Its defect is: when the circlip is connected to the positioning shaft, it is fixed by two circlips in the circlip, and there is no purse hole on the circlip to adjust the amount of resected tissue, and the cutting limit is large. Fix the positioning shaft, the connection is not firm and safe, loose, and the gap is large. When the doctor uses too much force when the staple enters the nail seat for forming, the medical accident of the connection failure is caused by excessive force. Bring inconvenience, cause operation failure, increase patient pain and doctor's workload

Description
technical field [0001] The invention relates to a connecting device of a disposable lead-in type anorectal hemorrhoid stapler, which is suitable for matching use with a disposable guiding type anorectal hemorrhoid stapler. Background technique [0002] In devices such as medical equipment, it is necessary to use a disposable introduction type anorectal hemorrhoid stapler. Its defect is that when the circlip is connected to the positioning shaft, it is fixed by two circlips in the circlip, and there is no purse hole on the circlip to adjust the amount of resected tissue, and the cutting limit is large. Since only two circlips are mirror images Fix the positioning shaft, the connection is not firm and safe, loose, and the gap is large. When the doctor uses too much force when the staple enters the nail seat for forming, the medical accident of the connection failure is caused by excessive force. Bring inconvenience, cause operation failure, increase patient's misery and docto...
