A kind of stable device for exposing of scoliosis way of escape corrective procedure visual area panorama

Technical field

The utility model relates to medical instruments fields, and particularly a kind of scoliosis way of escape corrective procedure visual area panorama is steady Determine device for exposing.

Background technique

The utility model relates to medical instruments fields, and in particular to one of mankind's operation longest notch back median line, from Stringer notch of the nape of the neck to stern line portion, the fully open one kind appeared under state of especially entire back deformity backbone effectively auxiliary And the clear panorama of operating field is maintained to stablize the instrument appeared.

Scoliosis (Scoliosis) global incidence about 1% or so, radix counts per capita, and potential patient is only in State just counts in terms of necessarily.It is endangered, and except back appearance is uneven, " gong pot " deformity is caused outside patients ' psychological obstacle, serious person Splanchnocoel volume can be caused constantly to compress reduction, important organ is squeezed until function is lost and fatal, unknown etiology as yet, nothing Method prevention and radical cure, unique treatment means are exactly once to find, before developing to severe deformities, timely operative correction.Half Since a more centuries, mankind's operative correction technology has obtained tremendous improvement, has entered the epoch of the accessible operation of full backbone, make Restitution factor is continuously improved, but during this unique treatment method, full spinal operation, an existing brass tacks always But do not improve effectively always, " blank " for having formed and having researched and solved of even " being accustomed to ".

Firstly, the ideal correction of the lateral bending deformity to realize most of perforation Thoracolumbar overall lengths, it is necessary to appear almost Whole thoracic vertebraes (12 section) and part lumbar vertebrae (1-3 section), will realize and sufficiently appear, it is necessary to do a length length along trunk dorsal midline Notch, it may be said that be the longest notch of current mankind's operation, this is unique side of the inevitable realization from the back exposure backbone back side Formula.However, this long notch two sides of central stringer is cut open the soft tissue of separation, and body surface must due to the deformity of scoliosis In different planes, it is bent the inevitable high protrusion in side of pleurapophysis, the height fall of notch two sides soft tissue is formed, generates 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 cage arcus costarum radians for being connected with backbone Become, also necessarily being formed not only has high and low fall, and surface also necessarily shows the rough cutaneous manifestations of various states, adds The powerful rebound tension of back muscle group abundant, once by these muscle from spinal lamina, transverse process and costal process articular surface After removing, the extensive surface of a wound is not only formed, and must strongly bounce 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 capillary abundant Net.Therefore, during continuous removing, retracting, springing back, by continuous and lasting extensive oozing of blood, it is full of moisture content just like one piece Sponge, stablized the effective compressing retracted and lean on drag hook, be the only resource for appearing backbone and stopping blooding.

Since the mankind have the history of surgical operation and surgical instrument to be developed so far, the soft tissue that notch two sides are cut open is used Drag hook is retracted, is 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.For this purpose, having had The drag hook or retractor of variform structure, basic structure are the blade protruded into notch, there is differently curved radian and shape Shape such as sheet, dentation, hook-shaped, and extends to the handle of the outer body surface of notch, mainly has two major classes, one kind is drawn by assistant's manpower It stops handle, lasting to pull, referred to as drag hook assistant, another kind of to be connected to design external extending part with various mechanical structures, use The frame of mechanical device realizes outreach, the fixation of drag hook, referred to as " self-retractor ", but up to the present, from hundreds of ridges of author In the practice of column lateral bending corrective procedure, to American-European multinational and Asia surrounding countries repeatedly joins 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, the Germany including a variety of famous brands is superior in quality, drag hook that structure is superior, Hit exactly human body longest notch after when without a directed entirely to deformity of spine two 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 mountainous region, and various countries practitioner adopts It is applied in combination with various drag hooks, the most common mode is to be provided with joint on external long handle, and protruding into notch intra vane is rack gear Shape structure is both arms clamp type, and after front end twayblade teeth protrude into notch, the double long handles in rear wait strutting and locking, notch both ends All kinds of manually or automatically drag hooks of a middle part recombinant are respectively set, 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, the direction for replacing drag hook is just able to achieve, this has become the normality that once you form a habit, it comes natural to you, in primary operation, needs Lack then for several times, more then tens of secondary adjustment, clear drawback is:

1. adjustment process every time 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 length of adjustment time, few then tens of milliliters, more then up to a hundred milliliters of blood It is lost, as primary operation is inevitably adjusted to tens of times repeatedly for several times, blood loss about 800ml~2000ml, even more It is more, therefore, Rachiocampis correction operation, be exactly an one side operation, while continuous fluid infusion blood transfusion process, transfusion volume lacks then 600~800ml, more then 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 weight, blood about 10kg (10000ml) works as blood loss More than 1/3 haemorrhagic shock can occur for amount, Guo Banshi, then threat to life, and 90% or more patient of scoliosis is green lacks Year, average 40~50kg weight, in terms of 50kg, the most 7000ml of total blood volume have life when blood loss is more than 3000ml It is dangerous.Therefore, scoliosis surgery, practical is exactly the operation for taking risks " fighting it out to the bitter end ", and regrettably, these are heavy Cost, not being direct payment fixes the correction of deformity in the committed step-of operation, and is consumed in and adjusts drag hook repeatedly, It compresses, loosen, pursuit appears in long notch during the anatomical structure details of each key position, more regrettably, unexpectedly As normality, every operation is intended to that hospital blood bank is waited to prepare enough sufficient blood volume, and constantly consumes the extremely limited people in source Class blood resource.

2. loosening drag hook every time, displacement, removing, oppressing, pull again, primary light or heavy machine is inevitably caused Tool stimulation and wound, histocyte microscopic damage pathology has sufficient theoretical proof in pathology of trauma, like no matter appointing It in one war of what form, is always difficult to avoid that and hurts innocent persons, consequence is inflammatory reaction after wound, the postoperative back of long period The different degrees of iatrogenic negative effect of the operation bring such as pain, musculature fibre modification, scar, and cause everything Reason arises directly from repeated multiple times adjustment drag hook in art, removing, drawing, oppresses, loosens, then the certainty constantly repeated As a result.

More than 3. kinds manually, self-retractor be applied in combination, on the one hand making operating table periphery excessive personnel's occupy-place, (2-3 are drawn Hook assistant) and crowded, the mechanical device occupy-place of the excessive different level in another aspect operating field overhead, it influences and interferes in various degree The sight of patient and fine technical operation.

4. the versatile material of existing drag hook is medical stainless steel, surface is smooth, and formation multi-panel is reflective under shadowless lamp, Often dazzle the eyes patient and influences to interfere the observation identification to anatomical detail in visual area.
