技术领域Technical field
本发明涉及全膝关节置换术医疗辅助器械技术领域，具体涉及一种膝关节手术用导板精度验证装置及其验证方法。The invention relates to the technical field of medical auxiliary equipment for total knee replacement surgery, and in particular to a guide plate accuracy verification device for knee joint surgery and a verification method thereof.
背景技术Background technique
膝关节置换截骨导板是一种手术辅助工具，利用该导板，无需开髓即可完成手术过程，能够有效减少手术创伤，精简术中使用的工具，提升手术效率；同时能够缩短医生学习曲线，确保手术效率和质量；而且导板还是根据不同患者的骨质而个性化定制的，对于手术的准确性大大提高。当前最常用的膝关节置换截骨导板主要有股骨导板4和胫骨导板6(参考图3-图5)。The knee replacement osteotomy guide is a surgical auxiliary tool. The guide can be used to complete the surgical process without opening the marrow. It can effectively reduce surgical trauma, streamline the tools used during the surgery, and improve surgical efficiency. It can also shorten the doctor's learning curve. Ensure the efficiency and quality of surgery; and the guide plate is customized according to the bone quality of different patients, which greatly improves the accuracy of surgery. Currently, the most commonly used knee replacement osteotomy guide plates mainly include femoral guide plate 4 and tibial guide plate 6 (refer to Figures 3-5).
目前截骨导板多是采用尼龙打印，并经过后续处理后完成，对于在术中所需使用的各个定位孔及截骨槽位置，能够达到一定的准确程度，但为确保在术中对患者使用时顺利进行，仍需对定位孔孔距及截骨面距离进行精确性验证。At present, most osteotomy guides are printed with nylon and completed after subsequent processing. The positions of various positioning holes and osteotomy slots required during the operation can reach a certain degree of accuracy. However, in order to ensure that they can be used on patients during the operation. It is carried out smoothly, but the accuracy of the distance between the positioning holes and the distance between the osteotomy surfaces still needs to be verified.
现有技术中，通常由人工操作游标卡尺进行孔距及截骨面距离的验证，此验证方法往往误差相对较大，且费时费力，尤其是批量验证时，工作效率很低。因此，为了提高工作效率，增加验证的准确性，现亟需一种导板精度验证工装。In the existing technology, manually operated vernier calipers are usually used to verify the hole distance and osteotomy surface distance. This verification method often has relatively large errors and is time-consuming and labor-intensive. Especially during batch verification, the work efficiency is very low. Therefore, in order to improve work efficiency and increase the accuracy of verification, a guide plate accuracy verification tool is urgently needed.
