Measuring instrument for prolapse of rectum

Abstract

The invention discloses a measuring instrument for prolapse of rectum capable of carrying quantitative measurement on prolapse of rectum. The measuring instrument comprises a shell, an endoscope, a containing mechanism and a driving mechanism, wherein a far-end portion of the shell is provided with an outer tube; the containing mechanism comprises a plurality of containing cavity pieces, a near-end portion of each containing cavity piece is in rotatable connection to a far-end portion of the outer tube, and the containing cavity pieces are arranged along the peripheral direction of the outer tube to form a containing cavity capable of containing a prolapsed tissue; the inner wall of each containing cavity piece is provided with a first scale; the driving mechanism comprises an inner tube slidably arranged in the outer tube, and a far-end portion of the inner tube is respectively connected to each containing cavity piece to drive the containing cavity pieces to rotate; the endoscope canbe slidably arranged in the outer tube or the inner tube along the axial direction of the outer tube to obtain an image corresponding to the first scales on the containing cavity pieces; when the measuring instrument for prolapse of rectum is in a closed state, the multiple containing cavity pieces are relatively closed up to be able to enter into the rectum; when the measuring instrument for prolapse of rectum is in an opened state, the multiple containing cavity pieces are relatively opened up to form the containing cavity capable of allowing the prolapsed tissue to enter.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a rectal prolapse measuring instrument. Background technique [0002] Displacement of part or all of the rectal wall is called rectal prolapse. Part of the rectal wall moves down, that is, the rectal mucosa moves down, which is called mucosal prolapse or incomplete prolapse; the whole thickness of the rectal wall moves down, which is called complete prolapse. If the rectal wall moves down in the anorectal cavity, it is called internal prolapse; if it moves down to the outside of the anus, it is called external prolapse. [0003] The main clinical symptom of rectal prolapse is that there is a mass protruding from the anus. The tumor is small at the beginning, prolapses during defecation, and resets itself after defecation. Later, the tumor prolapsed gradually, and the volume increased, and it was necessary to hold it back into the anus after defecation, accompanied by incompl...

Problems solved by technology

[0005] The clinical examination methods for rectal prolapse are as follows: 1. Digital rectal examination: mainly to feel the contraction force of anal sphincter; 3. Anoscopy: directly observe the condition of the rectal mucosa, but because the anoscopy needs to use gas to support the intestinal cavity for observation, the prolapse and folding state has been destroyed and cannot be detected, only the surface condition of the rectum can be seen

None of the above three methods can quantify rectal prolapse
