Hemorrhoids surgical instrument

Abstract

The invention relates to a surgical operation instrument for the treatment of hemorrhoids. The invention includes a ring group and a traction component, the ring group is constituted by two ring bodies, and the ring body is divided into an upper ring body and a lower ring body, the diameters of the upper ring body and the lower ring body are different or same, the ring bodies are respectively arranged on the traction component, the upper ring body or the lower ring body realizes the up and down movements by a movable part which is arranged in the traction component. The hemorrhoids can be firmly clamped in the metal ring group by using the ring group which can be nested mutually, the blood supply is blocked, thus hemorrhoids is narrowed gradually, shed off and finally discharged to the outside of the body along with the metal rings, the invention has no side effects and can be restored to the normal tissue status after healing. The operation time is very short, the operation is simpleand easy, the invention can not have the evil consequences of great bleeding, anal fistula and operation failure caused by damage of the anastomosis ring once a nail is not formed well or during the withdrawal process of a nail anvil, and the invention can also avoid the shortcoming that the anastomosis ring is left in the body for a long time to have the anal canal stenosis.

Description

technical field [0001] The invention and a surgical instrument, in particular a surgical instrument for treating hemorrhoids, belong to the technical field of medical instruments. Background technique [0002] People have a history of more than 4,000 years in the understanding of hemorrhoids, and there have been endless theories about hemorrhoids for a long time. Since the 18th century, hemorrhoids were considered to be rich venous plexuses in the lower rectum or anal canal. If they expand or varicose in one or several places, they become hemorrhoids, that is, hemorrhoids are protruding veins, which are caused by various reasons. Vascular disease. Since the 1970s, breakthroughs have been made in the study of hemorrhoids, and many modern concepts have been given to hemorrhoids by anatomy, histology and physiology. In 1975, Thomson proposed for the first time that "hemorrhoids are normal anatomical structures that everyone has. The lip-shaped warts at the lower end of the re...

Problems solved by technology

However, the performance of this kind of device is not stable at present, and the operation process is complicated, which requires a high level of doctors, and it is difficult for doctors to master it. Once the nail is not well formed or the anastomotic ring is damaged during the process of withdrawing from the anvil, a large amount of bleeding will occur, forming anal fistula , making the operation fail

Even if the anastomotic ring is normal and qualified after the operation, because the anastomotic ring is rigid and non-deformable, it will stay inside the anal canal for a long time, which will cause anal canal stenosis and affect the patient's physiological function to a certain extent
