Circular stapler with frictional reducing member |
摘要 |
A circular stapling instrument is provided which includes a reciprocating drive shaft and a firing bar. The reciprocating drive shaft has a first engagement member at a tip of the reciprocating drive shaft and a threaded adjustment member at a base of the reciprocating drive shaft. The firing bar is movably connected at a first end with a firing trigger and movably connected at a second end with a stapling head assembly through a second engagement member. The firing bar forms a first engagement surface which faces a respective second engagement surface formed on the reciprocating drive shaft. The circular stapling instrument also includes a frictional reducing member located in between the first and second engagement surfaces in order to reduce friction between the reciprocating drive shaft and the firing bar. |
