AI Technical Summary
The use of arc-shaped laparoscopic cutting staplers can easily lead to inaccurate cutting positions and asymmetrical anastomosis, especially in minimally invasive surgery. Due to uneven tissue hardness, curvature, or mismatch between the device model and the thickness of the lesion tissue, the risk of displacement is increased.
A self-positioning anti-deviation structure is added, including a moving chamber seat, a fixed chamber seat, a directional arc sleeve, a directional circular block, a differential diameter spring, and an electromagnetic component. Through the guide groove, the guide groove width design, electromagnetic transmission, and wedge surface transmission, the movement path of the cutting blade and the staple cartridge is stabilized, ensuring the accuracy of cutting and fitting.
It achieves precise control of the cutting blade and staple cartridge, avoiding the impact of cutting path deviation on the mating action and improving the accuracy of cutting and mating.
