A surgical stapler includes an anvil and a cartridge that cooperate with each other, a handle, and a connecting tube for connecting the cartridge to the handle. A stent mounting rod is arranged at a front end of the anvil, and a stent for distracting an orifice is movably connected to the stent mounting rod. The stent has a flexible and deformable tubular structure and can distract a lumen of the human orifice after a radial constraint is removed. The stent is coated with an anti-leakage film. An anti-reflux film is further arranged on the stent. The surgical stapler can effectively solve some complications after anastomosis by an existing surgical stapler, and can be widely used in the technical field of medical anastomosis.

An equilibrium computation acceleration method and system for a sparse recurrent neural network determine scheduling information based on an arbitration result of sparsity of a weight matrix, select a computation submodule having operating voltage and operating frequency that match the scheduling information or a computation submodule having operating voltage and operating frequency that are adjusted to match the scheduling information, and use the selected computation submodule to perform a zero-hop operation and a multiply-add operation in sequence, to accelerate equilibrium computation. The equilibrium computation acceleration system includes a data transmission module, an equilibrium computation scheduling module with a plurality of independent built-in computation submodules, and a voltage-adjustable equilibrium computation module. An error monitor is configured to achieve dynamic voltage adjustment. The data transmission module quickly exchanges a configuration of a read/write memory to reduce additional data transmission.
