Rectal prolapse measuring apparatus

Abstract

The invention discloses a rectal prolapse measuring apparatus capable of quantitatively measuring rectal prolapse. The rectal prolapse measuring apparatus comprises a shell, an endoscope, a containingmechanism and a driving mechanism; the distal end portion of the shell is provided with an outer tube; the containing mechanism comprises a plurality of cavity parts, the proximal end portion of eachcavity part is rotatably connected to the distal end portion of the outer tube; the inner wall of at least one of the cavity parts is provided with a first scale; the driving mechanism comprises an inner tube slidably along the axial direction of the outer tube arranged in the outer tube, and the distal end portion of the inner tube is respectively connected to each cavity part through a plurality of supporting rods to drive the rotation of the cavity parts; the endoscope is slidably along the axial direction of the outer tube arranged in the outer tube or the inner tube to obtain the image of a prolapsed tissue corresponding to the first scale on each cavity part; the rectal prolapse measuring apparatus has a closed state and an open state, in the closed state, the plurality of cavity parts are relatively closed up to be capable of entering a rectum; and in the open state, the plurality of cavity parts are relatively opened up to form a cavity capable of allowing the prolapsed tissueto 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
