本发明涉及外科器械技术领域,尤其涉及一种单髁置换手术个性化智能导航定位装置及方法。The invention relates to the technical field of surgical instruments, in particular to a personalized intelligent navigation and positioning device and method for unicondylar replacement surgery.
背景技术Background technique
全膝关节置换术是治疗终末期膝关节骨关节炎的有效方法,但是对单纯一侧胫股关节间室退变严重而对侧间室无任何疼痛不适的病例,有学者推荐膝关节单髁置换术,其目的是替换胫股关节受破坏的软骨表面。与胫骨高位截骨及全膝关节置换术相比,单髁置换术具有创伤小、恢复快、费用少以及对翻修影响小等优势。Total knee arthroplasty is an effective method for the treatment of end-stage knee osteoarthritis. However, in the case of severe degeneration of one tibiofemoral joint compartment without any pain and discomfort in the contralateral compartment, some scholars recommend unicondylar knee joint Replacement surgery, the purpose of which is to replace the damaged cartilage surface of the tibiofemoral joint. Compared with high tibial osteotomy and total knee arthroplasty, unicondylar replacement has the advantages of less trauma, faster recovery, less cost, and less impact on revision.
由于早期假体工艺及设计方面的缺陷,单髁置换术很长一段时间不被临床所接受。近几年,随着手术技术、假体设计的改进及手术指征的明确,单髁置换术的应用获得了良好的近期疗效。但单髁置换术在假体安放和力线方面并无统一标准,而假体植入位置不准确是影响假体生存率非常重要的影响因素。Due to defects in early prosthesis technology and design, unicondylar replacement was not accepted clinically for a long time. In recent years, with the improvement of surgical technique, prosthesis design and clear surgical indications, the application of unicondylar replacement has achieved good short-term curative effect. However, there is no uniform standard for prosthesis placement and alignment in unicondylar replacement, and inaccurate implant placement is a very important factor affecting the prosthesis survival rate.
传统的关节置换术主要依靠截骨导板配合机械对线系统完成截骨、假体安放和肢体力线控制,其精确性在很大程度上依赖于术者的经验,需凭借手术医生的经验和手感定位解剖标志,存在主观误差,因此,亟需一种单髁置换手术个性化智能导航定位装置及方法,来准确的确定截骨方向,确保截骨精度。The traditional joint replacement mainly relies on the osteotomy guide and the mechanical alignment system to complete the osteotomy, prosthesis placement and limb alignment control. There are subjective errors in tactile positioning of anatomical landmarks. Therefore, a personalized intelligent navigation and positioning device and method for unicondylar replacement surgery is urgently needed to accurately determine the direction of osteotomy and ensure the accuracy of osteotomy.

下面结合图1-图8描述本发明的单髁置换手术个性化智能导航定位装置,该单髁置换手术个性化智能导航定位装置包括导板本体1,在导板本体1上设有截骨槽2和截面呈长方形的通孔3,截骨槽2的深度方向与通孔3的高度方向相同,截骨槽2的长度方向与通孔3的深度方向相同,截骨槽2的槽底高于通孔3的顶部,截骨槽2的截骨开口方向朝向导板本体1的顶部。其中,截骨槽2的截骨开口在屈曲位时指向髂前上嵴。The individualized intelligent navigation and positioning device for unicondylar replacement surgery of the present invention will be described below with reference to FIGS. 1 to 8 . The individualized intelligent navigation and positioning device for unicondylar replacement surgery includes a
在本实施例中,通过截骨槽2和通孔3来辅助进行精准的截骨,其中,由于截骨槽2在屈曲位时(膝盖弯曲时)指向髂前上嵴,能够使截骨更加精准,在截骨完成后,使假体能够精准的放置,避免截骨后假体放歪或悬空,若假体放歪或悬空则会在伸直和屈曲过程中导致假体磨损严重,会引起内侧软组织刺激疼痛,造成术后感染,还会增加假体边缘载荷导致半月板衬垫的过度磨损,还会导致骨支撑不足,使其受力不均而易发生无菌性松动,造成假体脱位和下沉,因此,通过本方案可以避免术中医生根据自身经验进行截骨而造成术后疼痛、假体脱位、松动、下沉、旋转对位不良和术后感染等并发症,提高了手术的成功率和假体的生存率。In this embodiment, precise osteotomy is assisted by the
其中,截骨槽2为矢状位截骨槽,在进行单髁胫骨截骨手术时,截骨槽2位于内侧髁间嵴的内侧斜坡上,此时截骨槽2可以起到很好的参考标志作用,且由于截骨槽2的上侧在导板本体1的顶部形成截骨缺口,可以十分便于利用摆锯14进行切割。Among them, the
膝关节在屈曲和伸直过程中,势必会伴随有胫骨相对于股骨的内外旋,倘若截骨精度不够,假体安装位置有放歪或悬空的可能,在屈曲和伸直过程中会引起内侧软组织刺激疼痛,甚至术后感染,同时,胫骨假体的悬空不仅会增加垫片边缘载荷导致半月板衬垫的过度磨损,还会导致骨支撑不足,使其受力不均而易发生无菌性松动,造成假体脱位和下沉。通过本方案中的截骨导板进行辅助截骨,可以精确的把握截骨方向,在截骨完成并进行假体放置后,可以使假体能更好的满足膝关节在屈曲和伸直过程中生理上的内外旋。In the process of flexion and extension of the knee joint, the tibia is bound to rotate internally and externally relative to the femur. If the osteotomy accuracy is not enough, the prosthesis installation position may be skewed or suspended, which may cause medial side effects during flexion and extension. Soft tissue irritation and pain, and even postoperative infection, at the same time, the suspension of the tibial prosthesis will not only increase the edge load of the shim and cause excessive wear of the meniscus liner, but also lead to insufficient bone support, making it uneven and prone to sterility. Sexual loosening, resulting in prosthesis dislocation and subsidence. Using the osteotomy guide in this scheme to perform auxiliary osteotomy, the direction of the osteotomy can be accurately grasped. After the osteotomy is completed and the prosthesis is placed, the prosthesis can better satisfy the knee joint in the process of flexion and extension. Physiological internal and external rotation.
