Description
Technical field
This utility model belongs to surgical operating instrument, relates to surgery spinal column operating theater instruments, relates generally to the apparatus that a cover is used for breast lumbar vertebra anterior approach.
Background technology
Accidents such as traffic, industrial injury, high falling cause spinal fracture easily, and wherein 90% is lumbar vertebra compression fracture.For this type of fracture, particularly serious bursting fracture, the expectant treatment poor effect often needs operative treatment.
At present, operative treatment comprises anterior approach and posterior approach.Advantages such as back road technique is simple owing to approach, complication is few, short term efficacy is remarkable become the most frequently used operation method of present treatment lumbar vertebra compression fracture.It realizes that by strutting before and after intervertebral space, the tension ligament complex vertebral fracture resets and reduces pressure.But, for the case (surpassing 50%) of the serious compression of vertebral body, the bone trabecula fracture that the inner existence of vertebral body is more serious, the instantaneous axis of following simultaneously makes disc tissue charge into vertebral body by disruptive soleplate to the violence effect.Though back road technique can make the vertebral body outward appearance obtain more obviously to improve, but disc tissue that it is inner and trabecular bone structure can not finely reset, therefore form the consequence of similar limb fracture site " soft tissue embedding ", have a strong impact on the union of fracture of vertebral body inside, cause vertebral body long term " change of Ovum crusta Gallus domesticus sample ".In addition, strut in the intervertebral space process in the way of escape, peripheral soleplate fracture can be resetted along with the fibrous ring tension, still, for the soleplate fracture of middle section, because it lacks fibrous ring and adheres to, therefore can not obtain satisfied resetting.And the change of soleplate form will finally cause the pathologic of intervertebral space stereochemical structure to change, intervertebral disc changes and the generation creep in order to adapt to the intervertebral space form, make it lose the effect of buffering and absorbing load gradually, causing acting on epicentral stress increases, cause that hindering the vertebra height loses, generation carrying out property kyphosis deformity in long term and low-back pain.Again it, for the case of part canalis spinalis occupy-place, back road technique may enlarge the canalis spinalis space by the excision vertebral plate, has realized the order point of indirect decompression.But, if serious occupy-place of canalis spinalis or bone fragments in vertebral canal upset, this indirect decompression effect is unsatisfactory, and the modus operandi of excision vertebral plate not only causes the epidural cicatrization, and will further destroy the integrity of posterior column structure, weaken the stability of spinal column.Before center pillar bear about 70% spinal column load, in serious lumbar vertebra compression fracture, center pillar damage before normal existence the, and be positioned at the latter half of spinal column center of rotation of intervertebral disc and also often follow fracture and shift.If column stability and center of rotation can not recover during fracture surgery was preceding, the load that will cause being carried on the way of escape internal fixation increases unusually, causes the generation of complication such as the disconnected rod of broken nail.
Road technique excision under direct-view causes the pressure thing before the spinal column, and pressure relief ranges is thoroughly extensive, and canalis spinalis enlarges reliable, and does not disturb posterior column structure stability; Do not need the tractive spinal cord in the decompression process, nerve injury danger is little; Simultaneously, hinder vertebra, eliminated problem by bone trabecula and soleplate fracture does not reset, disc tissue embeds vertebral body etc. causes by inferior full excision; The use of fit structure bone grafting and preceding road internal fixation device, the center of rotation of middle column stability and spinal column before having recovered.Therefore, seriously compressing (leading edge high compression surpass 75%), the obvious occupy-place of canalis spinalis (surpassing 50%), serious kyphosis deformity (greater than 30 degree) or fracture time for the part vertebral body surpasses breast lumbar vertebra body such as 2 weeks and splits the fracture case cruelly, still be that aspect such as late result is considered from operation decompression, union of fracture, biomechanical stability no matter, preceding road technique all has remarkable advantages.
