【摘要】 目的探讨长骨骨折内固定术中交锁髓内钉瞄准器校正瞄准的应用效果。方法用可调式交锁髓内钉瞄准器与非可调式交锁髓内钉瞄准器在两个动物实验组(A、B组)中进行对比。结果可调式交锁髓内钉瞄准器在瞄准偏差的情况下,通过校正瞄准达到正确瞄准,非可调式交锁髓内钉瞄准器在瞄准偏差的情况下,无法校正瞄准,需改手工进行。结论可调式交锁髓内钉瞄准器有良好的适应性。更多还原

【Abstract】 Objective To explore the application method of calibration target-type interlvcking nail sighting device in long bone fracture fixation. Methods Adjustable calibration target-type interlocking nail sighting device and non-adjustable calibration target-typt interlocking nail sighting device were used in A group and B group respectively. Results Aiming deviation in A group can be corrected by sighting device, and the aiming deviation in B group can’t be corrected by sighting device, and switched to manual correction. Conclusion Adjustable calibration target-type interlocking nail sighting device has a good adaptability.更多还原
