如图5所示，第一本体24的上端设置有第一通孔241，第二本体25的上端设置有第二通孔251，髋关节假体还包括紧固件32，第一本体24和第二本体25通过紧固件32穿设于第一通孔241和第二通孔251连接。采用紧固件32连接第一本体24和第二本体25，具有便于装配的优点。As shown in FIG. 5 , the upper end of thefirst body 24 is provided with a first throughhole 241 , the upper end of thesecond body 25 is provided with a second throughhole 251 , the hip joint prosthesis further includes afastener 32 , thefirst body 24 and the Thesecond body 25 is connected through the first throughhole 241 and the second throughhole 251 through thefastener 32 . Using thefastener 32 to connect thefirst body 24 and thesecond body 25 has the advantage of being easy to assemble.

在本实施例中，第一本体24的靠近第二本体25的一侧设置有第一台阶242，第二本体25具有对应第一台阶242设置的第二台阶，第一台阶242和第二台阶均沿假体本体20的上下方向延伸，第一台阶242和第二台阶插接配合。采用上述结构，便于利用第一台阶242和第二台阶对第一本体24和第二本体25进行限位，使第一本体24和第二本体25不会产生错位。In this embodiment, afirst step 242 is provided on the side of thefirst body 24 close to thesecond body 25 , thesecond body 25 has a second step corresponding to thefirst step 242 , thefirst step 242 and the second step Both extend along the up-down direction of theprosthesis body 20 , and thefirst step 242 and the second step are plug-fitted. With the above structure, it is convenient to use thefirst step 242 and the second step to limit the position of thefirst body 24 and thesecond body 25, so that thefirst body 24 and thesecond body 25 will not be displaced.

需要说明的是，第一台阶242和第二台阶插接配合，指的是第一台阶242的水平台阶面和第二台阶的水平台阶面相抵接，第一台阶242的竖直台阶面和第二台阶的竖直台阶面相抵接。It should be noted that the plug-fit of thefirst step 242 and the second step means that the horizontal step surface of thefirst step 242 is in contact with the horizontal step surface of the second step, and the vertical step surface of thefirst step 242 is in contact with the horizontal step surface of the second step. The vertical step surfaces of the two steps abut against each other.

As used herein, unless the context clearly dictates otherwise, the singular is intended to include the plural as well, furthermore, it is to be understood that when the terms "comprising" and/or "including" are used in this specification, it indicates that There are features, steps, operations, devices, components and/or combinations thereof.

除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本发明的范围。同时，应当明白，为了便于描述，附图中所示出的各个部分的尺寸并不是按照实际的比例关系绘制的。对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为说明书的一部分。在这里示出和讨论的所有示例中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它示例可以具有不同的值。应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。The relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the invention unless specifically stated otherwise. Meanwhile, it should be understood that, for the convenience of description, the dimensions of various parts shown in the accompanying drawings are not drawn in an actual proportional relationship. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and apparatus should be considered part of the specification. In all examples shown and discussed herein, any specific value should be construed as illustrative only and not as limiting. Accordingly, other examples of exemplary embodiments may have different values. It should be noted that like numerals and letters refer to like items in the following figures, so once an item is defined in one figure, it does not require further discussion in subsequent figures.

在本发明的描述中，需要理解的是，方位词如“前、后、上、下、左、右”、“横向、竖向、垂直、水平”和“顶、底”等所指示的方位或位置关系通常是基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，在未作相反说明的情况下，这些方位词并不指示和暗示所指的装置或元件必须具有特定的方位或者以特定的方位构造和操作，因此不能理解为对本发明保护范围的限制；方位词“内、外”是指相对于各部件本身的轮廓的内外。In the description of the present invention, it should be understood that the orientations indicated by orientation words such as "front, rear, top, bottom, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" etc. Or the positional relationship is usually based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and these orientation words do not indicate or imply the indicated device or element unless otherwise stated. It must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be construed as a limitation on the protection scope of the present invention; the orientation words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。For ease of description, spatially relative terms, such as "on", "over", "on the surface", "above", etc., may be used herein to describe what is shown in the figures. The spatial positional relationship of one device or feature shown to other devices or features. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or features would then be oriented "below" or "over" the other devices or features under other devices or constructions". Thus, the exemplary term "above" can encompass both an orientation of "above" and "below." The device may also be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptions used herein interpreted accordingly.

此外，需要说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本发明保护范围的限制。In addition, it should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood to limit the scope of protection of the present invention.
