Description

Technical Field

[0001] The utility model belongs to the technical field related to medical auxiliary equipment, and particularly relates to a linear cutting stapler. Background Art

[0002] The stapler is a medical device that replaces traditional manual suturing. The principle of the stapler is similar to that of a stapler, that is, many small titanium nails are arranged in two circles (or two rows) at a certain interval on a special device. After being stimulated, the two legs of the titanium nails close together, thereby connecting the two sections of the intestine. At the same time, there is a circle of small blades between the two circles of titanium nails, which can cut the mucosa between the two circles to complete the anastomosis.

[0003] However, the existing cutting stapler cannot independently control the anastomosis work, and the ineffective and rapid control of the anastomosis will reduce the anastomosis efficiency. At the same time, in order to achieve independent control of the anastomosis, the cutting and anastomosis functions cannot be operated synchronously, which will affect the stability of the cutting and anastomosis. To this end, we provide a linear cutting stapler to solve the above problems. Utility Model Content
