rod passage bone tissue and reaches shifting
Bony site.But when intervertebral under mirror or percutaneous cervical arc root bone grafting, because bone tissue will hold in the longer path of bone grafting in-pipe
Easily there is the problem of bone grafting difficulty.
The content of the invention
For overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of bone grafting instrument, and it can be convenient under mirror
Intervertebral or percutaneous cervical arc root bone grafting.
To solve the above problems, the technical solution adopted in the present invention is as follows：
Bone grafting instrument, including the outer tube provided with open front, be inserted into outer tube and can be moved axially back and forth along outer tube
Charging ram；The rear end of the outer tube is provided with lever；Be hinged with a handler on the lever, the end of the handler with
The rear end of charging ram is hinged；Install and have elastic component between the lever and handler, the flexible member is used to promote to rotate
Handle is resetted to drive charging ram to reset the simultaneously open front away from outer tube backward.
The flexible leading section of outer tube, be provided with side opening on the tube wall of the elastic front end, the side opening to
Before extend through the preceding surface of outer tube.
The width of the side opening is 2.5mm.
The caliber of the outer tube leading section is more than the caliber at other positions.
A diameter of 5mm push-plate is provided with charging ram front end.
The flexible member is V-type shell fragment.
Compared with prior art, the beneficial effects of the present invention are：
The present invention designs by using the combination of outer tube, charging ram, handler, in use, can be by bone tissue
The leading section of outer tube is placed on through open front, makes charging ram forward impelling by pulling handler, and release using charging ram
Bone tissue carries out bone grafting, can shorten the path of bone tissue movement, be convenient to intervertebral or percutaneous cervical arc root bone grafting under mirror；It is moreover, logical
The structure that outer tube leading section is rationally set is crossed, is also convenient to being put into, elapsing for bone tissue, bone tissue can be reduced and block probability,
Further to improve intervertebral or percutaneous cervical arc root bone grafting bone grafting simple operation under mirror；In addition, its is simple in construction, cost of manufacture compared with
It is low, be advantageous to promote.

Embodiment
Below, with reference to accompanying drawing and embodiment, the present invention is described further, in order to clearer understanding
Present invention technical thought claimed.
As shown in Figure 1, 2, 3, it is the bone grafting instrument of the present invention, including the outer tube 1 provided with open front 12, is inserted into outer tube
In 1 and the charging ram 2 that can be moved axially back and forth along outer tube 1；The rear end of the outer tube 1 is provided with lever 11；The lever 11
On be hinged with a handler 3 so that handler 3 can rotate around pin joint relative to lever 11 under external force, the handler 3
End and the rear end of charging ram 2 be hinged；Installation has elastic component 4 between the lever 11 and handler 3, the flexible member
4 are used to promote handler 3 to reset to drive charging ram 2 to reset the simultaneously open front 12 away from outer tube 1 backward.
In the present embodiment, the flexible member 4 is V-type shell fragment.Certainly, in addition to using V-type shell fragment, the elasticity
Element 4 can also use spring, or torsion spring etc..
Preferably, the 1 flexible leading section of outer tube, side opening 13 is provided with the tube wall of the elastic front end,
The side opening 13 extends through forward the preceding surface of outer tube 1.And when being put into or releasing bone tissue, due to outer tube 1
Leading section has side opening 13, can under external force elasticity expand, so as to be convenient to bone tissue in outer tube 1 being put into and
Release；The leading section elastically deformable of outer tube 1 is additionally, since, it is logical to be also convenient to bone grafting length of the outer tube 1 Jing Guo patient's body
In road.And it is preferable, the width of the side opening 13 is 2.5mm, can facilitate bone tissue disengaging simultaneously, and outer tube 1 of being more convenient for enters
Move back the bone grafting long-channel of patient's body.Wherein, it is additionally provided with the stern notch connected with side opening 13 on the tube wall of the outer tube 1.
Preferably, the caliber of the leading section of outer tube 1 is more than the caliber at other positions.And by using said structure,
Charging ram 2 can be convenient to move in outer tube 1, and can further improve loading and release of the bone tissue in outer tube 1
Convenience.
A diameter of 5mm push-plate 21 is provided with the front end of charging ram 2, to be convenient to promote bone tissue.
In use, user holds lever 11, and before bone tissue is enclosed in into outer tube 1 by open front 12
End；Then outer tube 1 is stretched into the bone grafting long-channel of patient's body, when outer tube 1 reaches bone grafting position, utilizes finger
Pulling handler 3 makes handler 3 be rotated around pin joint, and is moved along by the synchronous drive charging ram 2 of handler 3, finally leads to
Cross charging ram 2 and bone tissue is pushed out to bone grafting position progress bone grafting from open front 12, so as to be convenient to intervertebral or percutaneous under mirror
Pedicle bone graft；And it is to be operated after the completion of, by unclamping handler 3, can make handler 3 flexible member 4 elastic force effect under
Reset, and drive charging ram 2 to reset backward by handler 3, make open front 12 of the charging ram 2 away from outer tube 1.
Above-mentioned embodiment is only the preferred embodiment of the present invention, it is impossible to the scope of protection of the invention is limited with this,
The change and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed scope.
