  • Publication number: 20220054156
    Abstract: A slide slot type multi-arm clamp includes a handle, a catheter, a clamping portion, a spring tube and a control line. In practical applications, a surgical operator applies an axial thrust and a pulling force to the handle to drive the control line to move, so as to open/close and lock the clamping portion. Moreover, side clamp arms and a clamp base in the clamping portion can be easily separated from the catheter or the spring tube to stay in a human body so as to achieve the functions of hemostasis and tissue suture. The side slot type multi-arm clamp can achieve the effect of minimizing the length of the instrument retained in the human body by the cooperation between the side clamp arms and the clamp base.

  • Patent number: 11194861
    Abstract: The method of the present disclosure includes: after a graph partitioning apparatus extracts an edge, first determining whether an aggregation degree between a currently extracted edge and an allocated edge in a first device satisfies a preset condition; then, when the preset condition is satisfied, determining whether a quantity of allocated edges stored in the first device is less than a first preset threshold; and allocating the currently extracted edge to the first device when the quantity is less than the first preset threshold. In this way, an aggregation degree between allocated edges in each device is relatively high and each device has relatively balanced load. When an edge changes and an edge associated with the particular edge needs to be synchronized, a relatively small quantity of devices need to perform synchronization and update, so that costs of communication between devices are reduced, and distributed graph computing efficiency is improved.
