Abstract

é apresentado um sistema de grampeamento cirúrgico que inclui um conjunto de haste que transmite movimentos de acionamento provenientes de um atuador e um atuador de extremidade que comprime e grampeia tecidos. o atuador de extremidade compreende uma canaleta; uma bigorna tendo uma superfície de formação de grampos que é móvel em relação à canaleta, entre uma posição aberta e uma posição fechada; a bigorna tendo um ímã na extremidade distal; e um cartucho de grampos posicionado de modo removível dentro da canaleta. o cartucho de grampos compreende um corpo suportado para uma relação confrontante com a bigorna em sua posição fechada; uma pluralidade de acionadores de grampo posicionados dentro do corpo do cartucho suporta um grampo; um sensor de efeito hall localizado na extremidade distal do corpo; e um microprocessador em comunicação com o sensor de efeito hall. o sensor de efeito hall e o microprocessador recebem energia quando o cartucho de grampos está posicionado dentro do canal, e o sistema é operável para identificar o cartucho de grampos.A surgical stapling system including a stem assembly that transmits drive motions from an actuator and an end actuator that compresses and staples tissues is presented. the end actuator comprises a channel; an anvil having a stapling surface that is movable with respect to the channel between an open position and a closed position; the anvil having a magnet at the distal end; and a staple cartridge removably positioned within the channel. the staple cartridge comprises a body supported for an anvil facing relationship in its closed position; a plurality of clip actuators positioned within the cartridge body support a clip; a hall effect sensor located at the distal end of the body; and a microprocessor in communication with the hall effect sensor. the hall effect sensor and microprocessor receive power when the staple cartridge is positioned within the channel, and the system is operable to identify the staple cartridge.
