Compared with the bone drill instrument of the prior art, the beneficial effects of the present invention are: backbone scope 1. can be passed through in bone milling cutter
Camera lens, expand intervertebral foramen on demand under direct-view, precisely, safety.2. the cross section of milling head is designed to half-crescent shape, more just
Just it cuts, improve working efficiency, firmer, resistance to strain.3. handle is that the design of " rudder " sample facilitates grasping.4. there is holder to cover
Drilling rod, facilitate pressurization hold, avoid gloves twist into.The angle and shape of sawtooth, reach quickly the upper and lower articular process abdomen of vertebra,
Outside expand channel purpose, rapidly and efficiently and extremely low risk completion backbone endoscopic surgery intervertebral foramen Plastic operation, mention
High procedure efficiency, reduces the patients surgery time.
The present invention visualizes the duct that bone milling cutter can be such that backbone endoscope lens pass through by setting, changes blind brill sclerotin
Deficiency, allows patient in the case where complete visual, abrades the prominent sclerotin of lower articular on demand, expands forming intervertebral foramen, has
Conducive to precision when improving intervertebral foramen forming, operation risk is reduced, patients surgery time is reduced, mitigates doctor during operation
Pressure.It is furnished with holder outside milling arbor, facilitates patient to hold pressurization, avoid damage to milling arbor.Milling cutter is driven by driving motor
Bar rotation, reduces the labor intensity of operation, improves the degree of automation for boring bone surgical operation.The present invention is inside and outside in milling arbor
Surface is provided with graduated scale, views milling head by graduated scale and bores bone depth, advantageously reduce the number of perspective, mitigates to trouble
The radiation hazradial bundle of person and doctor.