Though, anterior approach has above-mentioned advantage, but also there have been some open defects in traditional anterior approach, as: big, the sick vertebra difficult exposure of operation wound, intraoperative hemorrhage is many, operating time is long, overhaul difficulty etc., these technical bottlenecks have seriously restricted its extensive use clinically, some basic hospitals particularly are often with the final therapeutic scheme of posterior approach as all lumbar vertebra compression fractures.

3, the operative approach of specimen and otch are selected
Compare with the way of escape, the road technique risk is bigger, wherein in the majority with vascular complication before the breast lumbar vertebra.Most of complication are relevant with operative approach, therefore select suitable approach very crucial for reducing postoperative complication.In cadaver sample, approach on the left of our the conventional selection.But clinically, need consider factor: the right side exposes and exists liver to disturb, and the thin matter of the caval vein wall of homonymy is crisp, and tractive damages easily, damage back anthemorrhagic difficulty; And vertebral body left side organ retracts easily, and factors such as obviously easy identification of aorta pollex and the anti-tractive of wall thickness.Therefore, can select right arm reclining, the left side approach.But should consider the left side approach when following situation is arranged carefully: (1), focus are positioned at the right side, and difficulty is removed in the left side; (2), previously there is history of operation in the left side, the tissue adhesion is serious, the difficulty and the risk of second operation are bigger; (3), patient age is big, the calcific aortic severe patient, tractive may cause the arterial wall accident of breaking in the art; (4), need the thoracic cavity route, right lung exists pathological changes or damage simultaneously, and the normal person of left pulmonary function.For breast
12The above sections pathological changes of vertebral body adopts approach (or thoracic cavity approach) outside pleura; Breast
12Below the vertebral body, through the retroperitoneal space approach.
For waist
1During operation, traditional operation adopts thoraco-abdominal incision, needs to cut diaphram, enters the thoracic cavity, and is bigger to the physiological function interference, is unfavorable for post-operative recovery.We select breast
12The rib route cuts left diaphram foot, peels off breast
12The parietal pleura in vertebral body the place ahead, and make full use of waist bridge expansion exposed space, realize not advance the purpose of breast.
4, the using method of operative region exposure and long handle drag hook I
Erect the waist bridge after specimen is lain on one's side, it is curved in the wrong to make lumbar-thoracic spine be the left side, enlarges the intercostal space, left side, increases the distance of arcus costarum and crista iliaca, for surgical exposure creates conditions.No matter be into breast or the outer route of peritoneum, different with traditional otch, all rise from the oblique front lower place of posterior axillary line near the anterior axillary line, incision length varies with each individual, about about 13～18cm.Operator is positioned at the veutro of cadaver sample, in the favourable Rhizoma Atractylodis Macrocephalae during operation of spinal canal decompression and internal fixation to the affirmation of canalis spinalis position.Thoracic cavity approach routine is not excised rib, enters from the intercostal of nearly two sections of sick vertebra, and breast struts rib interval up and down.Be used thorax dilator and two in the art long handle drag hook I (referring to Fig. 1), two vertebral bodys up and down that the most advanced and sophisticated I of its drag hook is fixed in the disease vertebra; Head 2 is broader, can push soft tissue open; Body 3 is longer, is suitable for the dark characteristics of anterior approach exposure position; Be bundled in breast support handle by tail end circular hole 4 usefulness sterilization binders, retract the purpose that the lobe of the lung appears disease vertebra operating field to reach.
5, the using method of processing of sections tremulous pulse and long handle periosteal elevator II
Because surrounding tissue is fine and close relatively, separate and ligation sections tremulous pulse process in may cause and damage and cause hemorrhagely that so processing of segmental blood vessel is one of difficult point of breast waist anterior approach.Traditional anterior approach method often needs ligation to handle to comprise on the disease vertebra hypocentrum with three interior segmental vessels, not only time-consuming but also effort.We find when summing up the experience of operation in the past, and only the sick vertebra sections of ligation tremulous pulse can be finished the decompression bone grafting and the internal fixation operation on preceding road.In specimen, use two special long handle periosteal elevator II (referring to Fig. 2), circle is blunt for its head 5, is used to oppress blood vessel; Body 6 is longer, is suitable for the dark characteristics in anterior approach position; Afterbody is a handgrip 7, with the tapered structure in body 6 junctions, is suitable for human both hands and clenches fist and hold the anatomical features of thing.After the compressing segmental vessels, proximal part is fully free to give dual ligation or seam bundle, and the distal end electric coagulation hemostasis.
