Translated fromChinese技术领域technical field
本实用新型涉及骨科医疗器械技术领域，特别涉及一种全膝关节置换术用的髁间截骨导向器和骨科手术器械。The utility model relates to the technical field of orthopedic medical instruments, in particular to an intercondylar osteotomy guide and orthopedic surgical instruments for total knee joint replacement.
背景技术Background technique
股骨髁假体置换是全膝关节置换术中极为重要的一部分。医生在选择患者所对应股骨头大小的假体时，会用相对应大小的截骨板进行截骨。在处理股骨远端截骨时，髁间截骨是极为重要的一个环节，在髁间截骨时，医生采用髁间截骨板进行截骨的操作。目前在使用髁间截骨板时，先安装好髁间截骨板，摆锯会沿着髁间截骨板中间缺口的边缘向下截骨。但是在使用摆锯时，由于髁间截骨板没有完全限制摆锯的方向，在截骨过程中所产生的震动会导致摆锯截骨产生偏差，造成截骨不精准，导致截骨量不稳定，严重影响了手术效果和后期假体的稳定性，从而导致假体松动脱落的风险。Femoral condyle replacement is an extremely important part of total knee arthroplasty. When the doctor selects the prosthesis of the corresponding femoral head size of the patient, the osteotomy plate of the corresponding size will be used for osteotomy. Intercondylar osteotomy is an extremely important link in the treatment of distal femur osteotomy. During intercondylar osteotomy, doctors use the intercondylar osteotomy plate to perform the osteotomy operation. At present, when the intercondylar osteotomy plate is used, the intercondylar osteotomy plate is installed first, and the oscillating saw will cut the bone downward along the edge of the gap in the middle of the intercondylar osteotomy plate. However, when the oscillating saw is used, since the intercondylar osteotomy plate does not completely limit the direction of the oscillating saw, the vibration generated during the osteotomy will cause deviation of the oscillating saw osteotomy, resulting in inaccurate osteotomy and insufficient osteotomy. Stability, which seriously affects the surgical effect and the stability of the prosthesis in the later stage, resulting in the risk of the prosthesis loosening and falling off.
因此，亟需一种能够避免截骨工具在截骨过程中产生偏差的髁间截骨导向器和骨科手术器械。Therefore, there is an urgent need for an intercondylar osteotomy guide and an orthopaedic surgical instrument that can avoid the deviation of the osteotomy tool during the osteotomy process.

Next, the present invention is described in detail by using schematic diagrams, but these schematic diagrams are only for the convenience of illustrating the preferred embodiments of the present invention, and should not be regarded as a limitation of the present invention.
另外，以下说明内容的各个实施例分别具有一或多个技术特征，然此并不意味着使用本实用新型者必需同时实施任一实施例中的所有技术特征，或仅能分开实施不同实施例中的一部或全部技术特征。换句话说，在实施为可能的前提下，本领域技术人员可依据本实用新型的公开内容，并视设计规范或实际需求，选择性地实施任一实施例中部分或全部的技术特征，或者选择性地实施多个实施例中部分或全部的技术特征的组合，借此增加本实用新型实施时的弹性。如在本说明书中所使用的，单数形式“一”、“一个”以及“该”包括复数对象，除非内容另外明确指出外。In addition, each embodiment of the following description has one or more technical features, but this does not mean that the user of the present invention must implement all the technical features in any embodiment at the same time, or can only implement different embodiments separately. one or all of the technical features. In other words, under the premise of possible implementation, those skilled in the art can selectively implement some or all of the technical features in any embodiment according to the disclosure of the present invention and depending on design specifications or actual needs, or The combination of some or all of the technical features in the multiple embodiments is selectively implemented, thereby increasing the flexibility of the implementation of the present invention. As used in this specification, the singular forms "a," "an," and "the" include plural referents unless the content clearly dictates otherwise.
如在本说明书中所使用的，术语“或”通常是以包括“和/或”的含义而进行使用的，除非内容另外明确指出外。如在本说明书中所使用的，术语“若干”是指数量不确定的含义，除非内容另外明确指出外。如在本说明书中所使用的，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者至少两个该特征。本文中，“内侧面”指的是靠近截骨工具的一侧；“外侧面”指的是远离截骨工具的一侧。As used in this specification, the term "or" is generally employed in its sense including "and/or" unless the content clearly dictates otherwise. As used in this specification, the term "a number" refers to an indefinite quantity unless the content clearly dictates otherwise. As used in this specification, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implying the number of indicated technical features. Thus, features delimited with "first" and "second" may expressly or implicitly include one or at least two of such features. As used herein, "medial side" refers to the side closer to the osteotomy tool; "lateral side" refers to the side away from the osteotomy tool.