通孔3的结构可以使通孔3的两端均为封闭设计,如图1所示,通孔3的左侧位于靠近截骨槽2下侧的位置,通孔3的右侧为封闭设置,如图1可知,通孔3的左侧也为封闭设置。将通孔3的右侧设置为封闭状态,可以避免在手术过程中由于保护不到位而伤及内侧副韧带。The structure of the through
根据本发明提供的单髁置换手术个性化智能导航定位装置,通孔3的第一侧壁10在通孔3高度方向的投影位于截骨槽2的第二侧壁11和第三侧壁12在截骨槽2深度方向的投影区域之间。具体的通孔3的第一侧壁10可以与截骨槽2的第二侧壁11的投影重合。利用这样的方式可以使摆锯14通过截骨槽2和通孔3进行切割后,其中一侧的切割位置相适配,更好的保证精确的截骨。According to the personalized intelligent navigation and positioning device for unicondylar replacement surgery provided by the present invention, the projection of the
其中,导板本体1用于与胫骨相连的一侧为拟合连接侧,拟合连接侧在第一高度位置处设置有第一拟合部4和第二拟合部5,拟合连接侧在第二高度位置处设置有第三拟合部6,在第一拟合部4和第二拟合部5之间形成截骨槽2。如图1和图2所示,第一拟合部4、第二拟合部5和第三拟合部6的连接面的形状与胫骨相对应的位置的形状相同,第一拟合部4、第二拟合部5和第三拟合部6用于与相对应的胫骨区域精准拟合,实现导板本体1与胫骨之间精准连接。Wherein, the side of the

接下来,对单髁置换手术个性化智能导航定位装置的规划方法进行示例性说明。Next, the planning method of the personalized intelligent navigation and positioning device for unicondylar replacement surgery is exemplified.
首先,根据患者骨模型确定胫骨机械轴(膝关节中心至踝关节中心连线),进而确定横断面,其中,横断面垂直于机械轴;First, determine the mechanical axis of the tibia (the line connecting the center of the knee joint to the center of the ankle joint) according to the patient's bone model, and then determine the cross section, where the cross section is perpendicular to the mechanical axis;
然后,根据后交叉韧带中点到胫骨结节内侧缘连线确定Akagi线,确定矢状面;Then, the Akagi line was determined according to the line connecting the midpoint of the posterior cruciate ligament to the medial border of the tibial tubercle, and the sagittal plane was determined;
其次,在失状位上测量患者胫骨内侧后倾角,其中,胫骨内侧后倾角一般为0-7°;Second, measure the patient's medial tibia retroversion angle in the deviated position, where the medial tibia retroversion angle is generally 0-7°;
再次,确定通孔的位置,即沿通孔进行横向截骨的方向与患者胫骨后倾角保持一致,截骨厚度距离平台内侧最低点2-5mm;Third, determine the position of the through hole, that is, the direction of transverse osteotomy along the through hole should be consistent with the posterior inclination angle of the patient's tibia, and the thickness of the osteotomy is 2-5mm from the lowest point on the inner side of the platform;
最后,确定截骨槽的位置,即沿截骨槽进行失状位截骨的方向在膝关节处于屈曲位时指向髂前上嵴,截骨位置位于距内侧髁间嵴1-2mm;根据通孔和截骨槽的位置,设计生成完整的单髁置换手术个性化智能导航定位装置的模型,通过该模型进行3D打印,制成本发明的单髁置换手术个性化智能导航定位装置。Finally, determine the position of the osteotomy groove, that is, the direction of the deviated osteotomy along the osteotomy groove points to the anterior superior iliac crest when the knee joint is in the flexed position, and the osteotomy position is located 1-2 mm away from the medial intercondylar ridge; The position of the hole and the osteotomy slot is designed to generate a complete model of the personalized intelligent navigation and positioning device for unicondylar replacement surgery, and the model is 3D printed to make the personalized intelligent navigation and positioning device for unicondylar replacement surgery of the present invention.
