适用于磁压榨吻合的平移钳的设计.

Objective: The structural design scheme of the parallel moving clamp which can be used for the clamping and fixing of the magnet in the magnetic pressing anastomosis operation is proposed. Methods: The shortcomings and deficiencies of the original magnetic compression anastomosis technology of our team were analyzed, the magnets that magnetic compression anastomosis operation need by hand alone or by using the existing vascular forceps clamping and fixing, and it is the main reason of inconvenience in operation.From the mechanics point of view, analyzed the reason of the conventional vascular forceps hold the magnet can lead to the slippage of the magnet. And pointed out that the design and processing of magnetic anastomosis dedicated forceps is an effective measure to solve the problem of the inconvenience during magnetic anastomosis. On this basis, the structural design scheme of using the parallel moving clamp to fix the magnet is proposed. The mechanics analysis of the magnet is made. The parallel moving clamp with the magnets for clamping and fixing in the magnetic compression anastomosis are designed. Results: The structural design of the parallel moving clamp can stably clamp the magnet and prevent the magnet from slipping off. Meanwhile, the parallel movement of the clamp head can be controlled by the gear transmission structure to better control the precise attract and separation of the magnet, thereby further simplifying the operation, avoiding the unnecessary damage and saving operation time. Conclusions: The parallel moving clamp can be a variety of shapes and sizes to meet the magnet clamping and fixing, it can effectively control the magnet pull and separation, facilitate the operation.The parallel moving clamp processing simple, easy to use, and will promote magnetic compression anastomosis technology widely carried out in the clinic.
