Abstract
The invention relates to an acetabulum instrument, which is especially used for reduction and fixation in acetabulum fracture operation, and is a multi-type acetabulum instrument that comprises a trapezoidal arch body, a nail fixing hole and a T arm which are respectively used for fixing an anterior wall, an inner wall, an acetabulum top, a posterior wall and an inferior wall. Because the nail fixing hole of the trapezoidal arch body on the acetabulum instrument is designed into a tangential hole to lead the fixation of a bolt not to be perpendicular with an acetabulum fossa, an internal fixation operation can effectively avoid complications caused by acetabulum cartilage surface injury, thereby satisfying accurate reduction and fixation safety requirements of a biomechanics internal-fixation principle; in addition, the structure is simple, the installation is convenient, and the multiple types can be freely selected according to the operation needs.
Description
The invention belongs to medical category, exactly is that a cover is specifically designed to the implants that fracture of acetabulum resets, and its name is called acetabulum device.
In existing clinical fracture of acetabulum internal fixation technology, use flat reconstruction plate at present and implement internal fixation, existing serious disadvantage be the fixing acetabular bone cartilago parietalis damage complication that very easily causes in the art.Because acetabular fossa is a hemispherical, the mortar wall is weak and irregular again, begins to be inwardly back progressive additive of wedge shape from antelabium; When flat steel plate fixedly the time its plate hole vertical, it is inevitable perpendicular to acetabular fossa to put the nail direction, holing and putting the maximum risk of nail is the damage of mortar wall penetrance; In case penetrate; Not only caused the cartilago acetabularis damage even also can cause the damage of femoral head cartilage surface, will increase the wearing and tearing of hip joint greatly, quickened regression and increase the weight of the morbidity of traumatic arthritis.Yet also do not have specialized application to reset at present and can guarantee the implants that the acetabular bone joint is avoided damaging in fracture of acetabulum.So clinical expectation addresses this problem.
The internal fixation that the objective of the invention is to prevent to perform the operation causes cartilago acetabularis surface damage complication, for the clinical cover acetabulum device that provides comes the special for treating fracture of acetabulum.The acetabulum device that is designed can realize that the fracture of acetabulum anatomical reduction can guarantee that again hip joint avoids damaging again.Not only meet the biomechanics internal fixation principle fixedly safe requirement that resets accurately, and simple in structure, easy for installation, many types ofly can make things convenient for selection according to operation needs.
The present invention adopts following measure to realize to achieve these goals: acetabulum device is by trapezoidal donor, " T " arm and follow closely the hole admittedly and constitute multiple type acetabulum device, is respectively applied for fixing of antetheca, inwall, mortar top, rear wall, lower wall.Trapezoidal donor and the main body of following closely hole formation acetabulum device admittedly." T " arm is extended by the side of trapezoidal donor; Constitute single " T " arm acetabulum device, extend two " T " arm acetabulum devices that are of two " T " arms by stretch out " T " arm of trapezoidal donor; What extend " T " arm more than two be many " T " arm acetabulum device, and by trapezoidal donor with follow closely the hole admittedly to form what do not have " T " arm formation be no arm acetabulum device.Be shaped on solid nail hole respectively on trapezoidal donor and " T " arm.1-4 fixing hole arranged respectively on " T " arm.Polytype is selected demand with the internal fixation that satisfies complex acetabular property fracture.
The present invention also adopts following measure to realize to achieve these goals: above-described trapezoidal donor, its transverse section are trapezoidal or rectangular triangle, upward are the plane, are the inclined-plane down, and right-angle side is that the thickness of trapezoidal donor is webbing.The major axis of trapezoidal donor vertically be inside arc bending and arch upwards, forms inside and outside two arc edge and two arch faces up and down, and the form of its inner arc edge and following arch face and the dissection outer wall of acetabular bone match basically.Solid nail hole on the trapezoidal donor is perpendicular to last arch face, and the solid nail Kong Ze of following arch face is the inclined-plane.Admittedly follow closely the hole when its inclined-plane and acetabular bone outer wall stick and acetabular fossa is the tangent line level, guarantee that the installation of screw can not get into acetabular fossa.Two edges of following closely admittedly between the hole of trapezoidal donor are " U " v notch v, are beneficial to bending adjustment in the art.
The present invention can also adopt following measure to realize to achieve these goals: the major axis of above-described trapezoidal donor is the arc donor, and an end is and reverses body, is used for fixing the mortar top, and the other end is the bow bending, is used for fixing ischium, the center fixed rear wall.The rear pillar that is used for by trapezoidal donor and " T " arm constitute is strengthened fixing.
The present invention can also adopt following measure to realize to achieve these goals: the above follows closely the hole admittedly, and hole shape has circle, the orthogonal counter sink of circle and lock hole multiform, and lock hole is a screwed hole, is used for the lockplate nail.
Below in conjunction with accompanying drawing and embodiment the present invention is done further explanation.
Fig. 1 is " T " more than one of the present invention arm acetabulum device example structure sketch map.Trapezoidal donor (1) semicircular in shape.By trapezoidal donor and a plurality of " T " arm (2,5,11,14) with follow closely hole shape admittedly and be integral.There is 1 and 3 on " T " arm and follows closely hole (4,12) admittedly.Solid nail hole (3,8,7) on the trapezoidal donor is uniformly distributed with continuously, and two edges of following closely admittedly between the hole are " U " v notch v (6).
Fig. 2 is the cross-section cross-sectional view of A-A of trapezoidal donor with " T " arm coalition of acetabulum device of the present invention.One side of trapezoidal donor is featheredge (9), and another side is webbing (13), and plane in the formation (10) are vertical with the webbing of trapezoidal donor, and " T " arm is extended in parallel by the side-lower of the lower inclined plane (18) of trapezoidal donor and trapezoidal donor webbing and forms (11).
