Abstract

The utility model relates to a high-neck hollow artificial hip joint handle, which comprises a body (10) which is provided with a supporting body (11) and a cylinder body (12), wherein, through being matched with a femoral bone shape, the supporting body (11) is in a curved shape and is in a gradually inward condensation shape from one end to the other end; the internal part of the cylinder body (12) is in a hollow shape; one end of the cylinder body is in a sealing shape, and the other end in a gradually outward expanded and open shape. The surface of the cylinder body (12) is provided with more than one opening (121) and outwardly protruding hook bodies (122). Accordingly, during the treating period, medical fillers or other fillers are directly poured into the cylinder body from the opening of the cylinder body and can flow into the femoral bone body from the opening on the cylinder body. The utility model not only can be convenient for treatment of doctors, but also can strengthen combination of the body and a femoral bone body, and healing of the femoral bone can be accelerated. Since the surface of the cylinder body is respectively provided with the outwards convex hook bodies, by means of frictional force among the hook bodies on the cylinder body and the internal walls of the femoral bone body, the supporting body can not be generated with loose and disengaging states.

Description

高颈中空人工髋关节柄 High-neck hollow handle artificial hip joint

技术领域 FIELD

本实用新型涉及一种人工髋关节柄,尤其涉及一种高颈中空的人工髋关节柄。 The present invention relates to a prosthetic hip stem, in particular, it relates to a high-neck hollow artificial hip stem.

为了改进上述的缺点,随之出现了一种髋关节假体,请参照图1所示,该假体上设有一略呈弯曲状的柱状体,该柱状体顶端上设有一凸出的颈轴承,该颈轴承上螺合一帽体,该装置构造在使用时,需将股骨颈切除,才能使柱状体在插入股骨体中,且因该柱状体表面呈平滑状,故,该柱状体在插入股骨体中时,无法附着在股骨体壁面上,进而易从其中滑出,再者,因该柱状体为实心体,因此在治疗期间,股骨体中无法灌入任何治疗的药物或帮助股骨体与柱状体结合的注入物,这样将使其愈合缓慢。 In order to improve the above disadvantages, it appears a hip prosthesis, refer to FIG. 1, is provided with a slightly curved shape of the columnar body prosthesis, provided with a projecting journal bearing on the top of the columnar body the spiro-one upper neck bearing cap, the device is configured in use, the need to cut the femoral neck, in order to make the columnar body is inserted into the body of the femur, and because of the cylindrical body leaving it smooth shape, so that the columnar body when inserted into the body of the femur, the femur can not be attached to the wall surface, and further wherein from slipping out easily. Further, because the columnar body is a solid body, and therefore during the treatment, the body can not be poured into the femoral any medical treatment or help femur the columnar body and binding of implant, so that it will heal slowly.

为了解决上述技术问题,本实用新型采用了下述技术方案,提供一种一种高颈中空人工髋关节柄,其包括一设有支撑体及筒体的本体,所述的支撑体配合股骨形状而呈弧曲状,且呈由一端向另一端逐渐向内缩合状,所述的筒体设于支撑体旁并与之配合且内呈中空状,所述筒体的一端呈封闭状,而另一端则呈逐渐向外扩张的开放状,该筒体表面上设有一个以上的孔洞及向外突出的钩体;所述的支撑体一端设有一人工股骨头。 To solve the above technical problem, the present invention adopts the following technical scheme, a high-necked to provide a hollow prosthetic hip stem comprising a support and provided with a cylindrical body, the support of the mating femoral shape arcuate shape and form, and was gradually inwardly from one end toward the other end of the condensation-shaped, said cylindrical body at the side and the support and mates with the hollow shape, one end of the cylinder was closed shape, and the other end open like shape gradually expands outward, and has one or more outwardly projecting hook hole on the surface of the cylinder; end of the supporting body is provided with an artificial femoral head.

