Problems solved by technology

[0003] The publication number is CN209404857U, which provides a disposable linear stapler. The executive mechanism of the device, that is, the suture mechanism, mainly drives the push plate and the nail push piece to move forward through the firing handle, and the nail push piece cooperates with the staple cartridge to move the staple cartridge The staples inside are pushed toward the anvil until the staples are formed on the anvil. This suture mechanism is simple in structure and has the following disadvantages: 1. The distance between the staple cartridge and the anvil cannot be adjusted according to the tissue to be sutured. The thickness of the nail can be adjusted freely, so that the staple cartr

Abstract

The invention provides a suturing assembly of an anastomat and the anastomat. The suturing assembly of the anastomat comprises an installation base, a nail anvil base, a nail anvil assembly, a shell, a nail pushing assembly, a nail bin, a telescopic bin, a support assembly, a push rod, a screw assembly, a limiting assembly, a reset spring, an isolation assembly and a fixing screw. According to the invention, the relative positions of the telescopic bin and the push rod are adjusted, and the telescopic bin and the push rod are fixed together through the screw assembly; after the distance is changed, the push rod is not influenced to push the nail pushing assembly; the distance between the nail anvil assembly and the nail bin can be adjusted according to the thickness of tissue to be sutured in use, so that the moving distance of the nail bin is relatively short in suturing, and the deviation of the position of the nail bin in suturing is prevented; when the nail anvil assembly is not installed in place, an isolation block can be ejected to be blocked between the nail anvil assembly and the nail bin, so that the nail bin is prevented from making contact with the nail anvil base; and after the nail anvil assembly is installed, the isolation block is pressed downwards, and the movement of the nail bin cannot be hindered, so that the damage caused by misoperation due to no installation of the nail anvil base is avoided.

Description

technical field [0001] The invention relates to the technical field of medical suturing equipment, in particular to a suturing component of a stapler and a stapler. Background technique [0002] Stapler is a device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of manufacturing technology, the application range of stapler is more and more extensive in clinical practice. In surgery, the suturing principle of stapler is, The staples are driven into the tissues that have been aligned and need to be anastomosed together. After passing through the tissues, the staples are blocked by the anvils on the opposite side, and bend inward to form a "B" shape that is misaligned with each other. The staples are permanently stapled together. The staples are generally placed in the staple cartridge. The staple cartridge is installed in the suturing component of the stapler. The staple cartridge is pushed by the suturin...
