技术领域technical field
本发明涉及医用领域，特别是涉及一种近指间关节融合对位器。The invention relates to the medical field, in particular to a proximal interphalangeal joint fusion aligner.
背景技术Background technique
在手外伤患者中，近指间关节损伤，需要行关节融合的并不少见。为了使患指最大程度地保留功能，常常将其融合于功能位（30°左右）。以往术中常常根据术者的经验进行关节的融合。难免会出现融合角度的偏颇，甚至出现指体的侧方移位。针对以上问题，设计一种近指间关节融合对位器，使近指间关节融合时，角度更精确，同时也可以避免指体侧方移位的出现。In patients with hand trauma, it is not uncommon for the proximal interphalangeal joint to require fusion. In order to preserve the function of the affected finger to the greatest extent, it is often fused to the functional position (about 30°). In the past, joint fusion was often performed according to the operator's experience. It is inevitable that there will be a biased fusion angle, and even a lateral displacement of the finger body. Aiming at the above problems, a fusion aligner for the proximal interphalangeal joint is designed to make the angle more accurate when the proximal interphalangeal joint is fused, and at the same time avoid the occurrence of lateral displacement of the finger body.
