技术领域technical field
本实用新型涉及医疗器械领域，尤其是一中空形截骨板系列。The utility model relates to the field of medical instruments, in particular to a series of hollow osteotomy plates.
背景技术Background technique
第一跖骨基底部截骨术、第一跖楔关节融合术、外侧柱延长、跟骰关节融合术、骰骨截骨术为足踝外科常用手术方式。广泛用于严重拇外翻、先天性或成人获得性扁平足、陈旧性Lisfranc损伤等。患者病情复杂、足踝部畸形严重，手术难度大、技术要求高。截骨完成后需撑开一定宽度，矫形满意后使用钢板螺钉固定。但由于目前市场上使用的钢板附带有金属填塞块或钢板本身阻碍植骨，不利于手术顺利进行。同时由于金属填塞块阻挡，截骨处骨愈合空间减小，愈合时间长，术后病情恢复慢。另外金属填塞块宽度固定，不利于矫形精确性。Osteotomy of the base of the first metatarsal bone, fusion of the first metatarsal wedge joint, lengthening of the lateral column, fusion of the calcaneocuboid joint, and osteotomy of the cuboid bone are commonly used in foot and ankle surgery. Widely used in severe hallux valgus, congenital or adult acquired flat feet, old Lisfranc injury, etc. The patient's condition is complicated, the foot and ankle deformity is serious, the operation is difficult and the technical requirements are high. After the osteotomy is completed, it needs to be stretched to a certain width, and after the orthopedic is satisfactory, it is fixed with plates and screws. However, since the steel plates used in the market are attached with metal tampons or the steel plate itself hinders bone grafting, it is not conducive to the smooth operation of the operation. At the same time, due to the blocking of the metal packing block, the bone healing space at the osteotomy site is reduced, the healing time is long, and the postoperative recovery is slow. In addition, the width of the metal filling block is fixed, which is not conducive to the accuracy of orthopedics.
实用新型内容Utility model content
