Auxiliary devices for anorectal examination and treatment

technical field

The utility model relates to a surgical instrument, in particular to an auxiliary instrument for anorectal examination and treatment, which belongs to the technical field of medical instruments.

Background technique

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 the abundant venous plexus in the lower rectum or anal canal. If they expand or varicose in one or several places, they become hemorrhoids. caused by vascular disease. Since the 1970s, breakthroughs have been made in the study of hemorrhoids, and the discoveries of anatomy, histology and physiology have given modern concepts to hemorrhoids. In 1975, Thomson proposed for the first time that "hemorrhoids are normal anatomical structures that everyone has. They are labial warts or anal cushions at the lower end of the rectum. The pathological hypertrophy of anal cushions is hemorrhoids." This new The concept is supported by famous scholars such as Alexander-Williams (1982), Bernstein (1983) and Melzier (1984). The new concept of hemorrhoids has been widely adopted in the newly published monographs of anorectal diseases abroad, and it has been gradually recognized in the field of anorectal surgery in my country in the past 10 years.

The traditional methods of internal hemorrhoid treatment, including sclerosing agent injection, rubber band ligation and various forms of surgical resection, etc., are all aimed at the treatment of the hemorrhoid itself, aiming at shrinking or disappearing the hemorrhoid. Among the surgical procedures for hemorrhoidectomy, there is a method called PPH surgery, which is suprahemorrhoidal circumcision with the help of a round tubular stapling instrument. The principle is: while retaining the anal cushion tissue, the internal hemorrhoid and the hemorrhoidal mucosa and submucosal tissue are resected circularly for about 3 to 4 cm, and the two ends are anastomosed at the same time. The purpose of suspension fixation is to restore the pathological anorectum to its normal anatomical state.

Using PPH surgery to treat severe hemorrhoids has the advantages of relieving postoperative pain, reducing postoperative bleeding, shortening hospital stay, speeding up the recovery cycle, not affecting daily life, and low recurrence rate. Almost no pain is felt. Since the operation solves the root cause of hemorrhoids, the short-term and long-term effects are ideal. For some hemorrhoids that are very difficult to treat with traditional therapy, such as mixed hemorrhoids, annular hemorrhoids, severe hemorrhoid prolapse, anal prolapse, etc., PPH surgery also has a unique curative effect.

However, clinical application has found that in some patients, lesions do not occur in three hemorrhoids at the same time, but in one or two hemorrhoids. All will be removed at one time. Obviously, this operation will cause unnecessary damage to the patient and has no positive effect on postoperative recovery.
