Abstract

The invention relates to the technical field of anastomats, and particularly relates to an anastomat with an adjustable bending angle of a bending mechanism. The anastomat comprises a fixed handle, a connecting sleeve, a rod body, a nail bin seat, a nail abutting seat and a movable handle, wherein a connecting rod mechanism is arranged in the fixed handle and comprises a guide rod, a push rod and a center rod; a first bending pipe is arranged in the middle of the rod body; a second bending pipe is arranged on the center rod; a third bending pipe is arranged on the push rod; an abutting seat is arranged in the fixed handle; a buffer mechanism is arranged on the abutting seat and comprises a pressure seat and a movable column; the movable column is sleeved with the pressure seat; a pressure bin is arranged in the pressure seat; and a piston is arranged at the bottom end of the movable column. The anastomat is provided with the buffer mechanism, the force during pinching and combination of the movable handle can be buffered, the phenomenon that the nail bin seat and the nail abutting seat are deformed due to too large force and accordingly cutting and suturing of wound parts are affected is avoided, and the operation stability of the anastomat and the surgical cutting and suturing accuracy are improved.

Description

technical field [0001] The invention relates to a stapler, in particular to a stapler with an adjustable bending angle of a turning mechanism, and belongs to the technical field of staplers. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. The main working principle is to use titanium nails to separate or anastomose tissues. It is similar to a stapler. According to different scopes of application, it can be divided into skin staplers, digestive tract circular Shaped stapler, rectal stapler, circular hemorrhoid stapler, circumcision stapler, blood vessel stapler, hernia stapler, lung cutting stapler, etc., the stapler is the world's first stapler, used for gastrointestinal anastomosis For nearly a century, tubular staplers were not widely used in gastrointestinal surgery until 1978, generally divided into one-time or multiple-use staplers, imported or domestic staplers, which are used in medicine to replace traditional manual sutu...
