Description
Technical Field
The invention relates to an endoscopic anastomat for excision, in particular to an endoscopic anastomat for hemorrhoid circumcision, belonging to the technical field of medical equipment.
Background
Hemorrhoids are commonly called hemorrhoids as common diseases at the anus part, the hemorrhoids can be attacked at any age, but the incidence rate is gradually increased along with the age, the hemorrhoids are the most common anorectal diseases in China, and the induction factors of the hemorrhoids are many, wherein constipation, long-term drinking, eating of a large amount of irritant food and long-time sitting and standing are main induction factors, the hemorrhoids are divided into internal hemorrhoids, external hemorrhoids and mixed hemorrhoids according to different occurrence parts, a saw-toothed visible line is called an anal canal dentate line at the joint of the anal canal skin and the rectal mucosa, the internal hemorrhoids above the dentate line are the supporting structure of the anal pad, venous plexus and arteriovenous anastomosis support are pathologically changed or displaced to be covered on the rectal mucosa, and the anal pad is divided into a left side, a right front side and a right back side by a Y-shaped groove due to the contraction of internal sphincter muscles, so the internal hemorrhoids are usually found at the left side, the right front side and the right back side; external hemorrhoid below dentate line, which is covered by anal canal mucosa, and can be divided into connective tissue external hemorrhoid, varicose external hemorrhoid, and thrombosed external hemorrhoid; the mixed hemorrhoid is a mixed hemorrhoid which combines an internal hemorrhoid and an external hemorrhoid, the internal hemorrhoid is fused with the corresponding external hemorrhoid through a venous plexus, namely the upper venous plexus and the lower venous plexus are anastomosed, the mixed hemorrhoid is pulled out of the anus and is in a plum blossom shape, the mixed hemorrhoid is called as an annular hemorrhoid, and if the mixed hemorrhoid is incarcerated by a sphincter, an incarceration hemorrhoid is formed;
hemorrhoids are relatively ubiquitous in life of people at present, and bring much trouble to people in both life and health aspects, so the hemorrhoids become a problem of more concern, the hemorrhoids are difficult to treat after long-term use, a series of secondary hazards and diseases are generated, wherein the anal fissure is the most prevalent, patients with serious hemorrhoids can cause or induce cardiovascular and cerebrovascular diseases, particularly elderly patients, such as patients suffering from the psychological stress caused by the hemorrhoids, dare not go to a toilet, and aggravate constipation after long term use, and when defecation is difficult, the patients can hold breath forcefully, so that the heartbeat is accelerated to cause cerebral vessel rupture, and cerebral hemorrhage or cerebral embolism are caused; pain can also induce angina attack if internal hemorrhoid incarceration occurs; if thrombosis exists, pulmonary embolism can be caused, and the hemorrhoid is a disease with relatively high harm, so that the hemorrhoid treatment and prevention are very important for the timely treatment and prevention of the hemorrhoid;
in the course of treatment of haemorrhoids, operative treatment is the more effective treatment means among them, in the operation of treatment haemorrhoids, need use the anastomat, the current anastomat adopts adjusting nut to rotate behind many to close, because the direction of rotation represents advancing and retreating direction, therefore can cause certain direction of rotation mistake and lead to the mistake of advancing and retreating direction.
Therefore, there is a need for an improved stapler to solve the above existing problems.
