Abstract
The present disclosure relates to the technical field of medical instruments, in particular to a series of instruments for exposure of lesions posterior to talus dome, including: a lesion exposure spreader configured to spread an ankle joint, a retractor configured to laterally retract tissue, and a talus lesion bone extractor configured for lesion debridement and bone extraction. The lesion exposure spreader includes a fixed handle. A supporting strip is fixedly arranged on one side of the fixed handle. A movable handle and a locking mechanism are slidably connected to the supporting strip. Fixing nails are arranged at the tail ends of the fixed handle and the movable handle. The retractor includes a retractor handle. The tail end of the retractor handle is bent and extends downwards, and the bent and extending part is a retractor blade. The talus lesion bone extractor includes a round bone extraction rod and a steering rod. The steering rod is detachably connected to the head end of the round bone extraction rod. A bone cutting end and a bone extraction section are sequentially arranged at the tail end of the round bone extraction rod. The bone cutting end is a conical annular cutting edge. A bone extraction groove is formed in the side wall of the bone extraction section. The bone extraction groove is communicated with the bone cutting end, and a bone block cut by the bone cutting end is extracted from the bone extraction groove. According to the present disclosure, lesion exposure and surgery field illumination are increased.
