Posterior decompression bone grafting.Intervertebral disc fusion material can use Invasive lumbar fusion device, autologous bone and homogeneous allogenic bone, because intervertebral melts
Clutch is expensive, and homogeneous allogenic bone rejection is more, therefore many patients require that selection takes autologous bone（As in autologous ilium and art
The spinous process and vertebral plate bone of excision）It is used as bone-grafting material.It is broken that the clamping such as instrument such as nucleus pulposus clamp is commonly used in the implantation of current bone material
Bone fills in intervertenral space, and this service speed is slow, and time-consuming；Or apply bone grafting instrument, such as a kind of vertebras of Chinese patent CN201701282 U
Between bone grafting instrument, the intervertebral bone grafting apparatus includes funnel and stamp stem, and described funnel includes bucket body and guide pin bushing two parts, and bucket body is suitable for reading straight
Footpath is 3.5-5cm, and bucket body lower port diameter is 8-10mm, and the angle of bucket body inclined-plane and horizontal plane is 30-45 °；Guide pin bushing is sky
The cylinder of the heart, a length of 12-15cm；Stamp stem includes shaft and handle, and shaft is solid cylinder, the guide pin bushing inwall with funnel
It is fitted close to and slides up and down.A kind of bone grafting instruments of Chinese patent CN202537631 U, including bone grafting body, piston body, the plant
Bone object body is hollow column structure, and piston body is located in bone grafting instrument body, and there are bone grafting body handle, institute in the bone grafting body rear end
There is piston body handle piston body rear end.And need to carry out intervertebral fusion operation in lumbar spinal stenosis patient, but such patient is mostly
Gerontal patient, the height degenerated of intervertenral space is narrow, using above-mentioned bone grafting mode, it is impossible to abundant, substantial amounts of bone grafting, and influences art
Intervertebral fusion effect afterwards.In addition when bone material in funnel is pushed at bone grafting and tamped using stamp stem, because of the guide pin bushing of funnel
Front end is opened completely, and stamp stem breaks through anterior longitudinal ligament damage abdominal cavity blood vessel and internal organs when firmly excessive, and firmly too small can make to lead
Cover lower end to block, and influence bone grafting effect.
The content of the invention
The purpose of the present invention is to overcome drawbacks described above there is provided a kind of intervertebral pulling bone grafting instrument, is suffered from applied to stenosis of disc space
Person can increase bone grafting amount, it is ensured that bone grafting syncretizing effect, while preventing that stamp stem from exerting oneself macrolesion intra-abdominal hemorrhage pipe and internal organs.
The present invention is to achieve these goals, as follows using technical scheme：
Intervertebral pulling bone grafting instrument, is made up of dilator, bone grafting funnel and tamper, and the dilator includes the first transmission arm, second
