Overtax one's nerves through surgical doctor learning curve is precipitous, learning cycle is long.During cutting sclerotin reaming, only with the experience of patient
Property operation and X-ray examination guidance, it is difficult to ensure that accuracy and safety in bone drill use process.
Utility model content
The purpose of the utility model is to provide a kind of visualization bone milling cutters, optimize the structure of bone drill, change previous blind brill bone
The deficiency of matter reduces risk when intervertebral foramen forming, improves precision and safety coefficient, reduce the patients surgery time, mitigates doctor
Raw pressure during operation.
The technical solution of the utility model is: visualization bone milling cutter, including protection head, milling head, milling arbor and milling cutter shank,
Protection head, milling head, milling arbor and milling cutter shank are sequentially connected integrated molding, and milling arbor is equipped with EXT scale mark.Bone milling cutter is hollow
Structure is equipped with the duct that backbone endoscope lens can be made to pass through from protection head to milling cutter shank.The inner wall in duct is equipped with interior graduated scale, institute
Interior graduated scale is stated from protection head to 30~80mm long of milling arbor direction signs.
Bone milling cutter is equipped with holder, and holder is sleeved on the outside of milling arbor.The edge that holder is contacted with milling arbor is in
Turnup structure avoids damage to milling arbor.Milling cutter head surface is provided with wear-resistant coating.The diameter in duct is 6.0~7.0mm, milling cutter
Bar outer diameter is 8.0~10.0mm.Milling head is left-hand screw shell end mill structure, convenient fine removing sclerotin.Bone milling cutter is equipped with
Swing handle, swing handle are equipped with antiskid bar, and swing handle is coupled with milling cutter shank.
Compared with the bone drill instrument of the prior art, the beneficial effects of the utility model are: 1. backbone can be passed through in bone milling cutter
The camera lens of scope expands intervertebral foramen under direct-view on demand, accurate, safety.2. the cross section of milling head is designed to half-crescent shape, more
Add and facilitates cutting, improves working efficiency, firmer, resistance to strain.3. handle is that the design of " rudder " sample facilitates grasping.4. there is holder
Cover in drilling rod, facilitate pressurization hold, avoid gloves twist into.The angle and shape of sawtooth reach quickly in the upper and lower articular process of vertebra
Abdomen, outside expand channel purpose, rapidly and efficiently and extremely low risk completion backbone endoscopic surgery intervertebral foramen Plastic operation,
Procedure efficiency is improved, the patients surgery time is reduced.
The duct that the utility model visualization bone milling cutter can be such that backbone endoscope lens pass through by setting, changes blind brill bone
The deficiency of matter, allows patient in the case where complete visual, abrades the prominent sclerotin of lower articular on demand, expands forming intervertebral
Hole is conducive to improve precision when intervertebral foramen forming, reduces operation risk, reduces the patients surgery time, mitigates doctor in hand
Pressure when art.It is furnished with holder outside milling arbor, facilitates patient to hold pressurization, avoid damage to milling arbor.The utility model is milling
Knife bar inner and outer surfaces are provided with graduated scale, view milling head by graduated scale and bore bone depth, advantageously reduce time of perspective
Number mitigates the radiation hazradial bundle to patient and doctor.
