Abstract

The invention provides a band-knife stitching instrument with an indicating device. The band-knife stitching instrument comprises a nail pushing plate and a jaw clamping plate and further comprises the indicating device which is fixed on the jaw clamping plate, wherein the indicating device comprises a fixed seat, a gear, a driving module, a stopping module and an indicating wheel; before the band-knife stitching instrument is used, the stopping module is not in contact with the gear; after the band-knife stitching instrument is closed, the driving module advances with the nail pushing plate and triggers the stopping module, so that the stopping module is in contact with the gear to stop the gear from rotating in a direction reverse to the rotation direction of the gear under the driving module; in the firing process of the band-knife stitching instrument, the gear is driven to rotate by the driving module; after once firing is finished, the driving module returns to a closing position with the nail pushing plate; and during refiring, the driving module advances again with the nail pushing plate and drives the gear to rotate.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a stapler with a knife with an indicating device. Background technique [0002] In the surgical operation of medical science, since the first staple product in the 1960s, the medical stapler has become an indispensable medical device in the process of suturing the knife edge. Various surgical medical staplers are widely used in surgical operations to suture human digestive tract tissues, respiratory tract tissues and vascular tissues, which can reduce operation time and improve operation quality. They are usually used for end-to-end, end-to-side, and side-to-side suture operations such as esophagus, stomach, duodenum, small intestine, colon, and rectum in the digestive tract, or operations for forming channels or closing incisions such as hemorrhoidectomy and gastric pylorostomy. It is used in the suture operation of the lung and trachea in the respiratory tract and the suture...
