A filter includes a filter frame and at least two resonators. A receiving space is formed in the filter frame. The at least two resonators are disposed in the receiving space and distributed along a signal transmission path. Adjacent resonators on the signal transmission path are coupled. Each resonator includes a body part and a bending part. One end of the body part is grounded. The bending part includes a head bending part and an end bending part, the head bending part being connected to the end bending part to form a resonator structure circulating in a counterclockwise or clockwise direction.

Filter

A single-layer cross-coupling filter includes a cavity in which a receiving space is formed; an integrally formed resonant structure installed in the receiving space; and at least one partition wall. The resonant structure includes at least two rows of resonant units distributed along a signal transmission path. The at least two rows of resonant units are located in a same plane of the receiving space, and each row of the resonant units includes a plurality of resonators. The resonators on a same row are coupled and connected to form signal transmission, and at least two adjacent resonators in different rows are coupled and connected to realize cross-coupling.

Single-layer cross-coupled filter

This application provides a driving switching mechanism for a stapling instrument. An actuation driving assembly includes a driving sleeve for driving an end effector to perform a closing action and a knife bar driving rod for driving the end effector to perform a stapling action. A handle driving assembly includes a driving handle and a knife bar driving assembly which includes a knife driving member and a handle driving connecting member. The handle driving connecting member is connected to a handle driving portion. The knife driving member is movably connected to the handle driving connecting member, and is movable relative to the handle driving connecting member to a driving position or a driving disengagement position. When the knife driving member is in the driving position, the knife driving member and the knife bar driving rod are engaged as the handle driving portion moves toward a second position.
