FIELD: medicine.
SUBSTANCE: stapler for circular clip application includes a drive shaft coupled to the trigger actuation of which causes drive shaft rotation. The distal portion of the drive shaft is held in the articulated arm holding the swivel clips. Upon trigger mechanism actuation, the drive shaft is rotated to ensure placement of the said staples distally outwardly from the articulated arm. The drive shaft comprises a cable, where a plurality of drive units is located at intervals along the axis, adapted to convert rotary motion of the drive shaft to staples rotation.
EFFECT: improved mechanism operation.
