Description
Technical field
It is the present invention relates to medical instruments field, and in particular to a kind of cutting tool in for intervertebral disc operation, i.e., a kind of
Disc tissue once integrally cuts, intervertenral space shaping cutter.
Background technology
In spinal operation, with the deep and ancillary technique such as Intervertebral disc fusion technology to backbone pathological study not
Disconnected progress, the excision of interverbebral disc soft tissue, the cleaning formation of regular interbody space are adapted to completely as far as possible with bone grafting fusion cage
Ideal space, increasingly become a highly important link of successful surgery.
But due to the special position residing for interverbebral disc, human body it is most deep position and the surrounding that completely embeds it
Barrier, just like one without the room that door is windowless, surrounding is completely closed." ceiling " and " floor " is all hard hone lamella, its
The major axis of orientation insertion body, and at all without entrance, attempt to dig entrance even artificial, do not have at all " construction " yet
" scope of operation ", 360 ° of surrounding is tightly wrapped up by thick " fibrous ring ", just looks like the leather that multiple-layer stacked gets up, and positioned at body
" axle center " at the center of long axis of body, actually human bearing's axle, and the space in it is filled up completely by " nucleus pulposus " tissue.
Nucleus pulposus (Nucleus pulposus) is the agglomerate of whippy semi-liquid-like, just like gelatin, possesses special
" creep properties " mucoid material, its composition 70～90% be moisture content, remainder：Proteoglycans
(proteoglycan) 65% is accounted for, collagen (collagen) accounts for 15～20%, and forms the viscous dense sample material agglomerate of half liquid
(semifluid mass of mucoid material), its special " creep properties " first appears as flexible elasticity.Institute
The position at place, is " gigantic ", carry from " ceiling " (the lower soleplate of upper bone centrum) stress (body weight and
The acceleration of gravity that eminence falls), compression after being absorbed has as a spring, then the release uniformly releived, by stress
It is delivered to " floor " (the upper soleplate of the next bone centrum)；Meanwhile, " nucleus pulposus " tissue between each sections, is again human body
The maximum organ entirely without vascularity (avascular) of interior single volume, its nutrition and metabolism are by tight with it
Touch the tactile dispersion and permeability of soleplate up and down and obtain and complete.
Therefore, with advancing age, or under the undesirable element effect of other stress excessive loads, it will occur aging
Decline；Once and denaturation, be without image of Buddha part other tissue, as skin, muscle, repaired by regenerating.Therefore, when
After its function decay, intervertenral space is necessarily caused to become narrow, " ceiling " close " floor ", stress loses buffering and temporarily breathing,
And rigid direct transmission is gradually become, so as to cause the plain epidemy reason of the unstability dislocation of vertebra section, osteoproliferation, compressing spinal nerve etc.
Change.
And effective solution, exactly the disc tissue of regression is removed as far as possible, sufficient space is regenerated, will be existing
The fusion device of generation technique manufacture inserts this space, parallel bone grafting fusion so as to recover stable.Nucleus pulposus are removed, is set up and is closed
The regular upper and lower interpyramidal space of reason, makes the fusion device of feeding in the position of reasonably stability, is the key step of successful surgery
Suddenly.
But as previously described, because the particularity of the composition of nucleus pulposus, and its disguise of present position, current method
And apparatus, i.e., intervertenral space cannot be directly entered, ceiling and floor are carried out intuitively " cleaning ", disposable entirety to be difficult to again and is removed
Bulk tissue, only in circular fibrous ring " wall " uplifting window, with apparatus " curet (curet) and the nucleus pulposus clamp of Global prevalence
(protractor or tubutorry) piecemeal excavation from inside to outside removes.
" curet ", especially such as the angled little spoon of long handle, the edge of spoon puts the first edge on a knife or a pair of scissors, spoon and handle angulation, progressive from 0 ° to 90 °
Change, size also seriation." nucleus pulposus clamp " puts the first edge on a knife or a pair of scissors such as the beak of bird, the edge for closing up especially, and the two is existing whole world spinal surgery
Only " sharp weapon " are purged nucleus pulposus this committed steps in doctor's hand, during operation, i.e., can only alternately and repeatedly by curet
Send into from window, after touching up or down soleplate, along one spoonful scoop out of its plane one spoonful, or " nucleus pulposus clamp " is sent into flatly
Sting out, translation-angle alternately comes and goes, time and effort consuming, it is difficult to clean；And the viscosity due to nucleus pulposus and creep properties, forever
Also a regular required solid space is unable to reach, especially rectangular parallelepiped space, therefore, the fusion device position being subsequently sent to
Put improper, loosen, shift, or even dislocation, become postoperative much severe complications of puzzlement doctors and patients.
In addition, the drag hook commonly used in existing surgical operation mainly has two big class.A manpower structures, mainly proper angle and
Comfortable handle.By assistant by the high stability lasting drawing of muscle power, to some privileged sites, it is desirable to which assistant has to spy
Different position standing hour is to a few hours, even tens of hours, is really a kind of hard muscle power suffered untold misery for assistant
Work, also usually due to forced position and continue firmly and occur muscle cramp twitch, cause visual area movement change it is unclear, and with
When cause the complaint of intent patient, or even abuse, berate.This is quotidian in any operating room in the whole world
Scene, is also the only way which must be passed of any one ripe hardships course of surgeon's growth！Unfortunately, so far this situation is not yet
Obtain radical change.In all kinds of operations, in also a considerable amount of privileged sites operations, this traditional " drawing is still adopted
Hook " pattern, and can't help the figure for making one usually to emerge " the auspicious son of camel " that " putting up with hardships " in brain！B frame for movements.Pin
To above-mentioned reality, nearly two during the last ten years, and increasing " self-retractor " comes out.So-called " self-retractor ", is exactly to extend
To external drag hook handle, various adjustable frame for movements (framework, bolt, tooth etc.) in connection, by rotation, are made between two handles
Distance increase in vitro, so that the drag hook blade being placed in otch separates to both sides, exposes the visual area in deep.But no matter what
Frame for movement is planted, the barrier of frame-type (depending on the width for neglecting otch requirement greatly of framework) is formed around all inevitable otch in vitro
Hinder, if requiring that four sides is pulled open and blocked, hinder and occupy space and increase therewith, especially in some narrow positions, such as neck, sudden and violent
It is inevitable to have tied up the confined space required during the bimanualness of otch top again while the dew limited visual area in deep, increased hand
The difficulty of art, tests the skill of patient's both hands, directly affects the quality of operation.Even if pull open on four sides around otch simultaneously,
But the inadequate natural endowment of the width due to blade, cannot completely block the normal structure of periphery, so that it is constantly from drag hook at all
Swell in the gap of blade, clamp-on visual area, and disturb the sight line of patient；Simultaneously as be directly exposed in visual area, objectively
Increased when the hand-held sharp instruments formula electric knife of patient, once accidentally drop, the potential risks at any time for being cut or burning, so that
Patient is all the time in the condition of " as though treading on thin ice, feel like standing upon the edge of an abyss ".
In sum, there is problems with prior art：In intervertebral disc operation, existing operation tool is difficult to obtain institute
The solid space of needs.
