Embodiment Construction

[0021] Depend on figure 1 and figure 2 It can be seen that the disposable anoscope of the present invention includes an inner cylinder 2 and an outer cylinder 1, the inner cylinder 2 is a cylinder with a longitudinal strip opening on the side wall, and its cross section is C-shaped; the outer cylinder 1 is also The side wall is provided with a cylindrical body with longitudinal strip-shaped openings, and its cross section is also C-shaped. The opening arc of the C-shaped cross section of the inner cylinder 2 and the outer cylinder 1 ranges from 130° to 150°, and the opening arc of the C-shaped cross section of the inner cylinder 2 and the outer cylinder 1 remains the same. The outer wall of the rear end of the inner cylinder 2 is provided with a protrusion 4, the rear end of the outer cylinder 1 is provided with a locking ring 3 along the edge of the outer wall, and several locking grooves are formed along the circumferential surface of the locking ring 3. The edge of the i...

Abstract

The invention discloses a disposable anoscope which is used for various disease checks of the lower sections of the anal canal and the rectum and provides a space for operation treatment. The disposable anoscope comprises an inner cylinder and an outer cylinder, wherein the inner cylinder is a cylinder of which the side wall is provided with a longitudinal strip opening, and the cross section of the inner cylinder is in a C shape; the outer cylinder is also a cylinder of which the side wall is provided with a longitudinal strip opening, and the cross section of the outer cylinder is also in aC shape; and the inner cylinder is mutually sleeved with the outer cylinder to form a structure that the inner cylinder can rotate along the inner wall of the outer wall. When the inner cylinder rotates to lead the openings of the inner cylinder and the outer cylinder to superpose, a check window through which direct observe can be performed is formed, and the size of the check window can be adjusted and controlled according to the requirement, thereby the observation visual field range is wide and controllable. When the openings of the inner cylinder and the outer cylinder are completely closed, the anoscope can be conveniently inserted into the anus. The disposable anoscope solves the problems of inconvenient clinical check and difficult treatment operation of the currently used anoscope.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable anoscope used for checking various lesions in the anal canal and lower rectum and providing space for surgical treatment. Background technique [0002] At present, to check the abnormality of the anal canal and the lower rectum wall clinically, an anoscope is generally used to observe gradually from the internal opening during the withdrawal process after being inserted into the anus. The currently used anoscope has a single-tube structure. Since the anoscope with a single-tube structure can only be observed from the inner opening, the observation field of view is narrow, and the observed tissue shrinkage and intestinal contents may cover the intestinal wall. The limitations cause limited observation, which greatly affects the accuracy and speed of clinical diagnosis. At the same time, because the space available for operation and observation is too narrow, it is difficult to car...
