The invention relates to the field of medical instruments, and discloses a constant-force power assisting device, a lifting mechanism and a patient surgery operation platform. The constant-force power assisting device comprises a fixing frame and a roller which is supported by the fixing frame and can rotate, a constant-force spring is arranged on the roller, the first end of the constant-force spring is wound on the roller, and a connecting part used for being connected with a moving part is arranged at the second end of the constant-force spring. Wherein the connecting part is provided with an initial fixing site relative to the fixing frame, and when the connecting part is located below the initial fixing site, the second end of the constant-force spring is in a stretching state and can provide constant force for the moving part within a set stroke range; when the constant-force power assisting device is used in a lifting mechanism and a patient surgery operation platform, the lifting device can ascend and descend gently, the speed of a moving part is effectively prevented from being out of control in the falling process, the motor load is relieved, the motor is protected, and the service life of the motor is prolonged.
本发明涉及医疗器械领域,公开了一种恒力助力装置、升降机构及患者手术操作平台。本发明中的恒力助力装置,包含有固定架,以及通过固定架支撑且可转动的滚轮,所述滚轮上设有恒力弹簧,所述恒力弹簧的第一端绕设在滚轮上,恒力弹簧的第二端上设有用于连接移动部件的连接部;其中,所述连接部相对于固定架具有一初始固定位点,于所述连接部位于初始固定位点下,所述恒力弹簧的第二端处于拉伸状态且能够为移动部件在设定行程范围内提供恒力;升降机构和患者手术操作平台中使用本发明所提供的恒力助力装置,能够使升降装置升降平缓,有效防止移动部件下落过程中速度失控,减轻电机负荷,保护电机,延长电机使用寿命。
