Embodiment 1

[0040] A rectal dilator, the rectal dilator includes an anal expansion ring 1, a movable sleeve 2 that can be inserted into the anal expansion ring, the movable sleeve can move forward, backward and rotate relative to the anal expansion ring, wherein the movable sleeve is close to The end is open and the distal end is closed. There is a window area 3 on the side wall near the far end of the sleeve. The body section of the window area is C-shaped. The lip provides a stop to prevent over-insertion of the cannula into the rectum.

[0041] For the convenience of observation, the cannula of the rectal dilator is transparent or translucent, or both the cannula and the anal expansion ring are transparent or translucent. The edges of all parts, especially the edges of the parts inserted into the anus and rectum, should preferably be kept smooth to prevent tissue scratches.

Embodiment 2

[0043] A rectal dilator, the rectal dilator includes an anal expansion ring 1, a movable sleeve 2 that can be inserted into the anal expansion ring, the movable sleeve can move forward, backward and rotate relative to the anal expansion ring, wherein the movable sleeve is close to The end is open and the distal end is closed. There is a window area 3 on the side wall near the distal end of the casing. 2 to 1 / 3, the angle of the notch in the window area 3 is 30°≤θ≤150°, preferably 60°≤θ≤120°, and the proximal end of the sleeve 2 is provided with a lip 4 . The lip provides a stop to prevent over-insertion of the cannula into the rectum.

[0044] For the convenience of observation, the cannula of the rectal dilator is transparent or translucent, or both the cannula and the anal expansion ring are transparent or translucent. The edges of all parts, especially the edges of the parts inserted into the anus and rectum, should preferably be kept smooth to prevent tissue scratches.

Embodiment 3

[0046] A rectal dilator, the rectal dilator includes an anal expansion ring 1, a movable sleeve 2 that can be inserted into the anal expansion ring, the movable sleeve can move forward, backward and rotate relative to the anal expansion ring, wherein the movable sleeve is close to The end is open and the distal end is closed, and the closed end is round and smooth, showing a cone-shaped, hemispherical, or bullet-shaped arc top; there is a window area 3 on the side wall near the distal end of the casing, and the section of the tube body in the window area is C Type, wherein the long axis of the window area is parallel to the long axis of the pipe body, the length of the window area is 1 / 2 to 1 / 3 of the length of the pipe body, and the angle of the notch of the window area is 30°≤θ≤150°, preferably 60°≤θ≤120° , The proximal end of the sleeve 2 is provided with a lip 4 . The lip provides a stop to prevent over-insertion of the cannula into the rectum.

Abstract

The invention belongs to the field of medical instruments and discloses a rectum dilator. The rectum dilator comprises an anus expansion ring and a movable casing, wherein the movable casing can be inserted into the anus expansion ring; the movable casing and the anus expansion ring can carry out opposite advancing and retreating and rotational motion; the near end of the movable casing is open and the far end is closed; a window region is formed in the side wall, close to the far end, of the casing; and a labial margin is arranged at the near end of the casing. The rectum dilator is simple in structure, diverse in function, easy to operate and low in cost, and can be operated by a single person; and medical workers for walking equipment are liberated.

Description

technical field [0001] The invention belongs to the field of medical instruments and relates to a rectal dilator. Background technique [0002] During rectal examination and rectal surgery, it is necessary to keep the rectum in an expanded state for observation and operation. There are many types of rectal dilators disclosed in the literature, and there are roughly three types: one is a tubular structure, based on a tubular object inserted into the rectum; The other is the clamp structure, which is based on a clamp-like structure inserted into the rectum; the other is the expandable structure, which is characterized by balloons or expandable stents. A tubular structure such as CN203154573U (201320198755.8) discloses a rectal dilator, which is a circular hollow tube with a vent hole with a handle. Surgery; CN101237810A (200580051277.6) discloses a rectal insertion type surgical system, including a cannula device, a shield, anal expansion ring, and a window area. The working...
