技术领域technical field
本实用新型涉及医疗领域，具体涉及一种可使深部术野清晰的且具有防脱钩功能的椎板拉钩。The utility model relates to the medical field, in particular to a lamina retractor which can make the deep surgical field clear and has the function of preventing decoupling.
背景技术Background technique
椎板拉钩广泛应用于腰椎后路手术中，传统的椎板拉钩前端只用一个拉钩在使用过程中容易发生脱钩，由于脊柱手术的创口一般会比较小又比较深，手术台上的无影灯有时不能达到深部术野，导致术野不清晰。由于脊柱手术属于精细手术，术野不清晰有损伤脊髓及神经根的风险，还会造成手术风险增加，延长手术时间增加患者的痛苦。手术过程中椎板拉钩的横臂难免会沾到手术过程中产生的液体，会使摩擦力减小使椎板拉钩操作困难。Lamina retractors are widely used in posterior lumbar surgery. Traditional lamina retractors only use one retractor at the front end, which is prone to decoupling during use. Since the wounds of spinal surgery are generally small and deep, the shadowless lamp on the operating table sometimes cannot Reaching the deep operative field, resulting in unclear operative field. Since spinal surgery is a delicate surgery, the unclear operative field may cause damage to the spinal cord and nerve roots. It will also increase the risk of surgery, prolong the operation time and increase the pain of the patient. During the operation, the transverse arm of the lamina retractor will inevitably be stained with the liquid produced during the operation, which will reduce the frictional force and make the operation of the lamina retractor difficult.
