Abstract:
Objective To design and evaluate a dilation incision device capable of facilitating stable support and flexible adjustment during neurosurgical procedures.Methods The dilation incision device was composed of a support plate,an adjustment assembly,a brain support ring,a rotation assembly,an electric motor,an expansion assembly and a neck support ring.The support plate was made of high-strength stainless steel;the adjustment assembly was made up of a first screw,a lifting groove,a slide bar and a nut;the brain support ring was fixed to the adjustment assembly through a support rod,with an outer layer of medical-grade silicone and an inner layer of stainless steel skeleton;the rotation assembly connected the brain support ring with the expansion assembly and consisted of a rotating shaft,a connecting rod and a rotating lug;a high-precision direct current servo motor was selected for the device;the expansion assembly included a spring,an expansion plate and a moving plate,which realized auto expansion or contraction through spring pressure;the neck support ring had its outer layer made of flexible polyurethane foam and inner layer being a stainless steel skeleton.The device had its stability and safety evaluated by static and dynamic tests at different heights(50,100,150 mm)and angles(0°,30°,60°),which was compared with the traditional fixation device to verify its application effect.Results Static and dynamic tests indicated the device showed high stability and safety in different heights and angles,and gained advantages over the traditional device in stability,convenient operation and surgical field visualization.Conclusion The device developed meets the requirements of neurosurgical procedures,and enhances the safety and portability of neurosurgical procedures.[Chinese Medical Equipment Journal,2024,45(10):37-40]
