A swing head mechanism and a medical stapler. The swing head mechanism comprises a rotating component, a swing head pull rod (), and a housing. At least one first fitting member and at least one second fitting member are respectively provided on the outside of the rotating component and the inside of the housing. When the rotating component rotates relative to the housing until the first fitting member is opposite to the second fitting member, the first fitting member and the second fitting member form an elastic embedding fit. The swing head mechanism facilitates an operator to set different swing angles of a stapler head portion, and can avoid uncontrollable swing of the stapler head portion.

Rotating mechanism and surgical stapler

A power tool comprises a housing (), a motor () provided inside the housing and for outputting rotary power, and an output shaft () driven by the motor to rotate. The output shaft has an output end connected to a drill bit () and a second end provided on the other end of the output shaft; in a non-working state, the output shaft can axially move relative to the housing along the output shaft; and in a working state, the output shaft is limited in moving in a first axial direction, the first axial direction being an axial direction from the output end to the second end. The drill bit of the power tool can extend in different length according to different positions of the output shaft, so that a working mode is rapidly switched in different working conditions, especially in a small space.
