Abstract
The invention relates to a guide mechanism used for an orthopedic operation. The guide mechanism comprises a collimator tube and a guide tube. The guide tube is sleeved and connected with the collimator tube. The guide pipe is composed of a first straight part, a bent part and a second straight part which are sequentially connected. The guide mechanism is simple in structure and reliable in performance, the guide mechanism can process the opposite site after entering a spinal from a single side in a spinal operation, the operation difficulty is lowered, the operation time is shortened, and pains of patients are reduced.
Description
Technical field
The present invention relates to manufacture technology field of medical appliance, particularly a kind of bone surgery guiding mechanism.
Background technology
Bone surgery is spinal operation particularly, often needs from side approach process to pleurocentrum or intervertebral space, as row TLIF perform the operation time, in order to can from one-sided approach process offside intervertebral space.Existing method first uses the same side clearance of straight shape instrument process, re-uses the process of elbow instrument to side clearance; For another example during row balloon kyphoplasty, in order to realize resetting to whole vertebral body and fill bone cement, existing method be from both sides pedicle of vertebral arch puncture respectively laggard horizontal reset and fill bone cement.No matter be use straight shape, elbow instrument process intervertebral space, or bilateral vertebral pedicle puncture is to corpus vertebrae replacement and filling bone cement, all extends operating time, increases operating difficulty, increase patient suffering.
Summary of the invention
The object of the invention is the defect overcoming prior art existence, provide a kind of structure simple, dependable performance, spinal operation can be made can to process offside after one-sided approach, reduce operating difficulty, reduce operating time, reduce the bone surgery guiding mechanism of patient suffering.
The technical scheme realizing the object of the invention is: a kind of bone surgery guiding mechanism, has collimator tube and guide pipe; Described collimator tube is socketed in outside guide pipe; Described guide pipe is made up of the first craspedodrome portion connected successively, bending section and the second craspedodrome portion.
Guide pipe described in technique scheme be the Nitinol guide pipe of superlastic condition.
Described in technique scheme, the austenitic transformation finishing temperature Af of Nitinol guide pipe is 5-15 DEG C.
After adopting technique scheme, the present invention has following positive effect:
Structure of the present invention is simple, and dependable performance, can make spinal operation can process offside after one-sided approach, reduce operating difficulty, decrease operating time, reduce patient suffering.
