Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of middle pressure-reduced impaction device of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail: a kind of micro-wound pressure-reduced impaction bone grafting device for combined femoral head necrosis, as Fig. 1, shown in 2, comprise joint Wicresoft drag hook 2, pressure-reduced impaction device 13, little curved curet 8, pressure-reduced impaction device 13 comprises trepan 15, trepan has the positioning pipe 12 of sawtooth comprising right-hand member, have the trepan through hole on the positioning pipe 12, blunderbuss 11 is housed in the trepan through hole, blunderbuss 11 comprises handle 18, the design of handle 18 right sides has blunderbuss bar 10, design has retaining rank 17 between handle 18 and the blunderbuss bar 10, retaining rank 17 are positioned at the left of trepan 15, handle 18, blunderbuss bar 10 is an integral body with retaining rank 17, blunderbuss bar 10 passes the trepan through hole, Wicresoft's drag hook 2 comprises arm-tie 1, the one end design of arm-tie 1 has little crotch 3, little crotch 3 is an integral body with arm-tie 1, little curved curet 8, comprise and scrape the shank of the key 4, the right-hand member of scraping the shank of the key 4 is connected with curet bar 7, the right-hand member design of curet bar 7 has radian bar 6, the design of the right-hand member of radian bar 6 has spoon 5, scrapes the shank of the key 4, curet bar 7, radian bar 6, spoon 5 is an integral body; In the present embodiment, trepan also comprises the trepan pipe 14 in positioning pipe 12 left sides, the design of trepan pipe 14 left ends has handle 16, have the handle through hole on the handle 16, trepan through hole, trepan pipe pore, handle through hole communicate, handle 16, trepan pipe 14, positioning pipe 12 are an integral body, and blunderbuss bar 10 passes handle through hole, trepan pipe pore respectively; In the present embodiment, the radius of trepan pipe 14 is greater than the radius of positioning pipe 12, and blunderbuss can be put into trepan easily, and positioning pipe plays positioning action, and the position of operation is more accurate when making operation; In the present embodiment, joint Wicresoft drag hook 2, pressure-reduced impaction device 13, little curved curet 8 outsides are with pack 9, make micro-wound pressure-reduced impaction bone grafting device for combined femoral head necrosis easy to carry, deposit conveniently.
When using the present invention to perform an operation, epidural anesthesia.Horizontal position, the Ipsilateral buttocks is bed hedgehopping slightly, makes the trouble hip slightly be the hyperextension position.5CM begins under the anterior superior iliac spine, and longitudinal incision is about 3-4CM downwards, cuts skin, subcutaneous tissue and deep fascia successively, notes not damaging lateral femoral cutaneous nerve.Separate to the deep along tensor fasciae latae inner edge and rectus femoris outer rim, through joint capsule inwardly separates and retracts rectus femoris, outwards retracts tensor fasciae latae, appears joint capsule.The crucial incision joint capsule, it is no abnormal to notice during incision that joint fluid and synovial membrane have, and gets the specimen censorship in case of necessity.Insert the neck of femur both sides with joint Wicresoft drag hook and retract joint capsule, appear femur head and neck cross-connecting area front portion.Decompression bone grafting: reduce pressure about deeply 1CM with the trepan in the pressure-reduced impaction device of diameter 1CM in the head and neck junctional area to femoral head direction ring cutting.When in most cases trepan reaches the osteonecrosis district, have tangible resistance and lower sense.Take out trepan, stretch in the hole, strike off sequestrum repeatedly, should strike off cyst wall if any blister cavities with little curved curet, should be soft when under cartilage, scraping bone, available arthroscope inserts bone cavity and observes, and instructs and scrapes bone and prevent to wear out cartilage.Surface of bone has obvious oozing of blood behind the sequestrum scraping.Cut spongy bone in the homonymy crista iliaca, get several lamellar spongy bone earlier and place under the cartilage, the little curved curet of reuse is scraped and is got spongy bone and insert in the bone cavity, uses blunderbuss punching press to beat reality while insert, and bone cavity is full of.Trepan in the reuse diameter 1.2CM pressure-reduced impaction device is got the bone piece that has one deck cortical bone on crista iliaca, embed the vent collar extension, suppresses smoothly, finishes bone grafting operation.Around vent, bore two apertures in case an internal pressure is too high to the femoral head direction with the 1.5MM Kirschner wire; Flushing cleaning joint, exhaustion intraarticular dermoskeleton bits and liquid, the difference layer-by-layer suture edge of a knife, i.e. operation finishes.Postoperative can sit up next day, and the edge of a knife can not held ground walking gradually under the crutches after bitterly, does not preferably bear a heavy burden half a year, and postoperative cooperates treatments by Chinese herbs such as taking the activating blood circulation to dissipate blood stasis kidney invigorating and YANG supporting, and the bilateral hip joint is operator simultaneously, requires to hold after 3 months crutches exercise walking.
The method that we adopt is in the decompression of head and neck intersection, and decompression and sequestrum are removed thoroughly, adopt autologous bone transplanting, has good induced osteogenesis ability, have to experimental results show that fresh autotransplantation bone directly contacts the bone wound surface that blood fortune is arranged, the part implantable bone can directly survive, and can improve reparation speed.We adopt the method for impaction bone grafting, make the bone cavity filling tight, and subchondral bone is had stronger supporting role.The normal part patient intraarticular of finding has more hydrops in the operation, intrinsic pressure increasing can influence the femoral head venous return in the joint, capsula interna is directly cut in this operation, lower intracapsular pressure, help improving femoral head blood fortune, arthroscope directly stretches in the bone cavity and observes, as seen the sequestrum tarnish that is white in color, no trabecularism, no oozing of blood can thoroughly be removed.Simultaneously, can avoid striking off the normal bone tissues of blood confession, it is effective to use the present invention to perform an operation, and is suitable for early stage femur head necrosis patient's operative treatment.
