Description

Anoscope subassembly with cold light illumination

Technical Field

The utility model belongs to the anoscope field especially relates to an anoscope subassembly with cold light illumination.

Background

Anoscopes usually comprise a barrel or cone, i.e. a speculum, which can be held by an operator by means of a handle and can be introduced through the anus into the end section of the patient's rectum. In the aforementioned speculum which is hollow and open at two opposite ends, a dilator is inserted which is longer than the speculum, is cylindrical, has a substantially rounded end and is provided with a smooth surface. When the dilator is positioned in the speculum and the speculum is inserted into the rectum, the dilator functions to expand the muscle wall of the rectum without damaging the mucosa of the muscle wall. After insertion of the anoscope, the dilator is removed and the speculum is left in place. In this way, the lumen of the end segment of the rectum is temporarily dilated, thus enabling the easy introduction of other instruments and the performance of diagnostic and/or surgical procedures. For example, CN107949417A entitled anoscope capable of rotating discloses an anoscope which can be disassembled and provided with a window, but the anoscope cannot carefully look at the intestinal wall after being inserted into the intestinal tract. For example, patent No. CN105078401A discloses an anoscope with LED, etc., which is mounted in a handle slot, and has a limited irradiation range and weak irradiation effect.