6, the using method of spinal canal decompression and long handle osteotome III, long handle soleplate curet IV, long handle curet V
Referring to Fig. 3, spinal canal decompression not only difficulty has a big risk, and hemorrhage many, is the key link of spinal column anterior approach.We are confirming that cadaver sample is under the positive lateral position situation, cut off disease vertebra intervertebral disc first half up and down with sharp knife earlier, directly cut the front middle part branch of vertebral body then with long handle osteotome III, its cutter head 8 is a flat, there is not radian, direction is vertical with the specimen trunk all the time during use avoids being strayed into canalis spinalis, and body 9 is longer, meets the dark characteristics in breast lumbar vertebra anterior approach position; Afterbody 10 is big than the body cross section, guarantees that hammer more stably knocks.Not being in a hurry earlier when being decompressed to the canalis spinalis antetheca during operation enters canalis spinalis, because in a single day canalis spinalis is opened, may cause the venous plexuses that are difficult to stop hemorrhage more.Patient removing this moment is disc tissue and cartilage endplate up and down.Referring to Fig. 5, long handle soleplate curet IV is used in the processing of disc tissue and cartilage endplate, curet head 11 is the ellipsoidal structure of hollow, the inside edge is sharp keen, be used to remove soleplate and disc tissue, body 12 is longer, meets the dark characteristics in breast lumbar vertebra anterior approach position, the design of handle 13 surface wave shapes prevents from during use to skid.After soleplate is ready, strut the bone grafting gap with dilator in advance, measure bone grafting length.When the assistant begins to prepare scientific network outside suitable ilium piece or the titanium/bone grafting member body (TSM/ bone grafting member body), use the rear wall that special long handle osteotome III cuts the disease vertebra carefully instead.Referring to Fig. 4, the old fracture person can find a break-through point in conjunction with abrasive drilling between bone rear wall and canalis spinalis, carefully tube wall bone piece and spinal dura mater are separated with long handle curet V then, curet head 14 is a crotch that circle is blunt, be used to separate bone piece and spinal dura mater, bone piece and disc tissue, body 15 is longer, meets the dark characteristics in breast lumbar vertebra Qian Lu position, afterbody is the handle 16 of the tapered structure that is connected with body 15, meets staff more and clenches fist and hold the anatomical features of thing.After separating bone piece and spinal dura mater, extract the sclerite of charging into canalis spinalis, thoroughly carry out the decompression of canalis spinalis antetheca.Find in the use practical operation of long handle curet V that entering spinal canal decompression from the vertebral body rear wall has two advantages: 1, need not appear and excise pedicle of vertebral arch, 2, be easy to difference at the canalis spinalis antetheca of bone and posterior longitudinal ligament and spinal dural soft tissue, therefore look for the breach of canalis spinalis both easy, comparatively safe again herein.Then, after decompression completely, get preprepared TSM/ bone grafting member body, tap down implant bed under the prerequisite in gap and (notice that TSM/ bone grafting member body is unsuitable oversize strutting, in order to avoid insert difficult damaged bone soleplate or go into the side of trackside protruding), confirm TSM/ bone grafting member body after the implant bed position is satisfied, carry out internal fixation and the pressurization of TSM/ bone grafting member body.
In a word, a cover that provides by this utility model comprises the utilization of the apparatus of long handle drag hook I, periosteal elevator II, long handle osteotome III, long handle curet IV and soleplate curet V; Segmental vessels is handled the change of theory and the innovation of spinal canal decompression order and method, reduced conventional breast lumbar vertebra anterior approach to the requirement of otch, shortened operating time, make breast lumbar vertebra anterior approach become possibility as the posterior approach universalness.
