Minimally invasive PPH technology makes hemorrhoid patients worry-free PPH technology is also known as “hemorrhoidal mucosal circumcision”, which is a new technology based on the new understanding of the pathogenesis of hemorrhoids caused by anal cushion lesion lesions.PPH surgery is a special instrument known as “PPH anastomosis” to make a circular excision of the prolapsed band of rectal mucosa above the hemorrhoids. PPH surgery is to use a special instrument called “PPH anastomosis” to make a circular excision of the prolapsed band of rectal mucosa above the hemorrhoids. During the surgery, the anus is first dilated, and the rectal mucosa is looped and sutured at about 4 cm above the dentate line (the junction line between the rectum and the anal canal), and then the PPH anastomosis is inserted into the anus, and the anastomosis removes the prolapsed band of mucous membranes, and the whole process takes only about half an hour. Because the rectal mucosa above the dentate line is innervated by visceral nerves, the patient has almost no pain after the surgery; and because the surgery not only removes the prolapsed band of rectal mucosa, but also blocks the terminal anastomotic branch of the rectal terminal artery, eliminating the root cause of hemorrhoids, it has a very desirable therapeutic effect on the internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, cyclic hemorrhoids, severe hemorrhoids prolapses, prolapsed anus, and so on. It is characterized by quick effect, quick recovery and no pain after surgery. Scope of application Single-use anal hemorrhoid anastomosis is suitable for rectal mucosal prolapse or hemorrhoidal tissue stapling repair in the anal canal, for the treatment of III, IV degree internal hemorrhoids. Technical advantages 1, safety: no need to remove the anal cushion, the maximum degree of preservation of the normal function of the anus, to avoid anal stenosis, anal incontinence and other complications. 2, painless: the prolapse of the anal hemorrhoids back to the original position, at the same time, cut off to the hemorrhoids to provide blood to the blood vessels, do not damage the perianal skin, so almost no pain after the operation. 3.Small trauma, fast recovery: anastomosis annular excision of mucous membrane for the non-open wound, less bleeding, eliminating the postoperative change of medicine trouble, can quickly return to normal life. 4.Diagnosis and treatment scope: annular hemorrhoids, multi-flap hemorrhoids, huge isolated hemorrhoids, internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, annular hemorrhoids, incarcerated hemorrhoids, rectal mucosal prolapse, prolapse of the anus and so on. 5, suitable for the object: due to less damage, especially suitable for middle-aged and elderly people, white-collar people who pay attention to efficiency and traditional treatment of recurrence, accompanied by mild prolapse of anus and rectal mucosal prolapse of patients. Contraindications It is not recommended for pregnant women, children, those with persistent constipation, pelvic tumors, portal hypertension, Bunyika syndrome or those who cannot tolerate surgery. Surgical mechanism The traditional methods of internal hemorrhoid treatment, including sclerotherapy, rubber band ligation and various forms of surgical excision, are all aimed at treating the hemorrhoids themselves, with the aim of shrinking or disappearing the hemorrhoid nuclei. Anastomotic circumferential hemorrhoidectomy is completely different from traditional methods in terms of treatment theory, avoiding damage to the perianal skin causing postoperative pain on the one hand, and preserving the integrity of the anal cushion on the other hand, avoiding postoperative fine bowel control disorders. The mechanism of PPH surgery is to excise the mucosa and submucosal tissue of the lower rectal wall in the upper part of the prolapsed hemorrhoid near the upper edge of the hemorrhoid, and anastomose the mucosa of the distal and proximal ends at the same time, so that the prolapsed hemorrhoid and the mucosa will be suspended and pulled upward, and will no longer be prolapsed. At the same time, because the artery from the superior rectal artery supplying hemorrhoids located in the submucosal layer is cut off, the blood supply of hemorrhoids is reduced after the operation. Therefore, the exact name of the procedure should be: Hemorrhoidal epimucosal and submucosal circumcision, anal cushion suspension. The mechanism of the product is characterized by a single-use anal hemorrhoidal anastomosis, which is a PPH surgical instrument. the mechanism of the PPH surgical method is to excise the mucous membrane and submucosal tissues of the lower rectal wall circumferentially above the prolapsed hemorrhoids near the upper edge of the hemorrhoids and anastomose the mucous membranes of the distal and proximal ends of the hemorrhoids at the same time of excision to make the prolapsed hemorrhoids and the mucous membranes to be suspended upwards and pulled, and no longer prolapsed. At the same time, due to the submucosal layer located in the upper rectal artery from the supply of hemorrhoids artery is cut off, postoperative hemorrhoid blood supply is reduced, tends to become smaller to retain the anal cushion with fine discrimination ability of the anal cushion tissues, to restore the normal anatomical structure of the lower end of the rectum, postoperative patient trauma is small, pain is light, recovery is fast, and fewer complications. Structural features of the product In order to facilitate the suturing of the purse strings, the staple holder assembly and the anastomosis body are designed to be separated from each other in the form of a structure, and then the two are docked during anastomosis, which is easy to operate. PPH surgery precautions The treatment mechanism of PPH is to excise a section of mucosa above the hemorrhoidal nucleus in a circular motion, and at the same time anastomose the mucosa of the rectum near and far, so that the prolapsed anal cushion tissues can be lifted up, and because of the excision and anastomosis of the mucosa at the same time, it also blocks part of the blood supply, so that the blood vessels of the anal cushion which have been excessively proliferating and expanding can be partly atrophied due to the reduction of the blood supply, so that the aim of preventing its prolapse can be achieved. Its best indications should be the third stage of internal hemorrhoids, annular mixed hemorrhoids, and concomitant low rectal mucosal prolapse are also indications. As a new treatment method, because there is no damage to the anal cushion area tissue, does not affect its reflex to defecation, the anal cushion to the anus closure of the pressurizing effect is also not affected, so theoretically speaking, this treatment is in line with modern hemorrhoid treatment principles. From the results of our surgery, the recent efficacy is good.
