摘要：
A linear surgical stitching device comprising: an upper forceps tine, a lower forceps tine, and a staple chamber assembly (1) disposed on the lower forceps tine. Said staple chamber assembly comprises a cutting groove. Disposed inside of the cutting groove is a cutting knife (8) that moves back and forth along the axis of the cutting groove. Said cutting knife comprises a blade (11) disposed at the far end of the cutting knife and a cutting knife bottom surface (10). Disposed inside of said staple chamber assembly are a sliding block (4) and a spring position block element. Arranged at the far end of the bottom of the staple chamber assembly is a housing space for housing said sliding block. Said staple chamber assembly has an initial state and a firing state. When said staple chamber assembly is in the initial state, said sliding block is on top of the spring position block element and applies a force restricting the top of said spring position block element to be above the plane of the cutting knife bottom surface, and the near end of the sliding block connects with the far end of the cutting knife. When said staple chamber assembly is in the firing complete state, said sliding block remains at the far end of the staple chamber assembly so that the top of said spring position block element is above the cutting knife bottom surface and comes into contact with the far end of the cutting knife, thereby preventing the cutting knife from sliding toward the far end of the staple chamber assembly. The present application provides the advantage of simple structure, and prevents misfiring throughout the whole operation from the completion of a firing to the exchange of a new staple chamber, thereby eliminating the possibility of misfiring after a first firing and providing more safety.L'invention concerne un dispositif de suture chirurgicale linéaire comprenant: une dent de pince supérieure, une dent de pince inférieure, et un logement d'agrafes disposé sur la dent de pinc
