Abstract
The invention relates to a modularized manual acetabulum cup which is arranged in an acetabular fossa and used for connecting an artificial thighbone bulb. The modularized manual acetabulum cup comprises a bowl-shaped semicircular acetabulum cup and an extending shell, wherein the acetabulum cup is provided with an outer circumferential surface contacting with the acetabular fossa and an inner circumferential surface connected with the artificial thighbone bulb, and one side edge of the outer circumferential surface protrudes out of the acetabular fossa and is provided with a first connecting part; the extending shell is provided with a second connecting part jointed with the first connecting part; the extending shell is provided with an abutting surface attached to the bone wall near the acetabular fossa, a jointing surface connected to a plane formed by an opening of the acetabulum cup and an outer plane connected with the jointing surface and provided with an angle relative to the jointing surface; and the extending shell is provided with a plurality of positioning holes penetrating through the abutting surface and the outer plane. In the invention, different sizes of extending members are combined to be attached to various acetabulum cups with acetabular fossa shapes, therefore, different sizes of extending shells are produced to meet the requirements on various patients by changing the angle of the jointing surface relative to the abutting surface.
Description
Technical field
The present invention relates to a kind of modularized manual acetabulum cup, particularly relate to and a kind ofly utilize the combined member of different size and satisfied the modularized manual acetabulum cup of various acetabular bone bone shapes.
Background technology
Hip joint is for having carried the important joint of human body weight over half; yet hip joint also easily with advancing age, various situations such as wound or inflammation and form hip joint disease; its chief reason is because heavy wear of femoral head cartilage or femoral head distortion; cause the hip joint can't normal activity; further causing sufferer influences the normal limbs action of sufferer because pain is uncomfortable, and severe patient also might be lost Motor ability.
The modal therapeutic modality of above-mentioned hip joint pathological changes then is to impose total man worker's hip replacement, rebuild the normal function of hip joint, and the member of the employed total man worker's hip joint of this kind operation can be divided into artificial femur handle, artificial femur bulb and manual acetabulum cup haply, wherein the locate mode of manual acetabulum cup, angle, fastness are to influence one of the most key factor of sufferer hip stability after operation.
Before the existing known installation manual acetabulum cup, sufferer originally must be out of shape or the acetabular bone place of pathological changes carries out skiving, grind semicircle depression to form the location of again manual acetabulum cup being packed into behind the acetabular fossa, and relevant manual acetabulum cup technology such as United States Patent (USP) the 4th, 596, No. 580 " hip cotyle cup " (HipJoint Socket) and the 4th, 955, shown in No. 325 " the acetabular bone system that clearance space is consolidated " (Acetabular Cup Component Cement Spacer System), pattern for the existing semi-circular manual acetabulum cup of known standard, and the situation of suitable most of sufferers, only need to grind the acetabular fossa that to install this manual acetabulum cup at primary acetabulum cup place, last utilize various fixing or screw lock means this manual acetabulum cup to be installed in the acetabular fossa that is harmonious again, the structure of above-mentioned this kind manual acetabulum cup can have been dealt with the demand of most of sufferers, because most of sufferers can grind acetabular fossa at primary acetabulum cup place easily, and the plane that opening constitutes of acetabular fossa can with respect to the horizontal plane form about miter angle, make when manual acetabulum cup places in this acetabular fossa, the plane that opening constituted of this manual acetabulum cup also can with respect to the horizontal plane reach about miter angle, make us when worker's femur bulb is harmonious coupling with this manual acetabulum cup enough vertical lifting surface areas being arranged, relatively near limbs script range of activity, also be relatively to be not easy to cause the dislocation of femur bulb simultaneously, the orientation angle of dislocation.
Yet aforementioned content is only for installing the ideal state of this manual acetabulum cup, the femoral bone cavitas medullaris size and shape that can find human body when practical operation can be because ethnic group, age, sex, or the difference of disease and difference to some extent, the acetabular fossa that makes sufferer dig out at primary acetabulum cup place mill may present shallow, distortion, cause the existing known semicircular manual acetabulum cup of standard that is to be difficult to be harmonious and to influence its stability in the acetabular fossa that is ground, therefore develop and the design of modularity mortar cup, as United States Patent (USP) the 6th, 416, shown in No. 553 " method and apparatus of modularized manual acetabulum " (Method And Apparatus For ProvidingModular Acetabular Prosthesis), its main body still is the semicircular manual acetabulum cup of a standard, but the place different with existing known techniques is this manual acetabulum cup and has various assist location member, make this manual acetabulum cup be able to be positioned by the assist location member acetabular fossa of different shape; And for example United States Patent (USP) the 5th, 326, shown in No. 368 " method of acetabular bone " (Method AcetabularCup), this kind manual acetabulum cup has a main semicircular main mortar cup, and has difform spherical shell in addition, for example fan-shaped spherical shell, oval spherical shell are combined into complete manual acetabulum cup by this difform spherical shell and this main mortar cup, and can be harmonious in the acetabular fossa shape of oval calotte or other irregular curved surfaces.
Utilize above-mentioned existing known techniques, can make us worker's acetabular cup is harmonious in the acetabular fossa that grinds in different sufferer, yet insufficient place is, though under technology now, manual acetabulum cup can close in various acetabular fossa, but consider primary acetabular bone distortion, odd-shaped sufferer, the plane that opening the constituted angle with respect to the horizontal plane of its acetabular fossa that grinds may be excessive, even if make manual acetabulum cup energy strong fix in this acetabular fossa, the plane that opening the constituted angle with respect to the horizontal plane of this manual acetabulum cup is also excessive, and cause vertical stressed contact area deficiency with the artificial femur bulb, cause easy dislocation, dislocation, if adjusted the angle of this manual acetabulum cup based on existing known techniques, the plane that opening the constituted angle with respect to the horizontal plane of making us worker's acetabular cup is near miter angle, then must cause the manual acetabulum cup upper limb to protrude from outside this acetabular fossa, and can't keep the stability that manual acetabulum cup fixedly positioning.
This shows that above-mentioned existingization manual acetabulum cup obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of modularized manual acetabulum cup of new structure, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
Summary of the invention
Main purpose of the present invention is, remedy the defective that existing known manual acetabulum cup exists, and provide a kind of modularized manual acetabulum cup of new structure, technical problem to be solved is to make it be able to difference along with sufferer acetabular cup shape, and the manual acetabulum cup of different orientation angles is provided, be very suitable for practicality.
