Description
Technical field
The present invention relates to medical instruments field, and particularly a kind of scoliosis way of escape corrective procedure visual area panorama is stable aobvious
Reveal device.
Background technology
The present invention relates to medical instruments field, and in particular to one of most long otch of mankind's operation back median line, from nape
The stringer otch in portion to stern line portion, the fully open one kind appeared under state of especially whole back deformity backbone effectively auxiliary and dimension
Hold the apparatus that the clear panorama of operating field stably appears.
Scoliosis (Scoliosis) global incidence about 1% or so, per capita radix count, potential patient is only in
State is just counted in terms of necessarily.It is endangered, and except back outward appearance is uneven, " gong pot " deformity is caused outside patients ' psychological obstacle, severe patient
Splanchnocoel volume can be caused constantly to compress reduction, important organ is squeezed until function is lost and fatal, its unknown etiology as yet, nothing
Method is prevented and radical cure, and unique treatment means are exactly once to find, before severe deformities are developed into, timely operative correction.Half
Since individual more centuries, mankind's operative correction technology, tremendous improvement is obtained, the epoch of the accessible operation of full backbone has been entered, makes
Restitution factor improves constantly, but during this unique treatment method, full spinal operation, an existing brass tacks all the time
But do not improve effectively all the time, " blank " for having formed and having researched and solved of even " being accustomed to ".
First, the preferable of lateral bendings deformity for the most of insertion Thoracolumbar total lengths of realization is corrected, it is necessary to is appeared almost
Whole thoracic vertebraes (12 section) and part lumbar vertebrae (1-3 sections), will realize and fully appear, it is necessary to do length length along trunk dorsal midline
Otch, it may be said that be the most long otch of current mankind's operation, this is unique side of the inevitable realization from the back exposure backbone back side
Formula.However, due to the deformity of scoliosis, this central long otch both sides of stringer is cut open the soft tissue of separation, and body surface must
In different planes, the inevitable high projection in side of pleurapophysis is bent, the height fall of otch both sides soft tissue is formed, produces concave side
It is low flat, the drop of the high protuberance in convex side.Meanwhile the side of pleurapophysis changing due to several rib arcus costarum radians for being connected with backbone
Become, also necessarily being formed not only has high low head, and surface also necessarily shows the rough cutaneous manifestations of various states, adds
The abundant powerful resilience tension force of muscle group in back, once by these muscle from spinal lamina, transverse process and costal process articular surface
After stripping, the extensive surface of a wound is not only formed, and must strongly be bounced back, is drawn close to the bone face being stripped.Although back is not big
Blood vessel and important internal organs, but in the musculature being stripped, invisible containing naked eyes but intensive abundant capillary
Net.Therefore, during continuous stripping, traction, resilience, by continuous and lasting extensive oozing of blood, it is full of moisture content just like one piece
Sponge, stablized and effective retract and be the only resource for appearing backbone and stopping blooding by the compressing of drag hook.
