Abstract

The surgical binding instrument includes a bent tube, a nail anvil, a nail barrel assembly, a feeding trigger gun, and a feeding trigger clutch with repositioning spring. The feeding trigger gun has a casing, a lining sleeve with end extending beyond the casing, a driven rod inside the lining sleeve, a connecting sleeve, a connecting rod connected to the driven rod and the driving rod, a feeding triggering mechanism on the driven rod linked with the feeding trigger clutch, an axial slot for the driving rod to shift in the middle part of the lining sleeve, a driven rod locking mechanism connected to the handle, a switcher in the back section of the driven rod, and a feeding switch mechanism between the driving rod and the driven rod.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical binding instrument, especially a surgical binding instrument. technical background [0002] At present, domestic and foreign surgical stapling instruments use a moving mechanism with tail screw adjustment or double screw adjustment, plus a single-handle or double-handle firing anastomosis mechanism. In the process of thread adjustment, the speed control is always unsatisfactory. It cannot achieve the effect of fast forward before the fit, slow adjustment, and quick exit after the fit. In addition, the amount of hands used in the whole process is too complicated, and the hands have to be switched continuously. position, prolonging the operation time, etc. Contents of the invention [0003] The purpose of the present invention is to provide a kind of stapler for the anastomosis of circular broken ends (such as the broken ends after intestinal resection) in the surgical operation in ...
