Anastomat with mistaken triggering prevention safety mechanism

Abstract

The invention discloses an anastomat with a mistaken triggering prevention safety mechanism, and belongs to the technical field of medical instruments. The anastomat is characterized by comprising a fixed box, the left side of the fixed box is fixedly connected with a nail bin seat, the top of the fixed box is provided with a connecting cover, the left side of the connecting cover is fixedly connected with a nail abutting seat, and the nail abutting seat is fixedly connected with the connecting cover. A sliding bin is formed in the fixed box from left to right. Through arrangement of a second rack, when a medical worker presses the second rack, a first rack can be rapidly rotated through the second rack, after the first rack is separated from a first gear, a worker can normally rotate a rotating handle, and a first spring is matched for use; after the medical staff loosens the second rack, the first spring can quickly drive the second rack to move outwards without manually resetting the second rack by the staff, so the second rack quickly reversely rotates the first rack through the second gear, the first gear is firmly fixed, and a good limiting effect is further achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, to a stapler with an anti-misfire safety mechanism. Background technique [0002] The stapler is the first stapler in the world. It has been used for gastrointestinal anastomosis for nearly a century. It was not until 1978 that the tubular stapler was widely used in gastrointestinal surgery. It is generally divided into one-time or multiple-use staplers, imported or domestic staplers. It is a device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of production technology, the clinically used stapler is reliable in quality, easy to use, tight and suitable, especially its fast suturing, easy operation and There are few side effects and surgical complications, and it also enables tumor resection that was unresectable in the past.

Problems solved by technology

[0003] After searching, the Chinese patent discloses a linear cutting stapler (publication number is CN103126735A). This patented technology changes the traditional push-type firing principle, changes the rotating force into a driving force, and makes the firing force stable, thereby greatly reducing It meets the requirements of the user, improves the accuracy of firing, greatly reduces the risk of surgery during the operation, and improves the safety of the entire operation. However, the limit attachment in this patent is only the rotating handle After reaching the designated position, the limit attachment can limit the rotation handle, which reduces the practicability of the limit attachment, thereby increasing the risk of surgery
