The invention relates to a percussion safety device and medical microscopic anastomat. The percussion safety device comprises a trigger, a reset component, a shifting pin and a spring. An insertion hole and a mounting hole are formed in the top of the front side of the trigger; the bottom of the reset component is inserted into the insertion hole; a via hole is formed in the top of the reset component and is particularly formed inside the mounting hole; the shifting pin is mounted on the top of the reset component; the spring is mounted inside the insertion hole and is butted to the bottom ofthe insertion hole by the bottom of the reset component; the spring is configured in such a manner that the shifting pin has movement tendency for being butted to the top wall of the mounting hole allalong, and the shifting pin can be in contact with the bottom wall of the mounting hole when the spring is in compressed states. The medical microscopic anastomat is provided with the percussion safety device. The percussion safety device and the medical microscopic anastomat have the advantages that the percussion safety device and the medical microscopic anastomat are easy to operate, convenient to use, high in use comfort and invulnerable to the problem of instrument damage due to misoperation, the stability and the safety of instruments can be guaranteed in use procedures, and the like.
Description
technical field [0001] The invention relates to the field of firing devices, in particular to a firing safety device and a medical endoscopic stapler. Background technique [0002] In some instruments with a firing device, for example, in a medical endoscopic stapler, in order to prevent misoperation or false firing, a firing safety device is provided before firing. [0003] The structure of the firing safety device in the prior art mainly adopts a double trigger structure, which needs to be pulled by the index finger to open the firing safety, but when operating, the small trigger must be pulled after the big trigger is pulled, and the small trigger must be pulled when pulling The trigger rotates to the position where the human forefinger can pull it, so there is a problem of inconvenient operation, and it is very easy to cause damage to the device due to the disordered sequence of pulling. Contents of the invention [0004] The present invention is proposed in view of t...
