FIELD: medicine.
SUBSTANCE: surgical instrument includes an end effector and an input drive rod that closes the actuator and/or the actuating drive. The end effector contains a branch assembly. The assembly includes the first branch element and the second branch element. The end effector contains an I-element that is translationally moved axially between the proximal position and the distal position within the end effector. The input drive rod is configured to selectively engage with the actuating drive and/or the closing actuator. The closing actuator is in threaded engagement with the actuating drive, which allows the input drive rod to simultaneously move the closing actuator and the actuating drive during the start-up stroke until the closing actuator is disengaged from the actuating drive. With the reverse stroke, the closing actuator can again be engaged with the actuating drive.
EFFECT: reliability increase.
