Automatic anastomat

Abstract

The invention discloses an automatic anastomat. The automatic anastomat comprises a main shell, a rack, a gear shifting piece, a fixed driving wheel, a movable handle, a percussion gear set meshed with the fixed driving wheel to drive the rack to feed, and a tool retracting gear set meshed with the fixed driving wheel to drive the rack to retract. The fixed driving wheel and the gear shifting piece are rotationally connected with the main shell through a gear shaft; the movable handle is used for driving the fixed driving wheel to rotate; the percussion gear set and the tool retracting gear set are fixed to the gear shifting piece and located on the two sides of the fixed driving wheel respectively; and the first end of the rack is provided with a tool retracting switch which drives the gear shifting piece to rotate to only enable the tool retracting gear set to be meshed with the rack, and the second end of the rack is provided with a percussion switch which drives the gear shifting piece to rotate to only enable the percussion gear set to be meshed with the rack. According to the automatic anastomat, percussion and tool retracting can be automatically switched, and tissue is prevented from being pulled back and retracted manually.

Description

technical field [0001] The invention relates to the field of surgical medical instruments, in particular to an automatic stapler. Background technique [0002] Laparoscopic linear cutting stapler is mainly used by medical institutions for resection, transection and anastomosis of lung, stomach and intestinal tissue in laparoscopic surgery. Laparoscopic linear cutting stapler is a kind of medical device commonly used in surgery. Simple, fast suturing and few side effects and surgical complications are favored and respected by clinical surgeons at home and abroad. [0003] The current stapler stays in the firing position after the cutting is completed. If the firing continues, there is a risk that the cutting knife will break, or the instrument itself will be damaged, and the knife cannot be pulled back, causing fatal injury to the patient. Secondly, if you want to To complete the knife retraction operation, it must be pulled back manually, which requires two-handed operation...

If the firing continues, there is a risk that the cutting knife will break, or the instrument itself will be damaged, and the knife cannot be pulled back, causing fatal injury to the patient. Secondly, if you want to After completing the knife retraction operation, it must be pulled back manually, which requires two-handed operation, which is not easy enough. At the same time, there is a risk of pulling the tissue due to the clamping of the tissue during the pull-back operation
