Stapler with adjustable bending angle of turning mechanism

Abstract

The present invention involves the field of anastomatics, which is specifically a condenser with a curved angle with adjustable turning mechanisms, including a fixed handle, connecting cover, pole body, nail warehouse seat, nail seat and activity handle, internal handle of the fixed handle, and the internal handle of the fixed handle.There are connecting rod mechanisms. The connecting rod mechanism includes a guide rod, push rod, and center pole. The middle part of the rod body is set with a first bending pipe, a second bending pipe is set on the center rod, and a third discount is set on the push rod.The curved pipe, the internal setting of the fixed handle is set to the seat, there is a buffer mechanism on the seat, the buffer mechanism includes the pressure seat and the activity column, the activity column is set inside the pressure seat, and the interior of the pressure seat has a pressure warehouse, the activity column is set up, the active columnThere is a piston at the bottom of the bottom.The present invention has a buffer mechanism that can buffer the intensity when the movement handle is pressed and merged to avoid excessive strength and cause deformation of the nail warehouse and the nail seat operation, which will affect the cutting and suture of the wound.Stability and surgical cutting suture accuracy.

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...

AI Technical Summary

Problems solved by technology

[0003] Existing staplers are directly pinched when pinching the handle, without a buffer protection function, resulting in the combination and deformation of the front-end staple magazine seat and the nail-resisting seat of the stapler during the pinching operation, which is prone to poor force control and is not suitable for surgical cutting and suturing Inaccuracies caused by the wound, which can affect the cutting and suturing operation of the surgical site