Since the mankind have the history of surgical operation and operating theater instruments to be developed so far, the soft tissue that otch both sides are cut open is used
Drag hook is retracted, blocked, and is to realize not only to appear operating field but also to the sole mode of soft tissue surface of a wound hemostasis by compression.Therefore, have
The drag hook or retractor of variform structure, basic structure are the blade stretched into otch, there is differently curved radian and shape
Shape, such as sheet, dentation, hook-shaped, and the handle of the outer body surface of otch is extended to, mainly there are two major classes, one kind is drawn by assistant's manpower
Stop handle, lasting drawing, referred to as drag hook assistant, another kind of is to design external extending part with various mechanical structures to be connected, use
The framework of mechanical device, abduction, the fixation of drag hook are realized, be referred to as " self-retractor ", but up to the present, from hundreds of ridges of author
In the practice of post lateral bending corrective procedure, to American-European multinational and Asia surrounding countries are repeatedly joined visit and with the friendship performed the operation on the same stage of going together
In stream, no matter which kind of existing manually or automatically drag hook, include the German drag hooks superior in quality, structure is superior of a variety of famous brands,
Without it is a directed entirely to deformity of spine when after hit exactly the most long otch of human body both sides be contour simultaneously, cohesion heterotonia is big, two
Side is uneven, especially convex side, and surface is just like the special drag hook device of the earth's surface in bumpy mountain region, and various countries practitioner adopts
It is applied in combination with various drag hooks, most common mode is to be provided with joint on external long handle, and it is rack to stretch into otch intra vane
Shape structure, it is both arms clamp type, after front end twayblade teeth stretch into otch, the double long handles in rear are waited to strut and locked, otch both ends
All kinds of manually or automatically drag hooks of a pars intermedia recombinant are respectively put, inadequate generation one is unstable, panorama appears insufficient art
Open country, therefore, in surgical procedure, when each key position local fine anatomical structure need to be appeared, it is necessary to constantly adjust drag hook
Position, changing the direction of drag hook could realize, this has become a normality that once you form a habit, it comes natural to you, once perform the operation in, need
Carry out at least for several times, the adjustment of at most tens of times, the drawbacks of its is clear and definite is：
1. adjustment process every time, it is to the soft tissue (paravertebral muscles rich in the sightless fine capillary network of naked eyes
Group) once loosen, pull the process of compressing again, with the blood of the length of adjustment time, at least tens of milliliters, at most up to a hundred milliliters
It is lost in, as once operation inevitably adjusts repeatedly to tens of times for several times, blood loss about 800ml~2000ml, even more
It is more, therefore, Rachiocampis correction operation, be exactly an one side operation, while the process transfused blood of continuous fluid infusion, transfusion volume is at least
600~800ml, at most thousands of milliliters, this is necessary, and has become the normality for ensuring life security, the whole world in this way,
It can be described as being accustomed to.1/7 or so of human blood percentage of liveweight, such as 70kg body weight, blood about 10kg (10000ml), when losing blood
Amount is more than 1/3, you can haemorrhagic shock, Guo Banshi, then threat to life occurs, and the patient of scoliosis more than 90% is blue or green few
Year, average 40~50kg body weight, in terms of 50kg, the most 7000ml of total blood volume, when blood loss is more than 3000ml, that is, there is life
It is dangerous.Therefore, scoliosis surgery, actual is exactly an operation for taking risks " fighting it out to the bitter end ", and regrettably, these are heavy
Cost, be not direct payment fixes in committed step-correction to deformity of operation, and is consumed in and adjusts drag hook repeatedly,
Compress, loosen, pursuit appears in long otch during the anatomical structure details of each key position, more regrettably, unexpectedly
As normality, every operation, it is intended to wait hospital blood bank to prepare enough the blood volume of abundance, and constantly consumes the extremely limited people in source
Class blood resource.
2. loosening drag hook, displacement every time, stripping, oppressing, pull again, light or heavy machine is inevitably caused once
Tool stimulates and wound, and histocyte microscopic damage pathology has sufficient theoretical proof in pathology of trauma, like no matter appointing
In one war of what form, always it is difficult to avoid that and hurts innocent persons, its consequence is inflammatory reaction after wound, the postoperative back of the body of long period
The different degrees of iatrogenic negative effect that the operation such as pain, musculature fibre modification, scar is brought, and cause everything
Reason, repeated multiple times adjustment drag hook in art, stripping are arisen directly from, drawing, oppresses, loosen, then the certainty constantly repeated
As a result.
Kind more than 3. manually, self-retractor be applied in combination, on the one hand making operating table periphery excessive personnel's occupy-place, (2-3 names are drawn
Hook assistant) and crowded, the mechanical device occupy-place of the excessive different aspects in another aspect operating field overhead, influence and disturb in various degree
The sight of patient and fine technical operation.
4. the versatile material of existing drag hook, being medical stainless steel, surface is smooth, and formation multiaspect is reflective under shadowless lamp,
Often dazzle the eyes patient and influence observation of the interference to anatomical detail in visual area and recognize.
