Description
This utility model relates to the sufferer new therapy that combines both Chinese and Western medical practices of anorectal section--the essential small-sized medical instrument of Barron ligation.
Barron ligation treatment anorectal section sufferer is the new therapy that developed recently gets up.But this therapy is popularized as yet.So be applicable to that the medical apparatus and instruments of Barron ligation--looping and binding device also only is in the junior stage, so the existing looping and binding device that uses also has only function singleness, second-rate four to five kinds of models.
In the popular product of existing market, comparatively advanced is AXT-2 type (82 type) looping and binding device that colliery, Chongqing peace instrument factory produces.Though this looping and binding device is airtight at piston, the piston resistance, dust collecter is interchangeable and aspect such as appearance and modeling is better than other products, and still there is following defective in the actual back proof of using:
1. though this product has taked piston life to prolong measure, promptly airtight quality is kept measure, and the airtight durability period of piston is still shorter, and it still will regularly add vaseline sealant and frequent the adjustment.Therefore keep the comparatively tired lock of airtight quality;

5.AXT-2 the pushing sleeve mechanism structure complicated, technology difficulty is bigger, so manufacturing cost is higher;
6. existing whole looping and binding devices all do not have cover and prick depth indicating device.Though the AXT-2 type has form can observe the suction depth, be easy in the treatment be observed unclear by assorted body pollution visor such as body fluid feces.So mostly the doctor is to estimate by rule of thumb suction and talks shallow the operation that it is inaccurate finally to cause cover to be pricked.This shows that this is the key factor of quality of medical care.
