Abstract
The utility model discloses a pessulus bridge steel plate which comprises a strip steel plate, both ends of which are provided with plural through holes for connection. The utility model is characterized in that the pessulus bridge steel plate is also comprises hexagon socket head cap screws corresponding to the numbers of the through holes connected to the steel plate, bridge pads and a pad between the screw nut inner side of the screw outer part and the surface of the broken bone being set. The hexagon socket head cap screws pass through the corresponding through holes connected to the steel plate and the broken bone being set; the bridge pads are through screws connected to the screw bolt between the inner side of the steel plate and the surface of the broken bone being set; the steel plate bridges over the bone fracture point, which makes up the bridge. The pessulus bridge steel plate of the structure is provided with bridge pads on the both sides of the bone fracture point. The steel plate and the surface of bone are contactless. The steel plate interconnects the broken bones in the way of bridge through screw bolts, which avoids stripping off the periost and flab around the bone fracture point in large area; the steel plate does not compress the cortical bone directly, which enables the bone fracture to remain blood moving stable, and is favourable for the rebuilding of the bone fracture point blood moving and the knitting of the fractured bone. What's more, the utility model has simple structure, is reliable for fixing the fractured bone and applies to the bone-knitting and treatment of various bone fractures.
Description
Technical field
This utility model relates to a kind of surgical medical equipment, in particular for the blade plate of synthetism.
Background technology
The steel plate of internal fixation treatment of being widely used at present fracturing has general steel plate, compression steel plate, tubulose steel plate, reconstruction plate, limited contact steel plate, corrugated sheet steel, some contact steel plate.This class steel plate is rectangle mostly, and certain thickness is arranged, and is useful on the circular or oval eyelet that screw connects on the plate, joins screw and uses together.Be applied to fracture when docking fixedly, generally want the strip off periosteum, blade plate could be installed in the position that exposes fracture end and place steel plate.Earlier after the fracture para-position, place bone to be close to cortical bone outward the monoblock steel plate, then at the eyelet position of steel plate bore bone hole, be screwed into screw again along the bone duct two ends of steel plate and fracture are connected and installed together, steel plate is close to bone, to provide fixing.
When this type steel plate is used to fracture internal fixation,, remaining blood fortune of fracture end and stability are all gone to pot, be unfavorable for the healing of fracturing owing to want strip off fracture end periosteum and soft tissue on every side.In addition, steel plate is close to cortical bone and is fixed, because the direct compressing of steel plate, repressive osteanabrosis might appear in the surface of bone that contacts with steel plate; Phenomenon obviously takes place to fracture once more after also might causing osteoporosis and taking out steel plate in the effect of blocking of this fixation pressure.
Summary of the invention
The purpose of this utility model provides a kind of simple and practical, and soft tissue injury is little, does not directly oppress cortical bone, places without the strip off periosteum, the remaining blood fortune of fracture end is disturbed lacked, and can effectively fix the bolt bone connected steel plate of fracture.
This utility model comprises the steel plate of a strip and block, is provided with the open-work that several are used to connect at the two ends of steel plate, it is characterized in that also comprising:
Connect the corresponding hexagon socket head cap screw of open-work quantity with described steel plate, this bolt passes corresponding connection open-work and institute's synthetism of steel plate;
The bridge pad of thread connection on bolt between described steel plate inboard and the institute's synthetism face, steel plate stride across a fracture mouthful formation bridge joint;
Be located at the pad between bolt outer end nut inboard and the institute's synthetism face.
The screw rod of described bolt is a full flight screw.
Described bridge pad is provided with female thread.
Two sides, the outside and two ends are circular arc in the described steel plate.
The bolt bone connected steel plate of above structure is provided with the bridge pad between the steel plate of both sides of fracture mouthful and surface of bone, steel plate and surface of bone are discontiguous, to roll over the bone two ends by bolt in the mode of bridge joint interconnects, avoided large tracts of land strip off fracture end periosteum and soft tissue on every side, steel plate is not directly oppressed cortical bone, make the remaining blood fortune of fracture stable, help the reconstruction and the folding symphysis of fracture end blood fortune.And, of the present utility model simple in structure, fixed, can effectively prevent the loose phenomenon of following closely, moving back nail, the inside and outside two sides of steel plate and two ends are made circular-arc, can alleviate the tension force and the frictional force of the outer skin and flesh structure of steel plate and bone, reduce patient's misery.
Description of drawings
Shown in Figure 1, be that structure master of the present utility model looks sketch map.
Shown in Figure 2, be that sketch map is looked on the left side of Fig. 1.
Shown in Figure 3, be the schematic top plan view of Fig. 2 light plate 1.
The specific embodiment
Looked with the left side of Fig. 2 by the structure master of Fig. 1 and to look in the sketch map as can be known, this utility model is made up of a bar steel plate 1, four bolts 3 and nut thereof 8, four bridge pads 5 and four nut shims 7, upper end 6 and lower end 9 corresponding fixedlying connected that will the folding bone.So Fig. 1 and Fig. 2 also are user mode structural representations of the present utility model.Wherein, the corresponding position at steel plate 1 two ends respectively is provided with two open-works 2 that heavy hole is arranged, and respectively is installed with a hexagon socket head cap screw 3, also passes the required corresponding position that connects folding bone upper and lower side 6 and 9 of refuting respectively.The hex bolts head sinks in the hole 2, and on the screw rod of bolt 3 between the inboard of steel plate 1 and the respective face surface of bone, thread connection has bridge pad 5, after screw rod passes bone, is provided with pad 7 between the inboard of another surface of bone and nut 8.Like this, bridge pad 5 is erected steel plate 1 two ends, steel plate 1 as bridge be connected across the fracture mouthful two ends, the medial surface of steel plate 1 directly is not pressed on the corresponding surface of bone, the outer end of bolt 3 firmly tightens by pad 7 and nut 8 on another surface of bone, will roll over the bone two ends and fix.Bolt Connection can not produce the phenomenon that the pine nail moves back nail than the good stability of screw attachment.The bridge joint mode helps the surface of bone soft tissue and adheres to and the supply of blood fortune, can accelerate to roll over knitting.By seeing among Fig. 1, Fig. 2 and Fig. 3, the two ends 4 of steel plate 1 is a circular arc, and the junction on lateral surface 10 and medial surface 11 and two sides also all is a circular arc, can alleviate steel plate 1 and the tension force and the frictional force that cover endothelial tissue on it, reduces patient's misery.
