股骨支撑装置 Femur support means

技术领域 FIELD

[0001] 本发明涉及骨科医疗器材,尤其涉及一种可装设于股骨中且搭配髋白杯使用以构成人工髋关节的股骨支撑装置。 [0001] The present invention relates to orthopedic medical devices, particularly to a femur and mounted in white cups with hip support means used to constitute the femoral hip joint.

背景技术 Background technique

[0002] 请参照图1,其为一种现有的股骨支撑装置9,该现有的股骨支撑装置9包括一座体91、一支撑柄92及一斜柱93,该支撑柄92具有一骨柄端921及一关节端,该斜柱93由一端一体连接该支撑柄92的关节端922;组装时,该支撑柄92的骨柄端921贯穿该座体91,且该座体91卡掣结合在较邻近该关节端922处,以稳固定位该支撑柄92。 [0002] Referring to FIG 1, which is a conventional femoral support means 9, the conventional support means 9 comprises a femoral member 91, a support handle 92 and a diagonal column 93, the support handle 92 having a shank bone end 921 and a joint end of the inclined post 93 from one end integrally connected to the support handle articular 92292; and when assembled, a stem end of the support lever 92 is 921 extends through the base body 91 and the seat 91 engaging incorporated the nearer the end of the joint 922, to secure the support handle 92 is positioned.

[0003]欲将该现有的股骨支撑装置9植入人体时,需先切开包覆于股骨F处的肌肉与韧带,并锯除股骨颈及股骨头,再对股骨F中的松质骨(cancellous bone)凿孔以植入该现有的股骨支撑装置9。 [0003] For conventional femur when implanted in the body the support means 9, to be coated on the first cut of the femur F and the muscle ligaments, and other saws femoral neck and femoral head cancellous then the femur F bone (cancellous bone) punctured prior to implanting the femoral support device 9. 该现有的股骨支撑装置9植入患者的股骨F后,该斜柱93会呈倾斜地凸出在患者的股骨F外,用以取代股骨颈,供一髋臼组件(图未绘示)组装在该斜柱93的自由端。 After the conventional femoral support device implanted in a patient's femur F. 9, the column 93 will be inclined obliquely protrude outside the patient's femur F., Substituted for the neck, for an acetabular component (not shown) in the free end of the ramp assembly 93 of the column.

[0004] 但该现有的股骨支撑装置9仅由单一个斜柱93支撑身体垂直应力及股骨转子斜向扭力,难以有效地分散受力,使得该现有的股骨支撑装置9易于使用一段时间后发生失效的问题。 [0004] However, the conventional femoral support device 9 a swash only a single column to support the body 93 and the vertical stress oblique intertrochanteric torque, it is difficult to effectively disperse the force, so that the conventional femoral support device 9 is easy to use for some time after the failure of the problem to occur.

[0005] 另外,该斜柱93—体连接该支撑柄92,因而无法依据患者的骨骼形态任意改变该支撑柄92或该斜柱93的长度,或是调整该斜柱93与该支撑柄92之间的倾斜角度等,故该现有的股骨支撑装置9需制备多种规格以供选用,对于医院的物料管理十分不便,也易造成厂商囤货的压力。 [0005] Further, the swash body is connected to the column support handle 93- 92, and therefore can not arbitrarily change the length of the shank 92 or the support post 93 of the helical form of the patient's bone based, or adjusting the diagonal column 93 and the support handle 92 the angle of inclination, etc., so the conventional femoral support means 9 need for preparing a plurality of selection specifications, materials for hospital management is very inconvenient, manufacturers also cause pressure stockpile. 并且,该现有的股骨支撑装置9的每一个规格品即包括完整的支撑柄92与斜柱93,其用料量大,成本高,且相当占用储放空间。 Further, the conventional support device femur 9 each comprising a complete specification product i.e. support handle 92 and the swash column 93, which was a large quantity, the high cost and take up considerable storage space.

[0006]类似于上述的股骨支撑装置9的一实施例已公开于中国台湾公告第1312677号《人工股骨结构》专利案当中,其他如中国台湾公告第M394805号《股骨假体》、第M389530号《高抗压性内填充抗生素骨水泥股骨支撑装置》及第1305722号《具有多孔性组织的人工骨头》 等专利案也具有类似的结构,故同样具有上述缺点。 [0006] Similar to the above embodiment of a femoral support device embodiment disclosed in China Taiwan Publication No. 1312677 "artificial femoral Structure" which patent case, others such as China Taiwan Publication No. M394805 "femoral prosthesis" 9, No. M389530 "a high compressive strength cement to fill femoral antibiotics support means" and No. 1,305,722, "a porous artificial bone tissue" and patent case also has a similar structure, it also has the aforementioned disadvantages.

[0007] 有鉴于此,现有的股骨支撑装置确实仍有加以改善的必要。 [0007] In view of this, the conventional apparatus does femur support still need to be improved.
