Description

Medical expander

Technical Field

The utility model relates to the technical field of dilators, in particular to a medical dilator.

Background

Hemorrhoids are a common anorectal disease including internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. For severe internal hemorrhoids, surgical treatment is often performed by ligation, i.e. by blocking the blood supply to the base of the hemorrhoid by ligating it, which causes anoxic necrosis of the hemorrhoid. The hemorrhoid is removed and the wound surface basal part is repaired simultaneously, and when the hemorrhoid is removed, new granulation tissues rapidly fill the wound surface to achieve the cure purpose. When performing examination, diagnosis or operation on internal hemorrhoid, external hemorrhoid and anal flesh, the anus is required to be opened, and then other surgical instruments for examination or treatment are put in the anus, however, because the anus is required to be opened by the aid of the special anus position, especially for patients with obesity, the special anus position is inconvenient, so that a dilator is required, which can help doctors to observe the internal condition and perform operations such as examination and operation.

The Chinese patent publication CN214415411U discloses a medical dilator, which aims to prevent lubricant on the surface of the dilator from sliding by hands of doctors during the expansion, thereby influencing the expansion. The principle of the anti-slip device is that an anti-slip sleeve is arranged on the surface of the expander, so that the hand slip is avoided, a fixing plate, a limiting hole and a limiting rod are further arranged, after the expander is pinched, the expander is opened, the fixing rod penetrates through the limiting hole on the fixing plate to fix the positions of the two handles, so that the expander cannot be opened, the opened fixer is fixed, and a doctor can more conveniently treat diseases such as hemorrhoids.

But current device is less and need rotate when inserting spacing hole and get into when using the gag lever post, need fix with the help of the screwdriver, so fixed mode is inconvenient inadequately, has increased the operation time, causes the discomfort for the patient. Therefore, a dilator with a more convenient fixed handle is designed for solving the problems.
