FIELD: medicine.
SUBSTANCE: invention relates to medical equipment, specifically to a surgical stapling device. Surgical stapling device comprises end effector, a shaft assembly and a drive member. End effector staple driver is configured to advance distally along the end effector. Drive member of the shaft assembly is translatable in communication with the staple driver. Drive assembly in communication with the drive member is translatable and comprises a motor, a rotary drive member in communication with the motor, a first link in communication with the rotary drive member, a first toggle link in communication with the first link and a second toggle link in communication with the first link. Toggle link is connected with the translatable drive member. Second toggle link is connected to a mechanical support. Rotation of the rotary drive member leads to the initiation of linear movement in the first link. First link is configured to rotate the second toggle link relative to the mechanical support and the first toggle link relative to the drive member. Drive member is translatable, thereby straightening the first and second toggle links for transferring the linear movement to the drive member, which is not parallel to the linear movement of the first link.
EFFECT: positioning of a surgical instrument through an opening in the patient’s body and the use of the instrument for adjusting, positioning, attaching and other interaction with the tissue inside the patient’s body.
