The invention discloses a handheld minimally invasive medical surgical instrument with a multi-degree-of-freedom motion control function. Compared with the prior art, when an opening/closing button, afirst starting/stopping button or second starting/stopping button is pressed, a tail end execution device or a flexible wrist joint can be correspondingly driven to execute corresponding actions respectively, the opening/closing button, the first starting/stopping button and the second starting/stopping button do not influence one another and have independent degrees of freedom, therefore, medical workers do not worry about mutual interference generated by the control over each mechanism when performing the instrument; because button control is adopted, the instrument is simpler to operate and easy to use; in addition, the clamping action of the tail end execution device cooperates with the deflection action and rotation action of the flexible wrist joint so that the instrument can be suitable for most control sc
