Description
Technical field
This utility model relates to the therapeutic device of a kind of spinal surgery, and specifically a kind of work angle is variable and do not block the articular process osteotome in the image visual field.
Background technology
In the both sides of each vertebra of lumbar vertebra, there is the osseous tissue projected upwards a pair, be called superior articular process, also have a pair downward projection of osseous tissue, be called inferior articular process. Between adjacent two vertebraes, the position of a pair articular process of homonymy is mutually corresponding up and down, constitutes a zygapophysial joints, therefore, often has a pair zygapophysial joints between adjacent two vertebraes. Zygapophysial joints constitutes the nerve root of the rear wall of intervertebral foramina, cervical region and waist to be passed through from the front of zygapophysial joints, therefore, when there is bony spur when intervertebral disc or zygapophysial joints generation regression hypertrophy, is easy for pressuring neural root, makes Principle of Pain unbearably. The mode of operative treatment is usually removal bony spur or prominent disc tissue, and employing minimal invasive operation is a kind of therapeutic modality more advanced at present, and international vertebral column minimally invasive surgical field has been recognized that foramen intervertebrale lens dominating in this field at present.
Smooth enforcement is expected in foramen intervertebrale lens operation, and the accurately implantation of working column (also known as " directed sleeve pipe " or " service aisle ") is a key of operation success or failure. Intraspinal tube is entered into owing to working column requires over this slype of intervertebral foramina; therefore; patient is had to the situation of lumbar vertebra congenital dysplasia or regression hypertrophy etc.; operative approach will be formed stop by the hypertrophy sclerotin at articular process place; cause that working column cannot be implanted to correct position and make operative failure; more have the patient of pressuring nerve because of intervertebral foramina stenosis, pathological factor that the sclerotin of articular process hypertrophy inherently causes a disease and need fully to excise when operation.
For solving the stop that working column is entered by articular process sclerotin, be clinically at present use the apparatus such as trepan or bone drill, when approach, the osseous tissue at articular process place is carried out thin layer grinding (now foramen intervertebrale lens is but without putting into, operation carries out under not having the visual visual field, there is bigger operational risk), the sclerotin ground away is very thin, thickness is within 0.5mm, to expand the space that working column enters. When needing more excision articular process sclerotin, then need to use High speed drill under mirror that articular process sclerotin is abraded, or use osteotome under mirror to cut. Even if but it is equipped with under the mirror that price is high abrasive drilling system, it is still extremely difficult in practical operation. Because abrasive drilling or osteotome are all entered by the narrow and long path being incorporated within foramen intervertebrale lens under mirror, and foramen intervertebrale lens is all rigid structure together with the working column outside it, after under mirror, abrasive drilling or osteotome enter, the mobility of its work head end is very little, although some design is by abrasive drilling under mirror or osteotome head end slight curve, but the limitation of bending, otherwise apparatus just cannot insert in the path of foramen intervertebrale lens at all. Simultaneously because the path of inserting of foramen intervertebrale lens inherently deviates from the direction of articular process, thus just often there is operative doctor it can be seen that articular process sclerotin but be exactly grind less than or cut a hole the difficult situation less than sclerotin. If attempting the direction of operating changing apparatus, just only have under brute force and press service aisle and foramen intervertebrale lens therein, result of which, not only effect is extremely limited, but also there is great risk and danger, because the lighter is likely to result in the damage of apparatus, severe one can cause the damage of patient's vital tissue structure.
In sum, causing the main cause excising articular process sclerotin difficulty under foramen intervertebrale lens, in that current foramen intervertebrale lens is the different systems such as imaging, lavation, operation to be combined, imaging system and operating system restrict mutually, it is thus impossible to be effectively taking place the deep operation of articular process.
