Abstract

The invention relates to an anastomat and a state indicator. The state indicator comprises a closed pull plate, a triggering pull plate, a closed connecting block, a triggering connecting block, a closed pointer, a triggering closed pointer and an indicator panel, wherein the closed connecting block and the triggering connecting block respectively consist of a rotating shaft and a driving shaft; the upper end of the rotating shaft is fixed with the closed pointer and the triggering closed pointer respectively, which can rotate with the rotating shaft on the same axis; and the closed pull plate is provided with a spring mounting structure and a sliding connection groove of a driving device, and is in rotary connection with the driving shaft of the closed connecting block; the triggering pull plate is provided with a spring mounting structure and a pushing device sliding connection groove, and is in rotary connection with the driving shaft of the triggering connecting block. The driving screw of the driving device of the anastomat is connected with the sliding connection groove of the driving device; and the pushing device is connected with the sliding connection groove of the pushing device. The state indicator can indicate the closed state and the triggered state of the anastomat respectively, and has a transitional area. And the indicator is easy for observation, thereby reducing risks in operation and ensuring that the operation can finish smoothly.

Description

technical field [0001] The invention relates to a surgical medical instrument, in particular to a stapler and a state indicating device thereof. Background technique [0002] In surgical operations, medical staplers have become an indispensable auxiliary medical device in the process of suturing human tissue. Among them, the circular stapler is used for end-to-end, end-to-side, and side-to-side anastomosis in digestive tract lumen surgery. It provides two rows of annular staples spaced from each other. Shaped anastomosis. The application of medical stapler has many advantages such as less blood loss during operation, shorter operation time, reduction of manual operation error, avoidance of infection, and quick recovery of postoperative function. [0003] One of the existing indicating devices for staplers is to process an indicating plate on the driving screw as a pointer, and two different color blocks are set on the pointer to indicate different closed states. When the ...