这样在治疗期间可将药物或其它的填充物,直接由筒体的开口灌入筒体中,并由筒体上的孔洞流入股骨体中,不但可方便医生的治疗,且可以加强本体与股骨体的结合,并加速股骨的愈合;由于筒体表面分别设有向外凸出的钩体,因此该支撑体可凭借筒体上的钩体与股骨体内壁间的摩擦力,而不会有松动脱离的情形发生;由于支撑体顶端上锁合有人工股骨头,可使髋关节活动自如。 Thus during treatment can be a drug or other fillers, is directly poured into the barrel by the opening cylinder by the inflow holes in the cylinder body, femur, not only convenient medical treatment, and can enhance body and femur binding body, femur and accelerate healing; since each surface of the cylinder is provided with outwardly projecting hook, so that the support hook by virtue of the friction between the walls and the body of the femur on the barrel, without the loose from the situation occurs; as a support to the top locking engagement with a femoral head, hip joint can move freely.

另,该本体10在支撑体11旁设有与之配合且内呈中空状的筒体12(如图4所示),于本实施例中为锥形体,该筒体12可与支撑体11一体成型,或通过接合方式组合而成,该筒体12与支撑体11向内缩体端呈封闭状,而另一端则呈逐渐向外扩张的开放状,且该筒体12表面上设有一个以上的孔洞121及向外突出的钩体122。 Also, the body 10 is provided with a support 11 next to the fit and the shape of a hollow cylinder 12 (FIG. 4), in the present embodiment is a cone, the cylindrical body 12 and the support member 11 may be integrally formed, or through a combination of engagement, the end member 11 inward contraction of the cylinder 12 and the support form a closed shape, and the other end open like shape gradually expands outward, and the upper surface of the cylindrical body 12 is provided with one or more holes 121 and the hook 122 protruding outward.

再者,该支撑体11在载面积较大的一端上接设有一固定件111,在本实施例中为一螺杆(本领域内的技术人员,也可以用其它元件取代),该固定件111上套合有一人工股骨头20。 Further, the support member 11 on the larger end area of ​​the carrier is provided with a fixed contact member 111, (those skilled in the art, may be substituted with other elements) in this embodiment is a screw, the fixing member 111 fit on a femoral head 20.

使用时,请参照图5、6、7、8所示:先将受损的股骨头切除,再将股骨颈作适当处理后,将本体10插入股骨体30中,使体体10上的支撑体11及筒体12深入股骨体30中,如此一来,不但可较现有结构所需切除的部分少,且在治疗期间更可将药物或其它的填充物,直接由筒体12呈开放状的一端灌入筒体中,并通过筒体12上的孔洞121流入股骨体30中,如此,不但可方便医生的治疗,且可以加强本体10与股骨体30的结合,并加速股骨的愈合。 In use, referring to FIG 5,6,7,8 shown: first damaged femoral resection, and then the neck for proper treatment, the body 10 is inserted into the femoral body 30, the supporting member 10 on the body 30 in this way, not only compared with the conventional structure of the desired cut 11 and the cylindrical portion of a small depth of the femoral member 12, and may be more drugs or other filler during treatment, was directly by the cylindrical body 12 open poured into the end of the barrel-shaped, and into the femoral body 30 through the holes 121 on the cylinder 12, thus, not only convenient medical treatment, and may strengthen the binding body 10 and the body 30 of the femur, the femur and accelerate healing . 另,其筒体12的孔洞121,可使股骨及股骨颈新长出的血管及痂疤可穿过其中,而覆盖在本体10上,进而使本体10可与股骨结合成一体,再者,该支撑体11上锁合有人工股骨头20,使髋关节活动自如,此外,该筒体12表面分别设有向外凸出之钩体122,如此一来,该支撑体11可通过筒体12上的钩体122与股骨体30内壁间的摩擦力,而不会有松动脱离的情形发生。 Also, the cylindrical body which hole is 12112, and the femoral neck can grow new blood vessels and scar can scab therethrough, and overlaid on the main body 10, and thus the main body 10 may be integrally combined with the femur, furthermore, the support member 11 has a locking engagement femoral head 20, the hip joint freedom of movement, in addition, the surface 12 of the tubular body are provided with outwardly projecting hook 122, Thus, the support member 11 may be through the barrel hook 122 on the friction between the femur 12 and the inner wall 30, without the departing from loosening situation occurs.

综上所述,本实用新型可改进原有技术的各种缺点,在使用上能增进功效。 In summary, the shortcomings of the present invention can improve the existing technology in use can enhance the effect.
