Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical device, and more particularly to a vacuum suction type acne treater. BACKGROUND OF THE INVENTION Acne is a venous mass formed by venous plexus, dilatation, and flexion under the submucosal and anal canal skin of the lower rectum. It is the most common anorectal disease, mainly manifested by blood in the stool, sputum sputum, pain and itching. It can gradually develop into a prolapsed ring-shaped sputum, often with blood, erosion, infection, etc., which seriously affects the quality of life of patients. Acne can occur at any age, and the incidence increases with age. Traditional Chinese medicine has the saying that "ten men and nine women, ten women and ten women".

The usual treatments for acne include oiling and suppository in the anus, topical medication, topical physiotherapy, injection therapy, apron ligation, surgical resection, anal sphincter therapy, and the like. However, some of these treatment methods only serve as a temporary treatment, although the symptoms of discomfort can be alleviated, but the curative effect is not certain, and the recurrence rate is high.

Acne ligation is a common method for treating acne. It has a good effect on general acne, but the current clinical implementation of acne ligation is usually performed by the operator in the case of local or other anesthesia. It is not only time-consuming and laborious, but also easy. Causes bleeding and pain. In the case of emergency surgery for hemorrhagic hemorrhage, it is also necessary to complete under lumbar anesthesia or general anesthesia, which significantly increases the degree of trauma. In order to alleviate the pain of patients and the difficulty of surgery, many improvements have been added, such as a vacuum suction ligation method, which consists of a vacuum suction head, a negative pressure generator, and a coupling tube.

The therapeutic device was used in clinical trials of 120 patients with internal hemorrhoids. The results are as follows:

120 patients with internal hemorrhoids were randomly divided into a ligation group (n=60) and a control group (n=60).

There were 46 males and 12 females in the ligation group. The youngest is 22 years old, the largest is 55 years old, and the average age is 38.6 years old. Among them, 49 cases were simple internal hemorrhoids and 11 cases were mixed hemorrhoids. The ligation group was all treated with this therapeutic device. Methods The patient took the thoracic knee position, performed an anoscope, opened the light source, and after clearing the position of the internal hemorrhoid, the hypothetical suction head of the therapeutic device was aimed at the nucleus under direct vision, and then the therapeutic trigger was pulled to inhale the nucleus into the vacuum suction. In the head, at the same time, the suction head pushes the rubber band completely to the root of the nucleus.

In the control group, there were 52 males and 8 females. The youngest is 25 years old, the largest is 60 years old, and the average age is 43.3 years old. Among them, 42 cases were simple internal hemorrhoids and 18 cases were mixed hemorrhoids. The control group was all routinely treated, mainly using 1:5000 potassium permanganate hot water bath, twice a day, after the bath, local application of Ma Yinglong hemorrhoids cream. All subjects underwent an outpatient review 3 days, 6 days, and 9 days after treatment to observe the effect.

All count data was tested for X2 significance using Microsoft Excel (Office 2000). P>0.05: There was no significant difference in efficacy; PO.05: The difference in efficacy was significant; PO.01: The difference in efficacy was very significant.
