SURGICAL INSTRUMENT FOR STAPLE APPLICATION, WHICH CONTAINS MULTIPASS DRIVING STARTING MECHANISM WITH ROTARY MANUAL DEFLECTION SYSTEM WITH OPPOSING SPRING Russian patent published in 2011 - IPC A61B17/68 

FIELD: medicine.

SUBSTANCE: invention relates to medicine and can be used for endoscopic operations. Surgical instrument for application of staples and cutting contains handle which makes separate closing and actuation movements for bringing into action of terminal effector. In particular, handle makes several actuation motions in order to reduce value of effort necessary for actuation (i.e. sewing with staples and cutting off) with terminal effector. Composite transmission reduces required longitudinal handle dimension, however, ensures rigid strong construction in straightened state for actuation. Driving mechanism for actuation with friction tightening excludes sticking in bringing into motion said straightened composite rack in interaction with mechanism of reverse motion blocking, which prevents release of closing lever during actuation. External indicator plays role of feedback for proving the surgeon with information about degree of actuation progress, and also provides possibility of manual withdrawal.

EFFECT: surgical instrument for application of staples has multi-pass driving mechanism of actuation with automatic withdrawal after full advance of actuation.
