Description
Technical field
The utility model relates to a kind of medical instruments, and in particular to a kind of tissue folder of anti-offset.
Background technique
Tissue folder, also known as blood vessel clip, ligation clip, hemostatic clamp, in surgical operation (mainly minimally invasive laparoscopic surgery)
Folder closes blood vessel and pipeline tissue.Such as gall-bladder is closed for folder in cholecystitis, calculous cholecystitis, gallbladder polyps patient's cholecystectomy
Pipe and cystic artery play hemostasis, ligation closure function.The blood vessel of early stage or the common method of tissue ligation are that needlework coincide,
But needlework coincide the inevitable defects such as that there are blood vessel internal membrane damages is larger, anastomosis procedure is complicated, takes long time, therefore from blood
The trend that gradually substituted needlework coincide since pipe clamp comes out.Initial blood vessel clip based on metal material, as titanium folder, silver brain clip,
Stainless steel clamp etc., such blood vessel clip is although cheap, easy to use, but tends to occur loosening, vacillating, falling off too early
Phenomenon, and can the postoperative optical image diagnosis of interference effect in indwelling body；As thyrite good fortune company in 1999 releases Brunswick folder, no
Absorbable clips are opened up markets gradually, become the new selection mode of one kind of tissue ligation, and Brunswick folder is improved from structure design
Occur loosening, phenomena such as vacillating or falling off too early, in indwelling body can also will not the postoperative optical image diagnosis of interference effect, but it is long
Potential hazard can be still generated in phase indwelling body.Recently as the development of absorbable material, absorbable biological folder enters the market gradually, but
It is a variety of that there are still Pressure values is insufficient for current Absorbable clips, anti-slip power is insufficient, laparoscope clamp process is easy to happen offset etc.
Problem.
US7326223 discloses ligation clip (the LIGATING CLIP WITH INTEGRAL with integral cutting guide rail
CUTTING GUIDE), specifically disclosing hemostatic clamp is two arm configuration of V bifurcated, by safe catching lock, elastic hinge, arcuate nail leg
(clamp), integrated anti-slop serrations and five part of knuckle composition.But there are still some problems in use, is mainly manifested in securely
Property not enough, blood folder use process in will appear locking position slip, be easy to appear offset.
203776976 U of CN discloses a kind of hemostatic clamp of anti-dropout, specifically disclose including be arcuate structure
One clamp arm and the second clamp arm, using elastic hinge connection, free end is mutually matched buckle structure for one end of two clamp arm, is led to
Crossing one group is yin-yang fastening structure, the secure latch being mutually locked, to improve fastness.203776975 U of CN discloses one kind
Hemostatic clamp, the inner surface for specifically disclosing arcuate two-arm is that corresponding concaveconvex structure makes to be pressed from both sides to close blood vessel convenient for the engagement of two-arm
Or pipeline tissue can be firmly closed；By the taper rack gear of the convex on male and fomale(M&F), increasing coefficient of friction, anti-sliding is de-,
The effect of hemostasis and anti-leak can be better achieved.However, the effect of the hemostatic clamp practical application of above two anti-dropout has
Limit.
To sum up, the prior art still lacks a kind of anti-offset tissue folder for being able to satisfy absorbable material, can satisfy clinic
Demand.