本实用新型的核心思路在于提供一种髁间截骨导向器，适配于髁间截骨板。该髁间截骨导向器包括锁紧结构和定位结构；所述定位结构用于可拆卸地设置在髁间截骨板上，并用于与髁间截骨板共同限定形成截骨导向槽；所述锁紧结构用于可拆卸地连接所述定位结构，以锁定所述定位结构和所述髁间截骨板。使用时，截骨工具穿过所述截骨导向槽进行截骨，并在截骨过程中，利用截骨导向槽限制截骨工具的方向，使截骨工具在截骨过程中不会因为震动产生偏差，确保截骨的稳定性和精准性，保证手术效果和后期假体的稳定性。此外，所述截骨工具包括但不限于摆锯。The core idea of the present invention is to provide an intercondylar osteotomy guide, which is adapted to the intercondylar osteotomy plate. The intercondylar osteotomy guide includes a locking structure and a positioning structure; the positioning structure is detachably arranged on the intercondylar osteotomy plate, and is used to define an osteotomy guide groove together with the intercondylar osteotomy plate; The locking structure is used for detachably connecting the positioning structure to lock the positioning structure and the intercondylar osteotomy plate. When in use, the osteotomy tool passes through the osteotomy guide groove for osteotomy, and during the osteotomy process, the osteotomy guide groove is used to limit the direction of the osteotomy tool, so that the osteotomy tool will not be vibrated during the osteotomy process. Deviations occur to ensure the stability and accuracy of the osteotomy, as well as the surgical effect and the stability of the prosthesis in the later stage. Additionally, the osteotomy tool includes, but is not limited to, an oscillating saw.
所需理解，现有的一些髁间截骨板自身未设置截骨槽，而是在中间位置开设一个U形缺口，截骨工具如摆锯沿着U形缺口的中间边缘向下截骨，而在截骨工具的另一相对侧无任何挡位，因此截骨工具容易前后晃动，难以保证截骨的稳定性。另有一些髁间截骨板即使自带截骨槽，但因为中间槽的影响，会导致两侧截骨不全的问题，因此目前市面上主要使用不带截骨槽的髁间截骨板。而本实用新型提供的髁间截骨导向器主要适配不带截骨槽的髁间截骨板，且当截骨工具截完第一刀后，只要从髁间截骨板上取下髁间截骨导向器，髁间截骨板不影响后面第二刀和第三刀的截骨，因此确保了髁间截骨板的中间侧和两侧的完整截骨。It should be understood that some existing intercondylar osteotomy plates themselves do not have an osteotomy groove, but a U-shaped notch in the middle position, and an osteotomy tool such as a pendulum saw cuts the bone downward along the middle edge of the U-shaped notch. However, there is no block on the opposite side of the osteotomy tool, so the osteotomy tool is easy to shake back and forth, and it is difficult to ensure the stability of the osteotomy. There are also some intercondylar osteotomy plates with osteotomy grooves, but due to the influence of the middle groove, it will lead to the problem of incomplete osteotomy on both sides. Therefore, currently on the market, intercondylar osteotomy plates without osteotomy grooves are mainly used. However, the intercondylar osteotomy guide provided by the utility model is mainly adapted to the intercondylar osteotomy plate without the osteotomy groove, and after the osteotomy tool cuts the first cut, the condyle is only required to be removed from the intercondylar osteotomy plate. The intercondylar osteotomy guide, the intercondylar osteotomy plate does not affect the osteotomy of the second and third knife behind, thus ensuring the complete osteotomy on the medial and bilateral sides of the intercondylar osteotomy plate.
在具体实施时，所述定位结构可设置定位槽，所述定位槽用于套设在所述髁间截骨板的侧挡墙上即可。此外，所述定位槽具有两相对的侧壁，所述侧挡墙具有相对的外侧面和内侧面；所述定位槽的一个侧壁用于与所述侧挡墙的外侧面贴合，另一个侧壁至少部分用于与所述侧挡墙的内侧面形成间隙，所述间隙即作为截骨导向槽使用。所述定位槽可以是四周均封闭的结构，还可以是具有开口的结构，只要保证定位槽的两相对侧壁在截骨工具的两相对侧进行挡位即可。In a specific implementation, the positioning structure may be provided with a positioning groove, and the positioning groove may be sleeved on the side retaining wall of the intercondylar osteotomy plate. In addition, the positioning groove has two opposite side walls, and the side blocking wall has opposite outer and inner sides; one side wall of the positioning groove is used to fit with the outer side of the side blocking wall, and the other One side wall is at least partially used to form a gap with the inner surface of the side retaining wall, and the gap is used as an osteotomy guide groove. The positioning groove may be a structure with all sides closed, or may be a structure with an opening, as long as the two opposite side walls of the positioning groove are in gear on the two opposite sides of the osteotomy tool.
以下结合附图以及优选实施例对本实用新型提出的髁间截骨导向器作进一步的说明。在不冲突的情况下，下述的实施方式及实施方式中的特征可以相互补充或相互组合。The intercondylar osteotomy guide proposed by the present invention will be further described below with reference to the accompanying drawings and preferred embodiments. The following embodiments and features in the embodiments may complement each other or be combined with each other without conflict.
