Abstract
The utility model relates to a restorer of bone blocks in a spinal canal, which is an appliance for leading the bone blocks pressing on nerves to be restored after spinal fracture and comprises a restorer head portion, a restorer connection rod and a restorer handle portion. The restorer head portion is connected with the restorer connection rod in welding mode, an included angle reserved between the front side of the restorer head portion and the restorer connection rod is 120 degrees, the restorer is an arc-shaped flat dull head, a coarse face formed by a plurality of dot-shaped particles is arranged on the arc-shaped back side of the head, and the restorer handle portion is in a flat conical-column shape. The restorer of bone blocks in the spinal canal has the advantages of: 1 pressing the bone blocks in the spinal canal, and directly embedding the rear-protruded bone blocks into a pathologically-changed spinal body by adopting an embedding working principle so as to directly restore the bone blocks and directly expand the spinal canal; 2 no longer dragging cauda equine nerve after the rear-protruded bone blocks are directly restore, and causing no damage to the nerve easily; and 3 having small influence on veniplex in front of the spinal canal, being not apt to causing massive haemorrhage and having small secondary harm to patients.
Description
One, technical field
This utility model relates to a kind of bone fragments in vertebral canal positor, is that the bone piece is charged into the bone block reset apparatus that causes the canalis spinalis occupy-place in the canalis spinalis after being used for treating spinal fracture, impels the apparatus of the bone block reset of pressuring nerve, belongs to the medical apparatus and instruments that Orthopeadic Surgery uses.
Two, background technology
Hospital is when the treatment spinal fracture has the case of bone piece pressuring nerve now, and advanced horizontal reset detects when the bone piece is arranged in the canalis spinalis, carries out the embedding pressure with the top rod and resets.When resetting; The top rod is absorbed in the vertebral body easily, sliding easily injures nerve root on every side, blood vessel etc.; Whether the dynamics of suppressing be difficult for is held, and can not well detect the reset case of bone fragments in vertebral canal, reset and then need take out the top rod and detect with nerve probe if detect the bone piece.Prolonged operating time so virtually, increased nerve injury chance, increased amount of bleeding.
Three, the content of utility model
The purpose of this utility model is the defective that exists to above-mentioned top rod, has developed the bone fragments in vertebral canal positor.
The purpose of this utility model realizes like this: it comprises: positor head, positor connecting rod, positor shank; Positor head and positor connecting rod are welded to connect; The front side of positor head and positor connecting rod are 120 °, and it is that arc is flat-shaped blunt nosed, have a plurality of point-like granules to form the matsurface of dorsal part at head arc dorsal part; The positor shank is flat awl cylindricality; Positor connecting rod rear portion is provided with plug, and plug is connected with the positor connecting rod with screw, has sunk head rivet that the positor connecting rod is fixed in the positor shank; The positor shank is made with rubber wood timber.
The key component that its positor head of this utility model is this apparatus; The front side of positor head and positor connecting rod are 120 °, and it is that arc is flat-shaped blunt nosed, and purpose is that the form of positor is consistent with the form of spinal cord; The convenient entering in the canalis spinalis made the blunt nosed Spinal Cord that prevents; Simultaneously head volume is compared moderately with canalis spinalis, and head is wide or blocked uply then be prone to occupy the canalis spinalis inner volume and cause spinal compression, and head is narrow then to be prone to be absorbed in the vertebral body of fracture; Arc dorsal part in a side has a plurality of point-like granules, makes dorsal part be matsurface, and frictional force increased and is difficult for sliding when purpose was that positor is pressed on the bone piece.The link of head and shaft portion is welded to connect with seamless, as long as mechanical strength well just can be accomplished.The shank of positor is flat awl cylindricality, makes with rubber wood timber, and there is backing metal in heart portion, prevents that shank from damaging because of impacting repeatedly.
This utility model advantage: 1, bone fragments in vertebral canal is suppressed, adopted to embed operation principle, the direct embedding of the bone piece of processus aboralis is advanced in the pathological changes vertebral body, can directly reset to the bone piece directly can enlarge canalis spinalis, need not to take out a position bone piece.
2, to detecting canalis spinalis once more behind the processus aboralis bone block reset, need not come return multiple operation, reduce neurovascular secondary tractive, be not easy to cause neural secondary damage.
3, less to the influence of canalis spinalis the place ahead venous plexus, be difficult for causing massive hemorrhage, less to the secondary injury that patient causes.
4, in canalis spinalis during reset operation, positor and bone fragments in vertebral canal are difficult for sliding, and other tissue of easy damaged is not simple to operate, safe and reliable.
Four, description of drawings
Accompanying drawing 1 is this utility model structure chart.
Accompanying drawing 2 is the cutaway view of this utility model.
Accompanying drawing 3 is an A partial enlarged drawing in the accompanying drawing 1.
Wherein:
1---positor head, 2---positor connecting rod, 3---plug, 4---positor shank, 5---sunk head rivet, 6---point-like granule
Five, the specific embodiment
Combining accompanying drawing to come this utility model is done further explain down.
With reference to accompanying drawing, this utility model bone fragments in vertebral canal positor, it comprises: positor head 1, positor connecting rod 2, positor shank 3; Positor head 1 is welded to connect with positor connecting rod 2; The front side of positor head 1 and positor connecting rod 2 are 120 °, and it is that arc is flat-shaped blunt nosed, have a plurality of point-like granules 6 to form the matsurface of dorsal part at head arc dorsal part; Positor shank 3 is flat awl cylindricality; Positor connecting rod 2 rear portions are provided with plug 3, and plug 3 usefulness screws are connected with positor connecting rod 2, have sunk head rivet 5 that positor connecting rod 2 is fixing in the positor shank 4; Positor shank 4 usefulness rubber wood timbers are made.
The method for using of this utility model: after to spinal canal decompression; Positor is vertical with spinal cord from the canalis spinalis of spinal cord outside entering spinal cord front side; Detect the particular location of bone fragments in vertebral canal and withstand the bone piece with head; Impact the positor shank gently with bone hammer the embedding of bone piece is pressed in the vertebral body of fracture, reach the purpose that sclerite is resetted; After resetting, earlier do not take out positor, can detect once more canalis spinalis sees whether bone resets soon fully with bone block reset device, whether spinal cord also have pressurized; If the canalis spinalis rear wall is polishing; Then take out positor,, can carry out secondary to the bone piece and suppress and reset if the bone piece not exclusively resets.The positor role is: 1, bone fragments in vertebral canal is suppressed, the bone piece is directly resetted directly can enlarge canalis spinalis.2, can carry out detecting in the canalis spinalis.Can reach save time, laborsaving, safe, purpose easily.
