Abstract
Disclosed is a surgical round tube type stapler with a quick adjustment device. Different from the method for adjusting a screw by using an adjusting button directly in prior art, a quick adjustment device of rotary sleeve type is disposed in a push device. Single-speed adjustment is modified to two-stage adjustment by a segment of big pitch worm and a segment of small pitch worm on the rotary sleeve to separate combination among parts of a stapler head to two stages of coarse adjustment and trimming adjustment. Closing of nail bin and nail-anvil assembly can be realized quickly based on accurate positioning and the operation time is shortened greatly. The disclosed stapler has a simple structure and will have a good application in surgical instrument domain.
