Technical field
The utility model is related to medical instruments field, more particularly to a kind of long inclined-plane bias adjustment locating sleeve.
Background technology
Side way of escape foramen intervertebrale lens technology (TEssYS technologies) is by German Hoogland in utility model in 2002, and this is one
Protrusion ablation techniques under the way of escape transforaminal approach canalis spinalis expert's scope of lumbar vertebrae side are planted, its core is to utilize trepan or bone drill pair
Processus articular superior Partial Resection, carries out intervertebral foramen shaping, places diameter 7.5 or 8mm working columns, intervertebral is placed in working column
Aperture mirror, is extractd, a kind of minimally invasive spine surgical that nerve root Decompression is loosened under scope to disc herniation.
TEssYS technology spiral bone drill operating procedures：Patient takes prone position to obtain lateral position.Had an X-rayed using C arms, according to preoperative X
Line, subject disk target spot and processus articular superior tip line are as line is punctured, with reference to ilium height, transverse process position, patient size
And pedicle of vertebral arch distance appropriateness adjustment Bing determines skin penetrating point, typically apart from center line 8-14cm, head inclines 30 ° to be punctured to front lower.Enter
Anaesthetized at pin mark and puncture path local anaesthesia, processus articular superior.Processus articular superior is passed through in No. 18 lancet punctures, C arms perspective confirmation
Outer rim, normotopia, side position perspective confirm that needle point is located at target (protrusion).As the undesirable use diplopore adjuster in position is carried out
Adjustment, or punched using the TOM pins of Hoogland utility models in processus articular superior, can place seal wire Bing after the satisfaction of position stays
Put, extract puncture needle, soft-tissue expansion is carried out to processus articular superior along seal wire insertion location guide.Used along seal wire insertion and utilize bone
The MaxMoreSpine (from small to large, diameter 4mm, 6mm, 7mm, 8mm) of Hoogland utility models is bored to processus articular superior part
It is ground step by step, carries out intervertebral foramen shaping, Bing places working column.Generally working column ideal position is reverse S-line of Golden sleeve
Distal tip is located on the inside of the walking root of puncture side, not across line between spinous process, and side position is located at centrum through lower in front of processus articular superior
Upper limb afterwards.
TEssYS technological cores are, to processus articular superior Partial Resection, to carry out intervertebral foramen shaping using bone drill.In clinical practice
In we run into problems with：(1) puncture point orientation often has deviation, it is necessary to which fluoroscopic puncture is positioned repeatedly；(2) upper joint is uprushed
Raw, intervertebral foramina stenosis cause that adjustment can only be tapped by TOM pins or coordinate the adjustment of diplopore adjuster, and diplopore adjuster is easily moved
It is dynamic to be adjusted, it is necessary to have an X-rayed repeatedly.(3) TOM pins easily slide in processus articular superior punching hour hands cusp, especially in L5S1.(4)
Small seal wire is put into after punching may be deformed by muscle tone and influence the reaming deviation of directivity, it is not in place, and on the lower side to the rear cause
Nerve root, dural sac damage.(5) intervertebral foramen is tapered into from top to bottom at processus articular superior, easily inclined to abdomen, rostral during grinding
Move.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or implies that the information structure has been existing well known to persons skilled in the art in any form
Technology.
