Abstract
An instrument used for brachytherapy delivery in the treatment of cancer by radiation therapy including a handle having first and second handle actuators; an end effector; and an instrument shaft that connects the handle with the end effector. The end effector has first and second adjacent disposed staple cartridges that each retain a set of staples. The first mechanism is for holding standard staples in a first array, and dispensing the standard staples under control of the corresponding first handle actuator. The second mechanism is for holding radioactive source staples in a second array, and dispensing said radioactive source staples under control of the corresponding second handle actuator. The actuating device is removably attachable to an actuator arm on a proximal end. A staple applicator cartridge holder is attached to the actuator arm on a distal end. The staple applicator cartridge is mountable in the holder and having a plurality of slots for mounting of radioactive source staples therein. An anvil therein crimps the staples.
