Embodiment 1

[0041] (Embodiment 1, stapler main body)

[0042] See Figure 1 to Figure 4 , The main body of the stapler in this embodiment includes a shaft assembly 20 , a push rod assembly 30 , a staple cartridge assembly 40 , a housing assembly 50 , a handle assembly 60 , a control assembly 70 , a safety block assembly 80 , a pointer assembly 90 and a pressing bar 100 .

[0043] The connecting shaft assembly 20 includes a top shaft 21 , a middle shaft 22 , a rear shaft 23 and a rear pressing piece 24 all of which are made of steel. The central axis 22 is formed by stacking two integral steel belts; the rear axis is composed of an optical axis 23-1 and a screw mandrel 23-2 connected front and rear. The front ends of the two integral steel bands 22 are clamped at the rear end of the top shaft 21 , and the rear ends of the two integral steel bands 22 are clamped at the front end of the optical axis 23 - 1 of the rear shaft 23 .

[0044] The back pressing piece 24 is a U-shaped splint; the...

Embodiment 2

[0064] (Embodiment 2, stapler)

[0065] See Figure 1 to Figure 7 , the tubular stapler of this embodiment includes an anvil assembly 10, staples and a stapler main body. The main body of the stapler is obtained from Example 1.

[0066] The nail anvil assembly 10 includes a steel nail anvil 11 and a connecting sleeve 12 , and the connecting sleeve 12 is fixedly connected with the nail anvil 11 .

[0067]The usage process of the tubular stapler of this embodiment is: before the operation, staples are loaded into the staple cartridge cover 42 of the staple cartridge assembly 40 . During the operation, the head of the nail abutment seat assembly 10 of the stapler is inserted into the tubular tissue of the digestive tract from a side incision near a fracture of the human digestive tract tubular tissue to be sutured and protruded from the fracture, and then the nail abutment The seat assembly 10 stretches into another fracture, and a purse is tied on the connecting shaft sleeve ...

Abstract

The invention relates to a tubular stapler with a safety device and a stapler body. The stapler comprises a staple pressing seat component, a staple and a stapler body, wherein, the stapler body comprises a spindle component, a push rod component, a staple box component, a shell component, a movable handle, an adjusting nut, a safety block and an indicator. The stapler has an interlock function of the indication on a green zone by the indicator and the automatic start-up of the safety block. By observing the indication of the indicator on the green zone and the clang given by the safety blockfor automatic start-up, the stapler can give double hints to a clinician that an anastomosis zone is entered and the anastomosis distance can be continued to be slightly adjusted by considering the thickness of tissue, and then the clinician can move the movable handle to realize the anastomosis of cutting. Therefore, the tubular stapler can prevent the percussion beyond the predetermined scope and is convenient, safe and reliable in operation.
