The operating principle of the disposable open-loop minimally invasive anorectal stapler (TST) is based on the theory of "anal cushion downward movement", combined with the theory of "varices" into hemorrhoids, absorbed modern hemorrhoid treatment concepts, and combined with Chinese medicine The advantages of the ligation method have developed a new method that is more in line with the pathological characteristics of hemorrhoids and the needs of anal function. Compared with PPH, TST is a holistic surgical solution based on different hemorrhoids theories.
According to the number and size of the hemorrhoids, the operation of TST is to make a full purse or a half purse 2 to 3 cm above the dentate line, or "spot stitching", and simultaneously pull in the upper 1/3 of the hemorrhoids to remove the hemorrhoids The rectal mucosa and part of hemorrhoids are simultaneously "cut off", "suspended" and "reduced". Compared with PPH, TST is aimed at the number and size of different hemorrhoids, and there are more surgical methods.
TST is the continuation and extension of the minimally invasive method for hemorrhoids. In addition to preserving the advantages of PPH surgery with less trauma, less postoperative pain, quick recovery, postoperative complications and low recurrence rate, it also has the following advantages:
1. According to the number and size of hemorrhoids, the resection range of the hemorrhoid mucosa can be adjusted to achieve a good suspension effect.
2. Controllable removal of part of the hemorrhoid top tissue, reducing the arteriovenous blood flow in the anal cushion, and achieving the effect of reducing the volume.
Compared with PPH, TST is to maximize the preservation of normal mucosal bridges, maintain the fine sensation and contraction function of the anus, and further development of the minimally invasive treatment of hemorrhoids. As a unique technological innovation, TST currently holds 10 international and domestic patents.
In terms of medical equipment, domestic products have always been inferior to imports, and high-quality medical products with independent intellectual property rights are even rarer. Although TST was developed on the basis of PPH, it surpassed the realm of PPH in terms of academic theory and product quality, and reached a new level of hemorrhoid treatment. Seeing the high-quality domestic TST going to the world, as a Chinese doctor, I am very proud!
Since May 2011, I have performed nearly 20 TST operations. The results of the operation are comparable to those of PPH, but the side effects are significantly less than that of PPH, and the minimally invasive effect is more obvious. However, because the price is more expensive than PPH, it is difficult to generalize.
