  • Patent number: 12048432
    Abstract: A swing head mechanism and a medical stapler. The swing head mechanism comprises a rotating component, a swing head pull rod (93), and a housing. At least one first fitting member and at least one second fitting member are respectively provided on the outside of the rotating component and the inside of the housing. When the rotating component rotates relative to the housing until the first fitting member is opposite to the second fitting member, the first fitting member and the second fitting member form an elastic embedding fit. The swing head mechanism facilitates an operator to set different swing angles of a stapler head portion, and can avoid uncontrollable swing of the stapler head portion.

  • Patent number: 12048434
    Abstract: A computer-implemented method for controlling a surgical stapling instrument for stapling tissue includes advancing an anvil assembly in relation to a staple cartridge to a first position defining a tissue gap between the staple cartridge and the anvil assembly and clamping tissue, the clamped tissue including a suture, measuring a first force of tissue compression of the tissue clamped within the tissue gap with the anvil assembly at a first time point, determining whether the measured first force is greater than a threshold, measuring a second force of tissue compression of the tissue clamped within the tissue gap at a second time point in response to the determination that the first force is greater than the threshold, determining whether the suture failed based on the measured second force being an amount less than the measured first force, and stopping the advancing of the anvil assembly based on the determined suture failure.

  • Patent number: 12048480
    Abstract: A method and system for mapping tissue and producing lesions for the treatment of cardiac arrhythmias in a non-thermal and optimal manner, minimizing the amount of energy required to selectively stun or ablate the target tissues. Energy may be delivered only at the moment(s) of best device position and proximity of an electrode to target tissue, and only during a time in the cardiac cycle determined to be optimal for reversible or irreversible effects. A method may include determining timing of the cardiac cycle and an optimal time within the cardiac cycle for energy delivery, evaluating proximity between at least one energy delivery electrode and the target tissue, and delivering pulsed field energy from the at least one energy delivery electrode to the target tissue when, during the optimal time for energy delivery, the at least one energy delivery electrode is in close proximity with the target tissue.
