Problems solved by technology

[0006] Disadvantages of the anoscope disclosed in WO2004 / 021874 include the fact that even when the dilator is not inserted in the mobile part, the ring and thus the operating window can also be turned
This means that after the surgical treatment of the area of ​​the rectal mucosa, and therefore during the step of protruding the aforementioned area of ​​the rectal mucosa through the operating window in the anoscope, if the ring and thus the operating window are accidental in the absence of the dilator If it is rotated, there is a real risk that the suture will be dragged by the operating window, thereby causing injury to the patient

Embodiment Construction

[0018] In this specification and the appended claims, the adjective "proximal" defines the part, section or end of the anoscope 1 which, in use, faces an operator (eg a surgeon) who is holding and / or using the anoscope. Thus, the adjective "distal" defines the part, section or end of the anoscope 1 which, in use, faces in the opposite direction from the direction of the operator holding and / or using the anoscope.

[0019] Figure 1 to Figure 5 An anoscope 1 comprising a fixed part 2 , a moving part 3 and a dilator 4 is shown. The fixed part 2, the moving part 3 and the dilator 4 are made of a sterilizable polymer material such as polypropylene, or other materials suitable for medical use.

[0020] The form fitting fixed part 2 and moving part 3 are open and hollow at opposite ends. When in use, that is, when the anoscope 1 is assembled ( Figure 5 ), the moving part 3 is received in the fixed part 2, and the dilator 4 can be selectively inserted into the moving part 3 or re...

Abstract

The anoscope (1) comprises: a fixed part (2), which is hollow and opened at two opposite ends; a moving part (3), which is hollow and opened at two opposite ends, and the moving part (3) is connected to the The fixed part (2) is form fit, and the moving part (3) is configured to rotate coaxially in the fixed part (2); the window (8), which is formed in the moving part (3) and configured to enable access to a portion of the rectal mucosa; a dilator (4) that can be selectively inserted into the long lumen (13) of the anoscope (1) or from the The long chamber (13) is taken out, said long chamber (13) included in said moving part (3). The anoscope (1) is characterized in that the anoscope (1) includes a positioning locking part (9), and the positioning locking part (9) is configured to be used when the dilator (4) is not inserted The long cavity (13) prevents the moving part (3) from rotating coaxially in the fixed part (2).

Description

technical field [0001] The invention relates to an anoscope which can be used in the field of proctology as a diagnostic or surgical instrument. Background technique [0002] Anoscopes of known type generally comprise a barrel or cone (a so-called "speculum") which can be held by the operator by means of a handle and which can be introduced (through the anus) into the distal section of the patient's rectum. In the aforementioned speculum, which is hollow and open at opposite ends, a dilator is inserted which is longer than the speculum, has a cylindrical shape, has substantially rounded ends, and is provided with a smooth surface. When the dilator is positioned within the speculum and the speculum is inserted into the rectum, the dilator acts to expand the muscular wall of the rectum without damaging the mucous membrane of the muscular wall. After insertion of the anoscope, the dilator is removed leaving the speculum in place. In this way, the lumen of the distal portion o...
